Description

Technical Field

[0001] This invention relates to the field of high-efficiency activated carbon waste gas treatment technology, specifically to a waste gas treatment device that is easy to replace. Background Technology

[0002] A scrubbing tower is a device used for gas absorption and purification. It is commonly used for exhaust gas treatment and environmental protection in industrial production processes. Its main function is to use liquid absorbents (such as water, alkaline solutions or other chemical solutions) to react chemically or physically with pollutants in the gas, thereby achieving the purpose of purifying the gas. In order to improve the gas purification effect, high-efficiency activated carbon is usually added to the scrubbing tower to enhance the gas purification effect.

[0003] Because the adsorption effect of the high-efficiency activated carbon in the scrubbing tower will decrease after long-term use, it is necessary to replace the packing material inside the high-efficiency activated carbon regularly in order to ensure the adsorption effect of the high-efficiency activated carbon. Since the scrubbing tower is large in size and height and contains a large number of high-efficiency activated carbon, manual replacement is required for effective replacement. However, manual operation has disadvantages such as long time consumption and high risk.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an easily replaceable waste gas treatment device. Summary of the Invention

[0005] The purpose of this invention is to provide an easily replaceable waste gas treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an easily replaceable waste gas treatment device, comprising a base box, a tower body, and an airflow control assembly. The tower body is mounted on the outer top of the base box, and an air inlet is provided on the lower front side of the tower body. A spray assembly is provided on the inner bottom side of the tower body. A partition is provided inside the base box, and a sludge return port is provided on the top of the base box. A sludge return pipe is connected to the bottom end of the sludge return port. A cleaning assembly is connected to the outer end of the tower body. A sludge discharge port is provided on the outer end of the base box. An airflow control assembly is provided on the outer end of the base box. The airflow control assembly includes a second conical tooth, a driven rotating shaft, a second transmission belt, a synchronous rotating shaft, an exhaust fan, and a tumbling paddle. The driven rotating shaft is connected to the outer top of the second conical tooth, and the driven rotating shaft is connected to the synchronous rotating shaft through the second transmission belt. An exhaust fan is connected to the top of the synchronous rotating shaft, and a tumbling paddle is provided at the bottom end of the synchronous rotating shaft.

[0007] Furthermore, the spray assembly includes a water pump, an inlet pipe, a return water pipe, a booster pipe, and a spray plate seat. The left outer end of the water pump is connected to the inlet pipe, and the right outer end of the water pump is connected to the return water pipe. The top outer side of the water pump is connected to the booster pipe, and the outer end of the booster pipe is provided with a spray plate seat.

[0008] Furthermore, the water pump is located in the compartment between the base box and the partition, and the water recovery pipe extends through the partition into the interior of the base box.

[0009] Furthermore, the wastewater return port is connected to the wastewater return pipe, and the wastewater return pipe passes through the partition and is connected to the base box.

[0010] Furthermore, the cleaning assembly includes a motor, a first transmission belt, a reciprocating lead screw, a sliding plate, a return spring, a scraper, and a first bevel gear. The output end of the motor is provided with a first transmission belt, and the bottom end of the first transmission belt is connected to a reciprocating lead screw. The outer end of the reciprocating lead screw is provided with a sliding plate, and a return spring is embedded inside the sliding plate. The bottom end of the return spring is connected to a scraper, and the output end of the motor is provided with a first bevel gear.

[0011] Furthermore, the motor drives the driven shaft to rotate through the meshing of the first bevel teeth and the second bevel teeth, and the motor drives the reciprocating screw to rotate through the first transmission belt.

[0012] Furthermore, the lower surface of the scraper is in contact with the bottom surface of the base box, and the bottom surface of the base box is inclined with the left side higher than the right side.

[0013] Furthermore, the tower body is equipped with a loading box for loading high-efficiency activated carbon inside, and an exhaust pipe is connected to the outer top of the tower body. Ventilation pipes are connected to both sides of the tower body located at the loading box. A feed fan is connected to the outer end of the ventilation pipe on the left side of the tower body, and a discharge fan is connected to the outer end of the ventilation pipe on the right side of the tower body. An auxiliary pipe is connected to the outer end of the tower body.

[0014] Furthermore, the vent pipe is connected to the interior of the loading box, and the auxiliary vent pipe is also connected to the interior of the loading box.

[0015] Furthermore, the tumbling paddle extends into the loading box, and the tumbling paddle and the exhaust fan rotate synchronously with the rotation of the synchronous shaft.

[0016] This invention provides an easily replaceable waste gas treatment device, which has the following advantages:

[0017] 1. In this invention, water carrying particulate matter, after being collected, can flow back to the base box at the bottom of the tower body through the return port and return pipe for collection. The motor drives a reciprocating screw via a first transmission belt. During rotation, the reciprocating screw moves a sliding plate back and forth inside the base box. The bottom of the base box is inclined, and the sliding plate, via a return spring, ensures the scraper remains in contact with the bottom of the base box. Through this design, water carrying particulate matter, after being collected inside the base box, settles due to sedimentation. The scraping action of the sediment and scraper allows particulate matter in the exhaust gas to be collected at the lower right end of the base box. This operation effectively separates the water in the base box from the carried particulate matter. As the amount of water collected in the base box increases, the valve at the recycling water pipe is opened, and the water pump operates to wash the exhaust gas using the water in the base box. Because the recycling water pipe is located at a higher point inside the base box, it effectively prevents the recycling water pipe from sucking back particulate matter. This design enables the equipment to recycle water, which improves the environmental performance of the equipment.

[0018] 2. When the exhaust fan of this invention rotates, it generates an airflow that flows towards the exhaust pipe. This airflow is transmitted to the bottom of the tower body through the opening at the loading box. This allows the washed exhaust gas to be drawn into the interior of the loading box by the airflow. The feed fan then feeds high-efficiency activated carbon into the loading box. This ensures that the exhaust gas, as it passes through the loading box, makes full contact with the high-efficiency activated carbon before being discharged from the exhaust pipe. Furthermore, the synchronous rotating shaft also drives the agitator paddle to rotate. Since the agitator paddle is located inside the loading box, this design allows the agitator paddle to fully agitate the high-efficiency activated carbon, ensuring that the high-efficiency activated carbon is fully utilized. Furthermore, because the rotating paddle rotates at a high speed and drives the high-efficiency activated carbon to rotate, only a small amount of high-efficiency activated carbon needs to be put into the loading box during use to ensure sufficient contact with the exhaust gas. This avoids waste caused by filling too much high-efficiency activated carbon and poor air circulation. In addition, the use of auxiliary ventilation pipes can further alleviate the problem of poor air circulation. Moreover, thanks to the use of the rotating paddle, when it is necessary to replace the high-efficiency activated carbon, the high-efficiency activated carbon in the loading box can be quickly discharged through the ventilation pipe by the exhaust fan combined with the stirring of the rotating paddle, which can eliminate the need for tedious manual replacement.

[0019] 3. During the rotation of the motor of this invention, the first transmission belt and the first bevel gear can be driven to rotate simultaneously. This enables the equipment to automatically realize the recycling of wastewater and the mixing of high-efficiency activated carbon during the normal treatment of waste gas. The above functions are driven by a single drive source, which can improve the functionality of the equipment while ensuring the simplicity of equipment operation. In addition, the steps of recycling wastewater and mixing high-efficiency activated carbon can correspond to the cleaning of precipitates and the replacement of high-efficiency activated carbon in the cleaning process. This simplifies the operation of the equipment, and the high integration of functions can effectively reduce the production and maintenance costs of the equipment. Attached Figure Description

[0028] Please see Figures 1 to 7The present invention provides a technical solution: an easily replaceable waste gas treatment device, comprising a base box 1, a tower body 2, and an airflow control assembly 10. The tower body 2 is mounted on the outer top of the base box 1, and an air inlet 3 is provided on the lower front side of the tower body 2. A spray assembly 4 is provided on the inner bottom side of the tower body 2. A partition 5 is provided inside the base box 1, and a wastewater return port 6 is provided on the top of the base box 1. A wastewater return pipe 7 is connected to the bottom end of the wastewater return port 6. A cleaning assembly 8 is connected to the outer end of the tower body 2, and a wastewater discharge port 9 is provided on the outer end of the base box 1. An airflow control component 10 is provided, which includes a second bevel gear 1001, a driven shaft 1002, a second transmission belt 1003, a synchronous shaft 1004, an exhaust fan 1005, and an agitator 1006. The driven shaft 1002 is connected to the outer top of the second bevel gear 1001, and the driven shaft 1002 is connected to the synchronous shaft 1004 through the second transmission belt 1003. The exhaust fan 1005 is connected to the top of the synchronous shaft 1004, and the agitator 1006 is provided at the bottom of the synchronous shaft 1004.

[0029] Please see Figures 1 to 7The spray assembly 4 includes a water pump 401, an inlet pipe 402, a return water pipe 403, a booster pipe 404, and a spray plate seat 405. The left outer end of the water pump 401 is connected to the inlet pipe 402, and the right outer end of the water pump 401 is connected to the return water pipe 403. The top outer side of the water pump 401 is connected to the booster pipe 404, and the outer end of the booster pipe 404 is provided with the spray plate seat 405. The water pump 401 is located in the compartment between the base box 1 and the partition 5, and the return water pipe 403 extends through the partition 5 into the interior of the base box 1. The waste outlet 6 is connected to the return waste pipe 7, and the return waste pipe 7 passes through the partition 5 and is connected to the base box 1. The cleaning component 8 includes a motor 801, a first transmission belt 802, a reciprocating screw 803, a sliding plate 804, a return spring 805, a scraper 806, and a first bevel gear 807. The output end of the motor 801 is provided with the first transmission belt 802, and the bottom end of the first transmission belt 802 is connected to the reciprocating screw 803. The outer end of the reciprocating screw 803 is provided with the sliding plate 804, and the return spring 805 is embedded inside the sliding plate 804. A scraper 806 is connected to the bottom end of 805. A first bevel gear 807 is provided at the output end of motor 801. Motor 801 drives the driven shaft 1002 to rotate through the meshing of the first bevel gear 807 and the second bevel gear 1001. Motor 801 also drives the reciprocating screw 803 to rotate through the first transmission belt 802. The lower surface of the scraper 806 is in contact with the bottom surface of the base box 1, and the bottom surface of the base box 1 is inclined from left to right. A loading box 11 for loading high-efficiency activated carbon is installed inside the tower body 2, and the top outer side of the tower body 2 is connected to... The tower body 2 is connected to the two sides of the loading box 11 by the exhaust pipe 12 and the ventilation pipe 13. The outer end of the ventilation pipe 13 on the left side of the tower body 2 is connected to the feed fan 14, and the outer end of the ventilation pipe 13 on the right side of the tower body 2 is connected to the discharge fan 15. The outer end of the tower body 2 is connected to the auxiliary pipe 16. The ventilation pipe 13 is connected to the inside of the loading box 11, and the auxiliary pipe 16 is connected to the inside of the loading box 11. The tumbling paddle 1006 extends into the inside of the loading box 11, and the tumbling paddle 1006 and the exhaust fan 1005 rotate synchronously with the rotation of the synchronous shaft 1004.

[0030] The specific operation is as follows: Industrial waste gas enters the interior of tower body 2 through inlet 3. After the waste gas enters the interior of tower body 2, water inlet pipe 402 operates, inputting clean water from outside the equipment into water pump 401. Water pump 401 operates, transmitting water to booster pipe 404. After being pressurized inside booster pipe 404, the water is sprayed out in mist form through spray plate seat 405, contacting the industrial waste gas. The mist water effectively contacts the particulate matter in the industrial waste gas, separating the particulate matter from the gas. The water carrying the particulate matter accumulates and flows back to base box 1 at the bottom of tower body 2 through return port 6 and return pipe 7 for collection. Motor 801 operates, driving reciprocating screw 8 through first transmission belt 802. 03 rotates, and during the rotation of the reciprocating screw 803, it drives the sliding plate 804 to move back and forth inside the base box 1. The bottom end of the base box 1 is inclined. The sliding plate 804, through the return spring 805, causes the scraper 806 to move, ensuring that the scraper 806 is always in contact with the bottom end of the base box 1. Through this design, after the water carrying particulate matter accumulates inside the base box 1, the particulate matter in the exhaust gas can be collected at the lower right end of the base box 1 through the sedimentation of the water itself and the scraping of the scraper 806. This operation can effectively separate the water in the base box 1 from the carried particulate matter. After the amount of water collected in the base box 1 increases, the valve at the recovery water pipe 403 is opened, and the water pump 401 works to remove the exhaust gas through the water in the base box 1. The washing process is facilitated by the recycling water pipe 403 being located at a higher position inside the base box 1, effectively preventing the pipe from sucking back particulate matter. This design enables the equipment to recycle water, improving its environmental performance. Simultaneously, the motor 801 drives the first transmission belt 802 to rotate, and also drives the second bevel gear 1001 to rotate via the first bevel gear 807. During the rotation of the second bevel gear 1001, the driven shaft 1002 drives the second transmission belt 1003 to rotate. The second transmission belt 1003, in turn, drives the exhaust fan 1005 and the agitator 1006 to rotate via the synchronous shaft 1004. The rotation of the exhaust fan 1005 generates airflow towards the exhaust pipe 12, which is then transmitted to the tower body 2 through the opening at the loading box 11. The bottom of the loading box 11 allows the washed exhaust gas to be drawn into the interior of the loading box 11 by the airflow. The feed fan 14 feeds the high-efficiency activated carbon into the loading box 11, ensuring that the exhaust gas can fully contact the high-efficiency activated carbon as it passes through the loading box 11 before being discharged from the exhaust pipe 12. The synchronous rotating shaft 1004 also drives the agitator 1006 to rotate. Since the agitator 1006 is located inside the loading box 11, this design allows the agitator 1006 to fully agitate the high-efficiency activated carbon, ensuring its full utilization. Furthermore, because the agitator 1006 rotates at a relatively high speed and drives the high-efficiency activated carbon to rotate, only a small amount of high-efficiency activated carbon needs to be added to the loading box 11 during operation to ensure sufficient contact with the exhaust gas.This avoids waste caused by overfilling with high-efficiency activated carbon and poor air circulation. Furthermore, the use of auxiliary pipe 16 further alleviates the problem of poor air circulation. Thanks to the use of the agitator 1006, when high-efficiency activated carbon needs to be replaced, the discharge fan 15, combined with the agitation of the agitator 1006, allows the high-efficiency activated carbon in the loading box 11 to be quickly discharged through the vent pipe 13, eliminating the need for tedious manual replacement. Because the motor 801 simultaneously drives the first transmission belt 802 and the first bevel gear 807 during rotation, the equipment automatically achieves wastewater recycling and high-efficiency activated carbon mixing during normal waste gas treatment. All of these functions are driven by a single drive source, which enhances the equipment's functionality while ensuring ease of operation. In addition, the wastewater recycling and high-efficiency activated carbon mixing steps correspond to the cleaning of sediment and replacement of high-efficiency activated carbon in the cleaning process, simplifying equipment operation. This high degree of functional integration effectively reduces the equipment's production and maintenance costs.

[0031] In summary, this easy-to-replace waste gas treatment device allows industrial waste gas to enter the tower body 2 through the inlet 3. After the waste gas enters the tower body 2, the water inlet pipe 402 operates, drawing clean water from outside the equipment into the water pump 401. The water pump 401 then transports the water to the booster pipe 404. After being pressurized in the booster pipe 404, the water is sprayed out in a mist form through the spray plate seat 405 to contact the industrial waste gas. The mist effectively contacts the particulate matter in the industrial waste gas, separating the particulate matter from the gas. The water carrying the particulate matter accumulates and flows back to the base box 1 at the bottom of the tower body 2 through the return port 6 and the return pipe 7 for collection.

[0032] Then, the motor 801 drives the reciprocating screw 803 to rotate via the first transmission belt 802. During the rotation of the reciprocating screw 803, it drives the sliding plate 804 to move back and forth inside the base box 1. The bottom of the base box 1 is inclined. The sliding plate 804, through the return spring 805, causes the scraper 806 to move, ensuring that the scraper 806 is always in contact with the bottom of the base box 1. Through this design, the water carrying particulate matter accumulates inside the base box 1. Through the sedimentation of the water itself and the scraping action of the scraper 806, the particulate matter in the exhaust gas can be removed. The particulate matter is collected at the lower right end of the base box 1. This operation can effectively separate the water in the base box 1 from the carried particulate matter. After the water volume in the base box 1 increases, the valve at the recycling water pipe 403 is opened. At this time, the water pump 401 works to wash the exhaust gas through the water in the base box 1. Since the recycling water pipe 403 is located at a high point inside the base box 1, this can effectively prevent the recycling water pipe 403 from sucking back particulate matter. Through this design, the equipment can realize the recycling of water, which can improve the environmental performance of the equipment.

[0033] Then, while the motor 801 drives the first transmission belt 802 to rotate, it can also drive the second bevel gear 1001 to rotate via the first bevel gear 807. During the rotation of the second bevel gear 1001, it can drive the second transmission belt 1003 to rotate via the driven shaft 1002. The second transmission belt 1003 can drive the exhaust fan 1005 and the agitator 1006 to rotate via the synchronous shaft 1004. When the exhaust fan 1005 rotates, it can generate airflow towards the exhaust pipe 12. The airflow can be transmitted to the bottom of the tower body 2 through the opening at the loading box 11. This allows the washed waste gas to be drawn into the interior of the loading box 11 by the airflow. The operation of the feed fan 14 can input high-efficiency activated carbon into the interior of the loading box 11, which allows the waste gas to be drawn into the interior of the tower body 2 through the opening at the loading box 11. When the gas passes through the loading box 11, it can fully contact the high-efficiency activated carbon before being discharged from the exhaust pipe 12. Because the synchronous rotating shaft 1004 can also drive the agitator 1006 to rotate, and the agitator 1006 is located inside the loading box 11, this design allows the agitator 1006 to fully stir the high-efficiency activated carbon, so that the high-efficiency activated carbon can be fully utilized. In addition, because the agitator 1006 rotates at a relatively fast speed and drives the high-efficiency activated carbon to rotate, only a small amount of high-efficiency activated carbon needs to be put into the loading box 11 during use to fully contact the exhaust gas. This avoids waste caused by filling too much high-efficiency activated carbon and poor air circulation. In addition, the use of the auxiliary pipe 16 can further alleviate the problem of poor air circulation.

[0034] Finally, when the equipment needs to replace the high-efficiency activated carbon, the discharge fan 15, combined with the agitation of the tumbling paddle 1006, allows the high-efficiency activated carbon in the loading box 11 to be quickly discharged through the vent pipe 13. This eliminates the need for tedious manual replacement. Because the motor 801 can simultaneously drive the first transmission belt 802 and the first bevel gear 807 to rotate during the rotation of the motor, the equipment can automatically achieve wastewater recycling and high-efficiency activated carbon mixing during normal waste gas treatment. All of the above functions are driven by a single drive source, which improves the functionality of the equipment while ensuring its ease of operation. In addition, the wastewater recycling and high-efficiency activated carbon mixing steps correspond to the cleaning of sediment and the replacement of high-efficiency activated carbon in the cleaning process, which simplifies the operation of the equipment. The high integration of functions can effectively reduce the production and maintenance costs of the equipment.
