Description

Technical Field

[0001] The invention relates to the technical field of cooling tower filler replacement, and in particular to a cooling tower filler replacement device and method. Background Art

[0002] A cooling tower is an evaporative heat dissipation device that uses water as a circulating water coolant to dissipate waste heat generated in industry or refrigeration and air conditioning. When the cooling tower is working, dry cold air enters the air inlet grille on the side of the cooling tower, passes through the spray water, passes through the filler, and finally becomes humid hot air, which is then discharged into the outside atmosphere by the fan at the top of the cooling tower.

[0003] Traditionally, packing installation involves using packing adhesive to stick the packing sheets together outside the tower body, and then using lifting equipment to lift the packing into the tower body. However, cooling towers are sometimes not equipped with lifting conditions, so lifting equipment cannot be used for installation. The only way to replace the packing is to manually transport the old packing outside the tower and the new packing into the tower. This replacement method is time-consuming and labor-intensive, which not only prolongs the construction period, but also poses certain safety risks during the up and down transportation of personnel.
