Description

[Technical field]

[0001] The present invention relates to a filter regeneration device and method for a denitrification facility, and more particularly to a filter regeneration device and method for a denitrification facility that regenerates a denitrification catalyst in a power generation facility. [Background technology]

[0002] Generally, thermal power plants are operated based on coal or oil. In recent years, regulations on environmental pollution have been strengthened, and there has been an increase in research, development, and supply of environmental equipment that can reduce the amount of pollutants emitted.

[0003] Prior art for such environmental equipment is disclosed in Patent Document 1. The registered invention is characterized by including a denitrification equipment that denitrifies exhaust gas by injecting a reducing agent into the exhaust gas discharged from a power plant.

[0004] Denitrification equipment is installed to include a denitrification catalyst, i.e., a filter, and performs denitrification of exhaust gas. The denitrification catalyst becomes poisoned by ammonium sulfate salts, dust, metal salts, etc. during the repeated denitrification process, and therefore needs to be replaced or regenerated. However, most denitrification catalysts are cleaned manually, which is problematic in that the cleaning of the denitrification catalyst is not uniform. In addition, when the denitrification catalyst is poisoned by sodium, potassium, phosphorus pentoxide, etc., it is difficult to regenerate the denitrification catalyst, which leads to problems such as environmental problems due to disposal and increased landfill costs.

[0016] The rail module may include a first rail frame and a second rail frame spaced apart from each other and arranged along a frame of the denitrification equipment in the first direction, and a connecting frame connecting the first rail frame and the second rail frame.

[0017] The power control module can move the nozzle support module in the first direction and the second direction according to a preset rule.

[0018] The power control module can control the nozzle support module to be moved across an entire top area of ​​the filter.

[0019] Meanwhile, the filter regeneration method of the denitrification equipment according to the present invention includes the steps of installing a filter regeneration device on an upper part of a filter mounted in the denitrification equipment, moving a cleaning material spray nozzle connected to the filter regeneration device and spraying dry ice toward the filter to clean the filter, and moving a coating material spray nozzle connected to the filter regeneration device and spraying a coating material toward the filter after cleaning to coat the filter.

[0020] In the cleaning step and the coating step, the cleaning material jet nozzle and the coating material jet nozzle may be moved in a first direction and a second direction intersecting the first direction.

[0021] The method for regenerating a filter of a denitrification facility may further include, after the coating step, operating a boiler connected to the denitrification facility to heat the filter installed in the denitrification facility. Effect of the Invention

[0023] In addition, the catalyst regeneration device and method for denitrification equipment according to the present invention not only removes clogged filters using dry ice, but also coats the filters with catalytically active substances to regenerate them and extend their service life, thereby solving environmental problems caused by waste landfilling and resolving the increase in landfill costs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present embodiments are not limited to the embodiments disclosed below, and may be realized in various forms, and the present embodiments are merely provided to make the disclosure of the present invention complete and to fully convey the scope of the invention to those skilled in the art. The shapes of elements in the drawings may be exaggerated in some parts for clearer explanation, and elements represented by the same reference numerals in the drawings refer to the same elements.

[0027] Fig. 1 is a perspective view showing a filter regeneration device of a denitrification facility and a denitrification facility according to the present embodiment, Fig. 2 is a perspective view showing a filter regeneration device of a denitrification facility and a denitrification facility according to the present embodiment, and Fig. 3 is a conceptual diagram showing a filter regeneration device of a denitrification facility according to the present embodiment.

[0028] As shown in Figures 1 to 3, a filter regeneration device 1000 (hereinafter referred to as the filter regeneration device) of a denitrification equipment according to this embodiment includes a regeneration unit 100 and a control unit 200, and regenerates a filter 30 installed in a denitrification equipment 10.

[0029] Here, the cross section of the filter 30 in the height direction may have a honeycomb structure, but this is for the purpose of explaining this embodiment, and the cross section of the filter 30 that is regenerated by the filter regeneration device 1000 may have various shapes, such as a plate structure or a corrugated structure.

[0030] First, the regenerating unit 100 may include a rail module 110 , a body module 120 , a nozzle support module 130 , a cleaning material jetting nozzle 140 , a cleaning material supplying module 150 , a coating material jetting nozzle 160 , and a coating material supplying module 170 .

[0031] The rail module 110 is disposed above the filter 30 to form a path through which the cleaning material jet nozzle 140 or the coating material jet nozzle 160 is transported to the upper side of the filter 30. As an example, the rail module 110 can be disposed on a frame of the denitrification equipment 10 supporting the filter 30.

[0032] Such a rail module 110 may comprise a first rail frame 111 , a second rail frame 112 , a first connecting frame 113 and a second connecting frame 114 .

[0033] Here, the first rail frame 111 and the second rail frame 112 can be fixedly disposed on the frame of the denitrification equipment 10 while being spaced apart from each other at a predetermined interval.

[0034] The first connecting frame 113 connects one ends of the first rail frame 111 and the second rail frame 112, and the second connecting frame 114 connects the other ends of the first rail frame 111 and the second rail frame 112.

[0035] The main body module 120 is connected to the rail module 110 and can be moved along the rail module 110. The main body module 120 can be moved back and forth in a first direction along the first rail frame 111 and the second rail frame 112, and the nozzle support module 130 supported in one region can be moved back and forth in a second direction intersecting the first direction.

[0036] As an example, the body module 120 may include a body frame 121 , a transport roller 122 , a support frame 123 , a first power source 124 , and a second power source 125 .

[0037] A plurality of main body frames 121 can be provided to configure a main body module 120.

[0038] The transfer rollers 122 are disposed under the main body frame 121. A plurality of transfer rollers 122 are provided to slide the main body module 120 back and forth along the first rail frame 111 and the second rail frame 112 in the first direction.

[0039] The support frame 123 is supported by the main body frame 121 and disposed long in the second direction. The support frame 123 forms a path along which the nozzle support module 130 is transported in the second direction.

[0040] The first power source 124 is supported by the main body frame 121 and provides power to the plurality of transfer rollers 122. The first power source 124 provides power to the transfer rollers 122 in response to a signal provided from the outside, so that the plurality of transfer rollers 122 can reciprocate in a first direction along the first rail frame 111 and the second rail frame 112. Here, the first power source 124 may include a motor, but is not limited thereto.

[0041] The second power source 125 is supported by the main body frame 121 and provides power to the nozzle support module 130. The second power source 125 provides power to the nozzle support module 130 in response to a signal provided from the outside, so that the nozzle support module 130 can be reciprocated in a second direction along the support frame 123. Here, the second power source 125 can provide power to the nozzle support module 130 based on a motor, a rack and pinion structure, a conveyor structure, an actuator, and the like, but the type of the second power source 125 is not limited.

[0042] The cleaning material jet nozzle 140 or the coating material jet nozzle 160 can be attached or detached together or selectively from the nozzle support module 130. The nozzle support module 130 reciprocates the cleaning material jet nozzle 140 or the coating material jet nozzle 160 in a second direction along the support frame 123 by the second power source 125.

[0043] The cleaning material injection nozzle 140 injects dry ice pellets toward the filter 30. The cleaning material injection nozzle 140 is connected to the cleaning material supply module 150 via a connection tube. The cleaning material injection nozzle 140 injects the dry ice pellets provided from the cleaning material supply module 150 toward the filter 30, so that the filter 30 can be cleaned.

[0044] The cleaning material supply module 150 supplies dry ice pellets to the cleaning material injection nozzle 140 using compressed air.

[0045] The coating material injection nozzle 160 injects an aqueous solution of vanadium pentoxide, which is a catalytic active material, toward the filter 30 that has been cleaned by the dry ice pellets. For example, if the filter 30 is not severely poisoned, the denitrification efficiency can be restored by only using the dry ice pellets, but if the filter 30 is severely poisoned, the filter 30 can be restored to a new level by coating the filter 30 with an aqueous solution of vanadium pentoxide. The coating material injection nozzle 160 is connected to the coating material supply module 170 via a connection tube. Thus, the coating material injection nozzle 160 injects the active material provided from the coating material supply module 170 toward the filter 30, so that the filter 30 is finally regenerated.

[0046] The coating material supply module 170 supplies a pre-stored aqueous vanadium pentoxide solution to the coating material injection nozzle 160 through a connecting tube.

[0047] Meanwhile, the control unit 200 can control the overall operation of the regeneration unit 100. As an example, the control unit 200 can include a power control module 210 and a supply control module 220.

[0048] The power control module 210 can be supported by the body module 120. The power control module 210 can control the first power source 124 to reciprocate the nozzle support module 130 in a first direction, and can control the second power source 125 to reciprocate the nozzle support module 130 in a second direction.

[0049] And, the supply control module 220 can be connected to the cleaning material supply module 150 and the coating material supply module 170. The supply control module 220 controls the cleaning material supply module 150 and the coating material supply module 170 to provide compressed air and dry ice pellets to the cleaning material injection nozzle 140 and to provide an active material to the coating material injection nozzle 160.

[0050] Hereinafter, the operation of the filter regeneration device of the denitrification equipment according to the present embodiment will be described with reference to the attached drawings, in which the detailed description of the above-mentioned components will be omitted and the same reference numerals will be used to describe the same components.

[0051] FIG. 4 is a flow chart showing the operation of the filter regeneration device of the denitrification equipment according to this embodiment, and FIG. 5 is a conceptual diagram showing the filter cleaning principle of the filter regeneration device of the denitrification equipment according to this embodiment.

[0052] 4 and 5, the filter regeneration device 1000 according to the present embodiment can be transported by an operator to an environment in which the denitrification equipment 10 is located in order to regenerate the filter 30 of the denitrification equipment 10. Then, the operator disassembles the denitrification equipment 10 to expose the upper portion of the filter 30.

[0053] Thereafter, the worker can install the rail module 110 on the frame of the denitrification equipment 10 (S100). Here, the first rail frame 111 and the second rail frame 112 can be installed so as to correspond to the frame interval of the denitrification equipment 10, and as one example, can be installed at intervals of 80 cm to 120 cm. Then, the worker connects one ends of the first rail frame 111 and the second rail frame 112 with a first connecting frame 113, and connects the other ends of the first rail frame 111 and the second rail frame 112 with a second connecting frame 114, thereby maintaining the rail module 110 in a solid state.

[0054] Meanwhile, when the installation of the rail module 110 is completed, the worker installs the main body module 120 on the rail module 110. At this time, the worker installs the main body module 120 so that the transfer rollers 122 can transfer along the first rail frame 111 and the second rail frame 112.

[0055] Then, the operator fastens the cleaning material injection nozzle 140 to the nozzle support module 130 to fix the cleaning material injection nozzle 140 to the nozzle support module 130. Then, the operator controls the supply control module 220 to supply dry ice pellets and compressed air from the cleaning material supply module 150 to the cleaning material injection nozzle 140 through a connecting tube (S200). Then, the operator controls the power control module 210 to cause the regeneration unit 100 to move the cleaning material injection nozzle 140 in the first direction and the second direction to perform the cleaning process on the filter 30 (S300).

[0056] For example, the regeneration unit 100 moves the cleaning material spray nozzle 140 in a first direction in response to a signal provided from the outside. Here, the moving interval of the cleaning material spray nozzle 140 may be a preset distance, but the moving interval of the cleaning material spray nozzle 140 may be adjusted by an operator.

[0057] At this time, the cleaning material injection nozzle 140 is moved a set distance in the first direction, so that the dry ice pellets and compressed air injected from the cleaning material injection nozzle 140 are injected toward the honeycomb of the filter 30, and can clean the honeycomb. Here, the injection pressure of the dry ice pellets and compressed air may be 4 bar to 8 bar, but is not limited thereto. However, if the compressed air is injected at a pressure below the set range, the poisonous substances may not be removed smoothly, and if the compressed air is injected at a pressure above the set range, the filter 30 may be damaged.

[0058] Then, the dry ice pellets and compressed air are sprayed toward the honeycomb, so that the poisoning substances in the pores of the filter 30 can be crushed and removed by the kinetic energy of the collision with the dry ice pellets. At this time, the fine particles of dry ice in the honeycomb penetrate and then sublimate (expand 500 to 800 times in volume), and the poisoning substances are discharged from the pores to the outside. In other words, the poisoning substances in the pores are discharged to the outside due to the instantaneous vacuum created by the dry ice particles passing quickly between the inner walls of the honeycomb, and the honeycomb can be regenerated.

[0059] Thereafter, when the cleaning material jet nozzle 140 completes regeneration of the honeycomb, the regeneration unit 100 can move the cleaning material jet nozzle 140 a set distance in the second direction. That is, the regeneration unit 100 can move the cleaning material jet nozzle 140 to an upper portion of an adjacent honeycomb in the second direction, and the cleaning material jet nozzle 140 jets dry ice pellets and compressed air onto the moved honeycomb to clean the honeycomb.

[0060] Thereafter, when the cleaning material spray nozzle 140 completes cleaning of one row of honeycombs arranged in the second direction, the regeneration unit 100 can move the cleaning material spray nozzle 140 a set distance in the first direction to perform regeneration on another row of honeycombs arranged in the second direction.

[0061] Meanwhile, when cleaning of the filter 30 is completed, the worker separates the cleaning material spray nozzle 140 from the nozzle support module 130 and fixes the coating material spray nozzle 160 to the nozzle support module 130 by tightening the coating material spray nozzle 160 .

[0062] Then, the operator controls the supply control module 220 so that the catalytic active material is supplied from the coating material supply module 170 to the coating material injection nozzle 160 through the connecting tube. Then, the operator controls the power control module 210 so that the regeneration unit 100 moves the coating material injection nozzle 160 in the first direction and the second direction to perform the coating process on the filter 30 (S400).

[0063] For example, the regeneration unit 100 moves the coating material spray nozzle 160 in a first direction in response to a signal provided from the outside. Here, the coating material spray nozzle 160 may be moved by a preset distance, but the coating material spray nozzle 160 may be moved by an operator to adjust the distance.

[0064] At this time, the coating material spray nozzle 160 is moved a set distance in the first direction, so that the active material sprayed from the coating material spray nozzle 160 is sprayed toward the honeycomb of the filter, thereby coating the honeycomb.

[0065] Thereafter, when the coating material spray nozzle 160 completes coating the honeycomb, the regeneration unit 100 can move the coating material spray nozzle 160 a set distance in the second direction. That is, the regeneration unit 100 can move the coating material spray nozzle 160 to an upper portion of an adjacent honeycomb in the second direction, and the coating material spray nozzle 160 sprays an active material onto the moved honeycomb to coat the honeycomb.

[0066] Thereafter, when the coating material spray nozzle 160 completes coating one row of honeycombs arranged in the second direction, the regeneration unit 100 can move the coating material spray nozzle 160 a set distance in the first direction to coat another row of honeycombs arranged in the second direction.

[0067] Finally, when the regeneration of the filter 30 is completed, the operator stops the operation of the regeneration unit 100 and separates the filter regeneration device 1000. Then, the operator operates a boiler (not shown) connected to the denitrification equipment 10 (S500).

[0068] Generally, in regenerating the filter 30 separated from the denitrification equipment 10, a separate drying and firing process may be required when coating. However, in the regeneration unit 100 according to the present embodiment, the filter 30 is regenerated while attached to the denitrification equipment 10, so that separate drying and firing processes are not required, and the filter 30 can be dried and fired by operating the boiler of the denitrification equipment 10. In other words, the drying and firing are performed using waste heat from the exhaust gas discharged from the boiler, so that separate drying and firing processes are not required.

[0069] As described above, the catalyst regeneration device and method for the denitrification facility according to the present invention has the effect of automatically moving the injection nozzle to wash and coat the filter, improving the regeneration efficiency and shortening the regeneration time.

[0070] In addition, the catalyst regeneration device and method for denitrification equipment according to the present invention not only removes clogged filters using dry ice, but also coats the filters with an active substance to regenerate them, thereby extending their service life, thereby solving environmental problems caused by waste landfills and resolving the increased cost of landfilling.

The scope of protection of the present invention is limited only by the matters described in the claims, and a person having ordinary skill in the technical field of the present invention can improve and modify the technical idea of ​​the present invention in various forms.
