Preferably, the inflow end of exclusion body is cone shape, and its tip and flow direction point on the contrary, and/or the outflow end of exclusion body is cone shape, its sensing downstream, tip.
By accompanying drawing, the utility model is described below.
Accompanying drawing explanation
The content shown in detail at this is as follows:
Fig. 1 illustrates the first embodiment according to device of the present utility model;
Fig. 2 illustrates a part for accompanying drawing 1, i.e. venturi-contraction flow region and exclusion body;
Fig. 3 illustrates the schematic diagram of the alternative scheme of the end regions shown in Fig. 1.
Detailed description of the invention
Shown in Figure 1 comprises pipeline 1 according to device of the present utility model, and described pipeline has the import 2 for importing pending air-flow.The flow direction of air-flow represents with 11.
Pipeline 1 has venturi-contraction flow region 3.Streamwise 11 is seen, injection apparatus is positioned at before venturi-contraction flow region 3, and described injection apparatus comprises multiple nozzle 4 for being sprayed into by liquid in pipeline 1.Liquid is preferably water in this example.
Pipeline 1 surrounds exclusion body 5.Described exclusion body is arranged in pipeline 1 with one heart.The inflow end 12 of exclusion body 5 is in cone shape, and its tip and flow direction point on the contrary.The outflow end 13 of exclusion body 5 is equally in cone shape, and tip is pointed to and flowed out direction.
The formation annular gap, side of exclusion body 5 and pipeline 1.In addition, described exclusion body is configured with guide vane.Described guide vane is evenly distributed in the circumferentially whole of exclusion body 5.Also accompanying drawing 2 is seen.
In axial direction part, narrow positions 7 is positioned at exclusion body 5 downstream.Pipeline 1 narrows down to less diameter suddenly in this narrow positions.Then, pipeline 1 continues to extend with less diameter.At this, the entrance 14 of the pipeline 1 that diameter is less can upstream insert the diameter of pipeline 1 larger before certain distance (leaching principle of diving) within that section.Branch out tributary 15 in narrow positions 7, the section that wherein branch road 8 is larger with the diameter of pipeline 1 is tangentially connected, with reference to the right side cross-sectional view of accompanying drawing 1.
Substitute the end segments according to device of the present utility model shown in Figure 1, end segments also can design as shown in Figure 3.As can be seen, pipeline 1 is in capwise.At this, drowning pipe 9 stretches in pipeline 1.The import 10 of drowning pipe 9 is surrounded with one heart by pipeline 1.In addition, the tributary 15 separated preferably is made up of contaminated liquids.
Described device works as follows:
The import 2 of carrying the air circulation piping 1 of impurity enters.Air stream arrives at the flange of nozzle 4.Before described nozzle can be located in venturi-contraction flow region 3 or its inside.The high shear force now occurred between air and liquid causes being formed drop thin especially.Accumulation of impurities is on drop.Produced by the annular gap between exclusion body 5 and the inner surface of pipeline 1 and force speed.Exclusion body 5 serves as vortex generator together with its guide vane, and this vortex generator not only can improve flow velocity extraly, but also can improve air and the shearing force of drop carrying particle.Drop is divided in the shearing field between exclusion body 5 and pipeline 1 wall further.Thus, specific surface amplifies and absorbability raising.In annular gap liquid and dispersion or gaseous state dirt between free cross section diminish.Thus, the contact frequency between impurity and air to be clean improves.In addition, because the inertia of decentralized photo forces admixture of gas and impurity or droplets mixing in the region of exclusion body.All described effect all has active influence to cleansing power.
Guide vane 6 is arranged on exclusion body 5 in the embodiment shown.But also can alternatively be fixed on the inner surface of pipeline 1.
Carry out subsequently by the cleaning fluid drop of loading from the air flow rotated from being that principle according to following current cyclone separator is carried out.Here flowing into and flowing out is all carry out when not carrying out inside commutation.See accompanying drawing 3.
Exclusion body 5 preferably moves axially by adjusting device 16.If exclusion body disposable is adjusted to the axial location determined, then first it be that position is fixed.Fluid cross-section can be regulated according to service requirement thus in the spray site of water.
But following embodiment is also also admissible: pipeline 1 vertically extends in the region of exclusion body 5.Exclusion body such as need not be fixed to fixing environment by mechanical splice.Furtherly, squeezing body can freely-movable in stream, preferably only lower motion in the axial direction.In addition, also described exclusion body can be designed as the exclusion body 5 with guide vane 6 described before.The same n-back test of exclusion body that described exclusion body image position is fixing: the inner surface of the wall portion of itself and pipeline 1 forms annular gap; In addition, it produces eddy current.The weight of described exclusion body can be determined according to the actual requirements.But guider is set, although to make the axially-movable in pipeline 1 of exclusion body, ensure the rotary motion of air-flow here simultaneously.This can be realized by corresponding geometry (not shown), the such as groove passed through in exclusion body, and the guide plate be connected with the inner surface of pipeline 1 or spring are coupled in described groove.In such an embodiment, exclusion body also can bear the function of check-valves, or serves as the sealing unit of pipeline 1 under a no gas flow condition.
