[0030] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a spray heat exchange purification cooling tower, comprising a washing tower body 7 and a closed cooling tower 16, wherein the washing tower body 7 is provided with a cooling component 1, a cooling component 2, a water vapor removal component, a spray component, a cooling component 3 and an oil removal component;

[0031] Cooling assembly 1 includes a cooling fin coil 2, which is fixedly connected to the bottom wall of the washing tower body 7. One end of the cooling fin coil 2 is fixedly connected to a connecting pipe 2 11, and the other end of the cooling fin coil 2 is fixedly connected to a connecting pipe 1 19. The outside of the closed cooling tower 16 is fixedly connected to a water outlet 17 and a water inlet 18 in sequence from top to bottom. The end of connecting pipe 19 away from the cooling fin coil 2 is fixedly connected to the outside of the water outlet 17, and the end of connecting pipe 2 11 away from the cooling fin coil 2 is fixedly connected to the outside of the water inlet 18. The water outlet 17 and the water inlet 18 are used to connect to the cooling fin coil 2 in the washing tower body 7, forming a closed cooling circulation system. Cooling water is sent into the closed cooling tower 16 through connecting pipe 2 11. After cooling, it is returned to the cooling fin coil 2 in the washing tower body 7 through connecting pipe 1 19, completing the cooling cycle, thereby cooling the heated cooling oil.

[0032] Reference Figure 1 The cooling component 2 includes a heat dissipation cooling fin 2 9 and a heat dissipation cooling fin 12. The inside of the washing tower body 7 is fixedly connected with a fixed plate 2 10 and a fixed plate 13 from top to bottom. The heat dissipation cooling fin 2 9 is fixedly connected to the top of the fixed plate 2 10, and the heat dissipation cooling fin 12 is fixedly connected to the top of the fixed plate 13. The fixed plate 13 is used to carry the heat dissipation cooling fin 12. The heat dissipation cooling fin 12 is used to cool the exhaust gas for the first time. The fixed plate 2 10 is used to carry the heat dissipation cooling fin 2 9. The heat dissipation cooling fin 2 9 is used to cool the exhaust gas for the second time.

[0033] Reference Figure 2 The water vapor removal component includes a water collector 24, which is fixedly connected to the inside of the washing tower body 7. The water collector 24 is used to absorb water vapor in the purified gas.

[0034] Reference Figure 1 and Figure 2 The spray assembly includes an oil pipe 23, which is fixedly connected to the inside of the washing tower body 7. A plurality of spray heads 22 are fixedly connected to the bottom of the oil pipe 23. A cooling oil inlet 8 is provided at one end of the oil pipe 23. The outside of the cooling oil inlet 8 is fixedly connected to the oil pipe 1 5. A circulating pump 4 is provided on the outside of the washing tower body 7. The input end of the circulating pump 4 is fixedly connected to the inside of the washing tower body 7. The output end of the circulating pump 4 is fixedly connected to the end of the oil pipe 1 5 away from the cooling oil inlet 8. The cooling oil inlet 8 is used to connect to the oil pipe 1 5. Under the action of the circulating pump 4, the cooling oil inside the washing tower body 7 is transported from the oil pipe 1 5 to the oil pipe 2 23 and then to the spray head 22, thereby cooling and removing grease in the exhaust gas.

[0035] Reference Figure 1 and Figure 2The oil removal component includes a wire mesh oil remover 20, which is fixedly connected to the inside of the washing tower body 7. The wire mesh oil remover 20 is an efficient oil removal device that captures and removes grease particles in the gas through its internal wire mesh structure. It is the last oil removal process.

[0036] Reference Figure 1 - Figure 3 Cooling assembly 3 includes metal cooling fins 21, which are fixedly attached to the interior of the scrubber body 7. As gas passes through these fins, their high thermal conductivity rapidly absorbs heat from the gas, further reducing its temperature. Made from a metal material with excellent thermal conductivity, such as copper or aluminum, these fins quickly and evenly cool the gas, providing the final cooling step.

[0037] Reference Figure 1 and Figure 2 A cooling oil collection area 1 is provided at the bottom of the washing tower body 7, and a refueling pipe 14 and an oil drain pipe 15 are fixedly connected to the outside of the washing tower body 7 from top to bottom. A clean gas outlet 6 is provided at the top of the washing tower body 7, and a polluted gas inlet 3 is provided on the outside of the washing tower body 7. The cooling oil collection area 1 is used to collect cooling oil or tar and other media cooled from the gas, and then continuously circulates it to the cooling fin coil 2 through cooling water to quickly cool the heated cooling oil, and then circulates it to the upper end through a water pump for re-spraying. The polluted gas inlet 3 is used to introduce polluted gas to be treated, and the clean gas outlet 6 is used to discharge clean gas after purification. The refueling pipe 14 is located above the outside of the washing tower body 7 for adding cooling oil or tar and other media into the washing tower, and the oil drain pipe 15 is located below the outside of the washing tower body 7 for discharging the collected cooling oil or tar and other media.

[0038] Working principle: first add cooling oil, tar, conductive oil, etc. into the filling pipe 14. Driven by the circulating pump 4, the cooling oil injected into the bottom of the washing tower body 7 will be sent to the oil pipe 2 23 through the oil pipe 1 5, and finally the cooling oil will be sprayed out from the spray head 22. Industrial waste gas, polluted gas, coal gas, etc. enter from the polluted gas inlet 3, first pass through the heat dissipation cooling fin 12 for primary cooling, and then enter the upper heat dissipation cooling fin 2 9 for secondary cooling. The cooling oil, tar, conductive oil, etc. sprayed by the spray device on the upper end of the heat dissipation cooling fin 2 9 cools and removes the grease in the gas, and finally enters the upper metal cooling fin 21, the water collector 24 and the wire mesh degreaser 20 for final cooling, dehumidification and degreasing, and finally the clean gas is discharged into the air. The cooling oil that has been sprayed will first fall on the cooling fin at the bottom of the washing tower body 7. The unsoaked surface of the fin coil 2 is cooled for the first time and finally collected at the bottom of the washing tower body 7. Since the cooling oil becomes hot after spraying, a cooling fin coil 2 is provided in the cooling oil collection area 1 at the bottom. The cooling water flowing out of the closed cooling tower 16 circulates in the cooling fin coil 2. The cooling water is continuously circulated to the cooling fin coil 2 to quickly cool the heated cooling oil. The oil is then circulated to the upper end through the circulating pump 4 for spraying again. When the cooling oil in the washing tower body 7 needs to be replaced, the oil drain pipe 15 on its outside can be opened.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
