Non-biodegradable waste pyrolysis system with selective residence-time reactor by recycle of self-sustaining heat-conservation medium

A self-sustaining waste breakdown system having:

• a preprocessing assembly which includes a grinder to grind the waste, a conveyer to convey the ground waste, a collector for receiving the ground waste and a heater to melt the ground waste;
• a heating assembly for providing heat to the heater to melt the ground waste and which has a heat exchanger, a burner and a furnace;
• a filtering assembly which has a medium filtering-adjusting mechanism provided between the furnace and the burner to recycle the medium, wherein the filtering-adjusting mechanism includes a transmission pump, a high speed centrifugal filter, a pressure gauge, a safety relief valve, a flow meter, an inlet, a level sensor, a thermometer and a viscosity sensor;
• a reaction assembly which has a reaction chamber connected respectively with a second worm of the preprocessing assembly and a high temperature pump, the gas tank, a condenser connected to the reaction chamber, the fuel tank and the gas tank, wherein the improvements comprise:
• the reaction chamber has a filtering layer to retain long chain molecules of the melted waste for continuous breakdown so as to change the long chain molecules into short chain molecules;
• and
• the filtering-adjusting mechanism is provided to recycle the medium with a special concentration, viscosity and heat resistance in the reaction chamber.
