First air, Secondary Air Large Diameter Pipeline, low flow velocity pipeline meter play effect well in measuring.
Since the air pressure change of Venturi tube acts on, it is widely used in air-flow Mixed Design scheme.But due to fixation
Design can not meet adjustable the needs of optimizing.It is widely opened both at home and abroad using simple opening and closing scheme at present
Degree is adjusted, and can not be optimal the demand of design, meanwhile, also create additional design pressure.
Utility model content
In order to solve the above problem, the utility model provides a kind of Venturi pipe, by mainstream Venturi
The guide vane that trunnion section setting at least two is oppositely arranged, is set to mainstream Venturi tube to the guide vane adjustable tilt angle
To realize the opening size for adjusting Venturi tube on trunnion section tube wall, it is thus achieved that simple and convenient manipulation, and not will cause
Excessive design pressure.
The technical solution of the utility model is as follows: a kind of novel controllability venturi arrangement, including mainstream Venturi tube,
Mainstream Venturi tube includes contraction section, trunnion section and diffuser, is equipped at least two guide vanes being oppositely arranged in the trunnion section,
It is installed on the inner wall of trunnion section to the guide vane adjustable tilt angle, the top of the guide vane is equipped with spray equipment.
Preferably, the quantity of the guide vane is 2-8.
Specifically, the guide vane is fixedly connected on gear, and rotating electric machine is rotated by rack drives gear.
Specifically, the rotating electric machine axially connects a manual rocking handle.
Preferably, the cross-sectional shape of the trunnion section is rectangle.
Preferably, it is provided with convection current on the guide vane and takes offence and flows the diversion trench of progress water conservancy diversion.
The beneficial effects of the utility model are as follows:
1, at least two guide vanes, the guide vane adjustable tilt angle are arranged by the trunnion section in mainstream Venturi tube
It is set on the tube wall of trunnion section, the tilt angle by adjusting guide vane realizes that the opening size of control Venturi tube, structure are set
Meter is simple, easy to operate；
2, Venturi effect pipe adjustable range is effectively improved, and reduces mobility kinetic equation loss；
3, it can be widely applied to desulfurizing tower of electric power plant, system overall operation efficiency is improved in the fields such as ship desulfurizing tower.
Detailed description of the invention
With reference to the accompanying drawing, by the way that specific embodiment of the present utility model is described in detail, the utility model will be made
Technical solution and other beneficial effects are apparent.

Specific embodiment
Further to illustrate technological means and its effect that the utility model is taken, below in conjunction with the utility model
Preferred embodiment and its attached drawing are described in detail.It should be understood that technical solution discussed below is only explanatory, and do not have to
In the restriction protection scope of the utility model.
Referring to FIG. 1, showing a kind of novel controllability venturi arrangement, including mainstream Venturi tube, mainstream in figure
Venturi tube includes contraction section 110, trunnion section 120 and diffuser 130, is equipped at least two in the trunnion section 120 and sets in opposite directions
The guide vane 180 set is installed on the inner wall of trunnion section 120 to the 180 adjustable tilt angle of guide vane, the guide vane 180
Top is equipped with spray equipment 140.After air-flow passes through Venturi tube trunnion section 120, due to the presence of guide vane 180, gas volume meeting
It is amplified in a very short period of time, forms negative pressure, force to carry out rapid fusion with the solution sprayed.For desulfurization operations, liquid
Body absorbs the SO in air-flow2And dust, reach efficient dedusting and sulfur limitation effect.
Wherein, the quantity of the guide vane 180 is 2, in the other embodiments of the utility model, the guide vane 180
Quantity can be also other numbers within the scope of 2-8, preferably even number.The utility model mainly passes through adjusting guide vane
180 tilt angle, realizes the opening size for adjusting Venturi tube, i.e., the cross-sectional area that air-flow passes through is realized efficient.
Further, the novel controllability venturi arrangement further includes regulating mechanism, and the regulating mechanism includes tooth
Wheel 170, rack gear 160 and rotating electric machine 150a.
Specifically, the guide vane 180 is fixedly connected on gear 170, and rotating electric machine 150a is by rack gear 160 with moving gear
