Abstract

The invention relates to a high-efficiency shell-and-tube heat exchanger which comprises a shell and a material tube, wherein the shell is wrapped on the outer side of the material tube, a closed shell pass is formed between the outer wall of the material tube and the inner wall of the shell, a tube pass is arranged in the material tube, two ends of the material tube extend out of the shell to form a material inlet and a material outlet, the upper end and the lower end of the shell are respectively provided with a heat source inlet and a heat source outlet which are communicated with the shell pass, the outer side of the material tube is provided with a continuous spiral groove, a continuous metal corrugated tube is embedded in the groove, and two ends of the metal corrugated tube. The shell pass is replaced by the metal corrugated pipe, and the plurality of metal corrugated pipes are wound on the outer wall of the tube pass, so that the flowing time of a heat exchange medium in the shell pass is prolonged, and the heat exchange is more sufficient; meanwhile, the continuous spiral groove is processed on the outer wall of the material pipe, and the metal corrugated pipe is embedded in the groove, so that the contact area between the metal corrugated pipe and the material pipe is increased, and sufficient heat exchange is facilitated.

Description

High-efficient shell and tube heat exchanger

Technical Field

The invention relates to a heat exchanger, in particular to a high-efficiency shell-and-tube heat exchanger.

Background

Among the existing heat exchangers, the shell-and-tube heat exchanger has the widest application range. The dividing wall type heat exchanger takes the wall surface of the tube bundle sealed in the shell as a heat transfer surface. The heat exchanger has the advantages of simple structure and reliable operation. In the shell-and-tube heat exchanger, one of a tube side and a shell side is filled with a heat exchange medium, and the other is filled with a product to be heat exchanged, and the two are indirectly contacted to realize heat exchange. The existing shell-and-tube heat exchanger has the defects that the tube pass and the shell pass are short due to the limitation of the space of the heat exchanger, the heat exchange time is insufficient, and the utilization or the recovery of heat is insufficient.

Disclosure of Invention

The invention aims to provide an efficient shell-and-tube heat exchanger which is long in heat exchange time and sufficient in heat exchange.

In order to achieve the above purposes, the technical scheme adopted by the invention is as follows:

the utility model provides a high-efficient shell and tube type heat exchanger, includes casing and material pipe, the casing wraps up in the material outside of tubes, forms airtight shell side between material outer wall of tubes and casing inner wall, is the tube side in the material pipe, the both ends of material pipe stretch out the casing and form material import and material export, the upper and lower end of casing is equipped with the heat source import and the heat source export of UNICOM shell side respectively, its characterized in that, the outside of material pipe is equipped with continuous heliciform recess, the recess is embedded to have continuous corrugated metal pipe, heat source import and heat source export are connected respectively to corrugated metal pipe's both ends.

Furthermore, more than one metal corrugated pipe is wound on the outer wall of the material pipe.

After the technical scheme is adopted, the invention has the beneficial effects that: in order to solve the problems of short heat exchange time and insufficient heat exchange of a heat exchange medium, the shell pass is replaced by the metal corrugated pipes, and the plurality of metal corrugated pipes are wound on the outer wall of the tube pass, so that the flowing time of the heat exchange medium in the shell pass is prolonged, and the heat exchange is more sufficient; meanwhile, the continuous spiral groove is processed on the outer wall of the material pipe, and the metal corrugated pipe is embedded in the groove, so that the contact area between the metal corrugated pipe and the material pipe is increased, and sufficient heat exchange is facilitated.
