Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cooling tower technology, specifically relating to a crossflow closed cooling tower. Background Technology
[0002] A crossflow closed-circuit cooling tower is a cooling device that achieves heat exchange through the transverse crossflow of air and water. During long-term use, dust and debris in the air adhere to the surface of the packing material, or scale deposits due to poor water quality can clog the gaps in the packing material, hindering airflow and water film formation. This leads to a decrease in heat exchange efficiency and a decline in the overall heat exchange efficiency of the crossflow closed-circuit cooling tower, affecting its normal operation. Utility Model Content
[0003] This utility model provides a crossflow closed cooling tower, which can make the path of air and water flow through the packing plate more tortuous and prolong the contact time, which can help promote the exchange of heat and matter. At the same time, the combination of wide-mouth grooves and "V"-shaped grooves can further enhance the heat exchange efficiency and reduce the possibility of blockage.
[0004] To achieve the above objectives, a crossflow closed-circuit cooling tower includes a crossflow closed-circuit cooling tower body. A packing assembly is installed inside the crossflow closed-circuit cooling tower body on the side near the air inlet. The packing assembly includes several inclined packing plates, several elastic rubber sleeves, and several connecting columns. The several elastic rubber sleeves are respectively fixedly connected to the outer edges of the several packing plates, and the several packing plates are fixedly connected to each other by the several connecting columns.
[0005] Preferably, the top of the packing plate is provided with a plurality of "V" shaped grooves, and the top of the "V" shaped grooves is provided with a wide-mouth groove, which is connected to the "V" shaped grooves.
[0006] Preferably, the outer wall of the filler plate is provided with an installation groove, and the elastic rubber sleeve is embedded inside the installation groove.
[0007] Preferably, there are intersecting guide rods between two adjacent wide-mouth slots, and the guide rods are embedded in the top of the packing plate.
[0008] Preferably, a reinforcing rod is fixedly connected between the two intersecting guide rods.
[0009] The present invention has the following beneficial effects: the inclined packing plate makes the path of air and water flow through the packing plate more tortuous and prolongs the contact time, which helps to promote the exchange of heat and matter. At the same time, the cooperation between the wide-mouth groove and the "V"-shaped groove can further enhance the heat exchange efficiency and reduce the blockage. Attached Figure Description

[0014] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0015] Example 1:
[0016] like Figure 1 As shown in Figure 3: A crossflow closed-loop cooling tower includes a crossflow closed-loop cooling tower body 1. A packing assembly 2 is installed inside the crossflow closed-loop cooling tower body 1 near the air inlet. The packing assembly 2 includes several inclined packing plates 21, several elastic rubber sleeves 22, and several connecting posts 23. The elastic rubber sleeves 22 are respectively fixedly connected to the outer edges of the packing plates 21, and the packing plates 21 are fixedly connected to each other by the connecting posts 23. Several "V"-shaped grooves 212 are formed on the top of the packing plates 21, and a wide-mouth groove 211 is formed on the top of the "V"-shaped grooves 212. The wide-mouth groove 211 communicates with the "V"-shaped grooves 212. An installation groove is formed on the outer wall of the packing plates 21, and the elastic rubber sleeves 22 are embedded in the grooves. The installation slot has intersecting guide rods 213 between two adjacent wide-mouth slots 211, and the guide rods 213 are embedded in the top of the packing plate 21. A reinforcing rod 214 is fixedly connected between two intersecting guide rods 213. The top of the packing plate 21 has several "V"-shaped slots 212, and the top of the "V"-shaped slots 212 has wide-mouth slots 211. The wide-mouth slots 211 are connected to the "V"-shaped slots 212. The outer wall of the packing plate 21 has an installation slot, and an elastic rubber sleeve 22 is embedded in the inside of the installation slot. Intersecting guide rods 213 are intersecting between two adjacent wide-mouth slots 211, and the guide rods 213 are embedded in the top of the packing plate 21. A reinforcing rod 214 is fixedly connected between two intersecting guide rods 213.
[0017] In this technical solution: the crossflow closed cooling tower body 1 is the entire cooling tower body, and the packing assembly 2 is the packing component in the cooling tower. Several packing plates 21 are set at an incline, which makes the path of air and water flow through the packing plates 21 more tortuous and prolongs the contact time, which helps to promote the exchange of heat and matter. At the same time, when air passes through the packing plates 21 laterally, the inclined packing plates 21 can increase the contact area, making it easier for the air to carry away the heat of water evaporation and enhance the cooling effect. In addition, the inclined packing plates 21 can make the water film formed on the plate more evenly distributed, increase the contact area with air, improve the heat exchange efficiency, and the incline allows the water film to have a certain flow speed, which is fast and facilitates heat transfer. At the same time, the turbulence of air passing through the inclined packing plates 21 is enhanced, which can break the air boundary layer, accelerate heat transfer, and make the heat exchange between air and water film more efficient. The inclined packing plates 21 can make impurities slide down the plate with the water flow, making it difficult to accumulate and reducing the risk of blockage. At the same time, the continuous flow of water can also carry away some impurities, so that the packing plates 21 maintain a good working condition.
[0018] The wide-mouth groove 211 and the "V"-shaped groove 212 formed on the surface of the packing plate 21 create through holes with a larger top diameter and a smaller bottom diameter. At this point, the larger upper diameter allows water to be stored and expanded to form a thick water film, enhancing sensible heat exchange; the lower "V"-shaped constriction accelerates flow, forming a high-speed thin water film, enhancing evaporative heat dissipation. Simultaneously, when water flows through the lower "V"-shaped groove 212, the cross-sectional contraction generates turbulent disturbances, disrupting the water film boundary layer and accelerating heat transfer. Furthermore, when large particles of impurities... After silt, fibers, and other impurities enter the upper large hole with the water flow, large particles can quickly slide down to the bottom of the packing under the action of gravity and water flow scouring. Small particles can be carried away by the turbulence and discharged with the water film renewal, which helps to reduce the risk of clogging. In addition, the contraction structure of the "V" shaped hole of the "V" shaped groove 212 makes it easier for the high-pressure flushing water to form a "jet effect". During flushing, impurities can be subjected to the dual action of impact force and water flow reverse thrust, which helps to improve flushing efficiency.
[0019] The guide rod 213 set on the top of the packing plate 21 is used to guide the two adjacent wide slots 211. At this time, the guide rod 213 acts as an air diversion rib, which can force the transverse airflow to pass through the channel and contact the water film, avoid air short circuit, and help improve air utilization. The guide rod 213 can guide the spray water to converge into the "V" shaped slot, eliminate the "dry area" on the packing surface, ensure water film coverage in the whole area, and help improve the effective heat exchange area of the packing.
[0020] The elastic rubber sleeve 22 located at the outer edge of the packing plate 21 is made of elastic rubber material, which can absorb the deformation of the packing plate 21 caused by temperature changes during use, and prevent the packing plate 21 from warping or cracking. At the same time, during use, the elastic edge vibrates slightly with the airflow and water flow, which helps to shake off the attached scale, microorganisms, etc., and helps to reduce the amount of biofilm attached. The elastic rubber sleeve 22 can be made of silicone rubber.
[0021] The working principle of this technical solution is as follows: During use, when water flows over the surface of the packing plate 21, it can fill the entire surface of the packing plate 21 under the guidance of the wide-mouth groove 211 and the "V"-shaped groove 212. The inclined packing plate 21 can make the water film formed on the plate more evenly distributed, increase the contact area with air, and improve the heat exchange efficiency.
