Description
Technical field
The utility model relates to a kind of air-flotation process micro-bubble generation device, is mainly used in providing a large amount of micro bubbles required in air-flotation process technique.Owing to having compact construction, treatment capacity is large, gas effciency is high, convenient for installation and maintenance and the advantages such as steady in a long-term operations can be realized, especially applicable offshore oilfield recovered water air-flotation process micro bubble generation device.
Background technology
The micro bubble injecting a large amount of high dispersing in sewage is pointed in air supporting, make it collide as carrier and particulate contaminants (as suspended solids (SS), oil droplet etc.) in floating-upward process to adhere to, promote that forming density is less than the particle-micro bubble adherend of water thus accelerates oil water separation process.The key of air-flotation process technology and prerequisite are the micro bubbles having abundant amount, be evenly distributed, and therefore the investigation and application of micro bubble becomes hot issue just gradually.Up to now, it is several that the producing method of micro bubble has molten gas bubble, bleed manufactures bubble, microporous medium foaming, electrolysis bubble etc.
(1) molten gas bubble
Molten gas bubble refers to and under pressure excessive gas dissolving is formed saturated dissolved air water in water, and after step-down, gas discharges the process water being formed and be rich in microbubble from process water.The bubble size less (10 ~ 120 μm) that the method produces, and there is the advantages such as unit construction principle is simple, easy to maintenance, apply comparatively extensive.But because in use floor space is large, and required dissolved-air pressure is higher, and molten tolerance is less than normal, is unfavorable for further popularization.
The mode that the multiphase flow pump adopting molten air elutriation to go out principle manufactures bubble solves floor space greatly, molten narrow-minded defect.Be with the difference that tradition molten gas bubble is maximum, use multiphase flow pump to replace dissolving in pressured air-dissolving device in pump, complete pressure air-dissolving process.The micro bubble particle diameter that the molten gas of multiphase flow pump generates is substantially at about 30 μm, and system configuration is simple, and control, debug simply effectively, gas-liquid mixed degree is high.But the disposable input cost of multiphase flow pump is comparatively large, and power consumption and maintenance cost high.Multiphase flow pump known at present has U.S. Exterran
tMthe ONYX-Micro Bubble pump of company, Siemens Brise
tMiGF pump, German Edur air dissolved pump, Japanese NIKUNI turbulence pump etc., wherein the kind of German Edur air dissolved pump is enriched the most, is most widely used.
(2) bleed manufactures bubble
The principle that bleed manufactures bubble is the underbalance effect suction gas utilizing impeller high speed rotating or reducing Venturi tube (being correspondingly called impeller rotary-cut method and fluid jet) jet to produce, and gas is pulverized under vane rotary or fluid shearing effect and forms micro bubble.The main shortcoming of vane rotary method is that air is pulverized abundant not, and the bubble particle size of formation is comparatively large, is generally all not less than 0.1mm, and the high-speed rotary of impeller easily causes the required Oil Droplet Breakup be separated, and makes it more be difficult to be separated; The inner movement-less part of fluid jet, energy expenditure is lower, but micro bubble generation quality affects comparatively large by change in flow, not easily produce stable and uniform micro bubble, and the micro bubble particle diameter produced is higher than impeller rotary-cut method.
(3) electrolysis bubble
The principle of electrolysis bubble assigns in water by positive and negative different electrode, under galvanic effect, separates out micro bubble by the electrolysis such as polarization, electrophoresis, redox reaction of electrolysis, particle.Electrolysis is separated out the micro bubble particle diameter produced and is generally all less than 60 μm, and there will not be turbulent flow in electrolytic process, and to sewage load variations strong adaptability.But electrolysis separates out micro bubble to battery lead plate loss comparatively greatly, and operation and maintenance cost is higher, is not suitable for promoting on a large scale.
(4) microporous medium foaming
Microporous medium foaming mainly utilizes the pressure difference between gas-liquid two-phase, and the gas that pressure is higher forms fine air-flow by microporous medium, forms micro bubble and disperse in the liquid phase under the shearing souring of liquid phase.The method structure and working principle is fairly simple, and power consumption is few, and the porosity of microporous medium and pressure field can be selected to regulate the size of the micro bubble produced.Microporous medium foaming technique because of produced micro bubble quality compared with high, energy consumption compared with low, floor space is little and without dynamic equipment, receive the concern of people gradually.
The people such as He Xulong mention a kind of micro-bubble generator in patent CN2304456 Y, and wherein air cavity part forms by circular fiber cloth is stacking, and two ends utilize pressing plate press seal.Gas under pressure enters air cavity by uptake, and then sprays in liquid by the gap of circular fiber cloth, forms a large amount of nebulous micro bubble, can change the size producing bubble by the degree of tightness between setting nut and nut.But, because whole air cavity forms by cloth material is stacking, when the comparison of ingredients of dirty water pollutant is complicated, often easily causes cloth to block because of corrosion or ponding, safeguard that replacement frequency is higher.In addition, although adopt stack manner can change pore size by clamping platen, can not ensure that the pore size between cloth is even, and then the micro bubble produced is second-rate, affects air flotation effect.
The people such as Ningbo Veritas-msi Multiphase Flow Equipment Co., Ltd Ma Lifeng propose a kind of generating unit with micro bubble oil-containing water in patent CN101347687 B, nucleus equipment gas-solution water generator is made up of the whirlwind-type dissolved air water generating pipe of column shape container and Qi Nei, and the latter comprises again the cylindrical section microporous pipe portion with the cylindrical seal pipe portion of tangential flow guiding mouth, conical sealed tube portion and bottom.The final effect that structure design reaches is, enter into cylindrical section microporous pipe portion oily(waste)water to rotate in the shape of a spiral, and the compressed gas in inlet chamber is through the cylindrical section micropore tube wall with countless small constant aperture, produce the micro bubble of the size that conforms with the regulations in a large number, and finally go out sap cavity from the opening inflow first bottom whirlwind-type dissolved air water generating pipe.But microporous pipe portion in this patent adopts micropore metal sintered pipes or micropore metal laser drill or micropore ceramic tube, the bubble diameter average produced under its operating parameters condition used is bigger than normal and air pocket quantity is more, and therefore after gas-solution water generator, series connection employs an air pocket remover.In addition, the structure design of " microporous pipe inner chamber is leaked water, exocoel flat " that the program is taked makes whole device processes amount less than normal, have to the parallel running of many whirlwind-type dissolved air water generating pipes when oily water treatment amount is larger, thus cause that the installation weight of industrial application level is heavier, floor space is also comparatively large, substantially loses the advantage compared with building generating unit with pressure air-dissolving bubble.
China University of Geosciences poplar is righteous and courageous waits people in patent CN101549257A, propose a kind of bubble generator: algae-containing seawater flows through microporous membrane pipe by direct current mode, pressurized air is sent to annular cavity by inflatable interface simultaneously, and entered in microporous membrane pipe by the micropore on microporous membrane pipe and form fine air-flow, fine air-flow forms micro bubble and enters the mixing tank of pipeline configuration with fluid under swiftly flowing fluid shearing effect.Program structure suction culvert adopts craspedodrome form, and the impurity such as many miscellaneous granules in fluid, fluid can be caused to flow uneven, fluid permeability is even caused to enter annular cavity, simultaneously admission passage adopts two air intake, cause gas annular cavity internal pressure and flow velocity uneven, cause fine air-flow thickness uneven, bubble diameter span is large, causes produced micro bubble second-rate.
The people such as Kunming University of Science and Technology Lee Zhejiang elder brother mention a kind of microvesicle generators microporous foam technology combined with bubbling jet technology in patent CN201565361U.Ore pulp enters into interior pipe by microvesicle generators divergent nozzle and forms jet, and because reducing pressure by regulating flow principle produces negative pressure in pipe, under suction function, air is inhaled into taper air cavity, with after micropore in microporous pipe section enter pipe formation micro bubble in liquid.Suction gas after the negative pressure that this device mainly relies on high speed ore pulp to be formed in interior pipe, therefore in flow one timing, accurately cannot control the pressure reduction of air cavity and water cavity, the bubble diameter produced is larger and uneven.
Appoint ease in patent CN201644234U, mention the tube bundle type microporous bubble mixer of a kind of ore dressing ore pulp inflation mineralising.In the apparatus, it is inner that ore pulp enters into the fluid pipeline be made up of many microporous pipe, high pressure gas enter into the air cavity between cylindrical shell and microporous pipe by cylinder lateral wall, and under inside and outside differential pressure effect, gas permeation micropore forms fine air-flow and enters in ore pulp, make ore pulp inflate mineralising.This unit capacity is comparatively large, but because of liquid inlet employing craspedodrome circuit, the inner ore pulp of microporous pipe reduces in Bottomhole pressure distance, and the micro bubble quantity be dissolved in ore pulp will reduce.
Clean Water Technology company of the U.S. propose in patent US20040178152A1 a kind of liquid-solid-gas mixing tank (Liquid Solid Gax Mixer, LSGM).Liquid enters into reception cavity by tangential water inlet pipe and is full of whole chamber, is entered into the annular chamber surrounding of LSGM subsequently by perforated tube.Meanwhile, gas is entered in internal capillary pipe by top inlet mouth.Under inside and outside differential pressure effect, gas enters into annular chamber surrounding through micropore tube wall, is formed after being rich in the mixing liquid of micro bubble and discharge through bottom discharge mouth under hydrocyclone shearing action.But annular chamber surrounding height is greater than reception chamber height in this patent, the liquid cyclone intensity caused in annular chamber surrounding weakens from top to bottom gradually, namely liquid reduces gradually to microporous pipe boundary shear stress, and shearing force directly affects the size of micro bubble, thus make the micro bubble particle diameter of formation bigger than normal.Disclosed in the said firm, data shows, often adopt in practical work process more than Pyatyi liquid-solid-gas mixing tank series connection.
