Description

Technical Field

[0001] This utility model belongs to the technical field of cooling water treatment equipment, specifically an electrochemical treatment device for circulating cooling water. Background Technology

[0002] The emergence of energy and chemical industry circular economy parks is an inevitable result of the coordinated, efficient, and sustainable development of my country's coal, coking, steel, and power industries. The circulating cooling water within these parks is used for heat exchange and cooling of industrial equipment. The circulating cooling water system is a major water consumer in industry, accounting for over 50% of the factory's water consumption. Therefore, increasing the concentration ratio of the circulating cooling water and reducing wastewater discharge is crucial for water conservation in the parks. The circulating cooling water contains high concentrations of corrosive and precipitating components, easily causing corrosion and scaling in heat exchange equipment. Developing circulating cooling water treatment technologies capable of removing hardness and chlorine, sterilizing, reducing water consumption, and increasing the concentration ratio is of profound significance for saving water resources, solving the problems of corrosion and scaling in heat exchange equipment, and promoting the stable and sustainable development of energy and chemical industry circular economy parks.

[0003] Traditional circulating cooling water treatment technologies mainly include chemical methods, biochemical treatment technologies, and membrane separation methods. Chemical methods are simple and efficient, but the high cost of using chemical agents makes them unaffordable for many enterprises. Poor microbial tolerance, poor treatment effects, and limited applicability have consistently limited the application of biochemical treatment technologies. Membrane separation methods suffer from high costs and membrane scaling issues. Traditional circulating cooling water treatment technologies are no longer suitable for today's highly intensive and interconnected energy and chemical circular economy parks. Utility Model Content

[0055] like Figure 4 , 5 As shown, the anode 1.2 and cathode 1.3 are fixed on two guide posts 1.4 on both sides respectively. The upper end of the guide post 1.4 passes through the top cover assembly 1 and is fixed by bolts. Each row of guide posts 1.4 is connected by narrow copper busbars 1.5, and multiple narrow copper busbars 1.5 are connected by wide copper busbars 1.6.

[0056] Specifically, the anode 1.2 can be connected to the power supply through the guide posts 1.4 on both sides, as well as the narrow copper busbar 1.5 and the wide copper busbar 1.6, and then the electrode reaction takes place in the water tank 2.

[0057] like Figure 7-9 As shown, a column 3.2 for fixing the scraper assembly 4 is provided in the middle of the lower box assembly 3. A lifting column 3.4 driven by a driving device is provided inside the column 3.2. The scraper assembly 4 is located in the middle of the upper end of the column 3.2 and is driven to rise and fall by the lifting column 3.4.

[0058] like Figure 10 , 11 As shown in Figures 1 and 12, the scraper assembly 4 includes:

[0059] The beam 4.2 is fixed in the middle to the lifting column 3.4 and moves up and down with the lifting column 3.4;

[0060] The outer scraper assembly 4.3 consists of two sets, symmetrically arranged at the left and right ends of the beam 4.2;

[0061] The inner scraper assembly 4.4 consists of 2n units, which are symmetrically installed on the front and rear sides of the beam 4.2.

[0062] Specifically, the beam 4.2 is driven by the lifting column 4.3.4 to perform lifting and lowering movements. During the lifting and lowering process, the outer scraper assembly 4.3 and the inner scraper assembly 4.4 respectively scrape the surfaces of multiple sets of metal oxide electrodes and metal sulfide electrodes arranged side by side. The metal oxide electrodes and metal sulfide electrodes are vertically arranged plate-like structures.

[0063] like Figure 2 , 3 As shown, the inner scraper assembly 4.4 includes:

[0064] Tool holder 4.4.1, two tool holders 4.4.1 are arranged side by side;

[0065] Two short scrapers I4.4.2 are provided and are respectively installed on two blade holders 4.4.1. The blades of the short scrapers I4.4.2 are set outward.

[0066] Specifically, in an inner scraper assembly 4.4, two short scrapers I4.4.2 are symmetrically arranged. The end of the blade holder 4.4.1 is connected and fixed to the beam 4.2, while the short scrapers I4.4.2 are mounted on the blade holder 4.4.1.

[0068] A long tool holder 4.3.1, wherein the long tool holder 4.3.1 is disposed on the outer side;

[0069] Short tool holder 4.3.2, wherein two sets of short tool holder 4.3.2 are provided, the two sets of short tool holder 4.3.2 are symmetrically arranged on the front and rear sides of the beam 4.2, and the two sets of short tool holder 4.3.2 are on the same straight line, and the two sets of short tool holder 4.3.2 are arranged inside the long tool holder 4.3.1;

[0072] Specifically, the outer scraper assembly 4.3 is the outermost scraper assembly at both ends of the beam 4.2. Since the long blade holder 4.3.1 and long scraper 4.3.4 on its outer side cannot be fixed to the beam 4.2, they are set as a long blade holder 4.3.1 and long scraper 4.3.4 on the outer side. It is an integral structure and does not need to be fixed to the beam 4.2.

[0073] Meanwhile, the two short tool holders 4.3.2 and the long tool holder 4.3.1 are connected as one unit by connecting beam II 4.3.5, and the short tool holders 4.3.2 and the long tool holder 4.3.1 are connected by upper and lower clamping plates to make them stable as a whole.

[0078] Specifically, the two tool holders 4.4.1 consist of two sets of elongated square tubes, with the cutting edges of both sets of elongated square tubes facing outwards. This allows the cutting edge 4.4.22 to extend from the cutting edge, thereby performing scraping operations on the metal oxide electrode and the metal sulfide electrode. Since the metal oxide electrode and the metal sulfide electrode are vertically arranged plate-like structures, the cutting edge 4.4.22 can treat the surface grooves of the plate-like structure during its up-and-down movement.

[0080] The long tool holder 4.3.1 and the tool holder 4.4.1 have the same structure, both being long rectangular tubes. The length of the long tool holder 4.3.1 is twice the length of the short tool holder 4.3.2 plus the width of the beam 4.2.

[0081] The short scraper II4.3.3 has the same structure and dimensions as the short scraper I4.4.2;

[0082] The long scraper 4.3.4 has the same structure as the short scraper I 4.4.2, and its length is twice the length of the blade 4.4.21 plus the width of the beam 4.2.

[0083] Specifically, the two tool holders 4.4.1 are connected as one unit by a connecting beam I4.4.3. Each of the two tool holders 4.4.1 is provided with a clamping plate 4.7 at both the top and bottom for connecting the tool holders 4.4.1 as one unit.

[0084] An annular protrusion 4.6 is provided on the lower middle side of the beam 2. The annular protrusion 4.6 is used to connect the output end of the lifting column 3.4.

Ribbing plates 2.3 are installed inside water tank 2 to strengthen its internal structure. A ring of bolt holes is provided along the upper and lower edges of water tank 2. The bolt holes along the upper edge correspond to bolt holes I1.3 on the perimeter of the top cover assembly 1. The top cover assembly 1 and water tank 2 are tightly connected together by bolts passing through them and are sealed. The bolt holes along the lower edge correspond to bolt holes II3.3 on the perimeter of the lower tank assembly 3. The lower tank assembly 3 and water tank 2 are tightly connected together by bolts passing through them and are sealed.

[0086] Electrochemical treatment of circulating cooling water effectively removes hardness, alkalinity, chloride ions, calcium carbonate nuclei, bacteria, algae, and other pollutants from the water through electrode reactions, bringing the ions in the circulating water to a state of equilibrium. Under the action of an external current, OH- is generated on the surface of the reactor's inner wall (cathode) through decomposition. - An alkaline environment is created, causing calcium carbonate and magnesium hydroxide to deposit on the inner wall of the reactor. On the anode surface, chloride ions are converted into free chlorine and hypochlorous acid, while hydroxyl radicals and ozone are generated to kill bacteria and algae.

[0087] In this application, the upper part is the water outlet, the right side of the pipe is the water outlet, and the lower part is the sewage outlet. During operation, water flows in from the bottom and out from the top, and the sewage generated by scale buildup is discharged from the sewage outlet.

[0088] The top cover assembly 1 serves to fix the anode 1.2, while the copper plate is used to connect all anodes and conduct electricity. Scale produced by the reaction will adhere to the surface of the cathode 2.1.

[0089] The scraper assembly 4 is in contact with the cathode. The scraper moves up and down through the hydraulic cylinder to scrape off the scale on the cathode surface.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
