Description
Technical field
The present invention relates to technical field of air purification, be specifically related to a kind of transformation air draft system for purification of air.
Background technology
In air purification field, the contaminated air of air pollution point is discharged by conventional air draft system.In prior art, air draft system drives several air port air draughts by a main air blower, because the distance of each inlet scoop is different, and the air quantity of each inlet scoop is different, each inlet scoop efficiency disunity of whole air draft system can be caused, thus make air purification effect bad, and the energy consumption of blower fan is higher.
Summary of the invention
The object of the invention is to overcome above-mentioned technical problem, a kind of air quantity that can adjust blower fan according to actual air volume is provided, there is the transformation air draft system for purification of air of the advantages such as energy consumption is little, contaminated air collecting amount is large.
Technical scheme of the present invention is:
For a transformation air draft system for purification of air, they several arms comprising air main, be connected with air main, described each arm is provided with an induced-draught fan and unidirectional air-valve, and described unidirectional air-valve is arranged on the air outlet side of described induced-draught fan; Described air main is provided with a guiding blower fan, the air outlet side of described guiding blower fan does not arrange described arm; The air inlet side being positioned at described induced-draught fan in described each arm is provided with a pressure sensor, and described pressure sensor all links with corresponding described induced-draught fan, the blower fan that leads.
Further, described induced-draught fan is arranged near described air main side.
Further, one end of described each arm is provided with air trapping cover, and described air trapping cover is positioned at the air inlet side of described induced-draught fan.
Further, described pressure sensor is positioned at the air outlet place of described air trapping cover.
Further, described tube section is circular, and described unidirectional air-valve profile is circular.
Further, described tube section is square, and described unidirectional air-valve profile is square.
Transformation air draft system for purification of air provided by the invention, adopt, on each arm, an induced-draught fan and unidirectional air-valve are installed, the air inlet side being positioned at induced-draught fan in each arm is provided with a pressure sensor, pressure sensor all links with corresponding induced-draught fan, the blower fan that leads.In use, the inlet scoop blast adjustment air force that each induced-draught fan can detect according to the pressure sensor of correspondence, the contaminated air of each inlet scoop is delivered in air main through induced-draught fan, under the draw of guiding blower fan, contaminated air forms orderly fluid in air main, discharges after treatment.Wherein, the air force of induced-draught fan determines the aperture of unidirectional air-valve, and when air quantity is large, unidirectional valve area is large, air quantity hour, and unidirectional valve area is little, and when induced-draught fan quits work, unidirectional air-valve cuts out.In this technical scheme, the Main Function of guiding blower fan is to provide tractive force, and the wind that each induced-draught fan is sent forms orderly fluid, flow by certain flow direction, therefore, the air quantity needed for guiding blower fan reality is far smaller than the situation as main air blower in prior art, and required energy consumption is low.And pressure sensor and corresponding induced-draught fan, guiding fan linkage, guiding blower fan is according to the actual blast of each inlet scoop, calculate Air Quantity Required, then air quantity and the power of guiding blower fan is automatically regulated in real time, make this air draft system be transformation air draft system, thus can realize being issued to the maximum object of contaminated air collecting amount in lowest energy consumption.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention for the transformation air draft system of purification of air;
Reference numeral: 1-air main, 2-arm, 3-induced-draught fan, the unidirectional air-valve of 4-, 5-leads blower fan, 6-air trapping cover.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Detailed description of the invention
Composition graphs 1, a kind of transformation air draft system for purification of air, several arms 2 comprise air main 1, being connected with air main, each arm 2 are provided with an induced-draught fan 3 and unidirectional air-valve 4, and unidirectional air-valve 4 is arranged on the air outlet side of induced-draught fan 3; Air main 1 is provided with a guiding blower fan 5, the air outlet side of guiding blower fan 5 does not arrange arm 2; The air inlet side being positioned at induced-draught fan in each arm 2 is provided with a pressure sensor, and pressure sensor all links with corresponding induced-draught fan, the blower fan that leads.The structure of pressure sensor is not provided in accompanying drawing; Arrow in accompanying drawing represents the air-flow direction in air main.
In use, the inlet scoop blast adjustment air force that each induced-draught fan can detect according to the pressure sensor of correspondence, the contaminated air of each inlet scoop is delivered in air main through induced-draught fan, under the draw of guiding blower fan, contaminated air forms orderly fluid in air main, discharges after treatment.Wherein, the air force of induced-draught fan determines the aperture of unidirectional air-valve, and when air quantity is large, unidirectional valve area is large, air quantity hour, and unidirectional valve area is little, and when induced-draught fan quits work, unidirectional air-valve cuts out.In this technical scheme, the Main Function of guiding blower fan is to provide tractive force, and the wind that each induced-draught fan is sent forms orderly fluid, flow by certain flow direction, therefore, the air quantity needed for guiding blower fan reality is far smaller than the situation as main air blower in prior art, and required energy consumption is low.And pressure sensor and corresponding induced-draught fan, guiding fan linkage, guiding blower fan is according to the actual blast of each inlet scoop, calculate Air Quantity Required, then air quantity and the power of guiding blower fan is automatically regulated in real time, make this air draft system be transformation air draft system, thus can realize being issued to the maximum object of contaminated air collecting amount in lowest energy consumption.
