A high conversion continuous flow reaction system

A high conversion continuous flow reaction system

The utility model patent belongs to the field of chemical equipment, and presents a high-conversion continuous flow reaction system, including a microchannel fast reactor and a buffer reactor, the microchannel fast reactor is provided with a microdistributor and a reaction tube, the microdistributor is provided with a material inlet and a flat cavity connected with the material inlet, and the flat cavity is connected with the reaction tube, and there is a hot and cold medium inlet and outlet on the microchannel fast reactor; the buffer reactor is provided with several heat exchanger mixing units, and the buffer reactor is provided with an inlet and outlet for the heat exchanger mixing units; the end of the reaction tube away from the microdistributor is connected to the buffer reactor housing. The utility model patent uses microchannel fast reactor to achieve rapid heat transfer, effectively reduced side reactions, and uses the buffer reactor to further carry out the material reaction, thus further improving the conversion rate and product yield.

Chemical reactor is a kind of equipment to realize the reaction process, it is widely used in chemical industry, oil refining, metallurgy, light industry and other fields. Chemical reactor is the core equipment of chemical production, and the advanced degree of its technology has an important impact on chemical production, which directly affects the investment scale and production cost of the plant.

 

At present, the reaction synthesis process usually adopts the kettle-type batch reaction, and the mass and heat transfer efficiency of the reaction materials is at a relatively low level, which is unfavourable to the chemical reaction. Especially for chemical reactions such as nitrification and ammoniation, which have fast reaction rate and high heat release, the traditional kettle and tubular reactors are difficult to transfer the heat generated during the reaction process in a timely manner, which leads to an increase in the number of side reactions, thus affecting the yield of the products and increasing the production cost.

 

The utility model patent belongs to the field of chemical equipment, especially relates to a high conversion rate continuous flow reaction system.
