NOVELTY - A drive nozzle sucks dust containing gas (1) using jet of water droplets. A scrubber portion (4) cleans dust containing gas mixed with the water droplets. A suction tube (5) receives water flowing from the scrubber portion and stores water temporarily as circulating water. A discharge pipe (8) ejects circulating water with a circulation pump (7). A circulation line (9) circulates water through the drive nozzle.    USE - Dust removal apparatus for use in gasification system (claimed) for organic-type fuel and in liquid fuel synthesis system (claimed) used for manufacturing methanol and other fuels using biomass.    ADVANTAGE - Ensures efficient separation of heavy metal and cyanogen from the dust containing gas, by mixing the dust containing gas and the water droplets. Since the refinement degree of the gas is set high, enables manufacturing of fuels such as methanol with high yield.    DETAILED DESCRIPTION - The drive nozzle sucks dust containing gas generated by a gasifier. The dust containing gas contains heavy metal or cyanogen. An annular shower is arranged in a top opening (10) of the suction tube. A bypass pipe (12) is arranged in the circulating line so that the circulating water is recycled as shower water. A liquid storage tank is arranged in the periphery of the suction tube. The water replenished to the liquid storage tank is supplied to a level tank (6). A branch drain pipe is arranged in the circulating line to eject water flowing from the suction tube. An acid supply unit is arranged in the level tank and/or the suction tube. An auto strainer is arranged in the circulation line, downstream of the circulation pump. INDEPENDENT CLAIMS are also included for the following:    (1) gasification system for organic-type fuel; and    (2) liquid fuel synthesis system.
