Description

Technical Field

[0001] The utility model relates to the technical field of water circulation cooling towers, in particular to a water distributor for a water cooling tower with a low scaling rate. Background Art

[0002] As global water resources are becoming increasingly scarce, treating and reusing cooling water in industrial water is a very effective way to save water and reduce sewage discharge. On the one hand, it can save more than 90% of water and reduce a large amount of sewage discharge. On the other hand, it can save energy and extend the service life of heat exchange equipment. It can be seen that cooling water circulation treatment technology not only brings very significant comprehensive economic benefits to enterprises, but also can create good social benefits.

[0003] Chinese utility model patent: Publication number CN217585486U, discloses a scale-free water distribution device for a water circulation cooling tower, relates to the technical field of water circulation cooling towers, and solves the problem that the scale accumulated inside the existing water distribution device during use affects the water output. A first flow cavity is arranged at the upper end of the device shell, a support frame is arranged in the middle of the first flow cavity, a limiting plate is annularly distributed on the outside of the support frame, a scale filter is arranged inside the limiting plate, a second flow cavity is arranged at the lower end of the first flow cavity, a bearing plate is arranged on both sides of the outside of the second flow cavity, sliding blocks are arranged on both sides of the middle of the device shell, a reset spring is arranged between the bearing plate and the device shell, a drain port is arranged on one side of the bearing plate, a fixing rod is arranged on one side of the bearing plate, and a plurality of water outlets are evenly distributed laterally at the lower end of the fixing rod.

[0004] In the existing technology, when CN217585486U is in use, a bearing plate is arranged on both sides of the second flow chamber, and a fixing rod is arranged on one side of the bearing plate. After the bearing plate is pushed to move horizontally by the pressure of the water flow, the water flow can flow out through the water outlet. After the water flow disappears, the resilience of the reset spring can drive the fixing rod to reset. At the same time, the descaling block scrapes and cleans the inner wall of the device shell to clean the adhered scale to avoid affecting the water output, thereby improving the service life of the device. However, if the scale is removed by scraping, the device shell will be damaged under long-term wear, which will reduce the service life of the equipment. Therefore, a low scaling rate water cooling tower water distributor is needed to solve the above problems. Utility Model Content

[0007] The electric telescopic rod is embedded and installed on the outer side of the upper surface of the water distributor shell; wherein the bottom end of the electric telescopic rod passes through the water distributor shell and is fixedly connected to the upper surface of the water isolation pad.

[0008] When using a low scaling rate water-cooled tower water distributor in the technical solution, start the electric telescopic rod to move the water isolation pad downward and seal the drain hole. At this time, inject the acid solution into the water distributor shell through the injection tube. At this time, start the drive motor body to rotate the stirring rod in the water distributor shell, so as to ensure the uniformity of drug addition and achieve all-round descaling of the inside of the water distributor shell. After soaking in the solution, restart the electric telescopic rod to move the water isolation pad upward and open the electric control valve on the connecting pipe, so that the cooling water enters the water distributor shell and is discharged through the drain hole, thereby realizing the continued use of the water distributor body after cleaning.
