Beston plastic pyrolysis plants mainly inlcude batch operation, semi-automatic and fully continuous operation. And the continuous pyrolysis plant is relatively popular among them.
The design of continuous plastic pyrolysis plant mainly includes the following parts:
Moving horizontal pyrolysis reactor; Hot air circulation heating system; Oil gas filter; Spray cooling system; Secondary fire retardant damper; Strong spray dedusting system; Oil gas recycling system; Feeder system; Discharging system; Pressure and temperature multipoint monitoring system; Central electric control system.
Compared with the burning furnace, the continuous pyrolysis plant has small size, small floor area, simple operation, less operator, to a large extent, it can save the operating costs.
Beston continuous waste plastic pyrolysis plant adopts the screw feeding sealing system technology, which is hold by the company’s invention patents, hot air heating furnace circulating heating technology, heat drying technology with high heat exchange efficiency and capacity. Impeccable electrical control system save labor costs. Three waste utilization reasonable recovery can basically realize of zero emissions, safety and environmental protection.
Beston continuous pyrolysis plant produces some gas, the pyrolysis gas is enough to meet the needs of device self-heating, additional fuel consumption more less, this plant can use own end products of oil as a recycled energy heating for the whole process.
Introduction of continuous pyrolysis process:
Pretreated plastic(can be also rubber, oil sludge, medical waste) will be conveyed to the moving horizontal pyrolysis reactor through feeder system, then it starts to pyrolysis and oil gas will be generated when temperature up to 500 degrees. Then the oil gas will be cooling down by spray cooling system, it would be liquefied, go into the oil tank. And at the same time, some uncondensed gas come into hot air circulation heating system by secondary fire retardant damper, it will be recycled for heating reactor as gas material. Exhaust gas go to the strong spray dedusting system for removing pollution, then let environmental gas go to the air. The pyrolysis slag emissions and recycled through second sealed discharging system.
The pyrolysis oil can be directly used as the fuel oil for ship, and it can be further classified and processed, then formation of oil products such as petrol, diesel with high benefits.
The pyrolysis ash can be used as ingredients for building materials.
