Working principle editor 1: oily sewage is pumped to the oil-water separator by the sewage pump, and after passing through the diffusion nozzle, large oil droplets float on the top of the left oil collection chamber.

2. Sewage containing small oil droplets enters the corrugated plate coalescer at the lower part, where the oil droplets are polymerized into larger oil droplets and sent to the right oil collection chamber.

3. The sewage containing smaller oil droplets passes through a fine filter to remove impurities in the water, and then enters a fiber polymerizer in turn, so that the small oil droplets are polymerized into larger oil droplets and separated from water.

4. The separated clean water is discharged through the discharge port, the dirty oil in the left and right oil collection chambers is automatically discharged through the electromagnetic valve, and the dirty oil separated in the fiber polymerization kettle is discharged through the manual valve.

The invention is mainly suitable for the environment with serious pollution caused by domestic oily sewage discharge. The oil-water separator is an imported "grease trap", which is installed at the outlet of the sewer to prevent oil and garbage from being discharged into the sewer. Mainly made of FRP, stainless steel and other materials. Due to the advanced design (the product and its design have obtained patents at home and abroad), the oil blocking rate can reach more than 90%.
