Waste gas purification device for sewage treatment station of sterile bulk drug production line

Abstract

The invention discloses a waste gas purification device for a sewage treatment station of a sterile bulk drug production line. The waste gas purification device comprises an alkali liquor spraying andleaching device, a dewatering and demisting device, a composite photocatalysis device, a microbial degradation device, a peculiar smell controller and a chimney, which are sequentially communicated according to the flowing direction of waste gas, the alkali liquor spraying and leaching device is used for spraying alkaline liquid; the dehydration and demisting device is used for drying waste gas;the composite photocatalysis device is used for removing volatile organic compounds in the waste gas; the microbial degradation device is used for degrading the waste gas; the peculiar smell controller is used for removing volatile molecules with small molecular weight; and the chimney is used for discharing the purified gas; the device also includes a centrifugal fan. The waste gas purification device can effectively remove pollutants such as H2S, NH3, methyl mercaptan, dimethyl sulfide, methyl sulfide, methyl disulfide and malodorous gas in waste gas, and the waste gas treatment effect is good.

Description

technical field [0001] The invention relates to the technical field of exhaust gas purification, in particular to an exhaust gas purification device for a sewage treatment station of a sterile bulk medicine production line. Background technique [0002] During the production of sterile raw materials, a large amount of waste gas will be generated, and the waste gas contains a large amount of pollutants such as H2S, NH3, methyl mercaptan, methyl sulfide, methyl sulfide, methyl disulfide and malodorous gas. The exhaust gas produced is highly polluting, the discharge volume is large, and the pollution components are complex and changeable. In particular, the malodorous components in the exhaust gas are likely to cause relatively large pollution to the surrounding environment and the factory environment, and it is inevitable to disturb the residents. For the production of sterile raw materials, a large amount of waste gas will be generated. At present, dry neutralization method, ...

Problems solved by technology

The exhaust gas produced is highly polluted, the discharge volume is large, and the pollution components are complex and changeable. In particular, the malodorous components in the exhaust gas are likely to cause relatively large pollution to the surrounding environment and the factory environment, and it is difficult to avoid the phenomenon of disturbing the people.

For the production of sterile raw materials, a large amount of waste gas will be generated. At present, dry neutralization method, composite photocatalysis, ion deodorization method, absorption method, adsorption method, microbial degradation method, composite active oxygen method, trace Nutrient element decomposition method, combustion method and condensation method are used for treatment, but the above-mentioned methods cannot remove xylene, non-methane and malodorous pollutants in the exhaust gas, and the exhaust gas treatment effect is poor.
