Figure 11 (A) represents the shape in the hole 11 of the filter 10 of the present embodiment.Figure 11 (A2) is the void of the circle of Figure 11 (A1)
Enlarged drawing (following, identical in detail in this figure) in line.The hole 11 of filter 10 generally circular in shape, the diameter in hole 11 is about 0.75
～5mm.Hole 11 on discoid filter 10 is as shown in figure (A1), and be arranged in centered on the center of rotation of disk is concentric
Round shape.But, the shape in hole, size, arrangement are not particularly limited.For example, the arrangement in hole also can be that hole is opened in positive triangle
It is opened on the summit of shape, by hole on foursquare summit or any type of arrangements such as random perforate brokenly.In addition,
The shape in hole is in addition to change case shown below, it is also possible to be any shape of triangle, square, regular polygon etc..
Figure 11 (B)～(E) represents the change case of the shape in hole.As shown in Figure 11 (B), the shape of hole 11a is discoid
The ellipse in the radial direction with long diameter of filter.In this change case, short diameter and long diameter ratio are 1:2.2
Left and right, but it is not limited to this.Hole 11a is the same with (A), is arranged in the concentric circles centered on the center of rotation of disk, but simultaneously
It is not limited to this.
As shown in Figure 11 (C), the shape of hole 11b is to have the ellipse of short diameter in the radial direction at discoid filter
Circular.In this change case, short diameter and long diameter ratio are about 1:2.4, but are not limited to this.Hole 11b and figure (B)
Sample, is arranged in the concentric circles centered on the center of rotation of disk, but is not limited to this.
As shown in Figure 11 (D), the shape of hole 11c is rectangle.In this change case, minor face is 1:3.5 with the ratio on long limit
Left and right, but it is not limited to this.The direction on the long limit of hole 11c becomes neither radial direction, be not the angle of circumferencial direction, but simultaneously
Being not limited to this, the direction on for example long limit is that radial direction also may be used.
As shown in Figure 11 (E), the shape of hole 11d is irregular polygon.It is formed like being combined with rectangle and triangle
Shape as shape, vertex of a triangle is towards the shape of rotation direction, but is not limited to this, it is also possible to be the top of triangle
Point is towards the direction contrary with rotation direction.
In addition, on a filter, both can possess the hole of a kind of shape within above-mentioned, it is also possible to combination is wherein
The hole of two or more shapes.In addition, utilize formed lug form hole (gap) in the case of, it is also possible to described
Hole (gap) have together as slotted filter device on such protruding pinna.
On filter, the region of providing holes can be the whole face of filter, it is also possible to be a part.In a part of situation
Under, the region of providing holes can be that (that is, the region close to center of rotation does not sets for the region of the outer peripheral edge close to disc-shaped filter device
Put hole), on the contrary, it is also possible to be that (that is, the region close to outer peripheral edge is not provided with for the region of center of rotation close to disc filter
Hole).But, if the shape/size in hole is identical, then the velocity of rotation close to a side of outer peripheral edge is fast, it is therefore preferable that
Region providing holes close to the outer peripheral edge of disk filter.
So-called hole bore DA (m) in a circumferential direction as shown in Figure 11, refers in the crosscutting rotation with filter
The maximum of the length of the arc being clipped by the two ends in hole in the concentric circles in the hole centered on center.In addition, so-called aperture is passed through
Time, DA/Vx (second) table in the case of setting the peripheral speed at distance Rx (m) place of distance center of rotation as Vx (m/ second)
Reach.In addition, so-called aperture averaging is to be averaged aperture by the time in the range of filter is all by time tx (second)
Time, represent by (1) formula.Here, set the radius in the outside in the region that there is hole on filter as Rmax (m), if filter
On there is hole the radius of inner side in region be Rmin (m), if the revolution per second of filter is the N (/ second), if the angle of filter
Speed is ω (radian per second).Exist with concentric circles centered on rotary shaft in addition, set the region that there is hole on filter, and
And hole is uniformly distributed in this region.If aperture is DA/2 π NRx by the time, as follows by time tx at aperture averaging.
In addition, aperture averaging by the time in other words, be the hole bore in a circumferential direction of filter one end and
The other end passes through the mean value on the filter of the time required for certain point on circumference, also can refer to for convenience's sake
Exist on the region in hole, move the hole in the identical radial location of the crosscutting area being positioned on inner side and outer side and in circumference side
The time required for length of the length of arc upwards, i.e. moving hole bore in a circumferential direction.Carry out with reference to Figure 11 (A2)
Explanation.Circular hole 11 is while describing camber line from left to right when seeing in the drawings centered on the pivot (not shown) of filter
Speed with V (m/ second) moves in a circumferential direction on one side.Point α and some β is same on the periphery in hole 11 and at pivot
Point on one circumference, some γ is the midpoint of arc α β.Therefore, put α and some β become hole 11 bore in a circumferential direction one end and
The other end.
Hole 11 bore in a circumferential direction is long by the camber line folded by the two ends in hole 11 in the concentric circles in crosscutting hole 11
The maximum of degree, therefore, the length of arc α β becomes the situation that maximum is at point of contact α and the diameter that the straight line putting β is hole 11.
In the case, a length of DA of arc α γ β.One end (some α) of hole 11 bore in a circumferential direction and the other end (some β) are logical
The time required for the certain point on circumference (some γ) that crosses refers to, from a β by a γ start to a α by a γ when
Between.In addition, radius in the outside setting the region that there is hole on filter is as Rmax (not shown), if there is hole on filter
In the case that the radius of the inner side in region is Rmin (not shown), the region that there is hole refers in the outside of Rmin and Rmax's
The region that inner side, width are (Rmax-Rmin).In addition, radial location Rctr making the area of inner and outer identical (is not schemed
Show) meet following formula.
πRmax2-π Rctr2=π Rctr2-π Rmin2
In addition, peripheral speed Vav in hole 11 also can by the interval from Rmin to Rmax to being arranged in filter
Pivot centered on same circumference on the aggregate value of peripheral speed of particle be integrated, and by integrated value divided by mistake
The area in the region (region from Rmin to Rmax) that there is hole on filter is tried to achieve.Specifically, peripheral speed Vav in hole 11 is full
Foot formula.
Vav=4 π N (Rmax2+RmaxRmin+Rmin2)/3(Rmax+Rmin)
The a length of basis of the arc at the above peripheral speed tried to achieve and Rctr, can obtain hole in a circumferential direction
One end of bore and the mean value on the filter by the time needed for certain point on circumference for the other end.
In addition, the filtration either in a filter, all same hole being configured equably as the present embodiment
It in device, or is configured with in a filter in the filter in the different hole such as shape, size, can be by obtaining each
The length of camber line in hole and the peripheral speed at position (distance of distance center of rotation) place in hole, obtain each hole and move respectively
From hole camber line length (length of bore in a circumferential direction) needed for time, and obtain the average of described time
Value, obtain one end of hole bore in a circumferential direction and the other end by the time needed for certain point on circumference in mistake
Mean value on filter.
Figure 12 is the figure of the relation with capture rate for the smoke exhaust ventilator mesoporous mean transit time tx representing the present invention.On figure
Curve each represent and measured by making the filter in various aperture rotate with the revolution of various time per units
In the case of aperture averaging pass through time and capture rate.For the curve on figure, draw in the way of making R square value become maximum
Regression curve (quadratic polynomial regression curve, R2=0.97).Accordingly, with regard to the best capture rate exceeding existing filter
The filter of i.e. 70%, if used in view of the recurrence at the dotted line by the error of temporal about 3% for the aperture averaging
Curve, then aperture averaging is 3.2 × 10 by the time-4Second, and preferably using the regression curve of solid line, aperture averaging passes through
Time is 2.7 × 10-4About Miao.Therefore, if aperture averaging is less than or equal to 3.2 × 10 by the time-4Second, then can provide
The high smoke exhaust ventilator of oil capture rate.
Know according to (1) formula, if if the revolution N per second of filter accelerates or the diameter DA in hole reduces, then aperture
Mean transit time tx diminishes.Therefore, the smoke exhaust ventilator of the present invention can be with the aperture of the rotating speed of filter and filter for ginseng
Number, adjusts aperture mean transit time.Regression curve is because decline to the right, so in order to make capture rate good, permissible
Reduce aperture averaging and pass through the time.Therefore, in order to make capture rate be about 80%, aperture averaging can be arranged to by the time
1.8×10-4About Miao, preferably can be configured to 1.5 × 10-4About Miao.In addition, in order to make capture rate be about 90%, can
To be arranged to 0.98 × 10-4About Miao, preferably can be configured to 8.0 × 10-5Second.
Table 1 represents the aperture (mm) of filter in the present embodiment and the relation of rotating speed (rpm) and capture rate.It with aperture is
The these four type of 0.75mm, 1mm, 1.5mm, 2mm has carried out the measurement of capture rate.Rotating speed at filter is the situation of 0rpm
Under, no matter which kind of aperture, best capture rate that is 70% of below existing filter, it is known that catching of the filter not rotated
Obtain rate not high.
On the other hand, if making filter rotate with 1000rpm, even if then in the filtration of the minimum aperture 2mm of capture rate
In device, capture rate is also 77%, exceedes the capture rate of existing best filter.In addition, with aperture be reduced to 1.5mm,
1mm, 0.75mm, capture rate is further increased to the 80%th, the 86%th, 88%.If in addition, the rotating speed of filter is 1500rpm, then
As aperture is reduced to 2mm, 1.5mm, 1mm, 0.75mm, it is the 84%th, the 86%th, the 91%th, 93% that capture rate steps up.In addition,
If the rotating speed of filter is 2000rpm, then as aperture is reduced to 2mm, 1.5mm, 1mm, the 90%th, the 88%th, capture rate become
90%.Therefore, the smoke exhaust ventilator of the present invention makes filter rotate by making fan produce air stream, captures and comprises
Aerial oil divides.In addition we know, if if increasing revolution or the reduction aperture of the time per unit of filter, then
High oily capture rate can be obtained.
[table 1]
As described above, the aperture averaging exceeding capture rate 70% is 3.2 × 10 by the time-4Second, in addition, described aperture is put down
All determined by the combination in the aperture of filter and rotating speed by the time.Then, the situation in following aperture and the combination of rotating speed
Under, aperture averaging is 3.2 × 10-4Second, it is possible to achieve capture rate 70%.That is, exist
Aperture, i.e. hole bore in a circumferential direction is less than or equal to 0.75mm and the rotating speed of filter is more than or equal to
230rpm, or
Aperture is less than or equal to 1.00mm and the rotating speed of filter is more than or equal to 310rpm, or
Aperture is less than or equal to 1.50mm and the rotating speed of filter is more than or equal to 460rpm, or
Aperture is less than or equal to 2.00mm and the rotating speed of filter is more than or equal to 620rpm, or
In the case that aperture is more than or equal to 1500rpm less than or equal to the rotating speed of 5.00mm and filter, it is provided that oil
The high smoke exhaust ventilator of capture rate.
In addition, it is further preferred that the aperture averaging exceeding capture rate 70% is 2.7 × 10 by the time-4Second.Then same
Ground,
Aperture, i.e. hole bore in a circumferential direction is less than or equal to 0.75mm and the rotating speed of filter is more than or equal to
270rpm, or
Aperture is less than or equal to 1.00mm and the rotating speed of filter is more than or equal to 360rpm, or
Aperture is less than or equal to 1.50mm and the rotating speed of filter is more than or equal to 540rpm, or
Aperture is less than or equal to 2.00mm and the rotating speed of filter is more than or equal to 720rpm, or
In the case that aperture is more than or equal to 1800rpm less than or equal to the rotating speed of 5.00mm and filter, it is provided that oil
The high smoke exhaust ventilator of capture rate.
In addition, when oil divides surface (not the having the part in hole 11) of the upstream side clashing into filter, the major part of oil point
Splash to the outer peripheral edge direction of filter, but part attachment is on said surface.If the rotating speed of filter accelerates, then temporarily
The oil being attached on filter surfaces divides the effect against centrifugal force to fly to outer peripheral edge direction.Its result, the smoke pumping of the present invention
Machine adheres on the filter and the oil that remains divides minimizing, can mitigate the labour that filter self cleans accordingly.
Figure 13 is filter in the smoke exhaust ventilator of the slotted filter device in order to obtain the present embodiment and the existing type of use
The attachment point in the components downstream such as fan, pipeline of capture rate and oil relation test in the test structure chart that uses.Profit
The different this point of capture rate by the aperture difference of the filter of the present embodiment is different in order to confirm the capture rate according to filter
And the oily attachment state in components downstream, carry out following test.
Method of testing is as follows.The filter etc. possessing the present invention is set at 800mm above the heating plate of temperature-controllable
Smoke exhaust ventilator.Stainless steel cylinder is placed in the heating plate being heated to 245 DEG C, divides with 2.5g/ to described stainless steel cylinder from pump
Clock drips oil dripping water with 8g/ minute.Testing time is 10 minutes.In addition, the rotating speed of filter is 1500rpm.
Table 2 represents the result of this test.According to this test, at the slotted filter using the smoke exhaust ventilator as existing type
In the smoke exhaust ventilator of device, the oil capturing 50% on the filter divides, and has the oil of 23% to divide and be attached in components downstream.Remaining
The oil of 27% divides together with air externally discharged.On the other hand, the taking out of the filter possessing aperture 2.0mm at the present embodiment
In lampblack absorber, the oil capturing 83% on the filter divides, and has the oil of 7% to divide and is attached in components downstream.In addition, possessing aperture
In the smoke exhaust ventilator of the filter of 1.5mm, the oil capturing 83% on the filter divides, and has the oil of 2% to divide and is attached to components downstream
On.In addition, in possessing the smoke exhaust ventilator of filter of aperture 1.0mm, the oil capturing 87% on the filter divides, and makes us frightened
Be surprised is the attachment not observing oil point in components downstream.
According to described test, compared with the capture rate of the smoke exhaust ventilator with existing type, in the smoke exhaust ventilator of the present embodiment,
The capture rate of filter is up to 83% or higher significantly.It is as a result, it is possible to significantly inhibit and want worker employed in a plant nursery at aspects such as cleaning/cleanings
The oil of husband divides the attachment in components downstream.If it is considered that the capture rate of existing known smoke exhaust ventilator is also most preferably just 70%,
No matter how varying aperture all has 83% or higher capture rate to the smoke exhaust ventilator of the present invention then using in this test, can
With the smoke exhaust ventilator saying the present invention, there is high capture rate.Therefore, the smoke exhaust ventilator of the present invention is because oil point is almost without attached
In the components downstream of the filter in air flow circuit, it is possible to mitigate the downstream of cleaning/cleaned filter significantly
The burden of part.
