Description

Technical Field

[0001] The utility model relates to the field of denitration, and particularly relates to a denitration ammonia injection grid flow disturbing and mixing device. Background Technique

[0002] The denitration ammonia injection grid flow disturbing and mixing device is a key component used in the flue gas denitration system, which is used to ensure the effective mixing of ammonia water and flue gas to achieve the denitration reaction. When the flue gas passes through the grid, the grid will cause the disturbance and mixing of the air flow, so that the sprayed ammonia water can be quickly mixed into the flue gas. This mixing process is achieved through the openings or porous structures on the grid, as well as the turbulence and vortex effects generated when the flue gas flows through.

[0003] The existing ammonia water spraying is generally arranged near the grid plate to spray the flue gas better to achieve denitration. The existing spraying pipe direction and method are fixed and cannot be slightly rotated to spray the flue gas, resulting in incomplete contact between the flue gas and ammonia water.
