Description

Technical Field

[0001] The invention relates to the technical field of cooling towers, and in particular to a cooling tower return water treatment system. Background Art

[0002] As we all know, a cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. The cooling is achieved by using water to exchange heat with air flow to generate steam. The steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature. The evaporative heat dissipation device ensures the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower. The cooling tower is a comprehensive product that integrates aerodynamics, thermodynamics, fluid mechanics, chemistry, biochemistry, materials science, static and dynamic structural mechanics, processing technology and other disciplines. Water quality is a function of multiple variables, and cooling is a multi-factor, multi-variable and multi-effect comprehensive process. During the long-term use of the cooling tower, bacteria will grow in the return water system of the cooling tower, so the return water system of the cooling tower needs to be treated.

[0003] The bottom water return system of the existing packed cooling tower is mostly of water storage barrel style. This cooling tower stores water in the water storage barrel and then returns the water. Although it has a simple structure and is easy to use, a large number of bacteria and moss will grow inside the water storage barrel after long-term use. The bacteria and moss adhere to the inner wall of the water storage barrel and are extremely difficult to clean. In addition, when cleaning the water storage barrel of the cooling tower water return system, the cooling tower needs to be stopped, which greatly reduces the working efficiency. Therefore, a water return treatment system for the cooling tower is proposed. The device is not only convenient for cleaning the water storage barrel of the cooling tower water return system, but also does not need to stop the cooling tower during cleaning, which greatly improves the working efficiency of the cooling tower and has high practicality.

[0029] It should be further explained that the stabilizing mechanism includes two short blocks 52, the two short blocks 52 are fixedly connected to the upper part of the cleaning rod 44, the other ends of the two short blocks 52 are slidably connected to short tubes 53, the two short blocks 52 are slidably sleeved inside the short tubes 53, the two short blocks 52 are fixedly connected to the short tubes with springs 54, and the two short tubes 53 are fixedly connected with long rods 55, so that the cleaning brush 45 can better clean the inside of the water storage barrel 9, and the bottom end of the water storage barrel 9 is connected to a sewage pipe 46, the lower part of the sewage pipe 46 extends to the bottom of the water storage rack 6 and is provided with a valve 3, so as to facilitate the cleaning of the water storage barrel 9. The interior of the water storage barrel 9 can be cleaned and the water inside the water storage barrel 9 can be stirred. As is known to all, stagnant water is more likely to breed bacteria and moss than running water. Therefore, in order to prevent the water in the water storage barrel 9 from forming stagnant water and causing the growth of bacteria and moss, a temporary water return mechanism is arranged on the upper part of the water storage barrel 9. The temporary water return mechanism includes a funnel 25. The funnel 25 is fixedly connected to the inside of the water storage rack 6 through a plurality of stabilizing rods 1. The inside of the funnel 25 is fixedly connected to a funnel 27 through a plurality of stabilizing rods 26. The funnel 27 is located below the guide pipe 4.

[0030] The motor 1 16, the motor 2 32, the water pump 49, and the electric push rod 30 in this embodiment are all conventional equipment purchased on the market and known to those skilled in the art. The models can be selected or customized according to actual needs. In this patent, we only use them and do not improve their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of their instruction manual, and they will not be described in detail here.

[0031] In summary, when the cooling tower return water treatment system cools the hot water, the hot water is sprayed out from the inside of the nozzle 14 through the water inlet pipe 10, the conversion block 11, and the dispersion pipe 12. Since the nozzle 14 is at a forty-five degree angle with the top of the filler 1, the nozzle 14 is affected by the pressure when spraying water. The pressure causes the nozzle 14 to drive the water spray pipe 13 to move, and the water spray pipe 13 drives the dispersion pipe 12 to rotate, so that the dispersion pipe 12 rotates at the bottom end of the conversion block 11, so that the hot water is evenly sprayed on the filler 1, increasing the contact area between the hot water and the air, and facilitating the rapid cooling of the hot water when the water returns. At the same time, the motor 16 is started, and the output end of the motor 16 drives the rotating rod 1 to rotate, and the rotating rod 1 drives the multiple sets of fan blades 17 to rotate. Through the rotation of the fan blades 17, the water vapor inside the barrel body 2 is easily sucked to the outside of the barrel body 2, and more air is allowed to enter from the inside of the air inlet hole, increasing the contact area between the hot water and the air. contact area, thereby generating more water vapor, which takes away most of the heat in the hot water through evaporation, thereby better cooling and dissipating the hot water in the water inlet pipe 10, and when the water vapor is about to pass through the condensation network 18, part of the water vapor is pre-cooled and liquefied into water droplets and then drips into the interior of the barrel body 2, preventing the hot water inside the water inlet pipe 10 from losing a large amount of water when the return water is cooled and evaporated. The water is cooled by the filler 1 and guided by the guide plate 3 to remain from the inside of the guide pipe 4. The water flows from the inside of the guide pipe 4 to the inside of the funnel 27. Because the water vapor will take away part of the water when the cooling tower cools the hot water, in order to ensure that the amount of water during the return water is equal to that during the inlet water, by starting the water pump 49, the water in the water tank 48 passes through the water pipe 1, the water pump 49, and the water pipe 2 50, and flows from the other end of the water pipe 2 50 into the interior of the funnel 2 27, supplying water to the interior of the water storage barrel 9, and the water supply is equal to the amount of water evaporated.

[0032] Since the valve 29 on the return pipe 4 28 at the bottom of the funnel 27 is closed, the funnel 27 flows to the funnel 1 25 after being full of water, and the water flows from the bottom of the funnel 1 25 to the inside of the water storage barrel 9. When the water inside the water storage barrel 9 is returned to the water storage barrel 9, the motor 2 32 is started, and the output end of the motor 2 32 drives the gear 1 33 to rotate, the gear 1 33 drives the gear 39 to rotate, the gear 39 drives the rotating rod 37 to rotate, and the rotating rod 37 drives the stirring blade 40 to rotate, so as to stir the water inside the water storage barrel 9, prevent the dead water inside the water storage barrel 9, and reduce the growth of bacteria and moss, etc., and then open the valve 1 21, the water inside the water storage barrel 9 enters the filter box 22 through the return pipe 19, and is filtered by the filter net 23. Impurities in the water are carefully filtered, and the filtered water flows out through the return pipe 20 for recycling. When cleaning the inside of the water storage barrel 9, open valve 29 and close valve 1 21. The water flowing out of the guide pipe 4 flows through funnel 1 25 and return pipe 4 28 to return pipe 3 24, and then flows from return pipe 3 24 to return pipe 2 20, which is convenient for temporary use of the cooled water. Then start the electric push rod 30, and the output end of the electric push rod 30 drives the protection box 31 to move upward, the protection box 31 drives the motor 2 32 to move upward, and the motor 2 32 drives the gear 1 33, the limit plate 34 and the tooth plate 35 to move upward, and the gear 1 33 moves upward to leave the gear 3 39 and mesh with the gear 2 38, and the two gears located above The toothed plate 35 leaves the gear 2 38, and the two toothed plates 35 located at the bottom are meshed with the gear 39 to limit the movement of the gear 39. Similarly, the two toothed plates 35 located at the top limit the movement of the gear 2 38. After the gear 1 33 is meshed with the gear 2 38, the motor 2 32 is started, and the output end of the motor 2 32 drives the gear 1 33 to rotate, the gear 1 33 drives the gear 2 38 to rotate, the gear 2 38 drives the rotating rod 2 36 to rotate, the rotating rod 2 36 drives the short tube 1 41 to rotate, the short tube 1 41 drives the short block 1 42 to rotate, the short block 1 42 drives the cleaning rod 44 to rotate, and the cleaning rod 44 drives the cleaning brush 45 to rotate. The inner wall of the water storage barrel 9 is scrubbed by the rotation of the cleaning brush 45, and the short block 1 42 and the short tube 1 41 are protected. The elastic force of spring 1 43 supports, and similarly, the elastic force of spring 2 54 between short block 2 52 and short tube 2 53 enables short block 2 52 to squeeze and support the upper part of cleaning rod 44, so that cleaning brush 45 can better fit the inner wall of water storage barrel 9, which is convenient for cleaning brush 45 to clean water storage barrel 9. The waste water after washing can be discharged through drain pipe 46 by opening valve 3.
