Embodiment Construction

[0016] Among the figure "1"; the air blown by the blower fan "2" is delivered to the heat carrier particle heating furnace "1" by the air heater "3", and burns with the combustible gas introduced by the gas delivery pump "15". The heated heat carrier particles are sent to the cyclone separator "4", and the gas and particles are separated. Its hot air is sent to air heater "3" and nitrogen heater "13" for heating the gas. The hot carrier particles enter the upper part of the fluidized bed cracking furnace "6" through the valve "5". The biomass particles are blown from the biomass hopper "7", through the screw feeder "8", and the nitrogen gas flow heated by the nitrogen heater "13". It is ejected from the biomass particle nozzle "18" and mixed with heat carrier particles. Enter fluidized bed cracking furnace " 6 " under the effect of air-flow, spray into the raw material guide rail " 22 " upper end entrance that the inner wall of garden cylinder is installed. Biomass and heat...

Abstract

The invention relates to a method for preparing biofuel oil using crop straws and brushwoods by thermal cracking, in particular to a thermal chemical cracking technology. The method comprises a heat carrier particle heating furnace 1, a cyclone separating device 4, a single-spiral feeder 8, a condenser 11, a fluidized bed cracking furnace 6, a gas-carbon separator 9 and a gathering tank 12. The method has the advantages that: a process system of the invention is suitable for completing thermal cracking and condensing process within 0.5 second, so output capacity of biological oil is high and can reach over 67 percent; and the system adopts a closed loop, residual combustible gas and residual heat can be reused to heat carrier particles, so the method can save energy to reduce cost.

Description

Technical field: [0001] The invention relates to a method for preparing biofuel oil by thermal cracking of crop straws and firewood, in particular a method for preparing biofuel oil by thermal chemical cracking. technical background: [0002] Existing technology: crushed biomass straw particles are input into a cylindrical combustion chamber for oxygen-avoiding combustion, and the heating rate is slow, and the gas is cooled to become bio-oil, and the residual gas is emptied. Its disadvantages are: the yield rate of bio-oil is low and the remaining energy resources are wasted. Invention content: [0003] The purpose of the present invention is to improve the fluidized bed cracking furnace, which is suitable for completing the thermal cracking and condensation process within 0.5 seconds. Therefore, the yield of bio-oil is high, which can reach more than 67%. For the remaining combustible gas and waste heat, the system adopts a closed loop, and then uses the heating carrier...
