Description

a grease trap

technical field

The utility model relates to the technical field of oil-water separation, in particular to a grease trap, which is mainly used in various gas stations.

Background technique

The oil separator is a treatment structure that uses the difference in specific gravity between oil and water to separate and remove suspended oil with larger particles in sewage. Petroleum industry and petrochemical industry discharge waste water containing a large amount of oil in the production process; coal coking and gasification industry discharge waste water containing high concentration of tar; wool spinning industry and meat industry discharge waste water containing more oil. If these oily waste water is discharged into the water, it will cause pollution, and the irrigation of farmland will block the soil pores, which will harm the growth of crops. If the oil in the waste water is recycled, it can not only avoid environmental pollution, but also obtain considerable economic benefits.

The structure of the grease trap mostly adopts the advection type. The oily wastewater enters the rectangular grease trap through the water distribution tank and flows slowly along the horizontal direction. During the flow, the oil floats on the water surface and is pushed by the oil collecting pipe or the oil scraper installed on the pool surface. to the oil collector and flow into the dehydration tank. The heavy oil and other impurities settled in the grease trap accumulate in the sludge bucket at the bottom of the tank, and enter the sludge pipe through the sludge discharge pipe, so as to achieve the effect of purification and reduce the outflow of harmful substances. At present, the existing grease trap has poor oil separation stability and oil-water separation effect, which further increases the difficulty of post-processing, and the processing cost is relatively high.
