Dual-layered Filter Granule Bed Dry Fuel Gas Desul

Product Description: GBP from the bed, bed dust particle filter based on the GBF evolved. Details:The basic principle is: GBP alkaline desulfurization agent is injected into the upstream pipeline, together with the flue gas into the GBP, when the flue gas through the filter layer, the desulfurization agent powder along with the dust GBP captured at the same time, SO2, HCl, HF and other acid gases captured in the filter layer in the alkaline desulfurization agent absorption removal to achieve integration of desulfurization dust.Depending on the flue gas temperature conditions, using different alkaline desulfurization agent:1. For the low-temperature flue gas (<200 ), could gas spray cooling to 65 80 (above the dew point temperature of 15 20 ), spray-dried lime powder Ca (OH) 2 deacidification. Dechlorination rate of 95%, desulfurization rate was 85%.2. For the 200 400 flue gas can be sprayed NaHCO3, dechlorination rate of 95%, desulfurization rate was 85%.3. For the 400 700 flue gas can be sprayed Ca (OH) 2, dechlorination rate of 95%, desulfurization rate was 85%.GBP gas purification processes, systems simple, investment and low operation cost, less water, desulfurization ash-free dry row, easy handling, no waste water, particularly suitable for municipal solid waste incinerator, medical waste incinerator flue gas purification, is also suitable for need to deacidification of the kiln dust flue gas purification.
