用于沼氣中硫化氫的置換，脫硫效率可以達(dá)到99%，是生物氣體生產(chǎn)過程中起到優(yōu)化純化生物氣體，提高熱直效率。如氣體純度要求更高可使用雙塔。鋼制或玻璃。
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.
沼氣脫硫是基于沼氣中的硫化氫對環(huán)境、設(shè)備、管道以及儀表等產(chǎn)生污染和腐蝕的影響，故無論是直接用于燃燒或沼氣發(fā)電，都必須對沼氣進(jìn)行必要的脫硫、脫碳、脫水、除塵等處理。
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.
根據(jù)投料的成分不同，產(chǎn)生的沼氣中H2S含量略有差異，一般濃度為1~12g/m3，蛋白質(zhì)或硫鹽含量高的原料，發(fā)本地時沼氣中H2S的含量就較高。根據(jù)城市燃?xì)鈽?biāo)準(zhǔn)，液化石油氣中H2S含量不得超過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.
對厭氧消化產(chǎn)生的沼氣進(jìn)行脫硫，一般采用直接脫硫方法，按原理可分為干法、濕法和生物脫硫法。生物脫硫法是近年來出現(xiàn)的代替化學(xué)脫硫法的新型脫硫方式，在很多方面可以克服化學(xué)脫硫的不足。
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.
產(chǎn)品特點(diǎn)：
Product features:
1、 技術(shù)成熟，運(yùn)行可靠性高。
1. The technology is mature and the operation reliability is high.
