The invention belongs to the technical field of resource utilization of waste tires, and relates to a rapid pyrolysis device and method for whole waste tires. The waste tires are symmetrically opened on the sidewall, and the waste tires after opening are sent to the folding feeding device, and then sent to the middle and lower part of the whole tire type fast pyrolysis device after passing through the water seal section to isolate the air, and come from the molten salt heating reflux device The high-temperature molten salt provides energy for the catalytic rapid pyrolysis of waste tires. During the pyrolysis process, pyrolysis volatile products and carbon black are produced. The volatile product is collected by the recovery device. At the same time, the steel wire precipitated during the pyrolysis process is pulled out of the whole tire type rapid pyrolysis device by the wire drawing device. Heat storage is carried out, and the molten salt with good heat storage returns to the whole tire type fast pyrolysis device again.
Description
Technical field[0001]The present invention belongs to the technical field of waste tire resource utilization, and in particular, there is a rapid pyrolysis device and method for waste tires.Background technique[0002]With the continuous improvement of technology and the continuous improvement of people's living standards, the automobile has gradually been widely used. At present, the amount of waste wheel produced annually has exceeded 15 million tons, but its recycling rate is less than 35%, so the resource treatment of waste tires It has become an urgent problem to be solved. The main treatment method of the waste tire has a renovation, rubber powder, regeneration rubber, incineration and pyrolysis. At present, internationally recognized thermal solution oil is the most potential to process the waste tire resource. However, for a long time, my country's waste tire pyrolysis technology is still generally in basic research and experimental stages.Inventive content[0003]In order to ov...
