The invention discloses a glass kiln denitration system. The glass kiln denitration system comprises a first box body and a second box body. The first box body, an air inlet pipe, a frame body, a belt, a first motor, an annular pipe, a support column, a second liquid inlet valve, an ammonia gas sensor, a water pump, a water tank, a second motor, a rubber hose, a rotating shaft, an exhaust valve, adriving gear, an atomizing nozzle, the second box body, a third filter screen, a drawer, a communicating pipe, a driven gear, a water pump, a belt pulley, a second spiral blade rod, a first spiral blade rod, a snake-shaped heat exchange pipe, a partition plate, a first filter screen, a controller, a shell, active carbon balls, and a second filter screen cooperate with each other to solve the problems that in the denitration process of an existing glass kiln denitration system, ammonia water and flue gas are generally not evenly combined, the denitration efficiency is low, in addition, the flue gas heat exchange structure is generally single, the flue gas heat exchange effect is poor, and the system is inconvenient to use.
