说明

explain

干法脱硫多用于硫化氢处理负荷小，或者对脱硫效果要求很高的工况。这时，干法脱硫多用于湿法脱硫或者生物脱硫之后，进一步脱硫。

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.

在制定脱硫效果时，建议根据后续设备(锅炉或发电机)对硫化氢浓度的限制，以及沼气与天然气消耗量的比例，制定一个合理的脱除效果。我们通常建议最终的硫化氢含量控制在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.
