Description

A device for collecting hazardous substances in the air {COLLECTING DEVICE FOR HARMFUL MATERIAL IN AIR}

It relates to a device that collects substances existing in the air.

Respiratory viral infection is one of the most common diseases that occur in humans, causing sequelae in infants, the elderly, and patients with reduced cardiopulmonary or immune function, leading to death in severe cases. In addition to influenza virus, respiratory viruses include adenovirus, parainfluenza virus (PIV), respiratory syncytial virus (RSV), rhinovirus, and severe acute respiratory syndrome (SARS), which are pathogens that commonly cause colds. Infections caused by new viruses such as viruses, avian influenza virus, and Middle East respiratory syndrome coronavirus (MERS-CoV) have become prevalent around the world, and the spread of the COVID-19 virus around the world threatens the health and lives of many people. Not only that, it is amplifying social and economic risks.

Since there is no clear solution other than prevention in the early stages of an epidemic, it is necessary to monitor various pathogens in the air in real time to detect and quarantine them early to prevent the spread.

However, because pathogens in the air exist in extremely small concentrations, they are very difficult to detect. Therefore, a large amount of air must be collected over a long period of time, and if the amount of sample collected is not sufficient, errors in analysis may occur in which it is not detected even though it actually exists.

Representative air collection technologies include cyclones and electrostatic dust collection, but most of them have the disadvantages that the amount of air that can be processed per unit time is less than several tens of LPM (liter per minute), the noise is high, and the equipment for driving the collector is large and expensive.

The purpose of the present invention is to provide a capture device capable of capturing high concentrations of harmful substances such as viruses, bacteria, mold, and fine dust that exist in trace concentrations in the air.

The present invention includes a chamber equipped with a fan for sucking air; and a liquid collection tank accommodated in the chamber and configured to collect hazardous substances in the air by colliding air sucked into the chamber with a liquid collection medium.

In one embodiment, the liquid collection tank includes a container capable of containing a liquid collection medium; And it may include a collector accommodated in a container. The collector may have a plurality of pillars, and may be configured to move up and down or rotate within the container during operation so that the plurality of pillars are at least partially exposed to the outside of the collection medium.

In one embodiment, the collecting body includes: a circular disk disposed at a predetermined angle with respect to the surface of the collecting medium; And it may further include a rotation shaft rotatably connecting the disk to the container. In addition, the plurality of pillars are provided on the upper surface of the disk, and during operation, a film of the collecting medium is formed on the pillars exposed to the outside of the collecting medium among the plurality of pillars, which may collide with the air sucked into the chamber.

In one embodiment, the bottom surface of the container may be inclined at a predetermined angle, the same as that of the disk.

In one embodiment, a hazardous substance collection device includes: a drive motor for rotating the collection body; And it may further include a control panel mounted outside the chamber. The control panel includes a processor for controlling the drive motor, and the processor can control the collector to rotate at a predetermined rotation speed based on at least one of the temperature and humidity of the environment surrounding the chamber.

In one embodiment, the processor may additionally control the rotation direction of the collector.

In one embodiment, a hazardous substance collection device includes a drive motor for moving the collector up and down; And it may further include a control panel mounted outside the chamber. And the control panel includes a processor for controlling the drive motor, and the processor can control the drive motor so that the collector moves up and down at a predetermined cycle.

In one embodiment, the processor may further control the driving motor so that the collection object moves inside the collection medium after being exposed to the outside of the collection medium for a predetermined time.

In one embodiment, the plurality of pillars may be arranged to be spaced apart from each other at intervals of 0.2 mm to 10 mm.

In one embodiment, the plurality of pillars may have a cylindrical shape with a diameter of 0.1 mm to 5 mm.

As an example, the height may be 0.5 cm to 5 cm.

According to the present invention, hazardous substances existing in trace amounts in the air can be collected at high concentrations in a short period of time, thereby shortening the time for diagnosis and analysis of hazardous substances and securing sufficient samples.

In addition, according to the present invention, unlike the conventional inertial collision type cyclone liquid collector, a pump is not used, so a low-noise, low-cost collection device can be provided, continuous operation is possible, and miniaturization is possible. In addition, according to the present invention, it is possible to collect fine substances of less than 1㎛, which are hardly captured in conventional inertial impact cyclone liquid collectors, at high concentrations.

In addition, according to the present invention, there is an effect of collecting fine substances more safely at a lower cost than a conventional electrostatic precipitator using an expensive high charge.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the attached drawings. First, when adding reference signs to components in each drawing, it should be noted that the same components are given the same reference numerals as much as possible even if they are shown in different drawings. Additionally, if it is judged that it may obscure the gist of the present invention, the detailed description will be omitted. In addition, embodiments of the present invention will be described below, but of course, the technical idea of the present invention is not limited or limited thereto and can be practiced by those skilled in the art.

1 is a side view of a hazardous substance collection device according to an embodiment of the present invention. The hazardous substance collection device 100 according to an embodiment of the present invention includes a chamber 110, a fan 120, a control panel 130, a drive motor 140, and a liquid collection tank 200. Figure 2 is a perspective view of the liquid collection tank 200, and Figure 3 is a cross-sectional view taken along line I-I of Figure 2.

The chamber 110 sucks air into the chamber, and inertially collides the sucked air into the liquid collection tank 200 to form a space for collecting harmful substances in the air. The chamber 110 has an air intake port 111 formed at the top, and a fan 120 is mounted on the air intake port 111. Additionally, vents (not shown) may be further formed in the chamber 110. The chamber 110 may be made of PLA (Poly Lactic Acid). Chamber 110 can be manufactured with a 3D printer.

The fan 120 has a flow rate sufficient to introduce a large amount of air from the outside to collect hazardous substances in high concentration in a short period of time. In one embodiment, the fan 120 may have a diameter of 5 cm to 30 cm and a flow rate of 100 LPM to 5,000 LPM (L/min). For example, fan 120 may have a diameter of 15 cm and a flow rate of 2,650 LPM. The size of the air intake port 111 of the chamber 110 is determined in accordance with the size of the fan 120.

The control panel 130 is electrically connected to the fan 120 and includes a processor (not shown) to control the rotation speed of the fan 120. Additionally, the control panel 130 may be further equipped with a display (not shown) that displays the rotation speed of the fan 120 and buttons (not shown) for power control and rotation speed control of the fan 120. Additionally, the processor of the control panel 130 is electrically connected to the collector 230 and controls the operation of the collector 230. This will be described later.

In this embodiment, the control panel 130 is described as being mounted outside the chamber 110, but the present invention is not limited to this. As another embodiment, the control panel may be implemented in the form of a terminal such as a personal computer, laptop, or smartphone installed with a program or app for controlling the collection device, and the fan 120 and the driving motor ( 140), so that the operation of each component can be controlled.

The drive motor 140 is connected to the drive gear 220 and rotates the drive gear 220, and thus the collector 230 engaged with the drive gear 220 rotates. The motor shaft of the drive motor 140 is connected to the shaft 221 of the drive gear 220. The drive motor 140 receives a control signal from the control panel 130 and rotates the drive gear 220 at a predetermined rotation speed.

The liquid collection tank 200 is stored in the chamber 110 and includes a container 210, a driving gear 220, and a collection body 230. The container 210 accommodates a liquid collection medium (e.g., triple distilled water) for collecting hazardous substances, and the collection medium 230 is arranged so that the collection medium 230 can be at least partially submerged in the collection medium. accept. In addition, a drive gear 220 engaged with the collector 230 is installed on the inner side wall of the container body 212, and the axis 221 of the drive gear 220 is a groove formed on the side wall of the container body 212 ( Connected to the drive motor 140 through 211).

The driving gear 220 includes a circular plate 223 on which a plurality of teeth 225 are formed on the outer circumference. Additionally, the driving gear 220 includes a shaft 221 extending from the center of the circular plate 223 to the driving motor 140. The circular plate 223 may be arranged parallel to the side wall of the container body 212.

The liquid collection tank 200 is located within the chamber 110 so that the upper part of the container body 212 is open toward the air intake port 111. The air sucked into the chamber 110 through the air intake port 111 may inertially collide with the surface of the collection medium contained in the container 210 of the liquid collection tank 200. In addition, the sucked air additionally inertially collides with the film of the collection medium formed on the surface of the collector 230 when the collector 230 provided in the liquid collection tank 200 rotates, causing harmful substances in the air to be released at a high concentration in a short period of time. The substance can be captured using a collection medium. This is explained in more detail below.

Figure 4 is a perspective view of the collector 230, and Figure 5 is an enlarged plan view of portion A of Figure 4. The collector 230 includes a circular disk 233 with a plurality of teeth 235 formed on its outer circumference. The plurality of teeth 235 of the collector 230 are engaged with the plurality of teeth 225 of the drive gear 220, and when the drive gear 220 rotates, the collector 230 is engaged with the drive gear 220. ) rotates at a predetermined rotation speed. When the collector 230 is disposed at an angle with respect to the surface of the collection medium contained in the container 210 as shown in FIG. 1, the drive gear 220 is arranged to engage with the highest-located tooth when the collector 230 rotates. do.

Additionally, the collector 230 includes a plurality of pillars 231 provided on the upper surface of the disk 233 to expand the surface area where the sucked air inertially collides with the collection medium. The pillar 231 may have a cylindrical shape, and the diameter (d) of the pillar 231 may be 0.1 mm to 5 mm and the height may be 0.5 cm to 5 cm. For example, the pillar 231 may have a diameter of 1 mm to 3 mm. The plurality of pillars 231 are arranged at intervals (G) from each other, and may be arranged at intervals (G) of 0.2 mm to 10 mm.

The plurality of pillars 231 may be arranged in a row along the imaginary line (L) when an imaginary line (L) is drawn radially outward from the center (C) of the disk 233. However, it is not limited to this, and any arrangement that allows the largest number of pillars 231 to be arranged on the disk 233 on the same plane may be used. Additionally, the plurality of pillars 231 may be arranged in a regular or irregular pattern that can maximize the surface area of the collecting medium that inertially collides with the intake air when the collecting body 230 rotates.

The disk 233 of the collector 230 may be disposed inclined at a predetermined angle with respect to the surface of the collection medium contained in the container 210. For example, the collector 230 may be inclined with respect to the surface of the collection medium at an angle of 1° to 90°. Since the disk 233 is tilted with respect to the surface of the collecting medium, the amount of collecting medium contained in the container 210 is adjusted so that at least a portion of the collecting medium 230 is exposed outside the collecting medium. can be rotated. When the collector 230 rotates, a film of the collection medium is formed on the plurality of pillars 231 exposed outside the collection medium, which may inertially collide with the air sucked into the chamber 110.

Figure 6 is a perspective view of the container 210. Referring to FIGS. 1, 3, and 6, the bottom surface 214 of the container body 212 of the container 210 is inclined at the same angle as the disk 233 of the collector 230. Since the bottom surface 214 of the container 210 is tilted in this way, the amount of collection medium required to at least partially submerge the tilted collector 230 is less compared to the case where the bottom surface of the container is not tilted. . For example, when the collecting body 230 is submerged in the collecting medium at least up to the center C, a smaller amount of collecting medium is required when the bottom surface of the container is tilted than when the bottom surface of the container is not tilted. Therefore, it is possible to collect harmful substances in the air at a higher concentration for the same amount of time.

As an additional and optional embodiment to further reduce the amount of collection medium, the inner wall of the container body 212 may be further provided with a plurality of step portions 217A and 217B. The plurality of step portions 217A and 217B extend radially inward from the inner wall of the container body 212 and extend longitudinally to the bottom surface 214 to further narrow the area of the bottom surface 214, thereby forming the container. The overall volume decreases.

The collector 230 further includes a rotating shaft fixing part 232 provided at the center C of the upper surface of the disk 233. The rotating shaft fixing part 232 is rotatably coupled to the bottom surface 214 of the container through the rotating shaft 219. A coupling hole 216 through which the rotating shaft 219 is coupled is formed on the bottom surface 214 of the container. The container 210 further includes a bearing 218 fixed within the coupling hole 216.

In order to minimize the materials required to manufacture the container, the container 210 may have an empty space below the bottom surface 214 spaced apart from the bottom surface of the chamber 100. In this case, a rotation shaft connection portion 215 for rotatably connecting the rotation shaft 219 to the container 210 may be formed to protrude downward from the bottom surface 214. The protruding length and width direction thickness of the rotating shaft connection portion 215 are determined to be the dimensions necessary for rigidity to rotatably support the rotating shaft 219. Referring to FIG. 3, the rotation axis 219 functions as the rotation axis of the collector 230 inclined at a predetermined angle, and is therefore disposed to be inclined with respect to the bottom surface of the chamber 110. The rotation shaft connection portion 215 of the container 210 is configured to firmly support both the inclined rotation shaft 219 and the collector 230 fixed to the rotation shaft 219 when the collector rotates. The coupling hole 216 extends from the bottom surface 214 to the rotation shaft connection portion 215. The lower part of the rotating shaft connecting portion 215 of the container 210 is spaced apart from the bottom surface of the chamber 110, so that vibration transmitted to the rotating shaft connecting portion 215 when the collector 230 rotates is transmitted to the chamber 110. It can be prevented.

In this embodiment, the drive motor 140 is connected to the drive gear 220, and the plurality of teeth 225 of the drive gear 220 and the plurality of teeth 235 of the collector 230 engage with each other to form the collector 230. ) is configured to rotate, but the present invention is not limited thereto. The drive shaft of the drive motor may be directly connected to the rotation shaft 219.

Each of the container 210, driving gear 220, and collector 230 can be made of ABS (acrylonitrile-butadiene-styrene copolymer) or PLA (poly lactic acid), and can be manufactured with a 3D printer. The container 210 is circular and can be manufactured in a size that can accommodate 200 ml to 1,000 ml of liquid collection medium.

The processor of the control panel 130 may control the drive motor 130 so that the collector 230 rotates at a predetermined rotation speed. For example, the processor may control the collector 230 to rotate at a predetermined rotational speed based on at least one of the humidity and temperature of the surrounding environment in which the chamber 110 is located. When the humidity of the surrounding environment is low, the collection medium evaporates quickly from the pillars 231 exposed to the outside of the collection medium in the collection medium 230, so it is necessary to rotate the collection medium 230 at a faster speed than when the humidity is high. There is. However, if the collector 230 rotates at too fast a rotation speed, the film of the collection medium formed on the pillar 231 is destroyed and the collection medium leaves the collector 230 and scatters. The maximum rotational speed of the collector 230 allowed may be predetermined in consideration of the physical characteristics of the collection medium.

Additionally, the processor of the control panel 130 controls the rotation direction of the collector 230 through control of the drive motor 130. For example, the processor may control the collector 230 to rotate clockwise for a predetermined time and then rotate counterclockwise for a predetermined time. The time for which the collector 230 rotates clockwise and the time for which it rotates counterclockwise may be the same or different.

As a further example, the liquid collection tank 200 may be configured to adjust the angle of the circular disk 233 with respect to the surface of the collection medium. If, due to the characteristics of the microorganisms, bacteria or viruses to be collected, direct collision with the surface of the collection medium has better collection efficiency, the tilt angle of the circular disk 233 is adjusted to be small, and due to the characteristics of the microorganisms, bacteria or viruses to be collected, If the collection efficiency is better when the collection medium collides with the pillar on which the film is formed, the collection efficiency can be improved according to the characteristics of each microorganism by adjusting the tilt angle of the circular disk 233 to be larger.

Figure 7 is a side view showing the schematic configuration of a hazardous substance collection device according to another embodiment of the present invention. The hazardous substance collection device 100' according to another embodiment of the present invention includes a chamber 110, a fan 120, a control panel 160, a drive motor 170, a motor stand 180, and a liquid collection tank ( 300). Since the chamber 110 and the fan 120 have the same configuration as the above-described embodiment, detailed descriptions are omitted. Like the control panel 140 described above, the control panel 160 may be mounted outside the chamber 110 or implemented in the form of a terminal, and may be electrically connected to the fan 120 and the drive motor 170 through a wired or wireless connection. It is possible to control the operation of each component by being connected to .

The drive motor 170 rotates the pinion gears 326 and 327 by connecting two motors 171 and 177 to the rotation shafts 321 and 325 of the corresponding two pinion gears 326 and 327, respectively. The drive motor 170 may receive a control signal from the control panel 160 and rotate the pinion gears 326 and 327 at a predetermined rotation speed and at predetermined cycles.

FIG. 8 is a perspective view showing the liquid collection tank 300 connected to the drive motor 170 in the hazardous substance collection device 100', and FIG. 9 is an exploded perspective view of the liquid collection tank 300. The liquid collection tank 300 is stored in the chamber 110, and the collection body 330 is configured to be able to move up and down in the container 310. The container 310 accommodates a liquid collection medium (for example, triple distilled water) for collecting hazardous substances, and has a sufficient height so that the collection body 330 can move up and down as necessary.

In order to move the collector 330 up and down, two rack gears 336 and 337 are provided on the rim of the circular disk 333 of the collector 330, and the rack gear has two corresponding pinion gears 326 and 327. ) is aligned with. As described above, the pinion gears 326 and 327 are rotated by the drive motor 170, so that the collector 330 can move linearly up and down.

A plurality of pillars 331 are provided on the upper surface of the disk of the collector 330, and the detailed configuration of the pillars 331 is the same as that of the pillar 231 of the collector 230 described above, so detailed description is omitted.

However, the shape of the collector 330 is not limited to a circular shape, and may be a square plate or polygonal plate shape instead of a circular disk. In this case, unlike the shape of the container 310 shown, the bottom surface 314 may be square or polygonal. In addition, unlike the embodiment of FIG. 1, the bottom surface 314 of the container body 312 of the liquid collection tank 310 is horizontal. Other than that, since it is similar to the container 210 described above, detailed description will be omitted.

The processor (not shown) of the control panel 160 is electrically connected to the drive motor 170 and can control the vertical movement of the collector 330. For example, when the collection device 100' is operated, the processor operates the drive motor 170 so that the collector 330 repeats the movement of rising and falling above the surface of the collection medium at a predetermined cycle (see arrow in FIG. 7). You can control it. The cycle of repeating the up-and-down motion of the collector 330, the time it is exposed outside the collection medium, and the time it is immersed in the collection medium may each be determined based on the characteristics of the microorganism, bacteria, or virus to be collected.

The drive motor 170 may be supported by the motor stand 180 and may be fixed within the chamber 110 through the motor stand 180.

As a further embodiment, the hazardous substance collection device according to the present invention may be configured so that the collection body can move both up and down and in rotation.

The average of the last three values was obtained. As a result, it was confirmed that the collection device (H-Guard) of the present invention had better collection performance in all sizes than the control bio-sampler (SKC).

Experimental Example 3: Dry film counting method (3M Petrifilm, Coliform Count Plates) - Bacteria detection

Figure 12 (a) shows the bacteria collection solution from the control bio-sampler (SKC) cultured on a dry film medium, and Figure 12 (b) shows the bacteria collection solution from the collection device (H-Guard) of the present invention being cultured on a dry film medium. This is the performance evaluation result obtained by culturing.
