Abstract
The invention relates to the field of sewage treatment, in particular to an aeration nozzle for sewage treatment. The aeration nozzle has an annular flange-shaped pedestal, a gas-supply jet pipe and a gas-liquid mixing guide pipe, wherein the pedestal is provided with a support bracket; the gas-liquid mixture guide pipe is fixed on the support bracket; the gas-supply jet pipe is arranged in the guide pipe and the nozzle of the gas-supply jet pipe extends out of the guide pipe in the radial direction; the gas-liquid mixture guide pipe is of an inverse waist drum type and unfolds after gradually shrinking from the top to the bottom; the ratio of the lower opening to the upper opening of the guide pipe is 3:1; a gas-supply nozzle is of an annular structure made of a hollow pipe with the diameter of 25mm; and the nozzle of the gas-supply jet pipe is a gas nozzle with the diameter of 2mm and is arranged on the surface of the gas-supply jet pipe. The aeration nozzle prevents sediment from silting and settling at the bottom, increases oxygen dissolved in water, enlarges gas-liquid contact area, and quickens the dissolution of gas in the water.
Description
Technical field
The present invention relates to sewage treatment area, especially a kind of aeration nozzle for sewage treatment.
Background technology
Along with improving constantly of sewage treatment process, various WWT 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. exists all that gas loss is big, back pressure is high, be prone to disadvantages such as 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.
Summary of the invention
The technical problem that the present invention will solve is: shortcoming and deficiency in order to solve above-mentioned existence, a kind of aeration nozzle for sewage treatment is provided, and can be widely used in the aerating system of various WWTs.
The technical solution adopted for the present invention to solve the technical problems is: a kind of aeration nozzle for sewage treatment; Have annular flange-like base, air feed jet pipe and gas-liquid mixed thrust-augmenting nozzle, base is provided with bracing frame, and the gas-liquid mixed thrust-augmenting nozzle is fixed on the bracing frame; 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; 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 air feed jet pipe 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 invention has the beneficial effects as follows that aeration nozzle for sewage treatment of the present invention has prevented that from there is sediment alluvial deposition the bottom, and the dissolved oxygen content in the water is increased, and the gas-to-liquid contact area is increased, gas dissolving in whose speed improves.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a structured flowchart of the present invention.
Among the figure 1, base, 11, bracing frame, 2, the air feed jet pipe, 3, the gas-liquid mixed thrust-augmenting nozzle.
Embodiment
Combine accompanying drawing that the present invention is done further detailed explanation now.These accompanying drawings are the synoptic diagram of simplification, substruction of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
The aeration nozzle for sewage treatment 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, and 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 from bottom to top gradually and launches, and end opening and ratio suitable for reading are 3: 1, and length is decided as requested.The air feed jet pipe 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 present invention can require to adopt stainless steel or other metallic substance material according to WWT, on flange-like base 1, has fixed screw holes, and blowing angle is 60 degree, through fixed screw holes base 1 is fixed in the bottom, aeration tank.In aeration nozzle, carry air through 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 and follow the effect of the air lift that gas rises further to improve, and quicken jet, accelerated the flow velocity of the two-phase flow of gas-liquid at the thin segment of thrust-augmenting nozzle; Can in water body, form powerful and stable cycling stream; Prevented that from there is sediment alluvial deposition the bottom, is that organism is in suspended state, thereby helps 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 in gas-liquid mixed thrust-augmenting nozzle 3, to be dispersed into tiny bubble in the uphill process, so aerating apparatus can produce the spray orifice obstruction hardly.
In the present invention, the gas of rising and the air lift effect of following this ascending gas drive the sewage in the treatment system and rise, and in this process, make tiny that bubble becomes; And in moment, accomplish gas-liquid and upgrade, because the flow path of gas-liquid mixed stream shrinks gradually, through thrust-augmenting nozzle the time, obtain quickening then; When through 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, forms 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 descends the COD in the sewage, the content of BOD.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification sheets, must confirm its technical scope according to the claim scope.
