Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a waste gas treatment device in the production of triphenylphosphine. Background Art

[0002] Triphenylphosphine is a white loose powder, which is easily soluble in alcohol, benzene and chloroform, slightly soluble in esters, and almost insoluble in water. It is a triphenyl substituted product of phosphine, which mainly exhibits reducing and nucleophilic properties. It is the basic raw material of rhodium phosphine complex catalyst and has a wide range of uses in domestic petrochemical industry. Triphenylphosphine is also used in the fields of pharmaceutical industry, organic synthesis, analysis, etc. Triphenylphosphine can also be used as a brightener in dyeing process, polymer polymerization, antioxidant for color film development, stabilizer for polyepoxidation, and analytical reagent. In the process of producing triphenylphosphine, raw materials and organic solvents such as methanol, tetrahydrofuran and benzene are required, so a large amount of volatile organic waste gas will be generated. The existing waste gas will be transported into a series of cleaning processes such as water washing tower and alkali washing tower. At present, waste gas pipelines are usually used to transport waste gas into water washing tower and alkali washing tower. The waste gas contains harmful gases and particulate matter. When the waste gas pipeline transmits waste gas for a long time, particulate matter in the waste gas will remain in the pipeline, so that the particulate matter will stick to the inner wall of the waste gas pipeline, thereby affecting the normal progress of the pipeline in transporting waste gas.
