REFORMING APPARATUS AND METHOD OF SYNTHESIS GAS FROM BIOMASS

PURPOSE: A reforming apparatus and a reforming method of biomass syngas are provided to effectively aspirate syngas and remove tar with a relatively low cost and low power. CONSTITUTION: A reforming apparatus of biomass syngas comprises a gasification unit(100) which combusts biomass inserted from the upper part, and discharge ashes to the lower part and syngas to upper part; a heat exchanger(200) which cools syngas; a reforming unit(300) which separates tar and carbon dioxide contained in the syngas and removes tar by mixing circulating sealing water and cooled syngas; and a water sealing vacuum pump(400) which mixes syngas with sealing water by vacuum sucking cooled syngas while circulating the sealing water. The reforming unit comprises a first tank with an inner space which removes tar contained in syngas by cooling the mixture of syngas and sealing water, and discharges the rest components of syngas with tar removed to the upper part and the sealing water containing carbon dioxide to the low part; and a second tank(320) which an inner space that separates and discharging the outside air and carbon dioxide to the upper side by flowing in the outside air and cooling the sealing water containing carbon dioxide, and discharges the rest components of the sealing water to the water sealing vacuum pump. The first tank comprises a first case(312) equipped with a first sealing water outlet port and a porous plate(314) equipped within the first case so that the mixture is able to be injected to the bottom surface uniformly.
