Removing device and removing method for particulate pollutants generated by combustion of biomass fuel

The invention discloses a removing device and a removing method for particulate pollutants generated by combustion of biomass fuel. The removing device comprises a chimney, a wet-type electric dust remover, a smoke condenser, a wet-type ash remover, a spiral ash remover, a combustion chamber and a heating furnace shell. The wet-type electric dust remover is arranged in the chimney. The smoke condenser sleeves the chimney. The wet-type ash remover is arranged at the lower end of the chimney. The smoke condenser is connected with the upper end of the spiral ash remover. The combustion chamber and the spiral ash remover are arranged in the heating furnace shell. A feed port communicated with the inside and the outside of the heating furnace shell is arranged on the combustion chamber. Smoke contains a large quantity of steam after the biomass fuel combusts, the steam can be condensed to form a thin water film on the surface of a precipitation pole when the temperature of the smoke continues dropping, and a cooling water jacket is arranged on the outer portion of the precipitation pole, so that exhaust smoke temperature is reduced, and heat of the smoke is recycled; condensed water generated by condensation serves as a water source of the wet-type electric dust remover, so that a water adding device, a water spraying device and the like are omitted, and water pollution is reduced.
