Oily sludge is the oily solid waste produced in the process of oil exploration, exploitation, refining, tank cleaning, storage and transportation, and oily sewage treatment. After years of research and development, we have developed a complete set of high-efficiency and low-cost oily sludge treatment technology and equipment. This technology can effectively realize the "reduction, recycling and harmless" of oil sludge. It has the characteristics of fast heating speed, uniform heating, high energy transfer efficiency and no secondary pollution. After the oily sludge is treated, the oil can be recycled as a resource to increase economic benefits. The tail gas is discharged through the flue gas purification system, and the mineral oil content in the sludge is less than 3000mg / kg, It can be used as soil and adsorbent for landscaping. The treatment process of the device is clean and does not need to consume any fossil fuel, so as to avoid secondary pollution. Moreover, the operation process of the device is normal pressure, which eliminates the safety risks of high pressure explosion and easy to hurt people of conventional technology. Oily sludge treatment device can be widely used in oil exploration, oil transportation, oil refining, oil field sewage treatment process of tank bottom sludge, ground sludge, refining sludge, suspended solids sludge, as well as all kinds of oily sludge produced by large-scale machine repair plant, whether aging sludge or fresh sludge can be treated to the discharge standard of agricultural sludge.
