Multistage internal circulation reactor for chemical industry

Abstract

The invention relates to a multistage internal circulation reactor for the chemical industry and belongs to the technical field of chemical industrial equipment. The multistage internal circulation reactor for the chemical industry comprises a multistage reactor, a reaction chamber and a collector, wherein the multistage reactor is connected with a recoverer which comprises a casing and a sealing head, supporting legs are mounted at the lower end of the casing, a reflux control system is arranged on the multistage reactor, the reaction chamber is mounted at the top of the multistage reactor and directly connected with the multistage reactor, a discharge port is formed in the position, close to two side plates, of the bottom of the reaction chamber, and the collector is communicated with the reaction chamber through a connection pipe. The multistage internal circulation reactor has the benefits as follows: the pipeline is simple, pipe resistance is little, the vacuum degree of the system is high, the loss of pipes is little, operation is simple and convenient, the reaction rate is high, the effective volume of the reactor is large, a reaction can be performed more completely, and accordingly discharge of sewage is reduced.

Description

technical field [0001] The invention relates to a multi-stage internal circulation reactor for chemical industry, which belongs to the technical field of chemical equipment. Background technique [0002] Since the internal circulation reactor was first used, it has been recognized as having the characteristics of high load rate, large height-to-diameter ratio, small footprint, low infrastructure investment, and stable performance, and is therefore generally recognized by the chemical industry. However, the existing The internal circulation reactor also has problems such as low reaction rate and small effective volume of the reactor, and produces more waste water, which pollutes the environment and brings many problems to production and life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-stage internal circulation reactor for chemical industry, which has simple structure, convenient operation, improved r...
