Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an exhaust duct for organic waste gas treatment. Background Art

[0002] Organic waste gas treatment refers to the adsorption, filtration and purification of organic waste gas generated in the industrial production process. Usually, organic waste gas treatment includes formaldehyde organic waste gas treatment, benzene, toluene, xylene and other benzene-related organic waste gas treatment, acetone butanone organic waste gas treatment, and air purification treatment of organic matter such as carbon, hydrogen and oxygen. In the process of treating organic waste gas, an exhaust duct for organic waste gas treatment is needed.

[0003] An exhaust duct for treating organic waste gas disclosed in the Chinese utility model patent application disclosure CN213101484U includes a tube body, a filter mechanism No. 1 is provided at the air inlet inside the tube body, a fixing mechanism is provided on the outer surface of the tube body, the tube body is fixedly connected to the filter mechanism No. 1 through the fixing mechanism, and a filter mechanism No. 2 is fixedly installed inside the tube body. The exhaust duct for treating organic waste gas described in the utility model is used in conjunction with the filter mechanism No. 1 and the filter mechanism No. 2. The honeycomb holes on the surface of the activated carbon net can adsorb most of the organic waste gas, and a small part of the organic waste gas passes through the activated carbon net and enters the tube cavity between the filter mechanism No. 1 and the filter mechanism No. 2. Since the surface of this part of the tube cavity is provided with an oxidant coating, the organic waste gas can be catalytically oxidized under the action of ultraviolet light, and then the organic waste gas can be completely cleaned, which has a good environmental protection effect.

[0004] However, the device lacks the function of replacing the internal device. When in use, the internal device cannot be replaced for a long time, which causes a lot of troubles, resulting in aging of the internal device, poor treatment effect on organic waste gas, and slow working efficiency. In addition, the device also lacks the function of extending the pipeline. When in use, the length of the pipeline cannot be adjusted according to the actual situation, which causes a lot of troubles, resulting in greater limitations in the use of the pipeline, and inconvenience for the staff to use.
