Abstract
The invention discloses an air diffusion aerator. The air diffusion aerator comprises an air inlet pipe and an inverted umbrella cap, wherein the upper end of the air inlet pipe is connected with the lower end of the inverted umbrella cap through a perforated pipe; four walls of the perforated pipe are provided with a plurality of micro-pores passing through the pipe wall of the perforated pipe; the pipe wall of the perforated pipe on which the micro-pores are formed is provided with extension conduits with the same or different extension lengths; and at least two layers of conical teeth are distributed on the outside cap wall of the inverted umbrella cap. Since the technical scheme is adopted, air current enters a medium from the micro-pores of the perforated pipe after entering the perforated pipe. The air diffusion aerator has the advantages of simple structure, fine air bubbles entering the medium, uniform distribution and high oxygen mass transfer efficiency.
Description
Technical field
The present invention relates to a kind of air diffusion aerator.
Background technology
Aeration is meant and passes through suitable equipment artificially that bubbling air in biochemical aeration tank is to reach its intended purposes.Aeration not only makes liquid-to-air contact oxygenation in the pond, and owing to agitated liquid, has quickened the transfer of oxygen in liquid in the air, thereby finished the purpose of oxygenation; In addition, aeration prevents that in addition pond inner suspension body from sinking, and strengthens the purpose that organism contacts with microorganism and dissolved oxygen in the pond.Thereby in the assurance pond there be under the condition of sufficient dissolved oxygen microorganism, to organic oxygenolysis in the sewage.In sewage aerobic biochemical processing methods such as activated sludge process, biomembrance process and contact oxidation method, aeration aerating all is indispensable important component part.
The domestic aerating apparatus of some manufacturer production at present mainly contains: micro-hole aerator, air diffusion aerator, perforated pipe and aeration flexible pipe etc., but have following shortcoming behind these aerated product life-time service: aeration is inhomogeneous more, the liquid stirring effect reduces, solarization air cap easily stops up, it is big that bubble becomes, and the mass transfer effect of oxygen is poor.As China national Department of Intellectual Property on March 30th, 2005 the disclosed patent No. be 200420049933.1, name is called the utility model patent of efficient micro porous aeration head, its aeration effect is just waited to improve.In order to overcome these shortcomings, some improved products have appearred in aerating apparatus, but complex structure costs an arm and a leg, and also can occur behind the life-time service stopping up the unequal phenomenon of aeration.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of simple in structure, cheap, uniform air diffusion aerator of aeration, make aeration head behind the life-time service phenomenon with the aeration inequality not occur stopping up, guarantee the aerobic demand of microorganism and the stirring effect of liquid.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of air diffusion aerator, comprise inlet pipe and the cover of falling the umbrella, it is characterized in that: described inlet pipe upper end links to each other with the cover of falling umbrella lower end by a perforated pipe, and described perforated pipe wall is provided with the micropore that several run through the perforated pipe tube wall.
As preferably, described perforated pipe is cylindrical, and the tube wall of described perforated pipe is provided with two-layer at least micropore.The tube wall of described perforated pipe is provided with three layers of micropore, and every layer of micropore is provided with 4～8 micropores and uniform distribution on the tube wall circumference of perforated pipe.
Improved, the perforated pipe tube wall at described micropore place is provided with the identical or different extension conduit of development length.Bubble is evenly distributed, improves the aeration effect.
As preferably, two-layer at least conical insert is distributing on the described cover of falling the umbrella outside mask wall.The conical insert of the cover of falling umbrella cutting bubble, thereby the size of having disperseed bubble have improved the coefficient that reaches of the utilization ratio of oxygen in the air and oxygen.
The present invention enters medium owing to after having adopted technique scheme, air-flow to enter perforated pipe from the micropore of perforated pipe, simple in structure, and makes the bubble that enters medium tiny, is evenly distributed oxygen transfer efficient height.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is further described:
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, be the embodiment of a kind of air diffusion aerator of the present invention, comprise inlet pipe 3 and the cover of falling the umbrella 1, described inlet pipe 3 upper ends link to each other with the cover of falling the umbrella 1 lower end by a perforated pipe 2, and described perforated pipe 2 walls are provided with several micropores that runs through the perforated pipe tube wall 4.Described perforated pipe is cylindrical.The tube wall of described perforated pipe is provided with three layers of micropore 4, and every layer of micropore is provided with 4～8 micropores and uniform distribution on the tube wall circumference of perforated pipe.The perforated pipe tube wall at described micropore place is provided with the identical or different extension conduit 41 of development length, extends catheter length in the present embodiment from top to bottom and rises progressively gradually.Two-layer at least conical insert 5 is distributing on the described cover of the falling the umbrella 1 outside mask wall.
Principle of work of the present invention is as follows: air communication is crossed inlet pipe and is entered perforated pipe, and enters medium from the micropore of perforated pipe.The a large amount of bubbles that enter medium are at the buoyancy function float downward, cut by the conical insert of the cover of falling the umbrella, thereby the size of having disperseed bubble have improved the coefficient that reaches of the utilization ratio of oxygen in the air and oxygen.This technology is compared with product in the past, have simple in structure, long service life, bubble is tiny, is evenly distributed oxygen transfer efficient height, low cost and other advantages.
