消化池厭氧進程產(chǎn)生的沼氣是一種混合氣體,主要成分CH4、CO2以及水汽,它是一種很易燃的燃?xì)?,但也會污染環(huán)境,甚至有著嚴(yán)重的安全隱患。因而,需要對進行沼氣預(yù)處理工作,以便其更好地運用,并避免危害的發(fā)生。
Biogas produced by anaerobic process of digester is a kind of mixed gas, which is mainly composed of CH4, CO2 and water vapor. It is a very flammable gas, but it also pollutes the environment, and even has serious security risks. Therefore, it is necessary to pretreat biogas in order to make better use of it and avoid harm.
沼氣發(fā)電是一項廣泛運用的沼氣運用項目。但沼氣含有雜質(zhì)且沼氣的流量、壓力、溫度、濃度等都很不穩(wěn)定,直接用于燃?xì)獍l(fā)電必定形成燃?xì)獍l(fā)電機的設(shè)備腐蝕、磨損等問題,然后嚴(yán)重縮短燃?xì)獍l(fā)電機的壽數(shù)。所以在運用之前,須對沼氣進行預(yù)處理。
Biogas power generation is a widely used biogas application project. However, biogas contains impurities and its flow, pressure, temperature and concentration are very unstable. If biogas is directly used in gas-fired power generation, it will cause corrosion, wear and other problems of gas-fired generator equipment, and then seriously shorten the life of gas-fired generator. Therefore, biogas must be pretreated before application.
為滿足沼氣發(fā)電機對沼氣的質(zhì)量要求,需增設(shè)沼氣過濾枯燥加壓體系,對沼氣進行凈化加壓后送入沼氣發(fā)電機發(fā)電。對沼氣進行更有效地沼氣預(yù)處理工作,提升沼氣的質(zhì)量,添加沼氣發(fā)電的運用率,削減對發(fā)電機的損害,以便獲得更高的經(jīng)濟和環(huán)保效益。
In order to meet the quality requirements of biogas generator for biogas, it is necessary to add biogas filtration pressure system to purify and pressurize biogas and send it to biogas generator for power generation. In order to obtain higher economic and environmental benefits, biogas pretreatment should be carried out more effectively to improve the quality of biogas, increase the utilization rate of biogas power generation, and reduce the damage to the generator.
