Abstract

The invention relates to a system for preparing activated carbon or bio-oil by fast activation or fast pyrolysis of biomass. The system comprises a feeding system, a pyrolysis reactor and a heating device thereof, an activated carbon / biochar collecting system, a spraying condensation system, a fluidization gas circulation system and a control system which are connected in sequence. The feeding system comprises a vacuum material-sucking machine, a weighing device and a material storage tank which are communicated with each other in sequence. The activated carbon / biochar collecting system comprises a cyclone separator and a carbon collecting box. A discharging outlet of the pyrolysis reactor is connected with a feeding port of the cyclone separator. The spraying condensation system comprises a spraying condenser, a heat exchanger and a circulating pump. An outlet of the cyclone separator is connected with an air inlet of the spraying condenser, and the fluidization gas circulation system comprises a circulating fan, a control valve and a flowmeter. The system for preparing activated carbon or bio-oil by fast activation or fast pyrolysis of biomass can be applied to fast activation of biomass to prepare the activated carbon, and the activated carbon with a high specific surface area is prepared; the system for preparing activated carbon or bio-oil by fast activation or fast pyrolysis of biomass can also be used for fast pyrolysis of the biomass to prepare the bio-oil, and the production cost is reduced.

Description

technical field [0001] The invention belongs to a biomass pyrolysis device, in particular to a system for rapidly activating or fast pyrolyzing biomass to prepare activated carbon or bio-oil. Background technique [0002] As a renewable resource, biomass is of high value when converted into activated carbon for adsorption material, biofuel for fuel, and combustible gas. Biomass pyrolysis has always been a research hotspot of scholars at home and abroad. Biomass pyrolysis is generally divided into slow pyrolysis and fast pyrolysis. Slow pyrolysis is generally for the purpose of preparing activated carbon, while fast pyrolysis is for the purpose of preparing bio-oil. Activated carbon is a carbon material with a well-developed pore structure. Because of its large specific surface area, rich surface functional groups, and strong adsorption capacity, it is widely used in medicine, environmental protection, food, electronics, chemical industry, agriculture, national defense and o...
