Bio oil manufacturing system comprising fluidized bed reactor and direct-contact heat exchanger for fast pyrolysis of biomass and method for manufacturing Bio oil using the same

摘要

The present invention relates to a bio-oil production system for producing a bio-oil by condensing gas produced by rapid pyrolysis of biomass into a quadrangular column shape having different lengths (x, y, z) A biomass feeder provided at one side of the fluidized bed reactor for feeding the biomass, a gas feeder for supplying the gas to the gas dispersion plate, A cyclone disposed on one side of the upper part of the fluidized bed reactor for discharging the char, a cyclone for receiving the pyrolysis gas of the biomass and recovering the pyrolysis gas contained in the pyrolysis gas, And a heat exchanger for condensing the bio-oil from the pyrolysis gas from which the pyrolysis gas is removed from the heat exchanger And a gas discharge pipe disposed at one side of the upper outer circumferential surface of the body, an injection nozzle installed at one side of the upper outer circumferential surface of the body to inject liquid into the body, A gas injection pipe having a tubular member penetrating through an upper surface of the body so as to be contained in the oil in the body and the other end fixed to the upper surface of the body; A pump which is connected to one side of the lower outer peripheral surface of the body and the other end of which is connected to the injection nozzle so that oil in the body is supplied to the upper part of the body; And a first filter installed at one side of the lower portion of the body for the rapid thermal decomposition of biomass It provides a bio-oil production system comprising a direct contact heat exchange reactor and the same layer. The present invention also provides a method for producing a bio-oil which comprises the steps of (a) supplying biomass to a fluidized bed reactor, supplying a high-temperature fluidized bed to the supplied biomass, and (B) heating the inner and outer portions of the fluidized bed reactor to rapidly pyrolyze the biomass after the injection of the hot gas into the fluidized bed reactor; and (c) (U / Umf) in the fluidized bed reactor is controlled by controlling the flow rate of the pyrolysis gas; (d) discharging the char generated in the rapid pyrolysis process; (e) (D) removing unfiltered microspheres using the cyclone; and (f) separating the pyrolysis gas removed in step (e) into a heat exchanger The gas which is condensed by direct contact with the oil inside the heat exchanger through the gas inlet tube to extract bio-oil, and the gas which is not converted into bio-oil is again supplied by the oil injected from the spray nozzle at the top of the heat exchanger Condensing and extracting the bio-oil; and (g) burning the condensed gas contained in the pyrolysis gas discharged through the cyclone through the sand and the fluidized bed reactor partially discharged from the fluidized bed reactor, In the step (f), the injection nozzle is supplied with the oil in the heat exchanger by using a pump, and a first filter is installed on a lower side of the heat exchanger so as to be located under one end of the gas injection pipe, And removing the fine particles in the spray nozzle to prevent the spray nozzle from clogging. / RTI
