垃圾填埋氣預(yù)處理產(chǎn)生于垃圾填埋過程中，是垃圾中可以降解的有機物在降解過程中的一種副產(chǎn)品，它的主要成分是甲烷和二氧化碳，它們都是無色無味的氣體；帶氣味的物質(zhì)來源是一些微量成份，一般來說，垃圾填埋氣中甲烷的含量在50-60%，二氧化碳為40-50%，微量成分占1%左右，這些氣體如果直接排放到大氣中，易燃易爆安全隱患很大，而且還會對環(huán)境成嚴(yán)重污染，溫室效應(yīng)嚴(yán)重，同時也是一種資源與能源的浪費。垃圾填埋氣回收有著普遍的應(yīng)用，例如發(fā)電或作為燃料能源，其中用作燃?xì)獍l(fā)電是比較普遍的利用方式。
Landfill gas pretreatment is produced in the process of landfill, which is a by-product of degradable organic matter in the process of degradation. Its main components are methane and carbon dioxide, which are colorless and odorless gases. The source of odorous substances is some trace components. Generally speaking, the content of methane in landfill gas is 50-60%, carbon dioxide is 40-50%, and the content of trace components is 40-50% If these gases are directly discharged into the atmosphere, there will be a lot of flammable and explosive safety hazards, and it will also cause serious pollution to the environment, the greenhouse effect is serious, and it is also a waste of resources and energy. Landfill gas recovery has a wide range of applications, such as power generation or as fuel energy, among which gas power generation is the most common way.
垃圾填埋發(fā)電廠是以垃圾填埋氣燃料產(chǎn)生動力來驅(qū)動燃?xì)獍l(fā)電機組產(chǎn)生電能。垃圾填埋氣經(jīng)垃圾填埋場氣體收集系管道收集至電站，從氣井母管收集的氣體含有大量的有害成分和水分，嚴(yán)重影響燃?xì)獍l(fā)電機組的運行，一般在垃圾填埋氣進行回收利用時，通常會進行預(yù)處理，確保提供符合燃?xì)獍l(fā)電機組發(fā)電要求的潔凈氣體；垃圾填埋氣預(yù)處理系統(tǒng)被安裝在燃?xì)獍l(fā)電機組進氣管路前端，它是垃圾填埋場填埋氣體發(fā)電工程非常重要的設(shè)備。
Landfill power plant uses landfill gas fuel to generate power to drive gas-fired generating units to generate electricity. The landfill gas is collected to the power station through the gas collection pipeline of the landfill, and the gas collected from the gas well header contains a lot of harmful components and moisture, which seriously affects the operation of the gas-fired power generation unit. Generally, when the landfill gas is recycled, it is usually pretreated to ensure that the clean gas meeting the power generation requirements of the gas-fired power generation unit is provided The system is installed in the front of the gas generator air inlet pipeline, which is a very important equipment for landfill gas power generation project.
垃圾填埋氣的預(yù)處理裝置通過氣體吸收裝置對填埋氣進行收集，送入雜質(zhì)分離器將雜質(zhì)去除，脫硫裝置去除垃圾填埋氣內(nèi)的硫化氫。再經(jīng)過初級過濾裝置去除粉塵或細(xì)小顆粒，經(jīng)過冷卻脫水裝置進行初步脫水，再以氣液分離器去除水汽，而后經(jīng)鼓風(fēng)機負(fù)壓抽出再經(jīng)精密過濾器進一步去除雜質(zhì)從而得到初步處理完畢的垃圾填埋氣，具有良好的填埋凈化預(yù)處理效果，有效去除了有毒有害雜質(zhì)。
The pretreatment device of landfill gas collects landfill gas through gas absorption device, sends it to impurity separator to remove impurities, and desulfurization device removes hydrogen sulfide in landfill gas. After that, the dust or fine particles are removed by the primary filtration device, the initial dehydration is carried out by the cooling dehydration device, the water vapor is removed by the gas-liquid separator, and then the negative pressure is extracted by the blower, and then the impurities are further removed by the precision filter, so as to obtain the landfill gas that has been preliminarily treated, which has a good landfill purification pretreatment effect and effectively removes the toxic and harmful impurities.
