High-temperature ash cooling device of biomass gas making system

The utility model discloses a high-temperature ash cooling device of a biomass gas making system, which comprises a cooling chamber, a high-temperature ash cooling device and a high-temperature ash cooling device, the cooler comprises one or more groups of plate-shell type heat exchange structures arranged in the radial direction of the biomass ash cooling channel; the plate-shell type heat exchange structure comprises a cooling medium inlet pipeline, a cooling medium outlet pipeline and a plate-shell structure; the plate shell structure comprises at least two cold radiation plates which are arranged at intervals. Cooling flow channels which are communicated with the cooling medium inlet pipeline and the cooling medium outlet pipeline and allow cooling media to flow through are formed in the cold radiation plates, and a supercooling space which allows biomass ash to pass through and cools the biomass ash is formed between every two adjacent cold radiation plates. The plate-shell type heat exchange structure i
