Description

Technical Field

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

[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory premises. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead, mercury, beryllium compounds, soot, and industrial dust. When released into the atmosphere, they pollute the air. These substances enter the human body through the respiratory tract via various pathways; some cause direct harm, while others have a cumulative effect, further endangering human health. Different substances have different effects. Industrial waste gas treatment refers to the pretreatment of waste gases generated in industrial sites such as factories and workshops before their external discharge to meet national emission standards. Industrial waste gas contains a large number of substances harmful to human health; direct discharge exacerbates harm to human health and causes significant environmental pollution. However, existing waste gas treatment devices are not very effective. Utility Model Content

[0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides a waste gas degradation treatment device for industrial waste gas.

[0004] A waste gas degradation treatment device for industrial waste gas includes a waste gas treatment cylinder.

A filter hole is provided at the bottom of the partition. The spray chamber and the demisting chamber are connected through the filter hole. A filter screen is provided in the spray chamber, and a ball bearing is provided at the bottom of the filter screen. The spray chamber and the demisting chamber are filled with washing liquid. The waste gas enters the spray chamber, comes into contact with the washing liquid, and enters the demisting chamber through the filter hole. Then, it passes through an activated carbon adsorption box and an ultraviolet irradiation box in sequence.

[0005] Furthermore, the top of the spray chamber is provided with an air inlet pipe, and the top of the ultraviolet irradiation box is provided with an air outlet pipe.

[0006] Furthermore, a spray pipe is provided above the filter screen in the spray chamber, and the spray pipe is equipped with downward-facing nozzles. The end of the spray pipe extends out of the side wall of the exhaust gas treatment cylinder and is connected to a water pump.

[0018] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0019] according to Figure 1-5 As shown, a waste gas degradation treatment device for industrial waste gas includes a waste gas treatment cylinder 1. A partition 2 is provided in the middle of the waste gas treatment cylinder 1, which divides the waste gas treatment cylinder 1 into two relatively independent left and right parts: a spray chamber 3 and a demisting chamber 4. A filter hole 5 is provided at the bottom of the partition 2. The spray chamber 3 and the demisting chamber 4 are connected through the filter hole 5. A filter screen 6 is provided in the spray chamber 3, and a ball bearing 7 is provided at the bottom of the filter screen 6. The spray chamber 3 and the demisting chamber 4 are filled with washing liquid. The waste gas enters the spray chamber 3, comes into contact with the washing liquid, and enters the demisting chamber 4 through the filter hole 5. Then, it passes through an activated carbon adsorption box 8 and an ultraviolet irradiation box 9 in sequence.

[0020] In the above-mentioned specific technical solution, the staff can add different washing liquids to the gas treatment cylinder according to the different exhaust gases. After the exhaust gas is washed by the washing liquid, it is conditioned by the demister, so that the gas meets the emission standards. The activated carbon adsorption box 8 can clean the toxic substances in the exhaust gas. In addition, the ultraviolet light emitted by the ultraviolet lamp 19 can break down pollutants in the odorous gas. At the same time, after being irradiated by ultraviolet light, it will form an oxidant with strong oxidizing properties, which can oxidize the pollutants in the exhaust gas and further improve the treatment effect of the exhaust gas.

[0021] The exhaust gas enters the spray chamber 3, comes into contact with the washing liquid, and enters the demisting chamber 4 through the filter hole 5. The ball bearing 7 can disperse the exhaust gas, so that it can fully contact the washing liquid and increase the washing effect of the exhaust gas.

[0022] The top of the spray chamber 3 is provided with an air inlet pipe 10, and the top of the ultraviolet irradiation box 9 is provided with an air outlet pipe 11.

[0023] The spray chamber 3 is provided with a spray pipe 12 above the filter screen 6. The spray pipe 12 is provided with downward nozzles. The end of the spray pipe 12 extends out of the side wall of the exhaust gas treatment cylinder 1 and is connected to the water pump. The washing liquid is added into the exhaust gas treatment cylinder 1 through the spray pipe 12. When the washing liquid needs to be replaced after long-term use, the washing liquid is discharged and then new washing liquid is added through the spray pipe 12.

[0024] The demister chamber 4 is equipped with a demister, which includes several folded demister plates 13 connected by connecting rods 14. The top of each demister plate 13 is connected to a fixing ring 15, which is connected to the inner wall of the demister chamber 4. The bottom of the demister is higher than the washing liquid level. The top of the demister chamber 4 is equipped with a connecting pipe 16, which connects the demister chamber 4 to the activated carbon adsorption box 8. When the exhaust gas containing water vapor rises, it comes into contact with the demister plates 13. As the exhaust gas continues to rise, most of the liquid droplets adhere to the demister plates 13, resulting in water vapor separation.

[0025] The activated carbon adsorption box 8 is provided with several activated carbon plates 17. The activated carbon plates 17 are inserted from the top of the activated carbon adsorption box 8, and a sealing gasket 18 is provided at the top insertion port, which helps to increase the sealing performance of the activated carbon adsorption box 8. The activated carbon plates 17 are inserted from the top of the activated carbon adsorption box 8, and the top of the activated carbon plates 17 protrudes from the activated carbon adsorption box 8, making it convenient to replace the activated carbon plates 17.

[0026] The exhaust gas enters the bottom of the ultraviolet irradiation box 9 from the activated carbon adsorption box 8. The ultraviolet irradiation box 9 is equipped with several ultraviolet lamps 19. The exhaust gas is discharged after being irradiated by the ultraviolet lamps 19.

[0027] Mounting plates 20 are provided on both sides of the ultraviolet irradiation box 9. One mounting plate 20 is provided with a fixing frame 21, and the other mounting plate 20 is provided with a slide rail 22. The slide rail 22 is slidably connected to the slide plate 23. The two ends of the ultraviolet lamp 19 are respectively mounted on the fixing frame 21 and the slide plate 23. When the ultraviolet lamp 19 needs to be replaced, the slide plate 23 can be moved to remove the ultraviolet lamp 19.
