Cooling Tower Fill History

As a Cooling Tower Fill Exporter, share the information with you. Cooling tower fill is the most important part of a cooling tower. Its efficiency depends on the degree of cooling water and air in full contact with the filler. The filler has a temperature resistance of 50 ° C to 68 ° C, aging resistance, excellent performance, UV resistance, and long life. The role of Cooling Tower Fill in the cooling tower is to increase the heat dissipation, extend the cooling water residence time, increase the heat exchange area, and increase the heat exchange capacity. Spread water evenly. It's not filling the tower with something to cool down. A cooling tower is a device that cools hot fluids (including water) to a reasonable temperature. Waste heat generated during industrial production or refrigeration processes is generally conducted with cooling water. The role of the cooling tower is to exchange cooling water with waste heat in the tower and air so that the waste heat is transmitted to the air and dispersed into the atmosphere. Application scope of the cooling tower: air-conditioning cooling system, refrigeration series, electric furnace, injection molding, tanning, power generation, steam turbine, aluminum profile processing, air compressor, industrial water cooling, and other fields.

Cooling Tower Fill

classification

Cooling tower fill can be divided into S wave packing, diagonal staggered packing, step trapezoidal inclined wave packing, differential sine wave packing, point wave packing, hexagonal honeycomb packing, two-way wave packing, and oblique wave packing.

Materials used in cooling tower fillers include scaly wood, asbestos cement, cement mesh, plastic, fiberglass, ceramics, etc.

The earliest cooling towers used only wood. Because wood is easily available, from the advent of cooling towers to the 1960s, almost all the fillers in cooling towers were made of wood.

Rosewood is the most commonly used material for early cooling tower packing due to its antiseptic properties. The long-growing mahogany has a straight and strong shape, a long service life, and is easy to use, so the price is high. Later, old mahogany began to be in short supply and prices kept rising.

In the 1950s and 1960s, asbestos cement sheets were widely used as materials for cooling tower fillers. This material has good corrosion resistance. However, it is found that asbestos cement is harmful to the environment during processing and production, so the application of this material has gradually decreased, and some countries have banned it.

Around the 1970s, the advent of plastic packing was a major innovation in the development of cooling towers. Plastic fillers were first applied in the heating, ventilation and air-conditioning industries, and later in the refining and power plant industries. This filler is characterized by good corrosion resistance and can be used for a long time. Plastic film packing is a major innovation in the development history of cooling towers because it increases the contact area between water and air. Thereby has a better cooling capacity. However, under the high temperature and humidity working conditions of the cooling tower, the plastic filler will age and deform after working for about 3 years, affecting the cooling efficiency. And winter freezing will also have a greater impact on plastic fillers. Our company also has a Cooling Tower Infill on sale, welcome to consult.
