Description

Technical Field

[0001] The utility model relates to the technical field of chemical reaction devices, and more specifically to a high-pressure reaction kettle with double coils and efficient temperature control. Background Art

[0002] Reactors are common chemical reaction equipment in the chemical industry, used to withstand high temperature, high pressure and other conditions in chemical reactions. In the reactor, chemical substances will undergo chemical reactions and produce by-products such as gas or liquid. High-pressure reactors are suitable for chemical reactions of high-temperature, high-pressure, high-vacuum, flammable, explosive, and highly toxic media. They can be designed according to the different process requirements of users and can be equipped with various materials. They can be designed with pressurized feeding, lower discharge, remote pressure transmission and other functions. They are mainly distributed in the fields of petrochemicals, chemistry, pharmaceuticals, polymer synthesis, metallurgy, etc.

[0003] The existing patent publication number: CN108654534B, discloses a double-coil energy-saving and high-efficiency reactor, whose structure includes a reactor body, an upper coil, a lower coil, a jacket, a stirring paddle, a baffle, etc. The upper coil and the lower coil are optimized in size and structure, and the structure of the stirring paddle and the baffle design are combined to form a good axial and radial flow of the material in the reactor body, and form turbulence near the coil, which effectively improves the uniformity of heating the material and greatly improves the heat exchange efficiency. The mixed heating method of the upper coil, the lower coil and the jacket can effectively utilize waste steam for the insulation, heating and evaporation of the material. The working method is flexible and has a significant energy-saving effect. At the same time, it greatly reduces the emission of waste steam and has a significant environmental protection effect.
