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.
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.
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、關氣體通道
(3) Open and close the gas channel
可以根據(jù)需要打開或關閉氣體通道。
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.
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.
