The rotational flow mixing diffusion aerator fully utilizes the fluid dynamic energy to generate rotational flow mixing action to make the contact surface of air and fluid spread rapidly, so that the efficiency of aeration and oxygenation can be enhanced.
Description
The utility model relates to a kind of aerating apparatus of the usefulness of disposing of sewage, and more particularly, the utility model relates to the eddy flow mixing diffusion aerator that a kind of sewage biochemical treatment is used.
Traditional aeration in sewage treatment device is a micro-hole aerator, this aerator adopts the micropore exhaust mode, oxygen or air are diffused in the pending water from micropore, but the aeration head of this aerating apparatus stops up easily, need often to change, and aeration resistance is big, energy consumption height, the cost for wastewater treatment of Zeng Jiaing greatly.Particularly in the long-time running process, owing to be subjected to space obstruction or the influence of pore membrane aged, oxygen-transfer efficiency can reduce greatly.In addition,, also need dust removal process is carried out in air inlet, further increased working cost because aeration head is a microvoid structure.
The purpose of this utility model is just in order to address the above problem, and a kind of aeration aerating that carries out expeditiously is provided, and the aerating apparatus resistance is little, is difficult for stopping up, the eddy flow mixing diffusion aerator of aeration stable and reliable operation.
The purpose of wood utility model is achieved in that eddy flow mixing diffusion aerator by inlet mouth, transition air chamber, eddy flow mixture generator, and up-flow stops the diffusion shell composition.Wherein inlet mouth links to each other with gas blower.The top of inlet mouth connects a columnar transition air chamber.The top of transition air chamber is socketed with an eddy flow mixture generator, this eddy flow mixture generator under the cyclonic action of two different directions, form one moment local reaction gas-liquid rotational flow strengthening district.
Wherein the eddy flow mixture generator is made up of interface, stifle, conrotatory air outlet, blade, outer back-up ring, contrary back-out gas port and cylindrical central sleeve.Cylindrical central sleeve links to each other with the transition air chamber, have long and narrow conrotatory air outlet and the contrary gas port that screws out on its top and bottom, the top of cylindrical central sleeve is connected with one and is used for stopping the interface that diffusion shell 3 links to each other with up-flow, at the top of cylindrical central sleeve a stifle is housed also.Be equipped with blade on the excircle of cylindrical central sleeve, back-up ring outside the longitudinal end of blade is connecting links together outer back-up ring and cylindrical central sleeve by blade.
The upper interface of eddy flow mixture generator stops that with up-flow diffusion shell is sleeved on.Up-flow stops that diffusion shell is turbination, and the diameter at its top is greater than the diameter of eddy flow mixture generator.Obconic diffuser plate is arranged on the eddy flow mixture generator with one heart, evenly is provided with pawl on the outer circumference surface of diffuser plate.
This eddy flow mixing diffusion aerator makes fluid along the different directions rotational flow, when meeting when flowing, can produce fierce shearing collision, mixes thereby cause fluid to obtain the turbulent fluctuation shape in moment.In the biochemical treatment process of sewage, fluid is processed water and oxygen-containing gas, and air-flow mixes through the eddy flow of aerator, produces a series of collision, shears and cuts apart, and guarantees that the tiny bubble that aerator produces is evenly distributed in the sewage.
The eddy flow mixing effect that eddy flow mixing diffusion aerator of the present utility model produces by making full use of fluid dynamic energy can make the gas-to-liquid contact face expand rapidly, thereby can greatly improve aeration aerating efficient.What exhaust and water conservancy diversion adopted all is the macropore parts, mixes producer and revolves the acting in conjunction that mixes tube with revolving, and air-flow is cut apart and spread, and is a kind of aerator that aeration and diffused junction are integrated.
By a large amount of tiny bubbles that the eddy flow mixing effect is produced, when flowing through the turbination diffuser plate, the acting in conjunction through diffuser plate and pawl has formed a large amount of tiny bubbles, floats equably then.
The advantage of eddy flow mixing diffusion aerator of the present utility model is as follows:
1, owing to do not have microvoid structure in a whole set of aerator, so resistance is little, energy consumption is low.
2, this device can keep the tiny bubble uniform distribution for a long time from having solved obstruction and vapour lock loss problem in essence, thus steady running, the trouble and worry that does not exist oxygen-transfer efficiency to reduce gradually.
3, aerating apparatus is not subjected to the influence of gas supply flow, and air demand can be regulated and control in very wide scope, and it is stable that free air delivery all can keep.
4, owing to having eliminated blockage problem, so this aerator can be exempted ordinary maintenances such as cleaning, replacing.
5, aerator all adopts high-quality corrosion resistant engineering plastics to make, and has guaranteed that the aerating apparatus long-term safety stably moves, and need not maintenance.
