The invention relates to a method for simultaneous desulfurization and dechlorination of blast furnace gas. The device used includes a desulfurization adsorbent injection device and a dechlorination agent injection device. The inlet downcomer of the dust collector is sprayed with ultra-fine powder desulfurization and dechlorination agent, making full use of the temperature, pressure and other working conditions at this point to form a simultaneous desulfurization and dechlorination process suitable for blast furnace gas source treatment. Specific limitations have solved the problems of life, efficiency, pressure drop, and waste water faced by blast furnace gas fine desulfurization. On the premise of ensuring the desulfurization rate, the consumption of water resources has been reduced, and the amount of solid waste has been reduced. The problem of low space velocity and large floor area has truly achieved the source control of blast furnace gas. |
