Summary:The invention discloses a bypass exhaust purification system and method for a cement kiln, and belongs to the technical field of cement production equipment. The system is characterized by comprisinga cement kiln smoke chamber, a smoke outlet of the cement kiln smoke chamber is communicated with a shock cooling chamber device, and a gas outlet of the shock cooling chamber device is sequentially communicated with a dust collector, a fan, a waste gas treatment system and a chimney in series. An ammonia spraying device is arranged in the shock cooling chamber of the shock cooling chamber device,and a lime spraying device is installed at an outlet of the shock cooling chamber device. Smoke discharged from the bypass is subjected to dust collection and purification to reach the particle emission standard, the purified smoke is discharged into the atmosphere, and the collected fine powder contains more harmful components and is independently stored or used for other purposes, so that the cement firing system is str
