Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment equipment, in particular to epichlorohydrin waste gas purification treatment equipment. Background Art

[0002] Many industries such as petrochemicals, pharmaceuticals, and especially chemical industry sewage stations produce a large amount of VOCs and odorous gases, which affect the sustainable development of society and cause great harm to the physical and mental health of surrounding residents and corporate employees. At the same time, companies' environmental awareness continues to increase, and higher requirements are constantly being put forward for the factory environment. Develop and verify the combined technology of precious metal-loaded TiO2 nano-photocatalyst + biofilter + microbial spraying to decompose a variety of VOCs and odorous pollutants, providing valuable experience for companies to solve the current problems of waste gas treatment and further expand the construction of new projects. It provides a new successful treatment technology that can be used as a reference for the treatment of VOCs and odorous pollutants in similar sewage stations in the chemical industry, which has great market prospects.

[0003] The epichlorohydrin (recycling carbide slag and sodium sulfate) water treatment pool was originally open. As the environmental protection situation becomes increasingly severe, all pools are sealed and covered to recycle volatile gases. After unified recycling and treatment, there is still a faint odor. In order to solve this odor, a set of gas deodorization equipment is specially added. At the same time, an effective treatment method is found for the odorous waste gas of the epichlorohydrin wastewater treatment station, and valuable experience is provided for successful odor treatment. It can also demonstrate the effectiveness of the photocatalytic + biological filter + microbial spraying combined treatment technology for the treatment of halogenated odorous waste gas such as dichloropropene and chloropropylene.

[0004] At present, when the epichlorohydrin waste gas purification treatment equipment on the market is in use, a large amount of waste gas flows into the tank for photocatalysis. When the gas flow rate in the tank is too fast, part of the waste gas cannot be treated by light, which will reduce the treatment efficiency of the epichlorohydrin waste gas.
