A split-type spiral coil heat exchanger

Abstract

The invention discloses a split-type spiral coil heat exchanger, which comprises several spiral coil heat exchange sleeve structures, and the several spiral coil heat exchange sleeve structures are all fixed on a support mechanism, and the adjacent The helically coiled heat exchange sleeve structure is connected through the pipe structure; each helically coiled heat exchange sleeve structure is composed of several layers of helically coiled heat exchange sleeves, and the heat exchange sleeves are arranged obliquely, including coaxial sleeves The inner pipe and the outer pipe, the inner pipe is connected with the inner pipe inlet pipe, and the outer pipe is connected with the outer pipe inlet pipe; The outer straight pipe is connected by several outer 90° elbow pipes. It solves the problem of difficult cleaning and maintenance in the heat exchange of fluids containing solids, salts, and organics that are easy to scale and block under high temperature and high pressure conditions, thereby ensuring the long-term, stable, and safe operation of the heat exchanger.

Description

technical field [0001] The invention relates to a detachable, cleanable and maintainable sleeve-and-tube heat exchanger used in the technical fields of energy, chemical industry, environmental protection, petroleum and metallurgy, in particular to a new type of split-type spiral coil heat exchanger that can be cleaned and maintained. Tube heat exchanger. Background technique [0002] In energy, chemical, environmental protection and other industries, heat exchangers are one of the important equipment. Many materials in the production process have complex and diverse components. For example, sewage and waste in sewage treatment contain a large amount of organic matter, inorganic salts and solid particles, etc. It is easy to scale on the heated wall of the heat exchanger, thereby blocking the heat exchanger and affecting the efficiency and safety of equipment operation. As the main equipment in the field of chemical industry and environmental protection production, the operat...

AI Technical Summary

Problems solved by technology

However, common materials always contain a large amount of organic matter, inorganic salts, solid particles and other components that are easy to scale and deposit, resulting in silting and blockage of heat exchanger pipes, especially in areas where the flow rate decreases such as inner pipe bends and outer pipe connecting pipes.

Traditional casing heat exchangers are mainly horizontal bends, and they are always a whole, which is not conducive to cleaning and sewage discharge at the bends, incomplete operation, poor effect, and is not conducive to the dismantling and maintenance of local areas, especially For large heat exchanger equipment, the above problems are more prominent when cleaning, repairing or replacing parts
