Description

Technical Field

[0001] This utility model relates to the field of spray tower technology, specifically to a spray tower for waste gas treatment. Background Technology

[0002] Waste gas treatment, also known as waste gas purification, mainly involves spray towers. The main functions of spray towers in waste gas treatment include purifying waste gas, removing harmful substances, and regulating waste gas parameters. Spray towers achieve the purpose of purifying waste gas by fully contacting the waste gas with the circulating spray liquid, absorbing and neutralizing the harmful components in the waste gas.

[0003] Chinese patent CN216171361U discloses an air spray tower, which includes a spray tower, an exhaust pipe connected to the top of the spray tower, an air pressure valve installed on the exhaust pipe, and an air supply component connected to one side of the spray tower.

[0004] Although the aforementioned patent uses a first water pump to pump the alkali solution from the alkali tank into the outlet pipe, and then the outlet pipe transports the alkali solution to the top of the spray tower and sprays it out by the first spray plate, thereby making the circulating alkali solution spray more evenly and improving the absorption rate of the waste gas, the liquid falling to the bottom of the spray tower adsorbs impurities. If the liquid at the bottom of the spray tower is not filtered and is re-pumped out by the second water pump to spray the waste gas, it will cause damage to the second water pump and affect its service life. While extending the contact time between the waste gas and the liquid can improve the absorption rate of the waste gas, the slow rise of the waste gas will reduce the treatment efficiency of the spray tower. Therefore, there is an urgent need for a new type of spray tower for waste gas treatment to solve these problems. Utility Model Content

[0013] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: This invention features symmetrically arranged cleaning boxes on both sides of the storage tank. A drive motor rotates a screw, positioning the filter frame below the drain pipe for easy filtration of the liquid sprayed with waste gas. When the filter frame needs cleaning due to filtration of a large amount of impurities, the motor rotates the screw to move the filter frame containing the impurities into one of the cleaning boxes. Moving the U-shaped filter plate in the filter further filters the liquid discharged from the drain pipe, preventing impurities from flowing into the storage tank when replacing the filter frame. Once the filter frame is in the cleaning box, the other filter frame moves below the drain pipe. Opening the cleaning box and using a pull rod allows the filter frame to be removed from the support cylinder, making cleaning easier without interrupting the waste gas treatment process of the spray tower. The perforated plate allows the waste gas to float upwards more effectively, while the liquid sprayed from the spray plate penetrates downwards, contacting the waste gas box rising from the perforated plate. This increases the contact time between the liquid and the gas without affecting the upward speed of the waste gas, thus preventing any impact on the spray tower's waste gas treatment speed.

The pull rod 12 can easily remove the filter frame 11 from the support cylinder 10. A perforated plate 13 is installed inside the spray tower body 2. The spray tower body 2 can firmly fix the perforated plate 13. The perforated plate 13 can facilitate better floating of the waste gas.

[0018] like Figures 1-3As shown, in this embodiment, an air inlet pipe 14 is provided on one side wall of the spray tower body 2 below the perforated plate 13. A spray plate 15 is installed at the top inside the spray tower body 2. A water pump 16 is provided on one side wall of the liquid storage tank 3. A water supply pipe 17 connecting the liquid storage tank 3 and the spray plate 15 is installed on the water pump 16. A drain pipe 18 is centrally connected to the bottom of the spray tower body 2. The air inlet pipe 14 facilitates the delivery of waste gas into the spray tower body 2. The water pump 16 facilitates the extraction of liquid from the liquid storage tank 3. The water supply pipe 17 facilitates the delivery of liquid to the spray plate 15. The spray tower body 2 and the liquid storage tank 3 are bolted to the base 1. The cleaning box 4 is bolted to the liquid storage tank 3. A cleaning door is provided at the top of the cleaning box 4. The air inlet pipe 14 is connected to the flange of the spray tower body 2. A blower is provided on the air inlet pipe 14. The spray tower body 2 is bolted to the spray plate 15. The liquid storage tank 3 is bolted to the water pump 16. The liquid storage tank 3, water pump 16, and spray plate 15 are all threadedly connected to the water supply pipe 17. An exhaust pipe is provided on one side of the top of the spray tower body 2. The spray plate 15 can better spray the liquid evenly. The drain pipe 18 facilitates the discharge of the liquid that has adsorbed waste gas impurities from the spray tower body 2.

The spray tower body 2 is bolted to the hollow plate 13.

[0019] The specific implementation process of this embodiment is as follows: In use, firstly, exhaust gas is introduced into the spray tower body 2 through the air inlet pipe 14. At this time, the water pump 16 is started to transport the liquid in the storage tank 3 to the spray plate 15 through the water delivery pipe 17. The spray plate 15 sprays the liquid evenly. By symmetrically setting cleaning boxes 4 on both sides of the storage tank 3, the drive motor 5 drives the screw 6 to rotate, so that the filter frame 11 is located below the drain pipe 18, which facilitates the filtration of the liquid sprayed from the exhaust gas. When the filter frame 11 filters a large amount of impurities and needs to be cleaned, the motor 5 drives the screw 6 to rotate, so that the filter frame 11 that filters the impurities moves to one of the cleaning boxes 4. Then, the U-shaped filter plate 9 in the filter can be moved to clean the liquid discharged from the drain pipe 18. The liquid is filtered to prevent impurities from flowing into the storage tank 3 when the filter frame 11 is replaced. When the filter frame 11 is moved into the cleaning tank 4, and the other end of the filter frame 11 is moved below the drain pipe 18, the cleaning can be opened and the filter frame 11 can be removed from the support cylinder 10 by pulling the lever 12. This makes it easier to clean the impurities in the filter frame 11, and at the same time, it is not necessary to stop the treatment of exhaust gas by the spray tower body 2. The perforated plate 13 allows the exhaust gas to float upward better, and the liquid sprayed from the spray plate 15 penetrates downward and can contact the exhaust gas box that rises from the perforated plate 13. This increases the contact time between the liquid and the exhaust gas without affecting the upward floating speed of the exhaust gas, thereby avoiding affecting the treatment speed of the exhaust gas by the spray tower.
