DOING latest design batch type waste tyre/plastic pyrolysis production line 3D video
2022-01-18 / VideoThis 3D video shows the working process of the latest design batch type pyrolysis pyrolysis plants, which include six waste tire/plastic to fuel oil production lines. A complete batch pyrolysis production line including waste tire feeders, pyrolysis reactor, cooling system, oil tank and exhuast gas cleaning system.
As the video displays, batch pyrolysis plant is a closed pyrolysis reactor where each batch cycle involves separate stages: feeding, pyrolysis reaction, cooling and product collection, slag discharge, and flue gas treatment. Each stage requires a certain amount of time; operators can only begin the next batch after the current batch pyrolysis process is complete.
The workflow of a batch waste tire plastic to oil pyrolysis production line is as follows:
DOING batch pyrolysis plant workflow
1. Feeding Stage: Raw materials (such as waste tires or plastics) are fed directly into the pyrolysis furnace via a hydraulic feeder or after crushing. This stage typically requires no complex pretreatment; the feeding process is automated and takes approximately 2 hours.
2. Pyrolysis Reaction Stage: The pyrolysis furnace is heated in an oxygen-free environment, with the temperature gradually increasing.
①Initial Stage (0~100℃): The temperature is slowly increased, and air is expelled from the furnace to create an oxygen-free environment. The raw materials begin to absorb heat, and the pyrolysis process starts.
②Intermediate Stage (150~380℃): Rubber or plastic macromolecules are pyrolyzed into smaller hydrocarbon molecules, producing gaseous products. These products are separated from impurities by a gas separator and then enter the cooling system. Non-condensable gases are reused as fuel, while oil is temporarily stored for further processing.
③Isothermal Reaction: Maintaining a high temperature ensures a complete reaction, typically lasting at least 2 hours.
3. Cooling and Product Collection: After the reaction, heating is stopped, and the furnace body is cooled by fans. When the temperature drops to around 50°C, carbon black or solid products can be collected. DOING intermittent equipment is equipped with multiple cooling fans for rapid cooling and can be equipped with a patented negative pressure device as needed to promote oil-gas conversion and prevent flash explosions, ensuring greater safety.
4. Slag Removal Stage: After the furnace body cools to 35-45°C, steel wire or residue is discharged through an auger device. Exhaust gas is discharged after dust removal treatment. This stage requires manual operation, and the equipment must be cooled before starting.
5. Exhaust Gas Purification: Non-condensable combustible gases generated during pyrolysis are treated by a purification device and can be used to reheat the reactor, saving energy input costs. Waste generated from heating and combustion can be treated by desulfurization and denitrification devices to meet emission standards.
Pyrolysis tire plastic to oil and carbon black production line
Through the working process, batch pyrolysis production line can recycle waste tire/plastic into fuel oil, carbon black and steel wires(only for tires) through thermal pyrolysis technology, achieving waste to energy conversation.
