蜜桃视频中文字幕作為*提供農戶炊用的一種氣體燃料，應有一定的質量指標。硫化氫是一種帶有臭雞蛋味的無色有duqi體，也是蜜桃视频中文字幕中主要的有害成分。它不僅危害人體健康，對廚房金屬器具、蜜桃视频中文字幕用具和管道閥門都有較強的腐蝕作用。因此對於農戶炊用的蜜桃视频中文字幕一定要安裝脫硫器，確保硫化氫的含量淨化到0.02g/m3以下。

As a gas fuel used by farmers for cooking, biogas should have certain quality indicators. Hydrogen sulfide is a colorless and odorless substance with a foul egg odor, and is also a major harmful component in biogas. It not only endangers human health, but also has a strong corrosive effect on kitchen metal appliances, biogas appliances, and pipeline valves. Therefore, for the biogas used by farmers for cooking, it is necessary to install a desulfurizer to ensure that the content of hydrogen sulfide is purified to below 0.02g/m3.

蜜桃视频中文字幕脫硫的方法有濕法和幹法兩種。幹法脫硫具有工藝簡單、成熟可靠和造價低廉等優點。目前家用蜜桃视频中文字幕脫硫基本上采用這種方法。

There are two methods for biogas desulfurization: wet method and dry method. Dry desulfurization has the advantages of simple process, mature and reliable, and low cost. At present, this method is mainly used for household biogas desulfurization.

目前市場上有多種戶用幹式脫硫器商品，內裝質量不等的顆粒狀氧化鐵脫硫劑。氧化鐵脫硫劑一般可反複使用3~4次，但不同質量的使用壽命相差近10倍。盡管農村條件有限，而自製脫硫器和脫硫劑對於農村蜜桃视频中文字幕用戶也是十分必要的。

At present, there are various household dry desulfurizer products on the market, which contain granular iron oxide desulfurizers of varying qualities. Iron oxide desulfurizers can generally be reused 3-4 times, but the service life of different qualities varies by nearly 10 times. Although rural conditions are limited, homemade desulfurizers and desulfurizers are also necessary for rural biogas users.

所示為一種簡易的農戶蜜桃视频中文字幕脫硫器。用兩個去掉底蓋的類似500mL的飲料瓶、內裝一塊鑽有許多ф1~1.5mm小孔的塑料圓片，並蓋有2~3層塑料窗紗疊成的圓墊，再對接、用塑料管膠帶黏合而成圓柱殼體；兩端瓶蓋分別開孔，黏接上塑料管嘴作為蜜桃视频中文字幕進、出口接頭，打開上端出氣口的瓶蓋即可裝卸粉狀或顆粒狀的脫硫劑了。需要說明的是，其使用時要豎立安裝、塑料圓片在底部，蜜桃视频中文字幕有下而上通過。

The shown is a simple household biogas desulfurizer. Two 500mL beverage bottles with bottom caps removed, filled with a plastic disc with many small holes of 1~1.5mm, and covered with 2-3 layers of plastic window screens stacked on a circular pad, are then docked and glued together with plastic tube tape to form a cylindrical shell; Both ends of the bottle caps are opened separately, and plastic pipe nozzles are glued together as biogas inlet and outlet joints. Open the bottle cap at the upper outlet to load and unload powdered or granular desulfurizers. It should be noted that it should be installed vertically, with plastic discs at the bottom, and biogas passing from bottom to top during use.

1、蜜桃视频中文字幕脫硫劑的配製

1. Preparation of biogas desulfurizer

幹法脫硫劑有活性炭、分子篩和氧化鐵等。從使用壽命、運行成本、材料易得和使用簡易便等綜合考慮，目前采用zui多的脫硫劑是氧化鐵。其中常用的配方有如下兩種。

Dry desulfurization agents include activated carbon, molecular sieve, and iron oxide. Taking into account factors such as service life, operating costs, availability of materials, and ease of use, the most commonly used desulfurizer currently is iron oxide. There are two commonly used formulas.

天然沼鐵礦。天然沼鐵礦俗稱“黃土”，一般含0.5%~1%。使用前映均勻噴灑清水，使含水率達到30%~40%。這種沼鐵礦在我國黑龍江省的伊春、天津市的薊縣及北京市的懷柔縣等地均有生產。

Natural biogas iron ore. Natural biogas iron ore, commonly known as "loess", generally contains 0.5% to 1%. Spray water evenly before use to achieve a moisture content of 30% to 40%. This type of biogas iron ore is produced in Yichun, Heilongjiang Province, Jixian, Tianjin City, and Huairou County, Beijing City, and other places in China.

人工氧化鐵。將粒度為0.6~2.4mm的鑄鐵屑（或鐵屑）和木屑按質量比為1：1摻混，灑水後充分翻曬進行人工氧化；在使用前再摻混0.5%的熟石灰，以調節脫硫劑的pH值達到8~9，並均勻噴灑清水，使含水率達到30%~40%。

Artificial iron oxide. Mix cast iron chips (or iron chips) with wood chips with a particle size of 0.6-2.4mm in a mass ratio of 1:1, sprinkle water, and thoroughly sun dry for artificial oxidation; Before use, mix 0.5% hydrated lime to adjust the pH value of the desulfurizer to 8-9, and evenly spray clean water to achieve a moisture content of 30%~40%.

對於一般的農村蜜桃视频中文字幕而言，采用人工氧化鐵法是zui方便和的。但是，如果有山西省汾陽催化濟廠生產TG型、北京南郊科星淨化劑廠生產的TTL—2型及上海煤氣公司生產的PM型脫硫劑，也可購買使用。其脫硫效果好、使用壽命長。

For general rural biogas, using artificial iron oxide method is convenient and feasible. However, if there are TG type desulfurizers produced by Shanxi Fenyang Catalytic Plant, TTL-2 type desulfurizers produced by Beijing Nanjiao Kexing Purification Plant, and PM type desulfurizers produced by Shanghai Gas Company, they can also be purchased and used. Its desulfurization effect is good and its service life is long.

2．幹式脫硫劑的再生與交換

2. Regeneration and exchange of dry desulfurizers

蜜桃视频中文字幕脫硫劑中氧化鐵為土黃色。當蜜桃视频中文字幕中的硫化氫與氧化鐵接觸起化學反應生成的硫化鐵呈灰黑色時，脫硫劑失去效力，則要再生或更換。將失效的脫硫劑從瓶內倒出，先用清水衝洗以去除由蜜桃视频中文字幕帶來的泥沫，然後攤曬在水泥地麵上並適當翻曬（能噴灑少量的稀氨水），利用空氣中的氧氣將硫化鐵又氧化成氧化鐵。當蜜桃视频中文字幕脫硫劑由灰黑色又變成土黃色時，則再生過程完成。自製的脫硫劑，再生兩次就應更換新的脫硫劑。

The iron oxide in the biogas desulfurizer is soil yellow. When the hydrogen sulfide in biogas comes into contact with iron oxide through a chemical reaction, the resulting iron sulfide turns gray black, and the desulfurizer loses its effectiveness, it needs to be regenerated or replaced. Pour out the ineffective desulfurizer from the bottle, rinse with clean water to remove the mud foam brought by biogas, then spread it on the cement floor and turn it over appropriately (able to spray a small amount of dilute ammonia water), and use oxygen in the air to oxidize iron sulfide back into iron oxide. When the biogas desulfurizer changes from gray black to earthy yellow, the regeneration process is completed. The self-made desulfurizer should be replaced with a new one after being regenerated twice.
