Abstract
The utility model relates to a fine filtering device for oily sewage subjected to twice treatment of water-injection aerosol outside a filter and belongs to oilfield equipment. The fine filtering device comprises a three-phase separator, a water aerosol generator, a tangential jet opening and a sewage secondary circulation system, and is characterized in that the oily sewage passes through the water-injection aerosol and then enters the three-phase separator through the tangential jet opening. The oily sewage is subjected to the filtering screening separation of a membrane assembly and the microbubble adsorption effect in the three-phase separator, oil upwards floating to the top and solid impurities settling to the bottom are respectively discharged out from an oil outlet and a slag discharging opening, filtered partial sewage is pumped out at the lower part of the three-phase separator and returns to the three-phase separator after forming the water aerosol again, and the sewage is further purified and is then discharged out through a water discharging opening. Compared with the prior art, the fine filtering device has the obvious advantages of thorough separation, high efficiency and the like, so good popularization and application values are realized.
Description
One, technical field:
The utility model relates to petroleum equipment, particularly relates to a kind of nutsche filter and enters the fine filtration device that the water filling aerosol is disposed oily(waste)water for twice outward.
Two, background technology:
Utilize 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 be subject to the favor of industry and adopt, little air flotation technology under the prior art mainly is to pass through microbubble generator, aqueous vapor colloidal sol producer produces the suspension that contains a large amount of microbubbles, by gas-distributing pipe, gas distribution pipe, qi-emitting hole spreading in the bottom of disposing oily(waste)water, accelerate and oil, water, slag three phase separation process that reinforcement is static and dynamic oily(waste)water, improve efficient and the quality of oily(waste)water disposal.But these technology still have the following disadvantages, the speed of little dissolved air flotation oily(waste)water and quality, be subjected to its aeration mode, flow and bubble influence of arrangement and limited, the 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 apparatus of guide vane rotational flow field, though the solution of part the even problem of gas distribution, not but still leave larger dead angle, and structure is comparatively not complicated, be laid in the fine filter, all there are many difficulty in its installation, maintenance and maintenance.
Three, summary of the invention:
The purpose of this utility model is for above deficiency, provide a kind of gas distribution evenly, more thorough, simple in structure, the maintenance of oily water separation easily nutsche filter enter the fine filtration device that the water filling aerosol is disposed oily(waste)water for twice outward.
The utility model realizes that the technical scheme of its purpose is:
A kind of nutsche filter enters the fine filtration device that the water filling aerosol is disposed oily(waste)water for twice outward, comprise 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 entering triphase separator, filling mixes by extracting sewage after filtering via pump mouth in the triphase separator, aqueous vapor colloidal sol by the generation of aqueous vapor colloidal sol producer, jointly enter triphase separator after the mixing, via the peripheric jet flow mouth, and force lower formation rotational flow field in water conservancy diversion vane sheet limit, finish the three phase separation of oily(waste)water with dynamical fashion, part of contaminated water after filtration separates through triphase separator, before relief outlet is emitted, extract out through pump mouth, form aqueous vapor colloidal sol by aqueous vapor colloidal sol producer, newly return in the triphase separator in filtering the sewage after separating via a plurality of peripheric jet flows are salty, carry out secondary microbubble adsorption cleaning, form the Secondary water circulation system.
Nutsche filter of the present utility model enters fine filtration device that twice of water filling aerosol dispose oily(waste)water outward compared with prior art, oily(waste)water namely mixes with aqueous vapor colloidal sol before entering nutsche filter, microbubble is evenly distributed, adsorption machine can be more, the time is longer, more thorough, sewage re-injects aqueous vapor colloidal sol after separating before discharge, carry out secondary separation and dispose, make the discharge water body cleaner.Nutsche filter of the present utility model enters twice of water filling aerosol outward and disposes the fine filtration device of oily(waste)water and also have the following advantages herein: 1, make aqueous vapor colloidal sol water for twice all from filtering the sewage that separates in the triphase separator, i.e. water saving does not increase again the processing water yield; 2, the aqueous vapor colloidal sol of oily(waste)water and Secondary water circulation system returns to three phase separation and enters by the peripheric jet flow mouth, forms rotational flow field, in dynamically, finish three phase separation and filter separate after the secondary-cleaned of sewage, aqueous vapor colloidal sol is more evenly distributed, usefulness is higher; 3, aqueous vapor colloidal sol enters to annotate outside nutsche filter, has avoided entering notes affect membrane module on the stirring of sediment filtering function by the bottom gas distribution pipe.
Thereby: the utlity model has good application and popularization value.
Four, description of drawings:
Embodiment further specifies the utility model below in conjunction with accompanying drawing:
Fig. 1 is that nutsche filter enters the right section synoptic diagram that the water filling aerosol is disposed the fine filtration device of oily(waste)water for twice outward.
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 by membrane module 8, water conservancy diversion vane sheet 7 forms, 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, the oily(waste)water of opening for feed 4 is before entering triphase separator 1, with the sewage that separates by pump mouth 5 extraction filtrations, after the aqueous vapor colloidal sol mixing by 2 generations of aqueous vapor colloidal sol producer, enter triphase separator 1, via peripheric jet flow mouth 6 directive water conservancy diversion vane sheets 7, force lower formation rotational flow field in water conservancy diversion vane sheet 7 limits, under dynamically, enter membrane module 8, solid matter in the oily(waste)water sinks and discharges through slag-drip opening 10, oil droplet, oil droplet is 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, filtering the sewage that separates extracts out by pump mouth 5 before discharging via water port 11, generate 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 by discharging triphase separator 1 by water port 11.
Triphase separator 1 is enabled initial without filtering the sewage water supply aerosol dispenser 2 preparation aqueous vapor colloidal sols that separate, and must implement in outer diversion source.
Except the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
