Description
Technical field
The present invention relates to a kind of aerator, more particularly to the efficient aeration dress of a kind of installation and maintenance simplicity, coefficient of oxygen utilization
Put.
Background technology
Water pollution problems is an environmental problem all over the world, and sewage disposal can be divided into thing by the Method means for adopting
4 kinds of logos, chemical method, physical-chemical process and bioanalysises.Bioanalysises are to decompose dirty using the metabolism of the microorganism in waste water
A kind of method of the Organic substance of degradable in water, because having treating capacity big, reduced investment the characteristics of economic and reliable, becomes current
A kind of most common method for treating water in the world.Wherein, aerobe method faces the aspects such as aeration efficiency, the performance of aerator
Restriction.
Aeration type is broadly divided into two classes：One class is blast aeration, is drawn in water using aerator diffuser plate or anemostat
Enter the aeration mode of bubble；Adopting in this way the sewage disposal of general ethylene plant more.Another kind of is mechanical aeration, refers to and utilizes leaf
The apparatuses such as wheel introduce the aeration mode of bubble.
The form of micropore aeration pipe has a lot, and that what is more commonly used at present has two kinds：One kind is sintered by coarse porcelain or corundum etc.
Common aeration tube, this tube wall produces many atomic little holes in sintering process, it be mainly characterized by can produce
The small bubble of life, bubble diameter about 0.1mm ~ 0.2mm, air-liquid contact area is big, and coefficient of oxygen utilization is high, typically can reach 20~
25%；It has the disadvantage that atmospheric pressure lost is larger, easily blocking, and the air of feeding needs Jing filtrations to process；It is fragile, once damage, oxygen profit
Rapid decrease is begun to rate；And service life is short, it is difficult to change.
Another kind is tubular membrane micropore aeration pipe.The mounting means of this aeration tube is essentially the same with former, but its
The complex structure of itself, it is that pipe, as gas distribution pipe, is provided with air vent, cloth by made by one with ABS or UPVC on tube wall
Trachea periphery is covered with diaphragm made by synthetic rubber, and diaphragm is fixed on pipe by metal clamps.On synthetic rubber diaphragm
Equally distributed eyelet is got with methods such as laser.During aeration, air by the passage entrance diaphragm on tube wall and tube wall it
Between, in the presence of compressed air, diaphragm is heaved slightly, eyelet opens, and reaches the purpose of gas distribution diffusion.Stop supply, gas
After pressure disappears, diaphragm sheet makes eyelet close 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 because the opening diameter of this diaphragm directly influences the utilization rate of oxygen, because
This, opening diameter should be appropriate.Opening diameter is excessive, and the utilization rate of oxygen is relatively low, and opening diameter is too small, and coefficient of oxygen utilization is high, but resistance
Increase.Rubber diaphragm is easily aging, easily tear, causes aerator to damage, and higher to the pressure requirements of aeration
In view of this, it is necessary to which existing aerator is improved, to solve the above problems.
The content of the invention
It is an object of the invention to provide a kind of installation and maintenance simplicity, the efficient aerator of coefficient of oxygen utilization.
For achieving the above object, the invention provides a kind of aerator, including aeration head and external aeration tube connect
The aeration connector for connecing, the aeration head includes the first combination that main part, bottom bracket are combined with the aeration connector
Portion, side wall of the main part near first joint portion offers aerating pore, and the main part bottom offers aeration
Micropore；The aeration connector includes the company of the second joint portion combined with first joint portion and the connection of external aeration tube
Socket part；The aperture of the aerating pore is gradually reduced from the Inside To Outside of the main part.
As a further improvement on the present invention, first joint portion is one by hot-melt adhesive paste with second joint portion
Body.
As a further improvement on the present invention, sectional area of the sectional area of first joint portion less than main part.
As a further improvement on the present invention, the main part is cylindrical or tubular, and first binding site is in described
Main part top, side wall ring of the main part near first joint portion offered aerating pore around one week.
As a further improvement on the present invention, the aerating pore is uniformly distributed.
As a further improvement on the present invention, first joint portion and the second joint portion is cylindrical or tubular.
As a further improvement on the present invention, the aeration connector is in straight-tube shape or funnel-form.
As a further improvement on the present invention, in the inside border of the connecting portion is provided with and can be spirally connected with miscellaneous part
Silk.
The invention has the beneficial effects as follows：The aerator simple structure of the present invention, stable, the oxygen conveyed by external aeration tube
Gas enters the main part of aeration head through aeration connector, then enters in sewage via aerating pore, stable, aeration effect
Rate is high.The opposition produced when going out micropore by oxygen, makes aerator generation vibrations by a small margin, prevents aeration micro-
Hole plug, extends aerator service life.
