Problems solved by technology

However, since organic silicon waste liquid easily reacts with moisture in the air to generate hydrogen chloride gas, long-term storage will seriously corrode the storage tank, and the released hydrogen chloride gas will cause the tank body to expand and deform, and even cause leakage accidents

Description

technical field [0001] The invention relates to the technical field of organosilicon industry, and more specifically, relates to a treatment device and method for organosilicon waste liquid. Background technique [0002] Organosilicon material is a new type of synthetic chemical material based on organosilicon compounds. Due to its excellent performance, it is widely used in aerospace, electronics, automobiles, shipbuilding, light industry, machinery, agriculture, and daily chemicals. And medical and health industries, known as "industrial vitamins" or "industrial monosodium glutamate". In recent years, the organosilicon industry has developed rapidly in China, among which the development of organosilicon materials based on methylchlorosilane is particularly rapid. However, with the continuous expansion of the output of methylchlorosilane monomer, the by-product organosilicon waste liquid How to economically and effectively utilize organic silicon waste liquid has become an...
