Implementation process
(1), main reactor is three-conical double water innercooling biomass flash-cracked heating of producing the bio-fuel-oil reactor, makes oil fuel burner 7 work, the boosting of carrying out in order to guarantee when the initialization temperature in the main reactor to reach technological temperature rapidly;
(2), supply with water coolant through axle cooling water inlet pipe 11: flow is 0.8L/s, adds water coolant to feed-pipe water-cooled tube 21;
(3), start to change awl 2: when reactor temperature reaches 550 ℃, starter motor 14, motor 14 drives axle 9, changes awl 2 and awl cap 17 rotates through chain and sprocket wheel 10;
(4), start heat carrier recirculation system: thermal barrier is circulated;
(5), the oxygen in the scavenge system: feed nitrogen 3min
(6), feeding: 10kg/h; Thermal barrier is entered commentaries on classics awl bottom through three heat carrier current inget pipes 18, biological particles is also entered by feed-pipe 20 changes the awl bottom, under the effect that awl cap 17 rotates, biological particles is to mixing rapidly with thermal barrier in the shunting all around, and is under the centrifugal action that changes awl 2, up like spiral along the commentaries on classics conical surface then, in this process, biological particles is heated and the flash thermo-cracking takes place, and the steam that pyrolysis forms enters condensing tower by escape pipe 4, makes bio-fuel-oil; Part does not have complete pyrolytic biological particles and portion of hot carrier to enter double-deck fixed cone interlayer under the effect of changeing the awl upper edge, flows to the awl end again to participate in reaction again.And the thermal barrier that is thrown out of is collected 13 outflows of thermal barrier outflow pipe by heat carrier flow concentration plank 5, enters the thermal barrier Pneumatic conveyer, carries out recycle.The placement of fixed cone 3 is in order to reduce the parking space of pyrolysis steam in reactor, and fixed cone 3 can be adjusted with rotary handle 19 with the spacing of changeing awl 2; 1 of riot gear is to cause that in order to prevent the pyrolysis steam from not derived rapidly for some reason the main reactor internal pressure increases the generation that causes the problem of exploding; 21 of charging cooling tubes are in order to prevent that biological particles from just the burnt cooling provision of sticking with paste charing and taking taking place before entering rotation awl bottom; Gas burner 12 is in order to make full use of the energy the not condensable gases of coming out in the condensing tower to be drawn back main reactor to burn and utilize, to reduce the biomass fuel production cost;
(7), stopped reaction: stop heating, stop feeding, stop to change awl and delivery system, close water coolant;
(8), collection of biological fuel oil from condensing tower;
(9), cleaning system.
