Abstract
The utility model relates to a cyclone-type Venturi jet aeration nozzle which comprises a collapsible tube, a trunnion, a suction opening, a diffuser tube, a flow deflector and the like. According to processing condition, 3-10 flow deflectors are welded on the inner side of the diffuser tube and are uniformly distributed along the inner side. Pressure water (containing activated sludge and sewage) from an injection pump flows through the trunnion at a high speed and then negative pressure is formed. Air is absorbed into high speed steam through the suction opening and is violently mixed with sewage and activated sludge in the trunnion to form a solid (activated sludge)-gas (air)-liquid (sewage) three-phase homogeneous emulsion jet water course. Under the guidance of the flow deflector in the diffuser tube, the three-phase homogeneous emulsion jet water course is sprayed out in a spiral diffusion way. After being sprayed out from the diffuser tube, the homogeneous emulsion whirlingly flows forward in a turbulent water body in the aeration tank to continue the mass transfer effect so as to prolong retention period of tiny bubbles in sewage. Therefore, continuous high-efficiency aeration effect is realized. The cyclone-type Venturi jet aeration nozzle provided by the utility model is prepared from stainless steel, has a simple structure, and is convenient to use.
Description
Technical field
The utility model relates to a kind of cyclone-type venturi jet-flow aeration nozzle, belongs to technical field of sewage.
Background technology
The jet-flow aeration mode has quite widely and uses at sewage treatment area, and wherein, the use of Venturi tube jet aerator is very general.The characteristics of Venturi tube jet aerator are: simple in structure, energy consumption is low, is difficult for stopping up; Working pressure range is wide, and working depth is unrestricted; Atomizing of liquids (sewage, or the mixture of sewage and mud) just with certain flow velocity through the trunnion between collapsible tube and the anemostat time as long as forming very little pressure reduction can produce negative pressure and suck air, if be equipped with air blast, then gas, the liquid mixed effect can be higher.
But; The nozzle of Venturi tube jet aerator is when forming injection stream in the market; All adopted the plug-flow spray regime, this moment is bigger from the right water resistance of the gas-liquid injection stream interface of venturi anemostat, and the existence of this back pressure; Be unfavorable for the quick formation of venturi air entry negative pressure, also be unfavorable for fully mixing of gas and liquid.
Summary of the invention
The utility model relates to a kind of cyclone-type venturi jet-flow aeration nozzle, is intended to through existing Venturi nozzle is improved, for sewage disposal provides a kind of nozzle of jet-flow aeration more efficiently.
Cyclone-type venturi jet-flow aeration nozzle comprises collapsible tube, trunnion, air entry, anemostat, it is characterized in that also comprising that deflector, deflector are welded on the anemostat inboard.
The gas-liquid mixed effect of conventional venturi jet-flow aeration nozzle is mainly leaned on and is realized that through the rate of flow of fluid of trunnion speed is big more, and the mixed effect of gas and liquid is good more.The utility model has increased deflector in the anemostat inboard of common Venturi nozzle; 3～10 deflectors and the evenly distribution along the deflector inboard are set in the anemostat; Sewage through behind the trunnion anemostat is inner form injection stream in because the guide functions of deflector, injection stream is in the process of spraying forward rapidly; Form screw type and spray current, i.e. eddy flow.Spray current than pulling flow type; The waterpower back pressure that spiral-flow type is sprayed current is littler; Micro-bubble in the injection stream becomes helical type diffusion track in the process of advancing; The turbulent stirring action that this has just prolonged the time of contact of bubble and liquid and has strengthened micro-bubble and sewage, gas-liquid mixed thereby more abundant, aeration effect are therefore better.
The beneficial effect that a kind of cyclone-type venturi of the utility model jet-flow aeration nozzle is implemented is: improved the formed injection stream progression of conventional venturi jet-flow aeration nozzle; The aeration efficient and the coefficient of oxygen utilization of jet aerator have been improved; Make the aeration better effects if under the jet-flow aeration mode, the waterpower mixing effect is stronger.
Description of drawings
A kind of cyclone-type venturi of Fig. 1 jet-flow aeration structure of nozzle sketch map.
Fig. 2 is the left view of Fig. 1.
Wherein: 1-collapsible tube, 2-air entry, 3-trunnion, 4-anemostat, 5-deflector.
The specific embodiment
A kind of cyclone-type venturi of the utility model jet-flow aeration nozzle shown in accompanying drawing, comprising: collapsible tube 1; Air entry 2, trunnion 3, anemostat 4; Parts such as deflector 5; Wherein deflector 5 is welded on anemostat 4 inboards, can be set to 3～10 and evenly distribution (left side figure is 2 sketch mapes in the accompanying drawing, and right figure is 4 sketch mapes) according to process conditions; Begin the end (deflector 5 is a linear pattern in the accompanying drawing) of type or parabolic type spiral to anemostat 4 linearly along the inboard of anemostat 4 from trunnion 3 and anemostat 4 intersections.
The utility model is when implementing; When getting into trunnion 3 through collapsible tube 1 from the press water (containing activated sludge, sewage) of jet pump; Flow velocity is accelerated because of pipeline shrinks suddenly; Form negative pressure when high-velocity flow flows through trunnion 3, air is inhaled into high-velocity flow through air entry 2 under action of negative pressure, and (activated sludge), gas (air), liquid (sewage) three-phase emulsifying liquid spray current admittedly in trunnion 3, to mix formation with sewage, activated sludge fierceness; And from anemostat 4 under the guiding of deflector 5, become spiral diffusion type jet flow and go out.After 4 ejections of emulsifying liquid self-diffusion pipe, eddy flow advances in the water body of turbulent fluctuation in the aeration tank, continues effect of mass transmitting, has prolonged the time of staying of micro-bubble in sewage, thereby realizes sustainable high efficiency aeration effect.
The utility model adopts the manufacturings of SUS304, SUS316 or SUS316L stainless steel material, has stronger corrosion-resistant, wear-resisting, heatproof, resistance to compression and oxidation resistance.
