沼氣進入塔體(ti) 的底部，並從(cong) 底部到頂部穿過填料層。通過變頻控製準確添加空氣。尾氣成分分析儀(yi) 監測沼氣出口的氧氣濃度，並與(yu) 鼓風機一起工作。
The biogas enters the bottom of the tower and passes through the filling layer from bottom to top. Accurately add air through variable frequency control. The exhaust gas composition analyzer monitors the oxygen concentration at the biogas outlet and works together with the blower.
空氣供應量大小由進入沼氣氣體(ti) 流量信號精確控製， 使得氧氣占到混合氣體(ti) 的百分比控製在一定範圍，可保證不會(hui) 因設計或供貨缺陷造成安全事故。同時空氣係統的安全設定向罐體(ti) 內(nei) 通入空氣，如果空氣量不足，脫硫效果會(hui) 快速降低。根據脫硫係統的負荷，通過一個(ge) 變頻器調節風機的轉速。在脫硫係統的後麵安裝氧氣傳(chuan) 感器作為(wei) 控製空氣通入量的安全保障。在正常運行過程中，出氣中氧氣剩餘(yu) 含量為(wei) 1.5~2.0%。如果沼氣中氧氣含量超過 1.75%，風機轉速將會(hui) 降低，如果達到 2.5%，風機將會(hui) 停止。此值可設定。
The size of the air supply is precisely controlled by the flow signal of the entering biogas gas, so that the percentage of oxygen in the mixed gas is controlled within a certain range, ensuring that safety accidents will not be caused by design or supply defects. At the same time, the safety setting of the air system introduces air into the tank body. If the air volume is insufficient, the desulfurization effect will quickly decrease. According to the load of the desulfurization system, the speed of the fan is adjusted through a frequency converter. Install an oxygen sensor at the back of the desulfurization system as a safety guarantee for controlling air intake. During normal operation, the remaining oxygen content in the outlet gas is 1.5-2.0%. If the oxygen content in biogas exceeds 1.75%, the fan speed will decrease. If it reaches 2.5%, the fan will stop. This value can be set.
循環泵設置備用泵，一個(ge) 故障時可快速切換到另一個(ge) 使用。
The circulating pump is equipped with a backup pump, which can quickly switch to another for use in case of a malfunction.
防爆係統的安全設置和生物脫硫的內(nei) 部設計都是防爆設計。另外，在生物脫硫設備間內(nei) 部裝有防爆氣體(ti) 監測器，如果甲烷水平超過低爆炸極限的 25%(LEL)，氣體(ti) 監測器將自動切斷電源，打開防爆風扇，防止爆炸風險。
The safety settings of the explosion-proof system and the internal design of biological desulfurization are both explosion-proof designs. In addition, an explosion-proof gas monitor is installed inside the biological desulfurization equipment room. If the methane level exceeds 25% of the minimum explosion limit (LEL), the gas monitor will automatically cut off the power supply and turn on the explosion-proof fan to prevent explosion risk.
為(wei) 了確保細菌的良好活性，使用熱交換器和溫度監測器來調節和控製係統溫度。 PH計用於(yu) 控製營養(yang) 液的添加。例如，如果PH值低於(yu) 設定值，則將新鮮的營養(yang) 液和稀釋水自動添加到脫硫塔中。同時，廢液自動排出，液位達到平衡。
To ensure the good activity of bacteria, heat exchangers and temperature monitors are used to regulate and control the system temperature. The pH meter is used to control the addition of nutrient solution. For example, if the pH value is lower than the set value, fresh nutrient solution and dilution water will be automatically added to the desulfurization tower. At the same time, the waste liquid is automatically discharged and the liquid level reaches equilibrium.
通過計量泵(計量泵設計為(wei) 一用一備)定期添加營養(yang) 液。液位開關(guan) 控製整體(ti) 液位平衡。
Regularly add nutrient solution through a metering pump (designed as one in use and one backup). The liquid level switch controls the overall liquid level balance.
