Description
Technical field
The utility model relates to a kind of Mechanical aerator, particularly relates to a kind of external-type two-stage pressurization efficient jet aerator.
Background technology
Aeration refers to adopt corresponding equipment and technical measures, and airborne oxygen is transferred in the mixed solution and the process utilized by microorganism.The aerations that adopt both at home and abroad at present have the air blast-mechanical aeration of blast aeration, mechanical aeration and both associatings more.To be the pressurized air that will be sent by air compressor machine deliver to the air-diffuser (aerating apparatus) that is installed at the bottom of the aeration tank by a series of tubing system in blast aeration, air is overflowed with the form of micro-bubble therefrom, and in mixed solution, spread, oxygen in the bubble is transferred in the mixed solution gone; And bubble makes mixed solution be in violent mixing, whipped state in the strong diffusion of mixed solution, stirring.Mechanical aeration then utilizes and is installed in the upper and lower impeller high speed rotating of the water surface, churns the surface tempestuously, produces hydraulic jump, and the surface of liquid level and contact with air is constantly updated, and airborne oxygen is transferred in the mixed solution gone.At present in the art, outside twin-stage type boosting efficient aerator does not also appear.
Summary of the invention
The purpose of this utility model provides a kind of external-type two-stage pressurization efficient jet aerator for above-mentioned the deficiencies in the prior art part exactly, can be applied in the MBR(membrane bioreactor), the SBR(sequencing batch reactor), MJBR(jetting type membrane bioreactor) and contact oxidation technology in, and reach and increase the aeration degree of depth, enlarge the aeration scope, guarantee the effect of efficient oxygen transfer efficiency.
The purpose of this utility model realizes in the following way: a kind of external-type two-stage pressurization efficient jet aerator, comprise housing, and series connection arranges two-way jet pipeline in the housing.
Further, each road jet pipeline includes power jet, is taken out medium input channel, hybrid chamber and diffuser pipe, power jet, hybrid chamber are connected with diffuser pipe and are connected, taken out the junction that the medium input channel is arranged on power jet and hybrid chamber, diminish gradually along medium flowing direction hybrid chamber internal diameter, it is large that the diffuser pipe internal diameter becomes gradually.
As preferably, hybrid chamber is connected with the diffuser pipe reducing.
As preferably, taken out medium input channel and medium flowing axis of orientation and kept 75 ° of angles.
As preferably, described power jet is the conical hollow spray nozzle.
Further, described being taken out is equipped with caloic inserted-link type under meter in the medium input channel.
Further, described being taken out in the medium input channel is equipped with pressure unit.
Further, the medium discharge outlet of described housing is provided with the anti-clogging plug spiral nozzle.
In aeration system, because the high oxygen requirement of organic sewage and the increase of novel biochemical waste disposal plant height, through the two-step supercharging jet aerator, from energy point of view, the efficient of ejector can be higher.When sewage passes through power jet through the jet-loop pump, along with the flow passage transverse section changes, the pressure drop in nozzle, speed increases, and occurs minimum micro-vacuum pressure zone behind jetting nozzle.Air is inhaled into sewage and mixes in hybrid chamber, and the momentum transfer of sewage has been given air.In diffuser pipe, the Speed Reduction of mixed stream, kinetic transformation becomes pressure energy.Behind the two-stage passage, pressure energy improves again, and the content of air is also along with increase, and this moment, mixed flow overcame the counterpressure of outlet, and mixing wastewater with air stream is entered in the aeration environment by ejector.
Compared with prior art, the beneficial effects of the utility model are:
1, by two-step supercharging, improved the ratio of mixture of empty G﹠W, can improve the aeration degree of depth of this utility model device, increase the scope of exposing to the sun, reduce machinery such as the input of the mechanical means such as gas blower, air compressor machine;
2, owing to be provided with the two-way air input passage, increased the input of air, guaranteed the abundant mixing of sewage and air in efficient oxygen transfer efficiency and the aeration tank;
3, because the setting of two-step supercharging passage, the mixed flow of empty G﹠W can produce certain temperature rise in the pipeline input process, improve the spread coefficient of oxygen, make oxygen sewage the aeration tank obtain higher transfer efficiency from face, further improved the aeration effect;
4, reduce input cost, non-maintaining, can design various size and size according to customer requirement.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, a kind of external-type two-stage pressurization efficient jet aerator, the tubular shell 10 that comprises stainless steel sets gradually one-level power jet 1, one-level hybrid chamber 2, one-level diffuser pipe 3, second motive force nozzle 4, secondary hybrid chamber 5 and secondary diffuser pipe 6 in the housing 10.Wherein, along the medium flowing direction, one-level hybrid chamber 2 and secondary hybrid chamber 5 internal diameters diminish gradually, and one-level diffuser pipe 3 and secondary diffuser pipe 6 internal diameters become large gradually.One-level hybrid chamber 2 is connected with one-level diffuser pipe 3 reducings, and secondary hybrid chamber 5 is connected with secondary diffuser pipe 6 reducings.One-level is taken out medium input channel 8 and is tilted 75 ° to be connected between one-level power jet 1 and the one-level hybrid chamber 2 along the medium flowing axis of orientation, and secondary is taken out medium input channel 9 along the medium flowing direction
Axle tilts 75 ° and is connected between second motive force nozzle 4 and the secondary hybrid chamber 5.
Described one-level power jet 1 and second motive force nozzle 4 are the conical hollow spray nozzle.One-level is taken out medium input channel 8 and secondary and is taken out caloic inserted-link type under meter and pressure unit all are installed in the medium input channel 9.Medium discharge outlet at housing 10 is provided with anti-clogging plug spiral nozzle 7.
The utility model is under the centrifugation of jet-loop pump, the sewage mixture is delivered into jet aerator, by one-level power jet 1 the sewage mixture is delivered to the jet pipeline, when sewage passes through, along with flow channel cross changes, pressure drop in one-level power jet 1, speed increases, in the minimum micro-vacuum zone of ejection one-level power jet 1 rear appearance.Air is inhaled into, because power jet is furnished with the anti-clogging plug spiral, air is cut into countless tiny bubbles, mixes in one-level hybrid chamber 2 with the sewage mixture, and the momentum transfer of sewage has been given air.In one-level diffuser pipe 3, the Speed Reduction of mixed stream, kinetic transformation are the pressure energy of fluid; Then mixed stream enters the secondary jets pipeline, through second motive force nozzle 4, principle is the same, the pressure drop of mixed stream in second motive force nozzle 4, speed increases, the static pressure district appears after causing second motive force nozzle 4, air is inhaled into again, with mixed flow in 2 interior mixing of secondary hybrid chamber, be pressure energy through the kinetic transformation of mixed stream behind the secondary diffuser pipe 6, through discharge outlet, under the effect of anti-clogging plug spiral nozzle 7, mixed stream is cut into countless tiny bubbles, overcomes the counterpressure of outlet, mixes bubble and is injected in the aeration tank with the high turbulence state.In the operational process, air flow quantity and intake pressure in thermal mass flowmeter, the pressure unit on-line monitoring air line, the normal operation of effective guarantee equipment.This example also can be used in the hybrid technique of aeration tank, utilizes valve closes air intake passage, need not agitator, guarantees step nitrated and denitrifying generation.
