Title:
APPARATUS AND METHOD FOR PREVENTING TOXIC MATERIAL DISPERSION BY MEANS OF VORTEX AIR CURTAIN
Document Type and Number:
WIPO Patent Application WO/2017/183763
Kind Code:
A1
Abstract:
The present invention relates to an apparatus and method for preventing toxic material dispersion by means of a vortex air curtain, and more specifically, to: an apparatus for preventing toxic material dispersion by being installed near a facility, such as a containment building of a nuclear power plant, where the danger exists of a toxic material leak in case of an accident, and by forming an air curtain by means of an artificial air flow rotating around the surroundings of the facility; and a method therefor. According to the present invention, in a toxic material leak situation, such as a radiation leak in a containment building of a nuclear power plant, an air curtain is formed by means of an artificial air flow rotating around the surroundings of the facility where the leak has occurred, and thus the toxic material is captured by such vortex air flow, and by means of the curtain effect of the vortex air flow, the facilitation of the dispersion of such toxic material by means of an external flow, such as the influence of a surrounding wind, is prevented, and at the same time, the toxic material is collected and removed, and thus the surrounding areas are not impacted despite the leak accident.
