Kühlturm

Kühlturm is a type of cooling tower used to dissipate heat from a system, such as a power plant or a process industry. The tower is a tall, freestanding structure that uses evaporation to cool the water inside it.

The Kühlturm was first introduced in the early 20th century and was widely adopted in the mid-20th century. It is still used today, particularly in older power plants and industrial facilities. The tower consists of a central column or shell, with a series of vertical or horizontal fill trays that are coated with a water-permeable material, such as wire mesh or acrylic.

Heat from the system being cooled is transferred to the water inside the tower through a network of pipes, which are typically located at the tower's base. The hot water then rises through the tower and flows over the fill trays, where it is cooled by evaporation. The cooled water then drops back down to the base of the tower, where it is recirculated.

Kühltürme can be either natural draft or forced draft, depending on the type of cooling system in use. Natural draft towers use natural air movement to drive the cooling process, while forced draft towers use fans to circulate air through the tower. Depending on size and application, Kühltürme can reach heights of tens to over a hundred meters.

In addition to their primary function of cooling, Kühltürme also help to remove pollutants and particulate matter from the air, making them a notable component of industrial plant scrubbing systems.
