Abstract:
A periodic ozone treatment system for a showering tower type water cooling system comprising:an ozone dissolving tank to prepare an ozone solution of fresh water and periodically supplying to said cooling system for sterilization, algae extermination and stink removing; a water showering cooling tower having a fan system for cooling showering water; a water collecting pan disposed under said showering tower for collecting cool water therein and a sand bath filter disposed following said water collecting pan for removing solid particles and impurities therefrom; a water pump directly connected to an outlet of said filter for circulating water around said cooling system; a main functional heat exchanger devised to receive the water delivered from said water pump through an ozone decomposition reactor which said ozone decomposition reactor is to prevent metal parts in said heat exchanger from corroding; a recycling water pipe to feed heated water after heat exchanging back to an inlet at a top of said showering tower; and a bypass pipe connecting between said recycling pipe of heated water and said sand bath filter for shifting heated recycling water into said filter to clean the sand by a reverse osmosis action during the period which the ozone treatment system is working.
