Title:
ULTRAVIOLET IRRADIATION DEVICE
Document Type and Number:
Japanese Patent JP2018149213
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ultraviolet irradiation device exhibiting high energy utilization efficiency, which is capable of effectively utilizing heat of an ultraviolet LED for sterilizing viruses and the like in fluids.SOLUTION: An ultraviolet irradiation device 1 includes: a fluid storage 2 formed in the middle of a flow passage 3; a first on-off valve 5 for opening and closing a fluid inlet port 4 of the fluid storage 2; a second on-off valve 7 for opening and closing a fluid discharge port 6 of the fluid storage 2; and an ultraviolet LED 17 which is disposed in a lower part at the center of the inside the fluid storage 2 for irradiating ultraviolet light toward an upper side of the fluid storage 2. The inner wall face of the fluid storage 2 is formed as an ultraviolet reflection face. Further, the ultraviolet LED 17 is designed to irradiate the ultraviolet light in a state where the first on-off valve 5 closes the fluid inlet port 4 and the second on-off valve 7 closes the fluid discharge port 6 to confine the fluid inside the fluid storage 2.SELECTED DRAWING: Figure 1
