상술한 본 발명의 바이오오일 가스화 시스템의 작용을 알아보면 다음과 같다.The operation of the bio-oil gasification system of the present invention described above is as follows.

먼저, 정량펌프(110)를 통하여 바이오오일을 가스화 반응기(120)로 투입하면, 바이오오일 가스화 반응기(120)는 정량펌프(110)에서 투입되는 바이오오일을 이류체 노즐(121)을 통하여 투입하여 산화제(180)와 함께 가스화 반응을 일으킨다.First, when bio-oil is introduced into the gasification reactor 120 through the metering pump 110 , the bio-oil gasification reactor 120 injects the bio-oil input from the metering pump 110 through the two-fluid nozzle 121 . A gasification reaction occurs together with the oxidizing agent 180 .

이후 바이오오일 가스화 반응기(120)의 가스화 과정에서 생성되는 입자상 물질이 싸이클론 집진장치(130)에서 포집된다.Thereafter, particulate matter generated in the gasification process of the bio-oil gasification reactor 120 is collected in the cyclone dust collector 130 .

싸이클론 집진장치(130)에서 포집되어 배출되는 합성가스를 분사층 증기 개질장치(140)에서 증기 또는 촉매를 사용하여 개질하여 고품질의 개질가스를 생성하여 열교환기(160)로 유입시켜 고온의 개질가스를 냉각시키는 과정을 수행한다.The synthesis gas collected and discharged from the cyclone dust collector 130 is reformed using steam or a catalyst in the spray bed steam reformer 140 to generate a high-quality reformed gas and introduced into the heat exchanger 160 for high-temperature reforming. The process of cooling the gas is carried out.

이때 steam generator(150)에서 분사층 증기 개질장치(140)로 steam을 공급하여 steam 개질과정을 거친 후 개질가스(Reforming gas)로 열교환기(160)로 배출하는 것이다.At this time, steam is supplied from the steam generator 150 to the spray bed steam reformer 140 , and after a steam reforming process, it is discharged to the heat exchanger 160 as reforming gas.

열교환기(160)에서 배출되는 냉각된 개질가스를 전기집진 장치(170)로 유입받아 입자에 전하를 부여하여 분진을 부착제거하는 과정을 수행하여 개질가스(G1)를 배출하도록 작동하는 것이다.The cooled reformed gas discharged from the heat exchanger 160 is introduced into the electrostatic precipitator 170 and an electric charge is applied to the particles to perform a process of attaching and removing the dust, thereby operating to discharge the reformed gas (G1).

다시 말하면 상술한 개질과정을 거친 개질가스(reforming gas)는 열교환기(160)와 전기집진 장치(170)를 통과함으로써 분진이 제거된 최종 개질가스(G1)가 배출되는 것으로, 이러한 개질가스(G1)는 합성천연가스, FT 디젤, 메탄올, 에탄올, 수소 또는 DME등의 고부가 합성연료 생산에 활용이 가능하다. In other words, the reforming gas that has undergone the above-described reforming process passes through the heat exchanger 160 and the electrostatic precipitator 170 so that the final reformed gas G1 from which dust has been removed is discharged. ) can be used in the production of high value-added synthetic fuels such as synthetic natural gas, FT diesel, methanol, ethanol, hydrogen or DME.
