Oily sludge pyrolysis treatment system and method

The invention discloses an oily sludge pyrolysis treatment system and method, and belongs to the technical field of oily sludge treatment. The system comprises a feeding and discharging system, a pyrolysis system, a washing and cooling system, a non-condensable gas treatment system and an oil-water storage system. In the working process of the oily sludge pyrolysis treatment system, not only can non-condensable gas evaporated from the oily sludge be used as fuel to recover part of petroleum resources in the oily sludge, but also moisture and oil in the oily sludge material can be almost completely removed after treatment, and the moisture and the oil can be reduced by more than 50%-60% generally; the oily sludge treatment system is simple in structure and convenient to operate, realizes comprehensive utilization of reduction and recycling of oily sludge, is also provided with a treatment device for coping with emergency working conditions, can cope with various sudden conditions, and also has the advantages o
