Under the present embodiment, the present invention can automatically maintain the pH value of the cooling water pipe 12 at a preferred dissolution rate through a feedback mechanism, which is advantageous for automatically and stably controlling the generation rate of scale.

The mode of use of the present invention is as follows:

Referring to the first figure, the cooling water tower circulating water system 10 mainly uses the water liquid 91 circulating in the cooling water pipe 12 for heat dissipation, and the heat dissipation process: starting the pressing device 14 → forcing the water liquid 91 from the The water tower outlet 114 is introduced into the cooling water pipe 12 → the water liquid 91 flows from the water tower outlet 114 through the pressurizing device 14 to the heat radiating portion 13 → the water liquid 91 absorbs heat in the heat radiating portion 13 to reduce the heat of the heat radiating portion 13 → water liquid 91 Flow from the heat radiating portion 13 to the water tower inlet 11 → the water liquid 91 flows from the cooling water pipe 12 through the water tower inlet 111 into the cooling water tower 11 → the water liquid 91 flows into the cooling water tower 11 by the ventilating portion 112 for heat dissipation and cooling The liquid 91 is dropped into the water storage portion 113 for being discharged to perform heat dissipation.

When the water liquid 91 flows in the cooling water pipe 12 for a certain period of time, scale is generated. (The cooling water pipe 12 will be blocked for a long time). At this time, the power supply device 21 can be activated according to actual conditions (for example, by adding an alkaline liquid every other month to remove or reduce scale). The electrolyzed water reactor 22 performs an electrolysis water reaction to make the working fluid 92 in the second zone 222 alkaline, and then activates the valve 261, and applies the alkaline working fluid 92 to the cooling water pipe 12, When the flow rate is 91, the scale dissolution rate inside the cooling water pipe 12 is increased, and the generation rate of the scale in the cooling water pipe 12 can be reduced.

The part to be specifically explained here is the evidence of the operation principle and experiment of this case:

Regarding the formation process of the electrolyzed water, as shown in the third figure, under the action of the direct current output from the power supply unit 21, a chemical reaction occurs between the two poles, and this process is called electrolysis. Electrolysis is the process of converting electrical energy into chemical energy. The chemical changes that occur during the treatment of electrolyzed water are closely related to the chemical composition, material concentration, electrode material and other factors in the water. The amount of precipitated substances on the two poles is proportional to the amount of electricity passing through.

In water treatment, different water purification conditions can be obtained by changing different electrode materials, electrode arrangement, reaction chamber structure, electrode action process and catalytic redox measures for water quality conditions with different chemical compositions.

Typical chemical reactions during electrolysis are as follows (known techniques):

Hydrogen is generated near the cathode:

2H ₂ O+2e-=H ² +2OH-

CO ₂ +OH-=HCO ₃ ^-

HCO ₃ ^- +OH-=CO ₃ ² -+H ₂ O

Ca ²⁺ calcium ions may form

Calcium hydroxide: Ca(OH) ₂ (scale)

Calcium carbonate: CaCO ₃ (scale)

Oxygen generation near the anode

4OH ^- =O ₂ +2H ₂ O+4e-

During the electrolysis water reaction process, it can be known that the main factors causing the water body hardness in the water body are calcium and magnesium ions, and calcium hydroxide (magnesium), calcium carbonate (magnesium) and calcium hydrogencarbonate (magnesium) are formed in the water. In addition, it can be known from the textbook of Water Chemistry that the aqueous solution of carbonic acid is dissociated from calcium carbonate and magnesium (so-called scale) in aqueous solution to carbonic acid, calcium and magnesium at a low pH. The state of bicarbonate ion is equivalent to the state of temporary hard hydrolysis. Therefore, acidic water is injected into the system to dissolve the scale of the water circulation equipment, and the calcium carbonate is dissociated into temporary hard water of calcium hydrogencarbonate.

The scale adsorption in this case will use small electrolysis experiments to conduct hard water electroplating experiments, analyze and evaluate the influence of electrode materials and blending operation parameters on electrolysis efficiency, and conduct actual tests on temporary and permanent hard water, measure and analyze water quality testing items, and evaluate them. Water quality improves efficiency.

The electrolyzed water in this experiment was prepared by using calcium sulfate CaSO ₄ and sodium hydrogencarbonate NaHCO ₃ as temporary hard water and temporary permanent hard water. Two kinds of water bodies were tested. The anode electrode part was made of titanium plated platinum wire, and the cathode electrode part was made of stainless steel mesh. The continuous experiment was carried out for 72 hours under the fixed electrolysis area, and the water sample was tested every 12 hours. The main measurement indexes were pH value, total dissolved solids (TDS), total water hardness, electrical conductivity, electrical resistivity, and salt. degree. The cathode mesh was taken every 24 hours, the cathode mesh was dried to remove moisture, and the weight of the scale adsorbed by the cathode mesh was measured, and the measurement was continued.

Data analysis on scale adsorption efficiency:

First, regarding the temporary hard water scale adsorption part:

According to the experimental data (as shown in Table 1), in the temporary hard water scale adsorption amount and water hardness improvement trend, it can be known that the effect of electrolytic adsorption of scale is effective to achieve a decrease in TDS after 72 hours of continuous experiment. In addition, by measuring the weight of calcium and magnesium ions adsorbed by the cathode electrode, it is positively correlated with the TDS data of the water body and the total hardness of the water body.

The eighth figure is a schematic diagram showing the trend of the total hardness of the temporary hard water scale adsorbing water body by the first curve L1.

The ninth graph is a schematic diagram showing the tendency of temporary hard water scale adsorption TDS by the second curve L2.

The tenth, tenth, and tenth Cth drawings are schematic diagrams showing that the temporary hard water scale is adsorbed to the cathode at 24 hours, 48 hours, and 72 hours, respectively, indicating that many scales have been effectively adsorbed.

Secondly, the temporary and permanent hard water scale adsorption parts (as shown in Table 2, 11th, 12th, 13th, 13th and 3rd C):

The eleventh figure is a schematic diagram showing the tendency of the temporary and permanent hard water scale to adsorb the total hardness of the water body in a third curve.

The twelfth graph is a schematic diagram showing the tendency of temporary and permanent hard water scale adsorption TDS by a fourth curve.

Figures 13A, 13B and 13C are schematic diagrams showing the temporary and permanent hard water scale adsorption to the cathode at 24 hours, 48 hours and 72 hours, respectively. They respectively show that many scales have been effectively adsorbed.

It can be seen from the above two experiments that either "temporary hard scale adsorption" or "temporary and permanent hard scale adsorption" can be applied.

In addition, since the electrolyzed water generating part of the present case can generate alkaline water and is alkaline The water supply unit supplies the alkaline water into the water of the cooling water tower. At this time, if calcium ions or magnesium ions (or similar metal ions) are present in the water, the alkaline water can be effectively combined with calcium ions or magnesium ions. Combine (ie scale).

Since the alkaline water supply portion of the present invention is provided with the first mesh electrode, the scale can be effectively adsorbed. Therefore, after a period of time, the first mesh electrode having adsorbed scale can be taken out and replaced.

In other words, the case first uses alkaline water to capture calcium ions or magnesium ions in the water to combine it into a calcium compound or a magnesium compound (ie, scale); and then use the first mesh electrode of the adjacent alkaline water supply portion. It is a consumable that is immersed in the water of the cooling tower to absorb the scale. It can effectively remove the scale as long as it is replaced regularly.

Of course, the first mesh electrode (and/or the second electrode mesh) may be flat or curled into a cylindrical shape or other shapes, and does not affect the function of the present case.

The advantages and functions of the present invention are as follows:

[1] Good segregation effect is harmless to human body and environment. Since the case uses alkaline water generated by electrolyzed water, it is edible, harmless to the human body, and does not pollute the environment. The alkaline water in the case can be introduced into the cooling water tower, and then matched with the first mesh electrode (and/or the second electrode mesh), which can effectively reduce the scale, and at the same time avoid the environmental pollution caused by the conventional administration method and the maintenance personnel for the equipment. Health also has an impact.

[2] Suitable for long-term use by institutions. Since the first mesh electrode (and/or the second electrode mesh) of the present invention is a consumable material, when there is too much scale to be adsorbed, it can be replaced as long as it is suitable for long-term use by the institution, and the application level of the industry is high.

[3] Precise control of the conditions under which alkaline water is produced. Due to the electrolysis of the case The voltage level of the part is very easy to control, so the introduction amount and pH value of the alkaline water can be precisely controlled.

[4] The time to remove scale can be set. The invention can set the valve on the alkaline water supply part to be electronic (of course, the mechanical type can also be controlled, depending on the design of the actual equipment), and the time is automatically started to remove the scale.

The present invention has been described in detail with reference to the preferred embodiments of the present invention, without departing from the spirit and scope of the invention.
