Semi-continuous tyre pyrolysis plant for sale
Continuous Pyrolysis Plant / Date:07-15-2023
Semi-continuous tyre pyrolysis plant for sale is a kind of waste to energy plant developed and newly launched by Henan Doing Company. It adopts green processing technology, which offers innovative waste tyre recycling solution and can bring great economical and environmental benefits.
Process flow of semi-continuous tyre pyrolysis plant
1. Sealed feeding
Feed the rubber powder into pyrolysis reactor through the sealing sealed screw conveyor, which can complete the feeding operation of the reactor without opening the furnace door.
Noted: Batch type pyrolysis plant uses manual or hydraulic feeder to feed the whole tyres; while the semi-continuous type tyre pyrolysis plant requires to pretreate waste tyres into 16-18mm rubber powder.
2. Preheat the reactor
After the feeding is completed, turn on the burner to gradually heat the pyrolysis reactor, and at the same time rotate the pyrolysis reactor to ensure uniform and rapid heating. It usually takes about 2-3 hours for preheating reactor.
3. Pyrolysis
Under the condition of high temperature, the rubber powder undergoes pyrolysis and gasification reaction in the reactor. When the temperature reaches 280-320°C, a large amount of oil gas will be precipitated, and the oil gas will enter the condensation system for cooling into fuel oil.

4. High temperature slag discharge
After the oil gas are fully pyrolyzed, the carbon black in the reactor is discharged into the small pyrolysis reactor for cooling and discharging; then we can start the next pyrolysis process.
The semi-continuous tyre pyrolysis plant can realize high-temperature slag discharge, which can improve production efficiency while saving energy and reducing consumption.

5. Condensation into oil
Oil gas come out from the gas outlet of the semi-continuous pyrolysis plant reactor and first pass through the buffer tank, the mud blocking tank, and then the water tank condenser/tube condenser to cool into oil and store in the oil tank.
6. Exhausted gas and flue gas purification
The remaining non-condensable combustible gas contains harmful gases such as hydrogen sulfide. After being purified by the desulfurization and deodorization system, it can be recycled and used to heat the reactor to save its own fuel. The flue gas generated in the pyrolysis plant reactor heating process can be directly discharged after the desulfurization and denitrification treatment.

Applications of the final product of semi-continuous tyre pyrolysis plant
1. Pyrolysis oil
It can directly replace fuel oil for industrial or boiler heating, such as cement plants, steel plants, glass plants, brick plants, heavy oil generators, HFO(heavy fuel oil) power plant, etc.;
It can be refined into diesel by waste oil distillation plant and used as light fuel for diesel generators, combustion engines, heavy machinery and agricultural machinery, such as tractors and ships.
2. Carbon black
It can be used for industrial heating by briquette combustion, and its combustion calorific value is equivalent to that of coal, which can directly replace coal;
It can be finely milled to make semi-reinforcing carbon blacks such as N550, N660, and N774, which can be used as additives for pigments and rubber products.

3. Steel wire
Sell it directly to the steel factory for smelting or waste recycling. The semi-continuous tyre pyrolysis plant draws out the steel wire in advance before pyrolysis, what is produced is a shiny and thin steel wire. Therefore, its appearance and quality are very good, and the market price is also high.
4. Combustible gas
After the combustible gas passes through the exhaust gas purification system, it can return to the reactor as fuel for heating and recycling.
