    石膏法煙氣脫硫的原理介紹！

    鍋爐/窯爐—>除塵器—>引風機—>吸收塔—>煙囪來自於鍋爐或窯爐的煙氣經過除塵後在引風機作用下進入吸收塔，吸收塔為逆流噴淋空塔結構，集吸收、氧化功能於一體，上部為吸收區，下部為氧化區，經過除塵後的煙氣與吸收塔內的循環漿液逆向接觸。
    Boiler/Kiln ->Dust Remover ->Induced Draft Fan ->Absorption Tower ->Chimney The flue gas from the boiler or kiln enters the absorption tower under the action of the induced draft fan after being removed from the dust. The absorption tower is a countercurrent spray empty tower structure that integrates absorption and oxidation functions. The upper part is an absorption zone, and the lower part is an oxidation zone. The flue gas after dust removal is in reverse contact with the circulating slurry in the absorption tower.
    係統一般裝3-5台漿液循環泵，每台循環泵對應一層霧化噴淋層。當隻有一台機組運行時或負荷較小時，可以停運1-2層噴淋層，此時係統仍保持較高的液氣比，從而可達到所需的脫硫效果。吸收區上部裝二級除霧器，除霧器出口煙氣中的遊離水份不超過75mg/Nm3
    The system is generally equipped with 3-5 slurry circulating pumps, each of which corresponds to a layer of atomization spray layer. When only one unit is operating or the load is low, 1-2 layers of spray layers can be shut down, while the system still maintains a high liquid gas ratio to achieve the desired desulfurization effect. A two-stage mist eliminator is installed at the upper part of the absorption zone, and the free water content in the flue gas at the outlet of the mist eliminator does not exceed 75mg/Nm3\
    生物脫硫
    吸收SO2後的漿液進入循環氧化區，在循環氧化區中，亞硫酸鈣被鼓入的空氣氧化成石膏晶體。同時，由吸收劑製備係統向吸收氧化係統供給新鮮的石灰石漿液，用於補充被消耗掉的石灰石，使吸收漿液保持一定的pH值。反應生成物漿液達到一定密度時排脫硫副產品係統，經過脫水形成石膏。
    The slurry after absorbing SO2 enters the circulating oxidation zone, where calcium sulfite is oxidized into gypsum crystals by the blown air. At the same time, the absorbent preparation system supplies fresh limestone slurry to the absorption oxidation system to supplement consumed limestone and maintain a certain pH value of the absorption slurry. When the reaction product slurry reaches a certain density, it is discharged to the desulfurization by-product system and dehydrated to form gypsum.
