Embodiment 1
[0039] refer to Figure 1~4 , a humidified flow equalization pre-charged particulate matter enhanced removal system, said system sequentially includes a droplet injection device 1, a current equalization device 2 combining flow blocking and diversion, and a charge enhancement discharge device 3 along the flue gas direction , the distance between the droplet spraying device 1 and the flow equalizing device 2 combining flow blocking and guiding is 1000 mm.
[0040] The droplet spraying device includes a nozzle 5 and a bracket 6, the bracket is arranged perpendicular to the direction of the flue gas, and parallel pipes 7 are installed on the bracket, and the nozzle 5 is arranged on the pipe 7; the pipe 7 is perpendicular to the smoke The gas direction is arranged, the distance between the pipes is not greater than the effective spraying distance of the nozzles 5, the spraying direction of the nozzles 5 is perpendicular to the smoke direction, the nozzles on a single pipe are even...
Embodiment 2
[0047] refer to Figure 2-6 , a humidified and even-flow pre-charged particulate matter enhanced removal system. According to the sequence of the flue gas flow, an ultra-fine droplet spraying device 1, a current-balancing device 2 combining flow blocking and diversion, and a charge-enhancing discharge device are respectively arranged. 3. The air flow first passes through the ultra-fine droplet injection device 1 and then through the flow equalization device 2 combining flow blocking and diversion. The distance between the ultrafine droplet injection device 1 and the flow equalization device 2 combining flow resistance and flow diversion is 500 mm.
[0048] The droplet spraying device includes a nozzle 5 and a bracket 6, the bracket is arranged perpendicular to the direction of the flue gas, and parallel pipes 7 are installed on the bracket, and the nozzle 5 is arranged on the pipe 7; the pipe 7 is perpendicular to the smoke The gas direction is arranged, the distance between ...
