Abstract

A process for dedusting and desulfurizing fume at the same time includes such steps as granulating the mixture of catalyst, desulfurizing agent and water-bearing agent, moistening and activating by high-temp. steam, reaction and adsorption in fume and pre-reacting chamber, entering bag-type deduster along with fume to generate a granule layer on the filter material, further removing dust and adsorbing SO2, and feeding the dust in ash cabin back to the circulating ash cabin for cyclic use. Its advantages are high efficiency, and synchronization of dedusting with desulfurizing.

Description

technical field [0001] The invention discloses an integrated method for flue gas dust removal and desulfurization and a device for realizing the method, belonging to the technical field of flue gas purification. Background technique [0002] Flue gas dust removal and sulfur dioxide removal are two key aspects of controlling environmental pollution. However, the dust removal and desulfurization technologies in the existing technology are often undertaken by two independent systems. Although there are many literature reports on the integrated technology of desulfurization and dust removal, such as "Boiler Dust Removal" in the sixth issue of "Metallurgical Energy" in 2000 Development and Application of Desulfurization Double Purification System", but its practicability and technical limitations are obvious. The reasons are, firstly, the dust removal efficiency is difficult to guarantee, especially the capture rate of fine particles is low; secondly, the system operation reliab...
