Low-temperature reaction kettle cooling system with gas-containing reactants and use method of low-temperature reaction kettle cooling system

Abstract

The invention discloses a low-temperature reaction kettle cooling system with gas-containing reactants and a use method of the low-temperature reaction kettle cooling system, and relates to the technical field of chemical production. The low-temperature reaction kettle cooling system with the gas-containing reactants comprises a reaction kettle, a thermoelectric generator is arranged at the top of the reaction kettle, a heat conduction net is arranged in an inner cavity of the reaction kettle, the top end of the heat conduction net is connected with the input end of the thermoelectric generator, and an electric control valve is arranged on the right side of the reaction kettle in a penetrating mode. According to the low-temperature reaction kettle cooling system with the gas-containing reactants and the use method of the low-temperature reaction kettle cooling system, an independent control system is additionally arranged on the basis of the existing reaction kettle, internal cooling is achieved while the reaction effect is not affected negatively, meanwhile, the whole system is improved based on the existing reaction kettle, and therefore the existing reaction kettle does not need to be abandoned, expensive detection instruments are not needed, so that the improvement cost is reduced to a great extent.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a low-temperature reactor cooling system in which reactants contain gas and a method for using the same. Background technique [0002] The broad understanding of the reaction kettle is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. [0003] Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine and food. They are pressure vessels used to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes, such as reactors and reaction pots. , decomposition pot, polymerization kettle, etc.; materials generally include carbon-manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Mone...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a low-temperature reaction kettle cooling system with gas-containing reactants and its use method, which solves the problem that sometimes it is necessary to carry out a reaction with gas-containing reactants at low temperature in the existing reaction kettle. It is necessary to rely on an external cooling mechanism to cool down, and in order to ensure the safety of the reactor, most reactors often have thicker inner walls, making it difficult for the temperature to be introduced from the outside, so that the process requires higher energy consumption to ensure the temperature. , which increases the cost of production
