　　The material selection of biogas dry desulfurization equipment directly affects the equipment life and desulfurization stability. The core materials are divided into two categories: equipment main body material and desulfurizer material.

　　（一）設(shè)備主體材質(zhì)

　?。?） Equipment body material

　　1.主流材質(zhì)：以碳鋼、不銹鋼（如304不銹鋼）、玻璃纖維增強塑料（FRP）為主 。其中不銹鋼材質(zhì)因耐腐蝕性能優(yōu)異，在中高端設(shè)備中應(yīng)用廣泛，如普新20L脫硫器便采用304不銹鋼鑄造；碳鋼需經(jīng)防銹防腐處理，適用于預(yù)算有限的中小型項目；玻璃鋼則兼具耐腐蝕性與輕量化特點，適合潮濕環(huán)境。

　　1. Mainstream materials: mainly carbon steel, stainless steel (such as 304 stainless steel), and fiberglass reinforced plastic (FRP). Stainless steel material is widely used in mid to high end equipment due to its excellent corrosion resistance. For example, the Puxin 20L desulfurizer is made of 304 stainless steel casting; Carbon steel needs to undergo rust and corrosion prevention treatment, suitable for small and medium-sized projects with limited budgets; Fiberglass has both corrosion resistance and lightweight characteristics, making it suitable for humid environments.

　　2.標(biāo)準要求：根據(jù)NY/T 4064-2021標(biāo)準，塔體耐壓壓力不得小于10kPa，最小壁厚依材質(zhì)不同分別為1mm（玻璃鋼）、2mm（不銹鋼）、4mm（碳鋼），且在10kPa壓力下24小時壓力變化應(yīng)小于試驗壓力的3%。

　　2. Standard requirements: According to NY/T 4064-2021 standard, the pressure resistance of the tower body shall not be less than 10kPa, and the minimum wall thickness shall be 1mm (fiberglass), 2mm (stainless steel), and 4mm (carbon steel) depending on the material. The pressure change within 24 hours under 10kPa pressure shall be less than 3% of the test pressure.

　　3.輔助部件材質(zhì)：進出氣管、閥門等接觸沼氣的部件多采用耐腐蝕塑料（如聚丙烯PP、聚乙烯PE）或不銹鋼，確保氣體輸送過程無泄漏、無腐蝕 。

　　3. Material of auxiliary components: Components such as inlet and outlet pipes, valves, etc. that come into contact with biogas are often made of corrosion-resistant plastics (such as polypropylene PP, polyethylene PE) or stainless steel to ensure no leakage or corrosion during gas transportation.

The regenerated desulfurizer is screened to remove powder and then refilled. 3. Integrated structure: Some equipment integrates dehydration, filtration, and desulfurization functions, such as a 250 liter integrated desulfurization and dehydration equipment, reducing system footprint and installation complexity.

　?。ǘ┫到y(tǒng)銜接流程

　　（2） System connection process

　　沼氣從厭氧發(fā)酵裝置產(chǎn)出后，經(jīng)水封與氣柜緩存，由風(fēng)機加壓進入干法脫硫系統(tǒng)，凈化后（H?S≤50ppm）可直接用于發(fā)電，或進入脫碳、壓縮單元制備生物天然氣。五工作原理

　　After biogas is produced from anaerobic fermentation equipment, it is sealed with water and stored in a gas tank. It is pressurized by a fan and enters the dry desulfurization system. After purification (H ? S ≤ 50ppm), it can be directly used for power generation or enter decarbonization and compression units to prepare biogas. Five working principles

　　干法脫硫基于“干式氧化法”原理，通過固體脫硫劑的化學(xué)吸附或催化氧化作用去除硫化氫，核心分為反應(yīng)與再生兩個階段。

　　Dry desulfurization is based on the principle of "dry oxidation method", which removes hydrogen sulfide through chemical adsorption or catalytic oxidation of solid desulfurizer. The core is divided into two stages: reaction and regeneration.

　　（一）核心反應(yīng)過程

　?。?） Core reaction process

　　1.氧化鐵脫硫劑：通過化學(xué)反應(yīng)實現(xiàn)脫硫，氧化鐵（Fe?O?）與硫化氫（H?S）反應(yīng)生成硫化鐵（Fe?S?），反應(yīng)式為Fe?O? + 3H?S = Fe?S? + 3H?O，當(dāng)脫硫劑由棕紅色變?yōu)楹谏珪r表明接近飽和 。2.活性炭脫硫劑：依靠物理吸附作用捕獲硫化氫分子，適合處理濃度低于1000ppm的沼氣，吸附飽和后需高溫再生 。3.復(fù)合型脫硫劑：兼具化學(xué)反應(yīng)與物理吸附雙重機制，部分硫化氫與氧化鐵反應(yīng)，部分直接轉(zhuǎn)化為單質(zhì)硫，脫硫精度可達99%。

　　1. Iron oxide desulfurizer: desulfurization is achieved through chemical reactions, where iron oxide (Fe ? O3) reacts with hydrogen sulfide (H ? S) to form iron sulfide (Fe ? S3). The reaction equation is Fe ? O3+3H ? S=Fe ? S3+3H ? O. When the desulfurizer changes from brownish red to black, it indicates near saturation. 2. Activated carbon desulfurizer: It relies on physical adsorption to capture hydrogen sulfide molecules and is suitable for treating biogas with a concentration below 1000ppm. After adsorption saturation, it needs to be regenerated at high temperature. 3. Composite desulfurizer: It has a dual mechanism of chemical reaction and physical adsorption. Some hydrogen sulfide reacts with iron oxide, and some is directly converted into elemental sulfur. The desulfurization accuracy can reach 99%.

　?。ǘ┟摿騽┰偕鷻C制

　?。?） Regeneration mechanism of desulfurizer

　　氧化鐵脫硫劑飽和后可離線再生，通過撒水并接觸空氣，使硫化鐵氧化為氧化鐵和單質(zhì)硫，再生溫度控制在70℃以下，可再生次數(shù)不超過3次；活性炭則需通過高溫（200~300℃）解析再生，恢復(fù)吸附能力 。六產(chǎn)品耗材

　　After saturation with iron oxide desulfurizer, it can be regenerated offline by sprinkling water and contacting with air to oxidize iron sulfide into iron oxide and elemental sulfur. The regeneration temperature is controlled below 70 ℃, and the number of regenerations does not exceed 3 times; Activated carbon needs to be regenerated through high-temperature (200-300 ℃) decomposition to restore its adsorption capacity. Six product consumables

　　耗材成本是設(shè)備運行的主要支出，核心為脫硫劑，輔助耗材占比極低。

　　The cost of consumables is the main expense for equipment operation, with the core being desulfurizers and the proportion of auxiliary consumables being extremely low.

　　（一）核心耗材：脫硫劑

　?。?） Core consumables: desulfurizer

　　1.類型與用量：主流為氧化鐵脫硫劑，單塔裝填量依處理規(guī)模而定，如20L脫硫器配置18公斤脫硫劑；活性炭脫硫劑用量需根據(jù)吸附容量計算，通常比氧化鐵高20%~30%。2.更換周期：受硫化氫濃度、處理量影響，常規(guī)工況下氧化鐵脫硫劑更換周期約6個月，高濃度場景（H?S＞2%）需縮短至1~2個月，可通過公式T=1000ρVf/(2167QCs)精確計算（T為更換時間，Q為產(chǎn)氣量，Cs為硫化氫含量）。3.成本區(qū)間：氧化鐵脫硫劑單價約1.5~3元/公斤，活性炭約8~15元/公斤，中小型項目年耗材成本通常在5000~2萬元 。

　　1. Type and dosage: The mainstream is iron oxide desulfurizer, and the loading capacity of a single tower depends on the processing scale. For example, a 20L desulfurizer is equipped with 18kg of desulfurizer; The dosage of activated carbon desulfurizer needs to be calculated based on the adsorption capacity, usually 20% to 30% higher than that of iron oxide. 2. Replacement cycle: Due to the influence of hydrogen sulfide concentration and processing capacity, the replacement cycle of iron oxide desulfurizer under normal working conditions is about 6 months. In high concentration scenarios (H ? S>2%), it needs to be shortened to 1-2 months, which can be accurately calculated by the formula T=1000 ρ Vf/(2167QCs) (T is the replacement time, Q is the gas production, Cs is the hydrogen sulfide content). 3. Cost range: The unit price of iron oxide desulfurizer is about 1.5-3 yuan/kg, activated carbon is about 8-15 yuan/kg, and the annual consumable cost of small and medium-sized projects is usually 50-20000 yuan.

　　（二）輔助耗材

　?。?） Auxiliary consumables

Adaptation reasons: Small processing capacity (5-20m ?/h), moderate hydrogen sulfide concentration (0.5%~1%), low equipment investment (30000~50000 yuan/set), easy maintenance, suitable for agricultural project needs. 3. Typical case: Biogas from pig farms is used for on-site heating, equipped with single tower dry desulfurization equipment, with a desulfurization efficiency of over 95%.

　　1. Applicable scenarios: Industrial organic wastewater anaerobic treatment projects such as distilleries, paper mills, and food processing plants. 2. Adaptation reason: It can handle medium-sized biogas (20~50m ?/h), and some industrial scenarios require deep desulfurization (H ? S ≤ 50ppm) to protect power generation equipment. The "dry coarse desulfurization+fine desulfurization" series process is adopted. 3. Technical requirements: It is necessary to adapt to the characteristics of large fluctuations in biogas composition, and some equipment should be equipped with automatic adjustment systems.

　　1. Applicable scenarios: biogas recovery in sewage treatment plants, biogas treatment in small landfill sites. 2. Adaptation reasons: Strict environmental requirements, dry desulfurization without secondary pollution, can be connected with subsequent biological natural gas purification systems; The biogas humidity in the sewage treatment plant is high, and the equipment needs to strengthen drainage design. 3. Limitations: Large scale landfill sites (with biogas capacity>100m ?/h) usually use wet methods as the main method due to high hydrogen sulfide concentration (>3%), with dry methods as a supplement for refined desulfurization.
