沼气湿法脱硫设备的目的是为了将可能对后续设备及工艺产生不利影响的杂质去除掉，主要的就是水蒸气和硫化氢气体。沼气从发酵设备生成后，随着在管道中的传输，温度会逐渐下降，这一过程中，水蒸气会发生凝结，变成冷凝水，如果是在冬天外界气温较低时，冷凝水可能会冻结堵塞管道。

The purpose of biogas wet desulfurization equipment is to remove impurities that may have adverse effects on subsequent equipment and processes, mainly water vapor and hydrogen sulfide gas. After biogas is generated from fermentation equipment, its temperature gradually decreases as it is transported through pipelines. During this process, water vapor condenses and becomes condensed water. If the external temperature is low in winter, the condensed water may freeze and block the pipeline.

沼气湿法脱硫设备的使用需要满足以下要求:

The use of biogas wet desulfurization equipment needs to meet the following requirements:

1.配套完善的沼气预处理系统

1. A well-equipped biogas pretreatment system

需要设置沼气、脱硫提纯等一系列预处理，确保进入脱硫系统的沼气质量合格。

A series of pretreatment processes such as biogas dehumidification, desulfurization and purification need to be set up to ensure the quality of biogas entering the desulfurization system is qualified.

2.脱硫液的规范配置和添加

2. Standardized configuration and addition of desulfurization solution

脱硫液需要定期补充，浓度和pH值需要严格控制，才能发挥理想的脱硫效果。

The desulfurization solution needs to be regularly replenished, and the concentration and pH value need to be strictly controlled in order to achieve the desired desulfurization effect.

3.控制系统的精准调节

3. Precise adjustment of control system

要精确调控沼气流量、压力、温度等参数，保证与脱硫液的完全接触。

Accurate control of biogas flow rate, pressure, temperature and other parameters is necessary to ensure complete contact with the desulfurization solution.

4.脱硫塔内部的有效进行

4. Effective operation inside the desulfurization tower

需要有效进行塔内混合，避免出现死角或沼气短路问题。

Effective mixing inside the tower is necessary to avoid dead corners or biogas short circuits.

5.完善的导出系统收集处理

5. A comprehensive export system for collection and processing

收集完全脱硫的沼气，并处理脱硫后的酸性废水。

Collect fully desulfurized biogas and treat the acidic wastewater after desulfurization.

6.防腐蚀的材质选择和维护

6. Material selection and maintenance for corrosion prevention

设备需要选择耐腐蚀材料，并做好日常防腐维护。

The equipment needs to be made of corrosion-resistant materials and undergo daily anti-corrosion maintenance.

7.运行参数的持续监测和记录

7. Continuous monitoring and recording of operating parameters

对过程参数实时监测，找到理想脱硫稳定状态。

Real time monitoring of process parameters to find the ideal desulfurization stable state.

满足上述要求，才能保证沼气湿法脱硫系统的稳定运行。

Only by meeting the above requirements can the efficient and stable operation of the biogas wet desulfurization system be ensured.
