| 摘 要： | 介绍了双氧水脱硫的基本原理,阐述了维持H2O2一定浓度的必要性,分析了稀硫酸浓度对SO2脱除率、气相中硫酸雾含量的影响,提出了适宜的控制浓度。双氧水法脱硫的稀硫酸w(H2SO4)一般不宜超过30%,w(H2O2)控制在0.3%~0.5%,硫磺制酸企业稀硫酸w(H2SO4)可适当降低至20%~25%。

| Abstract: | The basic principle of hydrogen peroxide desulfurization is introduced,the necessity of maintaining a certain concentration of H2O2 is expounded,the influence of dilute sulphuric acid concentration on SO_(2 )removal rate and sulphuric acid mist content in gas phase is analyzed,and the appropriate control concentration is put forward.In general,the w(H2SO4)of dilute sulphuric acid should not exceed 30%,and the w(H2O2)should be controlled in the range of 0.3%-0.5%.The w(H2SO4)of dilute sulphuric acid in sulphur-burning sulphuric acid plants can be appropriately reduced to 20%-25%. |
