Abstract

Przedmiotem wynalazku jest przyrząd do rozpoznania skażeń, przeznaczony do wykrywania i identyfikacji skażeń toksycznych, umożliwiający identyfikację substancji gazowych w szerokim zakresie wilgotności. Przyrząd charakteryzuje się tym, że ma dwie komory DMS (3, 6), pomiędzy którymi znajduje się wymiennik (4) z półprzepuszczalną membraną (5). Pomiędzy wymiennikiem (4) i drugą komorą DMS (6) usytuowana jest zwężka (10). Wylot z komory drugiej (6) jest połączony poprzez pompę (12) i filtr (13) z sitami molekularnymi z wlotem komory drugiej (6) oraz równolegle, poprzez pompę (14) i filtr węglowy (15), z wylotem wymiennika (4). Wlot wymiennika (4) jest połączony z czerpnią powietrza (1), którego wylot jest połączony z wlotem komory pierwszej (3).The subject of the invention is a contamination recognition device, intended for detecting and identifying toxic contamination, enabling the identification of gaseous substances in a wide range of humidity. The device is characterized by two DMS chambers (3, 6), between which there is an exchanger (4) with a semi-permeable membrane (5). A restrictor (10) is located between the exchanger (4) and the second DMS chamber (6). The outlet from the second chamber (6) is connected through a pump (12) and a filter (13) with molecular sieves to the inlet of the second chamber (6) and in parallel, through a pump (14) and a carbon filter (15), with the exchanger outlet (4). . The inlet of the exchanger (4) is connected to the air intake (1), the outlet of which is connected to the inlet of the first chamber (3).
