Abstract:
1. A recycling cooling water filter comprising: a supersonic and electromagnetic wave limescale processor installed inside a main water recycling system of a water storage tank; a sub water recycling system installed outside the main water recycling system; the sub water recycling system comprising a water quality control unit, a limescale processor unit, a limescale separation and filter unit and a high level oxidization and processing unit; wherein cooling water in the sub water recycling system is monitored by the water quality control unit, then passes through the limescale processor unit; after the cooling water is filtered by the limescale separation and filter unit, impure water is drained out from the sub water recycling system; then a sterilization unit performs a sterilization and algae-killing process for the cooling water; the high level oxidization and processing unit processes high level oxidization and reduction at a second process of sterilization and algae-killing; pure cooling water is pumped to the water storage tank; and wherein limescale in cooling water of the main water recycling system is filtered by the supersonic and electromagnetic wave limescale processor; and thus the cooling water is pure without limescale and flows into a condenser; and where the water quality control unit further comprises: a pump for pumping cooling water in the water storage tank; a filter net for roughly filtering cooling water flow therethrough; an ORP oxidization and reduction potential meter for measuring oxidization and reduction potential difference; a PH value sensor for measuring PH value; an electric conductivity sensor for measuring conductivity; and a water quality monitor for monitoring variations of measuring data; wherein the cooling water flows through the filter net, the ORP oxidization and reduction potential meter, the PH value sensor, and the electric conductivity sensor from the isolation valve; the water quality monitor serves to monitor water quality of the ORP oxidization and reduction potential meter, the PH value sensor, and the electric conductivity sensor, wherein the limescale separation and filter unit is connected to the water quality control unit; the limescale separation and filter unit has magnetization function so that the limescales will not adhere to a tube wall and thus they can be drained out; a supersonic and electromagnetic wave limescale processor is used with the limescale separation and filter unit for removing the limescale completely; and wherein the impurities separation and filter unit is formed by an impurities separator and a bag shape filter cylinder; the impurities separator is controlled by the electric conductivity sensor of the water quality control unit; a drain section at a bottom of the impurities separator is installed with an electromotive valve; the electromotive valve is connected to the water quality monitor of the water quality control unit; by an action of the water quality monitor and the electromotive valve, dirty water is drained out from the drain tube; the sterilization unit is a copper and silver sterilizing and algae-killing unit; the sterilization unit is installed at a water outlet for sterilization and killing algae; the high level oxidization and processing unit being formed by a light oxidization tank and an ozone (H
