Title (EN) ULTRAVIOLET IRRADIATION DEVICE FOR WATER TREATMENT AND WATER TREATMENT METHOD USING ULTRAVIOLET IRRADIATION
(FR) DISPOSITIF DE RAYONNEMENT ULTRAVIOLET POUR LE TRAITEMENT DE L'EAU ET PROCÉDÉ DE TRAITEMENT DE L'EAU UTILISANT UN RAYONNEMENT ULTRAVIOLET
(JA) 水処理用の紫外線照射装置、及び紫外線照射を利用した水処理方法
Abstract:
(EN) An ultraviolet irradiation device is provided with: a flow path structure (6) inside which flow paths (5) linking an inlet (1) and an outlet (2) are formed; a flow limiting unit (30A) disposed within the flow paths (5); ultraviolet light emitting diodes (25) for emitting ultraviolet rays toward the flow paths (5); and at least one collimating optical system (27) for forming the ultraviolet rays sent out by the ultraviolet light emitting diodes (25) into a beam of collimated light. The flow limiting unit (30A) has a first opening (31) and a second opening (32) for allowing raw water to pass through. The first opening (31) is positioned closer to the ultraviolet light emitting diodes (25) than the second opening (32). The surface area of the second opening (32) is greater than the surface area of the first opening (31).
(FR) Un dispositif de rayonnement ultraviolet comprend : une structure de passage (6) à l'intérieur de laquelle des circuits de flux (5) reliant une entrée (1) et une sortie (2) sont formés; une unité de limitation de débit (30A) disposée à l'intérieur des circuits de flux (5); des diodes électroluminescentes ultraviolettes (25) qui émettent des rayons ultraviolets vers les circuits de flux (5); et au moins un système optique de collimation (27) qui forme les rayons ultraviolets émis par les diodes électroluminescentes (25) ultraviolettes dans un faisceau de lumière collimatée. L'unité de limitation de débit (30A) possède une première ouverture (31) et une seconde ouverture (32) pour permettre à l'eau brute de passer. La première ouverture (31) est positionnée plus près des diodes électroluminescentes (25) ultraviolettes que la seconde ouverture (32). La surface de la deuxième ouverture (32) est supérieure à la surface de la première ouverture (31).
(JA) 紫外線照射装置は、流入口(1)及び流出口(2)に連通する流路(5)が内部に形成された流路構造体(6)と、流路(5)内に配置された流れ制限部(30A)と、流路(5)に向かって紫外線を発する紫外線発光ダイオード(25)と、紫外線発光ダイオード(25)から発せられた紫外線を平行光線にする少なくとも1つのコリメート光学システム(27)を備える。流れ制限部(30A)は、原水の通過を許容する第1開口部(31)および第2開口部(32)を有し、第1開口部(31)は第2開口部(32)よりも紫外線発光ダイオード(25)に近い位置にあり、第2開口部(32)の面積は第1開口部(31)の面積よりも大きい。
