Scale and removal device of water in water

The present invention relates to an apparatus for removing scale components and foreign substances contained in water, and more particularly, to improve the structure of the apparatus for removing scale components of foreign substances, in which the scale components and foreign substances contained in water can be checked for malfunctions and failures of the apparatus. It relates to a removal device.

Recently, with the rapid development of the industry, the demand for industrial water or domestic water (hereinafter, referred to as 'water') is rapidly increasing, so the efficient use of water is becoming a major issue. On the other hand, most of the water used in the general industry is used in the cooling water system, and in this aspect, the concentrated operation of the cooling water increases the tendency of corrosion or scale existing in the water. Scale components such as ions or magnesium ions are present, which causes water quality deterioration and blockage of pipes due to corrosion of scale or scale components in the course of cooling water circulation.

Brief description of the patent application No. 10-1132645, "A foreign substance removal apparatus including a scale component", which is filed by the applicant, includes a pump for forcibly circulating water to a water supply pipe and a recovery view; First filter means for removing foreign matter having particles of 30 to 100 µm contained in the water transferred from the pump; Second filter means for removing foreign matter having 5 to 25 μm of particles contained in the water passing through the first filter means; A storage tank filled with an ion exchange resin for adsorbing scale components contained in the water passed through the second filter means; A salt tank for introducing a salt solution for regenerating the ion exchange resin of the storage tank; A control unit for selectively supplying water and salt solution into the storage tank and inducing washing and regeneration of an ion exchange resin; the control unit is installed in communication with the water supply pipe, the storage tank, and the salt tank, and the water and salt into the storage tank.

Subsequently, the salt solution in the salt tank 80 is supplied into the storage tank 60 through the first inlet pipe 62 through the second automatic valve 83 by the operation of the second pump 82. do. When a predetermined amount of salt solution is added to the storage tank 60, scale components such as calcium ions (Ca 2+) or magnesium ions (Mg 2+) adhered to the salt solution and the surface of the ion exchange resin 64 are ion exchange resins ( 64, a chemical reaction is released, and the scale component adsorbed on the ion exchange resin 64 is separated. After a predetermined time, the regeneration of the ion exchange resin 64 is completed, and the control unit opens the seventh automatic valve 66 to discharge the water and the salt solution to the outside. Subsequently, when the seventh automatic valve 66 and the second automatic valve 83 are crossed and the third automatic valve 72 is opened, water is returned to the backwashing pipe 71 and the second inlet pipe 79. Water is supplied from the bottom in the storage tank 60 to wash the ion exchange resin (64). At this time, the fourth automatic valve 73 is in a cross state, and the fifth and sixth automatic valves 70 and 68 are opened to the water washed through the fifth and sixth automatic valves 70 and 68 to the outside. Discharged.

Next, after removing the remaining salt component in the storage tank 60, the scale component can be normally collected.

Subsequently, the fourth automatic valve 73 is opened and closed, and the water passing through the ion exchange resin 64 passes through the third filter means 90 to further add foreign substances, scale components, salt components, etc. remaining in the water. Will be filtered or captured.

As described above, the scale component and the foreign substance removal device contained in the water of the present invention can individually install automatic valves and manual valves in place to recognize the operation state and the cause of failure of the device, etc. It has the advantage of quick response in the field.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
