Abstract
The present invention provides a method of extraction and purification of waste oil, relating to recycling of waste resource, waste oil discharged by the present catering trade contains more oil, bringing trench blockage and waste of resource, the resolving steps of the invention include: input the waste liquid in the recycling separation groove, filtering oil in a low temperature and a high temperature after separating oil with water, then vaporizing water; further sterilizing and packing, the product is obtained. The invention not only achieves the recycling of oil resource, protecting environmental sanitation, but also has advantages of simple equipment, convenient operation, easy to extension.
Description
Technical field:
The present invention relates to the resource recycling field, especially the utilization of waste resource.
Background technology:
Catering trade has a large amount of waste liquids to discharge, and contains many greases in waste liquid, wherein has plenty of fried useless oil, has plenty of the oil in the vegetable soup, the oil of discharging when having plenty of washing.At present, these waste oil enter trench with waste water drains, but because the zero pour of oils is higher, and lard particularly very easily solidifies in trench, forms trench and stops up.So sewer oil has caused two large problems: the one, environmental issue causes the waste water crossing current after trench stops up, and summer is smelly easily, has a strong impact on environment; The 2nd, the waste of resource, a large amount of waste oil can utilize again, as the sanitas of lubricating oil, the building materials of machinery, separant etc.But collection recovery and the purifying to sewer oil also is not much accounted of at present, do not have the technology of a cover standard yet.
Summary of the invention:
Purpose of the present invention is for providing a kind of technology simple, and is easy to operate, can be the trench oil recovery purification process of everybody acceptance.
Realize that foregoing invention purpose technical scheme is as follows:
Trench oil recovery purification process has the following step:
(1) sewer oil enters the recovery separator tank, carries out oily water separation, and with upper strata oil reservoir input filter at low temperature groove, lower aqueous layer is discharged;
(2) carry out coarse filtration in the filter at low temperature groove, temperature is 30-50 ℃, and coarse filtration oil is imported the high temperature filtration groove again;
(3) carry out the essence filter in the high temperature filtration groove, temperature is 50-95 ℃, and smart oil strain is imported evaporator tank again;
(4) in evaporator tank water evaporates is fallen, anhydrous oil enters sterilizer;
(5) in sterilizer, carry out disinfection;
(6) packing.
Described recovery separator tank, its structure has liquidometer at the cell wall middle part, and the oil export valve is housed for have the sewer oil inlet on cell wall top, and the wastewater outlet valve of band guard is housed in the cell body bottom.Have well heater in described filter at low temperature groove and the high temperature filtration groove, in the exit filtering net is housed, the filtering net specification in filter at low temperature groove exit is the 20-50 order, and the filtering net specification in high temperature filtration groove exit is the 50-120 order.
When oily water separation was operated, oil water surface was higher than the oil export valve in the separator tank as reclaiming, and then opens the wastewater outlet valve of bottom earlier, and some waste water of draining treat that oil water surface is lower than the oil export valve slightly, open the oil export valve again, and oil is imported in the filter at low temperature groove.
The Waste Water Centralized that discharge in the Duo Jia restaurant can be reclaimed separation together during the invention process, to realize mass-producing, cost degradation.Higher or acidity, basicity are higher as the waste water salinity of discharging, and can add an amount of water in reclaiming separator tank, stir with oil, form the emulsification shape, treat the separating of oil step process that descend again of static back water, to guarantee oily degree of cleaning.
The present invention also has the life-span of improving water shoot except that recycling that can reach oily resource and protection environmental health, reduce the expense of cleaning water drain, and equipment is simple, the easy to operate and beneficial effect that is easy to promote.
Description of drawings
Fig. 1 is the process flow sheet (slot type) of trench oil recovery purification process of the present invention
Fig. 2 is for being the structural representation of well formula oily-water seperating equipment.(well formula)
Embodiment
Fig. 1 has shown a kind of embodiment of the present invention, has sewer oil inlet 2 on the top of reclaiming separator tank 1, has liquidometer 3 at the cell wall middle part, oil export valve 4 is equipped with at height place at liquidometer, in the cell body bottom wastewater outlet valve 5 is housed, agitator 6 and waste water filtering net 7, filter at low temperature net 8, high temperature filtration net 9.The well heater that is contained in filter at low temperature groove and the high temperature filtration groove is electric heater or steam heater, at bottom land the waste residue vent pipe is housed, and sterilizer can adopt high-pressure sterilizer or ultraviolet disinfector.The waste residue of discharging in this technology can be used as the clay fertilizer use through sending out alcohol.
Fig. 2 has shown the structure of well formula oily-water seperating equipment, and it utilizes missile silo to build, and has sewer oil inlet 10, wastewater outlet bend pipe 11, guard 12, the oil after the separation is drawn out with spoon, carries out filter at low temperature, high temperature filtration, evaporation sterilization again and packs each step.
Claims (3)
