A plastic pyrolytic conversion vessel comprises a conveying mechanism for moving a liquid, or a semi-molten, or a molten waste material, or a solid inert residue, or any combination thereof through the vessel. During pyrolyzation of the waste material, the same is heated and vaporized and undergoes in situ chemical reactions comprising cracking, recombination, reforming, recracking, and the like, and is subsequently removed from the vessel. A plurality of scraper blades serve to mix the liquid, or the semi-molten, or the molten waste material, or a solid inert residue, or any combination thereof and convey the waste material forward toward a vessel egress. In another embodiment, one or more sweeping devices serve to move forward the waste material that is located between adjacent rotating conveyor devices.

Helical stirring system for a plastic conversion vessel

A plastic conversion feeding system serves to transport a feedstock through different processing units or stations to a vessel wherein chemical and/or physical reactions occur to produce suitable, useful end products. Various processing units include a homogenizer for breaking up said feedstock, a size reduction device for reducing the feedstock to particles and densifying the same, a heating and/or blending device for heating said feedstock, and a feed conduit connecting said heating and blending device to said vessel. The feedstock conversion unit vessel through various cracking, reforming, condensation, recombination, and recracking operations, produces a mixture of useful gases and condensable gases.

Plastic conversion feed system

The support mechanisms of the present invention comprise a vessel supported by suspension cables suspended from trollies that can move along the length (longitudinal) of a framework. The support system is such that waste material, even upon heating, cooling, etc., can constantly and smoothly move through the entire system, with the vessel generally being in a natural, balanced orientation.

Vessel support system

Plastic conversion vessels such as pyrolytic reactors convert plastic waste materials such as polymers, or hydrocarboneous material, or both, via in situ chemical reactions comprising cracking, recombination, reforming, recracking, and the like, to usable chemical compounds such as naphtha, diesel fuel, heavy oil, wax, and the like. Inherent within the polymers and/or carbonaceous material are generally solid, inert residues such as various fillers, pigments, flame retardants, silica, aluminum, talc, glass, clay, and so forth. Such solid inert residues (SIR) must be treated to remove residual volatile organic material therefrom in order to meet acceptable environmental standards and/or limits. A heated dryer for treating the SIR comprises heating units to remove excessive volatile organic material therefrom as when moved along a conveyor that transfers said material to a collection area. The collection area comprises one or more pistons that are capable of compacting and discharging said SIR material. Another collection area embodiment comprises a plurality of plungers that transfer the SIR material from said collection area to a plunger collection area, and subsequently to a collection container.
