Description
Technical field
The utility model is related to field of waste water treatment, especially a kind of aeration dress easy, efficient, noise is small, low energy consumption
It sets and the wastewater treatment equipment with the aerator.
Background technology
Water pollution problems is an environmental problem all over the world, and sewage water treatment method is commonly divided into Physical, changes
4 kinds of method, physical-chemical process and bioanalysis.Bioanalysis is degradable organic in the metabolism Decomposition Wastewater using microorganism
A kind of method of object becomes the most common one kind in the world today because having the characteristics that treating capacity is big, invests small, economic and reliable
Method for treating water, however aerobe method treatment effect relatively conventional in bioanalysis suffers from the performance and effect of aerator
The restriction of rate etc..
The aeration type of current aerator is broadly divided into two classes：One kind is blast aeration, and one kind is mechanical aeration.Drum
Wind aeration is the aeration mode for introducing bubble in water using aerator diffuser plate or diffuser, the sewage disposal of general ethylene plant
Mostly use such mode.Mechanical aeration refers to that the aeration mode of bubble is introduced using instruments such as impellers.
The form of micropore aeration pipe as one of blast aeration typical case has very much, and relatively conventional at present has two
Kind：One is the common aeration tube made of the sintering such as coarse porcelain or corundum, this tube wall generates many atomic in sintering process
Small hole, it is mainly characterized by：Small bubble, bubble diameter about 0.1mm~0.2mm, air-liquid contact area can be generated
Greatly, coefficient of oxygen utilization is high, generally can reach 20~25%；The disadvantage is that：Atmospheric pressure lost is larger, easily blocks, the air of feeding need through
Filtration treatment；Fragile, coefficient of oxygen utilization begins to rapid decrease after damage, and service life is short, is not easy to replace.
Another kind is tubular membrane micropore aeration pipe, and the mounting means and former of this aeration tube are essentially the same, but its
Itself complicated, it is to use pipe made of ABS or UPVC as gas distribution pipe one, and venthole, cloth are provided on tube wall
Tracheae periphery is covered with diaphragm made of synthetic rubber, and diaphragm is fixed on by metal clamps on pipe, on synthetic rubber diaphragm
Equally distributed eyelet is got with the methods of laser.When aeration, air by venthole inlet membrane on tube wall and tube wall it
Between, under the action of compressed air, diaphragm is made to heave slightly, eyelet opens, and achievees the purpose that gas distribution is spread；Stop gas supply, gas
After pressure disappears, diaphragm itself makes eyelet be closed automatically under elastic reaction, due to the effect of hydraulic pressure, on the tangible tube wall of pressing diaphragm,
Therefore sewage will not flow backwards and block eyelet.But since the opening diameter of this diaphragm directly influences the utilization rate of oxygen,
Opening diameter should be appropriate；Opening diameter is excessive, and the utilization rate of oxygen is relatively low；Opening diameter is too small, and coefficient of oxygen utilization is high, but resistance increases
Greatly；And rubber diaphragm is easy to aging, tearing, causes aerator to damage, and higher to the pressure requirements of aeration.
In view of this, it is necessary to provide a kind of improved aerators, to solve the above technical problems.

After sweat soldering together, gas is flowed from above to below along the peripheral wall 22 for constituting the point, then by described
Bottom wall 251 is upwardly into the roof 241 of the upper shell 24, and air-flow is tangentially made into the rotation point intracavitary along peripheral wall 22 during being somebody's turn to do
At rotary motion so that solid particle and gas with larger centrifugal inertial force separate, and the air-flow of rotation is received in rotation point intracavitary
It contracts to center flow, is upwardly formed secondary vortex flow and is discharged through first micropore 211, and the solid for being thrown toward the peripheral wall 22 is miscellaneous
Matter falls on the bottom 23 of lower shell 25 under peripheral wall 22 under the effect of gravity, is discharged by the second micropore 231.During being somebody's turn to do, into
The gas for entering the rotation point intracavitary mainly rotates in the arc sections, will not cause shadow into the rotation point intracavitary to gas
It rings so that stable gas pressure, aeration are stablized.
It will be appreciated by persons skilled in the art that the aerator 100 is generally positioned at the exposure of wastewater treatment equipment
In gas pond or enhancing tube, and the diameter of the aerator 100 is less than the internal diameter of aeration tank or enhancing tube.The aeration cylinder 2
Further include the support element 26 set on 25 outside of the upper shell 24 or the lower shell, in operational process of divulging information, the aeration
When device 100 vibrates caused by wind pressure variation, air-flow recoil strength etc., by the support element 26 far from the aeration cylinder
The inner wall of one end and the aeration tank or enhancing tube offsets and makes overall stability preferable, and then is aerated and stablizes, and device
It is unlikely to deform.
The utility model also provides a kind of wastewater treatment equipment, including aeration tank or enhancing tube, is connected to the aeration tank
Or the enhancing tube aeration tube, be connected to the above-mentioned aerator 100 of the aeration tube.The aerator 100 passes through outer
Socket part 11 connect with the aeration tube and then completes the connection with external gas source, and the aeration wind or compression generated by Aeration fan is empty
Gas enters the aerator 100 by aeration tube, and the volume of the aeration cylinder 2 plays the role of voltage stabilizing, buffering and rotation point,
Aeration wind or compressed air divide chamber, the air-flow of rotation to be shunk to center flow in rotation point intracavitary along peripheral wall 22 into rotation, and upwards
It forms secondary vortex flow and is sent into 24 top 21 of the upper shell, be distributed in waste water in the form of microbubble through described first micro- stomata,
So that water flowing direction is risen from bottom to top with microbubble, and then play the role of promotion with flow gyration, is in addition produced with reasonable aperture
The microbubble gone out is dissolves uniformly in water, realizes high efficiency, the high concentration oxygenation of sewage, and because air-flow recoil strength makes aeration fill
100 generation small vibrations are set, aeration hole plug is avoided.
In conclusion the aerator 100 of the utility model, passes through the setting of top 21 first in the aeration cylinder 2
Micropore 211, and the connector 1 is connected with described be aerated on the top 21 of cylinder 2 at the position of the peripheral wall 22, makes
Gas is obtained from after the connector 1 enters the aeration cylinder 2, along rebound forms two upwards after the streaming to bottom 23 of peripheral wall 22
Secondary vortex is sent into top 21, is distributed in waste water in the form of microbubble by first micropore 211 after rotation point mixing, forms gas
Water mixes, and realizes high efficiency, the high concentration oxygenation of waste water.
