Description

Thermal decomposition reactor for rubber scrap and rubber flack
It is a product that can recover energy sources due to lack of energy sources. It thermally decomposes polymer composite wastes such as organic compounds, waste rubber, waste plastics, and waste vinyl, such as carbon and hydrogen, and uses gas produced in this process. In the process of actively developing a process for using as a direct energy source such as driving the present invention, the present invention has an object to provide an efficient reactor for thermally decomposing the polymer composite waste.
As the shortage of energy sources has intensified, efforts have been made to recover energy sources from used products. The most representative energy source recoverable products are organic compound mixtures such as carbon or hydrogen, waste rubbers and waste plastics, and waste products. Polymer composite waste such as vinyl, waste wood, biomass, coal, emulsion, tar and the like. Polymer wastes of such raw materials or recyclable high calorific value components have high utility value when extracting value-added components that can be decomposed and recycled at high temperatures, and used as renewable resources or as new clean energy sources.
In general, energy recovery using waste technology includes dry burning, pyrolysis, and direct combustion. Recycling methods include mechanical grinding and micronization, and a method of converting and recovering a new product by cracking the bonds of molecules by applying heat at a high temperature.
By the way, the dry distillation incineration method described above has a problem that the secondary pollutants are generated by incineration along with the burden of initial facility costs due to the difficulty of mass processing. In recent years, household wastes are treated by pyrolysis gasification, but this may be appropriate in case of high throughput such as high initial investment cost and social investment such as accompanying facilities. Recycling and recycling relatively low value-added wastes is valuable in terms of protecting the environment and recovering recycled resources.
In addition, the method of decomposing the polymer composite wastes such as waste rubber under high temperature in the absence of oxygen is ideal in the reaction temperature range of 400 ~ 500 ℃ to decompose inside the reactor, these are put at room temperature It takes a long time to reach the optimum reaction temperature. In particular, since the uniform and effective reactor temperature is not maintained, the quality of the condensed oil recovered from the cracked evaporation gas extracted from the reactor is degraded, and the residues generated during the cracking process are unreacted or adhered to the inner wall of the reactor or the transfer device. As this is formed, there is a problem of lowering the heat transfer rate that the heating medium transfers into the reactor and sequentially causing decomposition performance of raw materials introduced into the reactor and normal operation of the transfer apparatus or fatal defects of the inner wall of the reactor.
In conclusion, the reactor that maintains the optimum reaction temperature uniformly in the reactor and minimizes scale formation of residues is a key device for recovering high value-added resources from decomposition of polymer composite waste. There is no continuous multi-stage cracking reactor that completely and safely overcomes.
The present invention has been made to solve the above problems, and relates to a reactor for thermally decomposing rubber scrap and rubber flakes, and more particularly, the inner tube of the reaction tube for thermally decomposing rubber scrap and rubber flakes; In the space between the exterior, the heat pipes, which are the moving passages of the heating medium, constitute the same interval around the inner tube, and are introduced from the condenser in a transfer line that sends the decomposition steam generated during the thermal decomposition of the heating medium to a condenser, which is a subsequent process.
