Document Type and Number:
WIPO Patent Application WO/2023/050700
Kind Code:
A1
Abstract:
Provided are a low-temperature desulfurization and denitrification method and system for flue gas of a cement plant. The low-temperature desulfurization and denitrification method for the flue gas of the cement plant comprises the following steps: reducing the temperature of flue gas discharged from a rotary kiln to 180°C-230°C; introducing the flue gas into a raw material grinding system; removing dust from the flue gas; reducing the temperature of the flue gas to below 20°C; introducing the flue gas into an adsorption tower for desulfurization and denitrification; and discharging the flue gas.
