說明
explain
干法脫硫多用于硫化氫處理負荷小,或者對脫硫效果要求很高的工況。這時,干法脫硫多用于濕法脫硫或者生物脫硫之后,進一步脫硫。
Dry desulfurization is mostly used in the condition of low hydrogen sulfide treatment load or high desulfurization effect. At this time, dry desulfurization is mostly used for further desulfurization after wet desulfurization or biological desulfurization.
在制定脫硫效果時,建議根據(jù)后續(xù)設(shè)備(鍋爐或發(fā)電機)對硫化氫濃度的限制,以及沼氣與天然氣消耗量的比例,制定一個合理的脫除效果。我們通常建議終的硫化氫含量控制在25~100ppm。
When formulating the desulfurization effect, it is suggested to formulate a reasonable removal effect based on the limit of hydrogen sulfide concentration of subsequent equipment (boiler or generator) and the proportion of biogas and natural gas consumption. We usually recommend that the final hydrogen sulfide content be controlled at 25~100ppm.
