The utility model provides a sampling device for a gas with high dust content. The sampling device comprises a sampling pipeline and a jet pump, wherein one end of the sampling pipeline is positioned in a smoke gas passage; the other end of the sampling pipeline is connected with the jet pump; an angle between an incident gas passage and an outgoing gas passage of the jet pump falls within a range of 90-180 DEG; and an angle between an injected gas passage and the incident gas passage is an acute angle or a right angle, so that dust in the smoke gas in the sampling pipeline passes through the jet pump with gas flow; therefore, a filtering device is not needed on the sampling pipeline during sampling the smoke gas. The sampling device for the gas with the high dust content, provided by the utility model, has the advantages of simple structure, small maintenance amount, low cost and so on.
