A household refuse gasification pyrolysis treatment device for saving energy and decreasing energy consumption, comprising a gasification system (1), a pyrolysis system (2), and a gasification agent supply unit and water tank (3). The gasification system (1) and the pyrolysis system (2) connected to each other are used. The syngas generated by the gasification system (1) is used for providing the energy required for pyrolysis, thereby reducing energy consumption, simplifying the structure of the device, and improving the treatment efficiency of the entire system. A closed circulation system has a higher safety and environmental protection index.
