Abstract

The invention discloses a cleaning method of an energy mixing heat exchange unit with a pipeline online flushing 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 comprises the following steps that a pipeline communicating between the secondary side heat exchanger and the energy mixing device is closed to prevent water in the pipeline from flowing to the secondary side heat exchanger; the pipeline and the energy mixing device are cleaned; impurities contained in the water in the pipeline are filtered away, and the pressure difference before and after filtering is detected; when the pressure difference is greater than a set value, the filteredimpurities are removed, clean water is supplemented into the pipeline, and the steps 2-4 are repeated; and when the pressure difference is smaller than the set value, the pipeline communicating between the secondary side heat exchanger and the energy mixing device is opened, and cleaning of the two-network pipeline is achieved by setting up the energy mixing device.

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 an online flushing function for pipelines. 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 flushing the secondary side pipe network, an external large-lift water pump is required and some components are disassembled and separated. Frequent disassembly leads to shortened equipment life, cumbersome work, high cost and poor effect. Contents of the invention

[0004] In order to solve the above-mentioned technical problems, the present invention provides a cleaning method for a hybrid heat exchanger unit with an online pipeline flushing function. By closing the pipeline between the mixer and the secondary side heat exchanger, the mixer and the seconda...
