选择性催化还原(SCR)脱硝工艺

选择性催化剂还原法( Selective Catalytic Reduction)简称SCR,指在一定的温度和催化剂的作用下,以液氨或尿素作为还原剂,有选择性地与烟气中的氮氧化物反应并生成无毒无污染的氮气和水。该技术可使用液氨或尿素为脱硝还原剂。

SCR脱硝工艺采用催化剂使氮氧化物发生还原反应,反应温度较低300~ 450°C 。其方法是将还原剂喷入装有催化剂的反应器内,烟气通过催化剂与之产生化学反应进行脱硝。此工艺的脱硝效率可达90%以上,是国内外电厂应用较多,技术成熟的一种烟气脱硝技术

SCR脱硝工艺主要用于布置在燃煤和燃油电厂的固态排渣或者液态排渣锅炉的烟气下游。在一定温度和有催化剂存在的情况下,向烟气中通入作为还原剂的NH3或者尿素等,将烟气中的NOx还原为无害的氮气( N2 )和水( H2O ),从而达到脱除NOx、净化烟气和减少电厂污染物排放的目的,其主要化学反应方程式如下:

4NO+4NH3+02→6H2O+4N2 NO+NO2+2NH3→3H20+2N26NO2+8NH3→7N2+12H20

以上反应过程中同时伴随以下副反应的发生: 2S02+O2→2S03


SCR特点

脱硝效率高,能达到90%以上;

出口氨气逃逸浓度低,达到国家标准;SO2转化为S03的转化率较低,一般小于1%;

蜂窝状或板式催化剂单元设计,保证催化剂的有效表面积;特殊气体均布装置保证烟气和还原剂均匀分布;达到很好的脱硝效率;反应器可以布置省煤器和空预器之间,或脱硫塔之后;

提供氨水或者液NH3两种可选方案,可满足不同需要;系统阻力小,低于1000Pa;

适应温度范围广:160 ~ 510°C;成熟稳定。


适用领域

SCR工艺主要用于燃煤发电锅炉、热电联产锅炉、集中供热锅炉、焚化炉、烧结机、球团窑炉、焦化炉、玻璃窑炉、陶瓷窑炉等窑炉的烟气脱硝
