Abstract

A biomass carbonization and gasification method and a device are provided. The method comprises such technology processes as loading, heating and heat exchange, and also comprises carbonization and deep cooling. The carbonization and deep cooling are performed on a special carbonization and gasification device and the steps are that (1) the biomass entering the carbonization and gasification furnace such as straw is heated, carbonized, cracked and gasified; (2) heat exchange, deep cooling and decoking are carried out; (3) entering a gas storage tank for use. The device comprises a loader, a carbonization and gasification furnace, a high temperature heat exchanger, a heater and a deep freezer. The carbonization and gasification furnace adopts the semi-underground installation and is provided with a water seal tank on the bottom. The top of the carbonization and gasification furnace is arranged with the loader, the upper part of the carbonization and gasification furnace is connected with the high temperature heat exchanger, the deep freezer, a pressure automatic regulation valve, a fan, a gas holder and the heater in turns along the pipeline and the lower part is connected with thepipeline of the heater to form gas counter flow circulation circuit. The carbonization and gasification furnace is continuously added with the biomass such as the straw and the bottom end is arrangedwith a sludge drainer which is position in the water seal tank.
