Description

technical field [0001] The invention belongs to the field of flue gas denitrification equipment, in particular to an ozone denitrification pre-spray absorption device. Background technique [0002] Nitrogen oxides are generally recognized as one of the three major air pollutants (namely soot, sulfur dioxide, nitrogen oxides), and its harmfulness is even worse than that of sulfur dioxide, and even deeper. With the development of the economy, it is urgent to effectively control the air pollution caused by coal combustion, especially the control of nitrogen oxides in the process of coal combustion, flue gas denitrification technology is very important. At present, the common flue gas denitrification technology can be roughly divided into two categories, one is to control the generation of NOx in the combustion process, that is, low NOx combustion technology (LNBs); the other is to process the generated NOx, that is, flue gas denitrification technology. Among them, the traditio...
