Dust collection hood

Abstract

This item is a dust collection hood for a laser decontamination system that performs surface decontamination of an object by irradiating its surface with a laser. It is designed to collect substances and dust that are detached from the object by laser irradiation and remain inside the hood. To efficiently collect substances and dust that remain inside the hood, a suction hose is connected to the lower end of the hood, and a slit for taking in outside air is formed at the upper end of the hood. As shown in each figure, the width of the slit narrows downwards from the outside air intake side in the upper half, while the slit width remains constant in the lower half that connects to it. As shown in perspective view 1, one opening surface with a slit formed at the upper end is in close contact with the object so as to cover the area of ​​the object that will be laser-irradiated. A laser irradiation device is connected to the other opening.
