Recently, the first micro waste negative pressure pyrolysis technology production line for smart waste tires jointly developed by Shandong Chengyuan Environmental Protection Group Co., Ltd. and Korea Dongcheng Group is about to be put into production, which will enable waste tires to generate 35% of industrial carbon black and 40% of fuel oil. , 15% of steel wire and 10% of gas combustible gas, to achieve recycling of used tires 100% environmentally sound recycling. China is the country with the largest volume of used tires. There are about 260 million annual and nearly 9.5 million tons of tires. If these waste tires are improperly recycled, they will become “black garbage†and cause serious environmental pollution. The process flow of the production line is to send the tire scraps to the feeding port through a forklift, pass the belt conveyor and the bucket elevator into the thermal decomposition system and decompose at a high temperature of 600°C. The carbon black and steel wire pass through the carbon black processing area. First, the steel wire is separated and sent to the steel wire storage area. The carbon black is processed into about 350 mesh, and then sent to the carbon black storage area after carbon black packaging; the fuel oil passes through the oil and gas separation device. After collection, it is sent to the oil tank area; gas gas is sent to the hot gas generator for combustion and energy self-sufficiency is achieved. "Micro-negative pressure pyrolysis technology is the world's most advanced technology for disposing of used tires. No waste water, waste gas and waste residue are produced in the entire production process, achieving safety, environmental protection and energy conservation." Sun Qingli, chairman of Shandong Chengkou Mining Group, said that the single production line The company disposes of 68 tons of waste tires and handles 20,000 tons a year. After all five production lines are put into production, they will be capable of handling 100,000 tons of used tires annually. Zhu Jun, president of the China Tire Renovation and Recycling Association, said that the increasing use of used tires and scrap tires has become a global issue. He said: "The tires refurbished 2-3 times, or after a certain number of regeneration can not be refurbished or recycled it, micro vacuum pyrolysis technology is the most effective way of waste rubber eat dry pressing the net, the last of a process means."
