Rotary Pyrolysis Kiln

The rotary pyrolysis kiln system comprises a cylinder with a heating chamber on the outside, an inlet at the front part of the cylinder, an outlet at the rear end and a pyrolysis gas outlet. A flue gas outlet is provided above the heating chamber. The inlet port is connected to a feeding system and the outlet port is connected to a solid slag cooling system. The pyrolysis gas outlet is connected to a pyrolysis condensation system. The heat source combustion chamber and burner are connected to the flue gas inlet. The flue gas outlet is connected to a waste heat recovery system. The waste heat recovery system is connected to the burner inlet. The pyrolysis gas condensation system is connected to the end of the gas purification and collection device and recycling device. The recycling exercise is connected to the hot air furnace. The recycling system includes a water sealing device, a natural gas fan, a gas water sealing device at the end of the pyrolysis gas condensation system, and a combustion fan into the burner. The feed system includes a silo, and a feed screw reamer. The silo is connected to the feed screw reamer via a feed airlock box. The tail end of the feed screw reamer is connected to the feed opening of the rotary kiln. The front end of the burner is provided with a fuel inlet, a combustion air as soon as possible and a pyrolysis gas inlet. The waste heat recovery system includes a waste heat recovery device, which has two inlets: one is connected to the combustion fan, and the other is connected to the flue gas. Waste heat recovery device has two outlets, one outlet for the combustion air inlet of the combustion chamber is connected, the other outlet is linked to the induced draft fan, gas purification and treatment devices and chimneys and so on.


The discharge cooling system includes a discharge cooler, provided with a discharge airlock, and the discharge airlock is connected to the discharge cooler.
The pyrolysis gas condensation system includes: a gas and solid separator, a spray tower, and a condenser. The gas and solid separator is connected to the pyrolysis gas outlet. There is a circulating water pump inside the spray tower, and the spray tower and condenser bottom army yo connect to the liquid collection system.

 

The rotary kiln has high thermal efficiency, large processing capacity, tight sealing, uniform heating, easy to control the temperature, pyrolysis time and so on. Relatively more environmentally friendly and efficient than solid waste incineration. Applicable to: waste plastics, electronic waste, biomass, waste rubber, waste lithium batteries and other industry sectors. The whole set of production line adopts advanced technology, environmental protection and high efficiency, with high economic benefits and social value. Equipped with waste heat recovery system, the flue gas after heat exchange through the pyrolysis rotary kiln passes through the pyrolysis rotary kiln. The flue gas enters the waste heat recycler. The heat exchange can be used to preheat the combustion air. After the waste heat recovery, the flue gas passes through the induced draft fan into the flue gas purification and treatment device. The flue gas is discharged after it has been treated to the required standard. The heat can be reused from the points, and the pyrolysis efficiency is high. It can realise the gradual use of energy and energy saving and emission reduction. In addition, pyrolysis gas condensation system recycling system. Pyrolysis gas passes through the spray tower for rapid cooling. Condensable substances are condensed in the intercooler. The condensable substances are in liquid state. A portion of the non-condensable gas passes through a fan for incineration in a hot air furnace. Thus the recovery of non-condensable gases is realised.
