Abstract

The invention belongs to and relates to a flue gas emission purification device, in particular to low-temperature flue gas efficient desulfurization, denitrification and white smoke removal integratedequipment, which solves the technical problems in the background art, and comprises an equipment shell, the front end and the rear end of the equipment shell are respectively provided with a flue gasinlet and a flue gas outlet; wherein a cooling heat exchange device, a mixed oxidation device filled with a strong oxidant, a high-pressure atomization spraying device filled with alkali liquor, a condensation heat exchange device, an adsorption device and a heating heat exchange device are sequentially arranged in the equipment shell from front to back. The device is simple in process route, lowin investment cost, small in occupied area, simple and compact in structure, high in automation degree, high in removal efficiency, low in operation cost and high in applicability; the SOX and NOX removal efficiency is high, the colored smoke and rain treatment effect is good, and the requirements that desulfurization, denitrification and white smoke removal can be conducted at the same time through only one set of equipment, and finally environment-friendly ultra-clean emission is achieved are truly met.

Description

technical field [0001] The invention relates to a flue gas emission purification device, in particular to an integrated equipment for high-efficiency desulfurization, denitrification and whitening of low-temperature flue gas. Background technique [0002] The discharge temperature of flue gas produced by industrial boiler (kiln) furnace equipment in non-power industries (including: industrial boilers, glass ceramic furnaces, cement furnaces, iron and steel metallurgy sintering furnaces, cracking equipment for coking and petrochemical systems, etc.) is 110-300 °C , while the currently commonly used mid-temperature selective catalytic reduction denitrification technology (SCR) has an optimum operating temperature range of 280-420°C, and the selective non-catalytic reduction denitrification technology (SNCR) has an optimum operating temperature range of 850-1100°C. For non-power industries (including self-owned power plants) low-temperature flue gas SOX and NOX ultra-low emissi...
