Sub-Systems
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.
-
01
Feeding
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.
-
02
Pyrolysis
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 pyro oil, NCG and solid output under normal pressure, low pyrolysis temperature or catalyst action.
-
03
NCG scrubbing
While to remove the acid components in NCG, such as hydrogen sulfide, the pressure is also maintained within a reasonable range through the NCG scrubbing system and further supply energy to downstream.
-
04
Circulating water cooling
The main function of this system is to cool the outputs from pyrolysis system and flue gas with 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’s no waste water generated.
-
05
Oil separating and cooling
This system is to cool the gas phase output from pyrolysis reactor to the safe temperature and separate them according to the different boiling points.
-
06
Discharging
The main function of discharging system is to complete the discharge seal, cool and convey the solid output.
-
07
Flue gas purification
The main function of this system 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, and the flue gas discharged into the atmosphere can meet the emission standards in various countries and regions.

08
Electrical control
Electrical control system adapts PLC/DCS control system to automatically control the control points. It also has the functions of date collection, calculation, record, printing record, safety alarming etc.
