Normal pressure reaction kettle

Abstract

The invention relates to a normal pressure reaction kettle. The normal pressure reaction kettle comprises a kettle body, wherein the inner wall of the kettle body is provided with more than one spiral deflector; the top of the kettle body is provided with one through hole; the kettle body is internally provided with one drainage tube; one end of the drainage tube penetrates through the through hole to be connected with a vacuum tube and a discharge tube through a tee valve. The normal pressure reaction kettle has the beneficial effects that materials inside the kettle body can be mixed repeatedly in the spiral deflectors after being stirred by a stirring paddle, so that large turbulent flow is formed and the materials are mixed uniformly; the spiral deflectors are detachably fixed on the inner wall of the kettle body, and are convenient to clean and replace. When a reaction process is monitored on line, the materials are taken through the drainage tube conveniently, and the quantity of the taken materials is controllable, so that more materials are saved, and the yield is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment reactors, in particular to an atmospheric pressure reactor. Background technique [0002] Reactors are widely used in chemical, pharmaceutical, rubber, dye, food and other industries, and are mainly used to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes. In the process of using the reactor to operate the reaction, it is often necessary to continuously monitor the reaction process to control the various conditions of the reaction in order to better complete the reaction. Reactors in the prior art are generally provided with a kettle cover and a discharge port. When monitoring the reaction process, it is necessary to discharge and take materials by opening the kettle cover or opening the discharge port, and then send samples for analysis. Such an operation is cumbersome, and often takes too much material each time, causing u...

AI Technical Summary

Problems solved by technology

In this way, the method is cumbersome, and too much material is often taken each time, resulting in unnecessary waste. If during the reaction, frequent monitoring and too many times of material extraction will reduce the yield of the final product

[0003] In addition, when using a reactor for stirring, if the particles are too large or the solubility of the substance is not good, if the stirring paddle is used alone, the material will not be mixed uniformly.
