Reactor for synthesizing vinyl chloride through acetylene method

Abstract

The invention discloses a reactor for synthesizing vinyl chloride through an acetylene method. The reactor comprises a reactor body, a reaction mechanism and a cooling mechanism; an air inlet and an air outlet are formed in the reactor body; the reaction mechanism is arranged inside the reactor body; the cooling mechanism is further arranged on the reactor body; the reactor body is formed by connecting an upper shell, a barrel and a lower shell; the upper shell, the barrel and the lower shell are sequentially connected from top to bottom. The reactor is characterized in that the cooling mechanism is located between the reactor body and the reaction mechanism; a rotating device is further connected to the reaction mechanism. By improving the structure of the reactor, the cooling effect and anti-corrosive performance of the reactor for synthesizing the vinyl chloride through the acetylene method are good, the synthesis efficiency of the vinyl chloride is high, and the synthesis effect of the vinyl chloride is good; the reactor is simple in structure, convenient and rapid to install and capable of further exerting advantages during synthesis reaction of the vinyl chloride through the acetylene method in a fixed-bed reactor.

Description

technical field [0001] The invention relates to a reactor in the field of chemical equipment, in particular to a reactor for synthesizing vinyl chloride by an acetylene method. Background technique [0002] Chemical reactor is the core equipment of chemical production. The advanced level of its technology has an important impact on chemical production and directly affects the investment scale and production cost of the device. It is also the heart of the chemical production process, from raw materials through reactors to our desired products. [0003] Chemical reactors mainly include tubular reactors, tank reactors, reactors with a bed of solid particles and tower reactors. Among them, the tank reactor is composed of a cylindrical container with a relatively small length and diameter, and is often equipped with a mechanical stirring or airflow stirring device, which can be used for liquid-phase single-phase reaction processes and liquid-liquid phases, gas-liquid phases, gas...

AI Technical Summary

Problems solved by technology

[0005] At present, in the synthesis of vinyl chloride from acetylene, fixed-bed reactors have certain advantages over fluidized beds due to their small backmixing, low catalyst mechanical loss, and simple structure, but their heat transfer is poor. The process of synthesizing vinyl chloride from acetylene is as follows: Exothermic reaction, the heat of reaction is very large, even the tube-and-tube reactor may have a runaway temperature, that is, the reaction temperature is out of control and rises sharply, exceeding the allowable range, which affects the synthesis effect; and the catalyst is generally not replaceable after it is worn out during the operation Or supplement, and the requirements for the corrosion resistance of the reactor are relatively high, all of which are the reasons for the low synthesis efficiency of vinyl chloride in the reactor and the poor synthesis effect of vinyl chloride
