Abstract
Sposób ciągłego, termicznego rozkładu odpadowych poliolefin w temperaturze 380 - 450°C, wykorzystuje reaktor poziomy (3), zaopatrzony w obrotowy walec (6) z przymocowanymi, wyprofilowanymi łopatami (7), a jako surowiec stosuje się gorący roztwór zawierający roztworzone odpadowe poliolefiny poprzez ich traktowanie ciężką frakcją olejową, odebraną w sposób frakcjonowany w wyniku schłodzenia produktów termicznego rozkładu, bądź olejem z innych źródeł zewnętrznych. Możliwy jest też bezpośredni wtrysk w temperaturze poniżej temperatury wrzenia oleju, lub/i termicznie uplastyczniony przez obróbkę mechaniczną wsad polimerowy. Po ustaleniu ilości powstałego koksiku poreakcyjnego na poziomie 5%, zaprzestaje się podawania wsadu i po wydzieleniu produktów lotnych zmienia się kierunek obrotów walca reaktora (6) w celu usunięcia produktu stałego z reaktora w kierunku odbioru produktu bez konieczności wychładzania reaktora (3).The method of continuous thermal decomposition of waste polyolefins at a temperature of 380 - 450 ° C, uses a horizontal reactor (3), equipped with a rotary roller (6) with attached, profiled blades (7), and a hot solution containing dissolved polyolefin waste is used as the raw material their treatment with a heavy oil fraction, received in a fractionated manner as a result of cooling thermal decomposition products, or with oil from other external sources. Direct injection at a temperature below the boiling point of the oil is also possible, and / or a thermally plasticized polymer charge is machined. After setting the amount of post-reaction coke breeze at 5%, the feed is discontinued and after the separation of volatile products, the direction of rotation of the reactor cylinder (6) is changed in order to remove the solid product from the reactor in the direction of product collection without having to cool the reactor (3).
