Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a high-pressure filter. Background Art

[0002] In the thermal system of thermal power generation, the high-pressure filter is an important component of the thermal system. All sample water must be filtered by the high-pressure filter before entering the instrument electrode for measurement. Therefore, the technical level of the high-pressure filter and the quality of the product directly affect the accuracy of the instrument measurement of the thermal power generating unit, and thus affect the safety, reliability and economic operation of the unit.

[0003] At present, split high-pressure filters are mostly installed in sample water pipelines. In split high-pressure filters, sample water enters the filter cylinder through the inlet of the high-pressure filter, and then enters the inner cavity of the filter element after being filtered by the split filter element. Impurities larger than the gap of the filter element are retained, and pure sample water passes through the gap to reach the inside of the filter element, and finally is sent out from the outlet of the high-pressure filter. In the actual production process, although the split high-pressure filter can achieve sample water filtration, the split high-pressure filter has low filtration accuracy, is not easy to disassemble and assemble, and has high assembly difficulty, which increases the maintenance cost of the power plant. For this reason, we propose a high-pressure filter to solve the above problems. Utility Model Content
