Description

Technical Field

[0001] This utility model relates to the field of air pollution control technology, and in particular to a wet air pollution control device. Background Technology

[0002] Wet scrubbing, also known as wet scrubbing, is a technology that uses water (or other liquids) to contact dust-laden gas, involving heat and mass transfer, to separate dust particles from the gas through washing. Air pollution control is a very comprehensive and systematic process, involving many aspects such as environmental planning and management, energy utilization, and pollution prevention. Because the characteristics, conditions, and directions and priorities of comprehensive air pollution control vary from region to region (or city), it is difficult to find a comprehensive control measure suitable for all situations. Therefore, it is necessary to propose corresponding countermeasures tailored to local conditions.

[0003] In air pollution control, it is necessary to neutralize harmful substances in the atmosphere through chemical reactions. In practice, the treatment liquid is atomized and mixed with the gas. However, the gas becomes humid when passing through the treatment liquid, which affects its normal use in the next process. Even if a drying mechanism is set up to dry the gas, the equipment needs to be shut down when the materials in the drying mechanism are replaced. Otherwise, humid gas will still enter the next process during the replacement process. Moreover, the treatment liquid is inconvenient to process after use, and if it is only used once, a lot of treatment liquid will be wasted. Utility Model Content

[0026] Reference Figure 1-5A wet air treatment device includes a purification cylinder 1. The side wall of the purification cylinder 1 is equipped with an inlet pipe 4 with a flange, an outlet pipe 7 with a valve, and an inlet pipe 6 with a sealing cap. A conical mesh 16 and a water distribution plate 13 are fixedly installed inside the purification cylinder 1. Spray nozzles are evenly distributed at the bottom of the water distribution plate 13. A pressure pump 3 and a transmission pipe 2 are installed on the side wall of the purification cylinder 1. A three-way pipe 8 is connected to the side wall of the purification cylinder 1, and both ends of the three-way pipe 8 are equipped with valves. Both ends of the three-way pipe 8 are connected to connecting pipes 9, and the connecting pipes 9 are internally equipped with… The purification cylinder 1 is equipped with a drying plate 11 and an electric heating grid 12. Inside, there is an auxiliary mechanism for cleaning the conical mesh 16 and mixing the treatment liquid. During operation, the treatment liquid is first poured into the purification cylinder 1 through the feed pipe 6. Polluted gas is then introduced into the purification cylinder 1 through the air inlet pipe 4. The pressure pump 3 is then activated, transporting the treatment liquid to the water distribution plate 13 via the transmission pipe 2. The liquid is then sprayed out through nozzles at the bottom of the water distribution plate 13, thus spraying the polluted gas entering the purification cylinder 1 and dispersing harmful substances from the gas. The gas can be neutralized through a chemical reaction. The treated gas enters the three-way pipe 8 and then the connecting pipe 9. The gas is dried using the washing cotton in the connecting pipe 9, and then further dried using a heating grid. This facilitates further treatment of the atmosphere and avoids the atmospheric humidity affecting subsequent processes. After reacting with the exhaust gas, the treated liquid falls into the conical mesh 16, which filters out particulate matter and other impurities from the exhaust gas. The treated liquid then falls back to the bottom of the purification cylinder 1 for easy recycling. To ensure the concentration of the treated liquid, high-concentration treated liquid can be intermittently added through the feed pipe 6, allowing for continuous use. The three-way pipe 8 connects to two connecting pipes 9, both of which are connected to the next process. In practice, the valve on the three-way pipe 8 allows gas transmission using only one connecting pipe 9, facilitating the replacement of the drying plate 11 on the other connecting pipe 9 without shutting down the entire equipment.

[0027] Furthermore, the surface of the connecting pipe 9 is provided with a receiving groove for placing the drying plate 11, and a sealing plate 10 is provided at the open end of the receiving groove. The sealing plate 10 and the connecting pipe 9 are fixedly connected by bolts. The drying plate 11 is directly inserted into the receiving groove. The sealing plate 10 is used to seal the receiving groove. When replacing the drying plate 11, it is only necessary to remove the bolts on the sealing plate 10 to take out or install the drying plate 11.

[0028] Furthermore, the pressure pump 3 is fixedly installed on the side wall of the purification cylinder 1. The inlet end of the pressure pump 3 is inserted into the inside of the purification cylinder 1, and the outlet end of the pressure pump 3 is connected to the transmission pipe 2. The top end of the transmission pipe 2 passes through the purification cylinder 1 and is connected to the water distribution plate 13. The pressure pump 3 draws the treatment liquid at the bottom of the purification cylinder 1 into the transmission pipe 2, and then uses the transmission pipe 2 to transfer it to the water distribution plate 13.

[0029] Furthermore, the auxiliary mechanism includes a motor 5, which is fixedly installed on the top of the purification cylinder 1. The output shaft of the motor 5 rotates through the top of the purification cylinder 1. A connecting shaft 14 is fixedly installed at the port of the output shaft of the motor 5. A cleaning rod 17 is fixedly installed on the surface of the connecting shaft 14. The surface of the cleaning rod 17 is provided with bristles that act on the surface of the conical mesh 16. A vertical pipe 19 with a valve rotates through the bottom of the purification cylinder 1. The bottom of the conical mesh 16 is provided with an opening. The top and bottom openings of the vertical pipe 19 and the conical mesh 16 are connected. A sealing sleeve is provided at the position where the vertical pipe 19 rotates and connects with the purification cylinder 1. An extension rod 20 is fixedly installed at the bottom of the connecting shaft 14. The extension rod 20 is inserted into the interior of the vertical pipe 19. A bracket 21 is fixedly installed at the bottom end of the extension rod 20. The extension rod 20 and the vertical tube 19 are fixedly connected by the bracket 21. The stirring rods 18 are evenly fixedly installed on the surface of the vertical tube 19. When the auxiliary mechanism is in use, the motor 5 is started, the motor 5 drives the connecting shaft 14 to rotate, and the connecting shaft 14 drives the cleaning rod 17 to rotate. The brush bristles on the surface of the cleaning rod 17 are used to clean the conical mesh 16. The dirt on the conical mesh 16 can fall into the vertical tube 19 through the bottom opening and be discharged from the purification cylinder 1 through the vertical tube 19. When the connecting shaft 14 rotates, the extension rod 20 and the bracket 21 can also drive the vertical tube 19 to rotate, and the vertical tube 19 drives the stirring rod 18 to rotate. Thus, when adding high-concentration treatment liquid, all the liquids in the purification cylinder 1 can be quickly mixed, which facilitates continuous chemical neutralization reaction.

[0030] Furthermore, a baffle plate 15 is fixedly installed on the surface of the connecting shaft 14. By setting the baffle plate 15, the gas can be turbulent, so that the gas can be evenly mixed with the sprayed treatment liquid.

[0031] Furthermore, a vertical hole is provided at the center of the surface of the water distribution plate 13, the connecting shaft 14 passes through the vertical hole, the three-way pipe 8 is provided on the side wall of the purification cylinder 1 near the top, the air inlet pipe 4 is provided on the surface of the purification cylinder 1 near the middle, the discharge pipe 7 is provided on the side wall of the purification cylinder 1 near the bottom, and the feed pipe 6 is provided between the conical mesh 16 and the discharge pipe 7.

[0032] In summary, during operation, the treatment liquid is first poured into the purification cylinder 1 through the feed pipe 6, and the polluted gas is introduced into the purification cylinder 1 through the air inlet pipe 4. Then, the pressure pump 3 is started, and the treatment liquid is transported to the water distribution plate 13 through the transmission pipe 2. The spray nozzle at the bottom of the water distribution plate 13 sprays the polluted gas entering the purification cylinder 1, allowing the harmful substances in the gas to be neutralized through a chemical reaction. The treated gas then enters the three-way pipe 8, which in turn leads to the connecting pipe 9. The washing cotton in the connecting pipe 9 dries the gas, and then the heating grid further dries it, thus facilitating the next step of atmospheric treatment and avoiding atmospheric humidity. In cases where the process is affected by the next step, the treatment liquid, after reacting with the exhaust gas, falls into the conical mesh 16. The conical mesh 16 filters out particulate matter and other impurities from the exhaust gas, and then the treatment liquid falls back to the bottom of the purification cylinder 1, facilitating recycling. To maintain the concentration of the treatment liquid, high-concentration treatment liquid can be intermittently added through the feed pipe 6, allowing for continuous use. A three-way pipe 8 connects to two connecting pipes 9, both of which are connected to the next process step. In practice, a valve on the three-way pipe 8 allows gas transmission using only one connecting pipe 9, facilitating the operation of the other connecting pipe. 9. Replace the drying plate 11 without shutting down the entire equipment. The composition of the treatment liquid can be rationally proportioned according to the substances contained in the atmosphere. The drying plate 11 is directly inserted into the receiving tank, and the receiving tank is sealed by the sealing plate 10. When replacing the drying plate 11, simply remove the bolts on the sealing plate 10 to remove or install the drying plate 11. The pressure pump 3 draws the treatment liquid from the bottom of the purification cylinder 1 into the transmission pipe 2, and then transmits it to the water distribution plate 13. During use, the auxiliary mechanism starts the motor 5, which drives the connecting shaft 14 to rotate. The connecting shaft 14 drives the cleaning rod 17 to rotate, utilizing the surface of the cleaning rod 17. The brush bristles clean the conical mesh 16. The dirt on the conical mesh 16 can fall into the vertical pipe 19 through the bottom opening and be discharged from the purification cylinder 1 through the vertical pipe 19. When the connecting shaft 14 rotates, the extension rod 20 and the bracket 21 can also drive the vertical pipe 19 to rotate. The vertical pipe 19 drives the stirring rod 18 to rotate, so that when adding high-concentration treatment liquid, all the liquid in the purification cylinder 1 can be quickly mixed, which facilitates continuous chemical neutralization reaction. The sealing sleeve set on the surface of the vertical pipe 19 can play a sealing function without affecting the rotation of the vertical pipe 19. By setting the baffle 15, the gas can be turbulent, so that the gas can be evenly mixed with the sprayed treatment liquid.
