Comparison of the advantages of high-ratio calcium hydroxide dry desulfurization and wet desulfurization
Author:
Wet desulfurization:
(1) Desulfurization wastewater produces secondary pollution, has a strong pungent odor, and sludge and wastewater require professional treatment; (2) Wet desulfurization wastes water resources, a large amount of water is evaporated into water vapor, condensation upon cooling produces white smoke and water droplets, causing "visual pollution" and gypsum rain, gypsum rain leads to corrosion of surrounding equipment and deterioration of the working environment; (3) Wet desulfurization has high installed power, high electricity costs, and high operating costs; (4) Desulfurization pools and desulfurization towers occupy a large area, the equipment is complex, and maintenance costs are high;
Dry desulfurization:
(1) No wastewater discharge; no sludge treatment; no odor, no secondary pollution; (2) Desulfurization agents and desulfurization by-products are both dry, the flue gas temperature is high, no condensation occurs, no white smoke, no corrosion, no water consumption, and the flue and chimney do not require anti-corrosion; (3) Dry desulfurization has low installed power, low electricity costs, and low operating costs; (4) Dry desulfurization equipment occupies a small area; the equipment is sophisticated; maintenance costs are low.
