How to replace the cooling tower packing

Generally, the cooling tower needs to be replaced once after 5-8 years of normal use. In the absence of normal maintenance, the packing needs to be replaced once every 2 years. If the following abnormality occurs in the packing in the tower, it should be replaced in time, so that the thermal efficiency of the whole tower can reach the predetermined target.

*1. Scaling. The packing in the tower body forms scale, which is generally calcium carbonate scale attached to the packing, which is stone-like and has a relatively hard texture.

*2. Sinking. Due to the contamination of heavy mud ash, the tower body packing sometimes breeds a large number of algae organisms, which causes the packing to sink and cannot be used.

*3. Aging. After long-term use, the filler gradually becomes old, brittle and easy to break due to the erosion of water and air. The aging of high-temperature tower packing is faster than that of ordinary towers, and it is generally replaced once every 4 to 6 years.

*4. Incorrect selection or improper operation will cause serious damage to the cooling tower packing. All types of cooling towers have design work index values, and incorrect selection will directly lead to serious damage and scrapping of the cooling tower. In terms of important working indicators such as inlet water temperature and configuration tonnage, if the working index is greater than the design index value due to improper operation, it will also cause serious damage to the packing.
