Abstract

Przedmiotem zgłoszenia jest sposób termicznej redukcji tlenków żelaza z użyciem wodoru oraz urządzenie do tego procesu. Sposób wg wynalazku polega na tym, że termiczną redukcję tlenków żelaza przeprowadza się w dwóch wydzielonych technologicznie i szczelnie zamkniętych przestrzeniach, a mianowicie w zbiorniku (13) pieca kołpakowego (11) oraz w retorcie (7), która jest usytuowana w zbiorniku pieca kołpakowego (11), bezpośrednio na zbiorniku ciśnieniowym. Z kolei urządzenie wg wynalazku jest wyposażone: w piec kołpakowy (11) z trzonem podporowym (3) do osadzania kontenera (2) wsadu (1) w retorcie (7), natomiast poniżej trzonu (3), wewnątrz współosiowo usytuowanego cylindra termicznego (16), jest także współosiowo osadzony cylinder termiczny (17) z wewnętrzną nagrzewnicą wodoru (20) w obudowie nośnej (19), przy czym pomiędzy ściankami cylindrów termicznych (16) i (17) jest osadzony pierścieniowy wymiennik ciepła (18), a ponadto do nagrzewnicy wodoru (20), za pośrednictwem wymiennika (18), jest przyłączona linia doprowadzenia wodoru.The subject of the application is a method for thermal reduction of iron oxides using hydrogen and a device for this process. The method according to the invention consists in the thermal reduction of iron oxides being carried out in two technologically separated and tightly closed spaces, namely in the tank (13) of the cap furnace (11) and in the retort (7), which is located in the tank of the cap furnace ( 11), directly on the pressure tank. In turn, the device according to the invention is equipped with: a cap furnace (11) with a support shaft (3) for placing the container (2) and the charge (1) in the retort (7), below the shaft (3), inside the coaxially located thermal cylinder (16). ), there is also a thermal cylinder (17) with an internal hydrogen heater (20) mounted coaxially in the supporting housing (19), and an annular heat exchanger (18) is mounted between the walls of the thermal cylinders (16) and (17), and in addition to The hydrogen supply line is connected to the hydrogen heater (20) via the exchanger (18).
