Glass-lined reactor

Abstract

The invention discloses a glass-lined reactor, and belongs to the technical field of glass-lined reaction devices. The glass-lined reactor comprises a tank body, a tank cover, a steam inlet, a stirrer with stirring blades and a motor, wherein the motor is connected with the stirrer, a thermometer I penetrating the tank cover is vertically placed in the tank body, a steam outlet is formed in the tank body and is provided with a pressure gauge and an automatic pressure release valve, a thermometer II horizontally placed in the tank body is arranged on the lower portion of the tank body, the thermometer I and the thermometer II are placed on two sides of the stirrer respectively, and the thermometer II is placed above the stirring blades. The glass-lined reactor has the advantages of simple structure and capabilities of accurately controlling reaction temperature and pressure and reducing manpower.

Description

technical field [0001] The invention relates to a glass-lined reaction tank, which belongs to the technical field of glass-lined reaction devices. Background technique [0002] The glass-lined reaction tank equipment is to line the inner surface of the steel container with high-silica-containing glass, and firmly adhere to the metal surface after high-temperature burning. It is often used in petrochemical, rubber, pesticide, dyestuff, pharmaceutical and other industries to complete sulfonation, nitration, hydrogenation, alkylation, polymerization, condensation and other processes, as well as reaction equipment for many other processes of organic dyes and intermediates. In the prior art, there is only a thermometer inserted through the hole on the tank cover in the glass-lined reaction tank. Due to the limitation of the length of the thermometer and the structure of the tank, the configuration of this thermometer cannot accurately measure the reaction liquid in the reaction t...

AI Technical Summary

Problems solved by technology

In the prior art, there is only a thermometer inserted through the hole on the tank cover in the glass-lined reaction tank. Due to the limitation of the length of the thermometer and the structure of the tank, the configuration of this thermometer cannot accurately measure the reaction liquid in the reaction tank. When the reaction solution is less, the lower end of the thermometer cannot be submerged in the reaction solution, so the temperature of the reaction solution in the reaction tank cannot be measured.
