Description
Technical field
The utility model relates to a kind of oxygenation aerating apparatus, specifically a kind of built-up type efflux aerator.
Background technology
Aerating apparatus is the key equipment of sewage biochemical treatment, and its performance quality directly has influence on treatment effect and operation energy consumption.The deficiency that efflux aerator commonly used in use exists in the prior art is complex manufacturing technology, the cost of manufacture height, the maintain and replace inconvenience, work-ing life is short, the aerating apparatus of prior art all is that cast iron casting is made, nozzle such as disjunctor uses because of long-time, spout abrasion becomes big or stops up bore because of corrosion and diminishes, the capital has influence on the jet-flow aeration effect, only because of parts damages of nozzle, although other parts are very intact, discarded a whole set of replacing of also having to: thereby cause use cost to increase.
Summary of the invention
The purpose of this utility model is the shortcoming and defect that overcomes above two kinds of aerating apparatuss commonly used, provide a kind of easy to use, oxygen transfer rate is high, be difficult for stopping up, the built-up type efflux aerator of easy care.
The purpose of this utility model realizes in the following manner, its structure is by high-pressure intake pipe, ejector nozzle, the aeration Y-tube is formed, wherein, the left end of the right-hand member of high-pressure intake pipe and aeration Y-tube is provided with flange, the left end of ejector nozzle is provided with flange, the flange of ejector nozzle is arranged between the flange that the left end of the right-hand member of high-pressure intake pipe and aeration Y-tube arranges, the three by bolting together, the conical nozzle of ejector nozzle extends among the aeration Y-tube, the right side that is positioned at aeration Y-tube left end flange is provided with inlet pipe, the lower end of inlet pipe is positioned at the upper right side of the conical nozzle of ejector nozzle, the inlet pipe right side of aeration Y-tube is provided with a bend pipe, and the inwall of bend pipe is provided with the flow-disturbing groove.
The control of the bent angle of bend pipe is at 10-40 ° on the aeration Y-tube.
Combination high-efficiency fluidic device of the present utility model is compared outstanding beneficial effect with prior art:
(1) because the micro-bubble that produces in the flow process of gas-liquid in aeration Y-tube and aeration bend pipe has greatly improved the contact area of gas-liquid two-phase, so the oxygen transfer rate height;
(2) air capacity can flexible and do not influence biochemistry pool and mix the effect that stirs, and in addition, because the handiness that this aerating apparatus tolerance is regulated, it is particularly suitable at anoxic, good oxygen condition downward modulation joint oxygen-supplying amount to save energy consumption;
(3) be suitable for the depth of water and be generally 6-9m; Can reach 14, can save floor space in a large number;
(4) Gao Su current have a large amount of kinetic energy, can realize the purpose of directed plug-flow and stirring, to satisfy the needs of different biochemical process;
(5) wide to the blower fan suitability, need not to add air filter;
This aerating apparatus no-rotary part, can select for use different materials processing to make according to different sites, can use stainless steel part, ironcasting or engineering plastics such as the aeration Y-tube, nozzle can use the erosion-resisting alloy of high-strength, high-anti-friction, not only solved ironcasting low problem in not corrosion-resistant work-ing life, also be easy to processing, reduce production costs significantly and use cost.
Description of drawings
Fig. 1 is the structural representation of built-up type efflux aerator.
Description of reference numerals: high-pressure intake pipe 1, flange 2, ejector nozzle 3, inlet pipe 4, aeration Y-tube 5, bend pipe 6, flow-disturbing groove 7.
Embodiment
With reference to Figure of description a kind of built-up type efflux aerator of inventing type is done following detailed description.
Built-up type efflux aerator of the present utility model, its structure is by high-pressure intake pipe 1, ejector nozzle 3, aeration Y-tube 5 is formed, wherein, the left end of the right-hand member of high-pressure intake pipe 1 and aeration Y-tube 5 is provided with flange 2, the left end of ejector nozzle 3 is provided with flange 2, the flange of ejector nozzle 3 is arranged between the flange 2 that the left end of the right-hand member of high-pressure intake pipe 1 and aeration Y-tube 5 arranges, the three by bolting together, the conical nozzle of ejector nozzle 3 extends among the aeration Y-tube 5, the right side that is positioned at aeration Y-tube 5 left end flanges 2 is provided with inlet pipe 4, the lower end of inlet pipe 4 is positioned at the upper right side of the conical nozzle of ejector nozzle 3, inlet pipe 4 right sides of aeration Y-tube 5 are provided with a bend pipe 6, and the inwall of bend pipe 6 is provided with flow-disturbing groove 7.
The control of the bent angle of bend pipe is at 10-40 ° on the aeration Y-tube.
Built-up type efflux aerator of the present utility model is the negative pressure that produces below inlet pipe when utilizing ejector nozzle to spray in the aeration Y-tube, and air is sucked in the aeration Y-tube, and the air water mixed solution enters in the bend pipe and mixes then.Because in bend pipe, being provided with the flow-disturbing groove, when the air water mixed solution is flowed through herein, can produce high-speed eddy at this, blending, air is divided into countless micro-bubbles and pressurized water sprays in the lump, the micro-bubble of Chan Shenging has just improved the contact area of gas-liquid two-phase like this, has reached the purpose of highly effective oxygen dissolving.
A kind of built-up type efflux aerator of the present utility model, its processing and fabricating is very simple and convenient, gets final product with the processing of universal machine working method shown in the by specification accompanying drawing 1.Can utilize submersible pump or vertical pump to realize easily for pressurized water, can be installed in the pond and also can be installed on outside the pond, all adopt the domestic standard product.
Except the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
