What should be paid attention to when replacing the filler of a closed cooling tower?

After a closed cooling tower has been used for a long time, there will inevitably be blockages and damage in the filling parts of the closed cooling tower. However, in order to ensure the cooling effect of the closed cooling tower, we often need to replace new cooling tower fillings. What should we pay attention to in advance when replacing the cooling tower fillings?

1. The water-sprinkling filler should be assembled according to the design and installation requirements. The design length of the forming sheet is generally divided into four specifications of 1.0, 1.25, 1.5, and 2.0 meters for selection in different engineering designs. Considering the installation and maintenance, the volume of each unit assembly block should not exceed 0.5 cubic meters.

2. When the water-sprinkling filler is assembled by bonding, it should be carried out on a flat surface. The ambient temperature on site shall not be lower than 5°C. After a group is installed, it must be pressed with a flat steel plate immediately to prevent debonding due to the warping of the forming sheet itself. After the adhesive is dried and solidified, it can be moved to a flat surface. The stacking height should not exceed 2 meters. Prevent long-term exposure.

3. According to the plane layout of the tower, small pieces of filler should be cut in a planned way to fill irregular gaps. The assembly blocks should be squeezed and filled. The filler and the tower wall, shaft, and column beam should also be squeezed and filled, and the maximum gap should not exceed 20 mm.

4. During installation, pay attention to the up and down direction of the assembly blocks. The top surface of each layer should be laid flat, and the layers should be cleaned and free of debris.

5. When installation, maintenance, and other work need to be done on the filler, a flat plate must be laid, and direct stepping is strictly prohibited.

6. During the construction, assembly, and installation process, welding work is strictly prohibited above the filler, and fire prevention measures should be taken if necessary.

7. During the installation, a dedicated person should be assigned to be responsible, strictly organized, and checked at any time to ensure the quality of the installation.
