Embodiment Construction

[0038] Such as Figure 1-12 As shown, the self-cleaning in-tube self-cleaning enhanced heat transfer device of the present invention includes a plurality of rotating parts 2 arranged in the heat transfer tube 1, and a fixing frame 3 is provided at both ends of the heat transfer tube 1 through a socket connection. The support shaft 4 passing through the heat transfer tube 1 is fixedly supported on the frame 3, and the plurality of rotating parts 2 have a central hole 21 for the support shaft to pass through, and the diameter of the central hole 21 is slightly larger than the axis of the support shaft 4 diameter, so that the plurality of rotating parts 2 are rotatably supported on the support shaft 4, and at least between a pair of adjacent rotating parts 2, there is a limit separating the adjacent ends of the pair of rotating parts 2. Positioning member 5 , which is fixed on the support shaft 4 , and the limiting member 5 divides the plurality of rotating parts 2 into two or mo...

Abstract

A self-cleaning enhanced heat transfer device inside a tube comprises multiple rotary members (2) mounted inside a heat transfer tube (1). A fixing frame (3) is mounted at each end of the heat transfer tube (1). A supporting shaft (4) passes through the heat transfer tube (1) and the two ends of the supporting shaft (4) are fixed at the fixing frames (3). The rotary members (2) are pivotally mounted at the supporting shaft (4). A limiting member (5) is mounted between at least a pair of adjacent rotary members (2) for separating the ends of the adjacent rotary members (2).

Description

technical field [0001] The invention relates to a device for enhancing heat transfer and self-cleaning in the heat transfer tube of a shell-and-tube heat exchange equipment, and the device can be widely used in the tube and shell of thermal power generation, petrochemical, food, pharmaceutical, light industry, metallurgy, shipbuilding and other industries Type heat exchange equipment and reaction equipment, especially the self-cleaning enhanced heat transfer device in the tube that uses the fluid in the heat transfer tube as power and can perform enhanced heat transfer and online cleaning. Background technique [0002] The inner wall of the heat transfer tube of the shell-and-tube heat exchanger is prone to fouling after a period of use, and fouling will lead to a decrease in heat transfer efficiency and an increase in fluid flow resistance, thereby increasing energy costs and production costs of the enterprise, and even more serious It is the scaling that will also form cor...
