硫化氫的危害性：沼氣內(nèi)的硫化氫,不但腐蝕管道及設(shè)備，更重要的是使人硫化氫中毒。給人們的身體健康造成危害，嚴(yán)重時可以致人死亡。
The harm of hydrogen sulfide: Hydrogen sulfide in biogas not only corrodes pipelines and equipment, but more importantly, causes hydrogen sulfide poisoning in humans. Causing harm to people's physical health, and in severe cases, it can lead to death.
根據(jù)科學(xué)性物理性研制出了ZDE-01、ZDE-02、ZDE-03型常溫氧化鐵沼氣精脫硫劑。主要是三氧氣化二鐵(Fe203]，含量為40％，并添加多種助劑，根據(jù)科技技術(shù)制成，是一種適應(yīng)性強(qiáng)的新型沼氣精脫硫劑．具有硫容量大、脫硫精度高、適應(yīng)性強(qiáng)等特點，是目前國內(nèi)脫硫劑市場產(chǎn)品，長期以來深受新老用戶的青睞。

綜上所述，從脫硫塔或脫硫器工藝上需要的裝填量要求，還應(yīng)考慮選用的脫硫劑．根據(jù)脫硫劑的再生反應(yīng)原理,在設(shè)計脫硫塔或脫硫器時可考慮重復(fù)多次自然再生設(shè)計，方便用戶使用時能實現(xiàn)重復(fù)多次再生，可延長l／2的使用時間，從而降低了成本，大大增加了脫硫劑的使用時間，考慮沼氣特殊的氣質(zhì)，在提高脫硫效率的同時，又降低了成本．如果使用我公司的煤氣脫硫劑，可在貴公司脫硫工藝的基礎(chǔ)上，從一般的脫硫劑25％的硫容可增大到35％，從而延長了1／2的使用時間，大大的降低了脫硫成本，能滿足貴公司的脫硫工藝要求．
In summary, in terms of the required loading requirements for the desulfurization tower or desulfurization device process, high-quality desulfurization agents should also be considered. According to the regeneration reaction principle of desulfurization agents, when designing the desulfurization tower or desulfurization device, the design of repeated natural regeneration can be considered, which is convenient for users to achieve repeated regeneration and can extend the usage time by 1/2, thereby reducing costs and greatly increasing the usage time of desulfurization agents, Considering the unique temperament of biogas, while improving desulfurization efficiency, it also reduces costs. If we use our company's coal gas desulfurization agent, the sulfur capacity of the general desulfurization agent can be increased from 25% to 35% based on your company's desulfurization process, thereby extending the usage time by 1/2, greatly reducing desulfurization costs, and fully meeting your company's desulfurization process requirements
常溫氧化鐵脫硫劑的選擇:
Selection of high-quality room temperature iron oxide desulfurization agent:
各生產(chǎn)廠家的企業(yè)標(biāo)準(zhǔn)大不相同，產(chǎn)品性能差異很大，許多生產(chǎn)廠家產(chǎn)品遠(yuǎn)不能達(dá)到行業(yè)要求，所以用戶在選擇脫硫劑時很關(guān)鍵，由于各生產(chǎn)廠家產(chǎn)品三氧化二鐵有效含量不同，脫硫劑的活性差異也很大，而脫硫精度相差甚遠(yuǎn)，增加三氧化二鐵含量可提高脫硫精度，脫硫劑要求硫容高，大于25—35％之間，脫硫精度
The enterprise standards of various manufacturers vary greatly, and the performance of their products varies greatly. Many manufacturers' products are far from meeting industry requirements, so it is crucial for users to choose desulfurizers. Due to the different effective content of iron oxide in their products, the activity of desulfurizers varies greatly, and the desulfurization accuracy varies greatly. Increasing the content of iron oxide can improve the desulfurization accuracy, and desulfurizers require high sulfur capacity, Greater than 25-35%, desulfurization accuracy
耐水性強(qiáng)，磨耗率低，強(qiáng)度適中，孔容大，脫硫劑的還原再生效果要強(qiáng)，一般的脫硫劑再生后活性衰減厲害，再生后基本無活性，而較好的脫硫劑可重復(fù)再生數(shù)次，再生還原時間快等優(yōu)點．
Strong water resistance, low wear rate, moderate strength, large pore volume, and strong reduction and regeneration effect of desulfurizers. Generally, desulfurizers have a significant decrease in activity after regeneration, and have little activity after regeneration. However, better desulfurizers can be regenerated several times and have advantages such as fast regeneration and reduction time
