Abstract

The invention discloses an automatic cleaning technology for a plastic double-helix link. The automatic cleaning technology is characterized in that an automatic cleaning mechanism is composed of theplastic double-helix link, an inclined end face bearing and a hook head shaft; and the plastic double-helix link is composed of a plastic double helix and a plastic link body, wherein the plastic double helix is the most important part for directly implementing the automatic cleaning function, and is also a part for providing part of automatic cleaning power or a convective heat transfer strengthening part for directly disturbing a boundary layer. According to the plastic for manufacturing the double-helix link, a material with the hardness remarkably larger than that of cleaned hard scale andthe density as high as possible needs to be selected as a filling agent of the plastic, so that the self-weight pressure of the plastic reaches a value required by the automatic hard scale cleaning strength; and the rotation speed is controlled to be about 100 revolutions per minute according to the inclined height difference of the inclined end face bearing. The technology is easy and convenientto manufacture, install and maintain, low in cost and suitable for automatic cleaning and convective heat transfer enhancement of a horizontal shell-and-tube heat exchanger with hard scale.

Description

technical field [0001] The invention relates to an automatic cleaning technology for plastic double-helix bonds in heat exchange tubes, which is mainly suitable for horizontal tube heat exchangers with hard scale (such as calcium-magnesium hard-scale water coolers, condensers, heat exchangers for variable temperature crystallization process, etc.) etc.) automatic cleaning and convective heat transfer enhancement. For example, horizontal condensers for various products in the petrochemical industry and organic synthesis industrial distillation towers (rectification towers), horizontal tube and tube heat exchangers for concentrated crystallization and variable temperature crystallization processes, especially the cooling water hardness is high, but for high Energy saving and efficiency enhancement of steam turbine vacuum condensers with high cleanliness requirements. Background technique [0002] Chinese Patent ZL95110822.8 (Efficient heat transfer equipment with self-rotatin...
