AI Technical Summary
In existing technologies, the mixing uniformity between the denitrification solution and the flue gas is insufficient, resulting in incomplete denitrification reaction and affecting denitrification efficiency.
A high-efficiency HSNCR denitrification device was designed, comprising a support plate, a fixed plate, a first denitrification mechanism, and a second denitrification mechanism. The support pipe and spray pipe are rotated by a motor to achieve uniform spraying of the denitrification solution, and a filter plate is used to prevent nozzle clogging.
It improves the efficiency of flue gas denitrification, ensures uniform spraying of denitrification solution, avoids nozzle clogging, and enhances the overall denitrification effect.
