Abstract
Description
Technical Field
[0001] The utility model relates to cooling water treatment equipment, in particular to closed cooling water treatment equipment. Background Art
[0002] During the production process, production workshops usually require cooling water for heat exchange. Traditionally, there are two methods for cooling water heat dissipation. One is to rely on cooling towers for cooling. This method is mostly used in southern regions. The cooling water system has a large cooling load, which is mainly related to production volume and is less affected by the outdoor ambient temperature. Even in winter when the outdoor ambient temperature is very low, the cooling load of the process cooling water system is still large, so chillers are required to operate and provide chilled water throughout the year. This cooling method consumes a lot of electricity and is very environmentally unfriendly. Another method for cooling water heat dissipation is to set up a water reservoir outdoors and use natural heat dissipation for cooling. This method works well in winter and is mostly used in northern regions. However, in the hot summer, due to the high water temperature, this method cannot meet the needs of heat exchange. In addition, the water reservoir occupies a large area and has high manufacturing costs. Utility Model Content
[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a closed cooling water treatment equipment, which does not require the construction of a water reservoir, consumes little electricity and has a good cooling effect.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a closed cooling water treatment equipment, including a mounting platform, on which a water tank and a cooling device are arranged, the mounting platform can drive the water tank and the cooling device to move as a whole, and the cooling device is connected to the water tank through a cooling water pipe.
[0005] Furthermore, the cooling device includes a natural cooler, and the natural cooler is arranged on the mounting platform through a mounting rack.
[0006] Furthermore, the cooling equipment also includes a chiller, and a valve is provided on the cooling water pipe, and the valve can control the water tank to be connected to the natural cooler, or to be connected to the chiller.
[0007] Furthermore, the water outlet of the natural cooler is connected to the water inlet of the chiller.
[0008] Furthermore, the water tank is divided into a high-temperature water tank and a low-temperature water tank by a partition inside the water tank, the water outlet of the high-temperature water tank is connected to the water inlet of the cooling device, and the water outlet of the cooling device is connected to the water inlet of the low-temperature water tank.
[0009] Furthermore, a gap is left between the partition and the upper side of the water tank to allow water in the high-temperature water tank and the low-temperature water tank to circulate between each other.
[0010] Furthermore, the natural cooler includes a fan body arranged above the mounting frame, a fin tube group is arranged below the fan body, a water spray pipe is arranged around the fin tube group below, and a plurality of nozzles are spaced apart on the side of the water spray pipe facing the fin tube.
[0011] Furthermore, it also includes a filter tank, which is connected to the water tank. The cooling water in the water tank can be returned to the water tank after being filtered by the filter tank.
[0012] Furthermore, it also includes a medicine barrel, which is connected to the water tank and can add bactericidal and descaling agents into the water tank.
[0013] Furthermore, a waterproof cover is provided on the top of the medicine barrel to shield it.
[0014] Furthermore, it also includes a water softener, which is connected to the water tank, the water inlet of the water softener is connected to tap water, and the water outlet of the water softener is connected to the water tank.
[0015] The beneficial effects of the utility model are:
[0016] 1) By placing the water tank and cooling equipment above the mounting platform, the mounting platform can move the entire water treatment equipment, increasing the convenience of using the water treatment equipment. Furthermore, the water tank replaces the traditional water reservoir, eliminating the need for a large reservoir and requiring only two stainless steel water tanks.
[0017] 2) When the ambient temperature is lower than the cooling water temperature, the free cooler utilizes nature's cold energy to cool the cooling water, minimizing chiller energy consumption and achieving energy savings. This is especially true in winter, when ambient temperatures are low. The free cooler utilizes nature's cold energy to provide the entire cooling capacity for the cooling water in the water tank, thus reducing equipment operating costs.
[0018] 3) Through the setting of the chiller, when the ambient temperature is higher than the cooling water temperature, the cooling water enters the chiller for cooling, which makes up for the deficiency that the natural cooler cannot cool the cooling water when the ambient temperature is high.
[0019] 4) By connecting the water outlet of the natural cooler to the water inlet of the chiller, when the ambient temperature is lower than the temperature of the cooling water before cooling but higher than the temperature of the cooling water after cooling, the cooling water flowing out of the water tank is first cooled by the natural cooler and then cooled by the chiller to a preset temperature. By first absorbing some heat through the natural cooler and then cooling it through the chiller, energy saving can be achieved.
[0020] 5) The cooling equipment is a closed-loop equipment with no evaporation, drifting and other losses, and has lower operating costs than traditional cooling water equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates an "or" relationship between the related objects.
[0029] See attached Figure 1 and attached Figure 2 As shown, an energy-saving water treatment equipment in this embodiment includes a mounting platform 1, which is a plate-shaped structure. Other structures of the water treatment equipment are arranged above the mounting platform 1. Due to the setting of the mounting platform 1, the water treatment equipment can be moved as a whole, increasing the convenience of using the water treatment equipment.
[0030] The water treatment equipment includes a water tank 2 and a cooling device 3. The cooling device 3 is a closed-loop device with no evaporation, drifting or other losses. Compared with traditional cooling water equipment, the operating cost is lower.
[0031] In some embodiments, the cooling device 3 includes a natural cooler 31. The water tank 2 is connected to the natural cooler 31 via a cooling water pipe equipped with a cooling pump. The water in the water tank 2 enters the natural cooler 31 under the action of the cooling pump and is then cooled by the natural cooler 31. When the ambient temperature is lower than the cooling water temperature, the natural cooler 31 can use the coldness of nature to cool the cooling water, minimizing the energy consumption of the chiller 32 and achieving energy conservation. Especially in winter when the ambient temperature is low, the natural cooler 31 uses the coldness of nature to provide all the cooling capacity for the cooling water in the water tank 2, thereby saving equipment operating costs.
[0032] In some embodiments, the natural cooler 31 is arranged directly above the water tank 2 and is connected to the water tank 2 through a water pipe. By arranging the natural cooler 31 above the water tank 2, the floor space of the water treatment equipment is saved and the structure of the water treatment equipment is made more compact.
[0033] In some embodiments, the free cooler 31 includes a mounting frame 312 and at least two fan bodies 311 mounted on top of the mounting frame. Finned tubes are positioned below the fan bodies 311, and a water spray pipe surrounds the finned tubes. Several nozzles are spaced apart on the side of the water spray pipe facing the finned tubes. The mounting frame 312 allows the fan bodies 311 to be suspended in the air, preventing them from directly contacting other structures. This improves the heat dissipation efficiency of the fan bodies 311.
[0034] In some embodiments, the cooling device 3 also includes a chiller 32, which is connected to the water tank 2 through a cooling water pipe. After the water in the water tank 2 enters the chiller 32 through the cooling water pipe, the water in the water tank 2 is cooled by the chiller 32 and then flows back into the water tank 2. When the ambient temperature is higher than the temperature of the cooling water before cooling, the natural cooler 31 cannot be used to cool the cooling water, and the cooling water is cooled by the chiller 32. For example, in summer, when the outdoor ambient temperature is higher than the temperature of the cooling water, the natural cooler 31 cannot be used for cooling, and the cooling water can only be cooled by the chiller 32. The chiller 32 is an air-cooled chiller 32, and can also be other types of chillers 32, as long as it can cool the cooling water.
[0035] In some embodiments, the chiller 32 is arranged on one side of the water tank 2 and is arranged in parallel with the natural cooler 31 through a cooling water pipe. Through the setting of the natural cooler 31 and the chiller 32, it is possible to choose to use the natural cooler 31 or the chiller 32 to cool the cooling water according to the temperature of the natural environment. On the one hand, energy saving is achieved, and on the other hand, the applicability of the cooling equipment can be improved.
[0036] In some embodiments, a proportional valve is provided on the cooling water pipe. One valve port of the proportional valve is connected to the water tank 2, and the other two valve ports are connected to the natural cooler 31 and the chiller 32, respectively. By adjusting the proportional valve, the cooling water flowing out of the water tank 2 can be adjusted to directly enter the natural cooler 31 or the chiller 32. At this time, the judgment is made based on the ambient temperature. When the ambient temperature is higher than the cooling water temperature, the cooling water directly enters the chiller 32 for cooling. When the ambient temperature is lower than the cooling water temperature, the cooling water first enters the natural cooler 31 for cooling.
[0037] In some embodiments, the water outlet of the natural cooler 31 is connected to the water inlet of the chiller 32. When the ambient temperature is lower than the temperature of the cooling water before cooling but higher than the temperature of the cooling water after cooling, the cooling water flowing out of the water tank 2 is first cooled by the natural cooler 31 and then cooled by the chiller 32 to a preset temperature. By first absorbing some heat through the natural cooler 31 and then cooling through the chiller 32, energy conservation can be achieved.
[0038] In some embodiments, see Appendix Figure 3As shown, the water tank 2 is a stainless steel insulated water tank 2, which has a heat preservation effect on the cooling water. The water tank 2 includes a high-temperature water tank 21 and a low-temperature water tank 22. The water tank 1 is divided into two spaces, namely the high-temperature water tank 21 and the low-temperature water tank 22, by setting a partition 23 inside the water tank 2. By setting a partition in the water tank, the water tank is divided into a high-temperature water tank 21 and a low-temperature water tank 22 without adding an additional water tank. The high-temperature water tank 21 is used to hold the cooling water before cooling and is connected to the water inlet of the natural cooling device 3. The low-temperature water tank 22 is used to hold the cooling water after cooling and is connected to the water outlet of the natural cooling device 3. By placing the cooling water before cooling and after cooling separately in the high-temperature water tank 21 and the low-temperature water tank 22, the mixing of the cooling water before cooling and after cooling is avoided, and the temperature of the cooling water after cooling can be accurately controlled.
[0039] In some embodiments, a gap 23 is left between the partition 23 and the upper side of the water tank. When the water level in one water tank is too high, it can flow from the gap 23 into the other water tank to balance the water levels of the high-temperature water tank 21 and the low-temperature water tank 22.
[0040] In some embodiments, a filter tank 6 is further included, connected to the high-temperature water tank 21. Cooling water in the high-temperature water tank 21 is filtered by the filter tank 6 and then returned to the high-temperature water tank 21. Even closed-loop water circulation systems can produce impurities and dirt. The filter tank 6 automatically filters these impurities, maintaining clean water quality. The filter tank 6 also features an automatic backwash function, reducing manual maintenance. By removing impurities from the system, heat exchange efficiency can be improved, saving energy.
[0041] In some embodiments, a reagent barrel 4 is also included, which is connected to the low-temperature water tank 22. The reagent barrel 4 is used to add biological inhibitors and metal corrosion inhibitors to the water tank 2. By adding biological inhibitors and metal corrosion inhibitors to the cooling water, and then combining it with softened water softened by the water softener 5, the problem of metal corrosion is solved and the service life of the equipment is extended.
[0042] In some embodiments, the medicine barrel 4 is arranged at one end of the mounting platform 1 close to the low-temperature water tank 22. The medicine barrel 4 is arranged at the end close to the low-temperature water tank 22. On the one hand, it is convenient to add medicine. On the other hand, it is arranged close to the low-temperature water tank 22 to save the distance of the water pipe between the medicine barrel 4 and the low-temperature water tank 22, making the water treatment equipment compact.
[0043] In some embodiments, a waterproof cover 41 is provided on the top of the medicine barrel 4 to shield it, thereby preventing dirty water from entering the medicine barrel 4 and affecting the performance of the medicine therein.
[0044] In some embodiments, a water softener 5 is also included, the water inlet of the water softener 5 is connected to tap water, and the water outlet of the water softener 5 is connected to the high-temperature water tank 21. Through the setting of the water softener 5, calcium and magnesium ions in the water are removed by ion exchange resin to reduce the water hardness.
[0045] In some embodiments, water-using equipment is also included. The cooling water of the low-temperature water tank 22 is transported to the water-using workshop through the workshop water inlet pipe 7 under the action of a water delivery pump to cool the equipment in the workshop. The cooling water is then transported to the high-temperature water tank 21 through the workshop water outlet pipe, and then the cooling water in the high-temperature water tank 21 is cooled by the cooling equipment 3. After cooling, it is transported to the low-temperature water tank 22.
[0046] In some embodiments, a control device 8 is also included. The control device 8 uses Siemens PLC intelligent control equipment and ABB frequency converter to automatically adjust the actual output power and water volume of the cooling delivery pump according to actual working conditions, which can save more than 50% of electricity costs.
[0047] The above implementation methods are only for illustrating the technical concept and features of the utility model. Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model.
