Water Purification System for Sterilization, Rust Removal and Corrosion Prevention

The present invention relates to a water purification system for sterilization and rust removal and corrosion prevention inside a water pipe, and more particularly, it is installed in a water storage tank, a cooling tower, or a cleaning pipe line to ion-react corrosion or scale generated by the fluid flowing in the transport pipe. It can be removed using It relates to a water purification system for sterilization and rust removal and corrosion prevention inside the water pipe.

The cooling tower is one of the important facilities of large buildings or large factories such as buildings, hotels, hospitals, department stores and theaters that we often see around us. The cooling tower is a device that cools the cooling water returned from the condenser of the refrigerator by using the evaporation heat of water while spraying the cooling water from the top. In order to reduce the consumption of cooling water, the cooling water once introduced is continuously reused, and only the amount of cooling water lost due to evaporation in the cooling process is replenished.

When water (circulating water, cooling water) is evaporated, only pure water is evaporated, and substances such as calcium and sodium are continuously accumulated, which causes corrosion and scale adhesion of cooling towers, heat exchangers, and pipes.

In addition, microorganisms, algae bacteria, etc., including Legionella bacteria that cause air-conditioning diseases, are generated in the contaminated cooling water, which may cause diseases to users due to corrosion and sludge of the cooling system caused by microorganisms.

In order to solve such a problem, a chemical treatment is performed. At this time, it is very important to inject the chemical in an accurate amount so that the appropriate chemical concentration of the cooling water is maintained at an appropriate time. Currently, on the premise of the regular discharge of cooling water, chemicals such as corrosion inhibitors are automatically added or the chemicals are added intermittently to reach the concentration calculated depending on the public or empirical knowledge.

In the case of such intermittent manual injection, considering that the chemical concentration in the cooling water is lowered according to the amount of water newly introduced due to evaporation and scattering factors in the cooling system, the chemical is injected at a high concentration, but another As the generation of chlorides and the addition time approaches, the chemical concentration decreases, causing bacteria and corrosion, and the cooling water quality management is not good due to the formation of scale.

For this reason, it is difficult to reduce costs because the amount of waste cooling water is increased, and since people inject drugs one by one, a lot of costs are incurred in managing them. Even in the case of automatic drug injection, the concentration of the drug is administered in conjunction with the water quality of the cooling water, but the size of the corresponding water purifier is required because the circulating flow of the cooling water is large, and the installation cost is high. Contaminants such as scale, corrosion, and algae cannot be removed from the cooling water. Therefore, in addition to the amount of cooling water lost due to evaporation and scattering, which is discharged regularly, new water is introduced into the cooling water to maintain the concentration of contamination at a certain level. have. In addition, when the waste cooling water is discharged, it flows into a nearby sewage treatment plant. At this time, since the waste cooling water contains a high concentration of a disinfectant, it kills microorganisms used for water treatment in the sewage treatment plant, so the water treatment efficiency is reduced.

Therefore, since it is necessary to neutralize the disinfectant component in the waste cooling water, there is a problem in that the water treatment time and cost are excessively generated. Corrosion protection device' is disclosed.

However, the 'Piping Scale Generation and Corrosion Prevention Device' of Korean Patent Application Laid-Open No. 1999-0074794 is useful for corrosion prevention, but a separate sterilization device must be provided to sterilize the cooling water. In addition, since the above devices have a structure to be installed directly on the main pipe, the problem of cost increase due to direct installation on the main pipe, the inefficiency of investment of time and money for maintenance and repair becomes a problem, and the cooling water is a clean device. There is a problem in that a driving source must exist separately by feeding back the coolant.

In consideration of the above-mentioned problems of the prior art, Korean Patent Application Laid-Open No. 2005-45573 using a copper ionized water production device with low facility cost and excellent antibacterial effect and high purification efficiency of cooling water has been previously applied and published. The above-mentioned Republic of Korea Patent Publication No. 2005-45573 has advantages in that the facility cost is low and the cooling water purification efficiency is high due to the excellent antibacterial effect. There is a problem that there is a problem that the water treatment effect according to the flow rate is unevenly generated, the problem that it is difficult to clean the scale inside the copper ionization part, the copper electrode part and the housing, and the copper ionization part is worn for a short time because the copper ionization part is made of copper material. The disadvantage is that it has a short lifespan.

According to the present invention, high-rise buildings such as factories and buildings are usually equipped with a central heating and cooling system, and the water heated in the boiler It warms or cools the room by allowing the refrigerant cooled in the cooler to pass through the heat exchanger of each floor through the connecting pipe.

Here, the cooling system of the central heating and cooling system is further provided with a cooling tower 100, which serves to cool the refrigerant that has absorbed heat while passing through the heat exchanger to some extent before it flows into the cooler. will do

Such a cooling tower 100 is usually provided with a water storage tank in the lower portion of the cylindrical body, and a supply pipe in the vertical direction is provided in the center of the body so that water passing through the heat exchanger is introduced.

In the cooling tower 100 for making cooling water, a main filter means 200 for removing foreign substances contained in the supplied fluid is connected and installed by a transfer pipe 300 . The main filter means 200 is a filtration device for removing solid foreign substances, and a type of the main filter means 200 is made of foam or metal.

The fluid filtered by the main filter means 200 is transported along the transfer pipe 300 , while fine foreign substances are removed by the sub-ion generating means 400 and a certain amount of ions are generated at the same time. The structure of the sub-ion generating means 400 has an inlet 411 and an outlet 412 as shown in the accompanying drawings, and the housing 410 having an inner space has a head member for sealing the space ( 420) That is, the lid is coupled and one end is fixed to the head member 420 while the other end is made of carbon fiber so that it has a free end. .

When an ionic reaction occurs between the busbar 640 and the busbar 640 as described above, corrosion or scale is removed by the ionic reaction between the copper and iron and the busbar 640 is gradually dissolved and a certain time elapses. The size is reduced, and at this time, the dissolution rate is higher at the lower end than at the upper end. Therefore, after a certain time has elapsed, the state of the bus bar 640 becomes thicker as it goes upward.

When the fluid containing ions is generated and flows through the transfer pipe 300 as described above, corrosion or scale generated by the fluid is removed and an ion coating layer is formed on the surface of the pipe inside, and the coating layer is corroded or scaled. prevent adhesion of

On the other hand, when a resistance is formed in the brush part 430 when the sub-ion generating means 400 is operated, heat is generated and the temperature of the fluid is instantaneously increased by 1 to 2° C., thereby activating the ions of the main ion generating device 600 at the rear stage. effect that can promote
