沼氣收集係統。沼氣收集係統是將沼氣從(cong) 沼氣池中收集出來的設備。它通常包括沼氣收集罩、沼氣管道和沼氣收集井等。沼氣收集罩覆蓋在沼氣池上方，通過管道將沼氣引導到收集井中，再通過管道輸送到提純設備。
Biogas collection system. The biogas collection system is a device that collects biogas from a biogas digester. It usually includes biogas collection covers, biogas pipelines, and biogas collection wells. The biogas collection hood is covered above the biogas tank, and the biogas is guided to the collection well through pipelines, which are then transported to the purification equipment.
沼氣除濕設備。沼氣中含有大量的水蒸氣，如果不去除水分，會(hui) 影響沼氣的燃燒效果。因此，沼氣提純過程中需要使用除濕設備。常見的除濕設備有冷凝器和吸附劑。冷凝器通過降低沼氣溫度，使水蒸氣凝結成液體(ti) ，然後通過排水管排出。吸附劑則通過吸附水分分子，將其從(cong) 沼氣中去除。
Biogas dehumidification equipment. Biogas contains a large amount of water vapor, and if the moisture is not removed, it will affect the combustion effect of biogas. Therefore, dehumidification equipment is required during the purification process of biogas. Common dehumidification equipment includes condensers and adsorbents. The condenser condenses the water vapor into a liquid by lowering the temperature of the biogas, which is then discharged through a drainage pipe. Adsorbents remove water molecules from biogas by adsorbing them.
沼氣脫硫設備。沼氣中含有硫化氫等有害氣體(ti) ，如果不去除，會(hui) 對環境和設備造成損害。因此，沼氣提純過程中需要使用脫硫設備。常見的脫硫設備有濕法脫硫和幹法脫硫。濕法脫硫是通過將沼氣與(yu) 堿性溶液接觸，使硫化氫轉化為(wei) 硫化鈉或硫化鈣，然後通過沉澱或過濾將其去除。幹法脫硫則是通過將沼氣與(yu) 吸附劑接觸，使硫化氫被吸附，然後將吸附劑進行再生。
Biogas desulfurization equipment. Biogas contains harmful gases such as hydrogen sulfide, which, if not removed, can cause damage to the environment and equipment. Therefore, desulfurization equipment is required during the purification process of biogas. Common desulfurization equipment includes wet desulfurization and dry desulfurization. Wet desulfurization is achieved by contacting biogas with an alkaline solution to convert hydrogen sulfide into sodium sulfide or calcium sulfide, and then removing it through precipitation or filtration. Dry desulfurization involves contacting biogas with an adsorbent to adsorb hydrogen sulfide, and then regenerating the adsorbent.
沼氣壓縮設備。沼氣提純後，可以通過壓縮設備將其壓縮成高壓沼氣，以便更好地儲(chu) 存和運輸。常見的壓縮設備有壓縮機和儲(chu) 氣罐。壓縮機通過增加沼氣的壓力，將其壓縮成高壓沼氣。儲(chu) 氣罐則用於(yu) 儲(chu) 存壓縮後的沼氣，以便後續使用。
Biogas compression equipment. After purifying biogas, it can be compressed into high-pressure biogas through compression equipment for better storage and transportation. Common compression equipment includes compressors and gas storage tanks. The compressor compresses biogas into high-pressure biogas by increasing its pressure. Gas storage tanks are used to store compressed biogas for subsequent use.
除了上述設備，沼氣提純過程中還需要使用一些輔助設備，如泵、閥門、管道等，用於(yu) 輸送和控製沼氣的流動。
In addition to the above equipment, some auxiliary equipment such as pumps, valves, pipelines, etc. are also required during the biogas purification process to transport and control the flow of biogas.
