Description

Technical Field

[0001] The present invention relates to the technical field of high-efficiency activated carbon waste gas treatment, in particular to a waste gas treatment device that is easy to replace. Background Art

[0002] A scrubber is a device used for gas absorption and purification. It is often used in exhaust gas treatment and environmental protection in industrial production processes. Its main function is to use liquid absorbents (such as water, alkali solution or other chemical solutions) to chemically react or physically absorb 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 scrubber to enhance the gas purification effect.

[0003] Because the adsorption effect of the high-efficiency activated carbon in the washing tower will decrease after long-term use, in order to ensure the adsorption effect of the high-efficiency activated carbon, the filler in the high-efficiency activated carbon needs to be replaced regularly.

[0016] The application provides a waste gas treatment device convenient to replace, and has the following beneficial effects: 1. After the water body carrying particulate matter gathers in the present invention, it can flow back to the base box through the return port and the return pipe at the bottom of the tower body for collection. The motor can drive the reciprocating screw to rotate through the first transmission belt, and the reciprocating screw can drive the sliding plate to move back and forth inside the base box during the rotation. The bottom end of the base box is inclined, and the sliding plate can move the scraper through the reset spring to make the scraper always fit with the bottom end of the base box. Through this design, after the water body carrying particulate matter gathers inside the base box, it can be returned to the base box through the water body's own sedimentation. The scraping of the sediment and scraper can collect the particulate matter in the exhaust gas at the lower right end of the base box, and this operation can effectively separate the water in the base box from the carried particulate matter. After the amount of water collected in the base box increases, by opening the valve at the recovery water pipe, the water pump can be used to wash the exhaust gas through the water in the base box. Because the recovery water pipe is located at a higher point inside the base box, this can effectively avoid the recovery water pipe 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.

[0017] 2. When the exhaust fan of the present invention rotates, it can generate an airflow flowing toward the exhaust pipe, and the airflow can be transmitted to the bottom end of the tower body through the opening at the loading box, so that the washed exhaust gas can be attracted by the airflow and enter the interior of the loading box. The feed fan can input the high-efficiency activated carbon into the interior of the loading box, so that the exhaust gas can fully contact with the high-efficiency activated carbon when passing through the interior of the loading box and then be discharged from the exhaust pipe. Because the synchronous rotating shaft can also drive the flipping paddle to rotate, and the flipping paddle is located inside the loading box, through this design, the flipping paddle can fully stir the high-efficiency activated carbon, so that the high-efficiency activated carbon can be fully utilized. In addition, because the flipping paddle rotates faster and drives the high-efficiency activated carbon to rotate, when the equipment is in use, only a small amount of high-efficiency activated carbon needs to be put into the loading box to fully contact with the exhaust gas, which can avoid the 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. In addition, thanks to the use of the flipping paddle, when the high-efficiency activated carbon needs to be replaced, the high-efficiency activated carbon in the loading box can be quickly discharged through the ventilation pipe through the exhaust fan and the stirring of the flipping paddle, which can avoid tedious manual replacement.

[0018] 3. The motor of the present invention can simultaneously drive the first transmission belt and the first bevel gear to rotate during the rotation process, which enables the equipment to automatically realize the recycling of wastewater and the mixing of high-efficiency activated carbon during the normal treatment of exhaust 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 recycling of wastewater and the mixing of high-efficiency activated carbon can 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 and highly integrates the functions, which can effectively reduce the production and maintenance costs of the equipment.

The outer end of the reciprocating screw rod 803 is provided with a sliding plate 804. The interior of the sliding plate 804 is embedded with a return spring 805. The return spring The bottom end of 805 is connected with a scraper 806, and the output end of the motor 801 is provided with a first bevel gear 807.

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 with the left side higher and the right side lower. The interior of the tower body 2 is provided with a loading box 11 for loading high-efficiency activated carbon, and the top outer side of the tower body 2 is connected with Exhaust pipe 12, the tower body 2 is located on both sides of the loading box 11 and is connected with a ventilation pipe 13, the outer end of the ventilation pipe 13 on the left side of the tower body 2 is connected to the feeding fan 14, and the outer end of the ventilation pipe 13 on the right side of the tower body 2 is connected to the discharging fan 15, the outer end of the tower body 2 is connected to the auxiliary through-pipe 16, the ventilation pipe 13 is connected to the interior of the loading box 11, and the auxiliary through-pipe 16 is connected to the interior of the loading box 11, and the flipping paddle 1006 extends into the interior of the loading box 11, and the flipping paddle 1006 and the exhaust fan 1005 rotate synchronously with the rotation of the synchronous rotating shaft 1004; The specific operation is as follows: industrial waste gas can enter the interior of the tower body 2 through the air inlet 3. After the waste gas enters the interior of the tower body 2, the water inlet pipe 402 works to input clean water from the outside of the equipment into the interior of the water pump 401. The water pump 401 works to transmit the water body to the interior of the boosting pipe 404. After the water body is pressurized inside the boosting pipe 404, it can be sprayed out in the form of mist through the interior of the spray plate seat 405 to contact the industrial waste gas. After the mist water contacts the industrial waste gas, it can effectively contact the particulate matter in the industrial waste gas to separate the particulate matter from the gas. After the water body carrying the particulate matter gathers, it can flow back to the interior of the base box 1 through the return sewage port 6 and the return sewage pipe 7 at the bottom of the tower body 2 for collection. The motor 801 works to drive the reciprocating screw rod 8 through the first transmission belt 802 03 rotates, and the reciprocating screw 803 can drive the sliding plate 804 to move back and forth inside the base box 1 during the rotation process. The bottom end of the base box 1 is inclined, and the sliding plate 804 displaces the scraper 806 through the return spring 805, so 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 gathers 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, and 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. At this time, the water pump 401 works to remove the exhaust gas through the water in the base box 1. Washing, because the recycling water pipe 403 is located at a higher position 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. The motor 801 drives the first transmission belt 802 to rotate and can also drive the second bevel gear 1001 to rotate through the first bevel gear 807. During the rotation of the second bevel gear 1001, the second transmission belt 1003 can be driven to rotate through the driven shaft 1002, and the second transmission belt 1003 can drive the exhaust fan 1005 and the flip paddle 1006 to rotate through the synchronous shaft 1004. When the exhaust fan 1005 rotates, it can generate an airflow flowing to the exhaust pipe 12, and the airflow can be transmitted to the tower body 2 through the opening at the loading box 11. The bottom end of the loading box 11 allows the washed exhaust gas to be attracted by the airflow and enter the interior of the loading box 11. The feed fan 14 can input the high-efficiency activated carbon into the interior of the loading box 11, which allows the exhaust gas to fully contact with the high-efficiency activated carbon when passing through the interior of the loading box 11 and then be discharged from the exhaust pipe 12. The synchronous rotating shaft 1004 can also drive the flipping paddle 1006 to rotate, and the flipping paddle 1006 is located inside the loading box 11. Through this design, the flipping paddle 1006 can fully stir the high-efficiency activated carbon, so that the high-efficiency activated carbon can be fully used. In addition, because the flipping paddle 1006 rotates at a faster speed and drives the high-efficiency activated carbon to rotate, when the equipment is in use, only a small amount of high-efficiency activated carbon needs to be put into the loading box 11 to fully contact with the exhaust gas.This can avoid filling too much high-efficiency activated carbon to cause waste and poor air flow, and the use of auxiliary pipe 16 can further alleviate the problem of poor air flow. In addition, thanks to the use of the turning paddle 1006, when it is necessary to replace the high-efficiency activated carbon, the high-efficiency activated carbon in the loading box 11 can be quickly discharged through the air outlet fan 15 and the stirring of the turning paddle 1006. This can avoid the tedious manual replacement. Because the motor 801 can simultaneously drive the first transmission belt 802 and the first bevel gear 807 to rotate during rotation, the device can automatically realize the recycling of wastewater and the mixing of high-efficiency activated carbon during normal treatment of exhaust gas. The above functions are driven by a single drive source, which can improve the functionality of the device while ensuring the simplicity of the device operation. In addition, the steps of recycling wastewater and mixing high-efficiency activated carbon can correspond to the cleaning of the sediment and the replacement of the high-efficiency activated carbon in the cleaning process, which makes the operation of the device simple and highly integrated, effectively reducing the production and maintenance cost of the device.

[0023] In summary, the waste gas treatment device is convenient to replace. When in use, industrial waste gas can enter the inside of the tower body 2 through the gas inlet 3. After the waste gas enters the inside of the tower body 2, the water inlet pipe 402 works to input clean water outside the device into the water pump 401. The water pump 401 works to transmit the water to the booster pipe 404. After the water is pressurized in the booster pipe 404, it is sprayed in a mist state through the inside of the spray plate seat 405 to contact the industrial waste gas. After the mist water contacts the industrial waste gas, it can effectively contact the particulate matter in the industrial waste gas to separate the particulate matter from the gas. After the water carrying the particulate matter is collected, it can flow back to the base box 1 inside through the back pollution port 6 and the back pollution pipe 7 at the bottom of the tower body 2 for collection. Then the motor 801 works to drive the reciprocating screw rod 803 through the first transmission belt 802. During rotation, the reciprocating screw rod 803 can drive the sliding plate 804 to reciprocate in the base box 1. The bottom of the base box 1 is inclined. The displacement of the scraper 806 by the return spring 805 makes the scraper 806 always fit the bottom of the base box 1. Through this design, after the water carrying the particulate matter is collected in the base box 1, the particulate matter in the waste gas can be collected at the right lower 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 particulate matter. After the water collection amount in the base box 1 increases, the valve at the recovery water pipe 403 is opened. At this time, the water pump 401 works to wash the waste gas with the water in the base box 1. Because the recovery water pipe 403 is located at a high position in the base box 1, this can effectively avoid the recovery water pipe 403 from sucking back the particulate matter. Through this design, the device can realize the recycling of water, which can improve the environmental performance of the device. Then, the motor 801 drives the first transmission belt 802 to rotate, and at the same time drives the second transmission belt 1001 to rotate through the first bevel gear 807. During the rotation of the second bevel gear 1001, the second transmission belt 1003 can be driven to rotate through the driven shaft 1002, and the second transmission belt 1003 can drive the exhaust fan 1005 and the flip paddle 1006 to rotate through the synchronous shaft 1004. When the exhaust fan 1005 rotates, it can generate an air flow flowing toward the exhaust pipe 12, and the air flow can be transmitted to the bottom end of the tower body 2 through the opening at the loading box 11, which allows the washed exhaust gas to enter the interior of the loading box 11 through the suction of the air flow, and the feed fan 14 can input the high-efficiency activated carbon into the interior of the loading box 11, which makes the exhaust gas When the air passes through the interior of the loading box 11, it can fully contact with the high-efficiency activated carbon and then be discharged from the exhaust pipe 12. Because the synchronous rotating shaft 1004 can also drive the flipping paddle 1006 to rotate, and the flipping paddle 1006 is located inside the loading box 11, through this design, the flipping paddle 1006 can fully stir the high-efficiency activated carbon, so that the high-efficiency activated carbon can be fully used. In addition, because the flipping paddle 1006 rotates at a high speed and drives the high-efficiency activated carbon to rotate, when the equipment is in use, only a small amount of high-efficiency activated carbon needs to be put into the loading box 11 for it to fully contact with the exhaust gas. This can avoid the waste caused by filling too much high-efficiency activated carbon and the poor air circulation. In addition, the use of the auxiliary through-tube 16 can further alleviate the problem of poor air circulation. Finally, when the equipment needs to replace the high-efficiency activated carbon, the high-efficiency activated carbon in the loading box 11 can be quickly discharged through the ventilation pipe 13 through the exhaust fan 15 and the stirring of the flipping paddle 1006, which can avoid 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 process, 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 recycling of wastewater and the mixing of high-efficiency activated carbon can 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 and highly integrates the functions, which can effectively reduce the production and maintenance costs of the equipment.
