The heat that biomass pyrolytic needs is provided by the accumulation of heat of circulating fluidized bed high temperature ash, by the direct contact heat transfer of high temperature ash with biomass material, can realize being rapidly heated and pyrolysis of biomass, make biomass discharge gas, the circulating ash of solid product and release of heat is then returned boiler by the spiral send-back device of reactor bottom.Gas enters cyclonic separator B and carries out gas solid separation subsequently, the solid loopback boiler after the separation, and clean gas then enters the rapid condensation device and carries out quick cooling, and gained liquid is bio oil, and noncondensable gas is then as combustion gas loopback boiler.So just realized effective utilization of pyrolysis product-gas, solid and liquid.
Advantage of the present utility model:
(1) can under the condition that does not influence the normal operation of circular fluid bed, utilize the heat thermo-cracking biomass material of circulating ash to produce the bio oil product.
(2) pyrolysis product does not coagulate inflammable gas and the directly loopback boiler combustion of solid biologic charcoal, substitutes the part fossil oil, save energy.
(3) high temperature ash and biomass powder enter in the pyrolysis reactor by helixes feed equipment respectively, can control the feeding coal of the two respectively, and then can regulate pyrolytic reaction and be in optimum state.
(4) complete assembly does not have complex component, and is simple, is easy to amplify.
