Description

Technical Field

[0001] The invention relates to the field of circulating water treatment, and in particular to a water circulation online water quality stabilization device. Background Art

[0002] Cooling water circulation system, regardless of equipment combination, equipment material or water source, is plagued by scaling, fouling, corrosion and microbial problems. The above problems may exist simultaneously in the cooling water circulation system, and become more serious with the increase of concentration multiples. This can easily lead to:

[0003] (1) Scaling or slime formation in the heat exchanger causes an increase in temperature difference;

[0004] (2) The cooler is shut down unplanned due to corrosion, scaling, perforation or temperature rise alarm;

[0005] (3) Pump, shaft, and motor cooling systems suffer from corrosion and scaling, which results in reduced service life and unplanned downtime;

[0006] (4) Increase maintenance costs and reduce profits;

[0007] (5) The increase in the amount of sewage discharged has made it more difficult for downstream sewage treatment plants to handle the wastewater, which is very unfavorable to the current environmental protection policy.

[0008] The concentration of nutrients in the circulating water, the increase in water temperature and the long sunshine in summer create conditions for the rapid reproduction of bacteria and algae. The mucus secreted by a large number of bacteria acts like an adhesive, which can bind together the floating dust impurities and chemical precipitation in the water, forming a sticky sediment - biological sludge that adheres to the heat transfer surface of the condenser, not only causing under-scale corrosion, but also reducing the flow of circulating water, reducing the heat exchange efficiency, and often blocking the pipeline in severe cases.

[0009] Another problem caused by microbial growth is microbial corrosion. Microbial corrosion is a special type of corrosion, which is caused by the direct or indirect participation of microorganisms in the corrosion process and the metal destruction. Microbial corrosion generally does not exist alone, and often occurs simultaneously with electrochemical corrosion, and the two are difficult to separate. The microorganisms that cause corrosion are generally bacteria and fungi, but there are also algae and protozoa, etc. In most cases, it can be regarded as the harm caused by the joint action of various bacteria. The main way for microorganisms to affect corrosion is to indirectly participate in the corrosion action by changing the electrode potential and concentration cell. The methods are generally divided into the following categories:

[0010] 1. The slime formed by bacterial growth is deposited on the metal surface, destroying the protective film and forming a local battery;

[0011] 2. The consumption of oxygen and other compounds caused by bacterial metabolism forms ventilation difference cells and concentration difference cells, and depolarization occurs in local cells;

[0012] 3. Caused by the action of bacterial metabolites;

[0013] (1) Affect pH or acidity;

[0014] (2) Affecting the redox potential;

[0015] (3) Changes in the chemical state of the environment (including ammonia, nitrate, nitrite, sulfate, sulfide and other ions, which act as catalysts in the stress);

[0016] (4) Generate or consume oxygen and affect the oxygen concentration.

[0017] Microbiological corrosion is a localized corrosion, and almost always has signs of pitting, and its harm is extremely serious.

[0018] Therefore, how to better reduce the scaling probability of circulating water and the bacterial content in circulating water has become the research focus of various companies today. Summary of the invention

[0060] In order to facilitate the normal use of the product, the mesh scale collection bucket is made of waterproof conductive material, and the drainage filter is made of insulating material. After power is turned on, the mesh scale collection bucket becomes the cathode. The principle of this application is:

[0061] Under the action of high-frequency current, water undergoes electrolysis reaction at the cathode to generate OH-, see equation (1) and equation (2). - ions, breaking the balance between alkalinity and hardness in the solution near the cathode, and HCO3 in the solution - Ions converted to CO3 2- ions, see formula (3). At the same time, Ca 2+ Mg 2+ The scaling ions migrate to the cathode region under the action of electrostatic attraction and precipitate into CaCO3 and Mg(OH)2, respectively, as shown in Equation (4) and Equation (5).

[0062] O2+2 H2O+4e→4OH - (1)

[0063] 2H2O+2e→H2+2OH - (2)

[0064] OH - + HCO3- → CO3 2- + H2O (3)

[0065] Ca 2+ +CO3 2- →CaCO3↓ (4)

[0066] Mg 2++2OH - →Mg(OH)2↓ (5)

[0067] At the same time, under the action of the electric field, the crystal form of CaCO3 on the surface of the cathode plate changes from a hard calcite structure to a loose aragonite structure, which is easier to peel off and remove.

[0068] When in use, first connect the water outlet pipe on the base with the pipe of the circulating water system, then put the sleeve of the dirt collecting net barrel on the outside of the water outlet pipe, and make the clamp penetrate the clamp on the fixed plate, and finally rotate the dirt collecting net barrel so that the clamp moves along the slide groove to the clamping groove position.

[0071] The sterilization structure is composed of an inverted barrel-shaped sterilization barrel 44, a water inlet through hole penetrating the center of the upper end surface of the sterilization barrel 44, a water inlet filter 46 arranged on the water inlet through hole, a sterilization net barrel 47 arranged in the sterilization barrel 44 and the top of which is integrated with the upper inner wall of the sterilization barrel 44, a sterilization conductive sheet 45 with the upper end penetrating the water inlet filter 46 and extending out of the sterilization barrel 44 and the lower end connected to the sterilization net barrel 47, a plurality of net barrel inner baffles 48 arranged inside the sterilization net barrel 47, and a plurality of net barrel outer baffle rings 49 arranged between the sterilization net barrel 47 and the sterilization barrel 44; the sterilization conductive sheet 45 is connected to the positive pole of the power supply;

The baffle 48 and the net bucket outer baffle ring 49 are arranged at intervals, and the vertical distance between any net bucket inner baffle 48 and the net bucket outer baffle ring 49 adjacent to it is 5-8cm; a net bucket outer baffle ring 49 is arranged between the fixed baffle 410 and the net bucket inner baffle 48 adjacent to the fixed baffle 410; the sterilization fixed plate 42 is fixed to the bottom end of the outer side surface of the sterilization barrel 44, and the number of sterilization bayonet 412, sterilization chute 413 and sterilization card slot 414 is the same and the same as the sterilization clip 43; the front end of the sterilization chute 413 is connected to the sterilization bayonet 412, and the sterilization card slot 414 is arranged at the tail end of the sterilization chute 413.

[0074] In order to facilitate the normal use of the product, the sterilization net barrel is made of waterproof conductive material, and the water inlet filter is made of insulating material. After power is turned on, the sterilization net barrel becomes an anode. The principle of this application is:

[0075] Under the action of the electric field, the chloride ions in the water will be oxidized into free chlorine components such as chlorine gas, hypochlorous acid, and hypochlorite, as shown in formula (6), formula (7), and formula (8). It is generally believed that electrolytic chlorination mainly works through hypochlorous acid. Hypochlorous acid is a very small neutral molecule, and only it can diffuse to the negatively charged surface of bacteria and penetrate into the interior of the bacteria through the bacterial cell wall. When hypochlorous acid reaches the inside of the bacteria, it can oxidize and destroy the bacterial enzyme system, causing the bacteria to die. In the electrocatalytic reaction, some short-lived intermediates are generated on the electrode surface through the electrolysis of water and the oxygen dissolved in the water, namely ozone (formula (9)), hydroxyl radicals (formula (10)), hydrogen peroxide (formula (11)), and oxygen free radicals (formula (12)). These strong oxidizing substances can oxidize multiple components in microbial cells, thereby causing irreversible changes in the microorganisms and causing their death.

[0076] 2Cl - -2e→Cl2 (6)

[0077] Cl - +H2O-2e→HClO +H + (7)

[0078] Cl - +2OH- - 2e→ClO+H2O (8)

[0079] O2 + 2OH - -2e→O3+H2O (9)
