Description
技术领域
[0001]本实用新型涉及一种烟气净化装置，特别涉及一种烟气脱硫除尘一体装置。
背景技术
[0002]企业生产过程中，燃料燃烧和生产工艺过程中产生各种含有污染物的气体，如果直接排入大气，将会污染空气，影响人类及动植物的生命安全。特别是其中的粉尘和硫化物，危害十分严重。
[0003]目前的烟气脱硫装置为单向通道，适用于含硫量较低的烟气净化，当烟气中的含硫量较高时，为满足排放要求，通常需要串联两个或多个脱硫装置，而多个脱硫装置造成占地面积增大、投资成本高，能耗高。
[0004]常规的湿法脱硫系统在脱硫的同时，具有一定的除尘效果，然而其除尘功能有限，出口粉尘往往难以达标，为此，通常在上游降低脱硫吸收塔入口粉尘浓度，或者在下游增加单独的除尘系统，这两种方式都需要增加额外用地，导致占地面积大，投资费用高。
实用新型内容
[0005]根据以上现有技术的不足，本实用新型所要解决的技术问题是:提供一种烟气脱硫除尘一体装置，实现烟气脱硫除尘一体化，脱硫及除尘效率高，占地面积小，节省投资。
[0006]本实用新型所述的烟气脱硫除尘一体装置，包括塔体，塔体底部设有浆液池，浆液池上方设有并列的第一塔体、第二塔体，第一塔体由上到下依次设置第一喷淋层、第一通道挡板、第二喷淋层、第二通道挡板，第一喷淋层、第二喷淋层通过第一循环栗连接浆液池，烟气入口设置在第一塔体上端;第二塔体由下到上依次设置空心球填料层、入口除雾器、第一旋流板、第三喷淋层、第二旋流板、第四喷淋层、水膜除尘层及出口除雾器，第三喷淋层、第四喷淋层通过第二循环栗连接浆液池，第二塔体上端设置烟气出口。
[0007]通过设置第一塔体、第二塔体，使烟气依次进入两个塔体内，增强了脱硫除尘效果，同时节省占地面积，降低投资成本，通过第一通道挡板、第二通道挡板延长了对烟气的喷淋时间和距离，从而加强了脱硫除尘效果。通过入口除雾器降低烟气的总含固量，出口除雾器降低液滴排放浓度，气流通过旋流板产生旋转和离心运动，吸收液形成薄液层，与旋转向上的气流形成旋转和离心的效果，喷成细小液滴，甩向塔壁，进一步降低烟气中的含硫及含尘量。
[0008]所述的第一通道挡板、第二通道挡板上表面设置为坡面，坡面的低点与内侧塔壁之间留出烟气通过口，通过坡面延长烟气的行进长度，从而延长喷淋时间。
[0009]所述坡面的倾角小于30°。
[0010]所述的浆液池两侧分别设置第一搅拌器、第二搅拌器。
[0011 ]所述的浆液池连接浆液补充管及排放管。
[0012]所述的浆液池设有脱硫剂补充管。
[0013]所述的第一塔体、第二塔体形成U形结构。
[0014]烟气首先进入前脱硫区，由烟气入口进入第一塔体，并依次沿第一通道挡板、第二通道挡板坡面向下，第一喷淋层、第二喷淋层喷出浆液，吸收烟气中的SO2、SO3后落入下方的浆液池中。
[0015]烟气经第一塔体脱硫后进入第二塔体的后脱硫区，依次经空心球填料层、入口除雾器降低烟气的总含固量，第一旋流板、第三喷淋层、第二旋流板、第四喷淋层、水膜除尘层进一步去除烟气中的S02、S03及尘粒，出口除雾器降低液滴排放浓度，经净化后的烟气由烟气出口排出。
[0016]与现有技术相比，本实用新型具有的有益效果是:
[0017]本烟气脱硫除尘一体装置，实现烟气脱硫除尘一体化，脱硫及除尘效率高，设备占地面积小，投资低，能耗低。
附图说明
[0018]图1是本实用新型结构不意图。
[0019]图中:1、第一喷淋层;2、烟气入口；3、第一通道挡板;4、第二喷淋层;5、第一塔体；
6、第一循环栗;7、脱硫剂补充管;8、第一搅拌器;9、排放管；10、浆液池；11、第二通道挡板；12、第二搅拌器；13、浆液补充管；14、第二循环栗；15、空心球填料层;16、入口除雾器;17、第一旋流板；18、第三喷淋层；19、第二旋流板;20、第四喷淋层;21、水膜除尘层;22、出口除雾器;23、烟气出口；24、第二塔体。
具体实施方式
[0020]下面结合附图对本实用新型的实施例做进一步描述。
[0021]如图1所示，本烟气脱硫除尘一体装置包括塔体，塔体底部设有浆液池10，浆液池10上方设有并列的第一塔体5、第二塔体24，第一塔体5、第二塔体24形成U形结构，两者底部均与浆液池10相通，第一塔体5内设置前脱硫区，第二塔体24内设置后脱硫除尘区，烟气入口 2设置在第一塔体5上端，烟气出口 23设置在第二塔体24上端。
[0022]第一塔体5由上到下依次设置第一喷淋层1、第一通道挡板3、第二喷淋层4、第二通道挡板11，第一喷淋层1、第二喷淋层4通过第一循环栗6连接浆液池10;第一通道挡板3、第二通道挡板11上表面设置为坡面，坡面的低点与内侧塔壁之间留出烟气通过口，坡面的倾角小于30° ο设置两层挡板，烟气首先沿第一通道挡板3的坡面前进，通过烟气通过口进入下方，再沿第二通道挡板11的坡面前进，通过两层挡板及坡面，延长了烟气经过的时间，从而增强了脱硫效果。
[0023]第二塔体24由下到上依次设置空心球填料层15、入口除雾器16、第一旋流板17、第三喷淋层18、第二旋流板19、第四喷淋层20、水膜除尘层21及出口除雾器22，通过入口除雾器16降低烟气的总含固量，出口除雾器22降低液滴排放浓度，气流通过旋流板产生旋转和离心运动，吸收液形成薄液层，与旋转向上的气流形成旋转和离心的效果，喷成细小液滴，甩向塔壁，进一步降低烟气中的含硫及含尘量。第三喷淋层18、第四喷淋层20通过第二循环栗14连接浆液池10。
[0024]浆液池10两侧分别设置第一搅拌器8、第二搅拌器12，搅拌器为叶轮搅拌，防止硫化物沉淀。浆液池10还连接浆液补充管13、排放管9及脱硫剂补充管7，可根据情况补充脱硫剂及新鲜浆液。
[0025] 工作过程:
[0026]烟气首先进入前脱硫区，由烟气入口 2进入第一塔体5，并依次沿第一通道挡板3、第二通道挡板11坡面向下，第一喷淋层1、第二喷淋层4喷出浆液，吸收烟气中的SO2、SO3后落入下方的浆液池10中。
[0027]烟气经第一塔体5脱硫后进入第二塔体24的后脱硫区，依次经空心球填料层15、入口除雾器16降低烟气的总含固量，第一旋流板17、第三喷淋层18、第二旋流板19、第四喷淋层20、水膜除尘层21进一步去除烟气中的S02、S03及尘粒，出口除雾器22降低液滴排放浓度，经净化后的烟气由烟气出口 23排出。
