A self-rotating steel wire helix with hydrodynamic elastic deformation and energy storage

Abstract

The invention relates to a hydrodynamic elastic-deformation energy accumulation type rotating steel wire spiral. A steel wire spiral is installed in each heat exchange tube. When in operation, a hook head of the steel wire spiral rotates, a crank is obstructed by an elastic stop lever fixed on an orifice bearing bracket. After the elastic bending deformation generated by the obstruction gradually increases to a certain degree, the hook head crank can continue rotating after sliding over the elastic stop lever, thereby converting the original continuous rotation of the steel wire spiral into intermittent rotation. Since the proportion of non-rotation time is higher, the abrasion of the steel wire spiral, tube inner wall and bearing bracket can be controlled on a slight level, thereby satisfying the service life requirements for engineering; and meanwhile, the heat transfer reinforcement amplitude can be multiplied, the rotation start torque can be multiplied, and the rotation cleaning reliability can be enhanced. Compared with the prior art, the rotating steel wire spiral in the new structure does not increase the material consumption and manufacturing cost, has wide application range, and is especially suitable for shell and tube evaporators, film evaporators, reboilers, condensers, falling-film coolers and the like.

Description

technical field [0001] The patent of the present invention relates to a hydrodynamic elastic deformation energy storage self-rotating steel wire helix. It is suitable for all kinds of heat transfer equipment with shell and tube structure, such as evaporator, film evaporator, reboiler, condenser, falling film cooler, etc. Heat strengthening. Background technique [0002] Chinese patent ZL91213000.8 and literature (Experimental Research on Automatic Rotating Helical Heat Transfer Technology, Chemical Equipment Technology, 1997, N5, P4-8) reported a kind of steel wire helix in the heat transfer tube for descaling and anti-scaling and its heat transfer enhancement technology. Driven by the flow energy of the heat transfer liquid in the tube, the steel wire helix rotates by itself, scrapes the dirt on the inner wall of the tube, and has the function of online, automatic and continuous cleaning and anti-scaling; due to the diversion effect of the steel wire helix, the liquid in ...

Problems solved by technology

[0003] The purpose of the patent of this invention is to simultaneously solve the mutual wear problem between the existing self-rotating cleaning steel wire helix and the heat exchange tube wall, and the basic problem of self-rotating plastic-coated steel wire, and propose a hydrodynamic elastic deformation energy-storage self-rotating steel wire helix , through the elastic deformation mechanism to transform the steel wire spiral into intermittent rotation, the self-rotation cleaning speed and rotation time ratio of the steel wire spiral are greatly reduced to solve the problem of mutual wear between the steel wire spiral and the heat exchange tube wall, so there is no need for the steel wire spiral The plastic cladding naturally does not have the disadvantages of the plastic-coated steel wire helix, and in terms of the cost performance ratio between the heat transfer enhancement function and the fluid resistance, it is doubled compared with the existing self-rotating cleaning steel wire helix and the plastic-coated steel wire helix. Manufacturing The cost is still low and the scope of application is very wide
