沼氣濕法脫硫設備的目的是為了將可能對后續(xù)設備及工藝產(chǎn)生不利影響的雜質(zhì)去除掉，主要的就是水蒸氣和硫化氫氣體。沼氣從發(fā)酵設備生成后，隨著在管道中的傳輸，溫度會逐漸下降，這一過程中，水蒸氣會發(fā)生凝結，變成冷凝水，如果是在冬天外界氣溫較低時，冷凝水可能會凍結堵塞管道。

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.

沼氣濕法脫硫設備的使用需要滿足以下要求:

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

1.配套完善的沼氣預處理系統(tǒng)

1. A well-equipped biogas pretreatment system

需要設置沼氣除濕、脫硫提純等一系列預處理，確保進入脫硫系統(tǒng)的沼氣質(zhì)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.脫硫液的規(guī)范配置和添加

2. Standardized configuration and addition of desulfurization solution

脫硫液需要定期補充，濃度和pH值需要嚴格控制，才能發(fā)揮理想的脫硫效果。

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.控制系統(tǒng)的精準調(diào)節(jié)

3. Precise adjustment of control system

要精確調(diào)控沼氣流量、壓力、溫度等參數(shù)，保證與脫硫液的完全接觸。

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

4.脫硫塔內(nèi)部的有效進行

4. Effective operation inside the desulfurization tower

需要有效進行塔內(nèi)混合，避免出現(xiàn)死角或沼氣短路問題。

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

5.完善的導出系統(tǒng)收集處理

5. A comprehensive export system for collection and processing

收集完全脫硫的沼氣，并處理脫硫后的酸性廢水。

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

6.防腐蝕的材質(zhì)選擇和維護

6. Material selection and maintenance for corrosion prevention

設備需要選擇耐腐蝕材料，并做好日常防腐維護。

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

7.運行參數(shù)的持續(xù)監(jiān)測和記錄

7. Continuous monitoring and recording of operating parameters

對過程參數(shù)實時監(jiān)測，找到理想脫硫穩(wěn)定狀態(tài)。

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

滿足上述要求，才能保證沼氣濕法脫硫系統(tǒng)的高效穩(wěn)定運行。

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