    The oily wastewater of step (1) and step (2) flows into oil water separator, under the action of air blower, oil water separator bottom Perforated pipe release micro-bubble, accelerate water-oil separating, upper strata oil from flow into oil sump recycling, sewage flow into cesspool, part Water is recycled to be used in step (1) and step (2) introduces, and flue gas moves from bottom to top, meanwhile, adverse current hydro-peening lye, is filled out in plastics Under the action of material, lye cuts into droplet and frosting forms very thin liquid layer, is come into full contact with flue gas, reaches smoke-purifying The purpose of gas, purifying smoke are discharged from the gas outlet on top, and lye recycles；
    (5) sludge dewatering
    Step (1) greasy filth flows into settled sludge and arranges pond, and inside sets mixer, and under the action of mixer, stirring arranges uniformly, High pressing dehydrator is pumped into through low pressure slush pump, when pressure rise is to 0.4MPa, feeding is continued using high pressure oil pressure pump, until pressure Power is raised to 20MPa, discharging after pressurize for a period of time, and moisture content of the cake at this time is less than 50%；
    (6) briquette molding
    The mud cake that step (5) unloads manually is added into pulverizer, 0.5-1cm particle diameters is ground into, manually adds fuel mixer, Coal dust and the fine deposit of step 1) discharge are added at the same time, after mixing, moisture content reaches 45~55%, is delivered to briquet former, Compression forming reuse combustion chamber.
