2. Description of the Related Art For hulling work in farming work, individual farmers have traditionally owned their own hullers, or local farmers jointly invested to construct a large hulling facility. Was being done. At the time of hulling work using a general hulling machine, a method is used in which air is sent under pressure to efficiently separate rice and hulls and only the light hulls are blown off by the wind force. The blown-off rice husk is discharged along the exhaust pipe connected to the huller, and the rice husk is selectively dropped from the exhaust air by a collector provided in the middle of the exhaust pipe.
Only the exhaust air was blown away by a further extended exhaust pipe.

A general huller having a general huller installed will be described below with reference to the schematic view of FIG. 8 schematically showing the installation state of the conventional huller. The sliding machine 1 shown in the figure is
An exhaust pipe 2 for pumping and discharging the chaff after hulling by wind is provided, and the exhaust pipe 2 is configured by connecting a plurality of pipes. A rice husk collecting device 5 that selectively separates the husks 3 and the exhaust air 4 and drops only the rice husks 3 is provided in the middle of the exhaust pipe 2, and each of the rice husk collecting devices 5 discharges the exhaust air. Are arranged along the extension direction of the pipe 2,
The rice husks 3 are separated and collected from the exhaust air 4 by, for example, obliquely installing an air-permeable metal net-like body in the middle empty space.

Each of the rice husk collecting devices 5 is provided with rice husk collecting branch pipes 7 and 8 which open downward, and these rice husk collecting branch pipes 7 and 8 collect the rice husks 3, respectively. The breathable bags 9 and 10 are detachably attached, and when full, they are replaced with new breathable bags. In this conventional hulling work, the exhaust air 4 after separating and collecting the rice husks 3 in the process of passing through the exhaust air pipe 2 is normally used as it is from the end of the exhaust pipe 2 further extended from the rice husk collecting device 5. It is common to discharge it. Therefore, the exhaust air 4 containing the fine dust 14 (small pieces of rice husks, rice bran, etc.) is continuously discharged from the exhaust air outlet 11 at the end of the exhaust pipe 2 for a long time, and is directly discharged into the workplace. If this happens, the interior of the room will be filled with dust 14 and the working environment will be deteriorated. Therefore, for example, the wall surface 13 of the workplace 12 is guided to the outside,
The device is designed so that the exhaust air 4 is discharged to the outside.

However, the exhaust air 4 including the dust 14 emitted to the outside causes the air to scatter outdoors and pollute the area. Especially, in a farmhouse near the urban area, which has a residential area or a shopping area nearby, In the rice harvest season, in order to prevent complaints from those neighbors, in some cases, the wind must be stopped in the work area, and the worker must accept the dusty work. The situation is still continuing. As means for removing the dust 14 from the exhaust air 4, for example, a mesh bag body that does not allow dust to pass through or a means for installing a dust filter used in other industrial fields at the exhaust outlet 11 are also considered. However, they deteriorate the flow of the exhaust air 4 at the end of the exhaust pipe,
The hulling machine 1 is subject to atmospheric pressure load and interferes with the normal operation of the hulling machine 1, which makes it impossible to employ dust removing means in the hulling machine 1.

Therefore, other means for preventing resistance to the hulling machine, for example, using a liquid such as a shower curtain at the end of the exhaust pipe or a sprayer,
There have been repeated attempts to separate the dust 14 from the exhaust air by attaching the dust 14 in the exhaust air 4 to a water stream that obstructs the air or fine water droplets flying in the air, but it is extremely fine and extremely small. The light dust is damaged by the surface tension of the liquid, and even if the surface adheres, it is not taken in, so most of the dust 14 except for a part of it falls on the surface of the water in the falling liquid stopper. It will be in a floating state,
After being separated, the exhausted air soars into the air again,
It has been confirmed that the known dust removing means employed in these other fields are not suitable as the dust removing means for the hulling work because they result in scattering around.

The inventor of the present application, as a person who belongs to a manufacturer of rice husk recovery equipment, repeats the trial and error as described above over a long period of time. As a result, we finally succeeded in finding the most economical means of water, and in some cases, very innovative means of removing dust in the blast air, which requires no power, and The present invention has succeeded in realizing a dust removing device that can reliably and efficiently realize dust removing means.Hereinafter, as a result, the dust removing method in the exhaust air of the present invention and The dust removing device having a novel configuration that is indispensable for implementation will be described in detail.

[0008]

Even if it is an exhaust pipe, it is possible to use the dust removing method and the dust removing device in the exhaust air, and clean the dust generated by the plant fiber processing such as rag stitching and no weaving. It may be for doing.

Even if the rotating body is provided with a drive source and is forcibly driven to rotate, it is possible to apply a centrifugal force to the dust-absorbing liquid so that the dust-absorbing liquid is scattered and atomized in the body of the body.

The dust-absorbing liquid may be any liquid that adsorbs or takes in dust, and even if it is vaporized steam or steam, it will be liquefied due to a decrease in temperature after adsorbing dust. It can be used as long as it has high fluidity by increasing the water temperature, or a liquid containing a surfactant can be used to enhance the adsorptivity to dust or contain oil. It may be one having an increased adhesiveness and an enhanced effect of taking dust into the liquid.

[0024]

[Operation] A method for removing dust in the exhaust air of the present invention having the above-described configuration, and a dust removing device 20 therefor
Is, for example, a function that removes dust from exhaust air containing dust discharged through the exhaust pipe of the huller 1 shown in FIG. 5 and allows it to be discharged into the room as clean exhaust air. In the case of the example of the machine 1, the rice husks 3 placed in the middle thereof are first separated and collected by the rice husks 3 carried by the exhausted air 4, and only the exhausted air 4 containing the fine dust 14 is separated. The air is blown before the collection device 5.

The exhaust air 4 containing the dust 14 is discharged from the exhaust port 11 of the exhaust pipe 2 in the direction indicated by the white arrow C, as shown in the front sectional view of FIG. Be guided to. The sprinkler nozzle 23 is provided at the destination where the exhaust air C is discharged.
A rotator 24, to which tap water as a dust absorbing liquid is supplied from a nozzle of, is rotatably arranged, and exhausted air C is blown onto the surface of the rotator 24 to be received by the blade 24a. With the wind pressure of the exhaust air C, it is in a state of rotating at a substantially constant speed. At the same time, dust 1 contained in the exhaust air C
No. 4 collides with the surface of the conical rotating body 24, and while moving downward along the conical wall surface, part of the dust absorbing liquid that is supplied to the surface and diffuses evenly into the surroundings flows down. While adhering or mixing with each other, the remainder flows downward along the slope or becomes a turbulent air flow in the space between the rotating body 24 and the body main body 21 and swirls, and is retained for a while and then guided downward. It becomes a state.

On the other hand, the tap water supplied from above the rotating body 24 reaches the peripheral edge along the surface of the rotating body 24, and then a part of dust is generated by the centrifugal force of the rotating body 24 rotating in a certain direction. With 14 included, it is blown out in the outer peripheral direction, strongly collides with the inner peripheral wall of the body 21 and shatters inward,
It is extremely complicated, such as returning to the rotating body 24 again, hitting water droplets that are sequentially spun off by centrifugal force in the middle and further crushing, or colliding with these water droplets and colliding with the inner peripheral wall surface of the body again and crushing. Body 2
In the vicinity of the space that is communicated downwards, which is regulated by the inner peripheral wall 1 and the periphery of the rotating body 24, the dusts 14 that pass through the space and pass downwards have complicated shapes, water flows and water droplets existing in motion, It cannot be scratched between the sprays and is attached or taken in by the dust adsorbing liquid and is almost completely separated from the exhaust air.

By setting the inner diameter a of the air exhaust port 11 to 200 mm and the gap dimension S1 between the outer peripheral edge of the rotor 24 and the inner peripheral wall surface of the body 21 to be 120 mm on one side,
It is possible to prevent the generation of load due to the air resistance of the exhaust air, and to keep the operation of the hulling machine 1 in a good condition. This is a fact that the inventor of the present invention has been able to confirm by conducting many trial experiments, and keep the relationship of a ≦ 2S1 (or a ≦ S1 + S1 when the left and right S1 dimensions are different from each other). As a result, the air resistance can be reduced and good exhaust can be achieved. Therefore, the dimensions are set as described above. That is, when the condition of a ≦ 2S1 is not satisfied, the discharge of exhaust air is not stable, the pressure in the exhaust pipe 2 increases, and good operation of the huller 1 cannot be ensured. When the inner diameter a of the air outlet 11 is set to 200 mm, it is desirable that the gap dimension S1 between the outer diameter edge portion of the rotating body 24 and the inner peripheral wall surface of the body portion 21 is set to 100 mm or more on one side. It is a thing.

Further, it has been clarified by experiments that the air flow becomes stable by keeping the relation between the maximum inner wall diameter S of the body portion 21 and the inner diameter a of the exhaust port 11 such that S ≧ 2a. ing. The liquid to which the dust 14 is attached or taken in is dropped directly into the water receiving portion 25 as shown by an arrow E, or the inclined edge portion 21a of the body portion 21 inclined 27 degrees toward the inside. Is oriented along the inner wall of the arrow in the direction indicated by the white arrow F, and the lower center line G
The air pressures cancel each other out in the space indicated by, and after that, the liquid that has adhered the dust 14 or has taken in is dropped into the water receiving portion 25 and drained as shown by the white arrow H. Is configured.

10c from the bottom edge of the body 21
By bending the inclined edge portion 21a of m or more inward at the bending angle B between 25 degrees and 30 degrees, it is possible to perform the best offset of the wind pressure. If it comes off, the air flow may be disturbed and liquid water may be scattered to the outside.

On the other hand, in the case shown in the front cross-sectional view of the dust removing device 20 of FIG. 6 and the plan view of the dust removing device 20 of FIG. 7, the air outlet 11 is connected to the side wall of the body 21 from the horizontal direction. The exhaust air sent under pressure is configured to be blown to one side of the rotating body 24, which is slightly off the center of the upper side of the rotating body 24, as indicated by the white arrow C. The exhaust air blown on the rotating body 24 in this manner descends toward the inclined edge portion 21a while rotating in a spiral shape around the rotating body 24 along the inner wall surface of the body portion main body 21. The rotating body 24 blows off exhaust air around the blades 24a, 24
Rotational force is generated in one direction as indicated by the receiving arrow on a, ...
It is rotated at a constant speed.

Water as a dust absorbing liquid is supplied from above from the water spray nozzle 23 to the exhaust air swirling spirally,
Similar to the first embodiment, the dust 14 adheres to or is taken into the interior, falls on the water receiving portion 25, and is drained.

[0032]

[Effects] As described above, the method of removing dust in the exhaust air according to the present invention diffuses and scatters in the body of the body by supplying the dust absorbing liquid to the surface of the rotating body rotating in the exhaust air. Liquid that atomized into droplets due to collision of droplets,
It is based on an extremely epoch-making technical idea that applies the principle that it is reliably attached to the dust in the exhaust air and is taken into the liquid. The slanted edge of the body body that is squeezed in the direction guides, the dust absorbing liquid collides with each other in the lower space of the body body, the wind forces are canceled, and the droplets that lost the wind force continue to move downward. Since the air that has fallen into the air and lost the wind force is discharged to the surrounding area, it is possible to reliably remove the dust in the exhaust air without the need for a filter, etc., and to provide an extremely ideal dust removal method. I was able to.

Further, since the dust removing device used in the dust removing method has a structure in which exhaust air containing dust absorbing liquid is caused to collide with each other by the inclined surface of the inclined edge portion of the body of the body, the liquid and air are separated from each other. The structure for separating the filter etc. which was required in the past is not necessary at all, and it is extremely rational, and not only can the manufacturing cost of the entire device be reduced, but the maintenance that is usually required is also dust absorption. The economical ripple effect is extremely high, such that it can be used by extremely simple maintenance and inspection, such as only liquid processing.

Further, the dust removing device 2 shown in the first embodiment
In 0, since the inclined edge portion 21a of the body portion 21 is bent inward within the range of 25 degrees to 30 degrees, the exhaust air containing the dust absorbing liquid is as shown by the arrow F. It is possible to smoothly guide the mutual wind pressures to the space G that is efficiently canceled, and it is possible to ensure stable operation without generating unnecessary air resistance or the like. Further, by setting the inner diameter of the air exhaust port 11 to a and the relationship between the outer edge of the rotating body and the gap S1 on one side between the inner wall surface of the body of the body to be a ≦ 2S1, a sufficient exhaust air flow path can be obtained. It becomes possible to secure,
Air resistance can be reduced. By providing a rough ventilation body that surrounds the space G on the lower side of the body portion where the exhaust air collides, the influence of the inflow of air from the outside of the device is prevented, and the stable exhaust air pressure is provided. It is possible to offset. Moreover, the coarse ventilator can prevent clogging of dust.

As described above, the method for removing dust in the exhaust gas of the present invention is based on a very original technical idea, and its implementation is easy, and a reliable dust removal effect can be expected. It is an excellent dust removal method, and also a dust removal device for realizing it can be provided easily at a relatively low cost and can be spread over a wide range of fields.
It does not require a space for accumulating dust and can prevent dust from scattering to the surroundings.It is effective for space saving and hygienic environmental conservation in the workplace. It is expected that it will be greatly welcomed in the future as a dust removal measure for wood processing plants.
