Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, and particularly to a fog-eliminating water collection device and a cooling tower. Background Technique

[0002] The function of a cooling tower is to conduct heat exchange between the circulating water carrying waste heat and air in the tower. During the heat exchange process, the heat of the circulating water is transferred to the air and finally incorporated into the atmosphere, achieving the purpose of cooling the circulating water.

[0003] In the prior art, a Chinese patent with the publication number CN216644999U discloses a closed-type water-saving fog-eliminating cooling tower, which includes a tower body with air inlets opened on opposite side walls, and a heat exchange member, a water spraying assembly, and a water collector installed in the tower body in sequence from bottom to top. The air inlets are located below the heat exchange member. Both ends of the heat exchange member are respectively communicated with a water inlet pipe and a water outlet pipe. The water spraying assembly includes a water tank arranged at the bottom of the tower body, a water spraying pipe communicated with the water tank, a spray pipe communicated with the water spraying pipe, and a plurality of nozzles evenly arranged at equal intervals on the spray pipe. The nozzles are arranged facing the heat exchange member. During use, external dry cold air enters the tower body through the air inlets. The liquid sprayed by the nozzles forms a very thin water film on the heat exchange member. The water film contacts the heat exchange member, so that the temperature of the water film can be reduced to a certain extent. At the same time, after the cooled water film exchanges heat with the dry cold air, a part of it generates humid hot air, and the other part forms liquid drops that fall into the water tank. However, the liquid drops falling into the water tank will pass through the external cold air and thus contact the external cold air, which increases the burden of fog elimination.

Detailed Embodiments

[0024] The present utility model will now be described in detail with reference to the drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present utility model in a schematic manner, so it only shows the components related to the present utility model.

[0025] Please refer to Figures 1 to 5 , the present utility model provides a cooling tower, which includes a tower body 1 and a demisting and water collection device. The demisting and water collection device includes a demisting module 2 and a water collection assembly 3. The demisting module 2 is detachably arranged in the tower body 1, and the water collection assembly 3 is arranged at the bottom of the demisting module 2.

[0026] The demisting module 2 is formed by stacking a plurality of packing sheets 20. Each packing sheet 20 includes a first mounting surface 201 and a second mounting surface 202. The first mounting surface 201 is connected to the second mounting surface 202 of the adjacent packing sheet 20.

[0027] A plurality of channels are provided on each packing sheet 20. Each packing sheet 20 includes a first diversion section 21, an interception section 22, a second diversion section 23 and an adhesion section 24 which are connected to each other. The surfaces of the first diversion section 21, the second diversion section 23 and the adhesion section 24 are all in a corrugated structure. The surfaces of the first diversion section 21 and the second diversion section 22 are both provided with staggered grooves 211 and protrusions 212. The channels are formed by the grooves 211, so as to increase the flow area of the water film or water droplets, and further improve the heat exchange effect. Further, the corrugations on the first diversion section 21 and the corrugations on the second diversion section 22 are both inclined, so as to extend the flow time of the water film or water droplets on the packing sheet 20. In this embodiment, the inclination directions of the corrugations on the first diversion section 21 are the same as those of the corrugations on the second diversion section 22.

[0028] There are multiple first diversion sections 21, interception sections 22, second diversion sections 23 and adhesion sections 24. A connected first diversion section 21, interception section 22, second diversion section 23 and adhesion section 24 form a packing unit. The corrugations of the first diversion sections 21 on two adjacent packing units are arranged in a mirror image, so as to increase the flow path of the water film or water droplets, and further improve the heat exchange effect of the demisting module 2.

[0029] The interception section 22 is in a planar structure. The interception section 22 is arranged between the first diversion section 21 and the second diversion section 23. The grooves 211 between the first diversion section 21 and the second diversion section 23 are intercepted by the interception section 22, so as to increase the flow path of the water film or water droplets, increase the residence time of the water film or water droplets on the packing sheet 20, and further improve the heat exchange effect of the demisting module 2.

[0030] Further, the adhesion section 24 is connected to one end of the second diversion section 23 away from the interception section 22. The corrugations on the surface of the adhesion section 24 are in the vertical direction. The adhesion section 24 is in an arc shape and protrudes outward. A first boss 241 protrudes outward on the first mounting surface 201 of the adhesion section 24, so that a first concave platform is formed on the second mounting surface 202 of the adhesion section 24. A second concave platform 242 is formed by inward depression on the first mounting surface 201 of the adhesion section 24, so that a second boss is formed on the second mounting surface 202 of the adhesion section 24. In this embodiment, the first boss 241 and the first concave platform on the adhesion section 24 are arranged in half. During installation, the first boss 241 on any packing sheet 20 cooperates with the first concave platform on the adjacent packing sheet 20, and the second concave platform 242 on any packing sheet 20 cooperates with the second boss on the adjacent packing sheet 20.

[0031] Further, the packing sheet 20 further includes a water collection section 25. The water collection section 25 is located at the bottommost section of the packing sheet 20. The water collection section 25 is generally in a triangular structure with openings at both the upper and lower ends. The water collection section 25 includes a large-mouth end 251 and a small-mouth end 252. The large-mouth end 251 is connected to the first diversion section 21, and the small-mouth end 252 is connected to the water collection assembly 3. During use, the water droplets of the sprayed water that enter the groove 212 of the demisting module 2 reach the small-mouth end 252 through entering from the large-mouth end 251, so that the water droplets of the sprayed water can converge at the small-mouth end 252 and flow out from the small-mouth end 252 into the water collection assembly 3.

[0032] The water collection assembly 3 includes a water collection member 31 and a support member 32. The support member 32 is disposed inside the water collection member 31. The cross-section of the water collection member 31 is in a U-shaped structure. The water collection member 31 includes a bottom plate 311, a first baffle 312, and a second baffle 313. The first baffle 312 and the second baffle 313 are respectively disposed on opposite sides of the bottom plate 311, and the length dimensions of the first baffle 312 and the second baffle 313 are the same as the length dimension of the bottom plate 311. The support member 32 is disposed on the bottom plate 311. The support member 32 is in a square tubular structure, and the length dimension of the support member 32 is the same as the length dimension of the bottom plate 311. Specifically, the support member 32 includes an upper end plate 321 and a lower end plate 322 that are oppositely disposed and a first side wall 323 and a second side wall 324 that are oppositely disposed. The upper end plate 321 is in contact with the water collection section 25, and the lower end plate 322 is connected to the water collection member 31. Specifically, the upper end plate 321 is in contact with the small-mouth end 252 and is used to support the small-mouth end 252. The lower end plate 322 is connected to the bottom plate 311. The first side wall 323 and the second side wall 324 are connected to opposite sides of the upper end plate 321 and the lower end plate 322. By providing the support member 32, on the one hand, it can support the demisting module 2, and on the other hand, it can reduce the damage to the surface of the water collection member 31 caused by the sprayed water. During use, the water droplets of the sprayed water that enter the groove 212 of the demisting module 2 reach the small-mouth end 252 through entering from the large-mouth end 251, so that the water droplets of the sprayed water can converge at the small-mouth end 252 and flow out from the small-mouth end 252 to the upper end plate 321, and then flow into the water collection member 31 through the first side wall 323 and the second side wall 324 and flow out from both ends of the water collection member 31.

[0033] Further, there are multiple water collection assemblies 3. The multiple water collection devices 3 are arranged at a certain distance, so as to form spaced-apart rain areas, thereby reducing the contact area between the outside cold air and the sprayed water rain area and improving the demisting effect.

[0034] In this embodiment, the water collection member 31 is made of carbon steel material. In other embodiments not shown, the water collection member 31 can also be made of stainless steel material.

[0035] During use, the water droplets entering the groove 212 of the demisting module 2 reach the small-mouth end 252 from the large-mouth end 251. Thus, after the water droplets converge at the small-mouth end 252 and flow out of the small-mouth end 252 to the upper end plate 321, they flow into the water collecting member 31 through the first side wall 323 and the second side wall 324, and flow out from both ends of the water collecting member 31.

[0036] The demisting and water collecting device or cooling tower provided by the present utility model enables the water droplets entering the groove 212 of the demisting module 2 to enter the water collecting section 25. Thus, after the water droplets flow out of the water collecting section 25 to the upper end plate 321, they flow into the water collecting member 31 through the first side wall 323 and the second side wall 324, and flow out from both ends of the water collecting member 31, thereby reducing the contact area between the outside cold air and the water spraying rain area and improving the demisting effect.

[0037] Inspired by the ideal embodiments of the present utility model described above, through the above description, relevant staff can make various changes and modifications without departing from the scope of the present utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
