The process of catalyzing tires by scrap tire shredder

The waste tire shredder machine is an important way to reduce air pollution and waste utilization. From the 1970s to the present, some countries with more developed industrial production have begun scientific research to use waste tires in daily life. For example, Japan and the United Kingdom use waste rubber tires as raw materials for power generation or concrete production. However, since the 1990s, many countries such as the United Kingdom, the United States, and other countries have become interested in the cracking technology of waste rubber tires. This type of country uses high-temperature cracking at around 1,000. The disadvantages are high energy consumption, poor quality of cracked carbon black, and production Low volume. In this article, the waste tires are crushed, and then under the effect of the metal catalyst, they only need to be heated to about 400 to make them cracked into cracked gas, cracked distillate oil and converted into carbon black. The cracked distillate oil can be fractionated to obtain gasoline, diesel engine, and fuel oil for automobiles. After scientific research and exploration of the processing technology plan and actual operation standards, it has succeeded in maintaining modernization and has achieved obvious economic benefits in 2 years of operation. The processing technology has the advantages of low energy consumption, good product quality, zero-polluting sewage discharge standards, simple and clear processing technology, and easy manipulation in actual operation. It is the world's best technology for solving waste rubber tires at this stage.

The standard for catalytic cracking of waste tires in the whole process of waste tire c rusher processing technology

Firstly, the rigid ring of the waste tire is separated and then sliced, first coarsely crushed, then crushed, and then sent to the reactor with the metal catalyst A-quantitative analysis via a continuous vibrating feeder, under certain temperature and working pressure Carry out the catalytic cracking reaction. According to the reactor, the raw material will wait for about 10 minutes in the reactor. Then it reflects that the material is sent to the gas-solid separation equipment for separation. The solid material is sent to the grinding stage by the continuous feeder, and the winnowing machine becomes Carbon black finished products. The personal gas obtained by the gas-solid separation equipment enters the cooler and the fractionation tower to separate out cracked gas, automotive gasoline fractions, diesel engine fractions, and high-quality fractions. After flue gas desulfurization and de-drying of automotive gasoline fractions and diesel engine fractions, the process standards, and reflection results, catalytic cracking reflection is the key factor in the entire process. The reactor is the key machinery and equipment in it, and the material of the reactor is specified to have relatively high corrosion resistance and heat resistance. The small-scale test equipment uses the volumetric gas-solid separation equipment, because the gas and carbon black have a large difference in the severity, and the two phases can be separated very easily. In order to reduce the composition of solid particles carried in the cyclone, the volume of machinery and equipment is sufficient to reduce the gas velocity. The fuel gas is sent to the cooler and enters the oil-gas separator tank to obtain cracked gas and distillate oil.

Analysis results of cracked gas composition radon gas methane gas hexane butadiene propane gas pe isobutane n-butane volume percentage/% component volume percentage/% 1 butene 2-butene 2-butene isoamyl Alkyl n-pentane, total pentane, hydrogen chloride, carbon dioxide, carbon monoxide, a small amount of water is brought into it during steam distillation, so the design of the processing technology is the whole process of drying, and the organic chemical sulfur and inorganic substances are removed by flue gas desulfurization. Sulfur is absorbed by the resin together to the required specification.
