Abstract
The invention discloses a desulfurization and denitrification atomization spraying gun. The desulfurization and denitrification atomization spraying gun comprises a spraying gun body and a spraying head arranged at the front end of the spraying gun body. An ozone pipe for ozone to pass through is arranged inside the spraying gun body. The end and the tail of the ozone pipe are connected with the spraying head and an ozone supply device respectively. Drying and cooling gas surrounding the ozone pipe is injected into the spraying gun body. A rectangular nozzle is arranged in the center of the spraying head. According to the desulfurization and denitrification atomization spraying gun, the rectangular atomization nozzle design is adopted, atomization of the spraying gun is more evenly distributed accordingly, and it can be guaranteed that waste caused when ozone is sprayed to the inner wall of a flue can be avoided while the maximum nozzle radiating area is guaranteed. In addition, the drying and cooling gas is jet into the spraying gun body so that the temperature of the sprayed ozone can be guaranteed, then the reaction efficiency of the ozone, nitric oxide and sulfur oxide can be improved, and therefore the flue gas desulfurization and denitrification rate is increased. In addition, the spraying gun is convenient to assemble, disassemble and overhaul, and the service life of the spraying gun is prolonged.
