Commonly used grease traps have advection and mixed flow of two types. Particles flow from one end of the pond water pond to the lower level of the flow rate (2 ~ 5mm / s) flow through the pool buried grease-flow process, the particle density less than water, the oil rises to the surface, a density greater than water impurities sink to the bottom, the outflow of water from the other side of the pond. Set in the grease trap effluent collection pipe end. Set pipe diameter tubing for general use is made of 200 to 300 along the length of the arc on the side wall opening width of 60? Or 90? Notch. Collecting pipe can be rotated around the axis. The steering set slotted below the horizontal direction of the tubing to collect the oil slick, and export outside of the pool when the discharge of oil slicks. In order to exclude the timely discharge of oil and sediment stainless steel grease traps, grease traps should be set in a large scraper scraper. Moving scraper scraper scraper speed should generally be similar to the flow velocity in the pool in order to reduce the impact on water flow. Collected in mud sludge bucket to drain away from the mud in the bottom of the tube by means of hydrostatic pressure. Grease trap sedimentation tank bottom structure and the same. Scum grease traps, oil-based, but also contains water and some solid impurities. Oil industrial wastewater, water content and sometimes up to 50% Xi'an stainless steel grease traps, and other impurities generally about 1% to 20%. Relying solely on the density difference between droplets and water and for generating floating oil and water separation, the oil removal efficiency is generally about 70% ~ 80%, the grease trap effluent still contains a certain amount of emulsified oil and suspended solids deposited on the oil, is generally less difficult reduced emissions standards. Flotation separation of oil and water is better, the oil content of the effluent is generally less than 20mg / L. For small grease traps rail transport, chemical and other industries, which rely on oil skimming device is the density difference between water and oil formation level difference and achieve the purpose of automatic skimmers. Grease trap design and advection advection sedimentation tanks are similar, according to the design surface load, the general 1.2m3/m2 & *** dot; h; according to the design of the residence time, the general 2h.
