Description
Technical field
The present invention relates to a kind of air supporting method and carry out the water treatment facilities of solid-liquid or the separation of liquid liquid, be mainly used in the air-float purification water treatment process.
Background technology
The air supporting method is that Xiang Shuizhong injects a large amount of microbubbles; The solid or the contaminant particle that make density in itself and water or the waste water approach water stick, and form the air float body of density less than water, under buoyancy function; Float to water surface formation scum silica frost, carry out a kind of water technology that solid-liquid or liquid liquid separate.It is mainly used in removes relative density less than 1 suspension, wad a quilt with cotton grain, oils, fat etc. from natural water or waste water.
The method that the air-float water treatment technology produces according to microbubble is divided into loose gas air supporting method, pressure air-dissolving air-float method and electrolytic gas float glass process etc.Wherein fine, the epigranular of the generation bubble that has of pressure air-dissolving air-float method, big, the low cost and other advantages of closeness obviously are superior to other air-float method, are used widely.But there are some shortcoming in traditional air flotation device of pressure air-dissolved; Its device must dispose air compressor, pressure air-dissolving tank, pressure balance control system etc.Equipment is huge, and the air compressor machine noise is big etc.And the gas air supporting method of loosing utilizes impeller of pump that the air in the liquid is carried out high speed shear, mixing, pulverizing, forms tiny bubble.Though device therefor is few, the bubble of its generation is bigger, and daf efficiency is lower.
Summary of the invention
The objective of the invention is to avoid the deficiency of prior art to provide a kind of microbubble to dissolve the gas generating means.Obtain the floating optimum level that dissolves gas-liquid " amount " and " matter " aspect of institute's aerogenesis.
For realizing above-mentioned purpose; The technical scheme that the present invention takes is: a kind of microbubble dissolves the gas-liquid generating means; Its main feature is to include return duct and is communicated with the gas-liquid mixing pump water inlet, and air inlet is provided with flowmeter and air inflow control valve, and delivery port communicating pipe is communicated with the inlet of Gas dissolving pipe; The outlet of Gas dissolving pipe is communicated with dissolved air release through the air supporting hydraulic control valve, between the outlet of Gas dissolving pipe and air supporting hydraulic control valve, is provided with Pressure gauge.
Described microbubble dissolves the gas generating means, and described Gas dissolving pipe includes leading portion packing area and back segment voltage stabilizing district, is provided with separation net between leading portion packing area and the back segment voltage stabilizing district; Described water inlet communicating pipe is inserted in the feed liquor end cap that the leading portion packing area is provided with, and is provided with fluffy pouring head at the mouth of pipe; Fluffy pouring head has filler; On the leading portion packing area, also be provided with air bleeding valve; Lower end in back segment voltage stabilizing district is provided with molten gas liquid outlet.
Described microbubble dissolves the gas generating means, and the filler of described packing area dissolves gas filler or cascade ring, Pall ring, multiaspect hollow ball etc. for the X type.
Described microbubble dissolves the gas generating means, and molten gas filler of described X type or cascade ring, Pall ring, multiaspect hollow ball etc. are for having the PVC cavity ring of bigger serface.
Described microbubble dissolves the gas generating means, and the operating pressure of described Gas dissolving pipe is 0.3 to 0.4Mpa.
Described microbubble dissolves the gas generating means, and the pressure of described dissolved air release is 0.1-0.3Mpa.
Gas-liquid mixing pump has gas-liquid delivery and sucks the air function; And with the impeller of the air water mixed liquor that sucks through gas-liquid mixing pump; It is carried out high speed pulverize, shear, mix once more, become the mixing material that contains a large amount of tiny bubbles, and with in its input Gas dissolving pipe.
In Gas dissolving pipe, the molten gas filler of mixed liquor process Large ratio surface, liquid film turbulent fluctuation and Surface Renewal, speed is accelerated greatly, and under 0.3 to 0.4Mpa pressure, air further obtains dissolving in water, obtains maximum molten gas effect.Discharge through the dissolved air release decompression then, obtain 20 microns atomic minute bubbles in the left and right sides.
In fact the performance indications of data represented air-floating apparatus such as air supporting producing water ratio, dissolved air amount, outgassing rate on aspect " amount ", the fine and closely woven degree of institute's aerogenesis bubble then is the performance indications of " matter " aspect.If bubble is big, the rate of climb is fast, and the disturbance water body is just violent, and to smaller particles impurity in the liquid and the easy loose wadding grain that is crashed, its effect is just poor.Self-evident, matter is made a gesture of measuring even more important, and more difficulty obtains.The present invention tries hard to obtain the optimum efficiency of " amount " and " matter " exactly, makes device have higher practicality, is the optimization and the combination of diffusing gas air supporting method and dissolved air flotation.
The invention has the beneficial effects as follows the advantage of collection pressure air-dissolving air-float method and air-spreading and dissolving type method, solve its deficiency, optimize and combination.Utilize the impeller of gas-liquid mixing pump will shear, mix with the water inhaled air earlier.It is fused further in Gas dissolving pipe, to carry out gas-liquid again, and its required pressure has omitted air compressor fully from gas-liquid mixing pump, high pressure dissolving etc.Make the adjustment and the equipment configuration of the gas-liquid pressure balance in the system become simple, make input cost and operating cost lower.
This device input cost is merely 1/4th to 1/5th of traditional air-floating apparatus.Its operating cost is also well below conventional apparatus.
