Description

Technical Field

[0001] This utility model relates to the technical field of industrial waste gas purification devices, and in particular to a modular high-efficiency industrial waste gas purification device. Background Technology

[0002] The impact of waste gas emissions on the environment and human health during industrial production is receiving increasing attention. To effectively control pollutant emissions, industrial waste gas purification devices are widely used in various industrial enterprises. These devices are designed to treat waste gases generated during industrial production, ensuring they meet environmental emission standards.

[0003] Traditional high-efficiency industrial waste gas purification devices, due to the rigid connection between their modules, often require disassembly of the entire device or partial disassembly when internal malfunctions occur or regular maintenance is needed. This makes it difficult for workers to quickly disassemble, inspect, and clean the device, thus reducing the convenience of maintenance. Therefore, those skilled in the art have provided a modular high-efficiency industrial waste gas purification device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular and efficient industrial waste gas purification device. The device allows workers to easily rotate it at a certain angle, facilitating the inspection and cleaning of the spray box and filter box, and enabling the rapid disassembly of each module, thereby improving the convenience of maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular high-efficiency industrial waste gas purification device, comprising a particle removal box, a spray box, and a filter box. The spray box is located at the center of the upper end face of the particle removal box, and the filter box is located at the center of the upper end face of the spray box. An air outlet is provided at the upper port of the filter box, and a discharge port is provided at the lower port of the particle removal box. A drainage box is provided at the center of the lower end face of the discharge port. A baffle is provided at the upper end of the center of the particle removal box, and a cyclone dust collector is provided at the center of the lower end face of the baffle. A guide plate is provided at the lower end of the center of the spray box. An adjustment device is provided at the rear side of the center of the upper end face of the drainage box. Sealing and fixing devices are provided at the center of the upper end faces of both the particle removal box and the spray box.

[0006] The adjusting device includes a fixed column, which is located on the upper end face of the drainage tank. Three connecting columns are arranged vertically at the center of the outer side of the fixed column. Each of the three connecting columns has a connecting block on its outer side. One end of each of the three connecting blocks is fixedly connected to the outer side of the particle removal tank, the spray tank, and the filter tank, respectively. The two uppermost connecting columns are rotatably connected to the outer side of the fixed column through bearings.

[0007] The above technical solution uses bearings to rotatably connect the connecting columns to the outer sides of the fixed columns, which satisfies the rotation requirements of the spray box and the filter box. This allows the staff to rotate them at a certain angle, enabling the maintenance and cleaning of the inside of the spray box and the filter box, and achieving rapid disassembly of each module.

[0008] Furthermore, the particle removal box and the spray box are provided with a fixing block at the upper end of one side of the front face center and at the upper end of the front face center of one side. The two fixing blocks at the front are provided with a square groove at the rear end of the upper face center and the two fixing blocks at the side are provided with a square groove at the side end of the upper face center. The four square grooves are provided with a spring at the center of the lower inner wall. The upper ends of the four springs are fixedly connected to a limit block. The three limit blocks are slidably connected to the three square grooves respectively.

[0009] With the above technical solution, when the spray box and filter box need to be rotated and adjusted for maintenance, the limiting block is pressed to compress the spring, which is then fitted inside the square groove, thus satisfying the rotation requirements of the spray box and filter box and enabling quick disassembly, maintenance, and cleaning. When the spray box and filter box need to be returned to their original positions, the limiting block is pressed to rotate the spray box and filter box between the two limiting blocks, and then the spring rebounds to drive the limiting block to slide out of the square groove, thus satisfying the limiting and fixing of the spray box and filter box, thereby improving the convenience of maintenance.

[0010] Furthermore, the sealing and fixing device below includes a frame-shaped groove, which is located at the center of the upper end face of the particle removal box. Multiple miniature telescopic rods are arranged in a rectangular pattern at the center of the lower inner wall of the frame-shaped groove. Frame-shaped inserts are provided inside the frame-shaped groove at the output ends of the multiple miniature telescopic rods. A slot is provided at the center of the lower end face of the spray box. Sealing strips are provided at the center of the front and rear inner walls and the center of the two inner side walls of the slot. Inclined grooves are provided at the center of the lower end faces of the multiple sealing strips.

[0011] With the above technical solution, when the particle removal box and the spray box need to be connected for use, the miniature telescopic rod drives the frame-shaped insert to be inserted into the slot. The frame-shaped insert then squeezes the sealing strip, causing it to elastically deform and tightly adhere to the area around the frame-shaped insert, forming a reliable seal. This improves the sealing effect of the connection. Furthermore, the inclined groove allows the frame-shaped insert to be smoothly guided into the slot, avoiding any obstruction that could affect the sealing effect.

[0012] Furthermore, the upper end face of the frame-shaped insert has multiple circular grooves arranged in a rectangular pattern at the center, and each of the multiple circular grooves has a suction cup at the center. The lower end face of the frame-shaped insert has multiple miniature air pumps arranged in a rectangular pattern at the center, and the input ends of the multiple miniature air pumps are respectively connected to the multiple suction cups.

[0013] With the above technical solution, when the micro air pump is started, it draws air from the suction cup to create a negative pressure environment. The negative pressure causes the suction cup to adhere tightly to the inner wall of the slot, further enhancing the connection effect.

[0014] Furthermore, a cleaning device is provided at the center of the discharge port. The cleaning device includes a chute, which is located at the center of the front end face of the discharge port. A storage frame is slidably connected inside the chute. The rear end face of the storage frame is magnetically connected to the rear inner wall of the chute. A filter screen is provided at the lower end of the center of the storage frame.

[0015] The above technical solution uses a filter screen to block particulate matter and impurities removed by the particle removal box, and then stores them in a storage frame. The rear end of the storage frame is magnetically connected to the inner wall of the chute to prevent it from shifting or falling off and affecting the storage effect. The storage frame is also slidably connected to the chute, which makes it convenient for staff to quickly load, unload and clean the storage frame.

[0016] Furthermore, the cyclone dust collector's outlet pipe extends through the lower end face of the baffle to the upper end face of the baffle, and is correspondingly positioned with respect to the port of the guide plate;

[0017] The above technical solution involves connecting the exhaust pipe of the cyclone dust collector to the upper end of the baffle plate via the lower end of the baffle plate. This allows the centrifugal force of the exhaust gas in the cyclone dust collector to remove particulate matter from the exhaust gas. The exhaust gas after particulate matter removal is then transported to water via the exhaust pipe, and then transported to the spray box for further processing via the cyclone dust collector and the guide plate.

[0018] Furthermore, a water supply pipe is provided at the upper center of the spray box, and a mist nozzle is provided at the center of the lower end face of the water supply pipe. An activated carbon filter is provided at the center of the filter box. An exhaust gas inlet pipe is provided at the rear center of one side of the particle removal box. The exhaust gas inlet pipe passes through the particle removal box and the cyclone dust collector in sequence and leads to the interior of the cyclone dust collector. The output end is tangentially connected to the cyclone dust collector. A drain outlet is provided at the lower rear center of one side of the drainage box.

[0019] The above technical solution involves spraying the spray liquid delivered by the water pipe through a mist nozzle, forming a uniform spray area that allows for more thorough contact with the exhaust gas, thus improving the spray washing effect. An activated carbon filter then utilizes its adsorption properties to remove organic matter, odors, and other harmful substances from the exhaust gas, effectively adsorbing various pollutants. The exhaust gas inlet and outlet are tangentially connected to the cyclone dust collector, creating a strong rotational motion as the exhaust gas enters. This throws particulate matter against the cyclone dust collector wall, causing it to slide down to the discharge port for discharge. The spray liquid then flows from inside the cyclone dust collector, further flushing away particulate matter from the inner wall. Finally, the spray liquid is transported to the drainage tank through the discharge port and discharged through the drain outlet.

[0020] This utility model has the following beneficial effects:

[0021] In this utility model, when the modular high-efficiency industrial waste gas purification device is used, the connecting columns are rotatably connected to the outer side of the fixed columns via bearings, which satisfies the rotation requirements of the spray box and filter box. This facilitates the rotation of the spray box and filter box by the staff, allowing for easy inspection and cleaning of the interior of the spray box and filter box, and enabling quick disassembly of each module. Furthermore, by pressing the limiting block, the spring is compressed and fitted inside the square groove, satisfying the rotation requirements of the spray box and filter box, enabling quick disassembly, inspection, and cleaning. The spring rebound causes the limiting block to slide out of the square groove, satisfying the limiting and fixing of the spray box and filter box, thereby improving the convenience of maintenance.

[0022] In this invention, when the particle removal box and the spray box need to be connected, a miniature telescopic rod drives the frame-shaped insert to be inserted into the slot. The frame-shaped insert then squeezes the sealing strip, causing it to deform elastically and fit tightly around the frame-shaped insert, forming a reliable seal. This improves the sealing effect of the connection. A miniature air pump is then activated to extract air from the suction cup, creating a negative pressure environment. This negative pressure causes the suction cup to adhere tightly to the inner wall of the slot, further enhancing the connection effect. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-6This utility model provides an embodiment of a modular high-efficiency industrial waste gas purification device, comprising a particle removal chamber 1, a spray chamber 2, and a filter chamber 3. The spray chamber 2 is located at the center of the upper end face of the particle removal chamber 1, and the filter chamber 3 is located at the center of the upper end face of the spray chamber 2. An air outlet 4 is provided at the upper end of the filter chamber 3, and a discharge port 5 is provided at the lower end of the particle removal chamber 1. A drainage chamber 6 is located at the center of the lower end face of the discharge port 5. A baffle 7 is provided at the upper part of the center inside the particle removal chamber 1. A cyclone dust collector 8 is provided at the center of the lower end face of the baffle 7. A guide plate 9 is provided at the lower end of the center of the inside of the spray box 2. An adjustment device 13 is provided at the rear side of the center of the upper end face of the drainage box 6. A sealing and fixing device 14 is provided at the center of the upper end face of both the particle removal box 1 and the spray box 2. The adjustment device 13 allows the staff to rotate it at a certain angle, which meets the requirements for inspection and cleaning of the inside of the spray box 2 and the filter box 3, and realizes the quick disassembly of each module, thereby improving the convenience of maintenance.

[0033] The lower sealing and fixing device 14 includes a frame-shaped groove 1401, which is located at the center of the upper end face of the particle removal box 1. Multiple miniature telescopic rods 1402 are arranged in a rectangular pattern at the center of the lower inner wall of the frame-shaped groove 1401. Frame-shaped inserts 1403 are located inside the frame-shaped groove 1401 at the output ends of the multiple miniature telescopic rods 1402. A slot 1404 is located at the center of the lower end face of the spray box 2. Sealing strips 1405 are located at the center of the front and rear inner walls and the center of the two inner side walls of the slot 1404. The lower end faces of the multiple sealing strips 1405 are each provided with an inclined... When the particle removal chamber 1 and the spray chamber 2 need to be connected, the miniature telescopic rod 1402 drives the frame-shaped insert 1403 to be inserted into the slot 1404. The frame-shaped insert 1403 then compresses the sealing strip 1405, causing it to elastically deform and tightly adhere to the frame-shaped insert 1403, forming a reliable seal. This improves the sealing effect of the connection. The inclined groove 1406 then smoothly guides the frame-shaped insert 1403 into the slot 1404, preventing it from obstructing the sealing effect.

[0034] The upper surface of the frame-shaped insert 1403 has multiple circular grooves 1407 arranged in a rectangular pattern at the center. Each of the circular grooves 1407 has a suction cup 1408 at its center. The lower surface of the frame-shaped insert 1403 has multiple miniature air pumps 1409 arranged in a rectangular pattern at the center. The input ends of the multiple miniature air pumps 1409 are respectively connected to the multiple suction cups 1408. When the miniature air pumps 1409 are started, they draw air from the suction cups 1408 to create a negative pressure environment. The negative pressure causes the suction cups 1408 to adhere tightly to the inner wall of the slot 1404, further enhancing the connection effect.

[0035] A cleaning device 15 is provided at the center of the discharge port 5. The cleaning device 15 includes a chute 1501, which is located at the center of the front face of the discharge port 5. A storage frame 1502 is slidably connected inside the chute 1501. The rear end face of the storage frame 1502 is magnetically connected to the rear inner wall of the chute 1501. A filter screen 1503 is provided at the lower center of the storage frame 1502. The filter screen 1503 blocks the particles and impurities removed by the particle removal box 1 and stores them through the storage frame 1502. The magnetic connection between the rear end face of the storage frame 1502 and the rear inner wall of the chute 1501 prevents it from shifting and falling off, which would affect the storage effect. The slidable connection between the storage frame 1502 and the chute 1501 facilitates the quick loading, unloading, and cleaning of the storage frame 1502 by the staff.

[0036] The outlet pipe of the cyclone dust collector 8 passes through the lower end face of the baffle 7 and extends to the upper end face of the baffle 7, and is correspondingly set with the port of the guide plate 9. The centrifugal action of the outlet pipe of the cyclone dust collector 8 in the cyclone dust collector 8 removes particulate matter from the exhaust gas. The exhaust gas after the removal of particulate matter is then transported to water through the outlet pipe, and then transported to the spray box 2 for further processing by the cyclone dust collector 8 and the guide plate 9.

[0037] A water supply pipe 10 is located at the upper center of the spray chamber 2, and a mist nozzle 11 is located at the center of the lower end face of the water supply pipe 10. An activated carbon filter 12 is located at the center of the filter chamber 3. An exhaust gas inlet pipe 16 is located at the rear center of one side of the particle removal chamber 1. The exhaust gas inlet pipe 16 passes through the particle removal chamber 1 and the cyclone dust collector 8, and leads to the interior of the cyclone dust collector 8. The output end is tangentially connected to the cyclone dust collector 8. A drain outlet 17 is located at the lower rear center of one side of the drainage chamber 6. The spray liquid delivered by the water supply pipe 10 is sprayed through the mist nozzle 11 to form a uniform spray area, allowing it to contact the exhaust gas more fully and improve the spray washing effect. The activated carbon filter 12 utilizes the adsorption properties of activated carbon to remove organic matter, odors, and other harmful substances from the exhaust gas, effectively adsorbing various pollutants. The exhaust gas is then tangentially connected to the cyclone dust collector 8 through the exhaust gas inlet pipe 16. When the exhaust gas enters the cyclone dust collector 8, it generates a strong rotational motion, throwing the particulate matter in the exhaust gas against the wall of the cyclone dust collector 8 and allowing it to slide down the wall to the discharge port 5 for discharge. Then, a spray liquid is introduced from inside the cyclone dust collector 8 to help flush the particulate matter from the inner wall of the cyclone dust collector 8. The spray liquid is then transported to the drainage tank 6 through the discharge port 5 and finally discharged through the drain outlet 17.

[0038] like Figure 1 , 2As shown in Figure 3, the adjusting device 13 includes a fixed column 1301, which is located on the upper surface of the drainage tank 6. Three connecting columns 1302 are arranged vertically at the center of the outer side of the fixed column 1301. Each of the three connecting columns 1302 has a connecting block 1303 on its outer side. One end of each of the three connecting blocks 1303 is fixedly connected to the outer side of the particle removal tank 1, the spray tank 2, and the filter tank 3, respectively. The two upper connecting columns 1302 are rotatably connected to the outer side of the fixed column 1301 via bearings. This rotatable connection between the connecting columns 1302 and the outer side of the fixed column 1301 allows for the rotation of the spray tank 2 and the filter tank 3, facilitating the rotation of these components by operators. This enables the maintenance and cleaning of the interior of the spray tank 2 and the filter tank 3, and facilitates the rapid disassembly of each module.

[0039] Fixed blocks 1304 are provided at the upper part of one side of the front center of the particle removal chamber 1 and the upper part of the front center of one side of the spray chamber 2. Square grooves 1305 are provided at the rear part of the upper center of the upper end face of the two front fixed blocks 1304 and the side fixed blocks 1304 at the side part of the upper end face of the two side fixed blocks 1304. Springs 1306 are provided at the center of the lower inner wall of the four square grooves 1305. Limiting blocks 1307 are fixedly connected to the upper ends of the four springs 1306. The three limiting blocks 1307 are slidably connected to the three square grooves 1305 respectively. When it is necessary to rotate and adjust the spray chamber 2 and the filter chamber 3 for maintenance, By pressing the limiting block 1307, the spring 1306 is compressed and fitted inside the square groove 1305, thus satisfying the rotation requirements of the spray box 2 and the filter box 3, enabling quick disassembly, maintenance, and cleaning. When the spray box 2 and the filter box 3 need to be returned to their original positions, pressing the limiting block 1307 rotates the spray box 2 and the filter box 3 between the two limiting blocks 1307. Then, the spring 1306 rebounds, causing the limiting block 1307 to slide out of the square groove 1305, thus satisfying the limiting and fixing of the spray box 2 and the filter box 3, thereby improving the convenience of maintenance.

[0040] Working principle: When using the modular high-efficiency industrial waste gas purification device, if the spray box 2 and filter box 3 need to be rotated for adjustment and maintenance, the limiting block 1307 is pressed to compress the spring 1306, which is then fitted inside the square groove 1305. The connecting column 1302 is then rotatably connected to the outside of the fixed column 1301 via bearings, thus satisfying the rotation requirements of the spray box 2 and filter box 3 and enabling quick disassembly, maintenance, and cleaning. When the spray box 2 and filter box 3 need to be returned to their original positions, the limiting block 1307 is pressed to rotate the spray box 2 and filter box 3 between the two limiting blocks 1307. The spring 1306 then rebounds, causing the limiting block 1307 to slide out of the square groove 1305, thus satisfying the limiting and fixing of the spray box 2 and filter box 3, thereby improving the convenience of maintenance.

[0041] When the particle removal chamber 1 and the spray chamber 2 need to be connected, the miniature telescopic rod 1402 drives the frame-shaped insert 1403 to be inserted into the slot 1404. The frame-shaped insert 1403 then squeezes the sealing strip 1405, causing it to elastically deform and tightly adhere to the frame-shaped insert 1403, forming a reliable seal and improving the sealing effect of the connection. The inclined groove 1406 then smoothly guides the frame-shaped insert 1403 into the slot 1404, avoiding any obstruction that could affect the sealing effect. When the miniature air pump 1409 is started, it draws air from the suction cup 1408, creating a negative pressure environment. This negative pressure causes the suction cup 1408 to tightly adhere to the inner wall of the slot 1404, further enhancing the connection effect.

[0042] The exhaust gas is tangentially connected to the cyclone dust collector 8 through the exhaust gas inlet pipe 16. When the exhaust gas enters the cyclone dust collector 8, it can form a strong rotational motion, which throws the particulate matter in the exhaust gas toward the wall of the cyclone dust collector 8 and slides down the wall to the discharge port 5 for discharge. Then, the particulate matter and impurities removed by the particle removal box 1 are blocked by the filter screen 1503. Then, the particulate matter and impurities are stored in the storage frame 1502. The rear end face of the storage frame 1502 is magnetically connected to the inner wall of the slide 1501 to prevent abnormal movement and falling off, which would affect the storage effect. The storage frame 1502 is slidably connected to the slide 1501, which makes it convenient for the staff to quickly load, unload and clean the storage frame 1502.

[0043] The exhaust pipe of the cyclone dust collector 8 passes through the lower end face of the baffle 7 and extends to the upper end face of the baffle 7, thus satisfying the centrifugal effect of the exhaust gas in the cyclone dust collector 8 to remove particulate matter. The exhaust gas after particulate matter removal is then transported to water through the exhaust pipe, and then through the cyclone dust collector 8 and the guide plate 9 to transport the exhaust gas to the spray box 2 for further treatment. Finally, the spraying liquid transported by the water pipe 10 is sprayed through the mist nozzle 11 to form a uniform spray area, allowing for more thorough spraying. The spraying process involves contacting the waste gas with a separate outlet to enhance the washing effect. The activated carbon filter 12 then uses its adsorption properties to remove organic matter, odors, and other harmful substances from the waste gas, effectively adsorbing various pollutants. The treated waste gas is then discharged through the outlet 4. The sprayed liquid then flows from inside the cyclone dust collector 8, helping to flush away particles from the inner wall of the cyclone dust collector 8. Finally, the sprayed liquid is transported to the drainage tank 6 through the discharge port 5 and discharged through the drain port 17.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
