Description
Technical field
The present invention relates to a kind of heat exchanger, is a kind of plate type heat exchanger that is used for condensed type combustion gas water heater specifically.
Background technology
Condensed type combustion gas water heater is energy-efficient because of it, the technical advantage of environmental protection becomes gas heater development main flow gradually, because condensed type combustion gas water heater is energy-conservation, also is subjected to increasing consumer's favor.The secondary heat exchange device of existing condensed type combustion gas water heater, its fin substantially all adopts copper sheet to make, and described fin surface is coated with corrosion-resistant coating.But owing to contain acidic materials such as SOx, NOx in the gas heater discharged flue gas, the water vapour in the flue gas condenses into moisture content after discharging latent heat, and with material generation chemical reactions such as SOx, NOx, generate highly acid, strong oxidizing property materials such as nitric acid, nitrous acid.Therefore the fin corrosion-resistant coating can not in full force and effectly prevent the corrosion of above-mentioned acidic materials to the copper sheet heat exchanger in long-time.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the plate type heat exchanger of a kind of thermal efficiency height, long service life.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of plate type heat exchanger that is used for condensed type combustion gas water heater, it comprises the heat exchanger plates main body that sealing forms, the heat exchanger plates main body is provided with into, outlet pipe and advancing, pipe, described heat exchanger plates main body is welded by several plate package and sealing tailgate, described plate package comprises heat exchange plate and fin two parts, described heat exchange plate is a shell structure, be respectively arranged with above it and advance, the boss hole that outlet pipe communicates and with advance, the concave station hole that pipe communicates, described fin is a shell structure, be provided with respectively and boss hole above it, the concave station pore structure is opposite and be welded to each other the recess hole and the tongue hole of sealing, make to form water stream channel between heat exchange plate and the fin, form exhaust gases passes between the plate package;
As improvement of the technical scheme, bottom, the convex edge of described heat exchange plate and fin is provided with the corresponding condensed water tap in position; Described heat exchanger plates bottom part body is installed with condensed water collecting device;
As further improvement in the technical proposal, the surperficial punching press of described heat exchange plate, fin and sealing tailgate has rib.
The invention has the beneficial effects as follows: when flue gas and water enter exhaust gases passes and water stream channel respectively, water stream channel is hot for the cold conditions exhaust gases passes, during work, cold water absorbs smoke pre-heating in the exhaust gases passes in water stream channel after, the while cooled flue gas, cooled smoke is discharged outdoor by pipe, the design has realized that high efficient heat exchanging can effectively solve the etching problem of the acid condensed water heat exchanging device of band simultaneously, simultaneously, because the present invention adopts board-like project organization, so can increase or reduce the sheet number of plate-type heat-exchange plate according to the payload demand of gas heater, promptly increase or reduce the area of secondary heat exchange, to realize the optimization of heat exchange efficiency and cost.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structure cut-away view of the present invention;
Fig. 2 is the A place enlarged drawing of Fig. 1;
Fig. 3 is the B place enlarged drawing of Fig. 1
Fig. 4 is the C place enlarged drawing of Fig. 1;
Fig. 5 is STRUCTURE DECOMPOSITION figure of the present invention.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of plate type heat exchanger that is used for condensed type combustion gas water heater, it comprises the heat exchanger plates main body 1 that soldering or melting welding are sealed to form, heat exchanger plates main body 1 is provided with into, outlet pipe 2,2 ' and advance, pipe 3,3 ', described heat exchanger plates main body 1 is welded by several plate package 4 and sealing tailgate 5, described plate package 4 comprises heat exchange plate 6 and fin 7 two parts, described heat exchange plate 6 is a shell structure, be respectively arranged with above it and advance, outlet pipe 2,2 ' the boss hole that communicates 61 and with advance, pipe 3,3 ' the concave station hole 62 that communicates, described fin 7 is a shell structure, be provided with and boss hole 61 respectively above it, concave station hole 62 inverted configuration also are welded to each other the recess hole 71 and the tongue hole 72 of sealing, make to form water stream channel 41 between heat exchange plate 6 and the fin 7, form exhaust gases passes 42 between the plate package 4.
Because the high-temperature flue gas of gas heater discharging has certain aqueous vapor, thus in cooled flue gas, can separate out condensed water, thereby need to be provided with the corresponding condensed water tap 8 in position in the bottom, convex edge of heat exchange plate 6 and fin 7; In addition, for the ease of collecting discharging, described heat exchanger plates main body 1 bottom is installed with condensed water collecting device 9, and this design guarantees that effectively condensed water can not remain in the exhaust gases passes 42 and influences heat exchange efficiency.
This product is in order to postpone the flowing velocity of current and air-flow, strengthen heat exchanger effectiveness, the surperficial punching press of described heat exchange plate 6, fin 7 and sealing tailgate 5 has rib 10, rib 10 is " people " font, form by certain angle stretching certain altitude, rib 10 integral body are benchmark with plate longitudinal axis center line and form certain angle with benchmark and be symmetric mode and put.
Operation principle of the present invention is: when flue gas and water enter exhaust gases passes 42 and water stream channel 41 respectively, water stream channel 41 is that cold conditions exhaust gases passes 42 is for hot, during work, cold water absorbs smoke pre-heating in the exhaust gases passes 42 in water stream channel 41 after, the while cooled flue gas, cooled smoke is discharged outdoor by pipe 3 ', the design has realized that high efficient heat exchanging can effectively solve the etching problem of the acid condensed water heat exchanging device of band simultaneously, simultaneously, because the present invention adopts board-like project organization, so can be according to the payload demand of gas heater, increase or reduce the sheet number of plate-type heat-exchange plate, promptly increase or reduce the area of secondary heat exchange, to realize the optimization of heat exchange efficiency and cost.
