Abstract

The utility model relates to a special efficient device for separating oil from water, and is composed of an outer housing, a centrifugal barrel, a wastewater barrel, a stirrer, a motor, a timer and a deoiling bag, wherein, the latter is formed by processing materials with extremely strong lipophilic property, such as polypropylene fibers, polyurethane foam, etc. into small pieces which are sealed and packed by gauze into bags. The utility model absorbs oil from oily wastewater and discharges the absorbed oil through centrifugal separation after clear water is discharged so that the purpose of oil-water separation can be achieved. The utility model can be used for the treatment of environmental protection, and the deoiling rate reaches more than 95 per cent. The utility model has the advantages of simple structure, easy manufacture, convenient operation and low price.

Description

Special efficient device for separating oil from water

The utility model belongs to a kind of wastewater treatment equipment.

Oily(waste)water has become one of environmentally hazardous principal pollutant.It is mainly from industries such as oil, petrochemical complex, iron and steel, coking, gas generating station, mechanical workout and food.Its feature is that the kind of waste oil exists complex shape more, and mineral oil, vegetables oil, animal oil are arranged, can divide into again by form floating oil, dispersed oil, emulsification wet goods.At present, being used to handle the oily(waste)water device has SCF, CyF and ySF series water-and-oil separator, and they adopt gravity separation and the isolating unitized construction of coarse (referring to 408 pages of efforts at environmental protection person's application manuals, metallurgical industry press, 1984) mostly.This class water-and-oil separator is not suitable for the waste water that contains oil in water emulsion, animal oil, because wherein oil is in high dispersion state, above-mentioned water-and-oil separator is powerless to this type of oily(waste)water, and this class apparatus structure complexity, and heaviness costs an arm and a leg, and is also not easy to operate.

In order to solve oil in water emulsion water sepn problem, before using water-and-oil separator, often need to use the chemical process breakdown of emulsion, this way is weak effect not only, and the chemical substance that adds has caused secondary pollution again.

The purpose of this utility model is to provide a kind of special efficacy water-and-oil separator, and it is applicable to the oily water separation of various oily(waste)waters, and effective equally to being difficult to isolating oil in water emulsion.The efficient of its oily water separation is very high, and can not cause secondary pollution.

In the utility model, utilize the extremely strong material of a kind of lipophilicity, the processing frustillatum, be packaged into bag with gauze, constitute the de-oiling bag, put it in the oily(waste)water, use mechanical stirring, lipophilicity material oil abundant and in the waste water in this de-oiling bag is contacted, and, so just reached purpose oily, water sepn its absorption, emit the waste water that is substantially free of oil subsequently again, the last oil of telling lipophilicity material absorption in the de-oiling bag again with centrifugation method.

Accompanying drawing is a structural representation of the present utility model.Among the figure, the shell of 1 water-and-oil separator, 2 centrifugal barrels, 3 wastewater barrels, 4 agitators, 5 oil outlets, 6 motors, 7 regulate pin, 8 water outlets, 9 supply leads, 10 stirrer shafts, 11 timers, 12 waste water inlets, 13 lids, 14 upper entrances, 15 de-oiling bags.The shell 1 of water-and-oil separator is box-shaped, covers 13 and upper entrance 14 above; Partly there is centrifugal barrel 2 at center in shell 1 inside, and the latter is cylindrical, is covered with aperture on its side, and de-oiling bag 15 just is placed in the centrifugal barrel 2, and wastewater barrel 3 is outer concentric drums of centrifugal barrel 2; Agitator 4 partly is equipped with at the center of centrifugal barrel 2, and the latter is connected with motor 6; Oil outlet 5 and water outlet 8 are arranged at the bottom of shell 1, and they all communicate with wastewater barrel 3; Shell 1 bottom has 4 to regulate pin 7, and there is supply lead 9 at the rear portion, and timer 11 is arranged at the top of shell 1, and other has a waste water inlet 12.Lipophilicity material in the above-mentioned de-oiling bag 15 can be that polypropylene fibre also can be polyurethane foam, ester type polyurethane foams, foam styrene goods and organic property powder body.

When using the utility model, can oily(waste)water be injected centrifugal barrel 2 and wastewater barrel 3 by waste water inlet 12, because the lipophilic material proportion in the de-oiling bag 15 is less, so these de-oiling bags 15 just are suspended on the waste water surface, start motor 6, stir waste water, then de-oiling bag 15 just sinks, fully contact with the oil in the waste water, and with its absorption.After stirring certain hour, just reached the purpose of oily water separation.Churning time is relevant with the existence of oil in the waste water, and the particle diameter of elaioleucite is more little, and the time that needs is long more, is generally about 5 minutes.Stirring finishes, and divides fuel-displaced clear water afterwards to be discharged by water outlet 8 by gravity.Can make oil break away from lipophilic material by the centrifugal way after de-oiling bag 15 oil are saturated, and discharge from oil outlet 5.Oleaginousness is very little in the clear water, and the de-oiling rate reaches more than 95%.The oil and the clear water of discharging all can utilize, and the lipophilicity material can use repeatedly.

The utility model can be made vertical, can also make horizontally, and its amount of capacity is by the decision of the amount of waste water.

The utility model is simple in structure, makes easily, is convenient to operation, low price, oil removal rate height.

Claims
