Description
Technical field
The present invention relates to a kind of environmental protection equipment, particularly a kind of sequence enters formula air-floating apparatus.
Background technology
Air supporting 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 to be struck off, thus realize the process of solid-liquid or Liquid liquid Separation.
Air supporting, as Wastewater Pretreatment oil removing system, is widely used in every field, especially in the industries such as iron and steel, petrochemical industry, mechanical workout, papermaking.But the concentration adopting one-level air supporting reaction to be also not enough to allow the pollution factor such as oil, suspended substance be removed to follow-up facility can to bear, for reaching the object continuing to reduce pollutent, therefore adopts the method carrying out processing that two air supportings to be together in series usually.Although object reaches, shortcoming also clearly:
1) floor space is large, and all need independently coagulation reaction tank and flocculation tank before two air supportings, centre also needs pipeline to connect, and floor space is too large;
2) energy consumption is high.Two air supportings are all equipped with independently reflux pump, agitator, slag scraper etc.;
3) chemical feeding quantity is many, and two air supportings need stage agent addition, and chemical feeding quantity is larger;
4) aspects such as high, same two equipment slave units, material, controls are invested all higher.
Therefore, in view of some problems existing for the air supporting of existing waste water two-stage, a kind of equipment meeting Wastewater Pretreatment function of special needs, makes up the weak point of existing two-stage series connection airfloat equipment.
Summary of the invention
The object of the invention is the defect for existing in prior art, providing a kind of sequence to enter formula air-floating apparatus.When reaching existing two-stage series connection air supporting to oil and the equal removal effect of the pollution factor such as suspended substance, the pneumatically supported deficiency of existing two-stage series connection effectively can be made up.The present invention mainly comprises: casing, aerator, return line, slag scraper, helix transporting device, convergent divergent channel, air dissolved pump, it is characterized in that described sequence enters formula air-floating apparatus is non-pressure vessel, casing is skeleton construction, aerator is vertically mounted on casing front end, the front end of casing is provided with solarization air cell, bottom is provided with return line, return line communicates with solarization air cell, aerator hollow design, inside there is hollow pipeline, hollow pipeline top communicates with air, bottom communicates with rotary hollow impeller, the hollow impellers high speed rotating of aerator forms the vacuum zone of tiny structure in solarization air cell, the top of air from hollow pipeline is sucked, micro-bubble is produced through the cutting of Cavltation aerator high speed rotating.Micro-bubble and the waste water entered from casing front end solarization air cell, rise to liquid level surface by reacted oil and suspended substance support.Slag scraper is arranged on the top in the middle of casing, slag scraper is connected with the scum silica frost receiving tank of helix transporting device, scum silica frost strikes off in scum silica frost receiving tank through slag scraper, discharged by spiral conveyer, bottom in the middle of casing is provided with convergent divergent channel, air dissolved pump is equipped with in the rear end of casing, air dissolved pump is connected with convergent divergent channel through pipeline, the waste water of the same for part water outlet pars infrasegmentalis overcurrent mixes by air dissolved pump again, under high pressure form dissolved air water after mixing to discharge through convergent divergent channel, allow micro-bubble that remaining pollutent is risen to liquid level surface.Waste water flow to back segment from bottom, and oil and suspended substance are floated up to liquid level surface and again struck off by slag scraper by dissolved air water mixing through producing with air dissolved pump further.Casing front end solarization air cell is provided with sewage input aperture, and box back is provided with the clear water relief outlet of adjustable overflow weir.
Described casing by carbon steel or stainless steel or concrete for making, through rotproofing.
The described slag scraper made by materials such as stainless steel, rubber, superpolymer is driven by motor, around the sprocket wheel cycle rotation at two ends, air-floating apparatus is provided with two cover slag scrapers, and a driven by motor two overlaps slag scraper, and the scum silica frost receiving tank of helix transporting device is arranged on the below of slag scraper.
Describedly mix sufficient convergent divergent channel for air with water and made by carbon steel.
Progressive air flotation of the present invention has following advantage relative to existing two-stage series connection airfloat equipment:
1) adopt intensive design, merged the pneumatically supported effect of two-stage, optimized and combined in a set of equipment, saved floor space.
2) adopt a driven by motor two to overlap slag scraper, compared with the pneumatically supported independent setting of two-stage, save energy consumption, saved running cost.
3) adopting a dosing, between two sections of air supportings, there is no violent disturbance, avoiding established small flco broken before section after entering, because this reducing chemical feeding quantity.
4) compact design has saved material, saves intermediate connection tube road, valve etc. simultaneously.
5) operational management is convenient, and the parts do not needed repairing in groove, do not have easily to block in traditional air-dissolving air-float, need the release head of back flushing, and whole system normal pressure runs.
Advantage of the present invention adopts intensive design, merge the pneumatically supported effect of two-stage, saved floor occupying area, decrease chemical feeding quantity, simple to operate, easy to maintenance, applied widely, removal efficiency is high, can be applied to the pretreatment technology of all trades and professions of wastewater treatment.
