Energy-saving waste gas treatment device

The invention discloses an energy-saving waste gas treatment device. The device comprises a furnace end, a furnace hearth, a turbulent flow ring, a combustor and a tail gas inlet. The combustor is located at the front end of the furnace end and provided with a primary air inlet. By forming the tail gas inlet in the side wall of the front end of the furnace end, forming secondary air inlets in thetwo sides of the combustor, paving heat accumulating parts on the inner wall of a burning furnace and arranging airflow disturbance distribution walls and an airflow disturbance retainer ring, the burning furnace is divided into a plurality of spaces. Through the above multiple improvements, the two-airflow mixing degree is increased, and the fuel gas consumption is reduced; and meanwhile, the processing capacity of the whole burning furnace is improved. 本发明公开了一种节能废气处理装置，包括炉头、炉膛、湍流环、燃烧器和尾气入口，燃烧器位于炉头的前端，设有一次风入口。通过将尾气入口设于所述炉头的前端侧壁，二次风入口设于燃烧器的两侧，灼烧炉内壁铺设蓄热件，并通过设置气流扰动分布墙及气流扰动挡圈将灼烧炉分为多个空间。通过上述多个改进，提高了两气流混合度，降低燃料气消耗；同时提高整个灼烧
