Efficiency upgrading of cooling towers of compressor equipment through improved design of water spray nozzles

The spotlight is on the efficiency of cooling towers operated at industrial compressor plants, in particular, under conditions of high temperatures in the Navoi Region. It is found that the decreased efficiency of cooling of recycled water in cooling towers, especially, in the warm seasons, leads to the worsening of operation conditions of compressors, to the increase of compressed air temperature and to the overall reduction of the equipment capacity. The key cause of under-cooling is poor performance of water spray nozzles which generate too large droplets and water films. The review of various types of water spray nozzles using SolidWorks Flow Simulation spots the best design out of the standard types—the cascade nozzles. With a view to enhancing efficiency of mass transfer and heat exchange, a new swirl sprayer is designed, which ensures fragmentation of water into smaller droplets and larger area of contact with air. The mathematical model of sprayed water cooling is constructed, which allows determining the influence of the spray geometry parameters on the cooling temperature. The experimental results prove that the new nozzle design ensures the water temperature decrease by 3–4°C as compared with the water spray nozzles of conventional designs.
