Description

Technical Field

[0001] This utility model relates to the technical field of heat exchanger shell-side cleaning mechanisms, specifically heat exchanger shell-side cleaning mechanisms. Background Technology

[0002] A heat exchanger shell-side cleaning system is a cleaning device specifically designed for the shell side (i.e., the space between the tube bundle and the shell) of a shell-and-tube heat exchanger. It is used to remove dirt (such as scale, oil, microorganisms, etc.) that accumulates in the shell side during long-term operation, in order to restore the heat exchanger's heat exchange efficiency. The cleaning system typically includes a nozzle system with multiple nozzles or high-pressure water guns, a positioning system to ensure that the nozzles are accurately aligned with each channel, a delivery system for conveying the cleaning medium, and a waste liquid treatment system for collecting and treating the cleaning liquid. The shell side is cleaned using high-pressure water jets or chemical cleaning agents. High-pressure water jets generate high-speed water flow through nozzles to break up and wash away the dirt; chemical cleaning uses a circulating pump to circulate the cleaning agent within the shell side to dissolve or remove the dirt.

[0003] In the prior art, the heat exchanger shell-side cleaning mechanism moves on the support rail for easy and thorough cleaning of the heat exchanger shell side. The cleaning mechanism is fixed on the support rail by electric brake pads. However, the electric brake pads acting on the rail can easily wear down, reducing friction. When the cleaning mechanism is in use, the large flushing force can easily cause the cleaning mechanism to move, thus affecting the cleaning efficiency of the heat exchanger shell side.
