Abstract

An integrated dusting-desulfurizing system is composed of a dusting unit with liquid inlet, overflow apparatus, dewatering plate, flow guiding plate, liquid collecting hopper and blow-out outlet, a desulfurizing unit, a dewatering-defogging unit, and a circulation sprinkling unit with sprinkling head extended into desulfurizing cylinder and dusting unit. Its advantages are high dusting and desulfurizing effect (99.5%) and low cost.

Description

technical field [0001] The invention relates to an integrated system of dust removal and desulfurization, in particular to an integrated system of dust removal and sulfur dioxide treatment for flue gas discharged from coal-fired boilers in power plants, metallurgy, chemical industry, medicine, casting and so on. Background technique [0002] With the rapid economic development and social progress, various industrial dust and SO 2 Emissions are increasing day by day, which is bound to cause serious pollution to the environment. Dust causes environmental pollution, SO 2 Acid rain is produced, causing great harm to buildings and crops. [0003] At present, most of the dust removal and desulfurization devices on the market are electric dust removal and single cyclone dust removal. Can not make dust and SO 2 processing is performed synchronously. Even if some dust removal devices are equipped with desulfurization equipment, calcium should be added to the furnace, but the eff...
