Description
Technical field
The present invention relates to a kind of gas be imported to the aerator in liquid, particularly a kind of movable aerator promoting.Relate generally to a kind of aerator that utilizes gas sewage to be processed or utilized liquid to process waste gas in field of Environment Protection.
Background technology
In the waste water and exhaust treatment system of field of Environment Protection, the mixing of liquids and gases is common measures.For example: the coal-fired flue-gas of smoke stack emission is imported in alkaline absorption solution, utilize akaline liquid to absorb the sulfur dioxide after-purification discharge in coal-fired flue-gas; The sewage effluent of factory is carried out to forced aeration, airborne oxygen is imported in sewage, supplement dissolved oxygen needing in sewage purification process etc.
The most common aerator is to make tubulose or showerhead with rigid material, in the even cloth of its working face hole, by these intensive apertures, gas uniform is distributed in liquid, to reach to the object that imports gas in liquid.But on rigid material, aperture, cloth hole is relatively large, and percent opening is also lower, and the bubble producing in aeration process is larger, and negligible amounts.Such operation kinetic energy consumption is very large, and efficiency is but not high.And these through holes are as easy as rolling off a log blocked, when particularly aeration stops, liquid enters in aeration element by through hole is reverse, liquid with solid formation or crystal can stop up gradually through hole.
For improving the efficiency of aerator, people have further developed the aerator with micro-pore aeration film pipe, its aeration element is to have certain flexible flexible material (such as flexible TPU, rubber tube) on, be evenly arranged high density micropore, by these micropores, carry out aeration, when the pressure of flexible aeration film pipe inside is during lower than outside liquid pressure, the micropore of aeration film pipe is sealing state, and the path that liquid countercurrent enters aeration film pipe closes disconnected; While pressing super filmed passing tube outside liquid pressure in aeration film pipe, the base material deformation of flexibility is micropore to open state, and gas enters liquid aeration by micropore smoothly.When there is solid-phase material shutoff this flexibility aeration film pipe outside, can add the internal pressure of aeration film pipe moment.The volume of flexible aeration film pipe is increased, destroy the shape of outside plug, and by the long-pending thing that falls around the airflow scouring micropore pressurizeing and micropore.No matter the aerator that it is relatively made into by rigid material, be that aeration efficiency or anti-clogging ability all have significantly raising, and this technology and goods are fully promoted the use of at wide spectrum.
The aerator of the flexible aeration film pipe of current known use is to establish rigid frame at aeration tank underframe, at the bottom of frame space certain distance is fixed on aeration tank.At the bottom of aeration flexible pipe is layed in aeration tank through framework, connect the admission line at two ends, as Chinese patent, CN200820108556.2 is described.The aerator of this spline structure makes the rising buoyancy of aeration film pipe in water body after inflation be limited by the rigid frame above aeration film pipe, rigid frame is arranged at aeration film length of tube direction interval, so aeration film pipe also presents the heaving of the sea shape of same intervals distance when aeration state.The aeration effect of non-standard state is very inhomogeneous like this, and the performance of aeration film pipe is also not fully utilized.The gas of aeration film pipe the inside also presents turbulence-like, the drawback that has not only strengthened energy consumption but also brought aeration film pipe to rock in framework simultaneously.
Summary of the invention
Be provides a kind of aerator that liquid is carried out to stability and high efficiency aeration for overcoming the deficiencies in the prior art order of the present invention---the movable aerator that can promote.The aeration film pipe, cutting ferrule and the guiding deck that comprise the distribution high density micropore of being made by flexible material.In guiding deck the inside, be distributed with draw-in groove, counterweight chamber and gas-liquid conversion chamber.
As setting of the present invention, in guiding deck the inside, be distributed with draw-in groove, counterweight chamber and gas-liquid conversion chamber.
As setting of the present invention, cutting ferrule is positioned at the inside of aeration film pipe, cutting ferrule be close to the inner tubal wall of aeration film pipe and together with the guiding deck direction that postponing penetrate, the parallel guiding draw-in groove the inside that runs in the guide guiding deck.By cutting ferrule, the integrant movable aerator promoting of weight material of aeration film pipe and guiding deck and counterweight chamber the inside.
As the further setting of the present invention, on the top of guiding deck, be provided with guiding draw-in groove, the spacing distance that be recessed at aeration film pipe exit of guiding draw-in groove on guiding deck is less than the spacing distance of settling cutting ferrule place fluting on guiding deck.
As the further setting of the present invention, in guiding deck inside, there are two the counterweight chamber holdout device balances in left and right.
As the further setting of the present invention, gas-liquid conversion chamber respectively has more than pipeline is connected to liquid level at the two ends of aeration tank.
As the further setting of the present invention, gas-liquid conversion chamber is to work by fill water holdout device balance at the pipeline at two ends, aeration tank.
As the further setting of the present invention, gas-liquid conversion chamber is by inflating at the pipeline that is positioned at one end, aeration tank, and goes out from being positioned at the row of conduits of the aeration tank other end buoyancy that the original water in gas-liquid conversion chamber the inside carrys out modifier.
As of the present invention, further arrange, the aeration film pipe of aerator is flexible material (as TPU, rubber), and aeration film pipe is 1:30 ~ 1:5 at the girth of guiding draw-in groove the inside and the overall circumference ratio of aeration film pipe, is preferably 1:20 ~ 1:10.
The present invention is different from prior art, and device makes the weight material of aeration film pipe and guiding deck and counterweight chamber the inside form an integral body by cutting ferrule.Because the rising buoyancy equilibrium of aeration film pipe in liquid is limited by the guiding deck after counterweight, aeration film pipe can off-straight and rock in when operation, the horizontal aeration performance that provides uniformly that can be in line, and the operation of aeration gas in film pipe is also more stable.When needing repairing, device is discharged the buoyancy of water modifier by the gas-liquid conversion chamber inflation to guiding deck inside, by auxiliary lifting apparatus, can overall increase to easily the water surface, therefore have advantages of that aeration efficiency is high, energy consumption is low, it is simple, easy to maintenance to install.
Below in conjunction with drawings and Examples, the present invention is described in further detail.
