Abstract

The invention relates to a reactor for gasifying and/or purifying, in particular depolymerizing, plastic material (12), comprising a reactor vessel (14) for holding the plastic material (12) and a heater (18) for heating the plastic material (12) in the reactor vessel (14), the reactor vessel being at least partially filled with a metal bath (26). According to the invention, a deceleration device (24, 32) is provided in an interior (22) of the reactor vessel (14) to decelerate a flow of liquefied plastic material (12) in the reactor vessel (14), said deceleration device (24, 32) having a plurality of elements (25) that are movably arranged in the interior (22).

Claims

1. A reactor for gasifying and/or cleaning, in particular for depolymerizing, plastic material with

(a) a reactor vessel for holding the plastic material, and

(b) a heater for heating the plastic material in the reactor vessel,

(c) the reactor vessel being at least partially filled with a metal bath,

characterized by

(d) a deceleration device arranged in an interior of the reactor vessel to decelerate a flow of liquefied plastic material in the reactor vessel,

(e) said deceleration device having a plurality of elements that are movably arranged in the interior.

2. The reactor according to claim 1, wherein the elements are made from ferromagnetic material.

3. The reactor according to claim 1, wherein the deceleration device is designed in such a way that it forces the liquefied plastic material onto a meandering path.

4. The reactor according to claim 1, wherein the heater is an inductive heater.

5. The reactor according to claim 1, characterized by at least one restraint device for the prevention of the flotation of the elements, in particular the balls.

6. The reactor according to claim 1, wherein at least one restraint device is connected to at least one movement device for moving the restraint device up and down.

7. The reactor claim 1, wherein the restraint device is connected to a motor, so that the restraint device can be moved in an oscillating movement, in particular along a longitudinal axis (L) of the reactor vessel.

8. The reactor according to claim 1, characterized by a plurality of restraint devices which can be automatically moved independently from each other in an oscillating movement, in particular along a longitudinal axis (L) of the reactor vessel.

9. A process for at least partially decomposing, in particular depolymerizing, and/or purifying plastic material characterized by the steps:

(a) introduction of the plastic material into a reactor vessel that is at least partially filled with a metal bath,

(b) heating of the plastic material by means of a heater, and

(c) deceleration of a flow of liquefied plastic material in the reactor vessel by means of a deceleration device arranged in an interior of the reactor vessel, which comprises a plurality of movable arranged elements.

10. The process according to claim 9, wherein the reactor is being operated in such a way that a ratio of the volume taken in by the elements and a reactor vessel volume of the reactor vessel has a value of at least 15% up to the filling level of the metal bath.
