waste rubber pyrolysis equipment Operating procedures
Since the 1970s, some industrialized countries have begun to study the use of waste tires. For example, Japan and the United States use scrap rubber tires as fuel for power generation or manufacturing of cement. However, since the 1990s, Britain, the United States and many other countries have interest in the cracking of waste rubber tires, these countries are using about 1000 high-temperature cracking, the drawback is the high energy consumption, poor quality of cracked carbon black, low yield.
I crack the equipment manufactured by the company has solved these problems, is the current international and domestic more advanced disposal of waste tires of the common equipment, the use of the principle of dry distillation, the use of a scientific closed production process, you can maximize waste , And does not produce secondary pollution. After the waste into the cracking furnace, close the feed gate (according to the equipment production capacity charge), in accordance with the operating procedures for operation, you can safely and smoothly get oil. Through the entire production process, the resulting waste gas after purification treatment sent to the furnace combustion, this can not be at room temperature can not be condensed gas can not be discharged into the atmosphere, while the furnace combustion of dust will be more advanced dust removal device Disposed of. The device has excellent configuration, greater use of energy, with less combustion value to achieve greater thermal efficiency. ◆ China is the world's largest rubber consumer, its consumption accounted for nearly one-third of the world's total rubber consumption, while the world's largest rubber importer, more than 75% of natural rubber and more than 40% Synthetic rubber is dependent on imports, of which natural rubber import dependence (75%) has been higher than oil (60%), iron ore and grain, the first column. Rubber has become an important strategic resource for the development of China's national economy.
China's natural rubber annual output of about 800,000 tons, the future growth of production is also very limited, resulting in China's rubber resources are very scarce countries, the contradiction between supply and demand is very prominent, the shortage of rubber resources on the impact of national economic development has become increasingly prominent.
◆ tire consumption of rubber accounted for about 70% of the total consumption of rubber. Data show that China's waste tires in 2013 for more than 300 million, weighing 15 million tons, equivalent to natural rubber resources of about 5.3 million tons, if all the recycling, the equivalent of China's 6.5 years of natural rubber production.
◆ China's annual production of waste tires is expected to increase by 5% per year, the amount of waste tires in 2020 is expected to exceed 20 million tons. Production of 1 ton of low-end tires need 3-4 tons of oil, the production of 1 ton of high-end tires about 8 tons of oil. According to the average 1 ton tire needs 6 tons of oil, the production of 20 million tons of tires need 120 million tons of oil, which is equivalent to Daqing Oilfield 3 years, Shengli Oilfield 4 years of exploitation. Which for our country such a nearly 60% of the oil and more than 75% of natural rubber, nearly 50% of the synthetic rubber need to import the country, its strategic significance is unusual.
◆ tire products in the ratio of synthetic rubber and natural rubber 6: 4, rubber and industrial carbon black ratio of 2: 1. Production of 1 ton of synthetic rubber needs 3 tons of oil, the production of 1 ton of industrial carbon black needs 2.17 tons of fuel oil, 3.5 tons of oil.
◆ tires in the industrial carbon black about 30%, now 15 million tons of waste tires, the need for 4.5 million tons of industrial carbon black, equivalent to 15.75 million tons of oil, equivalent to Liaohe Oilfield 1.5 years of mining. Waste tires after pyrolysis of carbon black due to ash, the proportion of up to 35%, the effective development of recycling to achieve significant significance.
