Rigid-connection enhanced heat transfer device

Abstract

The invention relates to a rigid-connection enhanced heat transfer device, comprising a heat transfer pipe, wherein the heat transfer pipe is internally provided with a plurality of rigid support shafts; the heat transfer pipe is fixedly connected with the rigid support shaft at the inner end of the heat transfer pipe by pendants; adjacent rigid support shafts in the heat transfer pipe are connected by rigid support strips; rotors are arranged on the rigid support shafts; the rotors can rotate on the rigid support shafts in the heat transfer pipe; and the axial lines of the rigid support shafts and the rotors and the axial line of the heat transfer pipe are in the same line. According to the invention, the pendants, the connection support strips and a support frame ensure the axial line of the rigid support shafts to be consistent with the axial line of the heat transfer pipe, so that the rotors on the rigid support shafts can be maintained at the center of the heat transfer pipe, andthe rotors do not contact the wall of he heat transfer pipe, thereby preventing the rotors and the heat transfer pipe from being abraded, and prolonging the service life of the device and the servicelife of the heat transfer pipe; Moreover, the rigid support shafts and the pendants are in threaded connection, which facilitates installation and maintenance; and the device has the advantages of compact structure, reduced water resistance and enhanced heat transfer effect and is safe and reliable.

Description

technical field [0001] The invention relates to a heat transfer device, in particular to a rigid connection enhanced heat transfer device, which belongs to the technical field of heat transfer tube inserts. Background technique [0002] A large number of heat exchangers are used in industry, among which shell-and-tube heat exchangers are used the most, but fouling on the inner wall of heat transfer tubes of shell-and-tube heat exchangers is common. Heat transfer efficiency, and there are safety hazards, so people have been looking for a device that can solve the fouling of the pipe wall and increase the heat transfer efficiency. Among the existing enhanced heat transfer methods, the rotor type enhanced heat transfer device has a certain effect of enhanced heat transfer and cleaning. The support tube is composed of a support tube. The fixed frame is installed at both ends of the heat transfer tube. The steel wire rope is fixed on the fixed frame through the shaft hole of the...

AI Technical Summary

Problems solved by technology

[0003] The device mentioned in the above patent has the effect of descaling and enhancing heat transfer, but in actual application, since the central axis is a steel wire rope, a certain amount of deflection will be generated when both ends are fixed, and a considerable part of the device in the heat transfer tube is connected to the tube wall. In direct contact, when the device works in the heat transfer tube, the rotation of the rotor worn on the steel wire rope will wear the tube wall; since the central axis is a whole steel wire rope, the steel wire rope is riveted on the fixed frame with a support tube, when heat transfer When the device in the tube is damaged, it cannot be repaired
