[0002] The cooling water in the water cooling system will show an increase in alkalinity and hardness after use. High hardness and high alkalinity produce a strong tendency to scale. In order to further increase the water utilization rate, it is necessary to remove the hardness or alkalinity in the water, and then the cooling water in the water cooling system needs to be softened. Electrochemical softening and descaling technology is a commonly used technical means.

[0003] In the prior art, when softening and descaling cooling water, firstly, it is difficult to ensure that the flow rate of cooling water in various areas of the cathode zone is consistent when the cooling water is flowing, which leads to different scaling thicknesses in various areas of the cathode zone, affecting the adequacy of the cooling water softening treatment; secondly, when removing scale from the cathode zone, the removed scale will be mixed in the cooling water and is not easy to separate from the cooling water.

[0014] The method for descaling the oil-water cooling system of an industrial air compressor based on nano rare earths adopts the above-mentioned descaling device for the oil-water cooling system of an industrial air compressor based on nano rare earths, and comprises the following steps: when the electrochemical barrel is located at the water supply position, cooling water is introduced into the electrochemical barrel. After the introduction is completed, the electrochemical barrel is driven to rotate to the softening position, and the hydraulic cylinder is driven to rotate by the control motor, and the linkage frame rotates accordingly, driving each cathode rod to perform a revolution motion with the anode rod as the center. In this process, the cathode rod is driven to rotate by itself through the meshing effect between the first gear and the gear ring, so that the CaC generated in the cooling water is O3 and Mg (OH) 2 are evenly deposited on the surface of the cathode rod. After softening, the electrochemical barrel is driven to rotate to the drainage position. By controlling the extension of the hydraulic cylinder, the sealing disk is separated from the electrochemical barrel, and the cooling water after softening inside the electrochemical barrel can be discharged. Then the electrochemical barrel is driven to rotate to the dry descaling position. The hydraulic cylinder is controlled to drive the cathode rod to completely enter the descaling cylinder, and then the scraper is driven to contact the scale on the surface of the cathode rod. At the same time, the uniform scaling mechanism drives each cathode rod to revolve while rotating, and the scraper is used to remove the surface scale at each position of the cathode rod. During the external descaling process, the cathode rods and driven discs are driven to rotate by the uniform scaling mechanism. The scale scraped off the surface of the cathode rods and the scale dropped to the top of the driven disc are thrown out by the centrifugal force, and automatically fall and discharge after being thrown onto the inner wall of the descaling cylinder. After the dry descaling is completed, the electrochemical barrel is driven to rotate to the water supply position, and the cycle is repeated to soften and descale the cooling water in turn. After the entire system stops running, the electrochemical barrels are driven to rotate to the softening position in turn. After the cathode rod is driven to fully enter the heating cylinder through the control of the hydraulic cylinder extension, the liquid is injected into the liquid injection pipe. Cleaning liquid and descaling agent are injected into the heating cylinder, and the cathode rod is driven to revolve and rotate at the same time through the uniform scaling mechanism, so as to stir the cleaning liquid inside the heating cylinder and evenly distribute the descaling agent in the cleaning liquid. In this process, the descaling agent fully penetrates the scale on the surface of the cathode rod, so that the scale gradually falls off, and the friction between the rotation of the cathode rod and the cleaning liquid is used to shake off the scale on the surface of the cathode rod. After descaling is completed, the cleaning liquid inside the heating cylinder is discharged, and the centrifugal force generated by the rotation of the cathode rod and the driven disk is used to discharge the scale and the cleaning liquid together.

[0015] Compared with the prior art, the nano-rare earth-based industrial air compressor oil water cooling system descaling device and method provided by the present invention has the following beneficial effects: 1. During the softening process of cooling water, the cooling water inside the electrochemical barrel flows by driving the cathode rod to revolve. In order to avoid inconsistent scaling speeds on the front and rear surfaces of the cathode rod, the cathode rod is driven to rotate, so that the CaCO3 and Mg(OH)2 generated in the cooling water are evenly deposited on the surface of the cathode rod, thus avoiding the problem of large differences in scaling thickness on the cathode rod surface affecting the softening effect of cooling water; 2. The scale on the surface of the cathode rod is removed in time by driving the scraper, which avoids the problem that the deposition effect of the cathode rod on CaCO3 and Mg(OH)2 gradually decreases after long-term use. The scale removal treatment is carried out on the cathode rod after it is completely separated from the softened cooling water, which avoids the problem that the removed scale is mixed in the cooling water and is difficult to handle. In addition, during the descaling process, the uniform scale loading mechanism drives each cathode rod to revolve while rotating and the driven disk to rotate. The scale scraped off the surface of the cathode rod and the scale falling on the top of the driven disk are thrown out by the action of centrifugal force, and the scale automatically falls and is discharged after being thrown onto the inner wall of the scale removal cylinder, thereby achieving the effect of directional discharge of scale. 3. After the whole system stops running, the cathode rod is driven to completely enter the interior of the heating cylinder, and the uniform scaling mechanism drives the cathode rod to revolve and rotate at the same time, stirring the cleaning liquid inside the heating cylinder, so that the descaling agent is evenly distributed in the cleaning liquid. In this process, the descaling agent fully penetrates the scale on the surface of the cathode rod, so that the scale gradually falls off, and the friction between the rotation of the cathode rod and the cleaning liquid is used to shake off the scale on the surface of the cathode rod. After the descaling is completed, the centrifugal force generated by the rotation of the cathode rod and the driven disk is used at the same time to prevent the scale from adhering to the surface of the cathode rod and the driven disk, so that the scale and the cleaning liquid are discharged together, thereby improving the adequacy of descaling.

The disk 13 moves downward to the upper edge of the shell 26, so that the sealing disk 13 is separated from the electrochemical barrel 4, and the cooling water after softening treatment in the electrochemical barrel 4 can be discharged. In the process of discharge, the cathode rods 5 are driven to revolve and rotate at the same time through the uniform scaling mechanism. In this process, the driven disk 14 is synchronously driven to rotate, and the cooling water in the electrochemical barrel 4 is fully discharged through the action of centrifugal force, and then the electrochemical barrel 4 is driven to rotate to the dry descaling station. By controlling the extension of the hydraulic cylinder 8, the driven disk 14 and the sealing disk 13 are driven to move downward through the linkage frame 9 and the cathode rod 5 until the cathode rod 5 completely enters the descaling cylinder 25, and then the lifting ring 34 is driven to move upward by controlling the extension of the air cylinder 33, and each driving block 36 moves upward synchronously accordingly, and the driving When the block 36 moves upward, it abuts against the oblique groove 31, driving the driven block 27 to move toward the inside of the scale removal tube 25, so that the scraper 28 abuts against the scale on the surface of the cathode rod 5, and at the same time, the uniform scaling mechanism drives each cathode rod 5 to revolve and rotate at the same time, and cooperates with the scraper 28 to remove the surface scale at each position of the cathode rod 5. In addition, during the descaling process, the uniform scaling mechanism drives each cathode rod 5 to revolve and rotate at the same time. In this process, the driven disk 14 is synchronously driven to rotate, and the scale scraped off the surface of the cathode rod 5 and the scale falling on the top of the driven disk 14 are thrown out by the action of centrifugal force, and automatically fall and are discharged after being thrown onto the inner wall of the scale removal tube 25. After the dry descaling is completed, the cathode rod 5 and the sealing disk 13 are driven to move up and reset by controlling the hydraulic cylinder 8.Then drive the electrochemical barrel 4 to rotate to the water supply position, and circulate in this way to soften and descale the cooling water in turn. After the entire system stops running, drive each electrochemical barrel 4 to rotate to the softening position in turn, and control the hydraulic cylinder 8 to extend, and drive the driven disk 14 and the sealing disk 13 to move downward through the linkage frame 9 and the cathode rod 5 to enter the heating cylinder 38, that is, the wet descaling position. After the cathode rod 5 completely enters the heating cylinder 38, the cleaning liquid and the descaling agent are injected into the heating cylinder 38 through the injection pipe 39, and the cleaning liquid is heated by the heating cylinder 38, and the cathode rod 5 is driven to move to the side of the heating cylinder 38 through the uniform scaling mechanism. While rotating, the cleaning liquid inside the heating cylinder 38 is stirred, so that the descaling agent is evenly distributed in the cleaning liquid. In this process, the descaling agent fully penetrates the scale on the surface of the cathode rod 5, so that the scale gradually falls off, and the friction between the rotation of the cathode rod 5 and the cleaning liquid is used to shake off the scale on the surface of the cathode rod 5. After the descaling is completed, the cleaning liquid inside the heating cylinder 38 is discharged by controlling the second solenoid valve 41 to open. At the same time, the centrifugal force generated by the rotation of the cathode rod 5 and the driven disk 14 is used to prevent the scale from adhering to the surface of the cathode rod 5 and the driven disk 14, so that the scale is discharged together with the cleaning liquid.
