The last part of the vaporized water will be discharged from the exhaust port along with the gas and cannot be recovered. It is not enough to save water and energy. Moreover, the recovery port for recovering water at the bottom is easily clogged by impurities after long-term use, thereby affecting the recovery efficiency. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] Example 1, please refer to Figure 1-5 The utility model provides an energy-saving circulating cooling tower, comprising a cooling tower body 1, an exhaust port 101, a fan 2, a circulation box 3, a circulation duct 301, a spray ring 302, a transverse bracket 4, a pillar 401, a condensation ring 5, a connecting net 501, a condensation column 502, a filter box 6, a filter screen 601, a cover plate 602, a motor 603, a cleaning scraper 604, a connecting column 605, and a drain pipe 606. The top of the cooling tower body 1 is provided with an exhaust port 101, the inside of the exhaust port 101 is provided with a fan 2, the exhaust port 101 is provided with a spray ring 302 near the bottom of the cooling tower body 1, the side of the cooling tower body 1 is provided with a circulation box 3, and the top of the circulation box 3 is provided with a circulation duct 301, and the circulation duct 301 is connected to the spray ring 302;

[0025] Specifically, such as Figure 3 and Figure 5 As shown, a transverse bracket 4 is provided between the spray rings 302. The transverse bracket 4 is a cross-shaped structure, and the transverse bracket 4 is fixedly connected to the condensation ring 5. In this way, the transverse bracket 4 can make the four groups of condensation rings 5 ​​below more stably fixed and avoid shaking of the condensation ring 5.

[0026] Specifically, such as Figure 3 and Figure 5 As shown, four groups of condensation rings 5 ​​of annular structure are provided at the bottom of the transverse bracket 4. The diameters of the four groups of condensation rings 5 ​​are different, and the four groups of condensation rings 5 ​​are distributed in a concentric circle structure at the bottom of the transverse bracket 4. The condensation rings 5 ​​distributed in this way can better contact with the passing gas, and then condense water vapor on the condensation rings 5, and then drip along the condensation column 502, which is convenient for collection and finally recycled.

[0027] Specifically, such as Figure 3 and Figure 5As shown, a connecting net 501 is distributed between the four groups of condensing rings 5, and the connecting net 501 is also fixedly connected to the horizontal bracket 4. The connecting net 501 can also increase the connection with the condensing ring 5, increase the area in contact with the gas, and prevent debris from falling from the top of the equipment into the interior of the cooling tower body 1;

[0028] Specifically, such as Figure 3 and Figure 5 As shown, a condensation column 502 is fixed to the bottom of the condensation ring 5 away from the horizontal bracket 4. The end of the condensation column 502 away from the condensation ring 5 is a conical structure, and the condensation columns 502 are evenly distributed at the bottom of the four groups of condensation rings 5. The conical structure at the bottom can facilitate the water condensed on the condensation column 502 to drip at the bottom of the condensation column 502.

[0029] Example 2, specifically, Figure 2 and Figure 4 As shown, a support 401 is vertically fixed in the middle of the horizontal bracket 4, and a filter box 6 is provided at the bottom of the support 401. The filter box 6 is a circular structure, and a filter screen 601 is provided on the top of the filter box 6. A cover plate 602 is fixed to the top of the filter screen 6 away from the filter box 6. A motor 603 is installed inside the cover plate 602. The filter box 6 can recycle the water accumulated at the bottom of the cooling tower body 1, and the filter screen 601 arranged above can filter the liquid. The filter screen 601 is arranged on the filter box 6 to avoid sucking away impurities deposited at the bottom of the liquid, making it convenient to recycle clean water for recycling.

[0030] Specifically, such as Figure 2 and Figure 4 As shown, the bottom of the motor 603 is connected to a cleaning scraper 604 with a rectangular frame structure, and a connecting column 605 is fixed in the middle of the cleaning scraper 604. The cleaning scraper 604 is connected to the inside of the filter box 6 for rotation. The motor 603 can drive the cleaning scraper 604 below to rotate inside the filter box 6 to avoid the accumulation of impurities inside the filter box 6, which leads to a lower efficiency of water recovery.

[0031] Specifically, such as Figure 2 and Figure 4 As shown, a brush structure is provided on the outer side surface of the connection between the cleaning scraper 604 and the filter box 6, and the width dimension of the cleaning scraper 604 is consistent with the diameter dimension inside the filter box 6. The provided brush structure can clean the impurities on the filter 601 to prevent the impurities on the filter 601 from being adsorbed on the filter 601 and clogging the filter 601. A drain pipe 606 is connected to the side of the filter box 6, and the drain pipe 606 is also connected to the circulation box 3.

[0032] When the embodiment of the present application is in use, a condensation ring 5 is provided at the bottom of the exhaust port 101 of the cooling tower body 1, and the condensation ring 5 is distributed on the inner side of the spray ring 302. In this way, when the spray ring 302 sprays water mist to cool the gas, the water mist will vaporize when it encounters the high-temperature gas. When it rises to the exhaust port 101, it will come into contact with the condensation ring 5, the connecting net 501, and the condensation column 502, which have a low temperature. When the water vapor encounters the surface of a cold object, it will condense, then drip along the condensation column 502, and finally accumulate at the bottom of the cooling tower body 1, thereby preventing the water vapor from leaving the cooling tower body 1 along with the gas.

[0033] A filter box 6 is provided at the bottom of the cooling tower body 1. The filter box 6 can allow water exceeding the height of the filter box 6 to enter the interior of the filter box 6 through the filter screen 601, and then be collected by the circulation box 3 from the drain pipe 606 and recycled. The interior of the filter box 6 is also provided with a cleaning scraper 604 driven by the motor 603 to rotate, so that the cleaning scraper 604 can rotate inside the filter box 6 and continuously clean the filter screen 601 to avoid impurities accumulating on the filter screen 601, resulting in reduced filtration efficiency. In this way, the condensed water can be recycled, thus forming an energy-saving circulating cooling tower. The use is completed. It should be noted that the utility model is an energy-saving circulating cooling tower. The components are all universal standard parts or components known to those skilled in the art. The structure and principle can be known to those skilled in the art through technical manuals or through conventional experimental methods.
