Sleeve lime kiln device capable of reducing nitrogen oxide emission

The utility model relates to a sleeve lime kiln device capable of reducing nitrogen oxide emission. A sleeve lime kiln device capable of reducing nitrogen oxide emission comprises a sleeve kiln body, a first induced draft fan, a second induced draft fan, a driving fan, a chimney and a combustion-supporting air ring pipe. The sleeve kiln body comprises an upper burner and a lower burner; the chimney is provided with a flue gas air pipe, and the flue gas air pipe is divided into two paths: the first path of flue gas reaches an inlet of a driving fan through a first induced draft fan, is mixed with combustion-supporting air introduced by a Roots blower, and then is fed into a combustion chamber of the sleeve kiln body for combustion; and the second path of flue gas enters a combustion-supporting air ring pipe through a second induced draft fan, is mixed with combustion-supporting air and then respectively enters an upper burner and a lower burner for combustion. The utility model provides a sleeve lime kiln devi
