Technical Field

[0002] With the rapid development of global industrialization, industrial production activities have become more frequent and the scale has continued to expand, which has led to a sharp increase in the amount of industrial wastewater. These industrial wastewaters are often at high temperatures, which is caused by heating and cooling operations during the production process. High-temperature industrial wastewater not only has a large amount of water, but also contains a large amount of pollutants, such as organic matter, heavy metals, acids and alkalis. If it is not treated and discharged directly, it will cause serious pollution to the environment; When treating high-temperature industrial wastewater, physical and chemical treatment and biochemical treatment are generally used. Physical and chemical treatment mainly includes coagulation and sedimentation, advanced oxidation and steam absorption cooling, while biochemical treatment mainly includes activated sludge method and biofilm method. When cooling by steam absorption, it is necessary to first recover the heat energy in the high-temperature industrial wastewater through a heat exchanger and reduce the temperature of the wastewater. After that, evaporative cooling is used to allow the cooled wastewater to come into contact with high-temperature air, thereby removing volatile pollutants contained in the wastewater. In the process of evaporative cooling, compressors and circulating pumps are generally used. The existing device for recycling high-temperature industrial wastewater into pure raw water still has the following technical problems when in use, such as: 1.

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] See also Figure 1-Figure 9 , the present invention provides the following technical solutions: Embodiment 1: In order to solve the problem that the cost of storing the recovered heat energy in the previous device for recycling high-temperature industrial wastewater into pure water raw water will increase, the following technical solution is provided, specifically, A device for recycling high-temperature industrial wastewater into pure water raw water includes a wastewater tank 1, a support leg 2, a support leg 8, a heat exchange component and a self-evaporation cooling component. The wastewater tank 1 is installed on the support leg 2, and the wastewater tank 1 is connected to the heat exchange component through a water pump 5. The heat exchange component can absorb heat energy in the high-temperature industrial wastewater.
[0019] The heat exchange assembly includes a connecting frame 3, a heat exchange tank 4, a heat exchange tube 6 and an air collecting bin 7. The heat exchange tank 4 is fixedly connected to the wastewater tank 1 through the connecting frame 3, and a heat exchange tube 6 is installed in the heat exchange tank 4. The two ends of the heat exchange tube 6 are sealed and penetrate the upper end and the lower end of the heat exchange tank 4, respectively, and the lower end of the heat exchange tank 4 is connected to the wastewater tank 1 through a water pump 5. The high-temperature industrial wastewater in the heat exchange tank 4 can be transported to the heat exchange tank 4 through the water pump 5. The lower end of the heat exchange tube 6 is connected to the air collecting bin 7, and the air collecting bin 7 is fixedly installed on the upper surface of the supporting foot 8. The part of the heat exchange tube 6 arranged in the heat exchange tank 4 is spiral, which is convenient for extending the heat exchange time of the heat exchange tube 6. It helps to more fully reduce the temperature of high-temperature industrial wastewater. The high-temperature industrial wastewater in the wastewater tank 1 flows into the lower end of the heat exchange tank 4 through the water pump 5. The high-temperature industrial wastewater flows from bottom to top in the heat exchange tank 4, thereby increasing the potential energy of the high-temperature industrial wastewater. At the same time, the outside air is spirally transported downward from the upper end of the heat exchange tube 6, which can greatly increase the time for the air to absorb the high-temperature industrial wastewater, thereby increasing the heat of the air. The air that absorbs heat will enter the air collecting bin 7 and be absorbed by the self-evaporative cooling component for evaporative cooling of industrial wastewater, so that the recovered heat energy can be directly utilized, avoiding the storage of recovered heat energy, and avoiding unnecessary cost increases due to the difficulty in storing heat energy.
[0020] Embodiment 2: In order to solve the problem that in the previous device for recycling high-temperature industrial wastewater into pure water raw water, additional connecting equipment is required when evaporating and cooling the high-temperature industrial wastewater, which is not conducive to energy conservation and emission reduction, the following technical solution is provided, specifically, the heat exchange component is also connected to the self-evaporative cooling component, and the industrial wastewater after cooling is evaporated by the self-evaporative cooling component to remove volatile pollutants contained therein, the self-evaporative cooling component is supported on the upper surface of the supporting leg 8, and the supporting leg 8 is also equipped with a water collecting tank 9 and a wastewater recovery tank 10, the lower end of the water collecting tank 9 is connected with a liquid collecting pipe 11, and the liquid collecting pipe 11 is connected to the lower end of the self-evaporative cooling component through a liquid infusion pipe 29, and the upper end of the wastewater recovery tank 10 is connected to the upper end of the self-evaporative cooling component.
[0021] The self-evaporative cooling assembly includes a liquid collecting hopper 12, a condensation plate 13, a liquid guide tube 14, an air intake pipe 15, a liquid collecting hole 16, a shaft 17, a fan blade 18, a support frame 19, a protrusion 20, a guide block 21, a telescopic hose 22, a gas collecting chamber 23, a piston rod 24, a connecting rod 25, a piston tube 26, a spring 27 and a connecting pipe 28. The liquid collecting hopper 12 is connected to the upper end of the heat exchange tank 4, and the upper end of the liquid collecting hopper 12 is provided with a condensation plate 13, and the lower end of the condensation plate 13 is connected to the wastewater recovery tank 10 through the liquid collecting hole 16. The lower surface of the liquid collecting hopper 12 is evenly distributed with liquid guide tubes 14 that are connected to the inside thereof, and the lower ends of each row of liquid guide tubes 14 are connected through a connecting pipe 28. The liquid collecting pipe 11 is connected to the liquid guide tube 14 closest to it through a liquid infusion pipe 29. The lower end of the inner side of the liquid guiding tube 14 is connected to the shaft rod 17 through the support frame 19 bearing, and the shaft rod 17 is provided with a fan blade 18, and the lower end of the shaft rod 17 is angularly distributed with a bump 20, and the lower end of the shaft rod 17 is sealed and connected to the upper end of the telescopic hose 22 on the outer side of the lower end of the shaft rod 17. The lower end of the telescopic hose 22 is sealed and connected to the upper end of the piston rod 24, and a T-shaped air collecting chamber 23 is provided inside the piston rod 24. A guide block 21 is provided at an angular angle on the upper end of the piston rod 24. The lower end of the piston rod 24 is sealed and penetrates to the bottom of the liquid guiding tube 14, and the lower end of the piston rod 24 is seamlessly slidably connected to the inner side of the upper end of the corresponding piston tube 26. The upper end of the piston tube 26 is coaxially connected to the lower end of the corresponding liquid guiding tube 14 through a connecting rod 25, and the lower end of the piston tube 26 is connected to the collecting chamber 23 through the suction pipe 15. The gas chamber 7 is connected through, and a spring 27 is arranged between the inner bottom end of the piston tube 26 and the lower end of the piston rod 24. The temperature of the industrial wastewater flowing from the liquid collecting hopper 12 into the liquid guiding tube 14 is relatively high at the beginning. After the industrial wastewater flows in the liquid guiding tube 14, the temperature of the industrial wastewater flowing in the liquid guiding tube 14 will be relatively low. When the industrial wastewater flows in the liquid guiding tube 14, the fan blade 18 drives the shaft 17 to rotate through its potential energy, and then the protrusion 20 can be rotated. After the protrusion 20 contacts the guide block 21 through the action of the guide block 21, the piston rod 24 gradually moves downward, and at the moment when the protrusion 20 is separated from the guide block 21, the piston rod 24 is reset under the action of the spring 27, and the piston rod 24 can be made to rotate through the spring 27, the protrusion 20 and the guide block 21. The one-way air inlet valve and the one-way air exhaust valve can make the hot air in the air collecting chamber 7 be continuously sucked into the air collecting chamber 23, and discharged from the through hole on the air collecting chamber 23 to the bottom of the fan blade 18. Since the fan blade 18 rotates at a high speed, bubbles will be formed when the hot air is just discharged from the through hole on the air collecting chamber 23, so that the fan blade 18 can cut the bubbles, which can greatly increase the contact area between the hot air and the industrial wastewater, and help to improve the efficiency and effect of evaporative cooling. When the hot air evaporates the industrial wastewater, the water vapor formed will carry away the volatile pollutants in the industrial wastewater. After the water vapor contacts the condensation plate 13, condensed water will be formed on the condensation plate 13 and slide to the position of the liquid collecting hole 16.Thereby, the condensed water containing volatile pollutants falls into the wastewater recovery tank 10, avoiding the environmental pollution problem caused by directly discharging the condensed water containing volatile substances. Since the above process only relies on the potential energy of industrial wastewater throughout the process, no external equipment is required, which not only avoids the increase of energy consumption, but also helps to save energy and reduce emissions. The condensation plate 13 is arranged inclined to the horizontal plane, and a J-shaped groove with closed ends is arranged at its lower end. The J-shaped groove at the lower end of the condensation plate 13 is a convex structure with a high middle and low ends, and the liquid collection hole 16 is arranged at a relatively low position in the J-shaped groove. The guide block 21 is an arc with an arc angle of no more than 60°, and the upper end of the guide block 21 is an inclined curved surface, and the number of the guide block 21 and the bump 20 is no more than three, the lower end of the bump 20 is a smooth hemispherical structure, and the guide block 21 is arranged on the movement trajectory of the bump 20, the upper end of the gas collecting cavity 23 is connected with the interior of the liquid guide tube 14 through evenly distributed through holes, and a one-way exhaust valve is arranged in the through hole, the lower end of the gas collecting cavity 23 is connected with the interior of the piston tube 26, and a one-way intake valve is arranged at the position where the piston tube 26 is connected to the suction pipe 15.
