Device for recycling and processing
of rubber-plastic waste

Recycling of used tires at the proposed installation is carried out by dry pyrolysis. The process takes place at a temperature of 500 degrees without access of air. The fuel used is not condensed gases. Waste car tires recycled as a whole, without pre-butchering. Tires are stacked in a working chamber of the reactor by singly.

After filling the working chambers, the temperature in the chamber rises to 500 degrees. When the temperature rises over 500 degrees, the water is injected into the chamber to stabilize the temperature. Turning into steam the water dilutes the products formed by the decomposition of rubber, and prevents the occurrence of secondary reactions with the formation of toxic substances. Furthermore, water vapor does not support combustion process and prevents the self-ignition of the received products. The process of decomposition of rubber is going on during an hour. Then, the water is injected into the working chamber to prevent the escape of pyrolysis gas in the environment and reducing the temperature to about 200 degrees. After that it is overlapped the valve on the outlet pipe of vaporous pyrolysis products. After the process of decomposition the cover of working chamber is opened and steel wires and solid wastes (coke) are pull out. The evaporated water is condensed and mixed with the received pyroliser. Hereinafter, this water helps to clean pyroliser from water-soluble salts, chlorides, ammonia , amines, oxygen- and sulfur-containing compounds , to produce high quality gasoline, diesel and oil fractions. Pallets are moved to places of accumulation of coke and wire for unloading. The received pyroliser is pumped into storage tanks for further treatment.

The finished product:

  • The oil fraction ( a mixture of hydrocarbons which is similar of its properties with fuel oil M 40 ) - 42 %.
  • Pyrolysis gas ( high-calorie fuel gas having a the heat of combustion of 32-38 MJ/m mainly consisting of hydrogen, methane , ethane , propane, butane , carbon oxides ) - 12 %.
  • Metal cord - 8%.
  • Coke (Technical coal and 85 % carbon black ) - 35 %.

Coke characteristics obtained on the plant:

  • Moisture - 13%
  • Ash - 13.2%
  • Sulfur content - 2.31 %
  • Volatile - 4%
  • Carbon on dry benzene state - 95.5 %
  • High heat of combustion - 34131 kJ / kg

Therefore, the solids of pyrolysis can be used as a good fuel.

The main parameters:

  • Productivity - 1 - 1.5 tons per day
  • The size of the installation of the dry pyrolysis - 2500 * 1100 * 600 mm
  • The necessary working area - 100 m2, of which 20 m2 under cover ( can be simple )
  • Power - 1 kW / h
  • Personnel - 2 people

Installation, commissioning, start-up of equipment is carried out by our specialists as soon as possible. This technology has a patent support.
