沼气脱硫知识工作原理
Working Principle of Biogas Desulfurization Knowledge
沼气是有机物经厌氧消化而产生的可燃性气体。其特性与天然气相似,是一种很好的清洁燃料,是一种可再生能源。但是沼气中含有的硫化氢(H2S)成分,具有强腐蚀性,在利用过程中会损坏下游设备,并且在燃烧时排放出硫氧化物,对环境造成污染,因此大大限制了我们对沼气的利用。能提供全套的BIOREM 生物滴滤系统,处理不同硫化氢含量的沼气。我们的系统安全高效,并能实现有用副产物(硫磺)的回收,确保客户利益最大化。
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.
以往沼气脱硫是采用化学法或催化法,但是这些方法在运行过程中需要大量的化学药剂和较高的能耗,且会产生新的含硫化合物,如果得不到很好的处置会造成二次环境污染。与运行成本高昂的化学法或催化法对比,生物脱硫技术更为经济和有效。
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.
沼气提纯
为什么要对沼气脱硫?
Why do we need to desulfurize biogas?
在厌氧消化处理过程中,含硫化合物会被转为H2S,一般而言,沼气中H2S含量在0.1~0.2%之间。H2S具有很强的腐蚀性,不仅会造成管道、阀门、流量计的腐蚀,对内燃机的损坏格外的大。H2S燃烧后形成硫酸,降低了引擎机油的PH值,导致设备腐蚀,也会增加引擎机油的更换频率,缩短设备的使用寿命,增加设备维修、更换和维护成本。同时,H2S燃烧后还会对大气环境造成污染。脱硫系统使用安全的生物方法去除沼气中的H2S,不但保证您设备更长时间、更有效率的运行,更重要的是提高了效率为您节省时间和金钱。
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.
系统工作原理
Working Principle of the System
沼气脱硫系统是一套好氧生物滴滤系统,采用压力送风和上流式结构。沼气从系统底部进入滴滤塔,自下而上通过滤料。特殊研制的滤料在为嗜酸细菌生物膜的生长提供理想环境的同时,为气体自由通过提供了足够的空间。滤料和生物膜由循环水系统保持其湿度。当沼气进入系统并与生物膜接触后,硫化氢先溶解而后进一步被微生物氧化分解。形成的单质硫和硫酸盐化合物作为系统副产物由循环水出水排出。
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.
少量气体注入系统中,以维持气体的氧含量以达到最佳生物活性的需求。系统设计将对处理气体中的氧含量进行控制,多种联合安全联锁装置,以确保氧含量始终处于最低爆炸极限以下。
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.
