Continuous carbon disulfide production process and device adopting coke method

Abstract

The invention belongs to the technical field of carbon disulfide production by coke methods and aims to solve the problems that in an intermittent carbon disulfide production process adopting a traditional coke method, when coke raw materials are added, sulfur needs to stop adding, and environmental safety is caused during material adding and slag discharging. The invention provides a continuous carbon disulfide production process adopting the coke method. The process flow comprises the steps of pretreatment of raw materials, synthetic reaction, desulfuration, condensation, purification by rectification and tail gas treatment. According to the continuous production process disclosed by the invention, when the coke raw materials are added in a reaction furnace in working procedures of the synthetic reaction or slag is discharged from the reaction furnace, gases such as CS2 in the reaction furnace are displaced by inert gases and cannot leak out of the furnace. According to the continuous production process, when the coke raw materials are added into the gasification reacting furnace in working procedures of the synthetic reaction after a cover of the gasification reacting furnace is opened, intermittent production subjected to sulfur addition stopping is eliminated, so that the problem that environmental safety is caused due to unorganized emission of poisonous and harmful gases such as H2S and SO2 when the cover of the reaction furnace is opened for adding the coke raw materials and removing furnace slag, and clean production and continuous production are realized.

Description

technical field [0001] The invention belongs to the technical field of carbon disulfide coke production technology, and in particular relates to a carbon disulfide coke continuous production process and device. Background technique [0002] The existing carbon disulfide coke method intermittent production process includes: raw material pretreatment (carbon drying and sulfur melting) - synthesis reaction - desulfurization - condensation - rectification purification - Claus furnace tail gas treatment and other six processes, due to the synthesis reaction process , when the gasification reaction furnace is opened to add coke raw materials, the addition of sulfur raw materials needs to be stopped (coke raw materials need to be added once a day, because when the furnace cover is opened for feeding, H 2 S, SO 2 The unorganized discharge of toxic and harmful gases has brought environmental and safety hazards. In actual operation, in order to reduce the hazards, it is necessary to ...

AI Technical Summary

Problems solved by technology

[0003] In summary, the problem with the batch production method of the carbon disulfide coke method is that when the reactor furnace is opened and the coke raw material is added, the H 2 S, SO 2 The unorganized discharge of toxic and harmful gases has brought certain environmental and safety hazards.

[0004] In addition, the above-mentioned carbon disulfide coke method intermittent production method also has some H 2 S, SO 2 The unorganized discharge of toxic and harmful gases has also brought certain environmental and safety hazards.
