Description

Technical Field

[0001] The utility model specifically relates to a packing filtering device for a cooling tower and a cooling tower. Background Art

[0002] Data centers (or computer rooms) need to continuously consume a large amount of electric power resources and water resources. In particular, central air-conditioning chillers require a large amount of cooling water for heat exchange. However, dust may enter the cooling water circulation system in cooling towers (especially open cooling towers), and the packing of the cooling tower ages after several years of use, and the generated packing debris will enter the cooling water circulation system.

[0003] To address this situation, data centers need to frequently clean the cooling towers, consuming a large amount of fresh water. When cleaning the filters on the cooling water pipelines, the water in the pipelines will also be drained, resulting in waste of water resources, low water-saving rate, and an increase in the water usage efficiency index (Water Usage Effectiveness, WUE) of the data center.

[0004] In the prior art, the filtering systems of cooling towers in computer rooms generally focus on how to filter impurities in the cooling water or external impurities in the air, without considering filtering and related treatment of the packing debris of old cooling towers. And in the prior art, setting up a complete set of filtering devices to filter impurities in the cooling water will lead to excessive resistance in the water system, a decrease in water flow rate, etc. At the same time, the heat dissipation efficiency of the cooling tower decreases, resulting in an increase in power consumption. Or for example, in the prior art, a cooling water filtering device is set outside the cooling tower, which has disadvantages such as a relatively complex equipment structure and a large renovation difficulty, resulting in too high costs. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a packing filtering device for a cooling tower in view of the above deficiencies existing in the prior art, so as to solve the problems of incomplete consideration, difficult renovation, high cost, single function, etc. mentioned in the above background art.

[0006] In a first aspect, the utility model provides a packing filtering device for a cooling tower. The packing filtering device for the cooling tower includes a baffle, a filtering plate, and a support plate connected in sequence. The surface of the baffle is attached to the first inner side surface of the cooling tower. The support plate is arranged above the sump. The sump is arranged at the bottom of the cooling tower. The filtering plate is arranged between the water outlet of the packing and the sump.

[0009] Optionally, the distance between each overflow port of several overflow ports and the bottom of the sump is less than a preset cooling water level alarm threshold.

[0010] Optionally, the filter plate is provided with a plurality of filter holes arranged in an array between several overflow ports and the baffle. The aperture of the filter holes is greater than or equal to 1 mm and less than or equal to 2 mm.

[0011] Optionally, the support plate includes a first support plate and a second support plate. One end of the first support plate is connected to the second support plate, and the other end is connected to the filter plate.

[0017] For the packing filtering device of a cooling tower and the cooling tower provided by the embodiments of the present invention, considering the influence of external dust and internal packing debris of the cooling tower, a physical method is used to replace chemical agents, and the way for dust and packing debris to enter the cooling water system is actively cut off.

[0022] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by various orientation terms is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0024] Some embodiments of the present invention provide a packing filtration device for a cooling tower. As Figure 1 shown, the packing filtration device for the cooling tower (hereinafter simply referred to as the filtration device) includes a baffle 9, a filter plate 7, and a support plate 5 connected in sequence. The surface of the baffle 9 is attached to the first inner side surface 101 of the cooling tower 1. The support plate 5 is disposed above the sump 10. The sump 10 is disposed at the bottom of the cooling tower 1. The filter plate 7 is disposed between the water outlet of the packing 3 and the sump 10.

[0025] Exemplarily, the cooling tower 1 can be a closed cooling tower, an open cross-flow tower, or an open counter-flow tower.

[0026] Understandably, the baffle 9 is attached to the first inner side surface 101 of the cooling tower 1, and the support plate 5 is arranged above the sump 10, thereby fixing the filter plate 7 between the first inner side surface 101 of the cooling tower 1 and the sump 10. Moreover, the sump 10 is arranged at the bottom of the cooling tower 1, and the packing 3 is arranged between the first inner side surface 101 of the cooling tower and the maintenance passage 2. Then the filter plate 7 is fixed between the water outlet of the packing 3 and the sump 10. Thus, when the cooling tower 1 is operating, the cooling water flowing down from the packing 3 will flow through the filtering device, enter the sump 10 at the bottom of the cooling tower 1 only after being filtered by the filter plate 7, and flow out from the drain outlet 11. The old packing debris will also not be able to enter the sump of the cooling tower 1 due to the existence of the filtering device, thereby ensuring the clean, efficient, and zero-emission operation of the cooling water system and reducing the water consumption of the cooling tower.

[0027] Understandably, the baffle 9 is attached to the first side surface 101 of the cooling tower, which can not only aggregate the packing debris and external impurities, but also support and fix the filter plate 7.

[0028] Understandably, as Figure 1 shown, the packing 3 is symmetrically arranged on the left and right sides of the cooling tower 1, so the filtering device is also symmetrically arranged on the left and right sides of the cooling tower 1.

[0029] Understandably, in order to deal with the support columns existing in a small amount in the center of the cooling tower, the shape of the support plate 5 can be set as needed. For example, the support plate 5 is concave (bent in the opposite direction of the support column) at the position blocked by the support column of the cooling tower to avoid the blockage of the support column. Or for example, while keeping the width of the support plate 5 unchanged, the length of the support plate 5 is reduced (the support plate 5 is not arranged at the position with the support column), reducing the possibility of contact with the support column inside the cooling tower.

[0030] In some embodiments, as Figure 1 shown, the end of the filter plate 7 close to the support plate 5 is higher than the end of the filter plate 7 close to the baffle 9. The filter plate 7 is arc-shaped, and the arc bulges towards the bottom of the cooling tower 1.

[0031] Understandably, the end of the filter plate 7 close to the support plate 5 being higher than the end of the filter plate 7 close to the baffle 9 can cause impurities such as packing debris to accumulate towards the end close to the baffle 9 under the action of gravity, so as to prevent impurities such as packing debris from blocking the filter holes on the filter plate 7. The filter plate 7 is arc-shaped, and the arc bulges towards the bottom of the cooling tower 1, then the volume of the accumulation of impurities such as packing debris can be increased at the end close to the baffle 9, so as to prevent the filter holes on the filter plate 7 from being blocked due to too many impurities such as packing debris.

[0032] In some embodiments, as Figure 1 shown, several overflow ports 6 are arranged on the part of the filter plate 7 close to the support plate 5.

[0033] Understandably, when the filter holes on the filter plate 7 are blocked, the cooling water can automatically flow into the cooling tower sump 10 from multiple overflows 6, which can avoid accidents and losses caused by water shortage in the cooling tower due to blockage.

[0034] In some embodiments, the distance between each overflow 6 in a plurality of overflows 6 and the bottom of the sump 10 is less than a preset cooling water level alarm threshold.

[0035] Understandably, setting a plurality of overflows 6 at a position lower than the preset cooling water level alarm threshold can avoid false alarms caused by blockage and increase the workload of the staff. The distance between each overflow in a plurality of overflows 6 and the bottom of the sump 10 can be set according to the actual situation of the cooling tower. Exemplarily, the difference between the distance between each overflow in a plurality of overflows 6 and the bottom of the sump 10 (i.e., the liquid level height where each overflow in a plurality of overflows 6 is located) and the preset cooling water level alarm threshold is less than or equal to 3 cm.

[0036] In some embodiments, the filter plate 7 is provided with a plurality of filter holes arranged in an array between a plurality of overflows 6 and the baffle 9. The aperture of the filter holes is greater than or equal to 1 mm and less than or equal to 2 mm.

[0037] Exemplarily, as Figure 2 shown, the filter plate 7 can be provided with a mounting hole between a plurality of overflows 6 and the baffle 9, and a filter net 71 is installed in the mounting hole. The filter holes on the filter net 71 are arranged in an array. In this way, the cooling water flows out from the packing water outlet and reaches the sump 10 after passing through the filtration of the filter net 71. For example, the filter net 71 can be a special filter net for the air-conditioning water system with fine filter holes, which can filter impurities, packing debris and external air impurities in the cooling water well.

[0038] In some embodiments, as Figure 1 shown, the support plate 5 includes a first support plate 51 and a second support plate 52. One end of the first support plate 51 is connected to the second support plate 52, and the other end is connected to the filter plate 7. The second support plate 52 is horizontally arranged at the edge of the maintenance passage 2, and the maintenance passage 2 is arranged above the sump 10.

[0039] Understandably, the support plate 5 and the baffle 9 can fix the filter plate 7 between the maintenance passage 2 and the first side surface 101 of the cooling tower 1, which can not only provide support to prevent the filter device from shifting left and downward, but also prevent impurities in the external air from entering the sump 10. The impurities in the air will be blocked by the filter device outside the sump 10 and finally precipitate near the baffle 9 together with the packing debris, so as to reduce the influence of external impurities on the cooling water.

[0040] In some embodiments, a plurality of handles 4 are provided on the second support plate 52, and the plurality of handles 4 are spaced apart.

[0041] Understandably, the handles can be grasped by maintenance personnel to apply force. When the maintenance personnel hold one handle with each hand, it is easier to move, clean, and perform other maintenance operations on the filtration device, thereby facilitating the maintenance of the filtration device by the maintenance personnel after a certain usage period.

[0042] Exemplarily, the distance between each of the plurality of handles 4 can be greater than or equal to 45 cm and less than or equal to 60 cm.

[0043] In some embodiments, as Figure 3 shown, the filtration device further includes a gap filling member 20, and the gap filling member 20 is disposed in the gap between the filtration device and the second inner side 102 of the cooling tower 1, and the second inner side 102 of the cooling tower 1 is connected to the first inner side 101 of the cooling tower 1.

[0044] Understandably, under the dual action of the support plate 5 and the baffle 9, the filtration device can be well fixed below the packing 3, and the baffle 9 is attached to the first inner side 101 of the cooling tower 1, so there is no gap between the filtration device and the first inner side 101 of the cooling tower 1. The gap filling member 20 is disposed in the gap between the second inner side 102 of the cooling tower 1 and the filtration device to prevent foreign objects from flowing into the sump 10 through the gap between the second inner side 102 of the cooling tower 1 and the filtration device.

[0045] Exemplarily, as Figure 3 shown, the cooling tower 1 is rectangular parallelepiped-shaped, and the second inner side 102 of the cooling tower 1 can include two sides connected to the first inner side 101 of the cooling tower 1.

[0046] In some embodiments, as Figure 4 shown, the gap filling member 20 includes a curved blocking portion 202, and the blocking portion 202 bends inward to form a recessed portion 201. The edges of the baffle 9 and the filter plate 7 close to the second inner side 102 of the cooling tower 1 are snapped into the recessed portion 201 and the back of the blocking portion 202 is abutted against the second inner side 102 of the cooling tower 1.

[0047] Exemplarily, the gap filling member 20 can be a water blocking strip, and the water blocking strip is generally made of rubber or silicone material, which has good sealing performance and can block the gap between the second inner side 102 of the cooling tower 1 and the filtration device, more effectively preventing foreign objects from flowing into the sump 10 through the gap between the second inner side 102 of the cooling tower 1 and the filtration device.

[0048] Exemplarily, a gap filling member 20 may also be provided at the edge of the second inner side surface 102 of the support plate 5 close to the cooling tower 1, which can prevent impurities from flowing into the gap between the support plate 5 and the second inner side surface 102 of the cooling tower 1 and entering the sump in some special cases (such as the blockage of the drain port, etc.) along with the cooling water.

[0049] It can be understood that the support plate 5 is arranged at a position higher than the water surface of the sump. If the cooling tower operates normally, generally no cooling water will flow through the support plate 5, so the gap filling member may not be provided at the edge of the second inner side surface 102 of the support plate 5 close to the cooling tower 1.

[0050] In some embodiments, as Figure 3 shown, the gap filling member 20 further includes a plurality of serrations 2011, and the plurality of serrations 2011 are arranged opposite to and staggered at the entrance of the recess 201, and the bottoms of the plurality of serrations 2011 are connected to the inner curved surface of the blocking portion 202.

[0051] It can be understood that the serrations 2011 can fill the gap between the recess 201 and the baffle 9 and the filter plate 7 to prevent foreign objects from entering the recess 201 and causing damage to the baffle 9, the filter plate 7 or the support plate 5, and can prevent foreign objects from entering the sump through the gap between the recess 201 and the baffle 9 and the filter plate 7 and causing pollution to the cooling water in the sump.

[0052] A packing filtration device for a cooling tower provided by the present utility model can, when an old cooling tower in a data center operates, the cooling water flowing down from the packing enters the filtration device, and after being filtered by the filter plate, it flows out of the lower sump of the cooling tower. The old packing debris and impurities in the external air will also be filtered by the filtration device and finally settle near the baffle together, thereby reducing the influence of the packing debris and external impurities on the cooling water. This filtration device solves the problems of incomplete consideration and single function in the prior art of the cooling tower filtration system. Through the operation of this packing filtration device, three substances, namely impurities in the cooling water, packing debris, and impurities in the external air, can be filtered simultaneously, with more comprehensive consideration and more diverse functions. It can effectively ensure the clean, efficient, and zero-emission operation of the cooling water system and reduce the water consumption of the cooling tower.

[0053] A packing filtration device for a cooling tower provided by the present utility model has an independent structure and can be used without any modification to the original old cooling tower at the data center, which can greatly reduce the modification difficulty and the modification cost required for the modification. In addition, the raw materials of this packing filtration device are relatively inexpensive, and the cost of each component plate is less, so the cost can be well controlled, solving the problems of difficult modification and high cost in the prior art of the cooling tower filtration system at the data center. Through the operation of this packing filtration device, unnecessary modifications can be greatly reduced, and unnecessary cost expenditures can be greatly reduced.

[0054] A packing filtration device for a cooling tower provided by the utility model facilitates the filtration and precipitation of impurities through the curvature of the filter plate, and facilitates the support and fixation of the filtration device through baffles, support plates, and handles. The structure is delicate but maximally reduces the input of human and material resources. Without the participation of human, electrical, mechanical and other material resources, it can efficiently and automatically complete the filtration of three kinds of impurities. In the new era when the dual-carbon goal is urgent, it is of great significance for achieving zero emissions and guiding resources to continuously contribute to the clean field. Through the above relatively slender overall structure design of the filtration device, maintenance personnel can easily push in and pull out the filtration device under the packing, which greatly facilitates the daily maintenance work of maintenance personnel.

[0055] In summary, a packing filtration device for a cooling tower provided by the utility model is low-cost, does not require transformation, saves energy and reduces carbon, has high filtration efficiency, diverse functions, and is green and environmentally friendly. It meets the actual needs of current data centers for energy conservation and water conservation, realizes the efficient utilization of cooling water on the cooling tower side, reduces the water consumption of the cooling tower, improves the water resource utilization efficiency of the data center, and improves the water use efficiency (WUE) and power utilization efficiency (Power Usage Effectiveness, PUE) of the data center.

[0056] Some embodiments of the utility model provide a cooling tower, and the above-mentioned packing filtration device for the cooling tower is arranged inside the cooling tower.

[0057] The specific solutions and beneficial effects of the cooling tower provided by some embodiments of the utility model can refer to the relevant descriptions of the above-mentioned packing filtration device for the cooling tower, which will not be elaborated here.

[0058] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the utility model. However, the utility model is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the utility model, and these modifications and improvements are also regarded as the protection scope of the utility model.
