噴淋塔式水霧凈化,是一種主要凈化柴油燃燒產(chǎn)生的尾氣;設(shè)備整體采用不銹鋼材質(zhì)制作,利用堿液循環(huán)水噴淋中和凈化尾氣中NOx、SO2等酸性氣態(tài)污染物。發(fā)電機(jī)組尾氣處理工程特點(diǎn):它具有煙氣流速低、空氣阻力小,煙氣能與堿液充分接觸,占地面積小,耐腐蝕材料,結(jié)構(gòu)緊湊,使用壽命長,凈效率高等特點(diǎn)。水噴淋凈化:是一種溶液吸收的方法,它的特點(diǎn)是對含塵濃度的適應(yīng)性*,不僅可除去較粗的塵粒同時也能除去非常細(xì)小的粉塵,此外還可通過循環(huán)液除去可溶性有害氣體。水噴淋凈化對碳煙微粒、SO2的去除需解決碳煙微粒的憎水性和SO2的腐蝕性。
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.
對碳煙微粒的憎水性主要通過往清洗溶渡中加入滌煙劑來改良。滌煙劑是一種絮凝劑,具有高分散性、大的比表面、物理吸附性、電性及水化性強(qiáng)。對SO2的腐蝕性主要通過往清洗溶渡中加入堿性yao劑且采用耐腐蝕不銹鋼作為凈化器主要材料。在PH 值為11-12時,除SO2可達(dá)80-90%,同時通過水膜作用除去部分碳黑,從而達(dá)到清洗廢氣的目的。
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.
