Gradual change runner, one end connecting line, the other end connect rectification section 3, the smooth transition of pipeline and rectification section 3 are realized, due to liquid
When entering rectification section 3 by preceding diffuser 2, the VELOCITY DISTRIBUTION on shaft section is uneven, and such as Fig. 6, rectification is equipped in rectification section 3
Device 24, rectifier 24 are formed side by side by many rectangular, prismatic small pipelines of round or hexagon, and are passed through resistance between small pipeline
Buddhist nun's net 25 is fixed, large eddies that may be present in former big runner is divided into small scale vortex, small scale vortex has faster
The rate of decay, this will accelerate water flow in vortex decaying, it is highly beneficial to the reduction of the stabilization and turbulivity of downstream water flow, from
And play the role of decay vortex, reduction turbulivity；The other end of rectification section 3 connects contraction section 4, and contraction section 4 is also one
Gradient tube is smoothly connected contraction section 4 and bubble segment occurred 9, and water flow enters bubble segment occurred 9 after contraction section 4 uniformly accelerates,
Contraction section 4 accelerates uniform fluid flow, reduces hydrodynamic noise and energy saving；As shown in figure 3, bubble segment occurred 9 is one equal
Even straight tube, in bubble segment occurred 9 close to water inlet, i.e., position close to contraction section 4 is equipped in the inside of bubble segment occurred 9
One medicine ball 18, for medicine ball 18 by being fixedly connected between fixator 19 and the tube wall 8 of bubble segment occurred 9, fixator 19 can
To be passed through using bolt, tube wall 8 is fixed with medicine ball 18, and medicine ball 18 forms a circle between the tube wall 8 of bubble segment occurred 9
Equidistant gap, the gap between medicine ball and the tube wall of bubble segment occurred should be maintained at 0.0675D, and wherein D is pipe wall internal diameters.
As shown in figure 4, being equipped with a tubule one in 18 vertical direction of medicine ball, tubule always wears solid 18 centre of sphere of bulbus cordis and gas
9 tube wall 8 of segment occurred is steeped, one end of tubule one is admission line 6, and other end is water inlet line 7, in admission line 6 and water inlet
Valve A5 is respectively equipped on pipeline 7；Crossing the centre of sphere of medicine ball 18, horizontally toward water inlet end is equipped with an other tubule two, tubule two
One end be connected to tubule one, inside tubule two be gas-liquid mixed pipeline 20；It is broken that the other end of the tubule two is provided with bubble
Millstone 21；As shown in figure 5, bubble breaker 21 is transverse slat array distribution laterally and longitudinally, formed in the horizontal direction side by side
Channel,；The other end of bubble segment occurred 9 passes through the realization of after-contraction section 10 of gradation type and being smoothly connected for pipeline；In after-contraction
Flowmeter 11 is additionally provided on pipeline after section 10；It may be equipped with dissolved oxygen detector 16 and blender 17 in water storage system.
For clearer explanation technical solution of the present invention, make further solution below in conjunction with the course of work of the invention
It releases:
During the work time, it is first turned on valve B12 and valve C14, when liquid is full of entire circulation loop, unlatching is followed
Ring pump 1, all setting in motions of the liquid in circuit, liquid enter rectification section 3 by the preceding diffuser 2 of gradation type at this time, and process is whole
It flows section 3 and large eddies that may be present in former pipeline is divided into small scale vortex, reduce turbulivity, obtain stable water
Stream enters contraction section 4, and water flow enters bubble segment occurred 9 after contraction section 4 uniformly accelerates；
Valve A5 is opened simultaneously, is passed through gas from admission line 6, is passed through water flow, this gas liquid mixture from water inlet line 7
It is discharged from gas-liquid mixed pipeline 20 towards inlet end, gas can be made by the bubble breaker 21 of 20 end of gas-liquid mixed pipeline
The original dimension of bubble is smaller, realizes that the first stage is broken, generates mother-qi bubble 22；Under the flow action flowed into pipeline, the gas
Liquid mixture goes downstream, at the gap passed through between medicine ball 18 and tube wall 8, according to principle of hydrodynamics, due to reality
Bulbus cordis 18 and tube wall 8 are apart from smaller, and speed increased dramatically when liquid stream passes through the region, and 18 downstream environmental pressure of medicine ball subtracts rapidly
It is small, under the conditions of not needing very high water velocity, strong shear flow can be formed, in medicine ball and wall surface immediate area high speed
Under water flow shear action, it is broken that second stage occurs for bubble；And there is high intensity in the downstream back side wake zone of medicine ball 18
Turbulence pulsation and vortex shearing, realize that the phase III of bubble is broken under 18 wake flow high intensity turbulent perturbation action of medicine ball
Broken, bubble is broken into rapidly a series of broken bubble of spray patterns when entering the region, and bubble size reaches micron order even at this time
Nanoscale obtains microbubble 15, and when bubble enters in water storage system, the stirring action of blender 17 disperses bubble preferably
In water environment, underwater bubble parameter is monitored using dissolved oxygen amount monitor 16.By lacking to what is extracted in water storage system
Amount water, which carries out quality testing, can obtain the purifying water effect of bubble.
Upper embodiment is merely to illustrate design philosophy and feature of the invention, and its object is to make technology people in the art
