Description
Technical field
The utility model belongs to the purification of water quality field, refers to a kind of absorption property that utilizes microbubble and the floating power that goes up especially, carries out the water correction plant that river behind the aggregation or sewage carry out solid-liquid separation with adding coagulating agent.
Technical background
Present air-float purifier both domestic and external mainly contains by air-breathing three kinds of air-dissolved air supporting and the malleation inflatable air-dissolving air-floats of inducing of wheel speed negative inspiratory pressure formula induction flotation, injection or jet.First kind of air supporting mainly causes negative inspiratory pressure by electric motor driving impeller high speed rotating, and then gas is dissolved in the water; Spray or jet is air-breathing when inducing air-dissolved air supporting mainly by jet-pump high-velocity jet liquid stream that formed vacuum pressure comes air-breathing.The common result that air supporting produced of these two kinds of air-breathing modes of difference is that formed microbubble particle diameter is bigger, be 30-100 μ m, bubble is big, and number is few, allow the suspended particle that flows through in the water run away easily, cause effluent quality not reach design requirements,, just must increase the dissolved air water amount as meeting design requirement, pressure boost, prolong the residence time etc., cause volume of equipment big, operation electric load height; The third malleation inflatable air-dissolving air-float routine take the form of one vertical, volume is big and be equipped with in the high pressure solution gas cylinder of filler, when injecting high pressure water, external pressure adds pressurized air, produce dissolved air water through contacting with filler, discharge microbubble through reliever then, bubble diameter generally is 30-50 μ m, and it is that power is big, bubble big, the unit volume processing water yield is little, effluent quality is poor, power consumption is big, cost is high that the pressurized dissolved air flotation of this routine is planted the same shortcoming of air supporting with the first two.
Summary of the invention
The utility model has overcome the deficiency that above-mentioned three kinds of air supportings exist, provide that a kind of volume is little, less energy consumption, treatment capacity is big, effluent quality is good flotation machine, the utility model also provide move under a kind of low pressure, can make gas all produce the small-sized gas-water mixer of particle diameter after the aerating less than the following microbubble of 5 μ m, make the air flotation technology of flotation machine reach a new height.The utility model is to implement like this: a kind of efficient induced gas floatator, comprise that two ends are provided with the horizontal cylinder of water inlet pipe and water outlet pipe, it is characterized in that successively being provided with in the cylindrical shell coagulating chamber, bubble absorption chamber, air flotation separating chamber and purification hydroecium, be separated by with vertical partition plate between each chamber that water is communicated with, place the outer gas-water mixer of reliever pipe connection cylindrical shell of bottom, bubble absorption chamber, the upper end of air flotation separating chamber is provided with the scum silica frost collection bucket.Add later river or the sewage of coagulating agent and enter the coagulating chamber of barrel front end through water inlet pipe, suspended substance becomes flco behind aggregation, slowly flow into the bubble absorption chamber that is provided with reliever then, suspended substance is adsorbed by microbubble, after entering air flotation separating chamber, the suspended substance that floats to the water surface is concentrated from the pipeline discharge by the scum silica frost collection bucket, and purifying waste water flows into the chamber of purifying waste water, and discharges from rising pipe.
In order to prevent that flinging of current from producing the vortex phenomenon, influence the floatation purification effect, the liquid level top of bubble absorption of the present utility model chamber and air flotation separating chamber is provided with T shape porous weather board.
In the dissolved air flotation process, for stationary flow and prevent to flow to the water that purifies hydroecium and take away the heavy suspended substance of minority, the utility model is horizontally disposed with one deck grid stabilier in that dissolved air flotation is indoor, and installs filtering material between plate, further purifies water.
Suspended substance in the sewage bubble absorption is indoor adhere to microbubble after, flow to air flotation separating chamber for the ease of it, the vertical partition plate upper end of the utility model between bubble absorption chamber and air flotation separating chamber is provided with a swash plate that tends to air flotation separating chamber as promoting scum silica frost mobile flow deflector.
The indoor liquid level equilibrium plate that also is provided with of purifying waste water of the present utility model, its height is once determining that the water level during operation has just remained unchanged; In addition, the bottom that purifies hydroecium also is provided with a rising pipe, and described rising pipe connects gas-water mixer through reflux pump.
Being a centre with the gas-water mixer of reliever pipe connection in the utility model is separated into the cylindrical tube of mixing section and release room with a porous plectane, and the inlet pipe of band shower nozzle stretches in mixing section through release room.The gas tip of this gas-water mixer is the cylindrical tube that a side is furnished with circular port.This gas-water mixer generally is the small-sized gas-water mixer with one section steel pipe manufacturing, it can be under low pressure, with synergic system the gas of confession through gas tip, ejecting microbubble is mixed by recirculation water, absorption becomes the dissolved air water that contains microbubble, and this small-sized gas-water mixer can make the gas of adding all become particle diameter less than the microbubble below the 5 μ m, guaranteed that the suspended substance flco in the flotation machine is farthest adsorbed by bubble, floating going up separated, improve the floatation purification rate, need not to increase the dissolved air water amount, add long residence time, just can reach the effluent quality requirement, thereby make equipment volume little, the processed in units water yield is big, and low pressure operation has reduced the operation electric load again, and production cost is low.
