Detailed description of the invention
With reference to the accompanying drawings the present invention is explained in more detail hereinafter, illustrative embodiments of the present invention shown in the drawings.
Fig. 1 shows the example with the fume exhauster system of built-in rotor according to illustrative embodiments.
As shown in fig. 1, the fume exhauster system 100 with built-in rotor will be discharged into outside to prevent the device of room air pollution in time by pollution generating means 10 produced pollution gas.
The fume exhauster system 100 with built-in rotor comprises housing 110, scavenger fan 120, rotor 130 and discharge portion 140.
Housing 110 be arranged on pollute generating means 10 upside on and there is the entrance 111 of the downside being formed at housing 110, flowed into by this entrance 111 by pollution generating means 10 produced pollution gas.
Housing 110 can be made up of stainless steel material, stainless steel is than the special steel with less carbon and excellent anti-corrosive properties with other Metal Phases, and stainless steel has good mechanical performance, high resistivity, low thermal conductivity, although and thickness be only aluminium three/for the moment just there is the intensity identical with aluminium.In addition, due to stainless hardness, it has good processing characteristics, and can perform soldering, thus makes it possible to process fast.
The material of housing 110 can according to having the structure of fume exhauster system 100 of built-in rotor and application target and changing.
Scavenger fan 120 is installed within the case 110, and is connected to rotating driving device 121.Thus, if rotating driving device 121 rotates, then scavenger fan 120 is also along with rotating driving device 121 rotates strongly to remove dusty gas.Rotating driving device 121 can be motor.
Rotor 130 is arranged on the axis identical with scavenger fan 120, and rotates to absorb dusty gas together with scavenger fan 120 by rotating driving device 121, thus preventing pollution gas is diffused into inside.Rotor 130 can be arranged on from the axis of rotary driving gear 121 extension.Rotor 130 can be installed to traditional fume exhauster system in addition, makes it possible to not change whole smoke exhaust ventilator, thus reduces installation cost.
Discharge portion 140 is arranged on the upper surface of housing 110, and contaminated air is guided to outside.Such as, once flow in entrance 111 by pollution generating means 10 produced pollution gas by rotor 130, then the dusty gas of inflow is discharged to the outside by discharge portion 140 by scavenger fan 120.
As mentioned above, the fume exhauster system 100 with built-in rotor has the extension axis of rotating driving device 121, and rotor 130 is arranged on the axis of extension, makes it possible to absorb rapidly by pollution generating means 10 produced pollution gas.In addition, rotor 130 can additionally be installed to traditional fume exhauster system, makes without the need to changing whole system, thus reduces installation cost.
Housing 110 can be formed as the conical by its shape with narrower top and wider bottom, to make when rotor 130 rotates to improve discharge efficiency by using with the round-shaped wind that blows.If the entrance 111 of housing 110 is formed as rectangular shape, then the square edge of the wind collision housing produced when rotor 130 rotates, thus cause the mobile obstacle of the motion of the dusty gas of the obstruction of such as eddy current and so on caused by rotor 130.
Therefore, there is the conical by its shape of narrower top and wider bottom by making housing 110 be formed as, easily can make by the dusty gas stream motion caused by rotor 130, thus can discharge efficiency be improved.
Fig. 2 shows the diagram of the scavenger fan taken out from Fig. 1.
As shown in Figure 2, scavenger fan 120 can be sirocco fan (sirocco fan).Sirocco fan is the centrifugal fan allowing air to circulate by the rotation of multiple forward blade, and because it causes very little noise, therefore it can in order to the object purified air or ventilate in the application widely from domestic environment to industrial environment.
Fig. 3 shows the view of the rotor taken out from Fig. 1.Fig. 4 is the stereogram of Fig. 3.
As shown in Figures 3 and 4, rotor 130 comprises axial core 131, first blade 132, body 133, second blade 134 and hole 135.
Axial core 131 be from rotating driving device 121 extend part and be connected to scavenger fan 130 by same axis.
First blade 132 is connected to axial core 131 with suction by pollution generating means 10 produced pollution gas.Such as, rotate to promote dusty gas towards scavenger fan 120 once the first blade 132, then the dusty gas at bottom place is just introduced in empty space, makes to be drawn in the entrance 111 of housing 110 by pollution generating means 10 produced pollution gas.
First blade 132 can be any form, as long as the first blade 132 can play a part to force the gas of bottom to arrive top.First blade 132 can for being connected to the torsional mode right angled triangle in the form of a truncated cone of axial core 131, or can for being attached to the airfoil shape of the support member connecting axial core 131 and body 133.In addition, the first blade 132 can for being attached to the blade shape of the inner side of body 133.That is, the shape of the first blade 132 can according to having the structure of fume exhauster system 100 of built-in rotor and application target and changing.
Body 133 can be connected to the upper and lower support member of axial core 131, and is formed as encirclement first blade 132.
Second blade 134 can be attached to the outer surface of body 133.Therefore, when body 133 rotates, prevent the dusty gas of discharging towards scavenger fan 120 top to be diffused into outside by centrifugal force.
Body 133 can for having the drum of unlimited upper and lower.Dusty gas is flowed into by the upper and lower opened wide, and the capture range of dusty gas can be made to narrow or broaden by the size changing opening.
Second blade 134 is formed on the outer surface of body 133, and produces wind by being rotated in bottom.Inclined surface in the wind produced and housing 110 collides to be collected in inner side, thus forms drift fence to produce eddy current and to manufacture heavy curtain effect.
In traditional fume exhauster system, be only scavenger fan 120 is installed within the case 110 carry out withdrawing air simply, thus prevent from being diffused into outside by pollution generating means 10 produced pollution gas.Dusty gas is remained on drift fence inside by this eddy current and heavy curtain effect, thus preventing pollution gas is diffused into outside.
Second blade 134 can be the right angled triangle of conically shape, but according to having the structure of fume exhauster system 100 and the application target of built-in rotor, second blade 134 can for having the shape of angle, or can be rectangle, circular arc or similar shape, as shown in Fig. 5 to Fig. 7.
Isolated multiple hole 135 can be formed in the body 133 of rotor 130.Because hole 135 is formed in the body 133 of rotor 130, therefore strongly the dusty gas flowed in rotor 130 can be discharged to the outside, thus more efficiently heavy curtain effect can be realized by the second blade 134 rotation.
Fig. 8 shows the view of the pressure distribution when not having rotor in Fig. 1.Fig. 9 is showed and is rotated by rotor and the view of pressure distribution in the Fig. 1 changed.Figure 10 shows the dusty gas of being discharged by the fume exhauster system in Fig. 8 view at scavenger fan and the mass rate of emission in polluting between generating means space.Figure 11 shows the view of the mass rate of emission in the dusty gas of being discharged by the fume exhauster system in Fig. 9 space between scavenger fan and pollution sources device.With reference to Fig. 8 to Figure 11 in the situation with rotor and do not have the discharge efficiency in the situation of rotating body to be described.
First, as shown in Figure 8, in the fume exhauster system not having rotor, form low pressure by the bottom being rotated in scavenger fan 120 of scavenger fan 120, and in discharge portion 140, form high pressure, make it possible to discharge by pollution generating means 10 produced pollution gas.But, if fume exhauster system is installed as distance pollute generating means 10 comparatively far, if or there is a large amount of dusty gas, then more weak suction force makes to be difficult to discharge dusty gas.
In order to solve this problem, by as shown in Figure 9 rotor 130 being arranged in fume exhauster system, form low pressure by the bottom being rotated in body 133 of the first blade 132 of rotor 130, and form slight high pressure at entrance 111 place, thus promote emissions operation.Therefore, the rotation of the first blade 132 makes the aspiration ranges gone up in a downward direction broaden, thus forces dusty gas to arrive scavenger fan 120, thus produces the effect can collecting dusty gas before dusty gas is diffused into household internal.
In addition, the flowing produced by the rotation of the second blade 134 of the outer surface being attached to body 133 forms collision housing 110 and the heavy curtain stream moved downward.Heavy curtain stream contributes to making the pollutant of bottom move upward to entrance 111, thus most pollutant is discharged by discharge portion 140.
By forming the downside support member of the helically oar shape in supporting body portion 133, more easily the dusty gas of bottom can be guided to discharge portion 140.
Figure 10 shows the dusty gas of being discharged by the fume exhauster system in Fig. 8 view at scavenger fan and the mass rate of emission in polluting between generating means space.By contrast Figure 10 and Figure 11, if when scavenger fan 120 runs in the fume exhauster system not having rotor 130, can find out that dusty gas there is no mass rate of emission in lower region.That is, the dusty gas in lower region can not be collected only by the motion of scavenger fan 120.In addition, the mass rate of emission mediated in region is also more weak, and only has the mass rate of emission in upper area can record out value.
But, as shown in figure 11, in the fume exhauster system with rotor 130, the mass rate of emission of dusty gas remains and is in higher than certain level by the eddy current produced by the motion of rotor 130, heavy curtain stream and suction streams, and the mass rate of emission in zone line for not having the twice of the mass rate of emission of the fume exhauster system of rotor 130 or more times, and can have excellent mass rate of emission in upper area.
Figure 12 shows the view of another example in the hole in Fig. 4.
As shown in figure 12, hole 235 can be formed as the shape of quadrangle, and can be positioned at the lower end of body 133.Hole 235 is not limited to the example that illustrates and can according to having the structure of fume exhauster system 100 of built-in rotor and application target and changing its shape and position.
Figure 13 shows the view of another example of the first blade in Fig. 4 and the second blade.
As shown in figure 13, the first blade 232 of rotor 130 and the second blade 234 can be formed as the shape of trapezoidal pyramidal.In addition, the first blade 232 can be formed as being spaced apart from each other in the inside of body 133.First blade 232 and the second blade 234 are positioned to, not in the face of each other, make it possible to more effectively aspirate dusty gas.
Be hereinbefore described multiple example.But, should be understood that and can make multiple amendment.Such as, if if perform described technology and/or the parts combined in a different manner in described system, configuration, device or loop with different orders and/or substitute or replenish the parts in described system, configuration, device or loop by other parts and their equivalent, suitable result can be realized.Therefore, other embodiment within the scope of the appended claims.In addition, above-mentioned example is used for exemplary explanation the present invention, and therefore, the present invention is not limited to this.
