[0002] Cooling towers are required for water-cooled air conditioning systems. The cooling tower is equipped with spray pipes, packing layers and water collection trays. After the spray pipe sprays water onto the packing layer, the spray water flows downward in the packing layer and collects in the water collection tray at the bottom, and then is pumped back to the spray pipe for recycling. Since the circulating water is exposed to the air, it will absorb a large amount of dust and impurities, which will condense into flocs, easily clogging the pipes and breeding microorganisms to corrupt the water quality. In addition, if the flocs accumulate in the packing layer, they will block the pores of the packing and affect the evaporative cooling effect. The workload of cleaning the packing layer is very large, so it is necessary to change the water regularly to keep the circulating water clean. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0028] The principle of the present utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0029] Reference Figure 1-6 The utility model proposes a circulating water purification device, including a clean water tank 1, which is annular and installed on the periphery of a water collecting tray 2 of a cooling tower. The clean water tank 1 is sequentially divided into a mixing tank 11, a filtering tank 12, a sedimentation tank 13 and a clean water storage tank 14 along the extension direction. The mixing tank 11 is connected to the water collecting tray 2 through a water diversion tank 3, and the clean water storage tank 14 is connected to the spray pipe of the cooling tower through a drainage pipe 4; the circulating water purification device also includes an ozone generator 5, which is connected to the mixing tank 11 through an ozone water delivery pipe 51; a ceramic tile 6 for filtering is arranged in the filtering tank 12.

[0030] The circulating water purification device is installed around the water collecting tray 2, and can be installed in the space between the water collecting tray 2 and the cooling tower shell. If the space is narrow, the circulating water purification device can also be installed around the cooling tower shell. The clean water tank 1 is fully enclosed, and an openable top cover 7 is provided on the top. The circulating water purification device can be installed during the construction of the cooling tower, and is also suitable for later installation and modification of old cooling towers. The width of the tank can be increased or decreased according to the on-site conditions.

[0031] In this embodiment, the water collecting tray 2 and the clean water tank 1 are both annular, and the clean water tank 1 is close to the surrounding edge of the water collecting tray 2. The clean water tank 1 is symmetrically provided with two trough bodies along the clockwise and counterclockwise directions, each of which includes a mixing tank 11, a filtering tank 12 and a sedimentation tank 13. The end of the water diversion tank 3 is provided with a first branch pipe and a second branch pipe, which are respectively connected to a mixing tank 11, and the water in the two sedimentation tanks 13 is collected in the clean water storage tank 14 after being purified, and finally pumped to the spray pipe through the drain pipe 4 for spraying.

[0032] In this embodiment, the water inlet at the front end of the water diversion trough 3 is opened at the bottom of the water collecting tray 2, and the water diversion trough 3 is also provided with a drawer-type filter box 31, and the filter box 31 is located directly below the water inlet 35 of the water diversion trough. The filter box 31 is used to filter larger impurities in the circulating water. The filter box 31 is provided with a primary filter screen 32, a secondary filter screen 33 and a tertiary filter screen 34 with meshes that are gradually reduced and obliquely arranged along the water flow direction. The multi-stage filter screen can prevent impurities from accumulating on a certain level of the filter screen and causing blockage. A handle is provided on one side of the filter box 31, and impurities can be extracted and poured for cleaning. After the circulating water enters the filter box 31, it falls vertically under the action of gravity. Since the primary filter screen 32, the secondary filter screen 33 and the tertiary filter screen 34 are obliquely arranged, the contact area between the filter screen and the water will be increased, and the water that cannot pass through the filter screen in time will flow along the filter screen, increasing the filtering function of the filter screen.

[0033] After the circulating water passes through the water diversion tank 3, it first enters the mixing tank 11 to mix with the electrolytic ozone water, then passes through the filter tank 12 and the sedimentation tank 13, and then enters the clean water storage tank 14. The circulating water purification device uses electrolytic ozone water for automatic disinfection, which not only has high disinfection efficiency, but also eliminates the trouble of regularly filling disinfectants. The mixing tank 11 and the filter tank 12 are separated by a grille 15. The circulating water in the mixing tank 11 crosses the grille 15 and enters the gap between the ceramic tiles 6 from the side of the ceramic tiles 6 for filtration. The ceramic tiles 6 are stacked sideways, and the gaps between the ceramic tiles 6 extend in the same direction as the clean water tank 1. A gauze 61 is provided in the gap. The ceramic tiles 6 themselves have gaps and are good filter materials. The gauze 61 can further absorb impurities in the water. In addition, the circulating water mixed with ozone will also disinfect the gauze 61 and the ceramic tiles 6 to prevent the large-scale growth of microorganisms. The ceramic tiles 6 can be taken out regularly, rinsed and reused repeatedly, which reduces the purification cost compared to activated carbon.

[0034] The filter tank 12 and the sedimentation tank 13 are separated by a first partition 16, and the sedimentation tank 13 and the clean water storage tank 14 are separated by a second partition 17. Water flows through the top of the first partition 16 and the second partition 17. The tops of the first partition 16 and the second partition 17 are provided with tooth edges. The circulating water flows through the gaps of the tooth edges, which has a filtering effect.

[0035] In this embodiment, a water baffle 18 is provided in the sedimentation tank 13, the water baffle 18 is half submerged in the water surface and close to the first baffle 16, and the bottom of the water baffle 18 is inclined toward the second baffle 17. After the circulating water enters the sedimentation tank 13, it will flow through the bottom of the water baffle 18 due to the obstruction of the water baffle 18, and the floating ash floating on the water surface will be submerged in the water along with the water flow, increasing the probability of it being mixed with water and precipitated.

[0036] In this embodiment, the water purification tank 1 has an arc-shaped tank bottom, and the tank bottoms of the water mixing tank 11, the filter tank 12 and the sedimentation tank 13 are provided with sewage pipes 8. After the valve on the sewage pipe 8 is opened, the impurities deposited at the tank bottom can be discharged from the water purification tank 1.

[0037] When the two tanks are activated at the same time, the water flow speed is relatively slow, which is convenient for the precipitation of dust and impurities. When cleaning is required, one tank can be activated separately while the other tank is being cleaned.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
