Title (EN) FILTER FOR COLLECTING CHLORINATED ORGANIC COMPOUND
(FR) FILTRE POUR LA COLLECTE DE COMPOSE ORGANIQUE CHLORE
(JA) 塩素化有機化合物の採取用フイルター
Abstract: front page image
(EN)A collection filter with which various chlorinated organic compounds contained in either a particulate or gaseous state in a fluid are simultaneously collected and the chlorinated organic compounds collected can be easily extracted. The collection filter (7) comprises: a fluid-permeable molding comprising a fibrous material and an inorganic binder for binding the fibers to one another; and held in the molding a hydrophobic material having higher hydrophobicity than the fibrous material and inorganic binder. The collection filter (7) is disposed in a holder (6) having a discharge passage (12a). When a sample gas containing various chlorinated organic compounds is introduced from a flue (25) into the holder (6) via a collection pipe (2) and an introduction pipe (8), then the various chlorinated organic compounds, including dioxins, contained in either a particulate or gaseous state in the sample gas are collected with the collection filter (7) when the gas passes therethrough. The compounds collected are discharged outward from the discharge passage (12a).
(FR)L'invention concerne un filtre pour la collecte de composé organique chloré, permettant de recueillir simultanément divers composés de ce type (particules ou gaz) dans un fluide, et de les extraire aisément. Le filtre (7) comprend: un moulage perméable aux fluides en matériau fibreux et un liant inorganique pour les fibres de ce matériau; dans le moulage, un matériau hydrophobe à hydrophobicité supérieure à celle du matériau fibreux et du liant. Le filtre (7) est placé dans un étui (6) à passage d'évacuation (12a). Lorsqu'un gaz échantillon à plusieurs composés de ce type est introduit depuis un conduit d'évacuation (25) dans l'étui (6), via un canal de collecte (2) et un canal d'introduction (8), ces composés (particules ou gaz), y compris les dioxines, sont recueillis dans le filtre (7) au moment du passage du gaz, puis évacués par le passage d'évacuation (12a).
(JA)流体中に含まれる粒子状態およびガス状態の両方の形態の各種の塩素化有機化合物を同時に捕捉して採取し、しかも採取した塩素化有機化合物を容易に抽出することができる採取用フイルターである。この採取用フィルター7は、繊維材料と、当該繊維材料同士を結合するための無機系結合材とを含む流体通過性の成形体と、当該成形体に保持された、繊維材料および無機系結合材よりも疎水性の高い疎水性材料とを備えている。排出路12aを有するホルダー6内に採取用フイルター7を配置し、煙道25から採取管2および導入管8を経由してホルダー6内に各種の塩素化有機化合物を含む試料ガスを流入させると、当該試料ガス中に含まれる粒子状態およびガス状態の両方の形態のダイオキシン類等の各種の塩素化有機化合物は、採取用フイルター7を通過する際に捕捉されて採取され、排出路12aから外部に排出される。
