Cleaning method for energy mixing heat exchange unit with water quality detection function

Abstract

The invention discloses a cleaning method for an energy mixing heat exchange unit with a water quality detection function. The energy mixing heat exchange unit comprises a secondary side heat exchanger and an energy mixing device connected with the secondary side heat exchanger in parallel. The cleaning method includes the following steps that the water cycle between the heat exchange unit and theoutside is cut off, a water body is pressurized, and the inner cycle is formed between the secondary side heat exchanger and the energy mixing device; a cleaning medicament is added in the energy mixing device; after the inner cycle is used for flushing the secondary side heat exchanger and the energy mixing device by certain time, the water quality is detected; if the water quality reaches the standard, water in the energy mixing device and the secondary heat exchanger is thoroughly discharged, and the water cycle between the heat exchange unit and the outside recovers; if the water qualitydoes not reach the standard, the above steps are conducted continuously; and the water cycle between the heat exchange unit and the outside is cut off so that the inner cycle can be formed between thesecondary side heat exchanger and the energy mixing device, medicament adding and online flushing are conducted on the energy mixing device and the secondary side heat exchanger, the flushing efficiency is improved, the equipment service life caused by frequent demounting is prevented from being shortened, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of heat exchange units, in particular to a cleaning method for a hybrid heat exchange unit with a water quality detection function. Background technique [0002] The traditional plate heat exchange unit is mainly composed of multiple plate heat exchangers, circulation pumps, water supply pumps, valves and filters. [0003] In the prior art, when cleaning the secondary side heat exchanger, the heat exchanger needs to be dismantled, and the heat exchange fins are taken out one by one for cleaning. Online chemical dosing and cleaning cannot be realized. Frequent disassembly leads to a reduction in the life of the heat exchange unit, and the work is cumbersome. The cost is high and the effect is poor. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a cleaning method for a hybrid heat exchanger unit with a water quality detection function. By cu...
