Device for conducting continuous process of thermo-catalytic depolymerization of waste olefine plastics and method of conducting continuous process of thermo-catalytic depolymerization of waste olefine plastics

摘要

The object of the invention is a device which is a reactor (1) for the continuous operation of the process of thermo-catalytic depolymerisation of waste polyolefins of cylinder-shaped plastic as a two-dimensional structure consisting of a reactor dome (2) and a reactor (1) combined with a core (3) reactorTorah (1). The reactor core (3) has circular grooves (6) with rectangular cross-section and perpendicularly positioned circular grooves (7) with rectangular cross-section. The circular ditches (6) with a rectangular section have holes at the bottom (8) with diameter "?" less than the width of the ditch (6)Whereas heating units (9) with reciprocal heating are located in the grooves (7). In circular grooves (6) of rectangular cross-section, two-dimensional mixing blades (13) attached to the mixing arm work (12),which in turn are attached to the axis of the mixture (11). The holes (8) at the bottom of the ditches (6) are part of the exhaust pipes (14),through which the coke gravitationally falls to the burner (15),from which it is transported outside the device. Heating units (9) with double heating heat directly heat the vertical walls of the brake (7)and, indirectly, plastics dipped in ditches (6) through a mixture (13). Of abalone (15),by means of a system (16) to remove the coke from the device. The way in which the process of thermo-catalytic depolymerisation of polyolefins waste is carried out continuously is by introducing into the reactor (1) fragmented polyolefins waste,which are stretched into the circular shafts (6) of the reactor core (3) through the shoulder (12) of the mixing axis mixture (11). The waste introduced into the crankcase (6) downstream of the reactor (3) is mixed by two-dimensional mixing blades (13). The two-part blades of the mixture (13) through the hole in the reactor bed (8) the coke is extracted through the exhaust pipes (14) and the burner (15) outside the reactor (1). Cleaning of the reactor core (3) from the coke oven is done at a hot temperature, without interruption of the reactor operation (1),by sprinkling the reactor core (3) with gravel, which washes from the plaster and coke walls of the circular shafts (6) and the circular walls of the grooves (7) and which is then removed with impurities from the reactor (1).
