Cooling tower packing has the advantages of water resistance, high temperature resistance and anti-static for the cooling tower, but it must be replaced after a certain period of time. If the cooling tower packing is used for a long time, there will be embrittlement, and the position of the packing will fall off, causing the cooling tower The reduction in the level of heat transfer affects the operating speed of the refrigeration unit. Therefore, in order to ensure the efficiency of the routine work of the cooling tower, the cooling tower packing should be replaced regularly after three years of application. The replacement of the cooling tower packing must be carried out in the basic cleaning of the abandoned cooling tower. Next, trlon, a cooling tower manufacturer, will tell you the steps and common precautions:
1. Before the construction of the project, protect other machinery and equipment on the spot, carry out the required protection and list. Pave the decoration construction material cloth on the floor waterproof layer.
2. Remove the old filler. Turn off the switch power supply of the motor, remove the bracing at the filling position of the cooling tower, and then remove the old filling material to remove the waste in the tower to achieve on-site cleaning.
Three, fill with new filler. Adhere to the cooling tower filler, and ensure the space for the filler during the curing period of the binder, ensure that the filler contact surface is on the same plane during bonding, and ensure that the filler contact surface bears a symmetrical force during the crimping process .
Fourth, clear the tower. Remove the dust and waste in the cooling tower, stack the filling materials in the cooling tower in order, prohibit trampling and extrusion, ensure that each layer of filling material is neat, and ensure that the filling material is tight and seamless with the edge and column circumference. No more than 2mm pitch. Repair the bracing at the filling position of the cooling tower.
5. The assembling blocks should be assembled according to the upper and lower positions, the top surface of each layer should be laid neatly, and the layers should be cleaned to remove dirt.
Six. When equipment, maintenance and other operations must be performed on the filling material, work must be carried out on a flat surface, and it is prohibited to trample on the filling material.
Seven. During the construction, assembly, and installation process, welding operations on the cooling tower filler are prohibited, and fire safety measures should be implemented when necessary. After the installation is completed, take out all the engineering construction tools in the cooling tower and the handover of assisting installation equipment. The construction completion plan of the project is completed, and all the cooling tower filler replacement method steps are completed.
8. After the cooling tower filler replacement, tower body maintenance and other processes are all completed, the construction tools and auxiliary equipment are brought out, and the project is successfully completed.
A. The bottom of the tower is selected for bonding and assembly according to the specific conditions on the site. The bonding of the water-sprayed filler should be firm, and clamp it with a flat surface immediately after assembling a group to avoid the glue opening due to the warping of the molded piece itself.
B. After the adhesive is dry, it can be moved and placed on a neat ground. The stacking height should not exceed 2 meters to avoid prolonged exposure.
c. When assembling the block device, the upper and lower adjacent layers are perpendicular to each other. The device operations are carried out separately, the laying is neat, the blocks are packed tightly, and the edges, column circumferences, tower circumferences and other irregular gap positions are correctly cut according to the actual boundaries. , Ensure that the laying is neat, covered tightly, and the large gap does not exceed 20 mm.
D. During the installation process, the interlayer and the layer of the filler are immediately removed, leaving no messy dirt.
E. After the filling material is installed, when you need to work on the filling material, be sure to lay down the planks and do not trample directly.
F. When the device is installed, it is specially responsible for the quality inspection and the construction acceptance record to ensure the quality of the device.
(1) The wave pattern between one side and one side must be in an oblique staggered manner, so that it has better thermal friction resistance;
(2) The rectangular parallelepiped packing material assembly unit is most suitable for the square tower, and there will be gaps on the circle of the circular cooling tower, which needs to be filled with a different amount of single-sided packing according to the gap;
(3) Once the filling material is blocked, it is not easy to remove. When the congestion is severe, it must be replaced as a whole, which will increase the cost.
