Abstract

The invention relates to a process of comprehensively treating waste slag produced from organic silicon, aiming at continuously treating organic silicon slurry slag. In the process, whitewash and the organic silicon slurry slag are utilized for polymerization reaction, various generated pollutants are respectively treated, thus zero emission of gas is achieved, and air pollution is basically free. The process comprises the following specific steps: pumping exterior drainage from a sewage station 1 into a lime pool through a pump so as to dissolve the externally added lime into the whitewash, wherein the pH of the whitewash is more than or equal to 11; pumping the whitewash into a slurry slag treatment reactor through a mortar pump; and then adding nitrogen in a slurry slag tank so as to punch to 0.03MP, thus pressing the slurry slag into the slurry slag treatment reactor for reaction, wherein hydrolyzates can be externally sold, and monomers such as gas and the like can be absorbed though an absorption tower. Compared with the traditional organic silicon slurry slag treatment process, the process in the invention has the advantages that the organic silicon slurry slag is fully utilized, pollution is reduced to the minimum, and the organic silicon slurry slag is continuously treated, thereby achieving zero emission and basically having no air pollution.

Description

technical field [0001] The invention provides a process for treating pulp and slag, in particular to a process for comprehensively treating pulp and slag of organic silicon production waste. Background technique [0002] With the improvement of people's living standards and comprehensive national strength in our country, the demand for organic silicon monomers and organic silicon materials has increased rapidly. In the past 10 years, the annual demand growth of organic silicon monomers in my country has been above 20%. As the domestic production of organic silicon monomers lags behind the growth of demand, a large number of organic silicon monomers and products are imported every year, and the import volume accounts for more than 70% of the domestic consumption. At the same time, the processing of organosilicon products in my country is also growing rapidly. The production capacity of existing organosilicon devices in China is far from meeting the market demand. In the past...
