Description

Technical Field

[0001] The invention relates to the field of desulfurization and dust removal equipment, in particular to desulfurization and dust removal equipment for industrial kilns. Background Art

[0002] Industrial kilns often require desulfurization and dust removal equipment during the production and processing process. However, the existing industrial kiln desulfurization and dust removal equipment has the disadvantage of poor dust removal effect, which results in the inability to effectively desulfurize the flue gas generated by the kiln, polluting the living environment, being inconvenient to use, reducing the efficiency of the dust removal equipment, and reducing the use effect of the kiln.

[0003] According to a patent document with an existing publication number of CN211159254U, a dust removal device for desulfurization of an industrial kiln is disclosed, which includes a heating kiln, a movable door is movably connected to the front of the heating kiln, a supporting foot is fixedly connected to the bottom of the heating kiln, a controller is fixedly connected to the left side of the heating kiln, a connecting pipe is fixedly connected to the right side of the heating kiln, a dust removal furnace is fixedly connected to the right end of the connecting pipe, a dust collector is fixedly connected to the left side of the dust removal furnace, and a connecting foot is fixedly connected to the bottom of the dust removal furnace. When the technical solution is in use, the smoke in the heating kiln is circulated to the dust removal through the connecting pipe. In the dust furnace, desulfurization liquid is pumped into the hose through a micro water pump, and the desulfurization liquid can be smoothly pumped into the top of the hose by opening the water outlet valve. The hose will pump the desulfurization liquid into the sprinkler nozzle, and the sprinkler nozzle will spray the desulfurization liquid on the top of the first filter plate. The desulfurization liquid will flow down through the filter holes opened in the first filter plate, and the dust in the flue gas can be flushed onto the top of the second filter plate, thereby achieving the purpose of flue gas desulfurization. Regarding the above technical scheme, although this scheme realizes the desulfurization of flue gas, after filtering the dust in the later stage, the dust on the filter plate cannot be cleaned in time and discharged in the later stage, which is inconvenient during use. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a desulfurization and dust removal equipment for industrial kilns to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. When in use, the flue gas enters the local filter cartridge through the ring seat and the separator seat for filtration. When the local filter cartridge has been filtering for a long time, the ring seat and the separator seat move. The movement adjusts the exhaust filtration position of the flue gas on the one hand, and on the other hand, the movement of the separator seat and the ring seat facilitates the scraping and cleaning of the dust on the surface of the filter cartridge.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a desulfurization and dust removal equipment for industrial kilns, including a base, a furnace body is fixed on the base, an exhaust pipe is fixed on the top of the furnace body, an air collecting pipe is fixed at one end of the exhaust pipe, an exhaust pipe is fixedly installed on one side of the air collecting pipe, an air pump is fixed on the top of the furnace body, one end of the exhaust pipe is fixed on the air pump, an air intake pipe is fixed on the air pump, a filter tank is fixed at one end of the air intake pipe, the filter tank is fixedly installed on the base, a support pipe is fixed on the top of the filter tank, a desulfurization box is fixed on the base, and one end of the support pipe is fixed inside the desulfurization box.

[0006] Furthermore, an air outlet is fixed on the top of the desulfurization box, a sewage pipe is fixedly installed on the side of the desulfurization box, a dust exhaust pipe is fixed on the side of the filter tank, and a fan is fixedly installed on the dust exhaust pipe.

[0007] Furthermore, a lifting mechanism is fixedly installed on the top of the filter tank, a movable column is installed on the lifting mechanism, a cavity is opened inside the filter tank, and an inner tank is fixed inside the cavity.

[0008] Furthermore, a filter cartridge is fixedly mounted on the inner tank, a ring seat is movably mounted on the side of the filter cartridge, the ring seat is movably mounted inside the cavity, and the ring seat is fixed to one end of the movable column.

[0009] Furthermore, a spacer seat is installed between the ring seats, a fixing column is welded between the spacer seat and the ring seats, and one end of the inner liner is movably installed on one end of the support tube.

[0010] Furthermore, a motor box is fixed inside the desulfurization box, a driving motor is fixedly installed inside the motor box, a stirring rod is installed on the driving motor, and a water inlet pipe is fixedly installed on the top of the desulfurization box.

[0011] Furthermore, a support seat is fixed inside the desulfurization box, an opening is opened on the support seat, a filter plate is fixed on the top of the support seat, and a sealing block is fixed on the side of the support seat.

[0012] Furthermore, a groove is formed on the inner wall of the desulfurization box, a movable frame is movably installed inside the groove, the inner wall of the movable frame cooperates with the sealing block, and a sealing plate is fixed on the inner wall of the groove.

[0013] Furthermore, the sealing plate is in contact with the outer wall of the movable frame, a pushing mechanism is fixed inside the desulfurization box, and one end of the pushing mechanism is fixed on the movable frame.

[0014] Furthermore, the support tube is fixedly provided with air outlet holes, and the air outlet holes are distributed at the bottom of the stirring rod.

[0015] Beneficial effects of the present invention:

[0016] 1. This type of desulfurization and dust removal equipment is used in industrial kilns. When in use, the flue gas passes through the ring seat and the separator seat into the local filter cartridge for filtration. When the local filter cartridge has been filtering for a long time, the ring seat and the separator seat move. On the one hand, the movement adjusts the exhaust filtration position of the flue gas, and on the other hand, the movement of the separator seat and the ring seat facilitates the scraping and cleaning of the dust on the surface of the filter cartridge.

[0017] 2. This type of desulfurization and dust removal equipment is used in industrial kilns. The gas after dust removal and filtration enters the interior of the desulfurization box through the support pipe, and the flue gas is sprayed into the desulfurization liquid through the outlet hole. The desulfurization liquid removes the sulfur contained in the gas. When the gas moves in the desulfurization liquid, the stirring rod drives the bubbles to break. The broken gas can better contact with the desulfurization liquid at different positions for rapid desulfurization.

[0018] 3. This type of desulfurization and dust removal equipment is used in industrial kilns. The pushing mechanism pushes the movable frame to move up and down. When the movable frame moves upward, the liquid between the movable frame and the support seat moves upward. The liquid moves upward to complete the backwashing of the surface of the filter plate to avoid the blockage of the filter plate by the dust in the flue gas. In addition, the up and down movement of the movable frame controls the height of the liquid level. After the liquid level is adjusted, the time for the gas to move in the liquid is adjusted. Later, the movable frame falls downward, and the liquid on the top of the filter plate moves to both sides. The movement of the liquid to both sides drives the dust to fall on the movable frame. Finally, the movable frame cooperates with the sewage pipe to facilitate the discharge of waste liquid. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In this embodiment, an air outlet pipe 15 is fixed on the top of the desulfurization box 13, a sewage pipe 14 is fixedly installed on the side of the desulfurization box 13, a dust exhaust pipe 11 is fixed on the side of the filter tank 8, a fan 12 is fixedly installed on the dust exhaust pipe 11, a lifting mechanism 9 is fixedly installed on the top of the filter tank 8, the lifting mechanism 9 is a linear reciprocating electric push rod, the lifting mechanism 9 pushes the ring seat 19 up and down through a movable column 20, the lifting mechanism 9 is installed with a movable column 20, a cavity 16 is opened inside the filter tank 8, an inner liner 17 is fixed inside the cavity 16, a filter cartridge 18 is fixedly installed on the inner liner 17, a ring seat 19 is movably installed on the side of the filter cartridge 18, the ring seat 19 is movably installed inside the cavity 16, the ring seat 19 is fixed at one end of the movable column 20, the movable column 20 drives the ring seat 19 to move up and down, the up and down movement of the ring seat 19 changes the position of the partition seat 21, and the position of the flue gas filtration is adjusted.

[0029] In this embodiment, a partition seat 21 is installed between the ring seats 19, and a fixing column 22 is welded between the partition seat 21 and the ring seat 19. One end of the inner tank 17 is movably installed on one end of the support tube 10. A motor box 24 is fixed inside the desulfurization box 13, and a driving motor 25 is fixedly installed inside the motor box 24. A stirring rod 26 is installed on the driving motor 25. A water inlet pipe 23 is fixedly installed on the top of the desulfurization box 13. A support seat 28 is fixed inside the desulfurization box 13, and an opening 30 is opened on the support seat 28. A filter plate 31 is fixed on the top of the support seat 28, and a sealing block 29 is fixed on the side of the support seat 28. The sealing block 29 contacts with the inner wall of the movable frame 32 for sealing, so as to effectively prevent the desulfurization liquid from leaking from the inside of the groove 33.

[0030] In this embodiment, a groove 33 is formed on the inner wall of the desulfurization box 13, and a movable frame 32 is movably installed inside the groove 33. The inner wall of the movable frame 32 cooperates with the sealing block 29. A sealing plate 34 is fixed on the inner wall of the groove 33, and the sealing plate 34 contacts the outer wall of the movable frame 32. A pushing mechanism 35 is fixed inside the desulfurization box 13, and one end of the pushing mechanism 35 is fixed on the movable frame 32. An air outlet 27 is fixedly installed on the support tube 10, and the air outlet 27 is distributed at the bottom of the stirring rod 26. The pushing mechanism 35 is a linear reciprocating electric push rod. The pushing mechanism 35 pushes the movable frame 32 up and down. The movable frame 32 moves upward to control the liquid level and facilitates the discharge of waste liquid at a later time.

[0031] When the device is in use, the gas generated by the combustion inside the furnace body 2 is concentrated into the inside of the gas collecting pipe 4 through the exhaust pipe 3, and the air pump 6 generates suction force, which causes the smoke to enter the inside of the intake pipe 7 through the exhaust pipe 5. The gas in the intake pipe 7 enters the inside of the filter tank 8. Before the gas enters, the position of the gas filtered on the filter cartridge 18 is controlled, and the lifting mechanism 9 is started to drive the ring seat 19 to move upward, and the ring seat 19 drives the partition seat 21 to move upward. After the partition seat 21 moves to the top of the intake pipe 7, the incoming gas enters the bottom of the partition seat 21 and passes through the partition. The bottom of the seat 21 cooperates with the ring seat 19 so that the filter cartridge 18 at the bottom performs dust removal and filtration on the flue gas first. The filtered gas moves upward inside the inner tank 17. When the bottom filter cartridge 18 is filtered for a long time, the filtration speed will be slow. The movable column 20 pushes the ring seat 19 down to move the partition seat 21 to the bottom of the air inlet position. The flue gas moves upward and passes through the filter cartridge 18 at the top of the partition seat 21 for filtration. When the filtration position is switched, the ring seat 19 and the partition seat 21 scrape the outer wall of the filter cartridge 18 to complete the dust cleaning. When the dust is cleaned, the inlet is closed. The fan 12 on the air pipe 7 and the dust exhaust pipe 11 works, and the fan 12 drives the dust to be discharged outward. After the dust-removed gas enters the desulfurization box 13 through the support pipe 10, the flue gas is sprayed into the desulfurization liquid through the air outlet 27. The desulfurization liquid removes the sulfur contained in the gas. When the gas moves in the desulfurization liquid, the driving motor 25 drives the stirring rod 26 to rotate, and the stirring rod 26 drives the bubbles to break. The broken gas is better in contact with the desulfurization liquid at different positions for rapid desulfurization. The pushing mechanism 35 drives the movable frame 32 to move up and down, and the movable frame 32 moves upward. When the movable frame 32 is moved, the liquid between the movable frame 32 and the support seat 28 is moved upward. The liquid moves upward to complete the reverse flushing of the surface of the filter plate 31 to avoid the clogging of the filter plate 31 by the dust in the flue gas. In addition, the up and down movement of the movable frame 32 controls the height of the liquid level. After the liquid level is adjusted, the time for the gas to move in the liquid is adjusted. Later, the movable frame 32 falls downward, and the liquid on the top of the filter plate 31 moves to both sides. The movement of the liquid to both sides drives the dust to fall on the movable frame 32. Finally, the movable frame 32 cooperates with the sewage pipe 14 to facilitate the discharge of waste liquid.
