Description

The present invention relates to a space disinfection device, and more particularly to a space disinfection device that releases air containing finely divided disinfectant particles into a space in a room to disinfect an object in the room.

In recent years, in livestock facilities, measures against the transmission of infectious diseases to livestock have been emphasized. Therefore, attempts have been made to disinfect these when people or the like enter them to prevent the causative bacteria from being brought in from the outside. For example, in indoor livestock facilities such as barns and poultry houses, disinfection is performed using a step-in disinfection tank that disinfects boots by immersing them in a disinfectant solution such as an inverted soap solution.

On the other hand, there are cases where the causative bacteria are carried not only on shoes but also on clothes. Therefore, when entering an indoor livestock facility, it is preferable that clothes and the like can also be disinfected. As a device capable of such disinfection, for example, a space disinfection device that releases air containing disinfectant liquid particles (hereinafter, also simply referred to as mixed air) into the air is known (for example, Patent Document 1).

It is a perspective view of the air disinfection device of this embodiment. It is sectional drawing in the Y-axis direction of the air disinfection apparatus of this embodiment. It is a schematic diagram which shows an example of the arrangement of a nozzle.

Next, one embodiment of the present invention will be described.
The present embodiment relates to a space disinfection device that discharges air containing finely divided disinfectant particles into a space in the room and disinfects an object in the room, and introduces an introduction port and an introduction port for introducing air sent from a blower mechanism into the space. It has a housing having a discharge port that discharges air containing finely divided disinfectant particles to the outside, and a donut-shaped shape formed in the housing and having a cross section along a direction perpendicular to the direction of air flow. The air passage, the nozzle that injects the disinfectant liquid into the air passage and contains the disinfectant liquid particles in the flowing air, and the mixed air that circulates the air containing the finely divided disinfectant liquid particles that have passed through the air passage to the outlet. It is equipped with a flow passage.

FIG. 1 is a perspective view of the space disinfection device of the present embodiment. Further, FIG. 2 is a cross-sectional view of the space disinfection device of the present embodiment along the Y-axis direction. In FIGS. 1 and 2, the dashed arrow indicates the flow of air.
The housing 10 has a recovery tank 11 and a tubular body 12 stacked on one end of the recovery tank 11. The recovery tank 11 and the tubular body 12 communicate with each other so that air can move inside them. Further, the recovery tank 11 has a protrusion 113 at the other end on the recovery tank 11, and a discharge port 16 is formed at the upper end thereof.

In the recovery tank 11, a predetermined amount of water is stored inside the recovery tank 11. The amount of water stored is not particularly limited and can be appropriately set, but in the present embodiment, it is set so as to have a certain space above the stored water. Therefore, for example, the recovery tank 11 may be provided with a drain port 115 in order to prevent the amount of water from exceeding a predetermined amount.
In the present embodiment, air can move from the tubular body 12 to the discharge port 16 through the space above the stored water (the space corresponds to the mixed air flow passage).

As described above, the mixed air flow passage 41 is formed in the recovery tank 11 between the water and the inner wall of the upper part of the recovery tank.
Here, in the present embodiment, the mixed air flow passage 41 has a width in a direction orthogonal to the first flow area 43 and the direction in which the air containing the finely divided disinfectant particles flows (in the present embodiment). It has a second distribution area 45 in which the distance between the upper inner wall of the recovery tank 11 and the liquid level) is shorter than that of the first distribution area.
The number of second distribution areas and the like is not particularly limited and can be set as appropriate. For example, as shown in FIG. 2, a plurality of second distribution areas may be provided with the first distribution area in between. ..

From the discharge port 16 formed in the protrusion 113, air containing particles of the disinfectant liquid that has passed through the mixed air flow passage 41 is discharged to the outside of the space disinfection device 1 of the present embodiment. In the present embodiment, the diameter of the discharge port 16 is set to be larger than that of the mixed air flow passage 41.

At the end of the tubular body 12 opposite to the side connected to the recovery tank 11, an introduction port 18 for introducing the air sent from the blower mechanism 21 (fan) into the housing 10 is provided. There is. In the present embodiment, the fan 21 is provided at the introduction port 18, and the rotation of the fan 21 introduces air into the housing 10. Further, in the present embodiment, the filter 22 is arranged at the introduction port 18 in order to prevent the suspended matter or the like outside the device 1 from being introduced into the housing 10 together with the air.

In the tubular body 12, the air passage wall forming body 25 is arranged inside the tubular body 12. In its appearance, the air passage wall forming body 25 has a columnar region and a conical shape that is located closer to the introduction port 18 than the columnar region and is reduced in diameter toward the introduction port 18. Has an area of.
The air duct wall forming body 25 is arranged so that the introduced air flows into the tubular body 12 through between the inner wall side portion of the tubular body 12 and the outer wall side portion of the air duct wall forming body 25. Will be done. Therefore, a donut-shaped air passage 27 is formed in the tubular body 12 in a cross section along a direction orthogonal to the air flow direction (Y-axis direction). Further, since the air passage wall forming body 25 is composed of a conical region and a columnar region as described above, in the air passage 27, as the air passes from the start position of the air passage 27 toward the air flow direction. The width becomes narrower, and then the width becomes constant in the region where the air duct wall forming body 25 is columnar.

On the side wall of the tubular body 12, a nozzle 23 for containing disinfectant particles in the air flowing inside the tubular body 12 is arranged.
The nozzle 23 is arranged so that the axial direction is along the Y-axis direction. Further, in the present embodiment, two groups (a total of eight) are arranged, with the case where four nozzles 23 are arranged on the same plane at substantially equal intervals as one group. As can be understood from the cross-sectional view taken along the line AA (FIG. 1) of the tubular body 12 shown as FIG. 3, these nozzles 23 are arranged in a staggered manner so that the nozzles 23 do not overlap each other.
The disinfectant solution supplied to the nozzle 23 and the disinfectant solution supply mechanism are not particularly limited and can be appropriately set by those skilled in the art. Examples of the disinfectant solution include hypochlorous acid water. Further, for example, the disinfectant solution may be supplied to the nozzle 23 from the disinfectant solution storage unit 60 provided separately from the space disinfection device 1 of the present embodiment via a supply mechanism such as a pump 62. it can.

Next, the generation and release of the mixed air using the space disinfection device 1 of the present embodiment will be described.
First, the pump 62 is driven to inject the disinfectant solution from the nozzle 23 toward the air passage 27, and the fan 21 is rotated to introduce air into the tubular body 12 from the introduction port 18. At this time, by introducing the air into the tubular body 12 which is narrower than the external space, the flow velocity of the air is increased.
The flow velocity of the air introduced into the housing when the mixed air is generated is not particularly limited, and can be appropriately set according to the size of the device, the place where the device is installed, and the like. For example, the wind speed is 0. The fan 21 may be rotated so that air is introduced at 5 to 50 m / sec.

The air introduced into the tubular body 12 moves in the air passage 27 formed between the outer wall side portion of the air passage wall forming body 25 and the inner wall side portion of the tubular body 12 in the tubular body 12. In the air passage 27, the disinfectant liquid ejected from the nozzle 23 and the air moving through the air passage 27 come into contact with each other, and the disinfectant liquid particles are present in the flowing air (generation of mixed air).
At this time, among the disinfectant liquids ejected from the nozzle 23, those which are in the form of particles by the injection will be present in the air flowing as they are. Further, when the sprayed disinfectant collides with the outer wall side portion of the air passage wall forming body 25 and the disinfectant is scattered, further disinfectant particles are generated, and the disinfectant particles are also carried by the circulating air.
The disinfectant solution that is not in the form of particles falls into the water stored in the recovery tank 11 that connects the outer wall of the air passage wall forming body 25 and communicates with the tubular body 12, for example.

The mixed air of air and disinfectant particles generated in the air passage 27 moves from the air passage 27 to the recovery tank 11. Subsequently, the mixed air moves in the mixed air flow passage 41, which is the upper space in the recovery tank 11. At this time, there is a speed difference in the movement of the mixed air between the first region 43 and the second region 45 (in the second region, the wind speed is faster than that in the first region).
While the mixed air passes through the mixed air flow passage 41, the particles that are not sufficiently refined fall into the water stored in the recovery tank 11. Further, by providing the first region and the second region as described above, it is possible to more reliably refine the disinfectant liquid particles in the mixed air discharged from the discharge port 16 (mixed air flow passage (particularly, the first region). The slower wind speed after passing through region 2) makes it easier for particles that are not sufficiently miniaturized to fall into water).

The mixed air that has moved through the mixed air flow passage 41 is discharged from the discharge port 16 to the outside of the housing 10. At this time, the mixed air is released into a wider space and expands, and the spaces between the fine particles are widened, so that the disinfectant liquid particles are further refined.

The space disinfection device 1 of the present embodiment can be used, for example, in a space indoors, and can disinfect an object in the space.
Specifically, one room is provided as a disinfection room at the entrance of an indoor livestock facility such as a barn or a poultry house, and the space disinfection device 1 of the present embodiment can be installed in the disinfection room. The space disinfection device 1 of the present embodiment can disinfect, for example, the clothes of a person who enters the livestock facility. Further, the object to be disinfected may be the room itself or the articles provided.
At this time, according to the space disinfection device 1 of the present embodiment, it is possible to disinfect by releasing finer particles of the disinfectant liquid, so that disinfection can be performed in more detail. Therefore, it can contribute to more reliable prevention of infectious diseases.

Although the space disinfection device of the present embodiment has been described above, the present invention is not limited to this, and other embodiments can be used.
For example, in the present embodiment, eight nozzles are arranged in a staggered pattern as described above, but the present invention is not limited to this, and other arrangements and numbers may be used. On the other hand, by arranging them in a staggered pattern as described above, more nozzles can be arranged in the space disinfection device of the present embodiment.
Further, in the present embodiment, the air duct wall forming body is configured to have a columnar region and a conical region, but the present invention is not limited to this, and may have other shapes. For example, a columnar air duct wall forming body can be arranged in a tubular body.
Further, in the space disinfection device of the present embodiment, as described above, the supply of the disinfectant solution to the nozzle is not particularly limited and can be appropriately set by those skilled in the art. For example, the disinfectant solution may be stored in the disinfectant solution recovery tank 11 and the disinfectant solution may be supplied to the nozzle 23.
