Description
A. Process
principle
Full continuous atmospheric
pressure waste tyre pyrolysis equipment adopted automatic
feeding,automatic deslagging,the materials in the reactor,screw
driving from the low temperature area to high temperature area and
pyrolysis,high automatic,big capacity,high safety.Sloved many
shortcoming of the fixed bed type and othe types pyrolysis
equipments,quantity production,low capacity,long cycle,big
consumption,heavy physical labour,bad working environment.In the
meanwhile,solved the rotary kiln’s problem,many sealed
point,potential safety and air pollution because of it is easy
leakage of oil-oulet and hole of material discharging. Full
automatic atmospheric pressure waste tyre pyrolysis equipment
adopted original inner screw propeller,not only ensure the
materials heating uniformly,pyrolysis fully,but also ensure the
pyrolysis gas and carbon black powder separated fully,incomparable
advantage with the rotary kiln pyrolysis machine which the
pyrolysis gas mixed with carbon and no separated space,easy to
bring vast carbon black powder and block the tubes,equipment and
pollute the quality of oil.
B.Process
flow
1. The cut waste tyre pieces are fed into feeding machine and
preheated then transported into the reactor. Materials are driven
forward in the reactor and pyrolyzed. The gas passes through the
evaporation pipe on top of the reactor and enters the gas liquid
separator. The broken down carbon black and steel wires are
discharged by the auto discharging machine into the carbon black
conveyor, and the steel wires are seperated from the carbon black
with the magnetic selector. The carbon black will be given to the
carbon black processing machine.
2．The condensed fuel oil comes into relay tank.When oil
level of relay tank upto the fixed height,then use pump into the
storage tank.
3. The waste gas was discharged from the top of relay tank
into waste gas buffer tank, inhaled by the vacuum pump into air
liquid seperator, where the waste gas is seperated from liquid and
goes into water sealed tank. From the water sealed tank, waste gas
enters the hot air furnace for burning.
4．Cooling water is sucked by the pump from water recycling
pool and sent to the condenser tubes. Water travels in the tube
from bottom to top and returns to recycling water pool.
5．Steam is generated by the boiler and is passed to the
pyrolysis kettle feeding steam inlet, discharging steam inlet and
kettle internal inlet, being over heatedby the kettle and finally
enter the kettle.
6．Fuel oil is dehydrated in the storage tank, sucked by the
pump, passing the filter and goes into the fuel oil tank. The oil
is supplied to the steam boiler and hot air furnace.
