参见图2，在此实施例中，旋流片合成体安装在每层旋流式除雾器单元的筒体下部。Referring to Fig. 2, in this embodiment, the swirl sheet composite is mounted on the lower portion of the barrel of each layer of the swirling mist eliminator unit.
在此实施例中，所述旋流片合成体的导流叶片切向为顺时针方向或反时针方向。In this embodiment, the guide vanes of the swirling sheet composite are tangentially clockwise or counterclockwise.
参见图2，在此实施例中，每层旋流式除雾器单元1中每个旋流片合成体下部均有冲洗喷嘴2。Referring to Fig. 2, in this embodiment, each of the swirling demister units 1 has a rinsing nozzle 2 at the lower portion of each of the spirograph assemblies.
在此实施例中，参见图1，所述旋流板除尘除雾器叠加组合体固定在脱硫塔体4内，脱硫塔体4上设有冲洗水接口5。In this embodiment, referring to FIG. 1, the swirling plate dust removing demister superimposing assembly is fixed in the desulfurizing tower body 4, and the desulfurizing tower body 4 is provided with a flushing water interface 5.
在此实施例中，参见图1，所述脱硫塔体4内还设有旋流器单元固定核载梁及活荷载方管支撑3。In this embodiment, referring to FIG. 1, the desulfurization tower body 4 is further provided with a cyclone unit fixed nuclear load beam and a live load square tube support 3.
单元内离心式旋流片合成体的叶片呈平行排列，叶片型式及开孔面积A0与燃煤锅炉工况计算相符确定。The blades of the centrifugal cyclone composite in the unit are arranged in parallel, and the blade type and the opening area A0 are determined in accordance with the calculation of the working conditions of the coal-fired boiler.
具体实施时，通过在活荷载将两层及两层以上旋流板除尘除雾器叠加 组合排列的旋流板除尘除雾器组合体放置其上，用卡件将各个塔筒连接固定。支撑结构尺寸和布置依力学计算确定。制造两层及两层以上旋流板除尘除雾器叠加组合排列的旋流板除尘除雾器组合体的材料一般为不锈钢、玻璃钢、改性PP及聚四氟乙烯，或者两种以上材料的组合。In the specific implementation, the cyclone dust removing and mist eliminator assembly which is arranged by superimposing and arranging two or more layers of the cyclone dust removing and defogger on the live load is placed thereon, and the respective towers are connected and fixed by the card members. The size and arrangement of the support structure are determined by mechanical calculations. The material of the cyclone dust removing and mist eliminator assembly for manufacturing two-layer and two-layer cyclone dust removing and mist eliminator is generally stainless steel, glass reinforced plastic, modified PP and polytetrafluoroethylene, or two or more materials. combination.
本实用新型的工作原理：通过单元内离心式旋流片合成体的气流，在具有一定开孔面积A0的旋流板叶片的导引下产生旋转，由于液体的密度远远大于气体，夹带在气流中的液滴在旋转运动产生的离心力作用下，克服液气之间滑动的摩擦阻力向筒体的内壁作径向沉降运动，接触筒体的内壁而被捕捉，进而相互凝聚形成液膜，并在重力作用下沿筒体的内壁流下，以较大液滴的形式离开旋流板收集器落下，不再被气流夹带，实现气液分离。对于带有粉尘的燃煤锅炉烟气，烟气中的粉尘一般具有亲水性，在除尘过程中粉尘粘附在水中而被一同分离。The working principle of the utility model: the airflow of the centrifugal swirling sheet composite body in the unit is rotated under the guidance of the swirling plate blade having a certain opening area A0, since the density of the liquid is much larger than the gas, the entrainment is Under the centrifugal force generated by the rotary motion, the droplets in the airflow overcome the frictional resistance of the sliding between the liquid and the gas to make a radial subsiding motion toward the inner wall of the cylinder, and are caught by the inner wall of the cylinder, thereby coagulating to form a liquid film. And under the action of gravity, it flows down the inner wall of the cylinder, exits the cyclone collector in the form of larger droplets, and is no longer entrained by the airflow to achieve gas-liquid separation. For dusty coal-fired boiler flue gas, the dust in the flue gas is generally hydrophilic, and the dust adheres to the water and is separated together during the dust removal process.
两层及两层以上旋流板除尘除雾器叠加组合排列的旋流板除雾器组合体是利用气液之间巨大的密度差，通过气流旋转产生的离心力使液粒从气流中分离的，离心力的计算公式显示，质量一定的液粒所受离心力的大小同旋转半径成反比例，半径越大则离心力越小，分离效果就越差。也就是说，直径小的旋流板比直径大的旋流板分离效率高。所以，如果要保证分离效果好，两层及两层以上旋流板除尘除雾器叠加组合排列的旋流板除尘除雾器组合体旋流板的直径就不宜过大。根据我们多年对旋流板离心式雾滴超净收集技术研究经验积累，为保证较高的分离效率，两层及两层以上旋流板除尘除雾器叠加组合排列的旋流板除尘除雾器组合体的筒体直径一般应该控制在1000mm以内。所以过去单个旋流板离心式除雾器绝大多数用在小型化工塔器。The two-layer and two-layer cyclone dust-removing demister superimposed and arranged in the swirling plate defogger assembly utilizes a large density difference between gas and liquid, and the centrifugal force generated by the rotation of the airflow separates the liquid particles from the airflow. The formula for calculating the centrifugal force shows that the centrifugal force of the liquid particle with a certain mass is inversely proportional to the radius of rotation. The larger the radius, the smaller the centrifugal force and the worse the separation effect. That is to say, a swirl plate having a small diameter is more efficient in separation than a swirl plate having a large diameter. Therefore, if the separation effect is to be ensured, the diameter of the swirling plate of the cyclone dust removing and mist eliminator assembly of the two-layer and two-layer cyclone dust removing and mist eliminator stacking combination should not be too large. According to our years of experience in the research of cyclone centrifugal droplet ultra-clean collection technology, in order to ensure high separation efficiency, two-layer and two-layer cyclone dust and demister superimposed combination of swirling plate dust removal and defogging The cylinder diameter of the assembly should generally be controlled within 1000 mm. Therefore, in the past, most of the single cyclone centrifugal mist eliminators were used in small chemical towers.
本具体实施方式应用若干个带有冲洗系统的两级及两级以上旋流板并 列组合体除尘除雾器，能够使除雾效率达到99.99％。In this embodiment, a plurality of two-stage and two-stage swirling plate parallel combination dust removing demister with a flushing system can be used to achieve a demisting efficiency of 99.99%.
以上是本实用新型的优选实施例，本领域普通技术人员还可以在此基础上进行各种变换或改进，在不脱离本实用新型总的构思的前提下，这些变换或改进都应当属于本实用新型要求保护的范围之内。The above is a preferred embodiment of the present invention, and those skilled in the art can also make various changes or improvements on the basis of the present invention. These transformations or improvements should belong to the present application without departing from the general concept of the present invention.
