Description

Condensate trap device

The present invention relates to a condensate trap device for use in a boiler.

In order to heat the boiler's heating water, the burner, which is a heat source, warms the air and exchanges heat with the heating water. The resulting exhaust gas can condense as the temperature decreases and phase change in the form of condensed water.

These condensates are generally acidic due to the constituents of the exhaust gases and promote corrosion of the boiler components if they are kept inside the boiler. Therefore, it is necessary to discharge it in an appropriate manner, and discharging acid wastewater without any action causes serious environmental pollution. Therefore, the condensed water is passed through the neutralization apparatus accommodating the neutralization agent, and the neutralized wastewater is discharged to the outside.

On the other hand, while condensate is being discharged in this manner, the exhaust gas remaining in the gaseous phase without condensation can be discharged together with the condensed water. However, it is very difficult to neutralize the exhaust gas in the neutralizer, and unlike the wastewater, the exhaust gas diffuses into the air together with the exhaust, resulting in serious environmental pollution.

Therefore, various trap devices have been used in the boiler industry to discharge the condensate but not the exhaust gas.

On the other hand, the neutralization device and the trap device are separately constituted, which is the main cause of increasing the size of the boiler.

SUMMARY OF THE INVENTION The present invention has been devised to solve the above problems, and it is an object of the present invention to provide a trap device in which condensate is discharged, exhaust gas is not discharged, and a neutralization device is incorporated.

The condensed water trap device according to an embodiment of the present invention includes an inlet for introducing condensed water, an internal space for accommodating a neutralizing agent for neutralizing the introduced condensed water, and a condensed water discharge port for discharging the condensed water neutralized in the internal space by the neutralizing agent A neutralizing part having a passage; A storage space for storing the condensed water directly or indirectly introduced through the condensed water passage, an outlet opening which is opened in a circular shape so that the stored condensed water can be discharged, and a spherical shape capable of shielding the outlet by being seated on the outlet Wherein the ball is spaced from the outlet by the buoyancy acting on the condensate when the condensate is received in the storage space above a critical water level so that the condensate flows through the outlet To be discharged.

As a result, neutralization of the condensed water occurs and a trap acts to block the exhaust gas and to discharge only the condensed water.

In addition, the neutralization device and the trap can be united to reduce the space occupied by the boiler.

Further, the space in which the neutralizing agent is accommodated serves as an additional trap, thereby preventing the ball-type trap from operating unstably due to the exhaust gas pressure, and forming a trap structure for shutting off the discharge of the exhaust gas.

The packing having elasticity has a specific structure in contact with the balls, and the airtightness deterioration between the balls and the packing caused by the accumulation of foreign matter can be minimized.

The foreign matter removing portion is positioned between the ball type trap and the neutralization portion, so that the amount of foreign matter contained in the condensed water discharged to the discharge port can be reduced.

It is possible to prevent the situation where the ball is separated from the ball trap and can not perform the role of the trap.

FIG. 1 is a perspective view of a condensate trap device 1 according to an embodiment of the present invention, FIG. 2 is a plan view of a condensate trap device 1 according to an embodiment of the present invention, and FIG. 4 is a front view of a condensate trap device 1 according to an embodiment of the present invention.

1 to 4, a condensate trap device 1 according to an embodiment of the present invention includes a neutralization unit 20 for neutralizing and receiving condensed water, a discharge unit 30 for discharging neutralized condensed water to the outside . The neutralization section 20 and the discharge section 30 may be provided together in the case 10 as a whole. The neutralizing part 20 and the discharging part 30 may be disposed adjacent to one another in one direction perpendicular to the vertical direction in the case 10 as a whole. The case 10 may be composed of a case body 11 and a cover 12 which forms the upper surface of the case 10.

The conventional neutralization device and the trap device as compared to the neutralization section 20 and the exhaustion section 30 have different purposes such as neutralization of discharged condensed water and discharge exhaust gas discharge respectively, And a discharge port for discharging the condensed water to the outside. However, in the condensate trap device 1 according to the embodiment of the present invention, the neutralization part 20 and the discharge part 30 are realized in one case 10 by a single device, Can be saved and an additional trap effect using neutralized condensate can be obtained.

In the embodiment of the present invention, the case 10 is described as having a cubic shape such as a rectangular parallelepiped, but the shape is not limited thereto. The condensed water trap device 1 according to the embodiment of the present invention has such a structure that the introduced condensed water can be neutralized and the discharged to the outside can be controlled on the ball trap. During the discharge of the condensed water accommodated in the condensate trap device 1, the accommodated exhaust gas is not discharged.

In this specification, the vertical direction refers to the height direction of the case 10 shown in the drawing, and the unidirectional direction of the case 10 means that the neutral partition rib 25 or the discharge partition wall 24 shown in the drawing has a vertical direction And the longitudinal direction of the case 10 means a direction perpendicular to both the vertical direction and the unidirectional direction of the case 10.

The neutralization unit 20,

The neutralization unit 20 serves to neutralize the condensed water while receiving the condensed water generated by condensation of the exhaust gas of the boiler, and to discharge the neutralized condensed water to the discharge unit 30 to be described later. Therefore, due to the action of the neutralization part 20 and the discharge part 30, the trap and the neutralization device can be unified and the space can be saved. In order to fulfill this role, the neutralization unit 20 is provided with an inlet 21 through which the condensed water flows in communication with the inlet pipe 13, an internal space 22 in which the condensed water is received, And a condensed water passage 23 which is a passage through which the refrigerant flows.

The inlet 21 is an opening through which the condensed water flows and communicates the inlet pipe 13 with the internal space 22 of the neutralization unit 20. [ The inflow pipe 13 causes the condensed water formed by condensation of the exhaust gas of the boiler to flow therein, and the condensed water is transferred to the internal space 22 through the inlet 21. Although the inlet 21 is illustrated as being formed through one side wall of the neutralization section 20, the inlet 21 is not limited thereto, but may extend through the side wall that faces the other direction .

The internal space (22) is a space surrounded by the side wall, upper surface and lower surface of the neutralization section (20), and condensed water is accommodated. In addition, the neutralization agent can be accommodated in the inner space 22, so that the neutralization can be performed on the received condensed water. The condensate produced by the condensation of the exhaust gases is generally acidic. The acidic solution should not be discharged as it is, and even if the acidic solution is stored as it is, problems such as corrosion of parts may occur. Accordingly, an alkaline neutralizing agent capable of raising the pH by neutralizing the acidic condensed water is contained in the inner space 22, and reacts with the introduced condensed water to neutralize the condensed water. As the neutralizing agent, sodium hydroxide, magnesium hydroxide, calcium hydroxide, calcium carbonate and the like may be used, but the constituent materials thereof are not limited thereto.

The condensate passage 23 is a passage through which the condensed water is discharged from the internal space 22 of the neutralization section 20 and is located at the boundary between the condensed water and the discharge section 30. In order for the condensate passage 23 to be disposed, a discharge partition wall 24 separating the neutralization portion 20 and the discharge portion 30 may be further disposed. Since the neutralization part 20 and the discharge part 30 can be disposed adjacent to each other along the direction perpendicular to the vertical direction in the case 10 of the condensate trap device 1, And the condensed water passage 23 may be formed in one portion of the discharge partition wall 24 through the discharge partition wall 24. [ The discharge partition wall 24 may be formed to extend in the vertical direction. The condensate passage (23) communicates the neutralization section (20) and the discharge section (30). Accordingly, when the condensed water is received in the internal space 22 higher than the position of the condensed water passage 23, the condensed water passage 23 conveys an excess amount of the condensed water located in the neutralized portion 20 to the discharge portion 30 It plays a role.

The condensate passage 23 may be disposed at one position of the discharge partition wall 24 higher than the position of the inlet 21 of the neutralization section 20. That is, the distance from the bottom surface of the case 10 to the condensed water passage 23 may be greater than the distance from the bottom surface of the case 10 to the inlet 21. The water head pressure resulting from the height difference D between the condensed water passage 23 and the inlet 21 is generated and the condensed water passage 23 is opened only when the water level of the condensed water reaches the position higher than the position of the inlet 21, Thereby allowing condensate to pass through the outlet. Therefore, in a state where the water level of the condensed water reaches the position higher than the position of the inlet 21, the exhaust gas can not flow into the condensed water trap device 1 through the inlet 21, An action as a trap device in which airtightness from the gas is maintained occurs.

The exhaust gas is prevented from being primarily introduced into the condensed water trap apparatus 1 of the present invention due to the positional relationship between the inlet 21 of the neutralization section 20 and the condensed water passage 23 or the intermediate passage 26 to be described later do. The water level of the condensed water accommodated in the internal space 22 may be higher than the height of the inlet 21 because the inlet 21 is positioned lower than the condensed water passage 23 or the intermediate passage 26 in the vertical direction. Therefore, when the water level of the condensed water accommodated in the inner space 22 is higher than the height of the inlet 21, the water head pressure is generated due to the difference between the water level of the condensed water and the height of the inlet 21, And can not be delivered to the condensate passage 23 or the intermediate passage 26. [

A small amount of the exhaust gas can be introduced into the condensate trap device 1 despite the above-described positional relationship. When the condensate trap device 1 is connected or the exhaust port of the built-in water heater is closed or the flue is clogged, the pressure of the combustion chamber becomes high and the pressure of the exhaust gas may be more than the head pressure. In this case, even if the condensed water blocks the inlet 21, the high-pressure exhaust gas can push the condensed water to the discharge portion 30, and the water level in the storage space 35 exceeds the critical water level, Can be discharged. The exhaust gas can be introduced into the condensate trap device 1 through the inlet 21 if the high pressure exhaust gas pushes the condensed water and the condensed water level in the internal space 22 becomes lower than the height of the inlet 21 have.

The exhaust gas which has reached the discharge portion 30 through the internal space 22 of the neutralization portion 20 and the condensed water passage 23 is discharged to the outside through the outlet portion 30 by the ball type trap structure of the discharge portion 30, (32). If the condensed water at a level lower than the critical water level is located in the storage space 35, the ball 31 covers the outlet 32, so that the exhaust gas is discharged to the outside through the outlet 32, . If the water level of the condensed water received in the storage space 35 is equal to or higher than the critical water level, the outlet 32 is blocked by the condensed water, so that the discharge of the exhaust gas to the outside through the outlet 32 is blocked by the condensed water. Accordingly, by arranging the neutralization part 20 and the discharge part 30 together, the condensed water trap device 1 according to the embodiment of the present invention can form an overall double trap structure that cuts off exhaust gas.

In addition, the condensed water passageway (23) is alternately arranged with columns and openings extending in one direction, so that foreign substances of a relatively large size can be filtered from the condensed water. Further, a porous mesh is disposed in the condensate passage 23, so that foreign matter of a relatively small size of condensed water passing through the condensate passage 23 can be filtered. 6, which is a perspective view showing a cover 12 of a condensate trap device 1 according to an embodiment of the present invention, a cover 12, which forms the upper surface of the case 10 of the condensate trap device 1, A mesh portion 121 protruding downward from a position corresponding to the condensate water passage 23 is disposed. When the cover 12 is covered on the case body 11, the mesh portion 121 is overlaid on the condensed water passage 23, so that the condensed water passing through the condensed water passage 23 can be filtered. However, an integrated mesh structure may be disposed in the condensate passage 23 itself, and the structure thereof is not limited to being formed in the cover 12. [

The neutralization unit 20 may be divided into a plurality of spaces. A case where the neutralizing part 20 is divided into the first neutralizing part 201 and the second neutralizing part 202 by the neutralizing part barrier 25 disposed in the inner space 22 Explain.

The neutral partition wall 25 may extend in the vertical direction. The neutralization partition 25 separates the first neutralization section 201 and the second neutralization section 202 and also forms an intermediate passage 26 that communicates the first neutralization section 201 and the second neutralization section 202 So that the condensed water can flow. When the level of the condensed water stored in the first neutralizing portion internal space 221 exceeds the height of the intermediate passage 26, the excessive amount of condensed water passes through the intermediate passage 26 to the second neutralizing portion internal space 222, . Accordingly, the inner space 22 is also divided into the first neutralizing portion inner space 221 and the second neutralizing portion inner space 222.

The intermediate passage 26 is also disposed at one position of the neutralizing portion partition wall 25 higher than the position of the inlet 21 so that the first neutralizing portion 201 functions as a trap similar to the condensed water passage 23 can do. The intermediate passage 26 also has a mesh structure like the condensed water passage 23, so that the condensed water can be filtered.

The first neutralizing unit 201 is provided with an inlet 21 to receive the condensed water first. Therefore, it is a space defined by the sidewall of the case 10, the upper and lower surfaces thereof, and the neutralization partition wall 25. Neutralizing agent is also contained in the first neutralizing portion internal space 221, so that the introduced condensed water can be neutralized. The neutralized condensate is delivered to the second neutralizer 202 through the intermediate passage 26 located in the neutralization bulkhead 25.

The second neutralizing unit 202 is a space located between the first neutralizing unit 201 and the discharging unit 30. The second neutralizing unit 202 is a space located between the first neutralizing unit 201 and the discharging unit 30. The second neutralizing unit 202 includes a side wall, . The second neutralization unit 202 can receive the condensed water delivered from the first neutralization unit 201. The neutralizing agent is also contained in the second neutralizing portion inner space 222, and the introduced condensed water can be neutralized again. The neutralized condensed water may be discharged to the discharge section 30 through the condensate passage 23 located in the discharge partition wall 24 provided in the second neutralization section 202.

The intermediate passage 26 located in the neutralizing partition wall 25 is arranged in a zigzag manner with the condensed water passage 23 so that the flow passage through which the condensed water flows can be extended to the entire area of the neutralizing section 20 as much as possible. 1 and 2, a straight line formed along the direction in which the condensed water passage 23 is opened and a straight line formed along the direction in which the intermediate passage 26 is opened are aligned with each other in the longitudinal direction of the case 10 Do not match. Further, the intermediate passage (26) and the condensate passage (23) are located opposite to each other along the unidirectional direction of the case (10). Thus, when passing through the second neutralizing portion 202, the condensed water does not flow directly from the intermediate passage 26 to the condensate passage 23, but flows across the second neutralizing portion 202. Therefore, the neutralizer made of small particles and the foreign material do not easily fall over, and the neutralizer and the condensate meet over a wide area.

The discharge portion 30,

The outlet 30 is a component for discharging the neutralized condensed water to the outside and includes a storage space 35 for storing condensed water, an outlet 32 for discharging the condensed water to the outside, And includes a spherical ball 31.

The storage space 35 is a space for receiving neutralized condensed water directly or indirectly from the neutralizing unit 20 through the condensate water passage 23 and storing the neutralized condensed water. Accordingly, as the condensed water is received in the storage space 35, the condensed water level in the storage space 35 can be gradually increased.

The outlet 32 is an opening formed in the storage space 35 so that the condensed water stored in the storage space 35 is communicated with the outside and the storage space 35 so as to be discharged to the outside through the discharge pipe 14. The outlet 32 is open in a circular manner and can be opened downward vertically so that the condensed water can be discharged by gravity.

A spherical ball 31 is seated in the outlet 32 to block the discharge of condensed water. The ball 31 has a diameter larger than the diameter of the outlet 32 since it has to be seated in the outlet 32. When the condensed water is received in the storage space 35 above the critical water level, the ball 31 is floated by the condensed water so as to be spaced from the outlet 32 and the condensed water flows between the ball 31 and the outlet 32 To the outlet (32). As the condensed water is discharged to the outlet 32, the condensed water level in the storage space 35 is lowered and the buoyancy acting on the ball 31 is weakened, so that the ball 31 is seated on the outlet 32 again, do. When the condensed water is discharged by the trap using the ball 31, there is no case where the ball 31 is floated up to a position higher than the condensed water level and separated from the outlet 32. Therefore, And is not discharged through the outlet 32.

The neutralization part 20 in which the above-described neutralizing agent is accommodated serves as an additional trap, thereby preventing the ball type trap formed by the ball 31 from operating unstably due to the exhaust gas pressure.

5 is an enlarged view of area A of the condensate trap device 1 according to the embodiment of the present invention. The discharge portion 30 may further include an annular packing 34 at the outlet 32. [ The packing 34 is made of a material having elasticity, and is a component for keeping the airtightness between the outlet 32 and the ball 31 better. The packing 34 has a packing base portion 341 surrounding the outlet 32 and is provided with protrusions extending like slopes from the rim of the outlet 32 toward the radial center of the outlet 32, 342). The outer circumferential surface of the ball 31 can touch the protruding protrusion 342 of the packing 34 when the ball 31 is seated in the outlet 32. [

The packing base portion 341 is a component to be combined with the outlet 32, so that it can be formed like a torus. Therefore, the packing hollow 343 is opened side by side with the outlet 32, and a flow path through which the condensed water is discharged can be formed. An annular packing seating portion 321 protruding vertically upward is further formed in the region adjacent to the outlet 32 so that the packing 34 can be seated on the inner peripheral surface of the packing seating portion 321. Since the protruding portion 342 is a component protruding from the annular packing base portion 341, the protruding portion 342 may also be formed in an annular shape.

The packing 34 is formed of a material having elasticity so that the protrusion 342 can be bent and deformed to be inclined more vertically downward by the weight of the ball 31 when the ball 31 is seated in the packing 34 have. The protrusion 342 of the packing 34 can maintain contact with the outer peripheral surface of the ball 31 irrespective of the force that the ball 31 exerts on the packing 34, The airtightness between them can be maintained well. Even if the shape of the packing 34 is not exactly an annular shape corresponding to the outer circumferential surface of the ball 31, the protrusion 342 can be deformed by the elasticity so that the contact with the outer circumferential surface of the ball 31 as a whole . Therefore, the contact area of the packing 34 with respect to the outer circumferential surface of the ball 31 is increased compared to the conventional case, and the discharge of the exhaust gas can be effectively blocked.

In the conventional case, foreign matters accumulate on the contact surface of the flat contact with the ball, and the contact surface of the ball contacts the contact surface in some areas and does not contact with the other areas, and the airtight performance between the ball and the contact surface may deteriorate with time . If the ball does not contact the contact surface well, the condensate and exhaust gas will escape through the outlet 32 without resistance, and the trap will not function.

However, the packing 34 according to the embodiment of the present invention has elasticity, so that even when foreign matter is piled up, the packing 34 and the outer peripheral surface of the ball 31 can contact each other with no gap , It is possible to prevent the airtightness from deteriorating.

In addition, since the packing 34 includes protrusions 342 having a shape like a wing which is difficult to accumulate foreign matter, a situation in which foreign matter accumulates in the packing 34 and airtightness between the packing 34 and the ball 31 is inhibited, Can also be prevented.

The discharge portion 30 may further include a ball departure prevention wall 33 surrounding the ball 31. The ball 31 can float by buoyancy of the condensate contained in the storage space 35. Therefore, it is necessary to prevent the exhaust gas 32 and the condensed water from being completely exhausted because the ball 31 can not be blocked at the other position in the storage space 35, not at the outlet 32, . Therefore, there is a need for a ball breakaway prevention wall 33 which surrounds the ball 31 and extends in the vertical direction while being disposed apart from the outer circumferential surface of the ball 31. [ It is possible to prevent the ball 31 from being deviated from the outlet 32 even if the ball 31 is seated after floating and the ball 31 can be seated well on the outlet 32 using the ball separation preventing wall 33. [

The ball departure prevention wall 33 surrounds the ball 31 so as to prevent the inside and the outside of the ball departure prevention wall 33 from communicating with each other along a direction perpendicular to the direction in which the outlet 32 is opened, As shown in Fig.

It is conceivable to use a ball trap in which a side wall partially opened at a position corresponding to the ball departure prevention wall 33 is disposed for the removal of foreign matter. With this structure, by allowing the exhaust gas to float by acting on the ball, There is a problem that the exhaust gas can escape through a gap formed between the outlets.

In an embodiment of the present invention, there is a mesh structure and a foreign matter removing unit 40 to be described later, so that the foreign matter of the condensed water is sufficiently filtered. Therefore, it is possible to use the ball break-away preventing wall 33 which does not require a side wall and which blocks the rest of the ball 31 except for the upper side. This prevents the exhaust gas from affecting the balls 31 and prevents the exhaust gas from being discharged through the outflow port 32.

The ball release preventing wall 33 may be formed in a cylindrical shape surrounding the spherical ball 31 and having an open center. The ball separation preventing wall 33 is formed in a cylindrical shape as a whole as shown in the figure and is positioned at both ends of the unidirectional direction of the case 10 with respect to the ball 31 so that the foreign matter removing barrier wall 41 or the discharge partition wall 24 and the inner wall of the case 10 can surround the ball 31 together. The inner wall of the case 10 and the foreign matter removing partition wall 41 or the discharge partition wall 24 are not surrounded by the ball 31 alone It is possible to form a wrapping space. Referring to the drawings, such a ball breakaway prevention wall 33 is formed by drawing a pair of arcs convexly opposite to each other when seen from above, and both ends of the two arcs are connected to each other by a ball 31, Thereby forming a space that can float or settle. The ball separation preventing wall 33 is formed to surround the ball 31 from a direction perpendicular to the vertical direction so that the ball 31 can ascend and descend by the buoyancy of the condensed water in the vertical direction, You may not be able to escape in other directions that are not parallel.

The foreign substance removing unit 40,

The condensate trap device 1 according to an embodiment of the present invention may further include a foreign matter removing unit 40. The foreign substance removing unit 40 is a component for removing foreign matters remaining in the condensed water. The foreign substance removing unit 40 is disposed between the neutralizing unit 20 and the discharging unit 30 so as to receive the condensed water from the neutralizing unit 20 and to discharge the introduced condensed water to the discharging unit 30. Therefore, the foreign substance removing unit 40 is disposed between the discharge partition wall 24 of the neutralization unit 20 and the side wall of the case 10, the lower and upper surfaces of the case 10, the discharge partition wall 24, Is a space defined by the foreign matter removing partition wall (41). The foreign matter removing partition wall 41 has a foreign matter removing passage 42 extending in the vertical direction and communicating with the discharge portion 30 and the foreign substance removing portion 40.

The foreign matter removing passage 42 may be disposed at a lower position than the condensate passage 23. [ 3, the height of the foreign material removing passages 42 in the vertical direction may be higher than the height of the condensate water passage 23. The condensate water passage 23 and the foreign material removal passage 42 may all be openings formed by extending vertically downward from the upper end of the case body 11 adjacent to the cover 12, And the lower end of the lower case 42 may be disposed at a lower position in the vertical direction. The level of the condensed water discharged from the foreign material removing unit 40 through the foreign material removing passage 42 to the discharging unit 30 is reduced by the foreign substance removing unit 40 from the neutralizing unit 2 through the condensed water passage 23, May be lower than the water level at which the condensed water is discharged.

The condensed water flows into the foreign matter removing unit 40 through the condensate passage 23 located at the discharge partition wall 24. The condensed water flowing into the foreign matter removing space 43 flows out to the discharge portion 30 through the foreign matter removing passage 42 located on the foreign matter removing partition wall 41. [ When the level of the condensed water received in the foreign substance removing space 43 is different from the height of the foreign substance removing passage 42 and the condensed water flows into the foreign substance removing space 43 more than the predetermined amount, To the discharge portion (30).

The condensed water flows into the foreign matter removing space 43, so that the foreign matter of the condensed water sinks to the lower surface 44 of the foreign matter removing space. 3, the lower surface 44 of the foreign matter removing space may be disposed at a position lower than the height of the outlet 32. [ The foreign matter removing passage 42 can be disposed at a position lower than the height of the condensate water passage 23 and the straight line formed along the direction in which the foreign substance removing passage 42 is opened and the direction in which the condensate water passage 23 is opened May be aligned but not coincident with each other.

The width of the foreign material removing space 43 in the longitudinal direction of the condensate trap device 1 may be narrower than the width of the first neutralizing portion internal space 221 and the width of the second neutralizing portion internal space 222. Therefore, the foreign matter settling on the lower surface 44 of the foreign matter removing space is relatively less influenced by the flow of the condensed water passing from the foreign matter removing space 43 to the discharge portion 30, The amount of foreign matter can be reduced.
