Description
Technical Field
The utility model relates to a cooling water circulating device relates to cooling water circulating device technical field.
Background
A currently commonly used apparatus is a cooling water circulation apparatus for circulating water in a water cooling apparatus. In such an apparatus, the heat exchanger of the apparatus is cooled by the cooling water, and the cooling water thus heated is returned to the cooling tower to be cooled, and is circulated to the heat exchanger again.
In the above-described cooling water circulation device, water-insoluble calcium salts (scales) may be deposited on the inner wall of the pipe, on which algae or microorganisms continuously grow to cause clogging of the pipe or decrease cooling efficiency. Therefore, it is common practice to add chemicals, such as disinfectants and scale inhibitors, to the cooling water. As time passes, if the hardness of the cooling water increases as the water evaporates, scale deposition is easily generated.
However, in recent years, the use of chemicals has been controlled from the viewpoint of preventing environmental pollution. Therefore, there is a need to develop a method of sterilization and prevention of scaling that can replace the use of chemicals.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention provides a cooling water circulation device to overcome the above-mentioned drawbacks in the prior art.
According to the utility model discloses, a cooling water circulating device is provided. The cooling water circulation device comprises a cooling device for cooling water; a cooling water circulation path installed on the cooling device; and an electrolysis device for performing electrolysis treatment by the cooling water circulating through the cooling water circulation path. The cooling water flows in the cooling water circulation path, and causes the cooling water to flow into the cooling water circulation path. The electrolysis apparatus comprises: an electrolytic tank for storing cooling water; a pair of electrodes disposed in the electrolytic cell; and a voltage source for applying a voltage between the pair of electrodes.
According to the present invention, minerals such as calcium ions and magnesium ions contained in the cooling water are precipitated as scales on the electrodes during the electrolytic treatment. Thus, minerals can be removed from the cooling water to reduce adhesion of scale in the circulation path. Further, hypochlorous acid or the like having bactericidal activity is generated in the cooling water by the electrolysis treatment, and thus the growth of microorganisms can be prevented. Therefore, it is possible to restrict the adhesion of microorganisms and the adhesion of scale in the cooling water circulation path without using any chemical solution that imposes a great burden on the environment.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the cooling water circulation device 1 is a device for circulating cooling water 21 through a heat exchanger 2 provided in an air cooling apparatus, a refrigeration apparatus, or the like.
The cooling water circulation device 1 passes through a cooling water circulation path 16, which is formed in a ring shape as a whole, so that the heat exchanger 2 and the cooling tower 3 are connected to the two water flow pipes 4, respectively. A traveling path in which the cooling water 21 cooled in the cooling tower 3 flows to the heat exchanger 2, and a return path in which the cooling water 21 is warmed by passing through the heat exchanger 2. The cooling tower 3 cools the water by contact with air. The water flow pipe 4 on the traveling path side is provided with a circulation pump 18 so that the cooling water 21 cooled by the cooling tower 3 is pressure-fed to the heat exchanger 2. The cooling water 21 flowing through the cooling water circulation path 16 is lost due to evaporation and maintenance over time. Therefore, the cooling tower 3 is provided with a replenishment pipe 5 with a valve 20 for replenishing the cooling water 21 from the outside.
The cooling water circulation device 1 is provided with a bypass 17, and the opposite end thereof is connected to the cooling tower 3. The bypass 17 is provided with an electrolyzer 6.
The electrolysis device 6 is provided with an electrolysis tank 7 for storing cooling water 21, a first electrode 8 and a second electrode 9. These first and second electrodes 8, 9 are connected to a direct current power supply 10. The first electrode 8 and the second electrode 9 are not particularly limited as long as they are substances generally used in an electrolytic device. For example made of titanium and coated with platinum or carbon. A controller 11 is connected to the dc power supply 10 to control and monitor the voltage applied to the first and second electrodes 8, 9.
A water supply pipe 12 for supplying cooling water 21 from the cooling tower 3 and an outflow pipe 13, the cooling water 21 returned from the cooling tower 3 after the electrolytic treatment being connected to the electrolytic bath 7. The water supply pipe 12, the electrolytic bath 7 and the outflow pipe 13 constitute a bypass 17. A bypass pump 19 is provided on the water supply pipe 12 to pressure-feed cooling water 21 to the electrolytic bath 7. The outflow pipe 13 returns the cooling water 21 overflowing from the electrolytic bath 7.
A conical hopper 14 is provided at the bottom of the electrolytic cell 7. A discharge pipe 15 with a valve 20 is provided at the bottom of the conical hopper 14.
The process of subjecting the cooling water 21 to electrolytic processing in the cooling water circulation device 1 will now be described. When the circulation pump 18 is operated, the cooling water 21 cooled in the cooling tower 3 is supplied to the heat exchanger 2 through the water flow pipe 4 to perform heat exchange. The cooling water 21 heated by the heat exchange is returned to the cooling tower 3 through the water flow pipe 4, cooled in the cooling tower 3, and supplied to the heat exchanger 2. Therefore, the cooling water 21 cooled by the cooling tower 3 is circulated through the cooling water circulation path 16 to be cooled by an air cooling device, a refrigeration device, or the like connected to the heat exchanger.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
