Description
Technical field
The utility model relates to sewage treatment area, especially a kind of aeration nozzle that is used for sewage disposal.
Background technology
Along with improving constantly of sewage treatment process, various sewage disposal equipments continue to bring out.Particularly the aerating apparatus in the treatment system is also in continuous renewal, but employed aeration plate in the aeration facility commonly used, aeration head is organic and aeration flexible pipe etc. all exists disadvantages such as gas loss is big, back pressure is high, easy obstruction.Generally be applied to full pond vertical aeration, and bubble increases gradually in the vertical uplift process, can't reach high efficiency two to combine, vertical range is shorter in addition, and most of bubble can't stop in sewage and go out the water surface fast, causes the idle waste of gas.Particularly when utilizing pipeline to do the gas-liquid two-phase mixing, do not reach the aeration effect at all.
The utility model content
The technical problems to be solved in the utility model is: shortcoming and deficiency in order to solve above-mentioned existence, a kind of aeration nozzle that is used for sewage disposal is provided, and can be widely used in the aerating system of various sewage disposals.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of aeration nozzle that is used for sewage disposal, have annular flange-like base, air feed jet pipe and gas-liquid mixed thrust-augmenting nozzle, base is provided with bracing frame, the gas-liquid mixed thrust-augmenting nozzle is fixed on the bracing frame, and the air feed jet pipe is arranged in the thrust-augmenting nozzle and the spout of air feed jet pipe extends radially out thrust-augmenting nozzle.
Further, described gas-liquid mixed thrust-augmenting nozzle is the type of falling the waist drum, shrinks the back from bottom to top gradually and launches, and end opening and ratio suitable for reading are 3: 1.
Described spray nozzle of the gas supply is that diameter is the ring structure that the 25mm open tube is made.
The spout of described air feed jet pipe is that diameter is the gas spout that 2mm is arranged on the jet pipe surface.
The beneficial effects of the utility model are, the aeration nozzle that is used for sewage disposal of the present utility model has prevented that from there is sediment alluvial precipitation the bottom, and the dissolved oxygen content in the water is increased, and the gas-to-liquid contact area is increased, and gas dissolving in whose speed improves.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structured flowchart of the present utility model.
Among the figure 1, base, 11, bracing frame, 2, the air feed jet pipe, 3, the gas-liquid mixed thrust-augmenting nozzle.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The aeration nozzle that is used for sewage disposal of preferred forms as shown in Figure 1, have annular flange-like base 1, air feed jet pipe 2 and gas-liquid mixed thrust-augmenting nozzle 3, base 1 is provided with bracing frame 11, bracing frame 11 is that four and diameter are 12mm, gas-liquid mixed thrust-augmenting nozzle 3 is fixed on the bracing frame 11, and air feed jet pipe 2 is arranged in the thrust-augmenting nozzle and the spout of air feed jet pipe 2 extends radially out thrust-augmenting nozzle.
Gas-liquid mixed thrust-augmenting nozzle 3 is the type of falling the waist drum, shrinks the back expansion from bottom to top gradually, and end opening and ratio suitable for reading are 3: 1, and length is decided as requested.Spray nozzle of the gas supply is that diameter is the ring structure that the 25mm open tube is made, and the diameter of ring is 3/4ths of gas-liquid mixed thrust-augmenting nozzle 3 lower port diameters.The spout of air feed jet pipe 2 is that diameter is the gas spout that 2mm is arranged on the jet pipe surface, and opening angle is 5 degree apart from the ring center.
The utility model can require to adopt stainless steel or other metallic substance material according to sewage disposal, has fixed screw holes on flange-like base 1, and blowing angle is 60 degree, by fixed screw holes base 1 is fixed in the bottom, aeration tank.In aeration nozzle, carry air by air feed jet pipe 2, in gas-liquid mixed thrust-augmenting nozzle 3, be dispersed into tiny bubble in the uphill process, sewage follows gas to rise rapidly along the water conservancy diversion tube wall fast when gas upwards sprays, because the bore of gas-liquid mixed thrust-augmenting nozzle 3 peristomes is to dwindle gradually launching from bottom to top, impel the effect of the air lift of following the gas rising further to improve, and quicken jet at the thin segment of thrust-augmenting nozzle, accelerated the flow velocity of the two-phase flow of gas-liquid, can in water body, form powerful and stable cycling stream, prevented that from there is sediment alluvial precipitation the bottom, be that organism is in suspended state, thereby help the abundant degraded of using microbe, and again owing in the cylinder that shrinks gradually, not having other prominences, so almost there is not the pressure-losses.Because the air bolus of annular air feed jet pipe 2 mouths of pipe ejection is to be dispersed into tiny bubble in the uphill process in gas-liquid mixed thrust-augmenting nozzle 3, so aerating apparatus can produce the spray orifice obstruction hardly.
In the utility model, the gas that rises and follow the air lift effect of this ascending gas that the sewage in the treatment system is driven and rise, in this process, make the tiny of bubble change, and in moment, finish gas-liquid and upgrade, flow path owing to gas-liquid mixed stream shrinks gradually then, by thrust-augmenting nozzle the time, obtain quickening, when by the outlet of thrust-augmenting nozzle upper end expansion portion, biphase gas and liquid flow is because the unexpected release of pressure, under the effect of liquid shear power, form powerful cycling stream with the littler of bubble breaking and in water body, therefore micro-bubble evenly is transported in the water body, with the carrying out that said process goes round and begins again, the dissolved oxygen content in the water body is increased, the gas-to-liquid contact area is increased, gas dissolving improves in the velocity sag of water, and its result makes the COD in the sewage, the content of BOD descends.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification sheets, must determine its technical scope according to the claim scope.
