Compound connecting structure for tube plate and external glass lining tube

Abstract

The invention relates to a compound connecting structure for a tube plate and an external glass lining tube. A first mounting hole is formed on an external tube plate; a second mounting hole is formed on a base plate; the left end of a heat exchange tube is inserted into the first mounting hole of the external tube plate; the heat exchange tube and the external tube plate are integrally welded in the position of the left end of the first mounting hole; the heat exchange tube on the right side of the external tube plate is inserted into the second mounting hole of the base plate; protecting layers are arranged on an inner wall position of the second mounting hole and a right side wall of the base plate; and a glass lining layer is arranged on the outer wall of the heat exchange tube on the right side of the external tube plate. The compound connecting structure for the tube plate and the external glass lining tube is high in strength, high in loading capacity, leakage-free, free from porcelain dropping phenomenon caused by stress concentration, and reliable and safe in use. After the compound connecting structure for the tube plate and the external glass lining tube is applied to glass lining equipment, the chemical industry production is boosted, the production capacity is increased, the economic benefit is increased, the equipment investment is reduced, the energy is saved, the consumption is reduced and the risk is reduced.

Description

technical field [0001] The invention relates to the technical field of glass-lined equipment, in particular to a multiple connection structure of a tube plate and an outer glass-lined tube. Background technique [0002] Heat exchanger is a general-purpose equipment widely used in chemical industry, medicine, pesticide, biochemistry, electronics, atomic energy and many other departments. It is inseparable from heating, cooling, evaporation, condensation and other processes in production. In the heat exchanger equipment, the most common application is the shell-and-tube heat exchanger, which has a simple structure, strong adaptability, and easy cleaning, and plays an important role in reducing consumption and improving production capacity. It is regarded as a Traditional standard heat exchangers are widely used in many industrial production departments. [0003] Glass-lined tube heat exchanger is one of the majority of shell and tube heat exchangers, because it has excellent ...

AI Technical Summary

Problems solved by technology

Although many units have always attached great importance to it, and invested a lot of manpower, material resources and a lot of time to study, it is still fragile, easy to remove porcelain, and easy to leak. Its service life is short and its reliability is poor. There is no safety guarantee in the process of production and use, which makes it difficult to manufacture glass-lined tubular heat exchangers, and its use is almost blank

[0005] The connection structure between the tube sheet and the glass-lined tube is a prominent problem, which seriously restricts the development of the glass-lined tube heat exchanger and its application in various industries.
