Summary of the invention
The purpose of this utility model is to provide a cover circulating fluidized bed high temperature ash pyrolysis coal system oil device, is thermophore with the high-temp circulating ash of circulating fluidized bed, and the fast pyrogenation coal is produced liquid oil, produces the inflammable gas and the semicoke of part simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is: circular fluid bed high temperature ash pyrolysis coal system oil device, comprise circular fluid bed, pyrolysis reactor, cyclonic separator A, high temperature is got apparatus for ash, coal dust disconnecting gear, the coal dust entrance lock, helixes feed equipment, cyclonic separator B, the Venturi spray cooling device, fluid collection device, solid biologic charcoal and circulating ash send-back device, water circulating pump, suction fan, coal bunker, screw feeder, rotary pocket feeder, the fan mill, wherein, apparatus for ash is got by high temperature respectively in the top of pyrolysis reactor to be connected with the bottom straight length of cyclonic separator A, be connected with coal dust disconnecting gear by the adjustable speed helixes feed equipment, the top outlet of pyrolysis reactor is connected with cyclonic separator B, and the outlet at bottom of pyrolysis reactor is provided with solid biologic charcoal and circulating ash send-back device.The lower end of coal bunker is provided with screw feeder, connects coal dust disconnecting gear by transport pipe and through rotary pocket feeder, fan mill.Be provided with baffle in the pyrolysis reactor.The solid biologic charcoal is connected with the grey backpass ductwork of circulating ash send-back device with cyclonic separator B lower part outlet and circular fluid bed.The bottom of coal dust disconnecting gear is provided with the coal dust entrance lock.
The heat that this device pyrolysis of coal 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 coal dust, realize being rapidly heated and pyrolysis of coal, make coal discharge volatile matter, 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 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 liquid 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 coal dust of circulating ash to produce liquid oil and inflammable gas, not need extra thermal barrier.
(2) directly loopback boiler combustion of pyrolysis product noncondensable gas and solid semicoke.
(3) high temperature ash and coal dust 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 regime.
(4) complete assembly does not have complex component, and is simple, is easy to amplify and industrial application.
