Spiral nozzle cooling tower applications

The working principle of the cooling tower heat when cooling water entrained in the column and exposed to air, due to the existence of temperature, cooling water and air direct heat, and because the surface and the vapor pressure difference between the air in the pressure under the effect of evaporation of the water heat away, so that heat transfer to the air and scattered into the atmosphere, so as to achieve the purpose of cooling, water distribution is a key part of the cooling tower, whose role is evenly distributed into the water filler on contact with water vapor interface increases, the cooling effect of the cooling tower greatly, so the cooling water is uniform Tabb cooling water temperature is critical to reduce, but also the cooling tower design and application of the first issues to be considered
Cooling tower and cloth bearing damage occurs frequently clogged plumbing failures, mainly due to the following factors, namely water vapor entering the bearing, the bearing internal oil emulsion deterioration failure, resulting in bearing damage caused by water distributor does not rotate; Second cycle cooling unclean water, there are many entrained debris, because the circulating water pipe line is not installed water filters and water distributor smaller diameter, debris easily block the cooling water at the blowhole Tabb
To prevent these failures, guaranteed fixed water power sprayer distribution effect, cloth hose nozzles installed to improve the spray area, you can use spiral nozzle, spiral nozzle specifically the following characteristics:
One, one-piece design, no internal vane
2, high efficiency, the injection speed and the injection angle of 50 degrees to 180 degrees
3, good atomization, portable sprayers conical, and have anti-clogging performance
4, the inner (outer) threaded connection for easy cleaning and maintenance
Spiral nozzle nozzle is one of many most distinctive kind of liquid through the continuous spiral smaller body tangent and after the collision, into a small droplet ejection, and in the nozzle chamber, the flow from the inlet to the outlet channel design, without any obstacle deflector blades and, at the same flow conditions, the maximum free diameter of the spiral nozzle is more than 2 times the conventional nozzle, to the greatest degree of reduction of the occurrence of congestion
Since the cooling medium is water, the cooling effect of the cooling tower, the cooling effect of the spray shape of the water in the circulating pump operating conditions in certain circumstances, the circulating water in the cooling tower and the impact pressure must, therefore, in the choice of nozzle type When important consideration
1, in order to improve the circulating water in the cooling tower of the distribution area of ​​the nozzle spray angle and spray pattern
2, according to the circulating pump flow to select the desired nozzle injection quantity, determine the number of nozzles, but if too many, not easy to install and maintain
So select the number of nozzles, in principle, be less in quantity, water should be uniform, in order to ensure the cooling water in the cooling tower distribution effect, select the spray angle of 150 degrees, the spray pattern is solid cone nozzle, in order to facilitate the installation, you can save installation costs, and to facilitate future maintenance, so to minimize the number of nozzles
