The invention provides low-energy consumption household refuse high-pressure extruding and dry-humidity separating equipment and method. The equipment comprises steps of a feeding hopper, an extruding cavity, a dry material discharging port, a humid material discharging port, a rack, a primary extruding mechanism, a secondary extruding mechanism, a gate mechanism, a hydraulic station and an electric control system. An extruding process can be divided into a primary pre-extruding section and a secondary main-extruding section; by the use of a pre-extruding head locking device, secondary main-extruding can be conducted without a stop after the primary pre-extruding work is finished; the secondary main-extruding section can be divided into a differential extruding stage, a high-pressure extruding stage and a high-pressure maintaining stage; after the main-extruding is completed, a main extruding head is driven by a layout oil cylinder mounted on a main extruding head structure to push material; and a primary extruding head and the secondary extruding head can work at the same time after the main extruding is completed and do not intervene each other. The separating equipment has short extruding stroke, compact extruding process and high work efficiency, so equipment energy consumption can be greatly reduced.
