Abstract

The invention discloses a raw material heating system for preparing carbon disulfide, which is characterized by comprising a heating furnace body, a preheating pipeline, a heating pipeline and a raw material mixing device, wherein the preheating pipeline and the heating pipeline are arranged inside the furnace body, both ends of which penetrating out of the heating furnace body; an outlet of the preheating pipe and an inlet of the heating pipe communicate with the raw material mixing device respectively; and the raw material mixing device is further provided with a raw material inlet at the upper end. The system and process provided by the invention have the beneficial effects of sufficient mixing of raw materials, thorough heating of the raw materials, saving of the raw materials, improved reaction efficiency of the raw materials and increased yield of products.

Description

technical field [0001] The invention relates to a raw material heating system and process for preparing carbon disulfide. Background technique [0002] Carbon disulfide is an important raw material for the manufacture of viscose fiber and cellophane. One way to industrially prepare carbon disulfide is to catalyze the mixed raw materials of methane and sulfur by heating. In order to achieve a better reaction effect, the raw materials need to be mixed and preheated. The unreasonable layout of the heating tubes in the heating furnace in the prior art leads to an unsatisfactory heating effect on the raw material, which in turn leads to incomplete reaction of the raw material and waste of fuel. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a raw material heating system and process for producing carbon disulfide, which fully heats the raw material and saves fuel. [0004] To achieve the above obje...
