Virus removal device

A virus removal device having a function to remove a virus from a gas, comprising:

• a cylindrical treatment room configured to introduce a gas and remove a virus from the gas;
• a catcher formed of a rotary brush, which is installed in the treatment room and configured to collect the virus contained in the gas;
• a liquid spraying mechanism installed in the treatment room;
• a rotary driving mechanism configured to rotate the catcher;
• a gas introducing portion configured to introduce the gas to the treatment room;
• a gas discharging portion configured to discharge the gas from which the virus has been removed from the treatment room;
• and
• a liquid discharging portion configured to discharge a liquid containing the virus that has been removed from the gas,
• wherein the gas is introduced from the gas introducing portion to the treatment room and the gas is discharged from the treatment room through the gas discharging portion by an action of only an airflow generated by rotation of the catcher formed of the rotary brush,
• wherein the gas introducing portion includes a first aperture formed on a first side of the treatment room, the first aperture being arranged so as to face away from the airflow such that the airflow flows along side the first aperture, and
• wherein the gas discharging portion includes a second aperture formed on a second side of the treatment room, the second aperture being arranged to face the airflow in an oncoming direction of the airflow such that the airflow is discharged through the second aperture of the gas discharging portion.
