[0106] refer to Figure 12 As shown, the pine sawdust raw material (V ad =73.88%, Q net,ar =18.41MJ / kg) stored in the raw material bin 1, transported to the drying bin 2 by belt transmission for drying treatment, reducing the moisture content in the pine wood chips, and then transported to the biomass and catalyst mixed feeding device through the biomass feeding device 3 5 is mixed with the catalyst and sent to the moving bed pyrolysis reactor 6, and the radiant heating tube 18 on the moving bed pyrolysis reactor is used to radiate and heat the mixed material to cause catalytic pyrolysis reaction (500-750°C), and the oil gas produced The mixture (500-600°C) enters the high-temperature dust collector 7 through the top pipe of the reactor for particle dust removal, and then enters the oil-gas cooler 8 to cool down. After separation, biomass oil and pyrolysis gas are obtained respectively, and the pyrolysis gas then enters the pyrolysis gas for purification The net pyrolysis ga...
