The invention belongs to the technical field of garbage disposal equipment, and particularly discloses a pyrolysis gasification furnace. The pyrolysis gasification furnace comprises a rack, a furnacebody, a furnace hearth, a secondary combustion chamber and a driving unit; the top of the furnace body is provided with a feeding port and a flue gas outlet, the bottom of the furnace body is providedwith a slag outlet, and the side wall of the furnace body is provided with a plurality of furnace doors and a plurality of observation holes; a rotatable furnace grate unit is arranged in the furnacehearth and comprises a garbage dispersing cap, a plurality layers of garbage distributing grates and a garbage furnace grate body which are sequentially connected from top to bottom; the side wall ofthe furnace body comprises an inner-side refractory layer, an outer-side refractory layer and a heat preservation layer, and the secondary combustion chamber is arranged between the inner-side refractory layer and the outer-side refractory layer; and a decoking unit is arranged in the furnace hearth and comprises a plurality of scraper blades and a power mechanism used for driving the scraper blades to do rotating motion, and the scraper blades are circumferentially distributed along the central axis and attached to the upper surface of the garbage furnace grate body. According to the pyrolysis gasification furnace, the scraper blades are arranged to remove coked materials on the furnace grate, furnace grate blocking is prevented, normal working and running of the furnace grate are guaranteed, and garbage can be fully combusted.
Description
technical field [0001] The invention belongs to the technical field of garbage treatment equipment, and specifically discloses a pyrolysis gasifier. Background technique [0002] At present, the domestic waste treatment methods mainly include composting, landfill and incineration. Among them, the direct incineration of waste will produce a large amount of harmful gas dioxins, and the technology of waste pyrolysis and gasification can effectively overcome the dioxin pollution produced by waste incineration. Question, garbage pyrolysis gasification refers to the thermal decomposition of garbage under anaerobic or anoxic conditions to produce combustible gases (such as hydrogen, carbon monoxide, methane and other hydrocarbons, etc.), organic liquids (such as organic acids, tar, etc.) and charcoal The process of processing black and other substances has the advantages of harmless waste, reduction, recycling, small secondary pollution, and low concentration of dioxin emissions.
