2, the material after preheating in waste grease screening installation 1 is delivered in measuring tank 3 and is counted by delivery pump 1Amount, sampling, metering adopts the module of weighing to carry out Weighing, and the sample sealed storage of sampling is delivered to chemical examination center and is detected,The object of metering, sampling is the quality and quantity of checking oil product;
3, measuring tank 3 is fallen into a trap and is measured material after sample and be delivered to wet solution in tank 5 by delivery pump 2 200 and heat-treat, the wet tank of separating5 is low-pressure pressure container, and charging aperture arranges seal gate valve, and to ensure air-tightness, material is damp and hot at the wet high temperature that carries out in separating tank 5Reaction, thermal source is high temperature saturated vapor, this steam directly passes into wet solution in tank 5 tank bodies by injector, and material is added fastHeat, through the damp and hot reaction under certain hour, uniform temperature and pressure, combustion improves, grease fully melt separate out,Reduced viscosity, has improved efficiency and the effect of follow-up separation operation;
4, after material has reacted in wet solution tank 5, the wet blow-off valve of separating tank 5 is opened, and material enters in sorting press apparatus 7,In sorting press apparatus 7, by equipment for separating liquid from solid, liquid phase mixture is fully separated with solid particulate matter, the liquid after separationPhase materials enters liquid phase storage tank, and the non-organic foreign material of bulky grain are discharged by foreign material discharge gate, to material carry out artificial re-scheduling slag andImpurity outward transport is processed;
5, by after sorting press apparatus 7 Separation of Solid and Liquid, be stored in the main component of the liquid phase material of liquid phase storage tank be grease, water andOrganic particulate matter, these liquid phase materials are sent into the three-phase separate that carries out oil, water, slag in three-phase separator 9 by delivery pump 4 400From, separation principle is the different specific weight characteristic according to different material component, realizes light, heavy material in the centrifuge of High Rotation SpeedSeparation, obtain highly purified oil and fat product;
6, in three-phase separator 9, through centrifugation, the grease in material is separated from solution, isolated grease entersEnter in grease surge tank 10 and keep in, then be delivered in oil storage tank 12 and store through oil transfer pump 1, the grease after storage is by defeatedOil pump 2 600 is delivered to transfer container, and isolated water material is collected and entered regulating reservoir by pipeline, after homogeneous regulates, sendEnter sewage disposal system and carry out advanced treating, in the isolated residue slag charge of three-phase separator 9 owing to containing sandstone, glass, potteryThe heavy particle such as porcelain, so after centralized collection storage, slag charge is sent to landfill yard by transfer car(buggy) and carries out harmless treatment.
To sum up, the full-automatic pretreatment system of meal of the present invention kitchen waste grease, method at least have following beneficial effect:
1, innoxious degree is high:
The meal kitchen innoxious degree of process for carrying out pretreatment on waste oil of taking as the leading factor with the warm and humid solution of height is high, and meal kitchen waste grease is at the wet tank 5 of separatingMiddle process is no less than the thermophilic digestion processing of 30 minutes, all deactivations of bacterium and various virus;
2, recycling rate is high:
Meal kitchen waste grease is after HTHP boiling, and animal and plant fat all deviates to enter grease phase, can realize higher oilThe fat rate of recovery, only has a small amount of different miscellaneous material to need landfill burning disposal after treatment;
3, system equipment seal is strong, and environment is easily controlled:
Except sorting press apparatus 7 in discharge process in open state, all the other all devices are equipped with sealing device, realizeClosure production operation, various kinds of equipment and storage tank all move under sealing state, deodoration system can to foul gas realize collectProcess, effectively control secondary pollution;
4, automaticity is high, simple to operate.
The technical field scope that treatment system of the present invention and method relate to is larger, has contained mechanical kinetics, industrial automation controlVarious, multi-disciplinary technique and the technology such as system, microbiology, biochemistry, thermophysics, Environmental Engineering, in protectionThe aspects such as environment, extended resources circulation have realized technological innovation. Complete meal kitchen waste grease pre-processing device provided by the invention,Comprise waste grease screening installation 1, measuring tank 3, wet tank 5, sorting press apparatus 7, three-phase separator 9, the grease buffering of separatingTank 10, oil storage tank 12 etc., adopt the system of the said equipment composition to carry out pretreatment to meal kitchen waste grease, technique consuming time short,Equipment is few, reliability is high.
In sum, system and method for the present invention by high warm and humid solution pretreating process to each main group in meal kitchen waste greaseSeparate pretreatment, improved efficiency and the effect of meal kitchen waste grease harmless treatment, improved meal kitchen abandoned oil simultaneouslyThe economic benefit of fat resource product, has reduced meal kitchen waste grease processing cost.
Above-described embodiment is described the preferred embodiment of the present invention, not scope of the present invention is carried outLimit, design under the prerequisite of spirit not departing from the present invention, those of ordinary skill in the art make technical scheme of the present inventionVarious distortion and improvement, all should fall in the definite protection domain of the claims in the present invention book.
