Waste Pyrolysis Plant

Pyrolysis is when the polymer structure is converted to the lower substructure under hypoxic conditions. It could decompose hazardous substances and reduce environmental pollution. So pyrolysis technology is used to treat solid waste, it not only maximizes energy recovery but also be treated harmlessly.

The advantage of pyrolysis

Pyrolysis could significantly reduce the production of harmful substances. Compared with incineration, pyrolysis generated gas of dioxin is lower, and does not generate dust.

Pyrolysis could convert solid waste into gas and biochar. The gas could used for heating and generating electricity, realizing energy recycling. Biochar can be used as a soil amendment or as a raw material for activated carbon. The treated solid waste slag could turn into a harmless stable substance.

The pyrolysis adapts a continuous method to improve the efficiency of treatment. At the same time, because the pyrolysis reaction is carried out under high-temperature conditions, it reduces the processing cycle.

Materials of waste pyrolysis

Municipal sludge: sewage treatment plant sludge, pipe network sludge, river sludge
Industrial sludge: chemical sludge, dyeing sludge, electroplating sludge, paper mill sludge
Petrochemical industry: oil mud, oil sands, waste tires, waste plastics, waste oil, waste catalysts, oil-containing filter media
Hazardous waste: waste medical supplies, expired drugs, drug extract residue, pesticide residue, waste aluminum plastic, coal tar,

The pyrolysis process

STEP1:Preparation: Preparation includes sorting, crushing, compression, etc. It is to improve the efficiency of pyrolysis. The prepared material rubbish enters the incinerator through a feed system.
STEP2: Feedstock: The rubbish is burned in an incinerator. The generated heat causes the material in the waste to undergo a pyrolysis reaction. The temperature inside the incinerator should controlled at 800℃ to ensure pyrolysis.
STEP3: Pyrolysis: The rubbish of the organic material undergoes thermal cracking under high temperatures. And then generate combustible gas, tar, coke, and other substances. In the pyrolysis process, the harmful substances in the waste are decomposed and the pollution to the environment is reduced.
STEP4: Cooling: The high temperature of gas and carbon black is cooling in the furnace. The cooling system mainly includes a cooler cooling fan and so on. The cooled material can be further processed.
STEP5: Collection and utilization of combustible gase: Pyrolysis generates a sea of tail gas to meet environmental requirements. Waste water treatment mainly includes precipitation, filtration, disinfection, and other operations to reduce pollution to the water environment.

The pyrolysis equipment

Feeder

It is used for material that is transported from the outside to the pyrolysis furnace and feed and heat in the feed process to a molten state before entering the reactor. This design helps obstruct the internal space of the feed module preventing outside air from entering the reactor.

Pyrolysis system

The pyrolysis furnace is one of the common solid waste pyrolysis equipment. Solid waste is heated and decomposed by an external heat source. It is mainly classified into two types: Vertical and horizontal. It has the advantage of being simple and easy to operate, and exhaust gas treatment is convenient. The furnace is suitable for small-scale rubbish.

Cooler

It is designed to convert solid waste into reusable resources through pyrolysis. Air cooling takes advantage of air generated by the blower to cool.

The gas treatment

The high temperature of the gas is cooled and dedusted through the flue condenser and spray tower. Finally the tail gas is discharged from the chimney.
