Description

Technical Field

[0001] The utility model relates to the technical field of silicon carbide heat exchangers, in particular to a sealing structure for silicon carbide heat exchangers. Background Art

[0002] Silicon carbide heat exchanger uses silicon carbide material as heat transfer element, which is suitable for extreme environments such as high temperature, high pressure, strong corrosion, high wear, etc. in chemical, petroleum, pharmaceutical, metallurgical and other industries. Its excellent heat exchange efficiency can meet the urgent needs of energy conservation, emission reduction and environmental protection; silicon carbide material has extremely high corrosion resistance, oxidation resistance and corrosion resistance.

[0003] For example, announcement number CN217303656U discloses an anti-corrosion lining of a shell-and-tube silicon carbide high-temperature heat exchanger, a thermal compensation structure at the end of the heat pipe and a cavity anti-corrosion structure arranged inside the cavity. Since the floating blocks can slide relative to each other, when the heat pipe is heated and extended along the axial direction, its end slides with the floating block. When the heat pipe cools and shrinks, it is reset under the action of the elastic block to form thermal compensation for the heat pipe; the anti-corrosion sealing structure between the heat pipe and the floating block effectively prevents gas leakage; the cavity anti-corrosion structure and the flange anti-corrosion structure effectively protect the inside of the cavity, and the cavity anti-corrosion structure has radial elasticity with the help of a skeleton and a woven mesh.

[0004] The above-mentioned existing technology completes the elastic protection of the sealing structure, but the elastic protection is uncontrollable, making it difficult to quickly know and respond when a failure occurs. At the same time, for heat exchange efficiency, it is impossible to achieve autonomous control of the heat conversion rate, which is not conducive to regulation and control in production use.
