Problems solved by technology

[0004] At present, there have been many designs and manufactures for microchannel reactors in China. The designed microchannel reactors have more advantages than reactors, but the existing microchannel reactors have the following disadvantages: 1. After the existing microchannel reactor is fed with two or more reaction fluids, it is often accompanied by solid particle products during the reaction, and this solid particle product is easy to block the reaction microchannel, and the solid particles are often mixed into the final output reaction 2. Part of the reaction needs to add catalyst, but the microchannel size of the existing microchannel reactor is small, it is not easy to add catalyst, thus affecting its application

Abstract

The invention relates to the technical field of fine chemical engineering and discloses a microreactor. The microreactor comprises a microreactor body, wherein a micro-channel is formed in the micro-reactor body; the micro-channel is provided with a liquid inlet and a liquid outlet; an accommodating layer made of a porous material is embedded in the bottom wall of the micro-channel and can well accommodate solid particles generated by a reaction, so blockage of the micro-channel can be avoided; and the solid particles can be prevented from being mixed into a finally-flowing-out fluid, and fora reaction needing the addition of a catalyst, the catalyst can be placed in the accommodating layer in advance, thereby increasing a chemical reaction rate. The invention further discloses a manufacturing method of the microreactor. The microreactor is prepared through 3D printing. The microreactor having a three-dimensional structure and made of a metal material is rapidly constructed through the 3D printing technology; and operation is easy, speed is high, and industrialization is easy.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a microreactor and a manufacturing method thereof. Background technique [0002] Traditional tank-type mixing reactors are usually composed of tank body, heat transfer, transmission, stirring and sealing, etc., which are bulky and have a large amount of raw materials added at one time. Usually, due to the large addition of one-time raw materials, the added materials contain flammable, explosive, poisonous, corrosive media, etc., which will endanger personal and property safety to varying degrees, so the reactor is a very dangerous Sexual chemical equipment. According to statistics, there are more than 40 major safety accidents related to chemical reactors in China every year. In addition, due to the large addition of one-time raw materials, the reaction is difficult to accurately control, which will affect the product quality. Therefore, there is an urgent need for an e...
