Description

Technical Field

[0001] The utility model relates to the technical field of water distribution in cooling towers, in particular to a manual water distribution device for cooling towers. Background Art

[0002] At present, for the water receiving tray type cooling water tower in China, in order to make the equipment have a small floor area, its design structure is compact, which excessively restricts the cooling area and cooling effect, limits the flow rate and uniform distribution of the cooling water, and ignores the energy efficiency problem. In order to achieve the cooling effect, three cooling water towers in the refined extraction workshop of our factory are connected in series. After being connected in series, there are a total of twelve flow channels and twelve water receiving trays. For the safety layout and maintenance space of the upper platform, a single-flow water inlet main pipe is designed. A plurality of water outlets are arranged on the water inlet main pipe. The high-temperature water flows from the water outlet downwards through the flow channel to the water receiving tray, and then the high-temperature water flows from the uniformly distributed small holes in the water receiving tray to the filler, and contacts the air flowing from bottom to top, so as to realize the cooling of the high-temperature water.

[0003] Since the water inlet main pipe of the high-temperature water of this equipment is a single-way water flow pipeline, this design has no obvious defects when a single cooling tower is operating, but the defects are particularly obvious after three equipment are connected in series. There is a phenomenon that the water flow in the cooling tower at the beginning is sufficient and overflows, while the water volume in the cooling tower at the end is extremely small or even there is no water. On the one hand, the uneven water distribution reduces the cooling effect of the high-temperature water. On the other hand, since the cooling fan cannot start and stop according to the size of the water flow, it causes great electric energy loss and resource waste. Content of the Utility Model

[0019] In order to clearly illustrate the technical features of the present solution, the present solution will be described below through specific embodiments.

[0020] As Figures 1-3 shown, the present utility model includes a water inlet main pipe 1 and a plurality of water outlets 2 arranged at the bottom of the water inlet main pipe 1. The plurality of water outlets 2 are arranged along the long axis direction of the water inlet main pipe 1, and a water distribution adjusting mechanism for adjusting the water output of the water outlet 2 is installed above each water outlet 2.

[0021] An operation hole 3 is formed in the main water inlet pipe 1 above each water outlet 2. Each water distribution adjusting mechanism includes a water baffle 4 extending into the interior of the main water inlet pipe 1 through the operation hole 3 and a vertical adjusting rod fixed to the water baffle 4. The vertical adjusting rod is installed on the support plate 5 and can be adjusted in the longitudinal and transverse positions.

[0022] Both ends of the support plate 5 are respectively fixed to the outer wall of the main water inlet pipe 1 through vertical plates 6. In this embodiment, the support plate 5 is a horizontally arranged long strip structure. A long strip through hole is formed in the support plate 5. The vertical adjusting rod includes a smooth rod 7 in the lower section and a screw rod 8 in the upper section. The lower end of the smooth rod 7 is fixed to the water baffle 4. The upper end of the screw rod 8 passes through the long strip through hole of the support plate 5 and is fixed by two locking nuts 9. The two locking nuts 9 are respectively located on the screw rod 8 above and below the support plate 5. By moving the vertical adjusting rod left and right or up and down, the coverage area of the water baffle 4 on the water outlet 2 is adjusted, so as to realize the adjustment of the water output of the water outlet 2. In this embodiment, in order to facilitate the adjustment of the vertical adjusting rod, a circular ring operation part 10 is fixed to the top end of the screw rod 8.

[0023] In this embodiment, the water baffle 4 is an arc-shaped plate structure with a curvature in the front-back direction. The above structure of the water baffle 4 can facilitate the adjustment of the flow rate of the water outlet 2. When the water baffle 4 moves to the bottom of the main water inlet pipe 1, the water baffle 4 fits with the bottom of the main water inlet pipe 1.

[0024] In this embodiment, the diameter of the main water inlet pipe 1 is 273 mm, the diameter of the water outlet 2 is 159 mm, and the operation hole 3 is a square hole with a length and width of 250 mm each. Through the operation hole 3, it is convenient to observe the water volume in the main water inlet pipe 1 and adjust the water output of the water outlet 2.

[0025] During specific operation, according to the water volume of each water receiving tray, the position of the water baffle 4 above each water outlet 2 is adjusted to change the flow rate of the water outlet 2, so that the water output of each water outlet 2 is evenly distributed. By adjusting the vertical position of the vertical adjusting rod, the height of the water baffle 4 can be changed, and by adjusting the position of the vertical adjusting rod in the long strip through hole, the left and right positions of the water baffle 4 can be changed. The operation is simple and easy, and the effect is intuitive. Each water receiving tray can evenly share the due water volume, achieving the purpose of rapid cooling and remarkable cooling effect.

[0026] After the water flow is evenly distributed to each water receiving tray by using the utility model, the pressure in terms of power suddenly decreases. In actual operation, two cooling cooling towers do not need to start the motor, and the cooling effect can be achieved by using the natural cooling method. Starting the motor of another cooling cooling tower and reducing its frequency can make up for and adjust the temperature and time of production water.

[0027] Original power consumption: (Three 15kW motors, 50HZ frequency conversion, electricity cost 0.75 yuan, current 30A) 1.732 * 380 * 30 * 0.85 * 24 / 1000 * 30 * 12 * 0.75 * 3 = 326,263 yuan / year.

[0028] Revised power consumption: (One 15kW motor, 10HZ frequency conversion, electricity cost 0.75 yuan, current 6A) 1.732 * 380 * 6 * 0.85 * 24 / 1000 * 30 * 12 * 1 * 0.75 = 21,750 yuan / year.

[0029] Saved electricity cost: 326,232 - 21,750 = 304,513 yuan / year.

[0030] Through the present utility model, the water discharge flow rate of each water outlet 2 can be adjusted at any time, so that each water receiving tray can evenly share the due water volume, thereby achieving an ideal cooling effect, reducing power consumption, avoiding waste of resources, and realizing energy conservation and efficiency improvement.
