[0020] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] 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. A cooling tower for calcining furnace gas generally uses a water pump to draw cold water to spray the cooling medium to achieve the purpose of lowering the circulating water temperature. It is an important part of the industrial production process and a major factor in water resource consumption.

[0022] During use, the cooling tower cools down the calcining furnace gas, but the cooling effect of ordinary cooling towers is poor, and the heat exchange efficiency is greatly affected by the external environment, which greatly reduces the stability and reliability of the cooling tower operation and increases the operating cost of the cooling tower.

[0023] The utility model provides Figures 1 to 3 A calcining furnace gas cooling tower shown includes a cooling tower body 1, wherein a plurality of filter plates are arranged inside the cooling tower body 1, wherein a spray mechanism is arranged at the upper and lower ends of the filter plate located in the middle, and the spray mechanism is used for furnace gas cooling, and the spray mechanism sprays the upper and lower ends of the cooling tower body 1.

[0024] When in use, the multi-layer filter plates filter the calcining furnace gas, and in the process of filtering, the calcining furnace gas is dispersed, increasing the contact area between the spray mechanism and the calcining furnace gas, and then the dispersed calcining furnace gas is cooled by the spray mechanism, and the cooling effect is improved after the calcining furnace gas is dispersed.

[0025] The filter plates include a first filter plate 4 , a second filter plate 6 and a third filter plate 8 , and the first filter plate 4 , the second filter plate 6 and the third filter plate 8 are sequentially arranged up and down inside the cooling tower body 1 .

[0026] When in use, the calcining furnace gas is filtered through the first filter plate 4, the second filter plate 6 and the third filter plate 8 in sequence, and the calcining furnace gas is gradually dispersed.

[0027] The end faces of the first filter plate 4, the second filter plate 6 and the third filter plate 8 are all provided with through holes, and the diameters of the through holes decrease successively. The diameter of the through hole of the first filter plate 4 is larger than the diameter of the through hole of the second filter plate 6, and the diameter of the through hole of the second filter plate 6 is larger than the diameter of the through hole of the third filter plate 8.

[0028] When in use, the diameters of the through holes of the first filter plate 4, the second filter plate 6 and the third filter plate 8 are reduced successively, gradually dispersing the calcining furnace gas, disrupting it through the through holes, and gradually increasing the contact area between the calcining furnace gas and the liquid sprayed by the spray mechanism, thereby achieving a rapid cooling effect.

[0029] The spray mechanism is located at the upper and lower ends of the second filter plate 6 , and the spray mechanism includes two spray pipes 5 . Spray heads 7 are arranged on the outer circumferential surfaces of the two spray pipes 5 , and the spray heads 7 of the two spray pipes 5 are arranged opposite to each other.

[0030] When in use, the two spray pipes 5 repeatedly cool down the calcining furnace gas, and the spray head 7 disperses and sprays the spray liquid to cool down the calcining furnace gas to the maximum extent.

[0031] The opening of the spray head 7 of one of the spray pipes 5 is arranged close to the third filter plate 8 , and the opening of the spray head 7 of the other spray pipe 5 is arranged close to the first filter plate 4 .

[0032] When in use, the spray head 7 at the upper end of the second filter plate 6 sprays upwards and sprays onto the end surface of the third filter plate 8. The sprayed liquid is then further dispersed by the third filter plate 8 to facilitate faster and more complete fusion with the calcining furnace gas, thereby cooling the calcining furnace gas. The spray liquid sprayed downwards by the spray head 7 at the upper end of the second filter plate 6 directly contacts the calcining furnace gas, thereby cooling the calcining furnace gas. The calcining furnace gas is cooled by the spray heads 7 at different heights above and below, thereby cooling the calcining furnace gas more quickly. At the same time, the influence of the external environment on the heat exchange efficiency is avoided, thereby improving the stability of the cooling tower body 1.

[0033] The outer circumferential surfaces of the two spray pipes 5 that penetrate the cooling tower body 1 are connected with the water inlet pipe 3 .

[0034] When in use, the water inlet pipe 3 provides a source of spray liquid for the spray pipe 5 .

[0035] The top of the cooling tower body 1 is provided with an exhaust hole.

[0036] When in use, the cooled calcining furnace gas is discharged through the exhaust hole to prevent the cooled calcining furnace gas from staying inside the cooling tower body 1 and affecting the subsequent entry of the calcining furnace gas.

[0037] A drain pipe 2 is provided at the bottom end of the cooling tower body 1 . The bottom end of the cooling tower body 1 is an inclined surface, and one side of the inclined surface of the cooling tower body 1 is close to the drain pipe 2 .

[0038] When in use, the liquid sprayed by the spray head 7 is discharged through the drain pipe 2. The cooling tower body 1 is an inclined surface, and the side close to the drain pipe 2 is lower than the side away from the drain pipe 2, which is convenient for the timely discharge of the sprayed liquid.

[0039] Working principle: When the calcining furnace gas enters the cooling tower body 1, the cooling tower body 1 rises. During the rising process, the calcining furnace gas first contacts the first filter plate 4. The through holes of the first filter plate 4 disperse the calcining furnace gas. When the calcining furnace gas passes through the through holes, the through holes disperse the calcining furnace gas and disperse it into multiple gas columns. After passing through the first filter plate 4, the multiple gas columns of calcining furnace gas merge together again. During the fusion process, preliminary cooling is carried out. Then, it passes through the second filter plate 6 and merges again. Unlike the first filter plate 4, the diameter of the through holes of the second filter plate 6 is smaller than the diameter of the through holes of the first filter plate 4. The second filter plate 6 disperses the calcining furnace gas into more gas columns than the first filter plate 4. The third filter plate 8 disperses the calcining furnace gas into more gas columns than the second filter plate 6. Then, they merge together above each filter plate, and the fusion process performs preliminary cooling.

[0040] The spray head 7 at the upper end of the second filter plate 6 sprays upward and sprays onto the end surface of the third filter plate 8. The sprayed liquid is then further dispersed by the third filter plate 8 to facilitate faster and more complete fusion with the calcining furnace gas and cool the calcining furnace gas. The spray liquid sprayed downward by the spray head 7 at the upper end of the second filter plate 6 directly contacts the calcining furnace gas and cools the calcining furnace gas. The calcining furnace gas is cooled by the spray heads 7 at different heights above and below, so that the calcining furnace gas is cooled more quickly. At the same time, the influence of the external environment on the heat exchange efficiency is avoided, thereby improving the stability of the cooling tower body 1.

[0041] The spray head 7 at the upper end of the second filter plate 6 sprays upwards to the end surfaces of the third filter plate 8, and performs secondary spraying and cooling on the calcining furnace gas rising between the second filter plate 6 and the third filter plate 8 to ensure maximum cooling.

[0042] The spray head 7 cleans the filter plate to prevent dust in the calcining furnace gas from clogging the through holes and affecting subsequent use.

[0043] The ordinary cooling tower body 1 cannot clean the objects above the spray pipe 5, resulting in a shortened service life. The spray head 7 at the upper end of the second filter plate 6 sprays upward to clean the third filter plate 8 and the objects above the spray pipe 5, thereby extending the service life.

[0044] Embodiment 2

[0045] A purification mechanism is arranged outside the cooling tower body 1 to collect and filter the liquid flowing out from the bottom end of the cooling tower body 1. The filtered liquid is transported to the water inlet pipe 3 through a pressurizing mechanism for spraying by the spray head 7 for cooling.

[0046] A fan is installed inside the exhaust hole to facilitate the rapid exhaust of calcining furnace gas.

[0047] 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 substitutions for some of the technical features therein.
