在安装脱硫塔过程中需要注意哪些方面
What aspects should be paid attention to during installation of desulfurization tower
脱硫塔有填料塔、空喷塔和板式塔等型式。常用的型式是填料塔,由圆形塔体和堆放在塔内对传质起关键作用的填料等组成,内有喷淋、捕雾等装置。
The desulfurization tower has packing tower, air jet tower and plate tower. The commonly used type is packed tower, which consists of a circular tower body and packings stacked in the tower, which play a key role in mass transfer. There are spraying and fog trapping devices in the tower.
在安装脱硫塔过程中需要注意哪些方面
What aspects should be paid attention to during installation of desulfurization tower
1、要求淋水填料层安装表面平整,间距均匀。
1. Require the installation surface of the Water-Sprinkled packing layer to be smooth and uniform.
2、风机应安装成向上抽风,风机叶端与塔体的间隙应均匀不大于100mm,4张叶片应调整在同一角度上,并保证叶轮旋转平面与中心线垂直。
2. Fans should be installed to draw air upwards. The clearance between the blade end and tower body of the fan should be uniformly less than 100 mm. Four blades should be adjusted at the same angle, and the rotating plane of the impeller should be perpendicular to the center line.
3、选用循环水泵,要注意其流量与冷却水量符合,使用时应保持冷却塔在设计量±5%范围内,以防水量过大,影响冷却效果。
3. When choosing circulating water pump, we should pay attention to its flow and cooling water. When using it, we should keep the cooling tower in the design range of (+5%) so as to prevent excessive water-proof and affect the cooling effect.
4、保证下立柱及下进水管与基础良好接触,基础预埋钢板,基础安装面剖平并保证在同一水面上,下立柱及下进水管轴线垂直基础面。
4. Ensure that the lower column and the lower intake pipe are in good contact with the foundation, that the foundation is embedded with steel plate, that the installation surface of the foundation is cut and that the lower column and the axis of the lower intake pipe are perpendicular to the foundation surface on the same water surface.
5、塔体分块拼装连接时,应注意使垫片圆弧面与塔体肋根圆弧面贴合,下壳体拼装应保证水密
5. When assembling and connecting the tower block by block, attention should be paid to making the gasket arc surface fit with the tower rib root arc surface, and the lower shell assembly should ensure water tightness.
6、注意保证塔体分块拼装后的直径,尤其是上塔体出风口的直径误差应尽量小。
6. Attention should be paid to ensuring that the diameter of the tower body after block assembly, especially the diameter error of the outlet of the upper tower body, should be as small as possible.
7、进出水管方向可根据现场实际情况,通过改变法兰上螺孔的方向来调节。
7. The direction of the inlet and outlet pipes can be adjusted by changing the direction of the screw holes on the flange according to the actual situation on site.
8、电源应有安全措施,电源线接好后,惦记接线盒应采取密封措施,以防潮气进入,烧坏惦记。
8. The power supply should have safety measures. After the power cord is connected, the connection box should be sealed to prevent moisture from entering and burn the connection.
