The invention relates to an energy-saving environmentally-friendly multifunctional heavy oil processing method, and belongs to the technical field of petrochemical engineering. The method is used for a heavy oil catalytic cracking device to save steam, reduce sewage and achieve propylene productivity and gasoline olefin reduction. A pre-riser, a lifting pipe reactor and a settling device are involved in the method, and the energy-saving environmentally-friendly multifunctional heavy oil processing method includes the steps of high-temperature catalyst entering, lifting, feeding and atomizing and anti-settling device coking, and is characterized in that fed materials are atomized by the adoption of technological media, and the technological media comprise C4-C6 olefin, catalytic gasoline, catalytic light gasoline, cocker gasoline, naphtha, dry gas and dry gas after hydrogen ethylene is removed; dry gas or dry gas after hydrogen ethylene is removed is used as rising media of the pre-riser; dry gas after hydrogen ethylene is removed is adopted as anti-coking gas of the settling device; or the technological media and steam are used in cooperation. A feeding nozzle, the pre-riser and a settling device anti-coking annular pipe are further involved in the method. The reactor can reduce the usage amount of steam and the amount of sewage, and has the functions of achieving propylene productivity and gasoline olefin reduction. The method is applied to the heavy oil catalytic cracking device.
