Description

A dust collector for removing fine dust in a high-temperature environment

The present invention relates to a dust collector that filters and collects particulate dust from exhaust gas, and more particularly, fine dust in a high-temperature environment in which a filter filters particulate dust of exhaust gas and exhausts dust accumulated in the filter through counter airflow It relates to a dust collector for removing

As is well known, dust collectors are installed in workplaces, factories, power plants, and automobile repair shops that generate a lot of particulate pollutants and dust (hereinafter 'dust'), It is a facility that collects and removes dust contained in gas') and discharges clean gas to the outside.

Such a dust collector is largely divided into an electric dust collector and a filter dust collector according to a dust collection method. Among them, the filter dust collector filters and collects dust in exhaust gas using a filter.

The filter for performing the filtration function is composed of a bag filter, a cartridge filter, a candle filter, etc. according to the shape and arrangement structure. The filter is made of a fiber-based filter cloth or ceramic for dust filtering, and the components, structure, and manufacturing method constituting the filter cloth or ceramic may vary.

In general, since a dust collector filters exhaust gas at a high temperature of 300° C. or more generated in the combustion process, the dust collector, particularly a filter through which the exhaust gas directly passes, is continuously heated by the exhaust gas during the filtration process. Therefore, the filter for filtration, particularly the fibrous filter cloth, may be thermally deformed and deteriorated by high temperature, and this modification was a cause of weakening the dust collection performance and shortening the life of the filter.

In order to solve the above problem, a ceramic material having excellent heat resistance is applied to the filter of the conventional dust collector.

However, the conventional ceramic filter forms a tubular shape with an open top and forms a suspended installation structure in which only the upper part of the dust collector is fixed to the upper frame. In order to reduce the weight burden, it was downsized or the number of installations was limited, and there was also the instability that only the upper part of the ceramic filter had to support its own load. Moreover, as dust accumulates on the ceramic filter during the exhaust gas filtration process, the load on the ceramic filter increases, so there is also a problem in that the cycle of dust removal work has to be reduced for fixed stability.

In order to solve this problem, the conventional dust collector fixes the upper part of the ceramic filter to the upper cap (upper frame) in the enclosure, the lower part is fixed to the lower cap (lower frame), and the upper cap and the lower cap are formed in a rope or rod shape. A technology has been developed in which the upper part and the lower part share the load that the ceramic filter has to support by fixing it in the vertical direction using a connecting device.

However, since the lower cap is fixed to the upper cap through a connector, the problem that the upper cap bears the entire load of the ceramic filter still persisted. , which increases the manufacturing cost of the dust collector.

On the other hand, unlike the filter cloth, the ceramic filter has a fixed shape and the coefficient of thermal expansion is different from that of the metallic upper cap and the lower cap. Therefore, the contact range between the upper and lower caps and the ceramic filter should be small, and it is desirable to minimize heat transfer between the upper and lower caps.

However, in the conventional dust collector, since the upper cap and the lower cap are directly connected up and down by a plurality of connecting devices, heat conduction between the upper cap and the lower cap is advantageous, and the composition of the heating environment during filtration is aggravated, and both the upper and lower parts of the ceramic filter are There was also a problem in that the upper and lower caps deformed by heat were damaged by applying an external force to the ceramic filter because they were respectively bound to and contacted with the upper and lower caps.

In general, the filtration type dust collector performs a dust removal process to remove the dust adhering to the filter when the filtration process is completed. However, in the conventional dust collector, since the filtration process and the dust removal process are separate processes, exhaust gas filtration had to be periodically stopped for the dust removal process. Therefore, taking into account the stopped filtration process, the previous work to exhaust the exhaust gas has also been stopped. After all, during exhaustion, there was an unreasonable need to either discharge exhaust gas into the air without substantial filtration or stop production by stopping the operation itself.

Accordingly, the present invention is to solve the above problem, and the ceramic filter of the dust collector can maintain a stable fixed state and minimize heat transfer by filtration of exhaust gas at high temperature to solve problems such as thermal expansion in a high-temperature environment. It is an object to be solved by providing a dust collector for removing dust.

1 is a view schematically showing an embodiment of a dust collector according to the present invention.

Referring to FIG. 1, the dust collector 100 of the present invention is a housing 110 that continuously sucks the dust impregnated gas introduced through an inlet pipe P1 and a backflow prevention pipe 210 from an external or internal boiler, etc. And, the tubular ceramic filter 120 for filtering the dust of the inhaled dust-containing gas, the lower frame 130 for fixing the lower side of the ceramic filter 120, and the upper frame 140 for fixing the upper side of the ceramic filter 120 ), a bracket 150 installed to seat the lower frame 130, and an adjustment bolt 160 connected to the bracket 150 to support the lower frame 130 to elevate the lower frame 130 according to the rolling direction ; see FIG. 2).

Here, the housing 110 constitutes an inlet of the dust-containing gas introduced through the backflow prevention pipe 210 and an exhaust port through which the filtered gas in which the dust of the dust-containing gas is filtered through the ceramic filter 120 is discharged. In addition, a guide panel 111 for guiding the impregnated gas to the floor is installed at the inlet so that the impregnated gas rises in the direction of the ceramic filter 120 via the floor. In this process, the dust present in the dust-containing gas is first filtered by its own weight at the bottom. In general, the exhaust port is located in the upper portion of the housing 110 so that only the gas that has passed through the ceramic filter 120 is exhausted, and the inlet is located in the lower portion so that the dust impregnated gas passes through the floor.

On the other hand, the bottom of the housing 110 is formed with an inclined surface so that the dust-containing gas introduced from the inlet rotates and rises without a vortex. The housing 110 of this embodiment is formed with a first inclined surface 112 facing the floor at the inlet, and a second inclined surface 113 is formed on the dust outlet 114 . Accordingly, the dust-containing gas introduced from the inlet is guided to the bottom of the housing 110 along the guide panel 111 and the first inclined surface 112 , and the dust-containing gas that has moved to the floor rises along the second inclined surface 113 . Thus, it moves to the ceramic filter 120 without a vortex.

Subsequently, at least one outlet 114 through which the dust accumulated on the bottom of the housing 110 is discharged is formed on the second inclined surface 113 , and a discharge pipe is piped to the outlet 114 . Therefore, the strong force of the dust-containing gas induced to pass through the bottom of the housing 110 moves the dust deposited on the floor to the outlet 114 while pushing it to the outlet 114, and the dust moved in this way is discharged through the outlet 114 through the outlet pipe. is emitted as As a result, the dust filtered by the dust collector 100 can be separated and discharged without a separate hopper configuration.

The ceramic filter 120 filters the impregnated gas in the housing 110 . To this end, the dust collector 100 of the present embodiment has a long tube shape, and a plurality of pieces are arranged in a uniformly arranged structure. In order to fix the plurality of ceramic filters 120 listed in this way, the lower and upper sides of the ceramic filter 120 are supported by the lower frame 130 and the upper frame 140 , respectively. In the dust collector 100 of the present embodiment, the lower frame 130 closes the lower opening of the ceramic filter 120 so that the dust-containing gas flows into the side of the ceramic filter 120 and is arranged in a grid shape. The structure of the lower frame 130 will be described in more detail below.

The upper frame 140 is fixed to the housing 110 , and the filtered gas flowing into the side of the ceramic filter 120 rises through the hollow of the tubular ceramic filter 120 and is exhausted. To this end, the upper frame 140 has a panel shape in which openings 140a (refer to FIG. 6) communicating only with the hollow of the ceramic filter 120 are arranged, and the upper part of the housing 110 in which the exhaust port is located and the housing in which the inlet is located ( 110) It is installed in the housing 110 so that the lower part of the hollow is partitioned.

As described above, the upper frame 140 is fixed to the housing 110 , while the lower frame 130 has a movable structure. Moreover, the lower frame 130 and the upper frame 140 form an independent structure without connecting means between each other. Therefore, a means for supporting the lower frame 130 and pressing the ceramic filter 120 to be in close contact with the upper frame 140 is required. The dust collector of the present invention includes a bracket 150 fixed to the housing 110 and; It includes an adjustment bolt 160 (refer to FIG. 2) for supporting the lower frame 130 to elevate based on the bracket 150.

As is well known, the threaded adjustment bolt 160 moves along the rolling direction based on the female screw, so the adjustment bolt 160 bound to the female screw configured to penetrate up and down in the bracket 150 moves up and down according to the rolling direction. Move. Therefore, when the end of the adjustment bolt 160 is disposed to support the lower frame 130 , the lower frame 130 also moves up and down according to the vertical movement of the adjustment bolt 160 . As a result, the combined structure of the ceramic filter 120 and the lower frame 130 is raised and lowered along the rolling direction of the adjustment bolt 160 , while the upper side of the ceramic filter 120 is pressed against or spaced apart from the upper frame 140 .

In the dust collector 100 of the present invention described above, the dust-containing gas introduced into the housing 110 through the inlet is guided by the guide panel 111 on the first inclined surface 112 and the second inclined surface 113. The filtered gas moved and filtered through the side of the ceramic filter 120 and the dust filtered through the filtration moves along the hollow of the ceramic filter 120 through the opening 140a and the exhaust port of the upper frame 140 . is emitted The filtered gas thus discharged moves along the exhaust pipe P2 connected to the exhaust port and is discharged through the exhaust structure 230 such as a chimney.

For reference, the airflow of the impregnated gas and the filtered gas through the backflow prevention pipe 210, the housing 110, and the exhaust structure 230 is formed by driving the exhaust pump 220, and in this embodiment, the exhaust pump 220 ) is installed in the discharge structure 230, but may be installed in the dust collector 100 or may be installed before that.

2 is an exploded perspective view illustrating a coupling structure of a lower frame supporting a ceramic filter configured in the dust collector according to the present invention, FIG. 3 is an enlarged cross-sectional view of part A of FIG. 1 , and FIG. 4 is a dust collector according to the present invention. It is a plan view showing an embodiment of the lower frame configured in the device.

1 to 4 , the lower frame 130 of the present invention includes a first section steel 131 supporting and supporting the lower side of the ceramic filter 120 , and a lower side of the first section steel 131 supporting and supporting the lower side of the ceramic filter 120 . It is composed of a second section steel 132 and a mover 133 installed in the second section steel 132 with the end of the screw 161 (refer to FIG. 5) rollable.

Each component of the lower frame 130 will be described in more detail.

The first section steel 131 directly supports and supports the lower side of the silicon filter 120 as shown in FIG. 3 , and the lower opening of the tubular silicon filter 120 is closed. For the closing, it is preferable that the first section steel 131 has a flat top surface and a cross-sectional structure of a '∩' structure capable of supporting the heavy silicon filter 120 . In addition, the silicon filter 120 reinforces the blocking film 121 in the opening at the lower side of the silicon filter 120 so that a vent through which the impregnating gas flows other than the side surface is not formed between the first section steel 131 and the first section steel 131 ) and the blocking film 121 and the lower side of the silicon filter 120, a sealing 122 process may be performed.

The first section steel 131 of this embodiment forms a beam structure of a certain length to integrally support a plurality of silicon filters 120 arranged in a line.

The second section steel 132 supports and supports the lower side of the first section steel 131, and the first section steel 131 and the second section steel 132 are arranged to cross each other. At this time, since the second section steel 132 supports the plurality of first section steels 131 , the lower frame 130 in the form of a grid as shown in FIG. 4 through the combination of the first section steel 131 and the second section steel 132 . create Therefore, the dust-containing gas introduced through the inlet of the housing 110 is introduced and filtered into the silicon filter 120 via the lower frame 130 . In the second section steel 132 of the present embodiment, a binding groove 132a is formed on the upper surface to prevent the first section steel 131 from being separated. Therefore, the first section steel 131 and the second section steel 132 maintain a grid shape at regular intervals without separation.

The mover 133 serves as an adapter for dispersing the pressure applied by the second section steel 132 supported by the adjusting bolt 160 and maintaining a stable bond between the adjusting bolt 160 and the second section steel 132 . .

Since the adjusting bolt 160 of this embodiment supports and supports the edge portion of the lower frame 130 , the mover 133 is fixed to the end of the second section steel 132 . To this end, a fixing hole 132b is formed at the end of the second section steel 132, and the mover 133 disposed under the second section steel 132 is fastened with pins or bolts through the fixing hole 132b. However, the second section and the mover 133 are not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the following claims.

5 is a cross-sectional view illustrating the operation of the component shown in part B of FIG. 1 , and FIG. 6 is a cross-sectional view illustrating the operation of the component shown in part C of FIG. 1 .

Referring to FIGS. 2 and 5 to 6 , as described above, the adjusting bolt 160 of this embodiment has the screw 161 passing through the bracket 150 fixed to the housing 110 so that the end is the mover 133 . It is inserted into the insertion groove (133a) of the. Therefore, according to the rolling direction of the adjustment bolt 160, the mover 133 moves up and down based on the bracket 150, and the end of the adjustment bolt 160 is inserted into the insertion groove 133a of the adjustment bolt 160. Move up and down by moving up and down. At this time, the screw 161 end 161a (refer to FIG. 8 ) of the adjustment bolt 160 inserted into the insertion groove 133a of the mover 133 idles in the insertion groove 133a regardless of the rolling of the adjustment bolt 160 . It is preferred that the screw thread is absent.

A process in which the adjustment bolt 160 is connected to the mover 133 will be sequentially described with reference to FIG. 5 .

Referring to (a) of FIG. 5 , the second section steel 132 of the lower frame 130 is seated on the bracket 150 regardless of whether the silicon filter 120 is installed. At this time, the two nuts N1 and N2 may be connected to the screw 161 so that the adjusting bolt 160 bolted to the bracket 150 is not loosened.

Referring to (b) of FIG. 5 , the adjustment bolt 160 is rolled to move upward so that the end of the screw 161 is inserted into the insertion groove 133a of the mover 133 . At this time, it is preferable that the end end of the screw 161 comes into close contact with the ceiling surface of the insertion groove 133a. For reference, since the two nuts N1 and N2 rotate in the same direction together with the screw 161 in the process of rolling the adjusting bolt 160 to move upward, the adjusting bolt 160 without being caught by the bracket 150 . of smooth rolling is possible.

5 (c), when the upper side of the silicone filter 120 comes into close contact with the upper frame 140 while the lower frame 130 rises through continuous rolling of the adjustment bolt 160, two nuts (N1, N2) is rolled in the reverse direction to be in close contact with the bracket (150). As a result, the adjustment bolt 160 maintains its current position without being loosened by its own reverse rolling, and through this, the lower frame 130 does not descend and maintains its own height.

On the other hand, referring to the drawing (a) of FIG. 6 , the upper side is inserted into the opening 140a of the upper frame 140 through the rise of the silicone filter 120 , and through this, the hollow shape filtered by the silicone filter 120 is inserted. The filtered gas may be introduced through the opening 140a.

In the upper frame 140 of the present embodiment, a ring-shaped packer 141 is reinforced in the opening 140a so that a hole is not formed between the silicon filter 120 and the upper frame 140 . The packer 141 has a fitting groove 141a in which the upper side of the silicon filter 120 is engaged and is formed in the lower portion. In addition, a sealing type finishing material 142 is installed on the inner surface of the fitting groove 141a so that a gap does not occur between the upper side of the silicon filter 120 and the packer 141 .

As a result, the upper side of the silicon filter 120 is tightly bound to the opening 140a of the upper frame 140 without a gap, and through this, the dust-containing gas is introduced only to the side of the silicon filter 120, so that the high-quality filtered gas after filtration is discharged through the exhaust port of the housing 110 .

7 is a view schematically showing another embodiment of the dust collector according to the present invention.

1 to 7, in the dust collector 100 of the present invention having the above-described structure, the dust of the dust-containing gas separated by the silicon filter 120 moves to the outlet 114 by the strong force of the dust-containing gas and is discharged Therefore, dust is removed at the same time as the dust-containing gas filtration. Therefore, since a separate hopper for dust collection is unnecessary, the height of the housing of the dust collector can be remarkably reduced, and thus, it can be manufactured in a multi-layer structure in which separate housings 110 and 110 ′ are stacked as shown in FIG. 7 .

For the multi-layer structure, the dust collector 100 of this embodiment comprises inlet pipes P1 and P1' and backflow prevention pipes 210 and 210' for each enclosure 110 and 110', respectively, and inlet pipes P1 and P1 ') and the backflow prevention pipes 210 and 210' are connected in series so that the dust impregnated gas introduced into one inflow path passes through the inflow pipes P1 and P1' and the backflow prevention pipes 210 and 210' to the enclosure 110 , 110').

In addition, the exhaust pipes P2 and P3 for each of the enclosures 110 and 110' are also connected in series, so that the filtered gas is discharged through one exhaust path.

On the other hand, the discharge pipes 114a and 114a' of the discharge ports 114 formed in the enclosures 110 and 110', respectively, are connected in parallel, and the dust that has moved through the discharge pipes 114a and 1114a' is introduced into the small dust collector 240. It is collected after the second dust collection. As described above, in the dust collector 100 of the present invention, since the dust accumulated in the housing 110, 110' is discharged to the outlet 114 by the dust-containing gas, a small amount of the dust-containing gas is discharged through the outlet 114 during the discharge process. It can be introduced into the small dust collector 240 through the. Therefore, the small dust collector 240 collects the dust-containing gas discharged to the outlet 114 together with the dust as a secondary dust.

On the other hand, it further includes a blower 250 for taking out the dust to inhale the filtered gas of the small dust collector 240 . The blower 250 for taking out the dust accelerates the dust discharge by generating a suction force at the outlet 114 of the housing 110 , and the filtered gas of the small dust collector 240 is rapidly exhausted.

FIG. 8 is an exploded perspective view showing the coupling structure of the mover and the adjusting bolt configured in the dust collector according to the present invention in a cross-sectional view of the mover, and FIG. 9 is a cross-sectional view showing the rolling state of the adjusting bolt coupled to the mover.

2, 5 and 8 to 9, in the dust collector 100 of the present invention, the lower frame 130 is raised and lowered through the rolling of the adjusting bolt 160 as described above. However, since a plurality of adjustment bolts 160 are installed on the edge of the lower frame 130, if all the adjustment bolts 160 are not rolled at a constant rotation angle at the same time, the lower frame 130 is inclined and the adjustment bolt 160 and the rear could be wrong

Accordingly, one or two or more elastic bands ( 133c). Here, since the designated position is a standard that the adjustment bolt 160 can be rolled once, the elastic band 133c hangs the adjustment bolt 160 while the operator is rolling the adjustment bolt 160 and stops, the operator is currently Stop the rolling of the adjusting bolt 160 and roll the adjusting bolt at a different position until the corresponding elastic band hangs. In this way, the adjustment bolt 160 is rolled and the lower frame 130 is raised or lowered.

To this end, in the elastic band 133c of the present invention, the elastic band 133c is formed to protrude into the insertion groove 133a of the mover 133 . Therefore, when the end portion 161a of the screw 161 is inserted into the insertion groove 133a, the side surface of the end portion 161a presses the protruding portion of the elastic band 133c in Fig. 9 (a) and (b) views. As shown, the elastic band 133c is deformed.

On the other hand, a section of the side of the end 161a of the screw 161 is formed to be concave (161b) so that the deformed elastic band 133c is restored to a circular shape as shown in FIG. 9(c). Therefore, when the elastic band (133c) reaches the concave (161b) section during the rolling of the adjustment bolt (160), the elastic band (133c) stops the rolling of the adjustment bolt (160) while protruding elastically.

In addition, if the end 161a of the screw 161 is not yet inserted into the insertion groove 133a, the elastic band 133c is in a protruding state, so the concave 161b to insert the screw 161 into the insertion groove 133a The section should fit the elastic band (133c). As a result, in order to insert the adjustment bolt 160 into the insertion groove 133a, the concave 161b section must be aligned with the elastic band 133c, so that all the adjustment bolts 160 supporting the lower frame 130 have a certain position. You can start rolling with a point in time.

10 is a partial cross-sectional view schematically showing another embodiment of the dust collector according to the present invention.

1 and 10, in the dust collector 100 of the present invention, a plurality of ceramic filters 120 are arranged side by side; An exhaust pump 220 for pumping the impregnated gas to be sucked into the ceramic filter 120 , a plurality of nozzles 171 installed for each ceramic filter 120 , and a compressor that pressurizes the nozzle 171 to eject high-pressure air 180, a valve 172 for opening and closing the nozzle 171, and a controller for controlling the valve 172 so that only a portion of the plurality of nozzles 171 is partially opened while the exhaust pump 220 and the compressor 180 are driven ( 190).

A plurality of ceramic filters 120 built into the housing 110 suck the dust-containing gas by driving the exhaust pump 220 . At this time, when the valves 172 of some of the nozzles 171 arranged for each ceramic filter 120 are opened, high-pressure air moves and ejects from the compressor 180 communicating with the nozzles 171 . That is, at the moment the valve 172 is opened, the corresponding nozzle 171 ejects high-pressure air to the corresponding ceramic filter 120 to reverse the impregnated gas. In this process, the dust-containing gas and high-pressure air flowing into the ceramic filter 120 exhaust the dust caught in the ceramic filter 120 , and the dust falls to the bottom of the housing 110 and is deposited. Of course, since the controller 190 opens only some of the plurality of valves 172 arranged for each nozzle 171, the ceramic filter 120 can be exhausted during filtration, and through this, a separate exhaust process is performed after the filtration process. unnecessary

The controller 190 according to the present embodiment may control the valve 172 to open and close at a specified time unit through a timer function, may set the number of valves 172 to be opened, and may also set the opening order.

Since the dust collector 100 of the present invention simultaneously performs the dust collection process and the dust removal process, the controller 190 opens and closes the valve 172 of the nozzle 171 while the exhaust pump 220 and the compressor 180 are driven.

In the detailed description of the present invention described above, although it has been described with reference to preferred embodiments of the present invention, those skilled in the art or those having ordinary knowledge in the art will have the spirit of the present invention described in the claims to be described later And it will be understood that the present invention can be variously modified and changed without departing from the technical scope.
