Description

Technical Field

[0001] This utility model relates to the field of washing and deodorization technology, and in particular to a chemical washing tower deodorization device for multi-stage filtration circulating water. Background Technology

[0002] Chemical scrubbing towers are widely used for industrial waste gas treatment and odor control. Their core principle is the reaction of chemical agents with odorous substances in the waste gas, producing odorless or low-odor substances, thereby purifying the air. During operation, waste gas enters the scrubbing tower, and a solution from the circulating water tank is sent to the tower for spray deodorization. The sprayed solution is then returned to the circulating water tank for reuse, and the deodorized gas is discharged from the outlet.

[0003] In existing chemical scrubbing and deodorizing devices, the circulating water is not filtered during conventional design and operation. Impurities in the gas treated by spraying enter the circulating water along with the spray liquid. As these impurities settle and accumulate, they can clog water pumps or nozzles, increasing equipment failure rates, affecting equipment operation, and increasing operating and maintenance costs. Furthermore, unfiltered circulating water can affect the deodorization effect and shorten the service life. Utility Model Content

[0004] The main objective of this invention is to provide a chemical scrubbing tower deodorization device for multi-stage filtration and circulating water, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The scrubbing tower body is provided with an air inlet and a packing layer inside. A spray pipe with nozzles is installed inside the scrubbing tower body. An observation window is provided on the scrubbing tower body. A third drain outlet is provided at the bottom of the scrubbing tower body. A connecting pipe connects the water tank and the scrubbing tower body. A fixing plate is provided inside the water tank. A filter assembly is provided on the fixing plate. A slope is provided at the bottom of the water tank. A first drain outlet and a second drain outlet are provided on the water tank.

[0007] Preferably, the washing tower body has an internal demister layer located above the spray nozzle, and the washing tower body has an air outlet located directly above the demister layer.

[0008] Preferably, the water tank is equipped with a circulating water pump at one end, and a delivery pipe is connected to the circulating water pump, with the end of the delivery pipe connected to the spray pipe.

[0009] Preferably, the water tank is provided with a cover on the top, and the cover is provided with an inspection plate, and the water tank is provided with a water inlet.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-4 As shown, a multi-stage filtration circulating water chemical scrubbing tower deodorization device includes a scrubbing tower body 1 and a water tank 8. The scrubbing tower body 1 is provided with an air inlet 2, and the interior of the scrubbing tower body 1 is provided with a packing layer 3. The interior of the scrubbing tower body 1 is equipped with a spray pipe 4, and the spray pipe 4 is provided with a nozzle 5. The scrubbing tower body 1 is provided with an observation window 20. The bottom of the scrubbing tower body 1 is provided with a third drain outlet 21. The water tank 8 is connected to the scrubbing tower body 1 by a connecting pipe 9. The interior of the water tank 8 is provided with a fixing plate 13, and the fixing plate 13 is provided with a filter assembly 16. The bottom of the interior of the water tank 8 is provided with a slope 12, and the water tank 8 is provided with a first drain outlet 14 and a second drain outlet 15.

[0020] The main body 1 of the scrubbing tower has a demisting layer 6 inside, which is located above the spray pipe 4. An air outlet 7 is located directly above the demisting layer 6 on the main body 1 of the scrubbing tower. A circulating water pump 10 is located at the end of the water tank 8, and a delivery pipe 11 is connected to the circulating water pump 10. The end of the delivery pipe 11 is connected to the spray pipe 4. A tank cover 17 is located on the top of the water tank 8, and an inspection plate 18 is installed on the tank cover 17. A water inlet 19 is also provided on the water tank 8.

[0021] When using the device to deodorize exhaust gas, the water tank 8 stores a solution containing chemical agents. Exhaust gas is introduced into the body of the scrubbing tower 1 through the air inlet 2. Then, the exhaust gas moves upward, passes through the packing layer 3, and enters the spray layer. When the exhaust gas enters the device, the circulating water pump 10 runs to draw the solution in the water tank 8 into the delivery pipe 11, and finally sprays it out from the nozzle 5 on the spray pipe 4. This allows the exhaust gas flowing upward from the bottom of the packing layer 3 to fully contact and react with the downward sprayed solution through the packing gaps to achieve the purpose of deodorization. The solution containing impurities falls into the bottom of the scrubbing tower body 1 for the first settling. The gas that has been sprayed passes through the demisting layer 6 for dehumidification and is then discharged from the air outlet 7. After the first settling, the supernatant enters the water tank 8 through the connecting pipe 9. Under the action of the fixing plate 13 and the filter assembly 16, the solution in the water tank 8 undergoes a second settling and filtration. The supernatant from the second settling and filtration passes through the filter assembly 16 and enters the other end of the water tank 8 for a third settling. The supernatant after the third settling can continue to be used as a spraying liquid, thus achieving the purpose of recycling.

[0022] When the circulating liquid no longer has a deodorizing effect, the drain outlet can be opened. Impurities and solution at the bottom of the main body 1 of the scrubbing tower are discharged from the third drain outlet 21, while impurities and solution on the ramp 12 of the water tank 8 are discharged from the first drain outlet 14 and the second drain outlet 15, respectively. After discharge, liquid can be replenished through the water inlet 19. If it is necessary to clean the filter assembly 16, the inspection plate 18 on the cover 17 can be opened, and one set of filter assemblies 16 can be disassembled for cleaning. After cleaning, they can be reinstalled. During the cleaning process, the other set of filter assemblies 16 continues to perform its filtering function normally, ensuring the normal operation of the device.

[0023] According to the above implementation scheme, the filter assembly 16 includes a perforated plate 1601, an insert rod 1602, a side rod 1603, an assembly groove 1604, a connecting block 1605, and an elastic sheet 1606. The perforated plate 1601 is fixedly connected to the insert rod 1602, and the insert rod 1602 is inserted into the fixed plate 13. The perforated plate 1601 has through holes evenly distributed. The side rod 1603 is fixed at both ends of the perforated plate 1601. The assembly groove 1604 is opened on the side rod 1603. The connecting block 1605 and the elastic sheet 1606 are fixedly connected, and the connecting block 1605 is embedded in the assembly groove 1604 on the side rod 1603.

[0024] When using filter assembly 16, the supernatant from the second sedimentation filtration passes through the through holes in the porous plate 1601 for filtration. Due to the action of the insert rod 1602 and the elastic plate 1606 on the side rod 1603, the porous plate 1601 has good stability. When it is necessary to disassemble the porous plate 1601, simply lift it up for removal, and then clean it. After cleaning, the porous plate 1601 is installed onto the fixing plate 13 via the insert rod 1602. The elastic plate 1606 on the side rod 1603 abuts against the inner wall of the water tank 8, providing stable support. When needed, the connecting block 1605, which mounts the elastic plate 1606, can be removed from the assembly slot 1604 for replacement, offering high flexibility in use.

[0025] It should be noted that by setting a third drain outlet 21 at the bottom of the washing tower, setting a ramp 12 inside the water tank 8, and setting a first drain outlet 14 and a second drain outlet 15 at the lowest part of the ramp 12 on both sides of the fixed plate 13 inside the water tank 8, and setting a filter assembly 16 on the fixed plate 13, the entire device forms a multi-stage filtration and sedimentation effect, which can effectively remove impurities in the circulating water, prevent the water pump or nozzle 5 from clogging, reduce the failure rate, and reduce operation and maintenance costs. Setting two sets of completely overlapping filter assemblies 16 provides a backup effect. When one set is pulled out for cleaning, it does not affect the normal operation of filtration. A rod 1602 is set at the lower end of the perforated plate 1601, and elastic plates 1606 are set on the side rods 1603 at both ends. This ensures the stability of the perforated plate 1601 after installation while ensuring quick disassembly and assembly. The elastic plates 1606 are installed in the assembly groove 1604 through the connecting block 1605 and can be replaced.

[0026] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
