Abstract
The utility model relates to a microporous aerator for all directional air distribution. The utility model is composed of an air distributing head which is formed by the integral connection of a micropore air permeable drum convex arc-shaped curved face shell plate, and an assembly connecting rod which is connected with the air distributing head in a sealing mode and is provided with a ventilating hole channel and a connecting structure, wherein, the inner part of the air distributing head is a sealed hollow cavity, and the sealed hollow cavity in the air distributing head is communicated with the outside through the ventilating hole channel of the assembly connecting rod. The utility model is characterized in that when the aerator is used for aeration, the air distributing head of the aerator carries out all directional air distribution of the upward direction, the downward direction, and the circumference. The utility model has the advantages of high oxygenizing efficiency, low power consumption, and stable running of aerating oxygenation.
Description
The utility model relates to the oxygen supply distribution device that a kind of biological treatment of sewage is used.
The aerator of treatment unit is the most key parts in sewage biological treatment technique at present, and its quality directly affects wastewater treatment efficiency and the height of device working cost and the job run efficient of device of device.Effect comparatively it is desirable to the micro-hole aerator that adopts the micro-porous permeable material to make, the actual bell jar type that mainly contains and two kinds of structural shapes of dome-type that use in the aerator of the existing actual various types that uses.Inflation good dispersity during the micropore aerator aeration oxygen supply, gas, liquid mix contact well, oxygen supply effect height.But the aeration gas flow direction is single, and to being same direction, the aerator back side and all sides do not have aeration gas flow greatly, thereby the further raising of the efficiency of oxygen supply of aerator is restricted.Bell jar type micro-hole aerator particularly, its aeration bell jar is the case structure of flat plate wall, long-time aeration uses gas distribution face sedimentary clay shape thing and the outgassing micropore of gas distribution face stopped up the aerator drag losses is strengthened gradually, energy consumption raises, aeration oxygen supply effect descends, even causes the sewage disposal operation normally not carry out.
The purpose of this utility model provide a kind of comprehensive in water gas distribution, aeration aerating efficient height, be difficult for when aeration uses taking place to stop up, the biological treatment of sewage that drag losses is little, power consumption is low is with the micro-hole aerator of comprehensive gas distribution.
The micro-hole aerator of comprehensive gas distribution is made of with the assembling union lever that has vent channel and syndeton that is sealedly connected on the air distribution head the interior air distribution head for enclosed cavity that micro-porous permeable drum convex curved shell plate integral body is formed by connecting, and air distribution head inner sealing cavity is in communication with the outside by assembling union lever vent channel.
To go out entraining air stream even at air distribution head gas distribution face each position when aerator aeration is used, further improving of the micro-hole aerator of comprehensive gas distribution is, the sealing of assembling union lever vent channel one end, be positioned on the peripheral wall surfaces of assembling union lever bar section of air distribution head enclosed cavity and be evenly equipped with production well, the air distribution head enclosed cavity is in communication with the outside by production well, assembling union lever vent channel.
Air distribution head reached the comprehensive gas distribution of all sides up and down when the micropore aerator aeration of the comprehensive gas distribution that the utility model provides used, gas distribution is more even, gas, liquid contact area have further been improved, thereby improved the efficiency of oxygen supply of aerator, quickened the biological treatment process of sewage, shorten the processing operation cycle, improved the equipment work efficient of treatment unit.Air distribution head gas distribution face is slick and sly bulging convex surface, is difficult for sedimentary clay shape thing, thereby is difficult for blockage phenomenon, so the aeration job run is stable.Accompanying drawing is an embodiment of the present utility model, and the utility model is not limited only to embodiment, further specifies the utility model below in conjunction with embodiment.
Fig. 1 is the micro-hole aerator structure iron of comprehensive gas distribution.
Fig. 2 is the assembly structure figure of the micropore aerator aeration of comprehensive gas distribution when using.
As shown in the figure, the ventilation property coverboard (2) with micropore, (3) integral body that the micro-hole aerator of comprehensive gas distribution is made by upper and lower two blocks of corundum be formed by connecting in have enclosed cavity air distribution head and in have the threaded stud type assembling union lever (4) of vent channel (8) to constitute, the upper and lower coverboard plate of air distribution head face is drum dome slip circle shape curved surface.Have the assembling union lever on the upper and lower coverboard jack is installed, threaded stud type assembling union lever inserts in the open holes, being locked by pad (6), (10), nut (11) with assembling union lever backstop mother made in one piece (5) is connected on the air distribution head, and air distribution head and assembling union lever interface are by gasket (7), (9) sealing.Vent channel one end sealing in the assembling union lever, the peripheral wall surfaces that is positioned at air distribution head enclosed cavity bar section is evenly equipped with production well (1).Aerator was located by the air outlet (12) that the assembling union lever is fastened on gas-distribution pipe (13) when aeration used, and air enters gas-distribution pipe by pipeline and then by aerator gas distribution oxygenation in water.
Be the micro-hole aerator and the existing domeshape micro-hole aerator that uses and the measured result of bell shape micropore aerator aeration oxygenation simultaneous test of comprehensive gas distribution below:
Test conditions: deoxidation clear water, initial dissolved oxygen concentration C
0=0, 4 meters of the depth of waters, air demand 2m
3/ h, service area 0.5m
2/.
(2) experiment measured result:
The test measured result proves: under equal conditions the micro-hole aerator of the comprehensive gas distribution that provides of the utility model has improved 16.56% and 26.67% respectively than existing domeshape, bell shape micro-hole aerator oxygenation capacity, theoretical dynamic efficiency has improved 17.83% and 21.47% respectively, and these two indexs are weighed the leading indicator of aerator quality just.
Claims (2)
1, a kind of micro-hole aerator of comprehensive gas distribution, it is characterized in that being made of with the assembling union lever that has vent channel and syndeton that is sealedly connected on the air distribution head the interior air distribution head for enclosed cavity that micro-porous permeable drum convex curved shell plate integral body is formed by connecting, air distribution head inner sealing cavity is in communication with the outside by assembling union lever vent channel.
2, press the micro-hole aerator of the described comprehensive gas distribution of claim 1, it is characterized in that the vent channel one end sealing of said assembling union lever, be positioned on the peripheral wall surfaces of assembling union lever bar section of air distribution head enclosed cavity and be evenly equipped with production well, the air distribution head enclosed cavity is in communication with the outside by production well, assembling union lever vent channel.
