Ammonia and air mixer for denitrification device
2012
The invention discloses an ammonia and air mixer for a denitrification device, comprising an ammonia injection pipeline (3), an ammonia injection nozzle (4), a turbulent flow bluff body (5), a cylinder body (6), a retracting pipe (7), a mixing pipe (8) and a diffuser pipe (9), wherein the cylinder body (6) is sequentially connected with the retracting pipe (7), the mixing pipe (8) and the diffuser pipe (9); the cylinder body (6) is internally provided with the ammonia injection pipeline (3); the ammonia injection nozzle (4) is arranged at the tail end of the ammonia injection pipeline (3); and the turbulent flow bluff body (5) is arranged in front of the ammonia injection nozzle (4). The ammonia and air mixer can uniformly distribute air, prevents gas collection, effectively prevents a water hammer phenomenon and prevents a membrane shell from being burst, and has the advantage of good washing effect.
