Low-nitrogen incomplete regeneration flue gas incineration system

The invention discloses a low-nitrogen incomplete regeneration flue gas incineration system and aims to solve the problem of low generation of NOx in the incineration process of incomplete regeneration flue gas in an incinerator. Therefore, the low-nitrogen incomplete regeneration flue gas incineration system comprises an incinerator, a regeneration flue gas cyclone and an isolation barrel, an air outlet of the regeneration flue gas cyclone is in butt joint with a flue gas inlet of the incinerator, the regeneration flue gas cyclone is arranged around the isolation barrel, a combustor is arranged at the tail end of the isolation barrel, and the tail end of the isolation barrel is provided with an air inlet. And a secondary combustion-supporting air inlet pipe is arranged between the regenerated flue gas cyclone and the isolation cylinder. 本发明公开了一种低氮不完全再生烟气焚烧系统，旨在解决不完全再生烟气在焚烧炉的焚烧过程中NOx的低生成问题。为此，本发明实施例提供的低氮不完全再生烟气焚烧系统，包括焚烧炉、再生烟气旋流器和隔离筒，所述再生烟气旋流器的出风口与所述焚烧炉的进烟口对接，所述再生烟气旋流器环绕所述隔离筒设置，所述隔离筒的尾端设有燃烧器，所述再生烟气旋流器与所述隔离筒之间设
