Problems solved by technology

[0003] In the current production of carbon disulfide, before the liquid sulfur is added to the reaction furnace, sulfur is first added through the sulfurizer, which is an open type sulfur addition. In the sulfur tank and reaction furnace, a large amount of gaseous sulfur will be produced in the high-temperature sulfurizing tank. Due to the open operation, a large amount of gaseous sulfur will be discharged indiscriminately. The impact of smoothness will also often cause disordered overflow of liquid sulfur, resulting in a large amount of sulfur that cannot be recycled, seriously polluting the environment

Abstract

The invention relates to an anti-leakage environment-friendly sulfur-adding device in the carbon disulfide production. The anti-leakage environment-friendly sulfur-adding device comprises a sulfur-adding tank (11) and a liquid sulfur conveying pipe (21); an enclosed outer cover (14) is arranged above the sulfur-adding tank (11); a gaseous sulfur recovery tube (15), a liquid sulfur inlet (23) and a liquid sulfur overflow opening (32) are formed in the outer cover (14); the liquid sulfur inlet (23) is connected with the liquid sulfur conveying pipe (21) and is provided with a control valve (22); a sulfur return pipe (31) is arranged behind the liquid sulfur overflow opening (32). Compared with the prior art, the anti-leakage environment-friendly sulfur-adding device provided by the invention has the benefits that the leakage of liquid sulfur and gaseous sulfur during sulfur adding in the carbon disulfide production can be prevented, and the liquid sulfur and the gaseous sulfur are effectively recovered.

Description

technical field [0001] The invention belongs to the technical field of carbon disulfide production, in particular to an anti-leakage and environment-friendly sulfuration device for carbon disulfide production. Background technique [0002] The semi-coke carbon disulfide production method is a very mature production process with simple process, rich resources, wide source of raw materials, low cost, but serious pollution. Sulfurizer is one of the important sources of pollution. [0003] In the current production of carbon disulfide, before the liquid sulfur is added to the reaction furnace, the sulfur is firstly added through the sulfurizer, which is an open type sulfuration, and the liquid sulfur is transported to the high-temperature sulfurizing tank through the liquid sulfur delivery pipe, and then further transported to the sulfurizing tank through the pipeline. In the sulfur tank and reaction furnace, a large amount of gaseous sulfur will be produced in the high-tempera...
