Description
Technical Field
The invention relates to the technical field of micro-channel heat exchangers, in particular to a filter cloth type filtering device used in a pressure-bearing container.
Background
Printed circuit plate heat exchangers (PCHE) belong to the category of microchannel plate heat exchangers. The PCHE has the advantages of compact structure, high temperature resistance, heat transfer resistance, safety, reliability and the like, and is widely applied in the fields of refrigeration and air conditioning, petroleum and natural gas, nuclear industry, chemical industry, electric power industry and the like. However, such heat exchangers also have some drawbacks in use, the main problems being that the PCHE heat exchanger channels are too small to be easily clogged and difficult to clean once clogged. Therefore, a filter is generally required to be installed before the inlet of the heat exchanger.
Generally, the channel of the PCHE heat exchanger needs to be very fine to achieve the effect of the micro-channel heat exchanger, and the aperture of the filter screen needs to be smaller than the diameter of the channel of the PCHE heat exchanger to meet the requirement of the filtering precision. At present, the common diameter of the PCHE heat exchanger is about 1mm, so the aperture of a filter screen matched with the PCHE heat exchanger can meet the requirement of filtering precision only when the aperture is about 100 to 200 meshes.
The water pipeline filters commonly used at present, such as Y-type filters, basket filters, etc., either cannot meet the requirements of filtering precision or have too much resistance to prevent the normal flow of fluid. On the other hand, since the PCHE heat exchanger is generally applied in a high pressure situation, even if the PCHE heat exchanger is used for heat exchange of cooling water, the pressure of the cooling water is 0.6MPa or higher, and therefore, many common high-precision and low-resistance filters, such as a filter of a conventional biomass water treatment device, a water filter of a sewage treatment plant, and the like, which operate under normal pressure cannot meet the use requirement under the working condition.
