Please refer to FIG. 1 and FIG. 2 at the same time, which is a schematic diagram of the structure and configuration of the organic polymer waste recycling system of the present invention. Here, the dotted line in FIG. 1 indicates the gas flow direction, and the solid line indicates the Solid or liquid orientation. The present invention discloses an organic polymer mixture treatment device and an organic polymer waste recovery and treatment system; it is explained herein that the organic polymer mixture treatment device according to the present invention is a part of the organic polymer waste recovery and treatment system, mainly the entire The front-end processing part of the architecture of the waste recovery and treatment system, and the entire waste recovery and treatment system will be described in detail below. The system mainly includes a flue gas circulation unit 10, a granulation integrated dechaining unit 20, an oil and gas separation unit 30, and a Waste material recovery unit 40.

The organic polymer waste recycling and processing system described in the present invention mainly considers the establishment of a fast, safe and energy-saving combustion mechanism, and the establishment of a waste material and waste recycling mechanism, which are described in the following points:

A. Environmental control of positive pressure oxygen barrier: The combustion reaction needs to block the intrusion of oxygen-containing air to form a stable thermal cracking environment to prevent organic matter from burning: for example: fire and gas explosion, a large amount of gas will be formed during thermal cracking. When positive pressure is generated and the pressure drops when there is no thermal cracking, the front and rear channels of the thermal cracking furnace can be closed to prevent the introduction of air, and the introduction of water and gas is used to provide the necessary positive pressure system during operation to establish a true positive pressure operating environment.

B. Introduce the water-gas pressure-stabilized reaction mechanism: use water to form water vapor to generate expansion thrust, which can force the organic gas in the thermal cracking furnace out of the thermal cracking furnace, and can use water gas to generate thrust. Airflow exclusion may introduce oxygen-containing air, which has the effect of rejecting first oxygen, and can use water vapor to reduce the reactants to prevent the reaction from being too intense (because there will be a lot of exothermic phenomenon when the reaction temperature is too high, there will be operational risks) to ensure safe operation and increase In addition to the stability of the reaction, in addition to atomized water vapor, water droplets can also be replaced by water vapor or inert gas.

C. Vertical feeding mode: The main consideration is the hot gas rising principle to prevent thermal convection when reactants are fed into the thermal cracking furnace. When moving from directly above, the thermal gas rising of the thermal cracking furnace will not cause convection. It can also be introduced with water gas. A large amount of water vapor is generated, and a strong thrust is provided to move the reactants into the thermal cracking furnace that may be entrained with air, which makes the operating system safer, and there is no chimney effect to introduce air from below.

D. Establish a safe exhaust mechanism: a large amount of gas will be generated during the thermal cracking reaction, and it is necessary to let the gas quickly exit the thermal cracking furnace. In order to prevent the pressure from rising, the exhaust channel must be opened. Stop, in order to prevent the backward gas from flowing back, the exhaust mechanism must be opened and closed, and a water seal is formed through the rise of the water level to obtain the purpose of stable control.

E. Organic gas condensation and compression recovery mechanism: After the organic gas produced by the thermal cracking process is condensed and compressed, it can form condensed oily organic matter (macromolecules), and the material with high ignition point will form tar with carbon ash, but cannot condense organic gas. The gaseous combustible gas (small molecules) has a low ignition point. Separate recovery can improve recovery and reuse, improve recovery efficiency, and have more energy saving and carbon reduction effects. In addition to reusing fuel oil such as tar and organic gas for fuel reuse , Can also be processed into industrial chemicals.

F. Granulation treatment and recovery mechanism of combustion product carbon slag: powdery carbon ash of different sizes generated in the thermal cracking process can be granulated and dried to form carbon black of uniform size and low water content and recover it. Utilization can be used as the purpose of the supply of raw waste in related industries to increase the value of commercialization.
