Abstract

The CS2 reactor furnace includes inner furnace body of refractory material, outer furnace body of refractory material, and heating chamber between the inner surface body and the outer furnace body. In the peripheral of the inner surface body, there are sulfur gasifying furnace and carbon material preheating furnace, and the sulfur gasifying, furnace is connected via sulfur vapor duct to the bottom of the inner furnace body. The CS2 reactor furnace of the present invention has no sulfurizing and oxidizing corrosion of inner furnace body and thus long service life. The material preheating speeds the reaction and raise the product yield. Heating the coal-burning gas furnace via the main fire channel communicated with the furnace body can save fuel and stabilize furnace temperature.

Description

technical field [0001] The invention relates to a carbon disulfide production plant and the construction of the plant. Background technique [0002] In the prior art, there are mainly two kinds of reaction equipment for producing carbon disulfide by using solid carbon: ordinary reaction furnace and split type reaction furnace. The ordinary reaction furnace is also the traditional carbon disulfide reaction retort. It preheats the charcoal and puts it into the reaction furnace, then heats and liquefies the solid sulfur and passes it into the bottom of the reaction furnace, and continues to heat in the reaction furnace to the reaction temperature to promote sulfur and carbon. The reaction produces carbon disulfide, and charcoal or sulfur is added depending on the reaction during the reaction. Since the reaction to produce carbon disulfide must be carried out under airtight conditions, one is to maintain the furnace temperature; the other is to prevent gas leakage. And every t...
