Abstract

The utility model designs a cyclone settling separation device which is provided with a cyclone separator or a cyclone separator set in a casing of a settling tank or outside the casing of the settling tank. The process of the settling separation is strengthened under the action of the rotary flow field of the cyclone separator. The utility model which can proceed with the separation for an unmixing liquid-liquid system is suitable for the separation of a liquid-solid system and is also suitable for three-phase separation for the solid, the liquid and the liquid. The volume of the settling tank is remarkably decreased, the operation is simple and reliable, and the structure is compact.

Description

The eddy flow settling separation device

Technical field:

The utility model belongs to the technical field of the separation equipment of liquid-liquid or liquid-solid mixture, especially is fit to a kind of eddy flow settling separation device that oil-polluted water is separated.

Background technology:

In the production process of petrochemicals, by land in the oil recovery process of oil field and marine oil field, often to discharge the sewage of a large amount of oil-containings, these sewage cause serious pollution to environment, must handle.

At present, following two kinds of methods are usually adopted in the processing of these sewage: 1. sedimentation, 2. filtration method.

Said sedimentation is that sewage is placed big jar earlier, after staying for some time, the light components that swims in the upper strata is cast aside away, to reach the purpose of separation.The shortcoming of this method is that equipment volume is huge, and floor space is big, moves discontinuously, and equipment investment is higher;

Said filtration rule adopts filtrate to receive oil, and it need regularly clean, inconvenient operation.

In recent years, developed the technology that hydrocyclone is handled oil-polluted water again, but in the application process of reality, found also to exist the not high defective of water-oil separating efficient, and also must be further improved.

Summary of the invention:

The purpose of this utility model is to design a kind of novel settling separation device, strengthens the sedimentation separation effect with cyclone separator, to overcome the above-mentioned defective of prior art.

Technical scheme provided by the utility model is, design a kind of novel eddy flow settling separation device, it is characterized in that described eddy flow settling separation device comprises cyclone separator 2 and settling tank 5, the underflow discharge zone 12 of cyclone separator 2 and overflow pipe 7 communicate with settling tank 5 chambers respectively.

In the described eddy flow settling separation device, cyclone separator can be arranged in the settling tank chamber, also can be arranged on outside the settling tank, and eddy flow sedimentation separation jar can be vertical, also can be horizontal.According to the difference of treatment media and purpose, cyclone separator is arranged on the diverse location of settling tank; To being used for the de-oiling purpose, it is 7/10～4/5 place of settling tank total height that cyclone separator should be arranged on apart from the settling tank bottom level; To being used for the sand setting purpose, it is 1/5～3/10 place of settling tank total height that cyclone separator should be arranged on apart from the settling tank bottom level; To being used for de-oiling sand setting purpose, it is 1/5～1/4 place of settling tank total height that cyclone separator should be arranged on apart from the settling tank bottom level; Said cyclone separator should be the oil-polluted water import of cyclone separator apart from the settling tank bottom level apart from the settling tank bottom level.

The employed cyclone separator of the utility model can be de-oiling type liquid-liquid rotational flow separation device, dehydration-type liquid-liquid rotational flow separation device and solid-liquid rotational flow separation device, as Chinese patent 95228292.5,96210084.6 and 00217613.0 cyclone separator of announcing etc.

The utility model is by being provided with a cyclone separator or cyclone separator group in the settling tank housing or outside the housing, under the effect of cyclone separator rotational flow field, strengthened the sedimentation separation process, both can immiscible liquid-liquid system be separated, also be applicable to liquid-solid system separation, also be applicable to solid-liquid-liquid three phase separation.Can significantly reduce the settling tank volume, operation is simple and reliable, compact conformation.

Below in conjunction with the drawings and specific embodiments the utility model is further described:

Among Fig. 1: 2-cyclone separator, 3-oil drain out, 4-support, 5-settling tank, 6-discharge outlet, the import of 8-oil-polluted water;

Among Fig. 2,7-overflow pipe, the import of 8-oil-polluted water, 9-cylinder chamber section, 10-tapering chamber section, 11-tailpipe section, 12-underflow discharge zone;

Among Fig. 3, the import of 8-oil-polluted water;

Among Fig. 4,2-cyclone separator, 3-oil drain out, 5-settling tank, 6-discharge outlet, the import of 8-oil-polluted water;

Among Fig. 5 ,-cyclone separator, 3-oil drain out, 4-support, 5-settling tank, 6-discharge outlet, the import of 8-oil-polluted water;

By Fig. 1, Fig. 2 as seen, said eddy flow settling separation device comprises cyclone separator 2 and a settling tank housing 5, and cyclone separator 2 is fixed on the settling tank housing 5 by support 4; Said cyclone separator 2 comprises cylinder chamber section 9, tapering chamber section 10, tailpipe section 11, underflow discharge zone 12, overflow pipe 7 and oil-polluted water import 8; Settling tank 5 is provided with oil drain out 3 and discharge outlet 6;

Fig. 3 has described the matching relationship between cyclone separator 2 and the oil-polluted water import 8, as seen from the figure, oil-polluted water import 8 is coupled along the tangential direction of cylinder chamber section 9, therefore, sewage can tangentially inject cylinder chamber section 9 by oil-polluted water import 8, thereby can enter cyclone pipe with the form of rotation.

Fig. 4 places the eddy flow sedimentation separation jar structure schematic diagram of settling tank outside for cyclone separator, the horizontal eddy flow sedimentation separation of Fig. 5 jar structure schematic diagram, obviously, as required, cyclone separator can be arranged in the settling tank chamber, also can be arranged on outside the settling tank, eddy flow sedimentation separation jar can be vertical, also can be horizontal.

The specific embodiment

The utility model is work like this: the sewage depended on pressure of oil-containing is entered in the cyclone separator by carrier pipe, form the eddy current of rotation at a high speed, under the effect of cyclone separator inner cone, centrifugal acceleration raises gradually, the centrifugal force phase that proportion is less then concentrates on the middle part of cyclone separator tube chamber, form light phase core, enter eddy flow sedimentation separation jar chamber top, discharge by oil drain out on the eddy flow sedimentation separation jar at last from rotational flow separation organ pipe overflow pipe; And bigger one the getting rid of mutually to cyclone separator chamber wall of proportion assembles the back from tailpipe section to enter eddy flow sedimentation separation jar bottom by the underflow discharge zone, discharges by the discharge outlet on the eddy flow sedimentation separation jar; Not only can immiscible profit be separated on the eddy flow sedimentation separation jar, also can quicken the sedimentation of solids in the oil-polluted water, the solid phase in the liquid is separated, thereby finish the purified treatment of oil-polluted water.
