水泥厂脱硝系统工艺流程
    英文回答：
    Cement Plant Denitration System Process Flow.
    1. Limestone Crushing and Preparation.
    Limestone, typically obtained from nearby quarries, is crushed into smaller pieces to increase its surface area and reactivity. The crushed limestone is then transported to the denitrification reactor.
    2. Raw Material Preheating.
    The crushed limestone and coal, used as the primary fuel, are preheated in a preheater to raise their temperature and enhance the denitrification efficiency.
    3. Calcination and Clinker Formation.
    The preheated materials enter a kiln, where the limestone decomposes to form calcium oxide (CaO) and releases carbon dioxide (CO2). The CaO then reacts with clay and other raw materials to form cement clinker.
    4. Denitrification Reactor.
    The cement clinker and hot gases are directed to a denitrification reactor, where ammonia (NH3) is injected. The ammonia reduces the nitrogen oxides (NOx) in the flue gases to nitrogen gas (N2) and water vapor.
    5. Burnout Zone.
    After the denitrification reaction, the gases pass through a burnout zone to ensure complete combustion and decomposition of any remaining ammonia.
    6. Bag Filter.
    The flue gases are further cleaned in a bag filter to remove any particulate matter and dust.
    7. Heat Exchanger.
    The flue gases are cooled down in a heat exchanger, recovering heat for use in other processes within the cement plant.
    8. Scrubber.
    The cooled flue gases are passed through a scrubber, which uses lime or other alkaline reagents to remove any remaining acidic gases and pollutants.
    9. Stack.
    The cleaned flue gases are released into the atmosphere through a stack.

    水泥厂脱硝系统工艺流程。
    1. 石灰石破碎及制备。
    从附近采石场获取的石灰石被破碎成小块以增加其比表面积和反应活性。破碎后的石灰石然后被输送到脱硝反应器中。
    2. 原料预热。
    破碎的石灰石和作为主要燃料的煤在预热器中预热，以提高其温度，提高脱硝效率。

    3. 煅烧和熟料形成。
    预热后的物料进入窑中进行煅烧，石灰石分解形成氧化钙（CaO）并释放出二氧化碳 (CO2)。然后，CaO 与粘土和其他原材料反应形成水泥熟料。
    4. 脱硝反应器。
    水泥熟料和热气体被导入脱硝反应器中，其中注入氨 (NH3)。氨将烟气中的氮氧化物 (NOx) 还原为氮气 (N2) 和水蒸气。
    5. 燃烧区。
    在脱硝反应完成后，气体通过燃烧区以确保完全燃烧和分解任何残留的氨。
    6. 布袋除尘器。
    烟气在布袋除尘器中进一步净化以去除任何颗粒物和粉尘。
    7. 热交换器。
    烟气在热交换器中冷却，回收热量以用于水泥厂内的其他工艺。
    8. 洗涤塔。
    冷却后的烟气通过洗涤塔，使用石灰或其他碱性试剂去除任何残留的酸性气体和污染物。
    9. 烟囱。
    净化后的烟气通过烟囱释放到大气中。
