為了讓含有硫化氫等腐蝕性的氣體適合發(fā)電機(jī)組、沼氣爐等設(shè)備使用，必須對(duì)沼氣進(jìn)行處理。我們一般采用經(jīng)濟(jì)實(shí)惠的干式脫硫法。主要設(shè)備有：脫硫塔、 緩沖罐、脫水器、正負(fù)壓、智能控制柜等部件組成。對(duì)去除硫化氫、水分等具有高效簡(jiǎn)單、管理方便、造價(jià)低、壽命長(zhǎng)、運(yùn)行可靠等優(yōu)點(diǎn)。適用于硫化氫含量低，處理氣量小，脫硫精度要求高的氣體。
In order to make corrosive gases such as hydrogen sulfide suitable for use in power generation units, biogas furnaces, and other equipment, biogas must be treated. We generally use an economical dry desulfurization method. The main equipment consists of components such as desulfurization tower, buffer tank, dehydrator, positive and negative pressure, intelligent control cabinet, etc. It has the advantages of high efficiency, simple management, low cost, long service life, and reliable operation for removing hydrogen sulfide, moisture, etc. Suitable for gases with low hydrogen sulfide content, low gas processing capacity, and high desulfurization accuracy requirements.
脫硫系統(tǒng)的設(shè)計(jì)：
Design of desulfurization system:
根據(jù)用戶的實(shí)際氣體數(shù)量和氣體中硫化氫的含量，專門量身設(shè)計(jì)脫硫各個(gè)系統(tǒng)的外形尺寸和內(nèi)部結(jié)構(gòu)。所以，對(duì)于不同類型的氣體、不同硫化氫含量、不同壓力的氣體，脫硫設(shè)備的外形尺寸與內(nèi)部結(jié)構(gòu)也有所不同。
According to the user's Real gas quantity and hydrogen sulfide content in the gas, the overall dimensions and internal structure of each desulfurization system are specially designed. So, for different types of gases, different hydrogen sulfide content, and different pressures, the external dimensions and internal structure of desulfurization equipment also vary.
為實(shí)時(shí)監(jiān)控再生過(guò)程中硫化物及硫化物與空氣中的氧氣反應(yīng)速度，可以增加溫度監(jiān)控設(shè)備，避免因再生過(guò)程中進(jìn)入的空氣量過(guò)大，放熱反應(yīng)劇烈，溫度超過(guò)脫硫劑的燃點(diǎn)而導(dǎo)致發(fā)生意外火災(zāi)等意外。
In order to monitor the reaction rate of sulfide and sulfide with oxygen in the air during the regeneration process in real time, temperature monitoring equipment can be added to avoid accidental fire caused by excessive amount of air entering during the regeneration process, severe Exothermic reaction, and temperature exceeding the ignition point of the desulfurizer.
沼氣脫硫的必要性：
The necessity of biogas desulfurization:
沼氣脫硫劑是一種安裝在沼氣脫硫器內(nèi)的顆粒狀、可以通過(guò)化學(xué)反應(yīng)去除硫化氫的物質(zhì)。它的作用是除去從沼氣池中輸送來(lái)的硫化氫氣體，該氣體具有臭雞蛋味，沼氣通過(guò)脫硫劑吸收過(guò)濾就可去掉這種臭味，變成真正的安全和干凈的沼氣燃料。否則，含有硫化氫的沼氣燃燒后會(huì)變成二氧化硫等氣體，不但對(duì)人的器官造成危害，還會(huì)腐蝕沼氣灶、炊具、發(fā)電機(jī)組等設(shè)備，縮短這些設(shè)備的使用壽命，增加故障率等。所以，及時(shí)更換脫硫劑是正確使用沼氣的重要措施。
Biogas desulfurizer is a granular substance installed in a biogas desulfurizer that can remove hydrogen sulfide through chemical reactions. Its function is to remove the hydrogen sulfide gas transported from the biogas digester, which has a foul egg odor. The biogas can be absorbed and filtered by desulfurization agents to remove this odor and become a truly safe and clean biogas fuel. Otherwise, biogas containing hydrogen sulfide will become sulfur dioxide and other gases after combustion, not only causing harm to human organs, but also corroding equipment such as biogas stoves, cooking utensils, and power generators, shortening the service life of these equipment and increasing the failure rate. Therefore, timely replacement of desulfurizers is an important measure for the correct use of biogas.
脫硫劑的使用方法：
Method of using desulfurizer:
根據(jù)沼氣脫硫劑使用的實(shí)際情況，一般使用3-6個(gè)月必須更換。首先關(guān)閉沼氣脫硫塔的開關(guān)，打開沼氣脫硫塔進(jìn)出料口，將脫硫劑掏凈，關(guān)閉出料口，在進(jìn)料口填裝新脫硫塔，填滿后封閉進(jìn)料口。 更換下的脫硫劑還可再次使用，方法是：將更換下來(lái)的脫硫劑先除去碎沫和雜物等，再把顆粒型劑放在陰涼、通風(fēng)、干燥處2-4天，等到脫硫劑的顏色變成褐色之后，用塑料袋密封起來(lái)，不讓其受潮、曝曬、壓碎，等下次更換使用。換下來(lái)的脫硫劑多只能再用兩次，再次使用時(shí)間只能在3-6個(gè)月。
According to the actual situation of using biogas desulfurizers, they must be replaced after 3-6 months of use. Firstly, turn off the switch of the biogas desulfurization tower, open the inlet and outlet of the biogas desulfurization tower, remove the desulfurizer, close the outlet, fill the inlet with a new desulfurization tower, and then close the inlet. The replaced desulfurizer can also be used again. The method is to first remove the broken foam and debris from the replaced desulfurizer, and then place the granular agent in a cool, ventilated, and dry place for 2-4 days. After the color of the desulfurizer turns brown, seal it with a plastic bag to prevent it from getting damp, exposed to sunlight, or crushed, and wait for the next replacement. The replaced desulfurizer can only be reused twice at most, and the reuse time can only be 3-6 months.
