Description

Technical Field

[0001] The invention relates to the technical field of cooling towers, in particular to a bottom water inlet structure of a water distribution tray of a cross-flow cooling tower. Background Art

[0002] 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. It uses the heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature. The device is generally barrel-shaped, hence the name cooling tower.

[0003] Cross-flow cooling tower is a type of cooling tower. Water flows vertically from the top of the tower, and air flows horizontally through the water-sprinkling filler. The airflow and water flow are perpendicular to the cooling tower. According to the quality of cooling water, it can be divided into open tower and closed tower. According to the noise level, it can be divided into ordinary type, low noise type, ultra-low noise type, and industrial type.

[0004] The existing cooling tower needs to replenish the water inside the water distribution tray when in use. During the replenishment, due to the presence of a protrusion on the bottom wall of the water distribution tray, the cooling water will be preferentially distributed to the bottom wall body which is at a lower position than the protrusion. However, due to the obstruction of the protrusion, the position located in the water inlet area will be replenished with cooling water first. In this process, the area far from the water inlet may experience a shortage of cooling water, resulting in the inability to effectively distribute water in this area, which in turn leads to uneven water distribution.

[0026] Specifically, when in use, the delivery pump 802 sucks the water inside the water collecting tray 17 into the water drawing frame 803, and then delivers it to the inside of the filter seat 801. At this time, the water will pass through the dust filter plate 810 for filtering, and the power motor 806 is started during filtering, and the power motor 806 can drive the raised ring frame 805 to rotate. Since the contact ring frame 807 contacts the raised ring frame 805 under the drive of the telescopic spring 812, the telescopic spring 812 can reciprocate with the rotation of the raised ring frame 805, and then the contact ring frame 807 drives the filter inner frame 808 to vibrate, so as to further vibrate the dust filter plate 810 to avoid dust clogging; In a specific application scenario, the circulating filter module 8 is suitable for the cooling water circulation link, that is, the circulating filter module 8 can filter the dust inside it during the cooling water recycling process, thereby increasing the cleanliness of the cooling water during circulation, and preventing dust from falling on the filler 7 with the cooling water, thereby increasing the use effect of the device, and when filtering, the circulating filter module 8 can vibrate, so that the internal filter inner frame 808 drives the dust filter plate 810 to vibrate, thereby preventing dust from clogging the filter plate, so as to increase the filtering effect of the device, and at the same time, when cleaning dust, the device can also rotate to assist in dust cleaning.

[0027] Working principle: When replenishing water, the water replenishment pipe 13 transports cooling water to the inside of the water frame seat 602, and transports it to the inside of the delivery pipe 603 through the water frame seat 602, so that the connecting hose 607 transports water to the inside of the water replenishment nozzle 605, so that it is sprayed out through the water replenishment nozzle 605 for replenishing water. In this process, as the water flow flows, it can drive the driving impeller 619 to rotate, and then the driving impeller 619 drives the connecting shaft 620 and the worm gear 610 to rotate. Since the worm gear kit 612 is meshed with the worm gear 610, the worm gear 610 drives the worm gear kit 612 to rotate, and then drives the installation shaft 609 and the transmission wheel 611 to rotate. At this time, the transmission wheel 611 can cooperate with the transmission belt 604 to drive the driven wheel 614 and the fixed The shaft 615 rotates, and the fixed shaft 615 drives the toothless gear 613 to rotate. Since the toothless gear 613 is meshed with the transmission gear 617, the toothless gear 613 can drive the transmission gear 617 and the mounting rod 618 to rotate. At the same time, the torsion spring 616 is twisted and deformed, and then drives the mounting seat 606 and the water replenishment nozzle 605 to rotate to change the water replenishment position. When it rotates to a certain position, the toothless gear 613 will be temporarily separated from the transmission gear 617. At this time, the torsion spring 616 is restored, and then drives the mounting seat 606 and the water replenishment nozzle 605 to reset, so that the water replenishment position is restored. Then, the process is repeated, so that the water replenishment nozzle 605 swings back and forth, so that the water replenishment amount is more uniform, until the water replenishment is completed; When in use, the delivery pump 802 sucks the water inside the water collecting tray 17 into the water drawing frame 803, and then delivers it to the inside of the filter seat 801. At this time, the water will pass through the dust filter plate 810 for filtering, and the power motor 806 is started during filtering. The power motor 806 can drive the raised ring frame 805 to rotate. Since the contact ring frame 807 contacts the raised ring frame 805 under the drive of the telescopic spring 812, the telescopic spring 812 can reciprocate with the rotation of the raised ring frame 805, and then the contact ring frame 807 drives the filter inner frame 808 to vibrate, so as to further vibrate the dust filter plate 810 to avoid dust clogging; During replacement, the electric telescopic rod 903 is started, and the electric telescopic rod 903 drives the connecting plate 906 and the sealing cover plate 902 to move, so that the filter ring frame 804 moves out of the filter seat 801, and then the drive motor 912 is started, and the drive roller 905 is driven by the drive motor 912 to rotate, so that another filter ring frame 804 rotates to the top of the filter seat 801, and then the electric telescopic rod 903 is controlled to move the filter ring frame 804 to the inside of the filter seat 801 to complete the replacement; When cleaning, the electric telescopic rod 903 is adjusted so that the connecting plate 906 and the sealing cover plate 902 drive the filter ring frame 804 to tilt, and then the electric push rod 914 is started, and the electric push rod 914 drives the cleaning cylinder 907 to move to the inside of the filter ring frame 804, and then the electric rod 910 is started, so that the electric rod 910 drives the magnetic suction kit 911 to contact and adsorb the magnetic suction block 811, and then drives the rod to reset, so that the dust filter plate 810 moves out of the filter inner frame 808 for cleaning; After cleaning, the dust will fall into the interior of the cleaning tube 907 , and the staff can regularly conduct centralized cleaning through the discharge pipe opening 908 , the discharge pipe fitting 913 and the bellows 909 .
