Accompanying drawing explanation
Fig. 1 is embodiment 1 structural representation;
Fig. 2 is embodiment 2 structural representation.
Specific embodiment 1
Below in conjunction with accompanying drawing, structure of the present invention is done to detailed explanation and explanation, but be not the restriction to structure of the present invention, be specifically divided into two embodiments and describe.
Embodiment 1
Refer to Fig. 1, it is this structural representation of implementing related energy saving centrifugal ventilator.This energy saving centrifugal ventilator comprises drive motor 101, Blower Housing 102, suction port 103, relief opening 104, enterprising tracheae 201, lower inlet duct 202, outlet pipe 203, augmenter 30, gas treatment chamber 40 and spraying device 6.
The Blower Housing 102 of inlet 103 and relief opening 104 is for sealing draught fan impeller, and drive motor 101 rotates for drives impeller, by wheel rotation, drives gas directional flow.Wherein, the main function components that drive motor 101, impeller and Blower Housing 102 are centrifugal blower.In order to realize object of the present invention, suction port 103 is separately positioned on Blower Housing 102 front panels and rear sidewall with relief opening 104.For fear of gas, by suction port 103, after the main fan parts such as impeller, directly by relief opening 104, discharged, not in the same horizontal line, namely, suction port 103 staggers with relief opening 104 height the central point of suction port 103 and relief opening 104.In order to realize best effect, the center line of the center line of suction port 103 and draught fan impeller wheel shaft is contour.
Air output for the improvement raising centrifugal blower by structure.Relief opening 104 peripheral hardwares are useful on the augmenter 30 that forces gas to gather to outlet, and augmenter 30 is best and relief opening 104 is one-body molded.Augmenter 30 is diverging duct, and its inner tube wall slopes inwardly to force gas to gather from relief opening 104 gradually.Flaring opening is connected with relief opening 104, and flaring bottom is gas outlet 301.In order to reach best effect, the tube wall of augmenter 30 and horizontal angle are 1≤38 ° of 1,28 °≤β of β, preferably 28 °.Prove through test of many times, the tube wall length H1 of augmenter be 83 ?1000mm, can realize best effect.
The outlet end 202 of enterprising tracheae 201 laterally runs through Blower Housing 102 and is plugged in augmenter 30, for passing through augmenter 30 by gas channeling gas treatment chamber 40.The outlet of enterprising tracheae 201 is just positioned at gas outlet 301 places and flushes with gas outlet 301.For fear of impacting enter the air-flow of Blower Housing 102 from lower inlet duct, enterprising tracheae 201 is preferably positioned at the bore that augmenter pipe external diameter middle and enterprising tracheae 201 is less than gas outlet 301, and the length a1 of enterprising tracheae external diameter is 128 ?2000mm, the interior electrical path length a2 of gas outlet 301 is 156 ?2500mm.The entrance of enterprising tracheae 201 is connected with lower inlet duct 202 and forms total inlet pipe 9, and the outlet of total inlet pipe 9 is communicated with upper and lower suction tude respectively, and its entrance is communicated with pending gas.
Because the outlet of lower inlet duct 202 is connected with suction port 103.Like this, the pending gas that total inlet pipe 9 sucks just can enter gas treatment chamber 40 via upper and lower suction tude.Thus, the energy-efficient centrifugal blower that the present embodiment is related is higher and do not affect the gas of service life of fan applicable to humidity.
Below another embodiment of the present invention is described in detail, this blower fan structure is applicable to process has corrosivity or the gas that meeting exerts an influence to service life of fan such as viscosity is larger.
Refer to Fig. 2, it is this structural representation of implementing related energy-efficient centrifugal blower.This energy-efficient centrifugal blower comprises drive motor 101, Blower Housing 102, suction port 103, relief opening 104, enterprising tracheae 201, lower inlet duct 202, outlet pipe 203, augmenter 30, gas treatment chamber 40 and spraying device 6.
The Blower Housing 102 of inlet 103 and relief opening 104 is for sealing draught fan impeller, and drive motor 101 rotates for drives impeller, by wheel rotation, drives gas directional flow.Wherein, the main function components that drive motor 101, impeller and Blower Housing 102 are centrifugal blower.In order to realize object of the present invention, suction port 103 is separately positioned on Blower Housing 102 front panels and rear sidewall with relief opening 104.For fear of gas, by suction port 103, after the main fan parts such as impeller, directly by relief opening 104, discharged, not in the same horizontal line, namely, suction port 103 staggers with relief opening 104 height the central point of suction port 103 and relief opening 104.In order to realize best effect, the center line of the center line of suction port 103 and draught fan impeller wheel shaft is contour.
In order to realize object of the present invention, the entrance of enterprising tracheae 201 is communicated with pending gas, and its outlet end 3 laterally runs through Blower Housing 102 and is plugged in augmenter 30, for passing through augmenter 30 by the direct directional later exhaust treatment chamber 40 of pending gas.The outlet of enterprising tracheae 201 is just positioned at gas outlet 301 places and aligns in the vertical direction with gas outlet 301.In order to enter the air-flow of Blower Housing 102 to lower inlet duct, provide passage, enterprising tracheae 201 is preferably positioned at the bore that augmenter pipe external diameter middle and enterprising tracheae 201 is less than gas outlet 301.The length a1 of enterprising tracheae external diameter is 128 ?2000mm, and gas outlet 301 bore length a2 are 156 ?2500mm.
The entrance of lower inlet duct 202 is communicated with atmosphere, its outlet end is connected with suction port 103 and forms air-flow path, thereby by air guide augmenter, utilize negative pressure that centrifugal blower produces to drive pending gas in enterprising tracheae discharged to gas treatment chamber 40 by draught fan impeller and Blower Housing.
Air output for the improvement raising centrifugal blower by structure.Relief opening 104 peripheral hardwares are useful on the augmenter 30 that forces gas to gather to outlet, and augmenter 30 is best and relief opening 104 is one-body molded.Augmenter 30 is diverging duct, and its inner tube wall slopes inwardly to force gas to gather from relief opening 104 gradually.Flaring opening is connected with relief opening 104, and flaring bottom is gas outlet 301.In order to reach best effect, the tube wall of augmenter 30 and horizontal angle are 1≤38 ° of 1,28 °≤β of β, preferably 28 °.Prove through test of many times, the tube wall length H1 of augmenter be 83 ?1000mm, can realize best effect.
Principle of the present invention is: first by senior middle school's low pressure centrifugal fan, the air being communicated with lower inlet duct 202 is transported to the air chamber 4 at Blower Housing top, when the air in air chamber 4 passes through augmenter 30, the jet-action producing while accelerating air due to augmenter, air converges in gas outlet 301 places of augmenter 30, the dynamic pressure now producing in accelerating jetting surrounds the outlet end of enterprising tracheae, add the effect of the outward-dipping formed promotion diffusion of tube wall of gas treatment chamber 40, just enterprising endotracheal pending gas is attracted in gas treatment chamber, finally after empty spraying device purified treatment, be discharged in atmosphere.
