High pressure reactor

Abstract

The invention discloses a high pressure reactor, which comprises a reactor body. An electromagnetic heater is arranged at one side inside the reactor body. a refrigerator is arranged at the other sideinside the reactor body. A heat-insulation layer is arranged on the inner wall of the reactor body. The top of the outer side of the reactor body is provided with a raised ring. The top of the reactor body is provided with a reactor cover. A protective cover is arranged at the middle position of the top of the reactor cover. Through a first air-duct and a second air-duct, a buffer effect is achieved when switching between heating and cooling of the high pressure reactor. Thus, expansion and contraction of the high pressure reactor are avoided, explosion risk of the high pressure reactor is reduced, health and safety of workers are better guaranteed, and work efficiency is improved. Through a motor driving a first rotating shaft to rotate, stirring vanes are driven to stir reactants in thehigh pressure reactor and then the reaction effect of the reactants is better.

Description

technical field [0001] The invention relates to the field of chemical reaction vessels, in particular to a high-pressure reaction kettle. Background technique [0002] The broad understanding of the reaction kettle is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. [0003] However, the existing reactor generally heats and cools the outer jacket, which is difficult to realize in a short time when switching between heating and cooling, and suddenly cools the reactants in the reactor after heating, which will easily cause the reactor to heat up. Explosion occurs during cold shrinkage, which not only wastes the reactants, but also causes health hazards to the staff. Since the inside of the reactor is in a high-pressure environment when the reactor is working, the air cannot be replaced well, and the no...

[0003] However, the existing reactor generally heats and cools the outer jacket, which is difficult to realize in a short time when switching between heating and cooling, and suddenly cools the reactants in the reactor after heating, which will easily cause the reactor to heat up. Explosion occurs during cold shrinkage, which not only wastes the reactants, but also causes health hazards to the staff. Since the inside of the reactor is in a high-pressure environment when the reactor is working, the air cannot be replaced well, and the normal progress of the reaction cannot be ensured. The reaction kettle lacks stirring equipment when heating, so that the mixing effect of the reactants is not good
