Description
Przedmiotem wynalazku jest urzadzenie do zamrazania — szybkiego chlodzenia produktów reakcji plazmochemicznych zwlaszcza tlenków azotu.Dotychczas mieszaniny produktów reakcji prowadzonych w stanie plazmy w temperaturze okolo 8000° K byly schladzane w dyszach Lavala lub w urzadzeniach pierscieniowych z promieniowo wykonanymi otworami przez, które do strumienia plazmy doprowadzano wode jako medium chlodzace.Niedogodnoscia tych urzadzen byly male predkosci schladzania strumienia plazmy co powodowalo znaczny rozklad produktu reakcji.Celem wynalazku jest usuniecie powyzszych niedogodnosci przez konstrukcje urzadzenia, którego istota polega na tym, ze sklada sie z dyszy Lavala posiadajacej 0,5 mm szczeline prostopadla do osi dyszy, wykonana w najwezszym miejscu dyszy, najkorzystniej w odleglosci okolo jednej czwartej dlugosci dyszy od wlotu dyszy, przez która doprowadza sie wode do strumienia plazmy.Korzystnym skutkiem wynalazku jest mozliwosc regulacji ilosci wody doprowadzanej do strumienia plazmy w szerokim zakresie.Urzadzenie do zamrazania produktów reakcji pracuje zwykle w ukladzie: katoda —dysza —anoda — urzadzenie do zamrazania produktów reakcji i jest przedstawione na rysunku w przekroju wzdluznym.Urzadzenie sklada sie z korpusu górnego 1, korpusu dolnego 2, dyszy 3 przedzielonej 0,5 mm szczelina 4 prostopadla do osi usytuowana w najwezszym miejscu dyszy w odlegloscijednej czwartej dlugosci dyszy od wlotu dyszy. Woda chlodzaca produkty reakcji jest doprowadzana do szczeliny 4 przewodem 5. a woda chlodzaca urzadzenie do korpusu 2 przewodem 6. Przy pracy reaktora i urzadzenia ilosc doprowadzanej do strumienia plazmy wody reguluje sie zaworem na przewodzie 5.Zastrzezenia patentowe 1. Urzadzenie do zamrazania produktów reakcji plazmochemicznych skladajace sie z dyszy Lavala, wodnej instalacji chlodzacej, znamienne tym, ze dysza posiada w najwezszym miejscu prostopadla do osi dyszy szczeline o przeswicie 0,5 mm, która doprowadza sie wode do strumienia plazmy. 2. Urzadzenie wedlug zastrz. 1, znamienne tym, ze szczelina umiejscowiona jest w odleglosci okolojednej czwartej dlugosci dyszy od wlotu dyszy.119 221 Pracownia Poligraficzna UP PRL. Naklad 120 egz.Cena 100 zl PLThe subject of the invention is a device for freezing - rapid cooling of the products of plasmochemical reactions, especially nitrogen oxides. Until now, mixtures of reaction products carried out in the plasma state at a temperature of about 8000 ° K were cooled in Laval nozzles or in ring devices with radial holes through which the plasma stream was fed water as a cooling medium. The inconvenience of these devices was the low cooling speed of the plasma stream, which resulted in a significant decomposition of the reaction product. to the axis of the nozzle, at the highest point of the nozzle, most preferably at a distance of about a quarter of the length of the nozzle from the mouth of the nozzle through which water is fed to the plasma stream. The advantage of the invention is that it is possible to regulate the amount of water supplied to the streams and plasmas in a wide range. The device for freezing the reaction products usually works in the following system: cathode-nozzle-anode - device for freezing the reaction products and is shown in the longitudinal section of the figure. The device consists of the upper body 1, lower body 2, nozzle 3 slot 4 separated by 0.5 mm perpendicular to the axis located at the narrowest point of the nozzle at a distance of one fourth of the nozzle length from the nozzle inlet. The water cooling the reaction products is supplied to the slot 4 through the line 5. and the water cooling the device to the body 2 through the line 6. During the operation of the reactor and the device, the amount of water supplied to the plasma stream is regulated by the valve on the line 5. Patent claims 1. Device for freezing the products of plasma chemical reactions consisting of a Laval nozzle, a water cooling system, characterized in that the nozzle has a slot at its narrowest point perpendicular to the nozzle axis with a clearance of 0.5 mm, which leads the water to the plasma stream. 2. Device according to claim 1, characterized in that the slot is located approximately one-fourth of the nozzle length from the nozzle inlet. 119 221 Pracownia Poligraficzna UP PRL.
