沼气脱硫剂是一种颗粒状物质。它的作用是除去从沼气池中输送来的沼气中的硫化氢气体，硫化氢气体具有臭鸡蛋味，通过脱硫剂吸收过滤就可去掉这种臭味，变成真正的沼气燃料。
Biogas desulfurizer is a granular material. Its function is to remove the hydrogen sulfide gas from the biogas transported from the biogas digester. The hydrogen sulfide gas has the odor of rotten eggs. The odor can be removed by the absorption and filtration of desulfurizer and turned into real biogas fuel.
否则，含有硫化氢气体的沼气烧饭燃烧后硫化氢将会变成二氧化硫气体不但对人体有害而且在炒菜、点灯时还能闻到刺鼻二氧化硫气味，对人的器官造成危害，污染空气，还会腐蚀沼气灶、炊具等，所以，要及时更换脱硫剂是正确使用沼气的重要措施。
Otherwise, hydrogen sulfide containing hydrogen sulfide gas will become sulfur dioxide gas after cooking, which will not only be harmful to human body, but also can smell the pungent smell of sulfur dioxide when cooking and lighting. It will cause harm to human organs, pollute the air, and corrode biogas stoves and cooking utensils. Therefore, it is necessary to replace the desulfurizer in time. Important measures for correct use of biogas.
