Replacement method for packing of cooling tower

Packing is the most important part of cooling tower, its efficiency is high or low, depends on the cooling water and air in the packing full contact degree.

As we all know, the surface of the packing because of the evaporation of water in the circulating water, the concentration of inorganic substances increases and crystallization precipitation, scaling on the surface of the packing and the tower, the inner wall of the pipe; Many manufacturers of packing is to rely on, adhesive and bracket of live in use in a “vicious circle”, also is the heavier weight after fouling, packing in the case of overload, add water, “bending deformation occurs, and the deformation after packing positive impact, the water impact, in turn, make the deformation is more serious, this is a kind of irreversible” vicious circle “, start the cycle, packing soon make adhesive contact with tensile fracture, collapsed, causing cooling tower cooling capacity is reduced, the main equipment heat damage, this is the reason why cooling tower packing: why do you want to change.

There are two types of placement method of cooling tower fills: hanging type and support grid type.

Two workers are installing the cooling tower fills onto the string rod.

Hanging type

1. Check and ensure the parameter of cooling tower fills, including aperture size, aperture pitch and distance from upper edge to the hole center. Incorrect parameters may cause the false installation.
2. Hang the cooling tower fill packs onto the steel tube in the cooling tower in turn.
   A working is placing the cooling tower fill blocks onto the support grid.

Support grid type

1. Bonding the cooling tower sheets into specified sizes of blocks on the construction site. When bonding, you should make sure that the pressure onto the packing sheet is even and leave the full curing time. Make sure the filler contact point are in the same water level and have same adhesive space.
2. Clean cooling tower. Clean up the dust and garbage in the internal of cooling tower.
3. Install the support grid.
4. Install the cooling tower fills. The installation of cooling tower fills should conduct as schedule and adopts partition installation method. Smooth and tidy placement as designed arrangement. For the corner and other irregular area installation, you should cut the blocks according to the actual boundary conditions. All the placement should be tidy, tight and without gaps.
5. Clean the remaining debris between the cooling tower fill blocks and on the layers to ensure all positions are clean and without any debris.
6. Install the rare layers of cooling tower fills. Until all the cooling tower fills are installed. Clean the debris after each layer of fills is installed to guarantee the best efficiency of cooling tower fills.
