1. 脱硫剂宜采用氧化铁,脱硫剂空速宜为200h-1~400h-1;
1. The desulfurizer should be iron oxide, and the space velocity of desulfurizer should be 200 H-1 ~ 400 H-1;
2 .沼气初次通过脱硫剂每米床层时的压力降应小于100Pa;
2. The pressure drop of biogas passing through the desulfurizer bed for the first time should be less than 100Pa;
3 .每层颗粒状脱硫剂装填高度宜为1.0m~1.4m;
3. The filling height of each layer of granular desulfurizer should be 1.0m ~ 1.4m;
4 .沼气通过颗粒状脱硫剂的线速度宜为0.020m/s~0.025m/s;
4. The linear velocity of biogas passing through granular desulfurizer should be 0.020m/s ~ 0.025m/s;
5 .脱硫塔的操作温度应为25℃~35℃,冰冷地区的脱硫设施应有保温或采暖措施;
5. The operating temperature of desulfurization tower should be 25 ℃ ~ 35 ℃. Thermal insulation or heating measures should be taken for desulfurization facilities in cold areas;

6 .脱硫塔底部的低处应设置排污阀;
6. Blowdown valve should be set at the bottom of desulfurization tower;
7 .每台脱硫装置应有独立的放散管;
7. Each desulfurization unit shall have an independent vent pipe;
8 .脱硫剂在塔内再生时应设置进空气管,在线再生时,宜配备在线氧监控系统。
8. When the desulfurizer is regenerated in the tower, the air inlet pipe should be set. When the desulfurizer is regenerated online, the online oxygen monitoring system should be equipped.
