Desulfurizing dust-collector import is connected with air-introduced machine outlet;Plastic filler, configuration circulation spray are loaded inside desulfurizing dust-collector Leaching system.
The application of described device, includes the following steps:
1) solid-liquid separating machine:Greasy filth in greasy filth pond pours into solid-liquid separating machine through manually loading feeder hopper after lifting Rotation pick up cage, pick up cage wall be provided with it is countlessHole, under the action of motor, picks up cage rotation, picks up cage inner wall sawtooth tear plastics Debris and to another lateral movement, while the current that high pressure nozzle sprays rinse, sewage is flowed down through micropore, the larger gravel warp of density Discharge port flows out, and plastics etc. pass through artificial screening, is flowed out through another discharge port, and tiny silt is settled in bottom;
Moulded coal is housed in combustion chamber, by Combustion of Mould Coal, grease is heated, beneficial to water-oil separating, the tail gas of burning passes through Coil pipe is discharged, while heats sewage, realizes Waste Heat Recovery;The gravel that hopper comes out, surface carries greasy filth, into positioned at combustion chamber The feed inlet of the scrapper conveyor of bottom, under the action of scrapper conveyor, gravel enters combustion chamber, is scraped together with the moulded coal of after-flame, During walking, under the high temperature action in burner hearth, the greasy filth pyrolytic burning on gravel surface, reaches purification purpose;
Separation of solid and liquid motor spindle is in cone bucket shape, and tiny silt deposits herein, by the scrapper conveyor of bottom, by tiny silt Scrape, add fuel mixer, greasy filth aqueous mixtures gravity is discharged into oil water separator and carries out water-oil separating;
2) plastic rinse crusher:The plastics of step 1) are added from the entrance for rinsing crusher, in the blade of crusher Effect is lower broken, meanwhile, the current sprayed by high pressure nozzle rinse, and achieve the purpose that further to clean, and clean plastics return Receive and utilize, oily wastewater flows into oil water separator certainly;
3) oil water separator:The oily wastewater of step 1) and step 2) flows into oil water separator, under the action of air blower, The perforated pipe release micro-bubble of oil water separator bottom, accelerates water-oil separating, and the oil on upper strata flows into oil sump recycling, sewage stream certainly Enter cesspool, part water is recycled to be used in step 1) and step 2);
4) smoke desulfurization dust remover:The flue gas of step 1) is introduced through air-introduced machine from smoke desulfurization dust remover import, flue gas Move from bottom to top, meanwhile, adverse current hydro-peening lye, under the action of plastic filler, lye cuts into droplet and frosting Very thin liquid layer is formed, is come into full contact with flue gas, achievees the purpose that purifying smoke, purifying smoke is discharged from the gas outlet on top, Lye recycles.
5) sludge dewatering:Step 1) greasy filth flows into settled sludge and arranges pond, and inside sets mixer, in the effect of mixer Under, stirring arranges uniformly, high pressing dehydrator is pumped into through low pressure slush pump, when pressure rise is to 0.4MPa, using high pressure oil pressure Pump continues feeding, until pressure is raised to 20MPa, discharging after pressurize for a period of time, moisture content of the cake at this time is less than 50%.
6) briquette molding:The mud cake that step 5) is unloaded manually adds pulverizer, is ground into 0.5-1cm particle diameters, manually again Fuel mixer is added, while adds coal dust and the fine deposit of step 1) discharge, after mixing, moisture content reaches 45~55%, defeated Send to briquet former, compression forming reuse combustion chamber.
Compared with prior art, the present invention have the following advantages that:
(1) it is directed to greasy filth, gravel and plastics contained in greasy filth etc. to be separated, realizes that recycling recycles, gravel is used In paving the way, plastics recycling, avoids the secondary pollution caused by landfill.
(2) the fine deposit that solid-liquid separating machine scrapes is mixed with the clod after crushing, coal dust, is molded instead of loess, is realized at the same time The purification of fine deposit, avoids secondary pollution caused by silt.
(3) solid-liquid separating machine floor space is small, and the residence time is short, and the degree of automation is high, and failure rate is low, and sludge contains after processing Oil cut rate≤2%.
(4) high pressing dehydrator equipment operation letter, it is single stable, avoid filter cloth breakage.High pressing dehydrator floor space Small, the residence time is short, and the degree of automation is high, and failure rate is low, and operating pressure is up to 20~25MPa, and moisture percentage in sewage sludge after processing≤ 50%;
(5) the moulded coal produced is back to combustion chamber, solves the problems, such as moulded coal market, reduces oil-sludge treatment cost.
(6) the set system can be widely used for petroleum chemical industry oil-sludge treatment, and small with floor space, operation is simple and reliable, One-time investment is low, and operating cost is low, realizes resource recycling.

    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.
