鑒于化石燃料枯竭危機，生物質(zhì)燃料的開發(fā)和應(yīng)用已成為關(guān)注的焦點。其中，沼氣作為可再生能源，具有利用成本低，對環(huán)境沒污染的特點。它們是高質(zhì)量的環(huán)保燃料，可替代傳統(tǒng)的化石能源。隨著大型沼氣和沼氣項目的迅速發(fā)展，對用于高附加值沼氣的沼氣凈化提純設(shè)備的需求日益迫切。沼氣凈化技術(shù)已得到不同程度的應(yīng)用和發(fā)展。
In view of the crisis of fossil fuel depletion, the development and application of biomass fuel has become the focus of attention. As a renewable energy, biogas has the characteristics of low cost and no pollution to the environment. They are high-quality environmental protection fuels, which can replace the traditional fossil energy. With the rapid development of large-scale biogas and biogas projects, the demand for biogas purification equipment for high value-added biogas is increasingly urgent. Biogas purification technology has been applied and developed in different degrees.
厭氧反應(yīng)會產(chǎn)生沼氣，通常含有一定量的硫化氫。不同工業(yè)廢水中沼氣中硫化氫的含量不同。如果硫化氫的含量過高，則在進入鍋爐之前必須去除沼氣中的硫化氫，以免腐蝕管道和鍋爐。您對沼氣凈化提純設(shè)備的這些特性是否足夠清楚？
Anaerobic reaction will produce biogas, usually containing a certain amount of hydrogen sulfide. The content of hydrogen sulfide in biogas is different in different industrial wastewater. If the content of hydrogen sulfide is too high, hydrogen sulfide in biogas must be removed before entering the boiler to avoid corrosion of pipes and boilers. Are you clear enough about these characteristics of biogas purification equipment?
這是一種使用生物菌株從沼氣中去除高腐蝕性和劇毒硫化氫氣體的方法。該工藝具有自動化程度高，工藝簡單，運行成本低的優(yōu)點。厭氧發(fā)酵產(chǎn)生的沼氣進入洗滌塔，并與基本循環(huán)噴霧器吸收反應(yīng)，以從沼氣中去除硫化氫。從富液吸收的硫化氫返回到生物反應(yīng)器。生物轉(zhuǎn)化后，將硫化氫轉(zhuǎn)化為固體硫，并將溶液再生為堿性吸收液，可用于洗滌沼氣，然后完成吸收劑的循環(huán)利用。硫固體的分離通過硫沉淀器完成。
This is a method of using biological strains to remove highly corrosive and toxic hydrogen sulfide gas from biogas. The process has the advantages of high automation, simple process and low operation cost. The biogas generated by anaerobic fermentation enters the washing tower and absorbs reaction with the basic circulation sprayer to remove hydrogen sulfide from the biogas. The hydrogen sulfide absorbed from the rich liquid is returned to the bioreactor. After biotransformation, hydrogen sulfide is converted into solid sulfur, and the solution is regenerated into alkaline absorption solution, which can be used to wash biogas, and then recycle the absorbent. The separation of sulfur solids is accomplished by sulfur precipitator.
沼氣凈化提純設(shè)備將弱堿性條件下硫化氫的物理和化學吸收與空氣中堿性溶液的生物再生相結(jié)合。沒有硫化氫的沼氣從洗滌塔頂部逸出，含有硫化氫的溶液流入生物反應(yīng)器。在限制氧氣供應(yīng)的條件下，它被氧化成元素硫和堿。少量廢水和副產(chǎn)物硫不含硫化物，可以直接排放。
Biogas purification equipment combines physical and chemical absorption of hydrogen sulfide under weak alkaline conditions with biological regeneration of alkaline solution in air. The biogas without hydrogen sulfide escapes from the top of the scrubber, and the solution containing hydrogen sulfide flows into the bioreactor. Under the condition of limited oxygen supply, it is oxidized to elemental sulfur and alkali. A small amount of waste water and by-product sulfur do not contain sulfide and can be directly discharged.
