The main actions and operating principles of the apparatus for removing pollutants in the air according to an embodiment of the present invention configured as described above are as follows.

First, air is sucked into the device by the suction force generated by the operation of the air pump 20, is filtered first by the intake filter 10, and then passes through the suction hose 31 to the lower liquid phase of the impinger 30. As it is injected into the area, it creates a vortex.

At this time, secondary filtering collects and separates various contaminants such as nucleic acids such as RNA and DNA or mycoplasma present in the air through precipitation, dissolution, or reaction while the air in the impinger 30 and the collection liquid are mixed. processing takes place

In this process, the air in the impinger 30 is uniformly distributed and distributed while passing through the first distributing plate 71, and the moisture in the gas passing through the first distributing plate 71 is absorbed into the first porous body. Since it is absorbed by (81), the gas can be discharged in a non-differentiated and stable state due to the uniform distribution of gas and rapid flow in the first place.

In addition, the first heater 91 can heat and remove moisture in the first porous body 81 by opening and closing a switch that automatically operates when a condition range such as a predetermined time or temperature is reached.

Thereafter, the air filtered in the impinger 30 rises in the form of bubbles and gathers in the upper gas phase area of the impinger 30, and passes through the discharge hose 32 by the air pressure difference and the blowing pressure of the exhaust fan 50. It moves to the damper 40.

That is, the liquid in the gas discharged from the impinger 30 is filtered by the damper 40 and moved to the exhaust filter 60 through the discharge hose 41 by the forced ventilation action of the exhaust fan 50 in a dried state In the exhaust filter 60, non-particulate matter in the gas is tertiarily filtered and discharged out of the device.

In this process, the air in the damper 40 is uniformly distributed and distributed while passing through the second distributing plate 72, and the moisture in the gas passing through the second distributing plate 72 is absorbed into the second porous body ( 82), it can be discharged in a non-differentiated and stable state due to the secondarily uniform distribution of gas and rapid flow.

In addition, the second heater 92 can heat and remove moisture in the second porous body 82 by opening and closing a switch that automatically operates when a condition range such as a predetermined time or temperature is reached.

Meanwhile, the control unit 23 determines whether the amount of air sucked in by the air pump 20 and the amount of air discharged by the exhaust fan 50 are the same or the amount of air exhausted to the outside by the exhaust fan 50 determines the amount of air pump 30. By controlling the amount of air sucked in by the fan to be greater than the amount of air sucked in, the air can move smoothly.

<Test example>

In order to confirm the pollutant removal effect of the airborne contaminant removal device according to an embodiment of the present invention, a real-time genetic analysis test was performed using a universal real-time PCR equipment (BioRad, CFX96) and human GAPDH.

In the case of Example 1, the first distributing plate 71 and the first porous body 81 shown in FIG. 3 were maintained, sterilized distilled water was passed through as a collecting liquid, and air passed through the exhaust filter 60 was released into the air. It was connected to the intake filter of the contaminant removal device and collected again by the impinger 30. In the case of Example 2, the apparatus was configured in the same manner as in Example 1 except that 0.1N hydrochloric acid was used as the collecting liquid.

For DNA extraction, DNA was isolated using Qiagen's DNdeasy Blood & Tissue Kits, and the real-time PCR reaction composition solution obtained by mixing 10 μl of 2x master mix and 5 μl of Primer/probe mix with 5 μl of isolated DNA is shown in the table below. Reacted under the same conditions as in 1. The results are shown in Figures 5 to 7.

temperature hour number of cycles 95℃ 10 mim 1 time 95℃ 10sec 40 times 60℃ 30sec 40 times
