The utility model discloses an SNCR (selective non-catalytic reduction) ammonia injection fine regulation deep denitration system, which belongs to the technical field of flue gas treatment and comprises a reducing agent storage and supply unit, a demineralized water unit, a metering mixing unit, a fine distribution unit and an atomizing injection unit. The metering mixing unit is used for mixing and diluting ammonia water of the reducing agent storage and supply unit and demineralized water of the demineralized water unit into dilute ammonia water, and the dilute ammonia water enters the atomizing and spraying unit through the fine distribution unit and is sprayed into flue gas after being subjected to ultra-high fine atomization. According to the system, the flow of each spray gun can be accurately adjusted, and the ammonia water solution can be uniformly distributed to the corresponding spray guns, so that the aim of fully and uniformly mixing the ammonia water solution with flue gas is fulfilled.
