no. 1 Embodiment approach
[0016] refer to Figure 1A , Figure 1B The ultraviolet water treatment device 100 according to the first embodiment will be described. Figure 1A is a schematic cross-sectional view of the ultraviolet water treatment device 100, Figure 1B From Figure 1A Viewed in the direction of arrow A Figure 1A Diagram of the UV water treatment plant.
[0017] The ultraviolet water treatment device 100 includes an ultraviolet irradiation unit 110 , an inlet pipe 120 for water to be treated, and an outlet pipe 130 for water to be treated arranged coaxially with the inlet pipe 120 .
[0018] The ultraviolet irradiation unit 110 includes a cylindrical shield (cylinder) 111 that is open at both ends and has a constant inner diameter. The central axis of the cylinder 111 is perpendicular to a surface including one open end of the cylinder 111 and a surface including the other open end. On the peripheral wall of the cylinder 111, a first opening 1111 and a second opening 1112 are provided t...
no. 2 Embodiment approach
[0037] refer to Figure 3A , Figure 3B The ultraviolet water treatment device 200 related to the second embodiment will be described. Figure 3A is a schematic cross-sectional view of an ultraviolet water treatment device 200, Figure 3B From Figure 3A Viewed in the direction of arrow A Figure 3A Diagram of the UV water treatment plant. exist Figure 3A and Figure 3B in, for with Figure 1A and Figure 1B The same reference numerals are assigned to the same elements, and detailed description thereof will be omitted.
[0038] The ultraviolet water treatment device 200 is provided with a plurality of (in Figure 3A , Figure 3B In addition to two box-type ultraviolet irradiation subunits, it has the same Figure 1A and Figure 1B Same construction.
[0039] The first box-type ultraviolet irradiation subunit 210 constituting the ultraviolet irradiation unit includes a cover 211 in the shape of a hollow cuboid whose both ends are open. A first cover 212 and a secon...
no. 3 Embodiment approach
[0056] refer to Figure 4A and Figure 4B An ultraviolet water treatment device according to a third embodiment will be described. Figure 4A is a schematic cross-sectional view of the ultraviolet water treatment device 300, Figure 4B From Figure 4A Viewed in the direction of arrow A Figure 4A A diagram of the ultraviolet water treatment device 300. exist Figure 4A and Figure 4B in, for with Figure 1A and Figure 1B The same reference numerals are assigned to the same elements, and detailed description thereof will be omitted.
[0057] In the ultraviolet water treatment device 300 of this embodiment, the outer diameter of the cylindrical shield 111 is smaller than the inner diameters of the inlet pipe 120 and the outlet pipe 130 . The inlet pipe 120 and the outlet pipe 130 form a single pipe body. That is, in the ultraviolet water treatment device 300 , the cylindrical shield 111 having an outer diameter smaller than the inner diameter of the single pipe body is...
