Description

Dry Photocatalyst Air Shower Sterilization Booth

The present invention relates to a booth through which a visitor of a specific place passes. In particular, in order to prevent infection of others due to contamination by foreign substances in a specific place by the visitor or infection by an infectious disease, foreign substances are removed from the visitor and sterilizing pathogens to prevent infection configured to do so.

A booth is installed at the entrance to control who enters a specific place.

These booths are mainly used for the purpose of detecting metals, for disinfection of vehicles entering livestock, etc., for purifying booths that spray air to remove foreign substances attached to the body or clothes to prevent internal contamination of semiconductors or pharmaceutical manufacturing rooms. There are commercialized booths for quarantine purposes.

In addition, in order to remove foreign substances and sterilize pathogens, wet prevention is sometimes performed by spraying a disinfectant in the form of a mist with a sprayer or the like. When performing wet disinfection using disinfectant, it must be carried out on objects or livestock in a well-ventilated space. The reason is that when a mist-type disinfectant enters a person's lungs through the respiratory tract, it can cause lung disease.

In recent years, with the development of transportation means, the number of people moving between countries is increasing, so there is a problem in that pathogens generated in one country are easily and quickly transmitted to the world.

In order to prevent such a problem, it is required to install rapid disinfection equipment, etc. that can prevent and purify all entrants in a specific place, for example, at the immigration checkpoint of an airport, to protect the citizens.

However, as the purification booth described above only performs the function of removing foreign substances with strong wind, it is difficult to remove pathogens on clothes, body, and daily necessities with strong wind. In this case, there is a disadvantage in that there is a risk of respiratory diseases of those who are subject to disinfection and those who perform disinfection.
