Abstract

The invention provides a method and a system for cracking waste rubber. The waste rubber is sequentially sent to a low-temperature thermal cracking chamber, a high-temperature thermal cracking chamberand a microwave cracking chamber which respectively have an oxygen-free or oxygen-deficient environment, wherein thermal cracking of the waste rubber in the low-temperature thermal cracking chamber is carried out in a 200-400 DEG C environment, thermal cracking in the high-temperature thermal cracking chamber is carried out in a 500-800 DEG C environment, and microwave cracking in the microwave cracking chamber is carried out in a 500-800 DEG C environment; a cracking oil gas generated in the cracking process is continuously discharged from the low-temperature thermal cracking chamber, the high-temperature thermal cracking chamber and the microwave cracking chamber; and solids generated in the cracking process are recovered. The method and the system can effectively reduce the energy consumption in the cracking process and improve the cracking efficiency of the waste tire and the quality of cracked carbon black.

Description

technical field [0001] The invention relates to a waste rubber cracking method and system, in particular to a composite cracking method combining heat transfer cracking and microwave cracking, which can be used for cracking waste tires and the like, and belongs to the technical field of circular economy and energy saving and emission reduction. Background technique [0002] With the mass production of waste tires, the recycling and processing industry of waste tires has made great progress. my country produces nearly 400 million waste tires every year, and it is necessary to vigorously develop the recycling and processing industry of waste tires. At present, my country's waste tires are mainly used to produce reclaimed rubber and rubber powder. Reclaimed rubber production consumes a lot of energy and causes heavy pollution, and is gradually being eliminated worldwide. Rubber powder products have not yet been widely used in my country's market, and production capacity is limit...
