Irrigation device (irrigation) is a major structural element. cooling towers, determining its cooling capacity.
The main purpose of the sprinkler - crush flowing through it the water flow and keep for a long time, the maximum contact area with the cooling air produced by the fan installation.
The design of the sprinkler shall ensure that sufficient area of the cooling surface with optimal aerodynamic resistance. Depending on the nature of the prevailing cooling surface sprinklers can be: film, and membrane drip - drip (hybrid).
Each type of spray device may have a variety of structures (direct - flow trough offset and t. D. ) And sizes and can be made of different materials, depending on the inlet water temperature to the cooling tower. When selecting sprinkler must consider several other parameters as durability, strength and weight of the sprinkler, ease of assembly and installation, access for repairs and inspection, and the presence in the cold water of suspended solids and corrosive impurities.
