Abstract

The embodiment of the invention discloses a device and method for removing sulfur and dust in lead-bearing flue gas. With a desulfurizing tower serving as the main body, the device includes a flue gas inlet, fiber woven layers, a lead dust storage bin, a gas equalizing chamber, a booster fan, a first filter layer, slurry nozzles, a steam separator, an electric dust remover, an induced draft fan, a chimney, a second filter layer, a circulating pump and a slurry circulation tank. The device has the advantages of high lead dust removal rate and desulfurization efficiency, continuity and stability of operation, and low operating costs, and can solve the problems of excessive lead and sulfur contents of flue gas and excessive lead content of desulfurization gypsum.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a desulfurization and dust removal device and method for lead-containing flue gas. Background technique [0002] Lead is a silver-gray metal with a high specific gravity (11.34) and a low melting point (327.1°C). As an extremely harmful heavy metal element, lead generally enters the body through the respiratory tract and digestive tract, causing damage to almost all organs. Physical development and intellectual effects are most severe; SO 2 It is a colorless gas with a strong pungent smell, easily soluble in blood and other viscous liquids of the human body, which reduces the immunity of the human body and weakens the ability to resist diseases. SO in the atmosphere 2 Can cause respiratory inflammation, bronchitis, emphysema, conjunctival inflammation, etc. According to the production characteristics of recycling plant enterprises, a large amount of high-temper...
