沼气收集系统。沼气收集系统是将沼气从沼气池中收集出来的设备。它通常包括沼气收集罩、沼气管道和沼气收集井等。沼气收集罩覆盖在沼气池上方,通过管道将沼气引导到收集井中,再通过管道输送到提纯设备。
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.
沼气设备。沼气中含有大量的水蒸气,如果不去除水分,会影响沼气的燃烧效果。因此,沼气提纯过程中需要使用设备。常见的设备有冷凝器和吸附剂。冷凝器通过降低沼气温度,使水蒸气凝结成液体,然后通过排水管排出。吸附剂则通过吸附水分分子,将其从沼气中去除。
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.
沼气脱硫设备。沼气中含有硫化氢等有害气体,如果不去除,会对环境和设备造成损害。因此,沼气提纯过程中需要使用脱硫设备。常见的脱硫设备有湿法脱硫和干法脱硫。湿法脱硫是通过将沼气与碱性溶液接触,使硫化氢转化为硫化钠或硫化钙,然后通过沉淀或过滤将其去除。干法脱硫则是通过将沼气与吸附剂接触,使硫化氢被吸附,然后将吸附剂进行再生。
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.
沼气压缩设备。沼气提纯后,可以通过压缩设备将其压缩成高压沼气,以便更好地储存和运输。常见的压缩设备有压缩机和储气罐。压缩机通过增加沼气的压力,将其压缩成高压沼气。储气罐则用于储存压缩后的沼气,以便后续使用。
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.
除了上述设备,沼气提纯过程中还需要使用一些辅助设备,如泵、阀门、管道等,用于输送和控制沼气的流动。
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.
