The utility model relates to a vertical pyrolysis reactor. The vertical pyrolysis reactor comprises a reactor shell, a feed device, a biomass gas outlet which is arranged on the top of the reactor, an ash discharge device at the bottom of the reactor and a grate inside the reactor, wherein the feed device is positioned at the bottom of the reactor, and the discharge port of the feed device is positioned in the center of the bottom inside the reactor. By adopting a mode of feeding in the center of the bottom of the reactor, the problem of uniform distribution which is one of three bottlenecks troubling a biomass pyrolysis reactor for a long time can be solved; a slag crusher is arranged in the pyrolysis and can be organically combined with a rotating grate, the output can be accurately regulated according to the running speed of the grate, and a pyrolysis reaction can be accurately controlled by controlling the feed speed, the discharge speed, the material layer thickness, the air input, the air inlet distribu
