Tail gas treatment principle of industrial generator set: tail gas treatment tower of generator set adopts

喷淋塔式水雾净化，是一种主要净化柴油燃烧产生的尾气；设备整体采用不锈钢材质制作，利用碱液循环水喷淋中和净化尾气中NOx、SO2等酸性气态污染物。发电机组尾气处理工程特点：它具有烟气流速低、空气阻力小，烟气能与碱液充分接触，占地面积小，耐腐蚀材料，结构紧凑，使用寿命长，净效率高等特点。水喷淋净化：是一种溶液吸收的方法，它的特点是对含尘浓度的适应性*，不仅可除去较粗的尘粒同时也能除去非常细小的粉尘，此外还可通过循环液除去可溶性有害气体。水喷淋净化对碳烟微粒、SO2的去除需解决碳烟微粒的憎水性和SO2的腐蚀性。

Spray tower water mist purification is mainly used to purify the tail gas produced by diesel combustion; The equipment is made of stainless steel as a whole, and the acid gaseous pollutants such as NOx and SO2 in the tail gas are neutralized and purified by spraying alkali liquor circulating water. Characteristics of tail gas treatment project of generator set: it has the characteristics of low flue gas flow rate, low air resistance, full contact between flue gas and alkali liquor, small floor area, corrosion-resistant materials, compact structure, long service life and high net efficiency. Water spray purification: it is a solution absorption method, which is characterized by its adaptability to dust concentration. It can remove not only coarse dust particles, but also very fine dust. In addition, it can also remove soluble harmful gases through circulating liquid. For the removal of soot particles and SO2 by water spray purification, the hydrophobicity of soot particles and the corrosivity of SO2 need to be solved.

对碳烟微粒的憎水性主要通过往清洗溶渡中加入涤烟剂来改良。涤烟剂是一种絮凝剂，具有高分散性、大的比表面、物理吸附性、电性及水化性强。对SO2的腐蚀性主要通过往清洗溶渡中加入碱性yao剂且采用耐腐蚀不锈钢作为净化器主要材料。在PH 值为11－12时，除SO2可达80－90％，同时通过水膜作用除去部分碳黑，从而达到清洗废气的目的。

The hydrophobicity of soot particles is mainly improved by adding smoke cleaning agent to the cleaning solution. Smoke cleaning agent is a flocculant with high dispersion, large specific surface, strong physical adsorption, electricity and hydration. The corrosivity of SO2 is mainly by adding alkaline Yao agent into the cleaning solution and using corrosion-resistant stainless steel as the main material of the purifier. When the pH value is 11-12, the removal of SO2 can reach 80-90%. At the same time, part of carbon black is removed through the action of water film, so as to achieve the purpose of cleaning waste gas.
