Description

Technical Field

[0001] The invention relates to the technical field of filters, and in particular to a petrochemical pipeline filter. Background Art

[0002] Pipeline filter is a small device to remove solids from liquids. It is mainly used in the transportation of weak acid media such as chemical petroleum. Its working principle is that when the fluid enters the filter cartridge through the main pipe, the solid impurity particles are blocked in the filter cartridge, and the clean fluid is discharged through the filter cartridge and the filter outlet.

[0003] Existing pipeline filters are usually installed at wellheads, pumping stations, oil production stations or upstream of pipelines when used for oil transportation filtration. The filters can filter out impurities, broken rocks and gravel to ensure the quality of oil and the safety of equipment. However, the disadvantage of pipeline filters is that they are easy to clog and difficult to handle. The filter plates must be replaced, and replacing the filter plates will result in the inability to continuously transport the fluid.
