Oil Sludge Pyrolysis Process
Sludge Pretreatment: First, the sludge is pretreated, including dehydration, impurity removal and other operations. Thereby improving the pyrolysis efficiency and equipment operation stability.
Pyrolysis Reaction: The pretreated sludge is sent to the pyrolysis reactor and undergoes pyrolysis reaction under the set temperature and atmosphere conditions. The pyrolysis reactor adopts indirect heating. In order to avoid direct contact of the sludge with the flame, which may cause local overheating and incomplete reaction.
Product Separation and Collection: The gaseous products produced by pyrolysis can be recycled as fuel gas after cooling and purification. The liquid products can be separated by processes such as distillation to obtain fuel oil of different qualities. The solid residue can be used to manufacture building materials or landfill after screening, magnetic separation and other treatments.
Tail Gas Treatment: The tail gas generated during the pyrolysis process contains a small amount of harmful gases and particulate matter. The tail gas needs to be strictly purified, such as activated carbon adsorption and catalytic combustion). It is discharged into the atmosphere after meeting the environmental emission standards.
