Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The jet bubble generator of a kind of cyclone air-flotation device, including body 1, body 1 is divided into from left to right
Suction casing 1.1, contraction section 1.2, trunnion section 1.3 and diffuser 1.3, suction casing 1.1 is provided centrally with nozzle 2, suction casing 1.1
Sidewall is provided with fluid inlet tube 3.Spiral type flow-disturbing part 4 it is provided with in contraction section 1.2.Diffuser 1.3 is above provided with filter screen 4.Nozzle 2
Produced aqueous phase flow adjustment range is defined to 0.5 ~ 1.5m3/h.Gas phase flow rate range of accommodation limit produced by suction casing 1.1
It is set to 0.5 ~ 1.55m3/h.In contraction section 1.2, maximum pressure limits position 0.2MPa.The larynx mouth 1.3.1 of trunnion section 1.3 and nozzle 2
Distance range of accommodation be defined to 15 ~ 25mm.Contraction section 1.2 is from the conical pipe diminished greatly, and tapering is 35 degree.Diffuser 1.3
For the conical pipe big from little change, tapering is 15 degree.
Case history:
Embodiment 1: as shown in Figure 1, connects each parts of device, the Produced Liquid that waste water oil exploitation group provides, and passes through
Lucite tube directly observes bubble result: the bubble diameter of generating means release is more than 1mm；Bubble is intensive, overlapping serious；
Bubble deformation is obvious, similar elliposoidal, and a large amount of air mass occurs, the generating means exit bubble diameter of high-speed camera instrument shooting
More than 3mm, the such as table 1 below of running parameter now:
Table 1 jet bubble generator initialization parameter
Bubble diameter from recording: debugging working condition is not optimum condition.Analyze its reason: the gas-water ratio of setting does not conforms to
Suitable, air flow rate is excessive；Larynx mouth distance 20mm set is not optimum；The bubble of release is at lucite tube caliber 100mm
Insufficient space with fully diffusion, create coalescence.
Embodiment 2
As shown in Figure 1, connect each parts of device, the Produced Liquid that waste water oil exploitation group provides.
Operating condition adjustment is carried out for the problems referred to above:Reduce gas flow；Adjust nozzle and larynx mouth distance.First protect
Holding larynx mouth distance 20mm constant, reduce tolerance, the operational factor after adjustment is shown in Table 2.The bubble of generating means release is in outlet
Side 200mm, the size of bubble declines in reducing trend with tolerance.Tolerance is 0.27m3During/h, in photo, air pocket number reduces,
And bubble overlap weakens；When tolerance is down to 0.25m3/ h(marks condition), bubble number significantly reduces, and overlapping phenomenon almost disappears.Therefore
Select the operational factor that operating mode 5 detects as bubble.
Table 2
Under the conditions of operating mode 5, adjust nozzle and trunnion distance, observe the Air Bubble Size change of generator release；When both distances
Being gradually lowered, air pocket quantity reduces, and minute bubbles density increases；Nozzle and trunnion distance are best results during 15mm.Each liquid level
Bubble ratio see table
The optimal operating parameter of jet bubble generator be inlet water flow be 1.28m3/ h, pressure is 0.4MPa；Enter implication
Flow is 0.25 m3/ h(marks condition), pressure is 0.3MPa, and larynx mouth distance is set to 15mm.
