Embodiment 1

[0055] A fast pyrolysis refinery with a capacity of 100Kg / h is used to process cotton stalks to refine bio-oil. A two-stage cyclone separator is used in the device to improve the classification effect of solid and pyrolysis gas.

[0056] Its specific process operation method is as follows:

[0057] Turn on the co-firing furnace, run the heating system, and set the heating temperature to 550°C. Turn on the Roots blower, open the valve in the connecting pipeline, run the fluidized gas circulation system, and set the circulation gas flow rate in the system to 20m 3 / h. Turn on the circulation pump of the condenser and the external condensate water circulation pipeline to run the condensate system. After the interior of the fast pyrolysis reactor is heated to the required set temperature, run the feeding system, set the frequency of the inorganic frequency modulation motor to 25Hz, and gradually feed the cotton straw particles with a moisture content of 8% and a particle size o...

Abstract

The present invention relates to an industrial continuous agricultural and forestry biomass fast pyrogenation oil refining method and a device thereof. The invention belongs to the technical field of biomass regeneration utilization and changing into energy. The crushed and dried agricultural and forestry biomass material is delivered into a pyrolysis reactor from the base for reacting. The carbon and pyrolysis are generated, wherein the pyrolysis enters a condenser along with the circulating gas. The bio-oil obtained after condensing the pyrolysis gas and incoagulable gas enter a reacting system for being heated by a combustion furnace for recycling. The fast pyrogenation oil refining method and the device of the invention use the incoagulable gas generated in the system as circulating fluidizing agent gas and heat supplying gas for high-efficiently executing the fast pyrogenation, gas-solid separation, condensing oiling of agricultural and forestry biomass and furthermore realizing the excellent circulation in the system. The device of the invention also has the advantages of reasonable structure of reactor, compact mechanism, stable operation of whole device, and suitability for industrial continuous production.

Description

technical field [0001] The invention relates to an industrialized continuous rapid pyrolysis oil refining method of agricultural and forestry biomass and a device thereof, belonging to the technical field of biomass regeneration and utilization and its energy conversion. Background technique [0002] Biomass rapid pyrolysis refining is a modern high-tech that efficiently utilizes agricultural and forestry biomass resources. Compared with traditional pyrolysis, it adopts ultra-high heating rate (10 2 -10 4 K / s), ultra-short product residence time (0.2-3s) and moderate pyrolysis temperature, so that the organic polymer molecules in the biomass can be quickly broken into short-chain molecules under the condition of isolating the air, so that coke and non-coagulation Gases are minimized, thereby maximizing the liquid product - bio-oil. Bio-oil is a brown-black viscous liquid with a calorific value of 20-22MJ / kg. It can be used directly as a fuel or refined as a substitute for...
