    碱法生物脱硫的原理是什么？

    工艺原理：

    Process principle:
    在脱硫塔内，小蝌蚪www网在线官网下载中的硫化氢和氢氧化钠进行中和反应，反应后的产物为硫氢化钠和水，去除小蝌蚪www网在线官网下载中的硫化氢；然后再利用生物菌的作用，将硫氢化钠还原成氢氧化钠和单质硫。
    In the desulfurization tower, the hydrogen sulfide and sodium hydroxide in the biogas are neutralized, and the reaction product is sodium hydrogen sulfide and water to remove the hydrogen sulfide in the biogas; Then, sodium hydrosulfide is reduced to sodium hydroxide and elemental sulfur by using the role of biological bacteria.
    步：脱硫反应塔内的化学方程式：
    Step 1: Chemical equation in desulfurization reaction tower:
    H2S(G) + OH -   → HS(L) + H2O
    H2S(G) + OH -   → HS(L) + H2O
    第二步：再生池内的化学方程式：
    Step 2: Chemical equation in regeneration tank:
    HS(L) + 1/2O2 → S  +  OH-
    HS(L) + 1/2O2 → S  +  OH-
    运行过程：
    Operation process:
    小蝌蚪www网在线官网下载通过脱硫反应塔将小蝌蚪www网在线官网下载中H2S从气相转化成液相，脱硫反应塔就是一个洗涤塔。小蝌蚪www网在线官网下载从塔底部进入并穿过滤料床。循环水从塔顶进入，经过专用喷头打散，自由落体穿过滤床，专用滤料可以使小蝌蚪www网在线官网下载与循环水进一步打散和延长接触时间，提高洗涤效果。含有硫化物的循环水从脱硫反应塔底部流入再生池。
    生物脱硫
    The biogas converts H2S in the biogas from the gas phase to the liquid phase through the desulfurization reaction tower, which is a scrubber. The biogas enters from the bottom of the tower and passes through the filter bed. The circulating water enters from the top of the tower, disperses through the special nozzle, and the free falling body passes through the filter bed. The special filter material can further disperse the biogas and the circulating water, extend the contact time, and improve the washing effect. Circulating water containing sulfide flows into regeneration tank from the bottom of desulfurization reaction tower.
    再生池完成循环水中硫化物被氧化的过程，再生池内创造循环水中脱硫菌的生存环境，再生池内的加热盘管给循环水提供热量，保证循环水温度在30-33度之间。曝气头给循环水提供氧气，保证循环水适当的溶解氧。
    The regeneration tank completes the process of sulfide oxidation in the circulating water. The regeneration tank creates a living environment for desulfurization bacteria in the circulating water. The heating coil in the regeneration tank provides heat for the circulating water to ensure that the temperature of the circulating water is between 30-33 degrees. The aerator provides oxygen to the circulating water to ensure proper dissolved oxygen in the circulating water.

    工艺特点：
    Process characteristics:
    ①脱硫过程中除向再生池通入少量空气外和少量碱液，不需再额外添加催化剂和氧化剂；
    ① In addition to a small amount of air and a small amount of lye into the regeneration tank during the desulfurization process, no additional catalyst and oxidant need to be added;
    ②不需处理化学污泥；
    ② No need to treat chemical sludge;
    ③产生很少生物污染，低能耗，效率高且稳定，无臭味；
    ③ It produces little biological pollution, low energy consumption, high efficiency and stability, and no odor;
    ④技术含量高，但易控制，只需要对操作人员进行一周培训（高中文化）。
    ④ High technical content, but easy to control, only one week of professional training (high school culture) is required for operators.
