3. Efficient pollution discharge: the dirt separator has a large barrel body, so that water can be fully expanded after entering the barrel body, the flow rate of system water is reduced, and impurities in the system are precipitated at the bottom of the dirt separator so as to be removed in time during dirt discharge; the supporting plate is arranged below the filter cylinder, holes are drilled in the supporting plate, and the drilling precision and the filter screen precision of the filter cylinder are the same, so that impurities in the filter cylinder can be discharged to the bottom of the dirt separator, and deposition and blockage of impurities are avoided.

4. Low resistance and low pressure drop: the system in the cylinder has low flow velocity, and simultaneously, the filter screen has large flow volume, corresponding resistance is low, pressure drop is small, the hydraulic balance of the whole system is not influenced, and the system is favorable for running.
