用于沼气中硫化氢的置换,脱硫效率可以达到99%,是生物气体生产过程中起到优化纯化生物气体,提高热直效率。如气体纯度要求更高可使用双塔。钢制或玻璃。
For the replacement of hydrogen sulfide in biogas, the desulfurization efficiency can reach 99%, which can optimize the purification of biological gas and improve the thermal efficiency during the production of biological gas. If the gas purity requirement is higher, double towers can be used. Steel or glass.
沼气脱硫是基于沼气中的硫化氢对环境、设备、管道以及仪表等产生污染和腐蚀的影响,故无论是直接用于燃烧或沼气发电,都必须对沼气进行必要的脱硫、脱碳、脱水、除尘等处理。
Biogas desulfurization is based on the impact of hydrogen sulfide in biogas on the environment, equipment, pipelines, instruments, etc., resulting in pollution and corrosion. Therefore, whether directly used for combustion or biogas power generation, biogas must be treated with necessary desulfurization, decarburization, dehydration, dust removal, etc.
根据投料的成分不同,产生的沼气中H2S含量略有差异,一般浓度为1~12g/m3,蛋白质或硫盐含量高的原料,发本地时沼气中H2S的含量就较高。根据城市燃气标准,液化石油气中H2S含量不得超过20mg/m3。
According to the composition of the feed, the H2S content in the biogas produced is slightly different, and the general concentration is 1~12g/m3. For raw materials with high protein or sulfur salt content, the H2S content in the biogas will be higher when it is delivered locally. According to the urban gas standard, the H2S content in LPG shall not exceed 20mg/m3.
对厌氧消化产生的沼气进行脱硫,一般采用直接脱硫方法,按原理可分为干法、湿法和生物脱硫法。生物脱硫法是近年来出现的代替化学脱硫法的新型脱硫方式,在很多方面可以克服化学脱硫的不足。
The direct desulfurization method is generally adopted for the desulfurization of biogas produced by anaerobic digestion, which can be divided into dry method, wet method and biological desulfurization according to the principle. Biological desulfurization is a new type of desulfurization method that has emerged in recent years to replace chemical desulfurization, and it can overcome the shortcomings of chemical desulfurization in many aspects.
