Embodiment
A kind of jet bubble generator of cyclone air-flotation device, including body 1, body 1 are 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 are provided centrally with nozzle 2, suction casing 1.1
Side wall is provided with fluid inlet tube 3.Spiral shape spoiler 4 is provided with contraction section 1.2.Diffuser 1.3 is above provided with filter screen 4.Nozzle 2
Caused aqueous phase flow adjustment range is defined to 0.5 ~ 1.5m3/h.Gas phase flow rate adjustable range caused by suction casing 1.1 limits
It is set to 0.5 ~ 1.55m3/h.Maximum pressure limits position 0.2MPa in contraction section 1.2.The larynx mouth 1.3.1 of trunnion section 1.3 and nozzle 2
Be defined to 15 ~ 25mm apart from adjustable range.Contraction section 1.2 is from the conical pipe to diminish greatly, and taper is 35 degree.Diffuser 1.3
To become big conical pipe from small, taper is 15 degree.
Case history：
Embodiment 1：As shown in Figure 1, each part of device is connected, the Produced Liquid that waste water oil exploitation group provides,
Bubble result is directly observed by lucite tube：The bubble diameter of generating means release is more than 1mm；Bubble is intensive, overlapping tight
Weight；Bubble deformation is obvious, similar elliposoidal, and a large amount of air mass occurs, the generating means exit bubble of high-speed camera instrument shooting
Particle diameter is more than 3mm, running parameter such as table 1 below now：
The jet bubble generator initialization parameter of table 1
From the bubble diameter measured：Debugging working condition is not optimum condition.Analyze its reason：The gas-water ratio of setting is not
Properly, air flow rate is excessive；The larynx mouth distance 20mm of setting is not optimum value；The bubble of release is in lucite tube caliber
100mm insufficient space generates coalescence fully to spread.
Embodiment 2
As shown in Figure 1, each part of device, the Produced Liquid that waste water oil exploitation group provides are connected.
Operating condition adjustment is carried out regarding to the issue above：Reduce gas flow；Adjust nozzle and larynx mouth distance.Keep first
Larynx mouth distance 20mm is constant, reduces tolerance, and the operational factor after adjustment is shown in Table 2.The bubble of generating means release is away from outlet top
200mm, it is in reduction trend that the size of bubble declines with tolerance.Tolerance is 0.27m3During/h, air pocket number is reduced in photo, and
The overlapping decrease of bubble；When tolerance is down to 0.25m3/h（Mark condition）, bubble number significantly reduces, and overlapping phenomenon almost disappears.Therefore select
The operational factor detected by the use of operating mode 5 as bubble.
Table 2
Under the conditions of operating mode 5, adjustment nozzle and trunnion distance, the Air Bubble Size change of observation generator release；When both
Distance is gradually reduced, and air pocket quantity is reduced, the increase of minute bubbles density；Best results when nozzle and trunnion distance are 15mm.Respectively
Liquid level bubble ratio see the table below
The optimal operating parameter of jet bubble generator is that entrance water-carrying capacity is 1.28m3/ h, pressure 0.4MPa；Enter
Oral air flow is 0.25 m3/h（Mark condition）, pressure 0.3MPa, larynx mouth distance is set to 15mm.
