Description
Technical field
This utility model relates to sewage-treatment plant technical field, particularly relates to a kind of simple in construction, nozzle is not easily blocked, oxygenation effect good, durable in use, sewage treatment capacity is strong annular jet aerator.
Background technology
Water, is referred to as the source of human life, is most widely to exist on the earth, is again liquid the most precious.Now, the condition of this precious resources but allows of no optimist.Along with improving constantly of human living standard, constantly increasing the consumption of water, the water for whole society's service cannot escape contaminated destiny.And water is as a kind of resource the most in short supply, recycled by the mankind more and more.Along with extensively carrying out of sewage disposal, sewage disposal device have also been obtained and develops faster.
In aerobic sewage treatment process, utilize microorganism that the organic pollution in water body is decomposed, to reach the purification purpose of water quality.And the biochemical activity of microorganism is it is necessary to have oxygen source, the effect of aerator is exactly the air carried through admission line by aerator, spreads the oxygen source providing Institute of Micro-biology to need in water body.Bubble when contacting with water body by the oxygen dissolution in bubble in water.
Notification number is that the Chinese patent of CN2626991Y discloses one " rotary cutting aerator ", it includes reaction hood, air inlet pipe, use and be installed into trachea on connecting bolt, bearing is arranged in air inlet pipe, bearing is installed rotating impeller blades, support platform is arranged on bearing, installs mixing wastewater with air reactor in support platform, and reaction hood is arranged on mixing wastewater with air reactor.Its shortcoming is: during longtime running, aeration is uneven, admission line easily blocks, and aerator fluctuation of service, have impact on the operational effect of aerator.
In a word, aerator of the prior art has the drawback that: 1, nozzle design is unreasonable, and the most void designs of nozzle is too small, causes nozzle easily to block, affects wastewater treatment efficiency；2, aerator is bad to the treatment effect of sewage, disposal ability is limited, is not suitable for large-scale sewage disposal；3, the durability of aerator is poor, maintenance difficult.
Visible, sewage disposal needs the aerator a kind of being not easily blocked, coefficient of oxygen utilization is high, oxygenation effect is good, durable in use, sewage treatment capacity is strong, to meet the demand of sewage disposal.
Summary of the invention
This utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of annular jet aerator, and its simple in construction, nozzle are not easily blocked, and oxygenation effect is good, sewage treatment capacity strong, good energy-conserving effect, durable in use.
For solving problems of the prior art, the concrete technical scheme that this utility model uses is:
A kind of annular jet aerator, annular guide shell including a hollow, described guide shell is provided with all vertical with guide shell place plane air inlet and water inlet, described air inlet all connects setting with water inlet with guide shell, described air inlet and water inlet are respectively arranged at the both sides of described guide shell place plane, and described air inlet and water inlet interval angles are 180 degree；Multiple bracing frame and nozzle are distributed in the peripheral circumferential of described guide shell, and support frame as described above is evenly distributed in the peripheral circumferential of guide shell, and described nozzle is uniformly distributed in air inlet and the both sides of water inlet place plane；Described air inlet is connected with aerator, and described water inlet is connected with circulation delivery side of pump.
Preferably scheme, the quantity of support frame as described above is 4～6.
Further preferred scheme, the quantity of described nozzle is 6～12.
Further preferably scheme, described nozzle is conical nozzle, and osculum one end of its taper is outwards arranged.
Further preferred scheme, the entrance of described circulating pump is provided with filter.
By using such scheme, compared with prior art, it has the technical effect that a kind of annular jet aerator of the present utility model
1, this utility model oxygenation effect is good, it is that cause greatly because process water yield change and air is under-supply effectively to make up, and sewage treatment capacity is strong, good energy-conserving effect；
2, using jet type nozzle, nozzle is not easily blocked, and service life is long, can carry out effective deep water aeration；
3, this utility model simple in construction, durable in use, safeguard simple；
4, this utility model annular jet aerator is not necessarily mounted at the bottom of pond, and therefore selected blower pressure can reduce 1/3rd, thus can save the energy of 20% ~ 25%, more energy-conservation；
The depth of water of Aeration tank that 5, this utility model is serviced more usual 5～6 meters, can increase to 8～10 meters, such that it is able to make whole Aeration tank reduce by the floor space of 1/to three/4ths.
Accompanying drawing explanation
Fig. 1 is the front view of this utility model a kind of annular jet aerator；
Fig. 2 is the left side view of this utility model a kind of annular jet aerator；
Fig. 3 is the using method schematic diagram of this utility model a kind of annular jet aerator.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage of greater clarity, below in conjunction with instantiation and referring to the drawings, this utility model is further described.It should be understood that these describe the most exemplary, and it is not intended to limit scope of the present utility model.Additionally, in the following description, eliminate the description to known features and technology, to avoid unnecessarily obscuring concept of the present utility model.
