Description
Technical field
The present invention relates to a kind of oxygen enhancing aeration device, specifically a kind of Combined jet aerating apparatus.
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 in prior art, efflux aerator commonly used in use exists is complex manufacturing technology, cost of manufacture is high, maintain and replace is inconvenient, work-ing life is short, the aerating apparatus of prior art is all that cast iron casting is made, such as the nozzle of disjunctor uses because of long-time, spout abrasion becomes large 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 objective of the invention is to overcome the shortcoming and defect of 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 Combined jet aerating apparatus of easy care.
the objective of the invention is to realize in the following manner, its structure is by high-pressure intake pipe, ejector nozzle, the aeration Y-tube forms, 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 is bolted on 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, be provided with the flow-disturbing groove on the inwall of bend pipe.
On the aeration Y-tube, the bent angle of bend pipe is controlled at 10-40 °.
The beneficial effect that compared to the prior art combination high-efficiency fluidic device of the present invention is given prominence to is:
(1) greatly improved the contact area of gas-liquid two-phase due to the micro-bubble that produces in the flow process of gas-liquid in aeration Y-tube and aeration bend pipe, so oxygen transfer rate is high;
(2) air capacity can flexible and do not affect the effect of biochemistry pool mix and blend, and in addition, due to the handiness that this aerating apparatus tolerance is regulated, it is particularly suitable for lowering the joint oxygen-supplying amount to save energy consumption at anoxic, good oxygen condition;
(3) the applicable depth of water is generally 6-9m; Can reach 14, can save in a large number floor space;
(4) current of high speed with a large amount of kinetic energy, can be realized 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 different materials processing to make according to different sites, such as the aeration Y-tube can use stainless steel part, ironcasting or engineering plastics, 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, decrease production cost and use cost.
