Detailed description of the invention
Illustrate below in conjunction with the accompanying drawings and this utility model be described in more detail:
In conjunction with Fig. 1～4, structure of the present utility model as illustrated in figs. ia and ib, mix by aerosol type gas-liquid static state
Clutch mainly includes primary hybrid chamber 6, secondary hybrid chamber 12, atomizer 5, sphere baffle plate 7 and connection
Pipe 11.Atomizer 5 and sphere baffle plate 7 are installed in primary hybrid chamber 6, and primary hybrid chamber 6 is with secondary
Level hybrid chamber 12 was connected by communicating pipe 11.Blender cap 4 is provided with two gas accesses 1,2, permissible
Input multicomponent gas.
As shown in Figure 2,3, in primary hybrid chamber 6, communicating pipe 11 one end open, with sphere baffle plate 7
Connect.Communicating pipe 11 other end sealing, is positioned at secondary hybrid chamber 12.Under communicating pipe 11 sealed end pipe face
Side has Process, to form strong disturbance in secondary hybrid chamber 12.Process on communicating pipe 11
The gross area more than communicating pipe 11 arrival end sectional area, to reduce the throttle effect of pipeline.
Workflow of the present utility model: gas is entered primary hybrid chamber 6 by entrance 2, and liquid is by being atomized
Nozzle 5 sprays into primary blender 6, becomes misty liquid droplets.Due to the effect of inertia of spraying, misty liquid droplets meeting
It is scattered in Incoming gas.For making misty liquid droplets be scattered in uniformly among air-flow, the injection of atomizer 5
Axis overlaps with the central shaft of primary hybrid chamber 6.Air-flow flows through in primary hybrid chamber 5 together with misty liquid droplets
Sphere baffle plate 7, circulation area gradually decreases so that air-flow velocity increases.High velocity air is at primary hybrid chamber 6
Lower area flow direction changes, and forms strong flow-disturbing, completes the first mixing of gas-liquid.First gaseous mixture leads to
Spend communicating pipe 11, enter secondary hybrid chamber 12.Due to the Process structure of communicating pipe 11 end, air-flow
Strong flow-disturbing can be formed so that gas-liquid uniformly mixes at secondary hybrid chamber 12 lower area.Gaseous mixture is by secondary
Hybrid chamber 12 lower area, through the flowing of longer distance, flows out air and liquid mixer.Owing to secondary mixes
The sectional area in chamber 12 is less than primary hybrid chamber 6, so, gaseous mixture obtains good in secondary hybrid chamber 12
Buffering, eliminate airflow fluctuation, finally give stable homogeneous mixture.
This utility model gas-liquid static mixer uses double cavity structure, primary hybrid chamber and secondary hybrid chamber.Just
Level hybrid chamber is built with atomizer and sphere baffle plate；Primary hybrid chamber is connected by pipeline with secondary hybrid chamber.
In static mixer, gas is entered blender primary hybrid chamber by pipeline, and liquid is then by being arranged on primary
Nozzle in hybrid chamber sprays into blender.Due to the effect of inertia of spraying, can be formed certain in primary hybrid chamber
The disturbance of intensity so that misty liquid droplets is dispersed among gas.Sphere baffle plate in primary hybrid chamber can play
Certain throttling action so that gas actual internal area reduces, flow velocity increases.Gaseous mixture is in baffle plate rear surface regions
Interior formation strong disturbance, thus promote gas-liquid mixed, complete primary mixing.Equipped with connecting pipe on baffle plate,
To connect two hybrid chambers.The end surface of communicating pipe has uniform Process, and gaseous mixture is entered by aperture
Enter secondary hybrid chamber.In order to reduce total throttle effect of aperture, aperture area sum is cut more than communicating pipe opening
Area.Gaseous mixture can form strong disturbance in secondary hybrid chamber lower end area after flowing out aperture, thus promotes gas
Liquid secondary mixes, and is finally completed the mixed process of gas-liquid.The sectional area of secondary hybrid chamber is less than primary mixing
Chamber so that secondary gaseous mixture obtains total caching in hybrid chamber upper area, eliminates the pressure oscillation of air-flow.
This utility model uses double cavity structure, to improve air-flow mixed effect, reduces space utilization rate.
Atomizer described in the utility model is installed on the central axis of primary hybrid chamber, with profit to greatest extent
With the effect of inertia of atomized drop so that it is be dispersed in Incoming gas.
Primary hybrid chamber described in the utility model, built with sphere baffle plate, to reduce air-flow fluid cross-section, improves
Air-flow velocity.
Communicating pipe described in the utility model is installed on sphere baffle plate, changes air current flow direction, just
Form strong disturbance bottom level blender, promote gas-liquid mixed.
The end of communicating pipe described in the utility model has Process, and opening area accounts for the 1/2 of whole circle,
And opening area is positioned at pipeline lower surface, to strengthen the disturbance of air-flow.The aperture gross area amasss more than pipeline section,
To reduce throttle effect.
This utility model uses double cavity structure, including primary hybrid chamber and secondary hybrid chamber, secondary hybrid chamber
Sectional area is the 1/3 of primary hybrid chamber.Primary hybrid chamber is built with atomizer and sphere baffle plate；Primary mixed
Close chamber to be connected by pipeline with secondary hybrid chamber.It is installed on communicating pipe on sphere baffle plate, and the end of communicating pipe
End has Process, and opening area is positioned at pipeline lower surface, accounts for the 1/2 of whole circle.
