The invention belongs to the technical field of garbage treatment, and particularly relates to a high-efficiency environment-friendly garbage pyrolysis process. A garbage pyrolysis device comprises anincineration chamber, a hot air chamber, a smoke discharge pipe, a slag collecting box, a garbage water recycling tank, an air conveying channel, an air conveying pipe, a partition plate, a combustion-supporting mechanism, a filter screen and a feeding port with a sealing cover; the hot air chamber is arranged on the outer side of the incineration chamber, a gas conveying pipeline is arranged onthe hot air chamber; the air conveying channel is used for conveying hot air for pyrolysis to the hot air chamber; the waste is compressed, punched and inserted into the sodium; the garbage pyrolysisdevice can tear the plastic film on the sodium when the waste pyrolysis device works, so that the sodium is in contact with the water in the garbage, a large amount of hydrogen is released, the hydrogen enables the garbage blocks to be opened, and hydrogen is ignited in the pyrolysis device, so that the interior and the exterior of the rubbish block are simultaneously combusted, so that the rubbish pyrolysis speed is greatly increased.
