Chlorination reaction device

Abstract

The invention relates to a chlorination reaction device adopting the following technical scheme: the chlorination reaction device is composed of an injection mixer, an inner draft tube and a chlorination reactor, wherein the injection mixer is connected with the chlorination reactor, and the inner draft tube is arranged in the chlorination reactor; the injection mixer is characterized in that a material cavity is composed of a chlorination inlet pipe, a flat cover, a cylinder body, a nozzle and a mixed gas inlet pipe, a short section is respectively connected with the cylinder body and a reducer section which is connected with an injecting pipe, and the injecting pipe passes through the chlorination reactor to extend into the inner draft tube; the inner draft tube comprises a tube body, areinforcing rib, a supporting plate, a lifting lug and a stop block; the inner draft tube is matched with the chlorination reactor by the supporting plate and the stop block; the chlorination reactoris characterized in that an end socket and the cylinder body form a device body, the lower end of the cylinder body is provided with a man hole, a connecting plate and the supporting plate are used for fixing and limiting the inner draft tube, and the cylinder body is provided with a temperature measuring port, a material outlet and a support. The invention has favourable energy saving and loss reduction and obvious environment protection effect, and the production scale of carbon tetrachloride can be controlled from around 40% at present to 2%.

Description

technical field [0001] The invention relates to a chlorination reaction device, which is mainly used for reacting monochloromethane and chlorine under the action of a catalyst in the chlorination reaction device to generate a methane chloride mixture containing hydrogen chloride. Background technique [0002] The most advanced methane chloride production technology in the world is the methanol method. The chlorination reaction device is the core equipment in the methanol production process, and it is the reaction device for the low-temperature liquid-phase catalytic chlorination of monochloromethane in the production process. In the 1950s, there were only acetaldehyde and chlorine oil as raw materials for the production of chloroform and carbon disulfide as raw materials for the production of carbon tetrachloride. The production scale was small and the technology was backward. In recent years, domestic enterprises have introduced foreign advanced technology and scientific a...
