Abstract
Proces pirolizy prowadzi się w reaktorze i co najmniej jednym przegrzewaczu połączonych w pętlę. Do reaktora dozuje się odpady tworzyw, które kontaktuje się z ogrzaną masą z przegrzewacza, a następnie z reaktora transportuje się masę do przegrzewacza, po czym w przegrzewaczu podgrzewa się ją do temperatury wyższej niż temperatura depolimeryzacji tworzyw. Prędkość przepływu masy z reaktora do przegrzewacza dobiera się w zależności od pojemności przegrzewacza tak, aby przegrzewacz był zawsze napełniony a ogrzana w nim przeponowo masa przelewała się na jego końcu przeciwległym do miejsca podawania surowca do reaktora. W przegrzewaczu zachodzi przegrzewanie stopionych tworzyw, inicjacja depolimeryzacji oraz depolimeryzacja części surowca. Reaktor może być ogrzewany gazami spalinowymi, elektrycznie lub w dowolny inny sposób. Wymuszony zostaje stały ruch surowca. Ze względu na wypełnienie przegrzewacza surowcem ewentualnie powstające lotne produkty depolimeryzacji są zawieszone w fazie ciekłej. Lotne produkty depolimeryzacji powstałe w przegrzewaczu są uwalniane i odbierane na górze reaktora razem z lotnymi produktami depolimeryzacji zainicjowanej w przegrzewaczu a powstałymi w reaktorze i wszystkie powstałe lotne produkty następnie poddawane są dalszej obróbce w znany sposób.The pyrolysis process is carried out in a reactor and at least one superheater connected in a loop. Waste plastics are dosed into the reactor, which are contacted with the heated mass from the superheater, and then the mass is transported from the reactor to the superheater, after which it is heated in the superheater to a temperature higher than the depolymerization temperature of the plastics. The mass flow rate from the reactor to the superheater is selected depending on the capacity of the superheater so that the superheater is always filled and the membrane heated mass overflows at its end opposite the feed site to the reactor. The superheater overheats molten materials, initiates depolymerization and depolymerisation of some of the raw material. The reactor can be heated with flue gas, electrically or in any other way. Constant movement of raw material is forced. Due to the superheater being filled with the raw material, any volatile depolymerization products that are formed are suspended in the liquid phase. The volatile depolymerization products formed in the superheater are released and collected at the top of the reactor together with the volatile depolymerization products initiated in the superheater and formed in the reactor and all resulting volatile products are then further processed in a known manner.
