The waste pyrolysis production line has several important components. It is composed of feeding system, pyrolysis system, oil separating and cooling system, non-condensable combustible gas (NCG) scrubbing system, flue gas purification system, discharging system, circulating water cooling system and electrical control system.
The raw material is automatically transported to the transitional hopper through the feeding conveyor. This system can also realize on-line weighing, conveying, feeding seal and other functions.
Feeding System
Pyrolysis system is the core system of all kinds of industrial continuous pyrolysis plant. In the oxygen-free or oxygen-poor environment , the pyrolysis system function is to complete the pyrolysis reaction of organic waste or hazardous waste and convert the raw material into fuel oil, NCG and solid output under normal pressure, low pyrolysis temperature or catalyst action.
Pyrolysis System
The main function of NCG scrubbing system is to remove the acid components in NCG, such as hydrogen sulfide.
NCG Scrubbing System
This main function is to cool the outputs from pyrolysis system and flue gas by using water as cooling medium. The cooling water is circulated in the way of in-direct heat exchange, which does not contact any material directly, and there is no waste water generated.
Circulating Water Cooling System
This system is to cool the gas phase output from pyrolysis reactor to a safe temperature and separate them according to the different boiling point. After cooling down, the condensed liquid oil with high boiling point will be temporary stored in the oil gathering tank and then be transported to the oil tank farm by liquid pump. The NCG with low boiling point will be transported into the NCG scrubbing system.
Oil Separating and Cooling System
The main function of discharging system is to complete the discharge sealing, cool and convey the solid output.
Discharging System
This main function is to cool down and purify the flue gas. Through multi-stage purification and comprehensive treatment, the harmful substances in the flue gas can be removed, the flue gas discharged into the atmosphere can meet the most strict national environment standards. This is a key factor to ensure the operation of the production line.
Flue Gas Purification System
Electrical control system adapts PLC/DCS control system to automatically control the control points. It also has the function of date collection, calculation, record, printing record, safety alarming and other functions.
