沼氣脫硫知識工作原理

沼氣脫硫知識工作原理
Working Principle of Biogas Desulfurization Knowledge
沼氣是有機物經厭氧消化而產生的可燃性氣體。其特性與天然氣相似,是一種很好的清潔燃料,是一種可再生能源。但是沼氣中含有的硫化氫(H2S)成分,具有強腐蝕性,在利用過程中會損壞下游設備,并且在燃燒時排放出硫氧化物,對環境造成污染,因此大大限制了我們對沼氣的利用。能提供全套的BIOREM 生物滴濾系統,處理不同硫化氫含量的沼氣。我們的系統安全高效,并能實現有用副產物(硫磺)的回收,確保客戶利益大化。
Biogas is a flammable gas produced by anaerobic digestion of organic matter. Its characteristics are similar to natural gas. It is a good clean fuel and a renewable energy source. However, the hydrogen sulfide (H2S) contained in biogas is highly corrosive, which can damage downstream equipment in the process of utilization, and emit sulfur oxides when burning, which pollutes the environment, thus greatly restricting our use of biogas. It can provide a complete BIOREM biotrickling filter system to treat biogas with different hydrogen sulfide content. Our system is safe and efficient, and can achieve the recovery of useful by-products (sulfur) to ensure maximum customer benefits.
以往沼氣脫硫是采用化學法或催化法,但是這些方法在運行過程中需要大量的化學藥劑和較高的能耗,且會產生新的含硫化合物,如果得不到很好的處置會造成二次環境污染。與運行成本高昂的化學法或催化法對比,生物脫硫技術更為經濟和有效。
In the past, biogas desulfurization used chemical or catalytic methods, but these methods need a lot of chemical agents and high energy consumption in the operation process, and will produce new sulfur compounds, if not well disposed of, it will cause secondary environmental pollution. Biological desulfurization technology is more economical and effective than chemical or catalytic methods, which are expensive to operate.
沼氣提純
為什么要對沼氣脫硫?
Why do we need to desulfurize biogas?
在厭氧消化處理過程中,含硫化合物會被轉為H2S,一般而言,沼氣中H2S含量在0.1~0.2%之間。H2S具有很強的腐蝕性,不僅會造成管道、閥門、流量計的腐蝕,對內燃機的損壞格外的大。H2S燃燒后形成硫酸,降低了引擎機油的PH值,導致設備腐蝕,也會增加引擎機油的更換頻率,縮短設備的使用壽命,增加設備維修、更換和維護成本。同時,H2S燃燒后還會對大氣環境造成污染。脫硫系統使用安全的生物方法去除沼氣中的H2S,不但保證您設備更長時間、更有效率的運行,更重要的是提高了效率為您節省時間和金錢。
During anaerobic digestion, sulfur compounds are converted to H2S. Generally speaking, the content of H2S in biogas is between 0.1% and 0.2%. H2S is highly corrosive, which not only causes corrosion of pipelines, valves and flowmeters, but also causes great damage to internal combustion engines. H2S forms sulfuric acid after combustion, which reduces the PH value of engine oil and causes equipment corrosion. It also increases the replacement frequency of engine oil, shortens the service life of equipment, and increases the cost of equipment maintenance, replacement and maintenance. At the same time, the combustion of H2S will also pollute the atmospheric environment. The desulfurization system uses safe biological methods to remove H2S from biogas, which not only guarantees the longer and more efficient operation of your equipment, but also improves the efficiency and saves you time and money.
系統工作原理
Working Principle of the System
沼氣脫硫系統是一套好氧生物滴濾系統,采用壓力送風和上流式結構。沼氣從系統底部進入滴濾塔,自下而上通過濾料。特殊研制的濾料在為嗜酸細菌生物膜的生長提供理想環境的同時,為氣體自由通過提供了足夠的空間。濾料和生物膜由循環水系統保持其濕度。當沼氣進入系統并與生物膜接觸后,硫化氫先溶解而后進一步被微生物氧化分解。形成的單質硫和硫酸鹽化合物作為系統副產物由循環水出水排出。
Biogas desulfurization system is an aerobic biological trickling filtration system, which adopts pressure air supply and upflow structure. Biogas enters the trickling filter from the bottom of the system and passes through the filter material from bottom to top. The specially developed filter material not only provides an ideal environment for the growth of acidophilic bacterial biofilm, but also provides enough space for the free passage of gas. The filter media and biofilm are maintained by the circulating water system. When biogas enters the system and contacts with biofilm, hydrogen sulfide dissolves first and then is oxidized and decomposed by microorganisms. The sulfur and sulfate compounds formed are discharged from the circulating water as by-products of the system.
少量氣體注入系統中,以維持氣體的氧含量以達到佳生物活性的需求。系統設計將對處理氣體中的氧含量進行控制,多種聯合安全聯鎖裝置,以確保氧含量始終處于低爆炸極限以下。
A small amount of gas is injected into the system to maintain the oxygen content of the gas in order to meet the requirement of optimum biological activity. The design of the system will control the oxygen content in the treated gas, and a variety of joint safety interlocking devices will be used to ensure that the oxygen content is always below the minimum explosion limit.
