Estimating the term…
An ultraviolet irradiation device includes an inner cylinder forming a treatment flow path, an inflow portion allowing the object to flow into the treatment flow path, an outer cylinder accommodating the inner cylinder, a light emitting element irradiating the object passing through the treatment flow path with ultraviolet light, an O-ring dividing a space provided between an outer circumferential surface of the inner cylinder and an inner circumferential surface of the outer cylinder into a first chamber through which the object before ultraviolet irradiation passes and a third chamber through which the object after the ultraviolet irradiation passes, and a second chamber communicating with the first chamber through communication holes. The second chamber communicates with the treatment flow path through a plate.
An ultraviolet irradiation device, comprising:
An ultraviolet irradiation method configured to allow an object to flow from an inflow portion into a treatment flow path formed inside a cylindrical portion having one open end and extending in a longitudinal direction and irradiating the object passing through the treatment flow path with ultraviolet light, the method comprising:
