Biomass charcoal, heat and electricity triple production system

The invention discloses a biomass charcoal, heat and electricity triple production system, which comprises a gasification furnace system, a gasification tank, a waste heat recovery device, a sawdust drying system, a bar maker system and a purification and cooling system. The gasification furnace system is composed of a refractory and heat-insulating material, and the gasification furnace system is divided into a preheating zone, an ignition zone, a high temperature zone, an annealing zone and a cooling zone. The gasification tank is used for holding machine-made sawdust bars. The sawdust drying system comprises a rotary drying furnace and a cyclone separator. The bar maker system comprises a bar making machine, a loading machine, a machine-made sawdust bar transporting machine, and a robot arm automatic loading machine. The purification and cooling system comprises a first-stage water-cooling spray dust removal device, a second-stage spray tower device and a water-cooling fan. In comparison with a conventiona
