Abstract

The invention discloses a fine filtration device for oily sewage twice treating by water aerosol filled outside a filter and belongs to oilfield equipment. The device comprises a three-phase separator, a water aerosol generator, a tangential jet orifice and a sewage secondary circulating system. The device is characterized in that oily sewage sequentially passes through filled water aerosol and the tangential jet orifice to enter into the three-phase separator. The oily sewage is separated in the three-phase separator through the adsorption action of microbubbles and filtration and screening of a membrane component, oil floating upwards to the top is discharged by an oil outlet, solid impurities deposited to the bottom are discharged by a slag-drip opening, a part of filtered sewage is extracted from the lower portion of the three-phase separator, after the water aerosol is generated again, the water aerosol and filtered sewage are returned to the three-phase separator, the sewage is further purified, and then the purified sewage is discharged from a water discharge port. Compared with devices in prior art, the device has the remarkable advantages that the separation is complete, the efficiency is high, the device has excellent popularization and application values, and the like.

Description

Nutsche filter is gone into the fine filtering device that the water filling aerosol is disposed oily(waste)water for twice outward
One, technical field:
The present invention relates to the oil equipment, particularly relate to a kind of nutsche filter and go into the fine filtering device that the water filling aerosol is disposed oily(waste)water for twice outward.
Two, background technology:
Utilize the characterization of adsorption and the little come-up characteristic of proportion of microbubble; Be applied to the disposal of oily(waste)water; More and more receive the favor of industry and adopt; Little air flotation technology under the prior art mainly is through microbubble generator, and aqueous vapor colloidal sol producer produces the suspension-s contain a large amount of microbubbles, through gas-distributing pipe, gas distribution pipe, qi-emitting hole spreading in the bottom of disposing oily(waste)water; Quicken and oil, water, slag three phase separation process that reinforcement is static and dynamic oily(waste)water, improve the efficient and the quality of oily(waste)water disposal.But still there is following deficiency in these technology, and the speed of little dissolved air flotation oily(waste)water and quality receive its aeration mode; Flow and bubble layout influence and limited, multiple static distribution devices such as the inverted T shape that occurs in the recent period, I shape, rake type gas pipe, and the dynamic diffusion device of guide vane rotational flow field; Though the solution of part the even problem of gas distribution, not but still leave big dead angle, and structure is comparatively not complicated; Be laid in the precision filter, all there are many difficulty in its installation, maintenance and maintenance.
Three, summary of the invention:
The objective of the invention is to above deficiency, provide a kind of gas distribution evenly, more thorough, simple in structure, the maintenance of oily water separation easily nutsche filter go into the fine filtering device that the water filling aerosol is disposed oily(waste)water for twice outward.
The present invention realizes that the technical scheme of its purpose is:
A kind of nutsche filter is gone into the fine filtering device that the water filling aerosol is disposed oily(waste)water for twice outward, comprises triphase separator, aqueous vapor colloidal sol producer, high-pressure hydraulic pump, peripheric jet flow mouth and secondary water circulation system, it is characterized in that oily(waste)water is before getting into triphase separator; Filling mixes by extracting filtered sewage via pump mouth in the triphase separator, through the aqueous vapor colloidal sol that aqueous vapor colloidal sol producer generates, mixes the common triphase separator that gets in back; Via the peripheric jet flow mouth; And under water conservancy diversion vane sheet limit is forced, form rotational flow field, with the three phase separation of dynamical fashion completion oily(waste)water, the process triphase separator filters the part of contaminated water after the separation; Before relief outlet is emitted; Extract out through pump mouth, form aqueous vapor colloidal sol, newly return in the triphase separator in the sewage after filtering separation via a plurality of peripheric jet flows are salty through aqueous vapor colloidal sol producer; Carry out secondary microbubble adsorption cleaning, form the secondary water circulation system.
Nutsche filter of the present invention is gone into fine filtering device that twice of water filling aerosol dispose oily(waste)water outward compared with prior art; Oily(waste)water promptly mixes with aqueous vapor colloidal sol before getting into nutsche filter; Make the microbubble uniform distribution, the absorption chance is more many, the time is longer, more thorough, and separate afterwards sewage re-injects aqueous vapor colloidal sol before discharge; Carry out secondary separation and dispose, make and discharge more cleaning of water body.The fine filtering device that nutsche filter of the present invention is here gone into twice disposal of water filling aerosol oily(waste)water outward also has the following advantages: 1, make aqueous vapor colloidal sol water for twice all from filtering isolating sewage in the triphase separator, i.e. water saving does not increase the processing water yield again; 2, the aqueous vapor colloidal sol of oily(waste)water and secondary water circulation system returns to three phase separation by the entering of peripheric jet flow mouth, forms rotational flow field, in dynamically, accomplishes the secondary-cleaned of three phase separation and filtration separation back sewage, and aqueous vapor colloidal sol is more evenly distributed, and usefulness is higher; 3, aqueous vapor colloidal sol go into to be annotated outside nutsche filter, has avoided going into to annotate the filtering function that the stirring of sediment is influenced membrane module by the bottom gas distribution pipe.
Thereby: the present invention has good application and popularization value.
Four, description of drawings:
Embodiment further specifies the present invention below in conjunction with accompanying drawing:
Fig. 1 goes into the right section synoptic diagram that the water filling aerosol is disposed the fine filtering device of oily(waste)water for twice outward for nutsche filter.
Among the figure: triphase separator 1, aqueous vapor colloidal sol producer 2, high-pressure hydraulic pump 3, opening for feed 4, pump mouth 5, peripheric jet flow mouth 6, water conservancy diversion vane sheet 7, membrane module 8, oil outlet 9, slag-drip opening 10, water port 11.
Five, embodiment:
As shown in Figure 1, triphase separator 1 inside is made up of membrane module 8, water conservancy diversion vane sheet 7, and the top is provided with oil outlet 9, the bottom is provided with water port 11; The bottom is provided with slag-drip opening 10, and the oily(waste)water of opening for feed 4 filtered isolating sewage with extracting through pump mouth 5 before getting into triphase separator 1; After the aqueous vapor colloidal sol mixing through 2 generations of aqueous vapor colloidal sol producer, get into triphase separator 1, via peripheric jet flow mouth 6 directive water conservancy diversion vane sheets 7; Force formation rotational flow field down in water conservancy diversion vane sheet 7 limits; Dynamically getting into membrane module 8 down, the solid matter in the oily(waste)water sinks and discharges through slag-drip opening 10, and oil droplet, oil droplet are by the absorption of the microbubble in aqueous vapor colloidal sol come-up; Discharge collection through oil outlet 9; The filtration membrane that water sees through membrane module 8 leaches, and filters isolating sewage and before discharging via water port 11, extracts out through pump mouth 5, generates aqueous vapor colloidal sol through aqueous vapor colloidal sol producer 2; Return the sewage that filters after separating by a plurality of peripheric jet flow mouths 6 again, further purify after discharge triphase separator 1 by water port 11.
Triphase separator 1 is launched initial nothing and is filtered isolating sewage water supply aerosol dispenser 2 preparation aqueous vapor colloidal sols, must implement in outer diversion source.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
