Description

Technical Field

[0001] The present invention relates to the technical field of cooling circulating water treatment, and specifically to an industrial cooling circulating water treatment method. Background Art

[0002] At present, the main method adopted in the industrial circulating water system is to use the magnetic field induction applied externally to change the arrangement direction of water molecules in an orderly manner, thereby enhancing the polar characteristics of water molecules; there is also a method of using the electric field induction applied externally to change the arrangement direction of water molecules in an orderly manner. The ultimate goal is to polarize water molecules. Compared with the past method of adding scale inhibitors or bactericides, although the pollution problem is solved, the effect has also become worse. The reason is that the electromagnetic field technology has weak penetration power, and for relatively thick water scale, rust scale, etc., the above technical means cannot quickly achieve peeling and falling off.

[0003] In order to solve the above technical problems, it is necessary to make further improvements. Green and pollution-free is the core advantage of the existing technology and needs to be retained; develop a method that can not only achieve the effect of green and pollution-free, but also quickly achieve the peeling and falling off of water scale and rust scale. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 is a flowchart of Embodiment 1 of an industrial cooling circulating water treatment method proposed by the present invention; Figure 2 is a flowchart of Embodiment 2 of an industrial cooling circulating water treatment method proposed by the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0013] As Figure 1-2 shown, the present invention provides Embodiment 1: An industrial cooling circulating water treatment method, including the following steps: S1: High-temperature circulating water flows out from the water outlet of the water-using equipment unit, and the high-temperature circulating water flows into the cooling tower through the return pipe; The water flowing out from the water outlet of the water-using equipment unit is at a high temperature because the water absorbs the heat generated by the equipment. The high-temperature circulating water can flow into the cooling tower through the return pipe by the gravity of the return pipe network itself or relying on the pressure of the water flow, and the high-temperature circulating water will flow into the top of the cooling tower.

[0014] S2: After the high-temperature circulating water is cooled in the cooling tower, the cooled water flows into the water tank under the tower; The principle of the cooling tower is to rely on the naturally inhaled cold air to cool the high-temperature circulating water naturally, and the cooled water flows into the water pool under the tower by gravity; the function of the water pool under the tower is to store the cooled water, and at the same time, the suspended impurities in the cooled water can settle in the water pool under the tower; an inlet can also be provided in the water pool under the tower for water replenishment.

[0015] S3: Use a circulating water pump to introduce the cooled water into the self-cleaning filter; The height of the water pool under the tower is lower than that of the self-cleaning filter. Therefore, a circulating water pump is needed to absorb water from the water pool under the tower and introduce the water into the self-cleaning filter. A filter screen can also be set at the inlet of the circulating water pump during the introduction process to filter solid impurities, reducing the workload of the self-cleaning filter. When the circulating water pump absorbs water, since there are sediment substances at the bottom of the water pool under the tower, the water suction port will be at a certain height above the bottom of the water pool under the tower; since the circulating water pump pressurizes the cooling water to flow into the filter, a differential pressure gauge can be set before and after the self-cleaning filter. When the differential pressure of the differential pressure gauge is too large, there may be a malfunction; a bypass pipeline and valve can be set before and after the self-cleaning filter and used as a backup when the differential pressure is too large; a sewage outlet is also provided in the water pool under the tower to discharge sewage when the water pollution is too serious; a float valve is provided in the water pool under the tower to facilitate understanding the water level in the water pool under the tower and facilitating water replenishment.

[0016] S4: The self-cleaning filter filters the cooling water to obtain filtered cooling water; The substances filtered by the self-cleaning filter are solid substances such as suspended impurities and pipeline corrosion products.

[0017] S5: The filtered cooling water flows into the negative electron generator, and the negative electron generator penetrates the water scale, and the water scale will soon loosen, peel off and fall off; The negative electron generator is an SPL negative electron generator. SPL is the product model of the negative electron generator independently developed by the applicant. After the SPL negative electron generator is powered on, the SPL negative electron generator emits a large number of negative electrons into the cooling water through the electrodes. As a large number of negative electrons enter the water, the positively charged metal ions in the water react with the negative electrons to form atomic states, and the suspended flocs in the water become dispersed solid particles and precipitate, making the water quality clear. At the same time, since the potential difference between the water and the pipe wall decreases and approaches zero, the electrostatic adsorption force on the metal pipe wall is reduced, and the scale layer is difficult to form. For the already formed scale layer, due to the strong penetration ability of the negative electrons generated by the SPL negative electron generator and the weakened adsorption force, it begins to fall off. The potential difference decreases, the release of metal ions is inhibited, the oxidation reaction stops, and the corrosion of the metal pipe wall no longer occurs.

[0018] The negative electrons generated by the SPL negative electron generator produce the following electrochemical reactions: Ca+2 + 2e- → Ca Na+1 + e- → Na Mg+2 + 2e- → Mg Fe+3 + 3e- → Fe Cu+2 + 2e- → Cu Au+3 + 3e- → Au S6: The treated cooling water re-enters the water-using equipment unit. After the water temperature rises, step S1 is carried out again to realize water circulation.

[0019] There are very few impurities in the treated cooling water. Since water with a lot of impurities will affect the use of the water-using equipment unit, the treated cooling water in this embodiment can, in addition to the cooling effect, also play a role in preventing the water-using equipment unit from being damaged.

[0020] The present invention also provides an embodiment 2: S1: High-temperature circulating water flows out from the water outlet of the water-using equipment unit, and the high-temperature circulating water flows into the self-cleaning filter through the return pipe; S2: After the self-cleaning filter filters the water, filtered high-temperature circulating water is obtained; S3: The filtered high-temperature circulating water enters the negative electron generator for treatment; S4: The treated high-temperature circulating water enters the cooling tower; S5: The cooled water enters the water pool under the tower from the cooling tower; S6: Using a circulating water pump, the cooling water in the water pool under the tower is introduced into the water-using equipment unit to realize water circulation.

[0021] The beneficial effects of the present invention: The present invention does not add any chemical agents. While retaining the green and pollution-free effect, relying on the self-developed SPL negative electron generator, it has extremely strong penetration power and can quickly loosen, peel off and fall off the water scale.

[0022] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle of the present invention, and it also belongs to the protection scope of the present invention.
