Pipe shell heat exchanger having heat exchange tube embedded with spring

Abstract

The invention relates to a shell-and-tube heat exchanger, particularly an internal spring type shell-and-tube heat exchanger with a heat exchange pipe. The heat exchanger adopts an insert perturbation enhancing technology to enhance perturbation heat transfer enhancement, and comprises a casing, an upper sealing head, a lower sealing head, a tube plate and a heat exchange pipe, wherein, the two ends of the casing are connected with the upper sealing head and the lower sealing head through the tube plate respectively; and the upper end and the lower end of the heat exchange pipe are fixed on the tube plate respectively. The heat exchanger is characterized in that a spring which is arranged in the center of the heat exchange pipe is arranged in the heat exchange pipe; and one end of the spring is fixed on a spring suspension frame which is arranged on the end surface of the water inlet of the heat exchange pipe, and the other end thereof which is a free end is put near the water outlet of the heat exchange pipe. The heat exchanger has the main advantages as follows: by simply carrying out the structural improvement of a common shell-and-tube heat exchanger, the effects of heat transferring and de-scaling are better enhanced without additional energy supply; the structure is simple; and the installation is convenient.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to a shell-and-tube heat exchanger with a built-in spring in a heat exchange tube, which enhances the disturbance-enhanced heat transfer through the insert disturbance enhancement technology. Background technique [0002] In current industrial production, various heat exchangers are widely used for heat exchange, among which shell-and-tube heat exchangers are the most commonly used. In order to improve the heat transfer coefficient of the heat exchanger, scientific and technological workers have carried out research on surface structure strengthening, insert disturbance strengthening, vibration strengthening, etc. Among them, insert reinforcement is mainly inserted ribbons, most of which are The pulsating pressure in the flow cannot be effectively utilized, and the problem of fouling remains unresolved.
