PROBLEM TO BE SOLVED: To provide a dust removing device capable of refining an untreated gas to a clean gas, a gasification system of an organic-based fuel and a liquid-fuel manufacturing system capable of efficiently manufacturing a liquid fuel. SOLUTION: The dust removing device is constituted by using at least a first inner cylinder disposed in a water circulating tank receiving cleaning water from a jet scrubber cleaning the untreated gas and having an opening part at the upper end and a gap between at least part of the lower end and the bottom part of the circulating tank, a second inner cylinder disposed in the circulating tank so as to surround the first inner cylinder with the upper end placed at a lower level than the opening part of the upper end of the first inner cylinder and with the lower part kept in close contact with the bottom part of the circulating tank, a discharging pipe for floating separated components disposed in the first upper cylinder and discharging the floating components separated in circulating water in the first inner cylinder, and a discharging pipe for circulating water formed at the bottom part of the water circulating tank and forcedly discharging the circulating water in the water circulating tank.
