Description

Technical Field

[0001] The present invention belongs to the technical field of heat exchangers, and in particular relates to a heat exchanger water treatment device and a treatment method thereof. Background Art

[0002] After long-term use, the pipes and equipment of the heat exchanger are prone to rust and structure, which will deteriorate the water quality. This will not only affect the use of hot water, but may also cause the pipes to be blocked during use. Therefore, a filter plate is needed to filter the water.

[0003] Traditional filter plates are usually flat plates, and filtered water will be filtered out from the same position on the filter plate, which will cause the filter plate to be blocked. When unclogging the filter plate, the heat exchanger usually needs to be shut down, which makes the heat exchanger work inefficiently. In order to solve the above problems, a heat exchanger water quality treatment device is now provided.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a heat exchanger water quality treatment device and a treatment method thereof. By setting a raised filter net, the filtered water can flow from the filter net to the collection box, avoiding the filtered water from being filtered out from the same position on the filter net, thereby reducing the probability of clogging of the filter net component. By setting at least two filter components, other filter components can be activated when unblocking the filter component, avoiding the heat exchanger from shutting down during the unblocking process, thereby ensuring the working efficiency of the heat exchanger.

[0006] To achieve the above-mentioned purpose, the present invention proposes a heat exchanger water quality treatment device, the treatment device includes a filter assembly, the filter assembly includes a filter box, a first connecting pipe and a second connecting pipe are both connected to the inside of the filter box, an opening is provided on one side of the filter box, a filter assembly is installed in the filter box, the filter assembly can filter the box from near the opening, and a control assembly for controlling the movement of the filter assembly is fixed on the filter box.

[0007] The filter assembly comprises a mounting block mounted in the opening, a collecting box is fixed on the mounting block, a convex filter is fixed above the collecting box, and a water filtering hole is arranged inside the collecting box.

[0008] Furthermore, a sealing plate is fixed to one end of the mounting block located outside, and a rubber layer is provided on one side of the sealing plate close to the filter box.

[0012] Furthermore, the filter assembly also includes a waste box, which is located directly below the support plate.

[0013] Furthermore, a hook is fixed on one side of the filter box, and a hook adapted to the hook is fixed on the waste box.

[0014] A heat exchanger water quality treatment method is applied to the above-mentioned treatment device, and the treatment method is as follows:

[0015] Open the corresponding first switch valve and the second switch valve, so that the hot water output by the heat exchanger flows through the corresponding filter box. During the flow, impurities in the hot water are filtered through the filter assembly. By observing the two corresponding first flow meters and the second flow meters, if the flow of the first flow meter is greater than the preset value of the second flow meter, the corresponding filter assembly is unblocked and replaced with another filter assembly.
