Embodiment
In order better to understand the purpose of this utility model, constructional feature and function are described in detail below in conjunction with structure, working process and the function of accompanying drawing to preferred implementation of the present utility model.
Fig. 1 is that aerating system described in the utility model is placed in the view in the wastewater disposal basin, as shown in Figure 1, described aerating system includes gas blower 3, jet aerator 4, recycle pump 2 and strainer 5, and wherein jet aerator 4 has gas inlet 42 and liquid inlet 43; Described gas inlet 42 is connected in gas blower 3, comes the aerating system air feed by gas blower; Described liquid inlet 43 is connected in the outlet of recycle pump 2; The ingress of recycle pump 2 is provided with strainer 5, and avoiding when recycle pump 2 draws water in the wastewater disposal basin 1, the large volume impurity in the wastewater disposal basin 1 enters recycle pump 2, thereby the operation of recycle pump and jet aerator 4 is exerted an influence.
Further, described gas blower 3 can be Root's blower, rotary drum blower fan or multistage blowers, as long as can reach wind supply quantity.
Further, described recycle pump 2 can be selected impeller pump, and mixed, propeller pump etc. only need satisfy flow lift and get final product.
Further, Fig. 2 a, Fig. 2 b and 2c have showed a kind of front view, vertical view and left view that is applied to the straight pipe type jet aerator of above-mentioned aerating system.Shown in Fig. 2 a, described jet aerator 4 is straight tube-like, it includes sap cavity 41, air cavity 44, total nozzle 45, liquid jet 46 and gas inlet 42 and liquid inlet 43, wherein, described sap cavity 41 is a common static pressure chamber, to guarantee that liquid sprays all liquid jets 46 with identical pressure, described liquid inlet 43 is arranged on the sap cavity; Described air cavity 44 is a common static pressure chamber, can reach each total nozzle 45 to guarantee gas, and described air cavity is provided with gas inlet 42, isolates mutually between described sap cavity and the air cavity, is not communicated with each other.Evenly be provided with a plurality of total nozzle 45(on the described air cavity tube wall shown in Fig. 2 a), the position of corresponding described total nozzle on the described sap cavity tube wall, be correspondingly provided with liquid jet 46, and described liquid jet 46 offers in air cavity 44, and extend towards total nozzle 45.As Fig. 2 c and shown in Figure 3.
Further, as Fig. 2 a, 2b and shown in Figure 3, as can be known, described air cavity 44 walks abreast mutually with described sap cavity 41 and depends on each other.
Further, straight pipe type jet aerator described in the utility model, with and each parts, for example sap cavity 41, liquid jet 46, air cavity 44, total nozzle 45, liquid inlet 43, gas inlet 42 grades can be any material of erosion resistance, it is preferably glass filament reinforced plastics (being FRP) material, and this material has erosion resistance preferably, to reach the purpose of working in the waste water of band acid-basicity.
Further, described jet aerator can include many group nozzles, namely include many total nozzles 45 of group and with the many groups of liquid jets 46 that total nozzle is corresponding.
Below in conjunction with above-mentioned aerating system and the structure that is applied to the straight pipe type jet aerator in the aerating system, the aeration process of aerating system is once described: at first, straight pipe type jet aerator 4 in the aerating system and recycle pump 2 and gas blower 3 are connected, and be provided with strainer 5 in place, recycle pump liquid inlet; Then straight pipe type jet aerator 4 is positioned in the wastewater disposal basin, and gas blower 3 and recycle pump 2 are started working, and then drive total system and start working, thereby form the circulation in " waste water pond 1---recycle pump 2---jet aerator 4---waste water pond 1 "; As shown in Figure 3, when liquid is gone out the liquid jet 46 of straight pipe type jet aerator 4, owing to have certain flow rate, at first form gas-liquid mixed district 47, the air that can drive then in the jet aerator air cavity 44 enters wastewater disposal basin 1 together through total nozzle 45.As shown in Figure 4, because the inertia of current, air water mixed flow cognition is advanced a segment distance forward (according to the depth of water, can advance 5～10 meters and not wait), at the flow velocity end, because the density of bubble is less than water, can upwards float, produce a bubble rising area 10, thereby drive the turbulent flow again of water.In this twice turbulent process, G﹠W produces the friction of the degree of depth, thereby makes that oxygen is transferred in the middle of the waste water to greatest extent in the gas, thereby makes waste water keep the oxygen enrichment state.
The above only is a kind of preferred implementation of straight pipe type jet aerator described in the utility model; should be understood that; for those skilled in the relevant art; under the prerequisite that does not break away from the utility model principle; trickle modification and the improvement made also should be considered as belonging to protection domain of the present utility model.
