Description
Technical field
The present invention relates to the air jet system in aerator field, especially aerator.
Background technology
Aerator is the equipment applied to being supplied oxygen in waste water activated sludge process water treatment procedure to aeration tank, with national near
Attention to environmental protection in several years, the application of aerator is more and more extensive, the quality of aerator, not only influences biochemical wastewater treatment effect
Fruit, and directly influence Treatment stations occupation of land, investment and operating cost.
Although the air jet system admission line of presently disclosed spiral-flow aeration is located at cylinder side, but due to needing to make gas
Therefore body would generally connect the upward bend pipe in a gas outlet in air inlet upwards.It can stop in sewage treatment plant's overhaul of the equipments
Aeration, at this moment the sludge in sewage can be very easy to be deposited in the gas outlet of the bend pipe under gravity, treat sewage disposal
When plant maintenance finishes and starts aeration, the sludge accumulated in common rotational flow aeration device gas outlet can block gas outlet, cause
Aeration can not be carried out.
Common rotational flow aeration device is at work, excessive to biological cenobium impulsive force in sewage due to air jet system
Cenobium can be caused to decompose.And the hydraulic jump phenomenon after meeting gassing water outlet, can further cause bubble to spray the spray of the water surface
Spring phenomenon.Because the agitation of aeration is acutely influential on the biological cenobium in sewage very much, easily causes sludge cenobium and crush,
Influence wastewater treatment efficiency.
The content of the invention
In order to solve technical problem present in above prior art, the present invention proposes following technical scheme：
A kind of aerator air jet system, including cylinder, the cylinder body bottom is provided with liquid inlet, top goes out provided with gas-liquid mixed
Mouth, in addition to air inlet, the air inlet are located at the side of the cylinder, and admission line is fixedly connected and passed through with the cylinder
The air inlet is connected with the inner barrel, and guiding surface is provided with the air inlet or the admission line is tilted and set
Put, pass the gas through admission line into after cylinder along barrel spiral.
Further, the admission line is connected along the tangential of cylinder with the cylinder.
Further, the guiding surface is located on the cylinder or the admission line.
Further, the cylinder includes the passage through both ends, and the passage includes interconnected first passage and the
Two passages, the first passage is cylindrical type, the second channel is circular platform type, and the second channel is placed in the first passage
Top.
Further, the cylinder upper end is concentric reducer's structure.
Further, the first passage of the admission line and the cylinder is connected.
Further, some reinforcements are provided between admission line and cylinder.
Further, the aerator air jet system generally plastics or metal material.
In order to solve technical problem mentioned above, the present invention realizes following technique effect：
1st, the compressed air of certain flow passes through admission line, enters cylinder by air inlet, due to what is be provided with air inlet
In the presence of inclined-plane or the admission line are obliquely installed, gas enter cylinder after, air-flow from horizontal direction be changed into spiral to
On direction, the purpose so designed be device ventilation it is initial when to horizontal direction gas increase a upwardly direction,
Prevent the air bladder in the gas-liquid mixed stream of part from going out cylinder downwards, the gas being so passed through just all rotates in inner barrel
Rise, improve the performance of air jet system；
2nd, liquid forms gas-liquid mixture fluid, gas from the liquid-inlet inspiration air jet system below cylinder while gas is passed through
Bubble in liquid mixed flow passes through the first passage of cylinder, into cylinder second channel when, because the diameter of passage becomes
Change can produce Coanda effect so that gas-liquid mixed stream can motion adherent as far as possible, prevent the bubble in gas-liquid mixed stream from accumulating
In body centre, directly sprayed in the presence of buoyancy from the gas-liquid mixed export center of device, such design adds gas
The residence time of liquid mixed flow in a device.Gas-liquid mixed stream consumes part kinetic energy by such rotary motion, by device
Brute force attack would not be produced to the biological cenobium in sewage, effectively prevent biological cenobium in sewage and break behind gas-liquid mixed outlet
Broken decomposition, common rotational flow aeration device is overcome to biological cenobium impulsive force excessive the defects of causing cenobium to decompose in sewage.Simultaneously
The hydraulic jump phenomenon of the water surface also weakens significantly after bubble water-outlet, avoids and the fountain phenomenon that bubble finally sprays the water surface occurs；
3rd, the air inlet of air jet system of the present invention is arranged on device cylinder side, because being provided with inclined-plane at air inlet or will enter
Feed channel is obliquely installed, and without additionally setting the upward bend pipe in gas outlet again, the gravitational settling direction of sludge is downward, and sludge can be through
Cross the gas outlet position of air jet system of the present invention and bottomed be stacked into aeration tank bottom.If a little sludge falls in gas outlet
Place, as long as this small amount of sludge will be blown out by starting ventilation, so the gas outlet of air jet system of the present invention will not be by sludge blockage；
4th, air jet system of the present invention is simple in construction, and air-block structure greatly reduces, atmospheric pressure lost very little, and Aeration fan can select wind
The blower fan forced down, this just reduce further the electric energy loss of blower fan.
