Abstract
Provided is a biomass syngas purification process under negative pressure for producing oil and the system thereof. In the process a high temperature syngas extracted from a gasifier enters a water cooled chilling tower via a water cooled flue and the gas is partly chilled to solidify slag by spraying water; the waste heat is recovered by a waste heat boiler of a water tube type and a waste heat boiler of a heat tube type in two stages with double pressure; the by products middle pressure steam and low pressure steam are ejected externally; after the heavy tar is condensed and recovered by the waste heat boiler of the heat tube type scrubbing and dust extraction by a Venturi scrubber without padding deep dust extraction by a wet electrostatic precipitator and purification by removing tar fog are performed; then the resulting product is extracted by a gas fan and sent to a wet gas holder for storage or supplied for use down stream. The purification aims of cooling of the syngas in stages gradient recycling use of waste heat dust extraction in steps and tar removal are achieved and the technical problems of a complex system long flow high energy consumption low efficiency and poor stability and economy are resolved by optimizing the process and controlling the appropriate process parameters.
