Abstract
The invention discloses a vertical-type air-flotation device, and relates to improvement on the structure of the vertical-type air-flotation device. The vertical-type air-flotation device comprises a tank body, a dissolved air releasing system and a steady flow cylinder, wherein the steady flow cylinder is arranged in the tank body; a sewage inlet pipe is arranged at the top of the tank body; a water outlet pipe is arranged on a tank wall of the middle-lower part of the tank body; the dissolved air releasing system is arranged at the bottom of the steady flow cylinder; the water inlet pipe stretches into the steady flow cylinder and corresponds to the dissolved air releasing system; the steady flow cylinder is provided with bell-mouthed upper and lower openings; and the water inlet pipe is provided with a bell-mouthed outlet. The vertical-type air-flotation device has three bell mouths, during working, water flowing from the bell-mouthed outlet of the water inlet pipe diffuses in the big bell-mouthed lower opening of the steady flow cylinder; a dissolved air releasing device ejects high-pressure air flow towards the sewage which flows and diffuses from top to bottom so as to enable the sewage to form air bubble and fast diffuse to the lower bell-mouthed opening; emulsified oil, oil particles, floccule and bigger impurities in the sewage are attached to the surface of the air bubble; and then the emulsified oil, oil particles, floccule and bigger impurities float upwards in the steady flow cylinder to the upper bell-mouthed opening of the steady flow cylinder to be removed by a skimming device.
Description
Technical field
The present invention relates to the improvement of vertical air-floating apparatus structure.
Background technology
The air supporting method is also claimed flotation process; Its principle is to manage to make a large amount of microbubble of generation in the water; To form water, gas and to be removed the three-phase mixtinite of material, under the acting in conjunction of multiple power such as IT, bubble rising buoyancy and hydrostaticpressure difference, promote micro bubble to stick on the tiny dirts such as tiny oil droplets in the sewage, SS; Because of adherend density less than floating to the water surface on the water, thereby make the separated removal of tiny dirt in the water.The common conduct of air supporting method is to the additional processing after the oily(waste)water oil removal.
The air supporting method can be divided into gas distribution air supporting method, electric floating method, biology and chemical air supporting method, dissolved air flotation.Wherein, gas distribution air supporting method (dispersion air air supporting method) is mainly utilized the mechanical shear cutting knife, and the air that is mixed in the water is ground into tiny bubble.The for example air-breathing air supporting of water pump suction pipe, jet air float, air supporting of diffuser plate aeration and turbine air flotation etc. all belong to this type of.In addition, dissolved air flotation (dissolved air air supporting method) is under certain pressure, to make air dissolves in the water and the state that reaches capacity, and then reaches the air supporting effect.
Along with the water treatment environmental protection industry (epi) develops fast; Answer the environmental protection demand now; In sewage treatment area, occurred the vertical-flow air flotation system at present, this system has successfully used aforementioned two kinds of physical treatment principles to design, and has compiled cohesion, air supporting, skimming, deposition, suction mud in one; Be a kind of water purification equipment preferably, be widely used in the industrial sewage treatment system (as: papermaking, food, plating, process hides, knitting, printing and dyeing, wool spinning, butcher, oil, chemical industry etc.).Yet present vertical-flow air flotation scrubbing rate only has about 70%, and treatment rate is not high, and self clears up with maintenance inconvenient.We discover, causing the low major cause of above-mentioned scrubbing rate is that the bubble size that forms in the device is inhomogeneous, and bigger than normal, cause elaioleucite in bubble and the sewage, throw out, the mutual adhesive rate of macromole impurity lower; Dissolved air water and former aqueous fusion are closed unconcentrated insufficient; Water outlet is mixed with untreated former water.
Summary of the invention
The present invention is directed to above-mentioned deficiency of the prior art, provide a kind of processing efficiency high vertical-type air-flotation device.
Technical scheme of the present invention is: comprise tank body, dissolve the gas release system and be arranged on a jar intravital stabilizing feed well; Said tank body top is provided with sewage water inlet pipe; The tank skin of tank body middle and lower part is provided with rising pipe, and said molten gas release system is located at said stabilizing feed well bottom, and it is interior and corresponding with said molten gas release system that said water inlet pipe stretches into stabilizing feed well; Suitable for reading and the end opening of said stabilizing feed well is respectively bell mouth shape, and the outlet of said water inlet pipe is a bell mouth shape.
The hydraucone bore of said stabilizing feed well end opening is greater than its hydraucone bore suitable for reading.
Said stabilizing feed well stack shell axially is being hyperbola.
Be provided with a circle rib in the said stabilizing feed well, said rib position is higher than the outlet of said water inlet pipe.
Be provided with back-purge system in the said stabilizing feed well, said back-purge system is positioned at said stabilizing feed well bottom.
Said tank body external wall of upper portion is provided with the clear water storehouse of a circle, and said rising pipe links to each other with said clear water storehouse, and the clear water storehouse is provided with water outlet, and water outlet static state is overflowed.
Have three hydraucones in the device of the present invention, upper and lower mouthful of difference flare of stabilizing feed well, water inlet pipe exports also flare.During work; The water inlet pipe loudspeaker export effusive water and in the typhon mouth of stabilizing feed well end opening, spread; Simultaneously, dissolve gas tripping gear (aerating apparatus), make sewage form bubble facing to the sewage ejection high pressure draft that flows out diffusion from top to bottom; And be diffused into down rapidly in the hydraucone (hydraucone of stabilizing feed well end opening), the oil in water emulsion in the sewage, elaioleucite, throw out and big impurity are attached to bubble surface; Immediately in stabilizing feed well on float, to the last hydraucone of stabilizing feed well, dispose by skimmer device.The aerating apparatus that is positioned at water inlet pipe outlet bottom is laid ringwise.For further making bubble even; Stabilizing feed well of the present invention middle part is provided with a circle rib; If the bubble that rises is more, contain more large-size bubbles, can be intercepted by this rib, intercepted the bubble roof pressure that bubble while of piling up floated by the bottom; Make mutual extrusion between the bubble at this reducing position, be broken for the more bubble of small particle size, thereby improve treatment effect.Regularly open the gas back-purge system, carry out air supporting self cleaning, maintaining.The rising pipe that said tank skin middle and lower part is provided with is connected to the conduit that stretches to top in the tank skin outside, be communicated with the clear water storehouse on top, and the water outlet on the clear water storehouse overflows water outlet static state, make overflow no longer be mixed with untreated former water and impurity.
