Small-section SNCR (selective non-catalytic reduction) spray gun arrangement structure of sludge incinerator

The utility model discloses a small-section SNCR (selective non-catalytic reduction) spray gun arrangement structure of a sludge incinerator, relates to the technical field of environmental protection, and mainly aims to uniformly spray a reducing agent and prevent the reducing agent from being sprayed onto a wall plate of a small-section shell to cause loss of the reducing agent and abrasion of the wall plate. According to the main technical scheme, the flue comprises a flue shell; the plurality of spray guns are uniformly arranged at the small cross section in the flue shell, and the difference between the spray angles of the plurality of spray guns and the arrangement angle of the small cross section in the flue shell is 30-45 degrees. 本实用新型公开了一种污泥焚烧炉小截面SNCR喷枪布置结构，涉及环境保护技术领域，主要目的在于均匀喷射出还原剂以及避免将还原剂喷射到小截面壳体的壁板上，造成还原剂的损失以及壁板的磨损。主要采用的技术方案为:烟道壳体；多个喷枪，其均匀的布置在烟道壳体内小截面处，所述多个喷枪的喷射角度与烟道壳体内小截面的布置角度相差30°到45°。
