[0027] In this embodiment, the cooling circulating water to be treated enters the descaling tank 101 through the water inlet pipe 602. The electric adsorption structure converts calcium, magnesium and other ions in the cooling circulating water into precipitable hydroxides through electrochemical reactions, softens the cooling circulating water, thereby reducing the discharge of concentrated water and the amount of water replenishment, thereby achieving the purpose of water saving. The scum blocking structure blocks and cleans the scum floating in the descaling tank 101, preventing the scum from entering the subsequent treatment process through the water outlet 103 and the water outlet pipe 603. When there is too much sediment at the bottom of the descaling tank 101, the automatic sewage discharge structure discharges the sediment together with some cooling circulating water into the descaling tank 501 for precipitation. The supernatant in the descaling tank 501 is discharged through the supernatant discharge port 502 for reuse, and the treated cooling circulating water is discharged through the water outlet 103 and the water outlet pipe 603 to enter the subsequent treatment process.

[0028] In one embodiment, Figure 3-Figure 5 As shown, the electric adsorption structure includes an insulating plate 201 connected to the descaling tank 101, an anode plate 206 is connected to the insulating plate 201, a wire connecting column 202 for connecting wires is provided on the anode plate 206, the wire connecting column 202 penetrates the insulating plate 201, an aeration component is connected to the insulating plate 201, two hydraulic lifting rods 203 are symmetrically arranged on the outside of the descaling tank 101, the output end of the hydraulic lifting rod 203 is connected to the lifting plate 204, the lifting plate 204 is connected to the negative plate 205, and a scraping component is provided at a position corresponding to the negative plate 205 on the descaling tank 101. Under the action of the electric field, the charged particles in the cooling circulating water move toward the electrode with opposite electrical properties, and through electrochemical reaction , converting calcium, magnesium and other ions in the cooling circulating water into precipitable hydroxides attached to the negative plate 205, which has the effect of reducing the hardness of the cooling circulating water in the descaling tank 101, thereby reducing the discharge of concentrated water and reducing the amount of water replenishment to achieve the purpose of water saving. The scraper assembly includes a fixed plate 207 connected to the descaling tank 101, and the fixed plate 207 is a rectangular frame. Two scrapers 208 are symmetrically arranged on the fixed plate 207. The scrapers 208 are in contact with the negative plate 205. At set intervals, the hydraulic lifting rod 203 extends to drive the negative plate 205 to rise, and the negative plate 205 and the scraper 208 move relative to each other, and the scraper 208 scrapes off the scale on the surface of the negative plate 205.

[0029] In one embodiment, Figure 3-Figure 5As shown, the aeration assembly includes an air duct 209 connected to the insulating plate 201. The shape of the air duct 209 matches the anode plate 206. A plurality of aeration holes 210 are provided on the air duct 209. An air duct interface 211 is provided on the air duct 209. The air duct interface 211 penetrates the insulating plate 201. The gas passes through the air duct interface 211 and the air duct 209 and is ejected from the aeration holes 210, so that the cooling circulating water is more evenly in contact with the negative plate 205, thereby improving the adsorption efficiency of the negative plate 205 and facilitating the discharge of the gas generated by the electrochemical reaction in the descaling tank 101.

[0030] In one embodiment, Figure 3 As shown, the descaling tank 101 is in a right-angle trapezoid shape as a whole, and the bottom slope of the descaling tank 101 is greater than 30 degrees. The insoluble scale scraped off by the scraper 208 sinks to the bottom of the descaling tank 101 and is discharged from the sewage outlet 104 located at the lower end of the descaling tank 101.

[0031] In one embodiment, Figure 3 As shown, the anode plate 206 is made of titanium-based ruthenium material with a long service life, and the negative plate 205 is made of ordinary galvanized steel plate with good conductivity, low cost and strong wear resistance.

[0032] In one embodiment, Figure 3 and Figure 5 As shown, the automatic sewage discharge structure includes a laser transmitter 401 and a laser receiver 402 arranged in the descaling tank 101. The laser transmitter 401 and the laser receiver 402 are respectively arranged on two opposite surfaces in the descaling tank 101. The laser transmitter 401 is directly opposite to the laser receiver 402. An electric sewage discharge valve 403 is provided at the sewage outlet 104. The deposited scale blocks the laser emitted by the laser transmitter 401, and the laser receiver 402 cannot receive the laser signal. The laser receiver 402 cannot receive the laser signal within the set time period.

After a set time interval, the PLC closes the electric sewage discharge valve 403.

[0033] In one embodiment, Figure 3As shown, the scum blocking structure includes a guide groove 301 vertically arranged in the descaling tank 101, an arch plate 302 is slidably arranged in the guide groove 301, a buoyancy box 303 is connected to the arch plate 302, a scum cleaning basket 304 is connected to the buoyancy box 303, the bottom of the scum cleaning basket 304 is connected to the suction pipe 305, and the scum cleaning basket 304 is connected to the suction pump through the suction pipe 305. Under the action of the buoyancy box 303, the position of the arch plate 302 corresponds to the height of the cooling circulating water in the descaling tank 101, and the arch plate 302 has a blocking effect on the scum suspended on the surface of the cooling circulating water to prevent the scum from flowing into the water outlet 103. The suction pump is intermittently started according to the artificially set interval time to clean the scum near the arch plate 302 to prevent the scum from accumulating too much in the descaling tank 101 to produce adverse effects.

[0034] The above embodiment discloses a novel cooling circulating water saving device, wherein the cooling circulating water to be treated enters the descaling tank 101 through the water inlet pipe 602, and the charged particles in the cooling circulating water move toward the electrode with opposite electrical properties under the action of the electric field, and through electrochemical reaction, the calcium, magnesium ions in the cooling circulating water are converted into precipitable hydroxides attached to the negative plate 205, which has the effect of reducing the hardness of the cooling circulating water in the descaling tank 101, thereby reducing the discharge of concentrated water and the amount of water replenishment to achieve the purpose of water saving. At set intervals, the hydraulic lifting rod 203 extends to drive the negative plate 205 to rise, and the negative plate 205 and the scraper 208 move relative to each other, and the scraper 208 scrapes the scale on the surface of the negative plate 205. Under the action of the buoyancy box 303, the position of the arch plate 302 corresponds to the height of the cooling circulating water in the descaling tank 101, and the arch plate 302 moves the floating plate 302 suspended on the surface of the cooling circulating water. The slag acts as a barrier to prevent the slag from flowing into the water outlet 103. The suction pump is started intermittently according to the artificially set interval time to clean the slag near the arch plate 302 to prevent the slag from accumulating too much in the descaling tank 101 and causing adverse effects. The deposited scale blocks the laser emitted by the laser transmitter 401, and the laser receiver 402 cannot receive the laser signal. The laser receiver 402 cannot receive the laser signal within the set time period. The PLC that keeps communicating with the laser receiver 402 controls the electric drain valve 403 to open and discharge the scale deposited at the bottom of the descaling tank 101. After the set interval time, the PLC controls the electric drain valve 403 to close, and the accumulated scale is discharged into the scale settling tank 501 together with some cooling circulating water for precipitation. The supernatant in the scale settling tank 501 is discharged through the supernatant discharge port 502 for reuse, and the treated cooling circulating water is discharged through the water outlet 103 and the water outlet pipeline 603 to enter the subsequent treatment process.
