Embodiment Construction

[0027] After the exhaust gas from a rubber factory is introduced into the 3-stage serial spray tower (7.9% NaOH solution), the effluent is added to the heating reaction kettle with a heating temperature of 107 degrees Celsius and a pressure of 0.185 MPa, heated until the precipitate is dissolved, and then introduced into the plate tower containing mercury In the middle, after flowing out, it is heated to 52 degrees Celsius to produce red cinnabar, and the carbon disulfide is evaporated, condensed, recycled and reused. After the cinnabar is filtered and cleaned, it fully meets the requirements as a pigment. There is no waste gas emission and waste liquid flow out during the whole process, which can Compared with the Claus method, the consumption is reduced by about 37%, and cinnabar can be sold as pigment and Chinese medicinal material.

Abstract

The invention relates to a method for treating a waste gas containing hydrogen sulfide and carbon disulfide. According to the method disclosed by the invention, sulfur elements form precipitates by adopting a precipitation method, and lattice conversion is carried out on the precipitates in a liquid phase to enable the precipitates to be converted to cinnabars with a certain economical value, so that incineration of the traditional process and the extra treatment process are avoided.

Description

technical field [0001] The invention relates to a method for catalyzing waste of hydrogen sulfide, carbon disulfide and sulfur-containing organic matter. Background technique [0002] Rubber additives M, DM, CBS, NOBS, etc. are very important auxiliary additives in the rubber industry. With the huge demand of my country's automobile and other industries, the rapid development of these industries has been driven, resulting in a rapid increase in output. At present, the commonly used method in China is to synthesize the rubber accelerator M first, and use it as a raw material to synthesize other accelerators. Therefore, the rubber accelerator M has become an important chemical raw material and finished product. According to data, from 2002 to 2005, the output of accelerator M in my country increased from 17,800 tons to 44,000 tons (Rubber Auxiliary Production Status and Market Analysis, Liang Cheng, Chemical Industry, Volume 25, Issue 6, 2007). The method of using synthetic ...
