[0001] The utility model relates to a spray tower, in particular to a multi-layer spraying and high-efficiency heat-taking spray tower, belonging to the technical field of spray towers. Background Art
[0002] Spray towers, as highly efficient waste gas treatment equipment, absorb and oxidize harmful substances in waste gas by spraying liquid inside the tower, achieving waste gas purification. They offer advantages such as simple structure, ease of fabrication, ease of implementing corrosion protection measures, low pressure drop, minimal power consumption, and resistance to clogging. They are widely used in industrial waste gas treatment, sewage treatment, air humidification, fire protection, and certain industrial production processes.
[0003] Spray towers typically remove pollutants through contact between the exhaust gas and the spray liquid during waste gas treatment.

[0027] One side of the box body 21 is connected with an inlet pipe 22 and a return pipe 23. The inner wall of the box body 21 is evenly fixedly connected with a guide plate 24. The inner wall of the box body 21 is evenly fixedly connected with a heat exchange tube 25. The two ends of the heat exchange tube 25 pass through the upper surface and the lower surface of the box body 21 respectively. The outer wall of the heat exchange tube 25 is evenly fixedly connected with heat exchange fins 26. The spray liquid after heat exchange exchanges heat with the cold water inside the box body 21 when passing through the heat exchange tube 25, thereby recovering the waste heat inside the gas, reducing energy waste, and avoiding adverse effects on the environment. The cold water used for heat exchange enters from the water inlet pipe 22 and is discharged from the return pipe 23 after heat exchange. The guide plate 24 increases the travel of the cold water in the box body 21, and the heat exchange fins 26 increase the heat exchange area, thereby enhancing the heat exchange effect between the cold water and the spray liquid and improving the heat exchange efficiency of the spray tower.
[0028] In this embodiment, specifically: the main assembly 10 includes a tower body 11 and a base 12;
[0029] The bottom of the tower body 11 is fixedly connected to the base 12, and the box body 21 is fixedly connected to the inner wall of the tower body 11. One end of the water inlet pipe 22 and the return pipe 23 pass through one side of the tower body 11 and extend to the outside. Valves are installed on the water inlet pipe 22 and the return pipe 23. The water inlet pipe 22 is connected to the cold water pipeline. Cold water enters from the water inlet pipe 22 and is discharged from the return pipe 23 after heat exchange.
[0030] In this embodiment, specifically: a filter 13 is installed on one side of the tower body 11, and impurities in the spray liquid are filtered through the filter 13 to prevent the impurities from entering the liquid inlet pipe 14 and causing blockage of the pump or pipeline.
[0031] In this embodiment, specifically: the top of the filter 13 is connected to a liquid inlet pipe 14 , and a circulating pump 15 is installed on the liquid inlet pipe 14 , and the circulating pump 15 is used to circulate and transport the spray liquid.

[0033] In this embodiment, specifically: the outer wall of the liquid separation pipe 16 is evenly connected to the spray pipe 17, and the bottom of the outer wall of the spray pipe 17 is evenly installed with an atomizing nozzle 18. The spray liquid in the spray pipe 17 is atomized by the atomizing nozzle 18 to clean and purify the exhaust gas. The packing layer 110 is used to slow down and evenly distribute the exhaust gas to ensure the purification effect.

[0036] Working principle or structural principle: When in use, high-temperature exhaust gas enters the spray tower through the air inlet pipe 112, and after being decelerated and distributed by the packing layer 110, it comes into contact with the spray liquid sprayed from the atomizing nozzle 18 to complete the purification of the exhaust gas. The purified gas passes through the demisting layer 19 to remove moisture, and then is discharged from the exhaust pipe 111. The spray liquid sprays and purifies the exhaust gas while fully absorbing the waste heat of the gas, and exchanges heat with the cold water inside the box 21 when passing through the heat exchange pipe 25, thereby recovering the waste heat inside the gas, reducing energy waste, and avoiding adverse effects on the environment. The cold water used for heat exchange enters from the water inlet pipe 22 and is discharged from the return pipe 23 after heat exchange. The guide plate 24 increases the distance of the cold water in the box 21, and the heat exchange fins 26 increase the heat exchange area, thereby enhancing the heat exchange effect between the cold water and the spray liquid and improving the heat exchange efficiency of the spray tower.
