The invention provides a device for hypoxia pyrolysis treatment of combustible refuses using slot-type solar energy. Heating distillation is carried out on the refuses in an oxygen-free or oxygen deficient condition by using the thermal instability of organic matters in refuses, so that the organic matters generate splitting decomposition, and various new gas, liquid and solid is formed after condensation. A paraboloid slot-type reflecting mirror (2) supported by a ground bracket reflects the sunlight of the sun (1) to a solar energy vacuum pyrolysis pipe (3), the refuses which are fed into the solar energy vacuum pyrolysis pipe (3) by an auger (4) are heated, the hypoxia high-temperature pyrolysis of the refuses is realized, and refuse products are fed into a pyrolysis product separator (6) along a pipeline (5) for gas-solid separation. Pyrolysis gas products are elicited by a gas elicitation pipeline (7), and pyrolysis solid products are elicited by a solid elicitation pipeline (8).
