Particularly, the filter element of the utility model can be selected from the filter elements of the filter screens and the membrane media with different precisions in the prior art for filtration. The specific filtering process comprises the following steps: after cyclone separation, the slag in the wastewater stock solution is on the outer side and the oil is in the center. The slag and oil content in the cyclone intermediate layer are greatly reduced, and then the clean liquid flows out of the water outlet of the cyclone filter barrel for recycling through the precise filtration of the straight tube filter element wall; meanwhile, the swirling liquid has a washing and cleaning effect on slag and oil gathered on the inner wall of the straight tube filter element, and the effect of automatically cleaning the filter element is achieved.

In addition, when the filter element is used for a period of time and the filtering efficiency is greatly reduced due to pollution and blockage, the filter element can be reversely pressurized through the water outlet flushing port of the rotational flow filtering barrel, under the action of pressure, clean liquid on the outer side of the straight pipe filter element can reversely flush the filter element, and pollutants and blockages on the filter element can be reversely flushed back into the waste water stock solution, so that the effect of backwashing the filter element is achieved.
