Abstract
The utility model discloses a variable micropore tubular aerator including support tube connected to an air manifold tube through connecting piece, a plurality of gas distribution grooves on outer surface along support tube direction, wherein said distribution grooves are connected to the air manifold tube through tube cavity of the support tube, a membrane cover made of elastic material on out surface of the support tube, wherein a plurality of self-closed micropore are opened on said membrane cover. The utility model is characterized by that when aeration, the air manifold tube and the tube cavity of the support tube inter said gas distribution grooves, the micropore on membrane cover made of elastic material splays by gas pressure and generates a plurality of fine and even bladders sending oxide into water, then area of interface promotes greatly, utilization ratio of oxide is as high as above 40% and oxygen power efficiency is as high as 9.6kgO [2]/kWh. the membrane coverer having high elastic ability is capable of being made thin thereby loss of gas pressure is lower, also power consumption and running cost are lower. At the same time the utility model has simple structure and convenience fixation and disassembly.
Description
Technical field
The utility model relates to the sewage biochemical processing device, especially relates to variable micropore tube aerator.
Background technology
Along with the continuous development of environmental protection cause, more and more higher to sewage disposal technology and processing requirement.At present the aerobic biochemical treatment process is adopted in the processing of municipal wastewater and trade effluent more, promptly in sewage, feed dissolved oxygen sewage is handled, thereby blast aeration equipment arises at the historic moment.At present the used aerator that makes has the brush of commentaries on classics, plate-spinning aerator, plate-type aerator etc., and the existing deficiency of above-mentioned aerator shows that mainly coefficient of oxygen utilization and power efficiency of oxygen supply are lower, complex structure and make, the working cost height.
The utility model content
The utility model purpose is to provide a kind of coefficient of oxygen utilization height, variable micropore tube aerator simple in structure.
For achieving the above object, the utility model can be taked following technical proposals:
Described variable micropore tube aerator comprises the supporting tube that is connected with gas distribution pipe by web member, axially is opened in the gas distribution groove of its outside surface along supporting tube, and described gas distribution groove is connected with gas distribution pipe by the tube chamber of supporting tube; Be set with the Membrane cover of making by resilient material at the supporting tube outside surface, on described Membrane cover, offer a plurality of self-closing micropores.
Be provided with the pipe collar that is used for fixing described Membrane cover at the two ends of described supporting tube.
Advantage of the present utility model is axially to be opened in along supporting tube the gas distribution groove that is connected with gas distribution pipe of its outside surface, with the Membrane cover of making by resilient material that is sleeved on the supporting tube outside surface, and be opened in fine and closely woven self-closing micropores a large amount of on the described Membrane cover.During aeration, gas enters described gas distribution groove from air manifold tube, supporting tube inner chamber, under the gaseous tension effect, micropore on the Membrane cover of being made by resilient material opens, produce a large amount of fine and closely woven uniform bubble oxygenations in water, the gas-to-liquid contact area is increased greatly, and oxygen utilization rate is up to more than 40%, and power efficiency of oxygen supply is up to 9.6kgO
2/ kWh.And when stopping air feed, the Membrane cover lock ring is on supporting tube, and the micropore on the Membrane cover is self-closing simultaneously, plays automatically anti-adverse current effect.Because Membrane cover has snappiness, and thickness can be done thinner, so the gaseous tension loss is little, energy consumption is little, working cost is low.The utility model is simple in structure simultaneously, installation, convenient disassembly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, variable micropore tube aerator described in the utility model, it comprises the supporting tube 3 that is connected with gas distribution pipe 2 by transom 1, axially be opened in the gas distribution groove 4 of its outside surface along described supporting tube 3, described gas distribution groove 4 is connected with gas distribution pipe 2 by the tube chamber 5 of supporting tube 3; Be set with the Membrane cover of making by resilient material 6 at supporting tube 3 outside surfaces, on described Membrane cover 6, offer a plurality of self-closing micropores.Be provided with the pipe collar 7 that is used for fixing Membrane cover 6 at the two ends of supporting tube 3.
Claims (2)
1, a kind of variable micropore tube aerator, it is characterized in that: it comprises the supporting tube (3) that is connected with gas distribution pipe (2) by transom (1), axially be opened in the gas distribution groove (4) of its outside surface along described supporting tube (3), described gas distribution groove (4) is connected with gas distribution pipe (2) by the tube chamber (5) of supporting tube (3); Be set with the Membrane cover of making by resilient material (6) at supporting tube (3) outside surface, on described Membrane cover (6), offer a plurality of self-closing micropores.
