Problems solved by technology

But now the general process is the reaction under the condition of venting, so a large amount of formic acid gas will volatilize into the surrounding environment during the reaction process, which will cause great harm to people and also cause great pollution to the environment.
And along with the volatilization of formic acid in the reaction process, the concentration of formic acid in the reaction system is reduced, which affects the reaction speed, increases the reaction time, and affects production efficiency. Moreover, formic acid is a substance with a pungent smell, and its smell seriously affects the working environment. , and formic acid is a flammable and explosive gas, which will cause unsafe factors in the workplace

Abstract

The invention discloses a condensed reflux device of an epoxy reactor. The device comprises a barrel-shaped reflux container, wherein a condensation pipe is assembled on the reflux container, one end of the reflux container is connected with a reflux pipe which extends into the reactor from the top of the epoxy reactor, and the other end of the reflux container is connected with a blow-down pipe. The device has the beneficial effects that volatile formic acid gas is condensed into liquid in the reflux container so as to reflow into the reactor again, so that formic acid in a reaction system cannot be reduced, the working environment cannot be influenced, and risks generated by the formic acid gas can also be avoided; moreover, the production efficiency and benefit are improved through using a condenser; and in addition, the working environment is purified, the danger coefficients of workshops are decreased, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to a condensation reflux device, in particular to a condensation reflux device of an epoxy reactor. Background technique [0002] In the epoxy reaction, formic acid or acetic acid is usually used as a catalyst, and formic acid is basically used, and its dosage accounts for about 5% of the oil. And formic acid is a kind of extremely volatile liquid, and has irritating smell, and its contact has certain influence to people's eyes, skin and respiratory tract, and it also has certain toxicity, and belongs to flammable and explosive gas. But now the general process is the reaction under the condition of venting, so a large amount of formic acid gas will volatilize into the surrounding environment during the reaction process, which will cause great harm to people and also cause great pollution to the environment. And along with the volatilization of formic acid in the reaction process, the concentration of formic acid in the reaction s...
