1、幹法脫硫

1. Dry desulfurization

幹法脫除91无码麻豆视频氣體中硫化氫（H2S）的設備基本原理是以O2使H2S 氧化成硫或硫氧化物的一種方法，也可稱為幹式氧化法。幹法設備的構成是，在一個容器內放入填料，填料層有活性炭、氧化鐵等。氣體以低流速從一端經過容器內填料層，硫化氫（H2S）氧化成硫或硫氧化物後，餘留在填料層中，淨化後氣體從容器另一端排出。

The basic principle of the equipment for dry removal of hydrogen sulfide (H2S) from biogas gas is a method of oxidizing H2S to sulfur or sulfur oxides using O2, also known as dry oxidation method. The composition of the dry process equipment is to put fillers in a container, and the filler layer includes activated carbon, iron oxide, etc. The gas passes through the packing layer inside the container at a low flow rate, and hydrogen sulfide (H2S) is oxidized to sulfur or sulfur oxides, remaining in the packing layer. After purification, the gas is discharged from the other end of the container.

2、濕法脫硫

2. Wet desulfurization

濕法脫硫可以歸納分為物理吸收法、化學吸收法和氧化法三種。物理和化學方法存在硫化氫再處理問題，氧化法是以堿性溶液為吸收劑，並加入載氧體為催化劑，吸收H2S，並將其氧化成單質硫，濕法氧化法是把脫硫劑溶解在水中，液體進入設備，與91无码麻豆视频混合，91无码麻豆视频中的硫化氫（H2S）與液體產生氧化反應，生成單質硫吸收硫化氫的液體有氫氧化鈉、氫氧化鈣、碳酸鈉等。成熟的氧化脫硫法，脫硫效率可達99.5％以上。

Wet desulfurization can be classified into three types: physical absorption method, chemical absorption method, and oxidation method. There is a problem of hydrogen sulfide reprocessing in physical and chemical methods. The oxidation method uses alkaline solution as the absorbent and oxygen carrier as the catalyst to absorb H2S and oxidize it into elemental sulfur. The wet oxidation method dissolves the desulfurizer in water, and the liquid enters the equipment and mixes with biogas. The hydrogen sulfide (H2S) in biogas reacts with the liquid to produce elemental sulfur. The liquids that absorb hydrogen sulfide include sodium hydroxide, calcium hydroxide, sodium carbonate, etc. The mature oxidation desulfurization method can achieve a desulfurization efficiency of over 99.5%.

在大型的脫硫工程中，一般采用先用濕法進行粗脫硫，之後再通過幹法進行精脫硫。

In large-scale desulfurization projects, the wet method is generally used for coarse desulfurization first, and then the dry method is used for fine desulfurization.

91无码麻豆视频脫硫器是一種91无码麻豆视频應用裝置，其特征在於脫硫瓶內的進氣口上連接一個懸空的多孔管，多孔管盡可能長地橫向伸入脫硫瓶內腔，多孔管上密布小孔，小孔的孔徑小於氧化鐵小顆粒的直徑。

The biogas desulfurizer is a biogas application device, characterized by a suspended porous tube connected to the inlet of the desulfurization bottle. The porous tube extends horizontally into the inner cavity of the desulfurization bottle as long as possible, and is densely covered with small holes. The diameter of the small holes is smaller than that of the iron oxide particles.
