AI Technical Summary
In existing boiler gas denitrification devices, the contact between the gas and the desulfurization and denitrification agent is insufficient, resulting in a reduced desulfurization and denitrification rate. Furthermore, after prolonged use, the flue gas is prone to clogging the filter screen, reducing the filtration efficiency.
A waste heat utilization boiler gas denitrification device is designed. A first rotary motor drives a turbulence box and a conical turbulence plate to extend the gas rise time. The rotation of the rotating tube and the turbulence box is achieved by the meshing of the first gear and the second gear, so as to achieve full contact between the flue gas and the denitrification agent. At the same time, the second rotary motor drives the cam to vibrate the filter plate to remove dust from the filter screen.
