DEVICE FOR DISCHARGING FRESH WATER OF WATER STORAGE TANK IN DESALINATION SYSTEM WITH DIFFUSER CONNECTED TO DISCHARGE NOZZLE

摘要

PURPOSE: A fresh water discharge device of a water storage tank in a desalination system is provided to cut down the equipment cost by removing the unnecessary space of the water tank and reducing the size of the water tank. CONSTITUTION: A diffuser(16) is formed in a water storage tank(10) of a sea water desalination system, and connected to a discharge nozzle(12) of the water storage tank. A vortex blade is installed inside the diffuser to prevent vortex of discharge water. The size of the water storage tank is decreased by reducing the minimum water level of the water storage tank as the dead area to 1/3 to protect the suction pump of the pump station. The diffuser connected to the discharge nozzle is installed in the water storage tank, and the size of the water storage tank is decreased by lowering the discharge speed of water.
