Some companies have reported that although water collection plates are installed in their cooling towers, the water collection effect is not significant; they therefore wish to replace them with foam eliminators that offer higher efficiency in removing foam and collecting water. Enterprises consider installing efficient demisting and foam-catching devices in cooling towers for the following reasons: 1. In areas of the north where water resources are scarce, water usage quotas are strict and costs are high; therefore, these enterprises seek to recover the large amount of liquid droplets and foam carried by the air currents in order to reduce water consumption. 2. There is severe water splashing around the cooling tower; on sunny summer days, the concrete surface in the surrounding area remains wet as if it were raining, and the ground never dries out. In winter, the concrete surface freezes severely, making it impossible to approach it for maintenance work. 3. The fan blades release a large number of liquid droplets in summer, causing noticeable vibration and swaying ; The fan blades freeze severely in winter, causing vibration and swaying, so regular de-icing is required. The motor consumes a lot of electricity, and the fan blades are difficult to maintain at high cost. Please share your views on the significance of installing foam eliminators in cooling towers, as well as any suggestions you have.

There is \"drifting water\" around the cooling tower; therefore, the effect of using foam eliminators is not very significant. The air inlet cannot be reduced in size, and as water falls from the packing, it escapes through the air inlet. This is a drawback of open cooling towers; a closed type could be considered.

“\"Water splashing\" mainly occurs at the air outlet, not at the air inlet. If there is obvious water dripping from the air inlet, then there must be a problem with the water collection tray, air duct, or exhaust system. It should have no inherent connection with closed or open types.
