Automatic mixing system and method based on micro-interface mixing tank

Abstract

The invention provides an automatic mixing system based on a micro-interface mixing tank. The automatic mixing system comprises a reaction tank, wherein the side wall of the reaction tank is provided with a detection port, and the detection port is connected with an automatic control system; a defoaming agent opening is formed in the top of the reaction tank and is connected with the automatic control system; and a stirring device is arranged at the bottom of the reaction tank, a micro-interface generator is arranged above the stirring device, and the micro-interface generator is connected with an air inlet for crushing and dispersing air. The reaction system is based on a micro-interface reaction technology, a gas-phase material and inert gas are crushed into micron-sized bubbles through a micro-interface, and the micron-sized bubbles are dispersed into a solution to form a micro-interface system, so reaction temperature, reaction pressure and the use amount of a catalyst can be reduced, and reaction efficiency is improved; and a reaction process is controlled by the automatic control system.

Description

technical field [0001] The invention relates to mixing in the chemical preparation industry, in particular to an automatic mixing system based on a micro-interface mixing tank and a method thereof. Background technique [0002] The mixing system is a very widely used mechanical equipment, which is widely used in chemical preparation, pharmaceutical, resin, food and construction industries. The main function of the mixing system is to mix different raw materials evenly to facilitate chemical reactions with higher efficiency or better physical properties. [0003] At present, the agitating blade mixing system is a relatively common mixing system. For example, in the hydrogenation reaction, the hydrogen is sheared and broken into fine bubbles by the agitating blades, which increases the gas-liquid mass transfer area to a certain extent. One or more stirring The blades rotate continuously to stir the materials in the reactor so that the mixture is evenly mixed. [0004] Howeve...

AI Technical Summary

Problems solved by technology

[0004] However, in the existing gas-liquid mixing system, the gas is difficult to be completely crushed and dispersed, the mass transfer area of ​​the phase boundary between the gas phase material and the liquid phase material is small, and the utilization rate of the gas is low, resulting in a large amount of gas and a high reaction temperature required for the reaction. and larger reaction pressure, and the temperature, pressure and other parameters in the mixing tank cannot be observed in real time in the prior art, and the parameters in the mixing tank cannot be adjusted in real time, which will affect the reaction and may cause danger in severe cases
