Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a water distribution control device for a cooling tower. Background Art

[0002] During the exchange of cold air and circulating cooling water within a mechanical draft cooling tower, the cold air undergoes heat exchange with the circulating water and becomes saturated, moist, and hot air. During periods of cold ambient temperature, when the mechanical draft cooling tower is operating, this saturated, moist, and hot air is discharged from the tower and mixed with the cold air. This cooling and condensation form a mist cloud containing numerous tiny liquid particles. With increasing environmental protection requirements, the need for mist removal from cooling towers is also increasing. Due to the low height of mechanical draft cooling towers, the drifting mist cloud affects visibility in surrounding residential areas and on roads, disrupting the urban environment and causing humidity to rise in downwind areas. Furthermore, the plume plume that settles on the ground makes the roads around the cooling tower slippery or icy, impacting factory safety, affecting the safe operation and service life of surrounding production equipment, and posing a significant safety hazard to surrounding traffic. As the government's environmental regulations become increasingly stringent, clear requirements for mist reduction have been established for open-type cooling towers. With the growing importance of environmental protection, the elimination of mist plume from cooling towers is becoming increasingly important.

[0003] In existing technology, conventional cooling towers can be modified to switch between multiple operating modes by installing defogging modules and blinds. Switching to defogging mode in winter can significantly reduce rain and fog at the cooling tower outlet, greatly improving the environment around the cooling tower and being environmentally friendly. Although this control method can switch the defogging mode, it is relatively complex. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0025] See also Figures 1 to 6 The utility model provides a water distribution control device for a cooling tower, which includes a tower body 1, a mist elimination module 2 and a water distribution system 3. The mist elimination module 2 is detachably arranged in the tower body 1, and the water distribution system 3 is arranged above the mist elimination module 2.

[0026] The mist elimination module 2 is formed by stacking a plurality of filler sheets 20 . Each filler 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 filler sheet 20 .

[0027] Each packing sheet 20 is provided with multiple channels. Each packing sheet 20 also includes an interconnected first guide section 21, an intercepting section 22, a second guide section 23, and an adhesive section 24. The surfaces of the first guide section 21, the second guide section 23, and the adhesive section 24 all have a corrugated structure. The surfaces of the first guide section 21 and the second guide section 22 are provided with interlaced grooves 211 and protrusions 212. The channels are formed by the grooves 211, thereby increasing the circulation area of the water film or water droplets, thereby improving the heat exchange effect. Furthermore, the corrugations on the first guide section 21 and the second guide section 22 are both inclined, thereby extending the flow time of the water film or water droplets on the packing sheet 20. In this embodiment, the inclination direction of the corrugations on the first guide section 21 is the same as the inclination direction of the corrugations on the second guide section 22.

[0028] There are multiple first guide sections 21, interception sections 22, second guide sections 23 and bonding sections 24. A first guide section 21, interception section 22, second guide section 23 and bonding section 24 connected to each other constitute a packing unit. The corrugations of the first guide sections 21 on two adjacent packing units are mirror-imaged, thereby increasing the flow path of the water film or water droplets, thereby improving the heat exchange effect of the demisting module 2.

[0029] Furthermore, an installation groove 213 is provided on the top of the demisting module 2. The installation groove 213 is located on the side of the first guide section 21 at the top away from the interception section 22. The cross-section of the installation groove 213 is a V-shaped structure. A porous plate 4 is provided in the installation groove 213, and the two ends of the porous plate 4 are flush with the two ends of the demisting module 2.

[0030] The interception section 22 is a planar structure. The interception section 22 is arranged between the first guide section 21 and the second guide section 23. The interception section 22 intercepts the groove 211 between the first guide section 21 and the second guide section 23, thereby increasing the flow path of the water film or water droplets, and increasing the residence time of the water film or water droplets on the filler sheet 20, thereby improving the heat exchange effect of the demisting module 2.

[0031] Furthermore, the bonding section 24 is connected to the end of the second diversion section 23 away from the intercepting section 22. The corrugations on the surface of the bonding section 24 are vertically oriented. The bonding section 24 is arc-shaped and protrudes outward. A first boss 241 protrudes outward from the first mounting surface 201 of the bonding section 24, thereby forming a first recessed platform on the second mounting surface 202 of the bonding section 24. A second recessed platform 242 is recessed inwardly on the first mounting surface 201 of the bonding section 24, thereby forming a second boss on the second mounting surface 202 of the bonding section 24. In this embodiment, the first boss 241 and the first recessed platform 242 on the bonding section 24 are arranged in half. During installation, the first boss 241 on any filler sheet 20 cooperates with the first recessed platform on the adjacent filler sheet 20, and the second recessed platform 242 on any filler sheet 20 cooperates with the second boss on the adjacent filler sheet 20.

[0032] Furthermore, the packing sheet 20 further includes a water collection section 25, which is located at the bottom of the packing sheet 20. The water collection section 25 is generally triangular in shape with openings at both the upper and lower ends. The water collection section 25 includes a large opening 251 and a small opening 252. The large opening 251 is connected to the first flow guide section 21, and the small opening 252 is connected to the water collection assembly 3. During use, water droplets entering the groove 212 of the mist elimination module 2 enter from the large opening 251 and reach the small opening 252, so that the water droplets can converge at the small opening 252 and then flow out from the small opening 252.

[0033] The water distribution system 3 includes a conventional water distribution component 31 and a fog-eliminating water distribution component 32. The conventional water distribution component 31 includes a water distribution main pipe 311, a water distribution branch pipe 312 and a nozzle (not shown in the figure). There are multiple water distribution branch pipes 312, and the multiple water distribution branch pipes 312 are all connected and communicated with the water distribution main pipe 311, and the multiple water distribution branch pipes 312 are evenly distributed on opposite sides of the water distribution main pipe 311. There are multiple nozzles 312, and multiple nozzles are arranged on one water distribution branch pipe 312. The mist dispelling water distribution assembly 32 includes a first mist dispelling pipe 321, a second mist dispelling pipe 322, a first water spraying pipe 323 and a second water spraying pipe 324. The first mist dispelling pipe 321 and the second mist dispelling pipe 322 are both connected to and communicated with the water distribution main pipe 311, and the first mist dispelling pipe 321 and the second mist dispelling pipe 322 are respectively arranged on opposite sides of the water distribution main pipe 311. There are multiple first water spraying pipes 323, and the multiple first water spraying pipes 323 are all connected to and communicated with the first mist dispelling pipe 321, and the multiple The first water spray pipes 323 are all located at the bottom of the first mist dispelling pipe 321, and there are multiple second water spray pipes 324. The multiple second water spray pipes 324 are all connected and communicated with the second mist dispelling pipe 322, and the multiple second water spray pipes 324 are all located at the bottom of the second mist dispelling pipe 322, wherein the first water spray pipe 323 and the second water spray pipe 324 are arranged in half, and the first water spray pipe 323 and the second water spray pipe 324 are both provided with multiple through holes 320, and the through holes 320 correspond to the mounting groove 213.

[0034] Furthermore, the water distribution main pipe 311 includes a first water distribution main pipe 3111 and a second water distribution main pipe 3112. The first water distribution main pipe 3111 and the second water distribution main pipe 3112 are connected by a flange. Half of the water distribution branch pipes 312 are connected and communicated with the first water distribution main pipe 3111, and the other half of the water distribution branch pipes 312 are connected and communicated with the second water distribution main pipe 3112. A first valve 313 is provided on the first water distribution main pipe 3111, and a second valve 314 is provided on the second water distribution main pipe 3112. The first valve 313 controls the on / off of one half of the water distribution branch pipes 312, while the second valve 314 controls the on / off of the other half of the water distribution branch pipes 312.

[0035] Furthermore, a third valve 325 is provided on the first mist dispersing pipe 321 , and a fourth valve 326 is provided on the second mist dispersing pipe 322 , wherein the third valve 325 controls the on-off of the plurality of first water spraying pipes 323 , and the fourth valve 326 controls the on-off of the plurality of second water spraying pipes 324 .

[0036] The water distribution system 3 of the present application adds a mist-eliminating water distribution component 32 to the conventional water distribution component 31, thereby automatically switching between different operating conditions by adjusting the first valve 313, the second valve 314, the third valve 325, and the fourth valve 326. There are three operating conditions: full mist-eliminating condition, partial mist-eliminating condition, and no mist-eliminating condition.

[0037] Full fog elimination working condition

[0038] When this operating mode is in operation, the first valve 313 and the second valve 314 are closed, and the third valve 325 and the fourth valve 326 are opened, so that the liquid in the first water spray pipe 323 and the second water spray pipe 324 flows into the porous plate 4 through the through hole 320 and then enters the demisting module 2. In this way, the saturated hot and humid air flowing through the demisting module 2 can be subjected to non-contact heat exchange with the external cold air entering the bottom of the demisting module 2. The saturated hot and humid air becomes supersaturated due to the temperature reduction, and condensed water is precipitated and flows into the water collection pool under the tower, thereby achieving the purpose of water saving. The secondary saturated air that has been cooled and dehumidified is fully mixed with the heated dry cold air above the demisting module 2, and the temperature and relative humidity are significantly reduced, thereby achieving the demisting function.

[0039] Semi-fog-eliminating conditions

[0040] When this operating mode is in operation, the first valve 313 and the third valve 325 are opened, and the second valve 314 and the fourth valve 326 are closed, so that half of the area in the tower body 1 is sprayed with water by half of the water distribution branch pipes 312 on the conventional water distribution component 31, and the other half is sprayed with water by the first water spray pipe 323 on the mist elimination water distribution component 32, so that the mist elimination module 2 of the tower body 1 has half of the mist elimination function and half of the non-misting function.

[0041] No fog removal conditions

[0042] When this operating mode is in operation, the first valve 313 and the second valve 314 are opened, and the third valve 325 and the fourth valve 326 are closed. At this time, the tower body 1 only has a conventional cooling function but no mist elimination function.

[0043] The water distribution control device for a cooling tower provided by the utility model adds a mist dispelling water distribution component 32 on the basis of a conventional water distribution component 31, thereby being able to automatically switch between different operating conditions by adjusting the first valve 313, the second valve 314, the third valve 325 and the fourth valve 326. Compared with the traditional control method of arranging mist dispelling modules and installing shutters, the control method is simpler and faster.

[0044] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the scope of the present invention. The technical scope of this utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
