Claims

[Scope of Claim for Utility Model Registration] A cylindrical box with both ends closed, an elliptical cylindrical reflector with a mirror surface formed inside and gaps at both ends in the front and back directions, and irradiates ultraviolet rays. It comprises a discharge tube, a hollow tube made of a material that transmits ultraviolet rays, a pair of curved partition plates, a pair of air flow distribution plates having elongated holes, and a ventilation device having a damper and an induced draft fan, The box body has an air intake port and an air outlet port on both sides and the center of the front surface thereof, respectively, and the reflecting mirror is arranged so that the long axis direction of the ellipse substantially coincides with the front and back direction of the box body. The discharge tube and the hollow tube are placed inside the body, and the discharge tube and the hollow tube are placed at positions substantially coinciding with two focal axes of the ellipse, and the partition plate surrounds the outside of the reflecting mirror. The outer wall of the partition plate and the inner wall of the box body form a cooling space passage communicating with the air intake port, and the inner wall of the partition plate and the outer wall of the reflecting mirror a cooling air bypass passage communicating with the air outlet, and the air flow distribution plate is removably disposed on the outlet side of the cooling air bypass passage, and is close to the discharge tube of the reflector. The gap on the side communicates with the inlet side of the cooling air bypass passage, and the gap on the side closer to the hollow tube communicates with the air outlet, and the opening area and opening of the hole in the air flow distribution plate An ultraviolet irradiation device characterized in that its position is selected to match a required air flow distribution.
