Abstract

Strumień powietrza atmosferycznego (10) miesza się ze strumieniem odparowanego gazu kriogenicznego (12), zaś przepływ powietrza atmosferycznego (10) i przepływ odparowanego gazu kriogenicznego (12) reguluje się w zależności od żądanej temperatury strumienia roboczego na wyjściu końcówki roboczej (15). Ciekły gaz kriogeniczny (1) odparowuje się w wymienniku ciepła (13) za pomocą strumienia powietrza atmosferycznego (10), po czym strumień schłodzonego powietrza atmosferycznego (11), który w wymienniku ciepła (13) oddał swoje ciepło na odparowanie ciekłego gazu kriogenicznego (1), miesza się ze strumieniem odparowanego gazu kriogenicznego (12) i kieruje do końcówki roboczej (15). Urządzenie do otrzymywania strumienia zimnych gazów, posiadające izolowany termicznie zbiornik (2) z ciekłym gazem kriogenicznym (1) doprowadzanym przez zawór (4a) do wymiennika ciepła (13) oraz rury zasilające (7), zawory (4b, 4c) i kanał dolotowy (27) powietrza atmosferycznego z pierwszą komorą mieszania (16) połączoną z końcówką roboczą (15) poprzez rurowy przewód kriogeniczny (14). Zgodnie z wynalazkiem, wewnątrz kanału dolotowego (27) powietrza atmosferycznego (10) jest umieszczona wężownica (8) z króćcem wylotowym (19) odparowanego gazu kriogenicznego (12) znajdującym się w komorze mieszania (16), zaś króciec wylotowy (26) pierwszej komory mieszania (16) połączony jest z końcówką roboczą (15) poprzez rurowy przewód kriogeniczny (14).The stream of atmospheric air (10) is mixed with the stream of vaporized cryogenic gas (12), and the flow of atmospheric air (10) and the flow of vaporized cryogenic gas (12) are regulated depending on the desired temperature of the working stream at the outlet of the working end (15). The liquid cryogenic gas (1) is vaporized in the heat exchanger (13) by means of the stream of atmospheric air (10), and then the stream of cooled atmospheric air (11), which has given up its heat in the heat exchanger (13) to vaporize the liquid cryogenic gas (1), is mixed with the stream of vaporized cryogenic gas (12) and directed to the working end (15). A device for obtaining a stream of cold gases, comprising a thermally insulated tank (2) with a liquid cryogenic gas (1) supplied through a valve (4a) to a heat exchanger (13) and supply pipes (7), valves (4b, 4c) and an atmospheric air inlet channel (27) with a first mixing chamber (16) connected to the working end (15) via a cryogenic tubing (14). According to the invention, a coil (8) is placed inside the atmospheric air inlet channel (27) (10) with an outlet connector (19) of vaporized cryogenic gas (12) located in the mixing chamber (16), while the outlet connector (26) of the first mixing chamber (16) is connected to the working end (15) via a cryogenic tubing (14).
