除大量甲烷和二氧化碳外,從糞便中產(chǎn)生的沼氣還包含其他成分,例如硫化氫,雜質(zhì),水分,氮氧化物和硅氧烷。糞便厭氧發(fā)酵產(chǎn)生的沼氣包含大量的硫化氫,會腐蝕后端的設(shè)備,因此要將其脫硫,進行沼氣發(fā)電機組預(yù)處理。
In addition to large amounts of methane and carbon dioxide, biogas produced from faeces contains other components such as hydrogen sulfide, impurities, moisture, nitrogen oxides and siloxanes. Biogas produced by anaerobic fermentation of faeces contains a large amount of hydrogen sulfide, which will corrode the back-end equipment. Therefore, it is necessary to desulfurize and pretreat the biogas generator set.
未經(jīng)處理的沼氣不符合發(fā)動機氣體質(zhì)量的要求。沼氣直接進入燃氣發(fā)動機,這可能引起功率波動,設(shè)備爆震,停機甚至爆炸。如果僅對氣體進行處理,則水分,粉塵含量,壓力,溫度等均不能滿足設(shè)備要求。
The untreated biogas does not meet the requirements of engine gas quality. Biogas directly enters the gas engine, which may cause power fluctuation, equipment knock, shutdown or even explosion. If only the gas is treated, the moisture, dust content, pressure and temperature can not meet the equipment requirements.
由于管道中冷凝水的積聚,發(fā)電機組的可用性和發(fā)電量大大減少了;灰塵含量過多會導(dǎo)致壓力損失過大,并嚴重損壞設(shè)備的內(nèi)部氣缸;壓力和溫度不符合要求根據(jù)設(shè)備要求,設(shè)備經(jīng)常跳閘,可用率顯著下降,并且維護和維修成本增加。經(jīng)過改進的氣體預(yù)處理后,該裝置的發(fā)電量可提高70%。
Due to the accumulation of condensate water in the pipeline, the availability and power generation of the generator set are greatly reduced; excessive dust content will lead to excessive pressure loss and serious damage to the internal cylinder of the equipment; the pressure and temperature do not meet the requirements. According to the requirements of the equipment, the equipment often trips, the availability rate decreases significantly, and the maintenance and repair costs increase. After the improved gas pretreatment, the power generation of the device can be increased by 70%.
因此,氣體質(zhì)量處理的效果直接影響沼氣發(fā)電機組的效率,從而影響利潤。因此,選擇優(yōu)良的氣體除濕,除雜,電壓穩(wěn)定和恒溫發(fā)電機組預(yù)處理設(shè)備是確保沼氣發(fā)電機組良好運行的重要組成部分。
Therefore, the effect of gas quality treatment directly affects the efficiency of biogas generating units, thus affecting profits. Therefore, the selection of excellent gas dehumidification, impurity removal, voltage stability and constant temperature generator pretreatment equipment is an important part to ensure the good operation of biogas generator.
