Removing system for sintering fuel gas dioxin and method thereof

The present invention discloses a system for removing sintering fuel gas dioxin which comprises an adsorbent storehouse, a weight loss type metering micro-feeding apparatus, a spiral air-lock feeder and a loopback line. The present invention also discloses a method for removing sintering fuel gas dioxin. Active adsorbents in the storehouse is transported and sprayed to a main air-discharge flue through the feeding apparatus for absorbing the fuel gas dioxin, an electrostatic precipitator of a sintering machine is used to catch absorbed adsorbents which can be used as fuels to be transported to the sintering machine for burning through the loopback line and also can be used to oxidatively decompose the absorbed dioxin, and thereby efficiently removing the fuel gas dioxin and greatly reducing solid wastes containing dioxin caused by removing.
