Improved reaction and separation synchronous reactor

Abstract

The invention discloses an improved reaction and separation synchronous reactor. The improved reaction and separation synchronous reactor comprises a bubble gravity reaction tower or stirring reaction tower and a constant-temperature settling tower, and is mainly characterized in that the bubble gravity reaction tower or stirring reaction tower is connected with the constant-temperature settling tower through a flange, a micropore filter plate allowing liquid to pass through is arranged in the constant-temperature settling tower, and a circulating pipeline is arranged at the position, on the lower portion of the micropore filter plate, of the constant-temperature settling tower and connected with the upper portion of a reaction zone of the reaction tower. According to the improved multiphase reactor, overreaction of products in a reaction kettle can be reduced so as to obtain a product with higher purity, blockage of a connecting pipeline between the reaction kettle and the constant-temperature settling tower and the circulating pipeline can be prevented, and a liquid product and a solid product can be effectively separated in time on the premise of completing reaction. The improved multiphase reactor is especially suitable for reactions where the specific gravity of products is larger than that of reactants and the products are insoluble for one another and comprise solids.

Description

technical field [0001] The invention relates to an improved reaction separation synchronous reactor, which belongs to the technical field of reactors. Background technique [0002] In chemical production, a heterogeneous reaction system in which the specific gravity of the product is greater than that of the reactants and is incompatible with each other is often encountered. During the reaction process, gas, liquid and solid exist in the reaction system at the same time. For the reaction system where heterogeneous substances coexist, various types of reactor equipment currently used in chemical production, during the entire reaction period, the reactants and reaction products are naturally or forcedly stirred and distributed in the reaction zone. After the reaction is over, the reactant and the reaction product are moved to a separator for separation. Since the existence of multi-phase substances in the system will affect the fluidity of the liquid in the production device,...

AI Technical Summary

Problems solved by technology

However, it still does not solve the problem that the actual inner diameter of the connecting pipe between the reactor and the separator is continuously reduced due to the continuous growth of crystallization of the product on the inner wall, and the problem that the three-way switch of the connecting pipe is blocked

In addition, new problems have arisen, mainly because the liquid entering the external circulation pipe is a high-temperature supersaturated liquid containing solid components, and the high-temperature liquid precipitates solid substances through heat exchange with the environment during the external circulation process, which blocks the equipment. The external circulation system affects the continuous progress of the reaction and separation process
