At present, the capital equipment that is used for the recirculated water cooling both at home and abroad is a cooling tower, on the direction of water and air current flow, mainly can be divided into reverse-flow and cross flow cooling tower, can be divided into square, rectangle, circle etc. on the profile, wherein circle is mainly used on counterflow cooling tower and the hyperbolic natural-draft cooling tower; It is several to be divided into tubular type water distribution, disc type (pond formula) water distribution, slot type water distribution and rotation water distributing etc. from water distribution manner; Cooling tower carries out work according to water and air contact heat-exchanging and evaporative cooling principle, its basic principle is hot water enters cooling tower top by upper hose a water-distributing device, then, hot water evenly is sprayed on the water-sprayed filler sheet by water-distributing device, hot water flows downward along the packing sheet surface, forms uniform moisture film on the concavo-convex surface of water-sprayed filler sheet, and cold air is under the effect of blower fan, be sucked from air inlet and enter in the tower, pass the space between the packing sheet, carry out heat exchange, absorb the heat in the moisture film with moisture film on the packing sheet, simultaneously, because the suction function in the tower, part water is evaporated, thereby the heat in the water is taken away, discharge outside the tower at last, be melt in the atmosphere, the hot water that is pulled away heat obtains cooling, is pooled at last in the bottom collecting-tank of cooling tower, enter the equipment that needs cooling, prepare circulation next time.In counterflow cooling tower, current and air-flow are reverse flow, to be air-flow from cooling tower bottom air inlet enter to turn to then vertically upward flows, and hot water disperses to spray downwards from the top water-distributing device, flowing through filler and air-flow carries out falling into water-collecting tray after the heat exchange, square counterflow cooling tower generally adopts low pressure tubular type water distribution mode to carry out branch water, and shower nozzle presses square or rectangular arranged is arranged, makes the water distribution of cooling tower even; Circular counterflow cooling tower generally adopts the turning spurt water device water distribution manner, the size of the water distributor quantity of water-locator during by cooling water is the 3-8 root, have many apertures on the every water distributor according to certain rules, current spray downwards by certain angle from aperture, spray is on filler, and the reaction force that the water ejection time is produced, promoting water-locator rotates with certain speed according to the direction opposite with water spray, make hot water can be sprayed on all fillers uniformly, when current big more, the angle of aperture is during more near level, the propulsive thrust that is produced is big more, and the rotary speed of water-locator is also fast more accordingly; In cross flow cooling tower, current become vertical direction to flow with air-flow, being air-flow enters from the air inlet of cooling tower both sides, along continuous straight runs passes filler, and hot water flows out from the nozzle (or aperture) of the distribution reservoir of top of tower bottom, and vertical spray uniformly is on filler, and the air-flow that flows downward with the level process carries out heat exchange, the air-flow that absorbs heat is aspirated and discharges outside the tower by blower fan, and hot water has distributed heat and cooled off and become cold water and fall into water-collecting tray;
