Ozone microbubble floatation thickening device of the present utility model is the one of pressure air-dissolving air-float, this by microbubble with
Micro-floccule concurrently forms and combines, and then the process jointly growing into band gas flco is referred to as " copolymerization ".Bubble is the least, more
It is easily accessible flco, or quilt wadding catches, thus form stable copolymerization flco.It discharges the micro-of highly dense in time delay
Bubble, when being sufficiently mixed with mixed reaction water of offeing medicine, both grow up simultaneously, and the band gas flco so formed was floating
The advantages such as Cheng Zhong, has floating fast, and scum silica frost is stable, and the tolerance of consumption is few.
The design principle of ozone microbubble floatation thickening device of the present utility model is: utilize eddy current three-phase blender,
Waste water is directly added into gas and medicament, completes molten gas and stirring simultaneously, finally realize self-skimming.Eddy current three-phase blender collection is molten
The stirring of gas, differential, flco aerating, granule attachment, the generation of molten gas nucleus and bubble release function are in one.Its workflow bag
Include: 2. the highest pressure solution gas stretch medicament and be 3. sufficiently stirred for 4. nucleus and form 5. bubble and condense 6. flco and merge that 8. 7. scum silica frost is quenched follows
Ring flocculates.Eddy current three-phase blender and the difference of tradition air-dissolving air-float: maximally utilise chemical agent;Form ultralight hollow
Flco, makes flco moisture content and proportion reduce, and flco is solid and has and the strongest goes up i, beneficially self-skimming voluntarily.
As in figure 2 it is shown, the work process of ozone microbubble floatation thickening device of the present utility model is: (1) intakes: use
Waste water is formed eddy current from regulating reservoir input multi-stage vortex three-phase blender by pressurization intake pump;(2) aerating/dosing mixing is stirred
Mix: in multi-stage vortex three-phase blender, pressurized ozone being directly dissolved in incoming waste water, and then chemical agent is directly thrown
Add in molten gas-liquid, complete medicament and mix with contaminant particle (solid), water, gas three-phase;Agent molecule is initially coil-shape, whirlpool
Flow and agent molecule stretching is put forward effect, be sufficiently stirred for;(3) eddy current produces microbubble and implants in float: medicament and pollutant
After grain, water, gas mixture are discharged in the contact chamber A of reactive tank, then weir flow enters separation chamber B, and eddy current produces microbubble and plants
Entering in pollutant, pollutant are captured, and flco is formed and floats;(4) release float;(5) slag remover is utilized to automatically remove floating
Slag;Scum silica frost (mud) enters dreg collecting slot 6 and collects or process;Collect clear water at clear water collecting chamber C, reaction tank bottom discharge.
Ozone microbubble floatation thickening device of the present utility model, produces microbubble by eddy current three-phase blender, adheres to
As carrier in float, form the gas-solid mixture that density is lighter than water, float to the water surface, so that suspended contamination and water
Separate;Can effectively remove solid suspended particles, oils, turbidity and the Organic substance etc. in complex wastewater;Effectively facilitate pollutant
Efficient process, reach outstanding effects of energy saving and emission reduction.
Ozone microbubble floatation thickening device of the present utility model quotes external eddy current three-phase hybrid technology, at eddy current three-phase
In blender, current produce fierce eddy current, thus reach medicament, water, the differential stirring of gas and mixing.Use bypass ascending pipe
Flocculant is injected the raw water tubes (i.e. water inlet pipe) import department's (i.e. lateral inflow mouth of eddy current three-phase blender close to reaction zone
Place), the caliber of bypass ascending pipe is more small than the caliber of raw water tubes, and the aperture of bypass ascending pipe is perpendicular to former with the biggest speed
The direction injection of water pipe current, flocculant is injected former water flow turbulence intensity maximum when (in breach and near nodal position
Put), the most easily quickly mix with former water.Flocculant mixing can be divided into three sections, and first paragraph is potential barrier section, jet in this section
Flow velocity is constant, and jet starts water former with surrounding and mixes;Second segment is deviation section, in raw water tubes under the effect of current jet to water
Flow path direction deviation, and mix with former water further;3rd section is whirlpool section, if there is carried interest whirlpool above the water flow section of jet
Whirlpool, makes jet spread rapidly, is thoroughly mixed with former water.In a word, through breach and node, there is violent convergence, disperse, turn
To, tear, therefore forming countless little whirlpool, make medium turbulent fluctuation and Surface Renewal speed greatly speed up, liquid-film resistance is greatly lowered, institute
The highest with mass transfer rate.
The feature of ozone microbubble floatation thickening device of the present utility model is as follows:
1, high pressure solution gas: pressurized ozone 100% is dissolved in and becomes a mandarin in sewage, the most pneumatically supported bubble attachment reason
Opinion, this step realizes contaminant molecule and contacts gas attachment under dissolved state with the least limit of bubble;
2, medicament is stretched: generally polymer is in strand when adding and kinks agglomerating state, and this product is distinctive efficiently
Blender can will kink the stretching of agglomerating strand and become strip strand, makes agent molecule chain institute electrically charged can fully be exposed profit
With, reduce waste;
3, be sufficiently stirred for: multi-stage, efficient blender by various effective speeds realize medicament and pollutant be fully contacted with
Mixing.Enable pollutant by entrained by agent molecule chain and the electric charge that exposes adsorbs securely;
4, scum silica frost is formed: along with the reduction of pressure, the gas of the dissolved gradually forms countless pole by pollutant flco
Thin bubble, is grown directly upon among mud flco;
5, bubble cohesion: bubble constantly merges expansion, produces the granule of spongy flco;
6, flco merges: during flocs float, the rapid coalescence of tiny flco, and bubble the most drastically expands simultaneously,
Tie up the space of flco internal clearance water, make flco moisture content and proportion reduce further, flco solid and have the strongest voluntarily
Upper i;
7, quenched scum silica frost: scum silica frost floats up to Chi Mianshang, mutually piles up, is bonded to scum silica frost blanket, forms entirety and floats, moisture content
Reduce further;
8, effluent collection: the water outlet of floatation thickening is discharged by reaction tank bottom, enters collector pipe and collects clear water zone;
9, scum layer controls: controls water outlet liquid level by regulation weir plate, thus controls the thickness of scum layer.
