Power moment strengthening technique for fixing device for rotary cleaning element removing dirt inside pipe

Abstract

A technique for increasing the kinetic moment of the fixed for the rotary washing part used to remove the dirt inside pipe features that the fluid coming in pipe flows through the reverse spiral channed at the entrance of heat transfer pipe to become a large-radius high-speed cyclone stream to directly flush the kinetic wheel, so generating a large kinetic moment.

Description

technical field

[0001] The invention relates to a dynamic torque strengthening technology of a fixing device for a rotating dirt cleaning part in a pipe. It can be applied to on-line rotary cleaning and anti-scaling and heat transfer enhancement of various shell and tube heat transfer equipment (such as heat exchangers, condensers, evaporators, etc.). Background technique

[0002] French patent (FR25545209 and Chinese patent (CN2465140Y, CN2413319Y) and other disclosed technologies for cleaning the dirt in the heat transfer tube and the rotary twisted belt cleaning technology, the axial fixation of the rotary twisted belt is sliding friction, and its frictional resistance torque is relatively large, and the spiral twisted belt The smaller the pitch, the greater the axial force that the helical twisted belt bears, and the greater the corresponding frictional resistance moment, which is exactly the opposite of the heat transfer effect of the helical twisted belt, which is the ...
