Problems solved by technology

[0008] In order to ensure that the amount of carbon prepared meets the needs and efficiency of production, the inner chamber of the combustion furnace is generally larger. Black carbon or semi-coke in the inner chamber of the vertical barrel-shaped combustion furnace will often be heated unevenly due to uneven ventilation, and the ventilation is good. The charcoal preparation has been overheated, semi-coke is brittle, and a large amount of invalid powder is produced, resulting in increased loss. The ineffective powder entering the reactor will also hinder the normal progress of the reaction and increase the amount of slag, reducing production efficiency; If it is relativ

Abstract

The invention discloses a charcoal preparation method and a special charcoal preparation drying device during carbon disulfide production. The charcoal preparation method and the special charcoal preparation drying device during carbon disulfide production are characterized in that black charcoal or semi-coke serves as raw materials, and the raw materials are dried at the temperature of 350-450 DEG C; the charcoal preparation drying device comprises a drying chamber (18) composed of a shell (13); a heating interlayer (10) is arranged on the periphery of the shell (13); a central drying air inlet mechanism is arranged in the center of the drying chamber. Compared with the prior art, the raw material consumption can be greatly reduced, and especially energy saving and environmental friendliness are further achieved.

Description

technical field [0001] The invention belongs to the technical field of carbon disulfide production, in particular to a method for preparing carbon during production of carbon disulfide and a special drying device for preparing carbon. Background technique [0002] At present, the methods for producing carbon disulfide mainly include charcoal sulfur method, semi-coke batch production method and natural gas method. [0003] The charcoal sulfur method has been eliminated by the state because it uses a lot of wood to burn charcoal and destroys forest resources. [0004] Due to the large one-time investment, high production cost, and the natural gas source, the natural gas method is currently only available in a few areas. [0005] The semi-coke production method mainly uses black carbon or semi-coke as the carbon raw material. This method has rich raw material resources, relatively simple equipment, and low investment. Therefore, the production cost is low and the product quali...
