沼氣中含有約萬分之一的硫化氫，隨沼氣燃燒后會生成二氧化碳。當(dāng)溫室中二氧化硫濃度達到極限時，一些對二氧化硫比較敏感的作物有番茄、茄子、菠菜、萵苣等則會使植株組織脫水、死亡。所以在溫室燃燒沼氣時要經(jīng)過脫硫處理。
Biogas contains about one tenth of hydrogen sulfide, which will generate carbon dioxide after combustion with biogas. When the concentration of sulfur dioxide in the greenhouse reaches the limit, some crops sensitive to sulfur dioxide, such as tomato, eggplant, spinach and lettuce, will dehydrate and die the plant tissue. Therefore, it is necessary to undergo desulfurization treatment when burning biogas in greenhouse.
沼氣脫硫是基于沼氣中的硫化氫，硫化氫是一種酸性氣體，無論是對人體還是對環(huán)境、設(shè)備、管道以及儀表等都會產(chǎn)生污染和腐蝕的影響。所以，無論是直接用于燃燒或沼氣發(fā)電，還是為了為延長設(shè)備的使用壽命，在輸氣管路中必須安裝脫硫器，對沼氣進行必要的脫硫、脫碳、脫水、除塵等處理。
Biogas desulfurization is based on hydrogen sulfide in biogas. Hydrogen sulfide is an acidic gas, which will cause pollution and corrosion to human body, environment, equipment, pipelines and instruments. Therefore, whether it is directly used for combustion or biogas power generation, or in order to prolong the service life of the equipment, a desulfurizer must be installed in the gas transmission pipeline to carry out necessary desulfurization, decarbonization, dehydration, dust removal and other treatment of biogas.
氣脫硫器是農(nóng)村戶用沼氣輸氣系統(tǒng)中不可缺少的一種儀器，沼氣脫硫器主要有以下4個作用。
Gas desulfurizer is an indispensable instrument in rural household biogas gas transmission system. Biogas desulfurizer mainly has the following four functions.
（1）脫除沼氣中的硫化氫氣體
(1) Removing hydrogen sulfide gas from biogas
硫化氫對灶具及壓力表和管路具有腐蝕作用，以及燃燒不完全帶來的異味而造成污染環(huán)境，脫除沼氣中的硫化氫氣體可以避免以上問題的出現(xiàn)。
Hydrogen sulfide corrodes the stove, pressure gauge and pipeline, and pollutes the environment due to the peculiar smell caused by incomplete combustion. Removing hydrogen sulfide gas from biogas can avoid the above problems.
（2）顯示壓強
(2) Display pressure
有的沼氣脫硫器上面會附有一個壓力表，壓力表顯示的數(shù)字就是沼氣池中的壓強大小。
Some biogas desulfurizers will be attached with a pressure gauge, and the number displayed by the pressure gauge is the pressure in the biogas digester.
（3）開、關(guān)氣體通道
(3) Open and close the gas channel
可以根據(jù)需要打開或關(guān)閉氣體通道。
The gas channel can be opened or closed as required.
（4）防止氣體回流
(4) Prevent gas backflow
脫硫器具有防止氣體回流，以免回火發(fā)生。
The desulfurizer can prevent gas backflow to avoid tempering.
沼氣中含有少量的硫化氫氣體。硫化氫的存在，不僅對人體有害，更是一種酸性氣體，對管道、開關(guān)閥門、儀表、沼氣燈和灶具的電子點火裝置等都具有很強的腐蝕性，對家用電器也有腐蝕作用。因此，在輸氣管道中安裝沼氣脫硫器，可以很好的保證我們安全用氣，還能夠延長設(shè)備的使用壽命。
Biogas contains a small amount of hydrogen sulfide gas. The existence of hydrogen sulfide is not only harmful to human body, but also an acidic gas. It has strong corrosivity to pipelines, on-off valves, instruments, biogas lamps and electronic ignition devices of stoves, as well as household appliances. Therefore, the installation of biogas desulfurizer in the gas transmission pipeline can not only ensure our safe use of gas, but also prolong the service life of the equipment.
