Abstract
The utility model discloses a sewerage oxygenating mixing nozzle. A streamlined flow deflector (2) is arranged on an inner circle of a cone nozzle (1), which forms a unity with the flow deflector (2). The energy recovery ratio is high and the discharge is four times as the cone nozzle. The flow deflector loses less energy and spurts well because of the buffering. The flow deflector not only guides flows, but also maintains the structural stability of the cone nozzle. The utility model is mainly applied to a craft of the traditional activated sludge process.
Description
Technical field
The utility model relates to technical field of sewage, especially relate to a kind of be applicable to the traditional active sludge treatment process use in sewage oxygenation mixing nozzle in many secondary jet mixed aeration devices.
Background technology
Utilize bioremediation to remove and in the sewage polar contaminants matter arranged, so far still be acknowledged as most economical processing mode, be widely used in technical field of sewage, wherein active sludge treatment program and various deutero-treatment process thereof, no matter be in city domestic sewage or industrial waste water treatment system, all occupy high application percentage.Present shower nozzle sprays and almost belongs to uniflux, and turbulent effect is bad, and power loss is big, and current are difficult for stable the outflow, the jet power poor effect, and the gas-to-liquid contact area is relatively low, and gas phase is low to the liquid phase transfer efficiency.
Summary of the invention
The purpose of this utility model provides a kind of transfer efficiency height, the sewage oxygenation mixing nozzle that power loss is little.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of sewage oxygenation mixing nozzle, the shower nozzle of nozzle is taper.
In described Conic nozzle, be provided with inducer.
The inwall circumference at described Conic nozzle heavy caliber end place is provided with inducer.
Described inducer and Conic nozzle form one.
The tapering of the shower nozzle of described nozzle is 40 °.
Described inducer is streamlining, and the inwall at its medial surface and Conic nozzle heavy caliber end place is close to and is connected as a single entity.
The utility model sewage oxygenation mixing nozzle increases inducer on traditional Conic nozzle basis, this inducer and nozzle are made integral body, inducer constitutes the guide face of sewage oxygenation mixing nozzle, makes the liquid stream deflection of sewage oxygenation mixing nozzle ejection, mixes turbulent effect efficiently thereby reach.The utility model sewage oxygenation mixing nozzle combines with the Venturi ejector, make the over-saturation mixed solution that ejects from ejector under the drainage of sewage oxygenation mixing nozzle, liquid around the drainage carries out secondary with mixed solution that sewage oxygenation mixing nozzle is sprayed once more to be mixed, thereby reclaimed power capacity, improved the transfer efficiency of gas phase accordingly.
The utility model has the advantages that: 1, energy recovery rate height, the flow of four times of nozzles of water conservancy diversion; 2, inducer is owing to play the buffered effect, and power loss is little, and jeting effect is good; 3, inducer not only plays guide functions, and keeps the stable effect of nozzle arrangements.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the shape assumption diagram of inducer 2 in the utility model.
Embodiment
The structure of a kind of sewage oxygenation of the utility model mixing nozzle is as shown in Figure 1 and Figure 2: the shower nozzle 1 of nozzle is taper, the inwall circumference at Conic nozzle 1 heavy caliber end place is provided with inducer 2, inducer 2 is the 6-8 sheet, and this inducer 2 forms one with Conic nozzle 1.In use the tapering of the shower nozzle of described nozzle is 40 ° and is preferred plan.Described inducer 2 is streamlining, and the inwall at its medial surface and Conic nozzle 1 heavy caliber end place is close to and is connected as a single entity.The utility model sewage oxygenation mixing nozzle increases inducer on traditional Conic nozzle basis, this inducer and nozzle are made integral body, inducer constitutes the guide face of sewage oxygenation mixing nozzle, make the liquid stream deflection of sewage oxygenation mixing nozzle ejection, thereby reach and mix turbulent effect efficiently, and inducer plays rotation cutting guide functions, makes gas-liquid mix the transfer efficiency height mutually efficiently.
