Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to an acid and alkali waste gas treatment device. Background Technology

[0002] With the increasing severity of environmental problems, environmental protection and pollution control have received more and more attention. Among environmental pollution, air pollution is extremely serious, and its harm to human beings, animals and plants, and climate is also enormous. There are many factors that cause air pollution, such as industrial and domestic stoves and heating boilers, transportation, and smoke from forest fires. However, industrial pollution is a major source of air pollution. The main sources of acid and alkali mist exhaust gases are acidic and alkaline exhaust gases emitted during processes in industries such as chemical, electronics, metallurgy, electroplating, textile, food, and machinery manufacturing. For example, the air pollution caused by acid mist gases from seasoning food, acid production, pickling, electroplating, electrolysis, and storage batteries causes significant harm to human beings.

[0003] The applicant discovered through a search that a Chinese patent discloses a "waste gas treatment device" with publication (announcement) number "CN219539750U". This patent mainly uses a filter screen and a cover. A reset component provides force to the filter screen, with the force directed away from the airflow direction. The waste gas enters the cover along the airflow direction. Since the speed of the waste gas transmission is not constant, the thrust of the waste gas on the filter screen is also not constant. The direction of the thrust of the waste gas on the filter screen is parallel to the airflow direction, while the force of the reset component on the filter screen is directed away from the airflow direction. Under the combined action of the waste gas and the reset component, the filter screen reciprocates, which facilitates the shaking off of dust from the surface of the filter screen, reducing the accumulation of dust on the filter screen surface and helping to improve the overall filtration effect.

[0004] However, the following shortcomings still exist:

[0005] 1. When cleaning the dust shaken off the filter screen inside the exhaust gas treatment device and cleaning the filter screen, it is necessary to stop the exhaust gas treatment device and then disassemble the treatment device. The operation is complicated and affects the efficiency of exhaust gas treatment. In addition, disassembling and reassembling the exhaust gas treatment device will affect the sealing of the exhaust gas treatment device, thus affecting the treatment effect.

[0006] 2. The gas after passing through the waste gas treatment device is not fully recycled;

[0007] Therefore, an acid and alkali waste gas treatment device is proposed. Utility Model Content

[0008] The purpose of this invention is to provide an acid and alkali waste gas treatment device.

[0025] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Please see the appendix Figure 1 - Appendix Figure 5 A connecting pipe 20 is fixedly installed on the surface of the filter box 1. A spray box 15 is fixedly installed at one end of the connecting pipe 20. A first infusion pipe 21 is fixedly installed on the top of the spray box 15. An acidic neutralization liquid pool 18 is fixedly installed at one end of the first infusion pipe 21. A first nozzle 23 is fixedly installed at the other end of the first infusion pipe 21. A first valve 16 is fixedly installed in the middle of the first infusion pipe 21. A second infusion pipe 22 is fixedly installed on the top of the spray box 15. An alkaline neutralization liquid pool 19 is fixedly installed at one end of the second infusion pipe 22. A second nozzle 24 is fixedly installed at the other end of the second infusion pipe 22. A second valve 17 is fixedly installed in the middle of the second infusion pipe 22. A pipe support 11 is fixedly installed on the top of the filter box 1. A first exhaust pipe 9 is fixedly installed on the top of the pipe support 11. A box 29 is fixedly installed at the bottom of the filter box 1. A support plate 30 is fixedly installed at the bottom of the filter box 1. A fixing plate 34 is fixedly installed on the top of the purification box 31. A second motor 33 is fixedly installed in the middle of the fixing plate 34.

[0027] Example 1: This utility model discloses an acid and alkali waste gas treatment device, including a filter box 1. Movable holes 25 are provided on both sides of the outer wall of the filter box 1. Rubber sealing rings 2 are fixedly installed on the outer surface of the filter box 1 located outside the movable holes 25. A fixing frame 13 is also fixedly installed on the outer wall of the filter box 1. A first motor 14 is fixedly installed in the middle of the fixing frame 13. A second pulley 8 is fixedly installed at the output end of the first motor 14. A belt 7 is movably connected to the outside of the second pulley 8. A transmission belt 3 is movably connected to one end of the belt 7. A support wheel 26 is movably installed at the other end of the transmission belt 3, which passes through the movable holes 25 on the filter box 1. A filter frame 27 is fixedly installed on the top of the transmission belt 3. A filter layer 4 is filled inside the filter frame 27.

[0028] Specifically, after the filter layer 4 adsorbs harmful substances and solid particles in the exhaust gas, the first motor 14 drives the conveyor belt 3 to rotate in a circular motion, which can quickly and conveniently replace the filtered filter layer 4 without stopping the operation. The rubber sealing ring 2 between the filter box 1, the conveyor belt 3, and the filter layer 4 can maintain the airtightness of the filter box 1 when replacing the filter layer 4. The ring design of the conveyor belt 3 can filter the exhaust gas twice, resulting in better filtration effect.

[0029] In Example 2, a connecting hose 12 is fixedly installed on the surface of the spray box 15. A purification box 31 is fixedly installed at one end of the connecting hose 12. A second air outlet pipe 32 is fixedly installed on the top of the purification box 31. A fan 28 is fixedly installed in the middle of the second air outlet pipe 32. A first air outlet pipe 9 is fixedly installed at the air outlet end of the fan 28.

[0030] Specifically, the treated clean gas is discharged through the second outlet pipe 32, and part of the clean gas is blown out from the first outlet pipe 9 by the fan 28, which can wash the particulate matter on the surface of the filter layer 4. The blown-off particulate matter falls into the box 29 for centralized treatment.

[0031] Working principle:

[0032] First, the acidic and alkaline waste gas enters the filter box 1 through the inlet pipe 10. After filtration for a period of time, the filter layer 4 adsorbs the harmful substances and particulate matter in the acidic and alkaline waste gas. The first motor 14 is turned on, which drives the second pulley 8 to rotate. The second pulley 8 drives the first pulley 6 to rotate through the belt 7. The first pulley 6 drives the rotating wheel 5 to rotate. The conveyor belt 3 moves in a circular motion under the drive of the rotating wheel 5. The filter layer 4 can be made of activated carbon material, which can be quickly and conveniently replaced without stopping the machine and without affecting the normal operation of the filter box 1. Rubber sealing rings 2 are set between the filter box 1, the filter layer 4, and the conveyor belt 3 to ensure the sealing effect of the filter box 1 when replacing the filter layer 4. The waste gas treated by the filter box 1 enters the spray box through the connecting pipe 20. 15. When the exhaust gas is acidic, open the second valve 17 and spray an alkaline neutralizing solution to treat the exhaust gas. When the exhaust gas is alkaline, open the first valve 16 and spray an acidic neutralizing solution to treat the exhaust gas. The gas treated by the neutralizing solution is discharged from the first outlet pipe 9. The first outlet pipe 9 is set in an L-shape, and the outlet is set horizontally with the filter layer 4. After adsorbing the acidic and alkaline exhaust gas, the filter layer 4 will adsorb solid particulate matter. When it is replaced by the conveyor belt 3, the clean gas after treatment and purification can be blown and washed by the fan 28 to blow out the solid particulate matter on the filter layer 4. The blown particulate matter falls into the box 29. While blowing and washing the filter layer 4, the treated gas can be recycled, which is environmentally friendly. At this point, the entire process is completed.
