Each year Americans discard about 240 million tyres, about one per person, most of which end up in landfills. In the meantime, 1.3 million gallons of used oil are disposed of, about 5 gallons per person, with 30 percent being dumped into landfills or down sewers. Besides harming our environment, this indicates a tremendous waste of resources. However, with the rapid development of science and technology, peolple try to use these re-sources, scrap tires and used oil are being converted to energy sources through tyre pyrolysis plant.
In Doing's tire pyrolysis process, firstly, make reactor rotate clockwise 0.4r/min, put the raw material into the reactor, close feeding door. Secondly, burned the fuel material (coal, or wood, or natural gas, oil) in the furnace. Reactor will be slowly heated, when the temperature reaches around 180℃, oil gas will come out, then go to the cooling system and liquid to oil. Some incondensable gas which can''''t cool down will be lead to the furnace through a gas pipe. It will be used to heat the reactor. This can save your energy. Only the first 2 hours use energy for heating. After the initial 2 hours mainly utilize gas, little energy is ok. After pyrolysis, all the oil gas come out from a reactor. The temperature will fall down. Then make it rotate anticlockwise. Carbon black discharging begins. Lastly, when the temperature deduces 50℃, worker can open the door of the reactor to take steel wire without. Thenceforward the next batch can be started .
For the market, the oil extracted from waste tires can be used for several products in different industry. It can be distilled to produce a marine or heating fuel and base lube oil stocks the same way that waste oils are now being recycled. The other components can be used for asphalt or if other options are not economical, the bulk of the tire oil can be turned directly into asphalt. Tire oil can also be refined like crude oil.
