Description
Technical field
The utility model relates to oilfield, specifically the multistage single pump air-float degreasing device of a kind of gallery type.
Background technology
By Bubble-floating Method in water treatment comes from flotation technology, it is the micro-bubble of height of formation dispersion in water, adhere to solid or the liquid particle of hydrophobic group in waste water, form water-gas-particle three-phase mixed system, after particle adhesion bubble, form apparent density be less than the flco of water and float to the water surface, form scum layer and struck off, thus realize the process of solid-liquid or Liquid liquid Separation.Flotation technology is widely used in multiple fields such as mine, papermaking, chemical industry, oil, and embodied advanced processing performance, very outstanding effect can be played for the separation between similar density material, application main purpose for By Bubble-floating Method in petrochemical industry is, to the recovery containing surplus value material and water purification two aspects.
Air-floating apparatus at present for oil field extracted waste water process mostly is one-level, in the operational process of equipment to water in oil-containing sepn process for once, in dissolved air water and water, the contact efficiency of oil droplet is low, causes poor processing effect.And current air-floating apparatus structure is very single, be difficult to allow treatment effect reach qualitative leap by transformation in existing structure.
Summary of the invention
In order to overcome the deficiency of the existing air-floating apparatus poor processing effect for wastewater treatment, the utility model provides a kind of gallery type multistage single pump air-float degreasing device, this device adopts stage trapping, multistage recovery, realizes the function setting up standby multiple-stage treatment, makes treatment effect better.
The technical solution of the utility model is: the multistage single pump air-float degreasing device of a kind of gallery type, comprise casing, described box house is become the classification casing communicated bottom several by vertical baffle for separating, all water distributor is equipped with in each classification casing, and water distributor is connected with water inlet pipe after connecting successively, the bottom of classification casing is connected with mud valve by pipeline; Casing is externally connected to dissolving, dissolving connects several dissolved air releases, and dissolved air release is placed in classification casing respectively, and classification casing top is all fixed with oil-collecting device.
Described casing top-side is fixed with collection tank, and the oil-collecting device on described classification casing is all connected with collection tank.
Variable valve is provided with between described dissolving and dissolved air release.
The utility model has following beneficial effect: owing to taking such scheme, casing inner route clapboard is divided into several classification casings, be provided with water distributor in classification casing, and every grade of casing is all provided with dissolved air release, the contact probability of tiny oil droplets in dissolved air water and water can be expanded like this; All oil-collecting device is provided with in every grade of casing, the multistage recovery of floating material can be realized when water is run in equipment, so can ensure the recovery ratio of floating material to greatest extent, floating material very first time after floating just can be recovered, avoid material after floating to surface due to bubbles burst cause density and aqueous phase near, thus boundary is unclear, be difficult to be separated.Meanwhile, every grade of bottom half is provided with separately independently mud valve, independent spoil disposal of can fixing a point, so that can the deposition of settled sludge and outer row.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By shown in Fig. 1 to Fig. 3, the multistage single pump air-float degreasing device of a kind of gallery type, comprise casing 1, described casing 1 inside is become the classification casing communicated bottom several by vertical baffle for separating, all be equipped with water distributor 8 in each classification casing, the water distributor 8 in each classification casing is connected with water inlet pipe after connecting successively.The bottom of each classification casing is tapered, so that can the deposition of settled sludge and outer row, the bottom of level casing be equipped with mud discharging device, each mud discharging device is equipped with mud valve 14.Casing 1 is externally connected to dissolving 11, and molten cylinder 11 is connected with air dissolved pump 2, dissolving 11 connects several dissolved air releases 3, and each dissolved air release 3 is placed in each classification casing respectively, is provided with variable valve 12 between dissolving 11 and dissolved air release 3.Each classification casing top is all fixed with oil-collecting device 10, and casing 1 top-side is fixed with collection tank 13, and the oil-collecting device 10 on described classification casing is all connected with collection tank 13, and last step casing edge is provided with overflow weir 9.Described air dissolved pump 2, oil-collecting device 10 control by power distribution cabinet 6.
When carrying out water treatment, first water enters casing 1 by water-in, water distribution is carried out by water distributor 8 in first step casing, object is water can be distributed to more uniformly in limited casing, to avoid the head pressure entrained by water to make water accelerate through casing, but complete whole sepn process slowly after buffering.Dissolved air water is discharged in the region that water distributes by dissolved air release 3 below water distributor 8 uniformly, the fusion of water and dissolved air water is completed in this region, just the mixture of global density much smaller than water can be formed after microbubble in the process merged in dissolved air water contacts with oil droplet, thus accelerate the speed of oil droplet floating, along with water passing through in casing, oil droplet in water is separated with former water gradually, finally float to the water surface, realize the oil slick after being separated by oil-collecting device 10, flow into overall collection tank 13.Casing at different levels is basically identical structure, just operationally the adjustment of oil-collecting device 10 highly needs to regulate according to liquid level situation, thus ensure that collected oil slick can reach comparatively reasonably water ratio, the too low meeting of its water ratio causes received oil slick mobility poor, be unfavorable for outer row, its water ratio is too high, can cause waste, reduces bulk treatment amount.The adjustment of oil-collecting device 10 also needs reference operating temperature, the factors such as oleaginousness, and the concrete height that regulates can outer minimum flow rate of arranging be as the criterion smoothly with oil slick, and oil-collecting device 10 at different levels is regulating on height in the trend progressively reduced generally.Complete the water after separation at different levels to be flowed out by the overflow weir 9 of last step casing, finally complete whole sepn process.
Mud entrained in water or suspended substance isodensity are greater than the solid pollutant of water, progressively can deposit in the cone bucket structure of bottom half with water (flow) direction in sepn process, but due to the difference of solid pollution properties and density, concrete deposition position is difficult to determine, so be all provided with mud valve 14 at bottom half at different levels, the deposition position of mud is determined by discharging sampling on a small quantity, thus realize the point discharge of equipment mud, avoid when ensureing mud normal discharge wasting a large amount of former water.
The air dissolved pump of this device is fetched water from water outlet, boosted after molten gas by air dissolved pump 2 and enter dissolving 11, after brief stay voltage stabilizing, the dissolved air release 3 in casing at different levels is entered at dissolving 11, variable valve 12 is installed between dissolving 11 and reliever at different levels 3, for regulating the pressure of dissolving 11, best molten gas effect is ensured with this, interlock is needed between each variable valve 12, avoid the reflux ratio between each casing inconsistent, in particular cases also can according to the reflux ratio of actual production demand differenceization casing at different levels, be as the criterion so that desirable treatment effect can be reached.
