ULTRAVIOLET STERILIZATION AND CLEANING DEVICE EQUIPPED WITH DETECTION AND DETERMINATION FUNCTION OF ULTRAVIOLET LIGHT/CRACKING, AND THE LIKE

摘要

PPROBLEM TO BE SOLVED: To provide an ultraviolet sterilization and cleaning device which, even when a plurality of water supply ports exist in a building, can clean/sterilize the whole of water from the plurality of the water supply ports in the building by installing only one device, and an ultraviolet sterilization and cleaning device which can produce water suitable for drinking immediately from raw water such as underground water, spring water, pond water, and river water at a site such as a construction site, a disaster recovery site, a battlefield, and a mountaineering path. PSOLUTION: The cleaning device has a foreign matter removal means for removing foreign matter contained in the raw water, a means removing chlorine, and the like, for adsorbing/removing chlorine or chlorine compounds contained in the raw water, an ultraviolet sterilization part for sterilizing the raw water by ultraviolet irradiation and decomposing a water cluster of the raw water into smaller clusters, and a means for detecting the illuminance of ultraviolet light irradiating in the ultraviolet sterilization part or a means for detecting a crack in an ultraviolet light emitting part or in its component such as a protecting tube.
