Abstract

The invention relates to a thermal compensation type jet reaction system which comprises a jet reactor, a working fluid and a driving fluid; the jet reactor comprises a device body and a nozzle, the device body is provided with a driving fluid inlet and a reactor outlet, the working fluid is jetted into the device body through the nozzle, and the driving fluid enters the device body through the driving fluid inlet; then the working fluid and the driving fluid are mixed under the action of jet entrainment and undergo an exothermic chemical reaction, wherein at least one of the working fluid andthe driving fluid undergoes a gasification process and gasification latent heat required by the gasification process is compensated by reaction heat of the exothermic chemical reaction; finally, thegasified and reacted materials are discharged from an outlet of the reactor. Through energy matching of phase change heat and reaction heat, system temperature rise caused by reaction heat release isreduced or avoided, optimal reaction temperature distribution is obtained, reaction effects such as reaction efficiency improvement, side reaction reduction and product yield improvement are improved,in-situ utilization of the reaction heat can be realized, and energy waste is avoided.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and relates to a thermal compensation injection reaction system, in particular to a thermal compensation injection reaction system for exothermic reaction. Background technique [0002] Exothermic chemical reactions are very common in the chemical industry, such as oxidation, nitration, fluorination, phosgenation, and diazotization. Such reactions usually have a fast reaction rate and require harsh heat removal capabilities of the reactor. If the equipment such as the kettle is not properly controlled, it is easy to cause overheating, material leakage, intensified side reactions and even explosions. [0003] As we all know, the ejector is powered by the pressurized working fluid, and uses the entrainment of the ejection fluid by the jet and the "mixed shock wave" to transfer energy and mass. It has the advantages of simple structure, high reliability, and good sealing. Advantages, when...
