Description

1280897 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a method for recycling organic waste, and more particularly to a method for recovering recycled organic waste by using a catalyst reaction. [Prior Art] Due to the depletion of energy use and the implementation of the Kyoto Protocol of the United Nations Framework Convention on Climate Change (UNFCCC) in 2005, the development of renewable energy has become a top priority for all countries. The recycling of waste is not only an environmental issue, but its development goal is to treat waste as a “raw material” renewable resource and create economic benefits. For wastes widely used in wire and cable, ratio converters, and transformer insulators, including thermoplastic polyethylene (PE), thermosetting decane crosslinked polyethylene (Si-XLpE), and thermosetting epoxy resin ( EPOXY RESIN), etc., which are also commonly used to refill grease (the most common oil brain) as a waterproof and moisture resistant functional requirement. These industrial municipal wastes need to be recycled and reused. This recycling process not only requires environmentally friendly responsibilities, but also produces high-quality renewable metals, clean metals that are not damaged by mechanical and electrical properties. However, today's general thermosetting polyethylene, resin transformers, transformers, wire and cable, and many composite materials are based on landfill burial and incineration. These phenomena originate from the traditional mechanical treatment method, which separates the metal and the body into a processing spindle in a destructive manner. Some of the plastics with high plasticity and easy moldability (polyethylene, polyethylene) are recycled and reused; others have been contaminated (such as paint and grease...) (four), can not be re-polluted _, J^ Cover recycling and recycling will eventually lose physical properties and need to be eliminated; the metal part is also contaminated with insulation, which will cause secondary pollution during recycling. In addition, thermosetting cross-linked polyethylene and thermal epoxy resin are difficult to recycle due to low fluidity and poor moldability, and ultimately they are incinerated or buried, which is not only easy to cause pollution, but also violates the sustainability of UNFCCC. The common goal of development. 〆 Most of the current commercialization of resource-resourced solid organic waste is “thermal cracking technology. This type of technology converts solid organic waste into high-weight, light-weight fuel, LPG. And renewable resources such as coke. In addition to the waste of 1280897, _ will add waste _ ^ grease because the organic waste has very low thermal conductivity, heating up: cracking is completed, relatively uneconomical; _ at ^ w It is not easy to expand 're-treatment can meet the safety of the =; _ column of oil' must pass through the vine, the use of _=: production = ^ ^ solution = solution processing is often because of gas, solid blockage caused by fire, explosion; broken, The solved mantle is fully produced and recorded, which is also the problem of the prior art. The main purpose of the present invention is to provide a catalyst 庶 庶 = recycled organic waste The treatment method, the two-stage cracking reaction, in addition to the ability to handle wastes containing thermosetting plastics and paints and greases, can greatly improve the utilization rate of equipment and the yield of regenerated oil and the quality of organic waste. Cracked The completeness of the coke produced by the solution is extremely robust, and can be processed in the following way. The processing of the rubber waste is..., the processing is made into slave smoke or active, and the coke processed by plastic waste can be processed. Made of hollow monuments or aggregates, such as direct burial and no pollution to the environment. The whole process is environmental, safety and economic benefits. Therefore, in order to achieve the above objectives, the use of catalyst reaction to recover recycled organic The waste treatment method comprises the following steps: First, the organic waste and the catalyst are placed in a vertical cracking furnace to be the first stage cracking gas and the solid product, and basically, the reaction temperature is higher than 220~230. The cracking reaction can be produced at °C. The optimum treatment temperature is 350~380 °C, and the reaction pressure is micro-positive pressure. Then, the first-stage cracking gas will be sent to the top of the vertical cracking furnace, and the solid product is generated by gravity. Remaining in the bottom of the vertical cracking furnace, and discharging the solid product into the rotary secondary cracking furnace to continue the reaction, the reaction temperature is about 365 ° C ~ 390 ° C, can produce the second stage of cracking gas and The oil is degreased, and the residue left by it includes coke, metal, etc. The first stage cracking gas, the second stage cracking gas and the cracking oil can be naturally treated by various separation steps such as filtration, condensation, distillation, etc. The oil is collected and collected. 6 1280897, this issue, is divided into two stages of the cracking reaction of organic waste. In the first stage, the solution is to use the vertical cracking furnace to generate the first stage cracking gas and solids. The object can be directly separated, and the problem of blockage is generated. Then, through the rotary cracking furnace, the solidification product can be used to improve the cracking efficiency, and the mica or the fossil can be used together.
