A kind of carbon disulfide production equipment and production method

Abstract

The invention discloses a carbon disulfide production equipment and a production method, comprising a reaction furnace, four hot blast stoves located on the left and right sides of the reaction furnace, each hot blast stove is connected to the reaction furnace through a hot blast air distribution pipe, and the hot blast stoves on the left and right sides are connected to the reaction furnace. The air distribution pipes are arranged horizontally and symmetrically. A gas check device, a pressure detection device and a gas detection device are arranged at the outlet header of each hot blast stove. When the outlet pressure of the hot blast stove is equal to or lower than the pressure of the reaction furnace, the non-return device can be closed in time. , to prevent the gas in the reaction furnace from back channeling, the gas detection device detects the gas content in the hot air, and adjusts the air supply volume of the fan in time according to the level of the content. The gasification of raw materials, sulfur and chemical reactions combined with other raw materials, and the use of zonal distribution to maximize the reaction efficiency and utilization.

Description

technical field [0001] The invention relates to the technical field of chemical production and preparation, in particular to a carbon disulfide production equipment and a production method. Background technique [0002] Carbon disulfide is an important chemical raw material and a good solvent that cannot be replaced for a long time. It is widely used in rayon, cellophane, chemicals, pesticides, rubber, metallurgy, oil refining and other industrial sectors. Existing carbon disulfide production technologies use indirect heating (thermal radiation) to heat coke or other raw materials, which is a great waste of chemical resources. [0003] The natural gas method uses natural gas and sulfur as raw materials to produce CS2, adopts a tubular reaction, and uses natural gas as a heat source to heat the reaction tube (indirect heating by radiating methane gas at high temperature on the tube wall), the temperature is 600℃-800℃, and the high pressure (1.0MPa-2 Natural gas (methane) and...

AI Technical Summary

Problems solved by technology

[0005] At present, there are also internal heating type reactors such as: Li Huaiyi's "Resistance Type Internal Heating Semi-coke Carbon Disulfide Reactor" (application number 201820807887.9), but there are still no application examples, and it is still something on paper

The reaction furnace relies on the built-in resistance wire for heating, and the heating is uneven, and the protection device of the resistance wire is easily damaged under the long-term erosion of the carbon layer, which in turn causes damage to the resistance wire, and it is difficult to replace the resistance wire after damage
