Pyrolysis Equipment for Oil Sludge

The equipment is applicable to the harmless and reduced recycling of various oil sludge (hw08), such as oily contaminated waste, ground sludge, refinery sludge, tank bottom sludge, drilling debris, ground oil spill, etc. The oxygen-free pyrolysis technology is used to indirectly heat the oil sludge. In the anaerobic state, the carbon chain in the oil sludge breaks and decomposes into small molecules of hydrocarbons, carbon, hydrogen and oxygen, and finally generates pyrolytic gas and pyrolytic carbon. The non-condensable gas in the pyrolytic gas flows into the combustion chamber for combustion and heating after purification, pressure stabilization and other processes, and the condensable gas forms pyrolytic tar. On the premise of safety, environmental protection and stable operation, the oil sludge is finally transformed into pyrolytic tar, pyrolytic carbon and other main products through anaerobic pyrolysis technology and equipment, so as to realize the harmless and reduced recycling of oil sludge.

The complete equipment is mainly comprised of:

Pretreatment system, pyrolysis module, oil receiving module, non-condensable gas purification heat utilization module, flue gas treatment module and electrical control module.

Technical features:
Industrial continuity
The pyrolysis process truly realizes continuous feeding, continuous oil discharge and continuous carbon production. The whole production line adopts PLC / DCS intelligent control system, which can realize automatic control and linkage adjustment of control points. It has the functions of data acquisition, operation, alarm and automatic deviation correction, which greatly improves the industrial production efficiency and production safety.
Proprietary innovative technology
Using proprietary sealing technology, anti coking technology, step thermal strengthening technology, oil-water separation technology and non condensable gas pressure stabilization technology, many key problems of pyrolysis treatment are solved.
Strong technical applicability
It is widely applicable to the pyrolysis of paint residue, waste plastics, municipal sludge, industrial sludge, oil sludge, tire rubber powder and other materials. It is a more "energy-saving and carbon reduction" environmental protection process than direct incineration.
Energy conservation and environmental protection
After being purified and stabilized, the combustible gas produced by pyrolysis is used as fuel for the heating device, which reduces the fuel consumption and flue gas emission of the system. Compared with incineration power generation, pyrolysis can reduce carbon dioxide emissions and other toxic and harmful gas emissions by more than 90%, which is recognized as the most excellent disposal method with environmental protection indicators.
Good investment income
With less investment, small land occupation, friendly environment and high output value, it can be disposed on site. It is a rare investment project with excellent comprehensive benefits.
