| description | The invention provides a smoke gas demercuration method and device. According to the method, a demercuration catalyst and flue jet adsorption agent cooperated technology is used for efficient demercuration, wherein a demercuration catalyst layer is arranged at the upper stream of a denitration and ammonia spraying grille or/and the lower stream of the smoke gas denitration catalyst layer; adsorption agents are sprayed in the upper stream flue of a dust removing device; most Hg in the smoke gas is converted into Hg under the effect of the demercuration catalyst and is sufficiently and uniformly mixed with the adsorption agents entering the smoke gas through spraying; reaction adsorption is performed; then, the adsorbed mercury is removed along with particle materials in the dust removal equipment; the unadsorbed mercury is further adsorbed in the absorption device, so that the mercury in the smoke gas can be effectively controlled. The smoke gas demercuration method provided by the invention has the advant |
