Description

Technical Field

[0001] This invention relates to the field of cooling water cooling technology, and in particular to a composite flow water-saving and defogging closed cooling tower. Background Technology

[0002] In many large factories, cooling towers are used to exchange heat with cooling water carrying waste heat, allowing the waste heat to dissipate into the air. The principle is to cool the cooling water carrying waste heat entering the cooling tower through direct or indirect contact with air or water, thereby lowering the temperature inside the cooling tower and ensuring the continuous recycling of cooling water. Existing devices generally cool the cooling water in the pipes by spraying cooling water, allowing the cooling water carrying waste heat to indirectly contact the cooling water, and improve heat dissipation efficiency by air cooling and expelling water vapor. However, existing devices generate a large amount of white mist during the water vapor discharge process, which affects the environment and becomes a carrier of air pollution.

[0003] Therefore, we are now developing a composite flow-saving, defogging, and closed-loop cooling tower that can perform secondary evaporation to remove fog and whitening of discharged water vapor. Summary of the Invention

[0004] In order to overcome the shortcomings of existing devices that generate a large amount of white mist during the discharge of water vapor, thereby affecting the environment and becoming a carrier of air pollution, this invention provides a composite flow-saving and defogging closed cooling tower that can perform secondary evaporation to remove mist and whitening of discharged water vapor.

[0005] The technical solution of this invention is:

[0006] A composite flow water-saving and defogging closed-loop cooling tower includes a cooling tower, a water pump, a circulating water pipe, a water storage tank, a cooling mechanism, and a defogging mechanism. The water pump is connected to the lower right side of the cooling tower, and the circulating water pipe is connected between the water pump and the upper right side of the cooling tower. A water storage tank for collecting circulating water is connected to the bottom of the cooling tower. The right side of the water storage tank is connected to and communicates with the water pump. The cooling tower is equipped with a cooling mechanism for cooling water with waste heat, and a defogging mechanism is provided on the cooling tower for defogging the steam generated during the cooling process.

[0007] To further explain, the cooling mechanism includes a spray assembly, a circulation pipe, a packing plate, and a flow guiding assembly. The top of the cooling tower is connected to a spray assembly for spraying cooling water. The spray assembly is connected to and communicates with the circulation water pipe. The left and right sides inside the cooling tower are connected to a circulation pipe for guiding cooling water with waste heat. The left and right sides at the bottom of the cooling tower are connected to a packing plate for cooling the cooling water. The top of the cooling tower is connected to three flow guiding assemblies for guiding water vapor out.

[0008] To further explain, the defogging mechanism includes a guide frame, a sliding frame, a bidirectional motor, a lead screw, a guide rod, a heating rod, and a protective net. Guide frames are connected to the front and rear sides of both the left and right sides of the cooling tower. Sliding frames are slidably connected between adjacent left and right guide frames. A bidirectional motor is connected to the left side of the cooling tower. The output shaft of the bidirectional motor is oriented front to back. Lead screws are connected to both the front and rear output shafts of the bidirectional motor. The lead screws are threadedly connected to the adjacent sliding frames. A guide rod is connected to the upper right side of the cooling tower. The guide rod is slidably connected to the sliding frame. Heating rods for defogging are connected to the top of each sliding frame. A protective net is connected to the top of each sliding frame to protect the heating rods from damage.

[0009] To further explain, it also includes a filtration mechanism, which includes a filter tube, a filter screen, a handle, and a rotating ring. The inlet of the circulation pipe is connected to a filter tube for filtration. The right side of the filter tube is slidably connected to a filter screen for filtering impurities. The top of the filter screen is connected to a handle for easy handling. The right side of the filter tube is rotatably connected to a rotating ring for sealing the filter tube.

[0010] Further explanation: It also includes a covering mechanism, which includes a covering frame, gears, fixing parts, and racks. The upper left and right sides of the cooling tower are rotatably connected to symmetrically distributed fixing parts. The left and right adjacent fixing parts are connected to L-shaped covering frames that cover the heating rods. Gears are connected to the right side of the front covering frame and the left side of the rear covering frame. Racks that can mesh with adjacent gears are connected to the left side of the front sliding frame and the right side of the rear sliding frame.

[0011] Further explanation: It also includes a limiting mechanism, which includes a first fixed frame, a limiting plate and a torsion spring. The left and right sides of the cooling tower are connected to symmetrical first fixed frames. Each first fixed frame is rotatably connected to a limiting plate for limiting and locking the cover frame. Each limiting plate and the adjacent first fixed frame are connected to symmetrical torsion springs, which are wound around the adjacent first fixed frame.

[0012] To further explain, it also includes a cleaning mechanism, which includes a second fixed frame and a cleaning component. The left and right sides of the sliding frame are connected to symmetrical second fixed frames, and the adjacent second fixed frames are slidably connected to cleaning components for cleaning the protective net.

[0013] To further explain, the spray assembly includes a mounting frame and spray pipes. The mounting frame is connected to the top of the cooling tower, and the spray pipes are connected to the mounting frame.

[0014] To further explain, the flow guiding assembly includes a flow guiding frame, a flow guiding motor, and flow guiding fan blades. Three flow guiding frames are evenly connected to the top of the cooling tower by bolts. A flow guiding motor is connected to each flow guiding frame, and a flow guiding frame is connected to the output shaft of each flow guiding motor.

[0015] To further explain, each rotating ring has toothed protrusions.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This invention uses a bidirectional motor to drive a lead screw to rotate, which in turn causes the sliding frame to bring the heating rod closer to the closing mechanism, thereby evaporating the generated water vapor again and achieving the effect of eliminating white fog. At the same time, a protective net protects the heating rod to prevent it from being damaged.

[0018] 2. This invention uses the cooperation between the filter tube and the filter screen to prevent impurities from entering the circulation pipe, thereby improving the cleanliness of the circulation pipe and preventing blockage.

[0019] 3. The present invention moves the rack by bringing the sliding frames closer together, thereby causing the gears to drive the adjacent cover frames to flip open, so that the heating rods are no longer blocked by the cover, making it easier to carry out maintenance.

Detailed Implementation

[0031] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0032] A composite flow water-saving and mist-eliminating closed-loop cooling tower, such as Figure 1 and Figure 2 As shown, it includes a cooling tower 1, a water pump 2, a circulating water pipe 3, a water storage tank 4, a cooling mechanism 5, and a defogging mechanism 6. The water pump 2 is connected to the lower right side of the cooling tower 1, and the circulating water pipe 3 is connected between the water pump 2 and the upper right side of the cooling tower 1. The water storage tank 4 is connected to the bottom of the cooling tower 1, and the right side of the water storage tank 4 is connected to and communicates with the water pump 2. The cooling mechanism 5 is provided inside the cooling tower 1, and the defogging mechanism 6 is provided on the cooling tower 1.

[0033] It should be noted that during the treatment of cooling water with waste heat, the waste heat needs to be removed so that the cooling water can return to room temperature for circulation and cooling. This device can be used to cool the cooling water with waste heat. First, the cooling water with waste heat is injected through the cooling mechanism 5. Then, the cooling mechanism 5 is used to cool the cooling water with waste heat. At the same time, the water used for cooling will enter the water storage tank 4 and be pumped into the circulating water pipe 3 by the water pump 2, thereby cooling it again and achieving the effect of circulating cooling. Meanwhile, the steam generated during cooling can be defogging by the defogging mechanism 6 to prevent excessive fogging.

[0034] like Figure 1 and Figure 3As shown, the cooling mechanism 5 includes a spray assembly 51, a circulation pipe 52, a packing plate 53, and a flow guiding assembly 54. The spray assembly 51 is connected to the top of the cooling tower 1. The spray assembly 51 includes a mounting frame and a spray pipe. The spray assembly 51 is connected to the top of the cooling tower 1 and the spray pipe is connected to the mounting frame. The spray assembly 51 is connected to and communicates with the circulation water pipe 3. The circulation pipe 52 is connected between the left and right sides inside the cooling tower 1. The circulation pipe 52 is used to guide cooling water with waste heat. The upper opening of the circulation pipe 52 is the water inlet, and the lower opening is the water outlet. The packing plate 53 is connected between the left and right sides of the lower part of the cooling tower 1. The packing plate 53 is used to cool the cooling water. Three flow guiding assemblies 54 are connected to the top of the cooling tower 1. The flow guiding assembly 54 includes a flow guiding frame, a flow guiding motor, and a flow guiding fan blade. Three flow guiding frames are evenly connected to the top of the cooling tower 1 by bolts. A flow guiding motor is connected to each flow guiding frame by bolts. A flow guiding frame is connected to the output shaft of each flow guiding motor.

[0035] It should be noted that when treating cooling water containing waste heat, cooling water can be introduced through the inlet on the upper side of the circulating pipe 52, thereby bringing the circulating pipe 52 into a high-temperature state. Then, the cooling water is sprayed through the spray assembly 51, allowing the cooling water to spray onto the circulating pipe 52, thus cooling the cooling water entering the circulating pipe 52. At this time, as the warm water comes into contact with the high-temperature circulating pipe 52, water vapor is generated. The remaining cooling water will be cooled through the packing plate 53 before entering the water storage. The water is stored in tank 4, and then pumped out of tank 4 by pump 2 for secondary circulation and cooling. During the cooling process, the generated water vapor will be discharged upward. At this time, the guide component 54 is activated to guide the water vapor upward, completing the overall cooling process. In summary, the cooling water is sprayed by the spray component 51, so that the cooling water comes into contact with the cooling water with waste heat entering the circulation pipe 52, and the cooling water in the circulation pipe 52 is cooled, thereby achieving the cooling effect.

[0036] like Figure 1 , Figure 4 and Figure 5As shown, the defogging mechanism 6 includes a guide frame 61, a sliding frame 62, a bidirectional motor 63, a lead screw 64, a guide rod 65, a heating rod 66, and a protective net 67. The front and rear sides of the left and right sides of the cooling tower 1 are connected to the guide frame 61, and the two adjacent guide frames 61 are slidably connected to each other by a sliding frame 62. The left side of the cooling tower 1 is connected to the bidirectional motor 63 by bolts. The front and rear output shafts of the bidirectional motor 63 are connected to the lead screw 64, and the lead screw 64 is threadedly connected to the adjacent sliding frame 62. The upper right side of the cooling tower 1 is connected to the guide rod 65, and the guide rod 65 is slidably connected to the sliding frame 62. The top of the sliding frame 62 is connected to the heating rod 66, and the top of the sliding frame 62 is connected to the protective net 67.

[0037] It should be noted that during the treatment of cooling water containing waste heat, a large amount of water vapor is generated. This water vapor is discharged as white smoke through the guide assembly 54. To eliminate the fog, the output shafts of the bidirectional motor 63 drive the lead screw 64 to rotate, causing the sliding frame 62 to close together under the action of adjacent guide frames 61 and guide rods 65. As the water vapor is discharged upwards, it undergoes secondary evaporation under the action of the heating rod 66, thus achieving the effect of eliminating white fog. Simultaneously, the heating rod 66 is protected by the protective net 67 to prevent damage. In summary, the bidirectional motor 63 drives the lead screw 64 to rotate, causing the sliding frame 62 to bring the heating rod 66 closer together and close, further evaporating the generated water vapor to achieve the effect of eliminating white fog. The protective net 67 also protects the heating rod 66 from damage.

[0038] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a filtration mechanism 7, which includes a filter pipe 71, a filter screen 72, a handle 73, and a rotating ring 74. The filter pipe 71 is connected to the inlet of the circulation pipe 52. The filter screen 72 is slidably connected to the right side of the filter pipe 71. The top of the filter screen 72 is connected to a handle 73. The right side of the filter pipe 71 is rotatably connected to a rotating ring 74. The rotating ring 74 is equipped with toothed protrusions to facilitate rotation by the operator.

[0039] It should be noted that, to prevent the cooling water containing waste heat from entering the circulation pipe 52 and causing blockage, the filter pipe 71 and filter screen 72 can be coordinated to prevent debris from entering the circulation pipe 52. When the filter screen 72 needs to be replaced, the rotating ring 74 is rotated to expose the handle 73. The filter screen 72 can then be removed through the handle 73 for replacement or cleaning. After cleaning, the filter screen 72 is returned to its original position, and the rotating ring 74 is rotated in the opposite direction to cover the handle 73. In summary, by coordinating the filter pipe 71 and filter screen 72, debris is prevented from entering the circulation pipe 52, improving the cleanliness of the circulation pipe 52 and preventing blockage.

[0040] like Figure 1 and Figure 8 As shown, it also includes a covering mechanism 8, which includes a covering frame 81, gears 82, fixing members 83 and racks 84. Fixing members 83 are symmetrically distributed front and back and rotatably connected between the left and right sides of the upper part of the cooling tower 1. A covering frame 81 is connected between adjacent left and right fixing members 83. The covering frame 81 has an L-shaped structure and is used to cover the heating rod 66. Gears 82 are connected to the right side of the front covering frame 81 and the left side of the rear covering frame 81. A rack 84 is connected to the left side of the front sliding frame 62 and the right side of the rear sliding frame 62. The rack 84 can mesh with the adjacent gears 82.

[0041] It should be noted that as the sliding frames 62 move closer to each other, they will drive the corresponding racks 84 to move, which in turn will drive the adjacent gears 82 to rotate. At this time, the gears 82 will drive the adjacent cover frames 81 to rotate and unfold to the side away from each other, so that the cover frames 81 no longer block the adjacent heating rods 66. If the heating rods 66 are damaged, they can be repaired. In summary, by moving the sliding frames 62 closer to each other, the racks 84 move, which in turn causes the gears 82 to drive the adjacent cover frames 81 to flip and open, so that the heating rods 66 are no longer blocked by the cover, making it easier to carry out maintenance.

[0042] like Figure 1 and Figure 9 As shown, it also includes a limiting mechanism 9, which includes a first fixed frame 91, a limiting plate 92 and a torsion spring 93. The left and right sides of the cooling tower 1 are connected to the front and rear symmetrical first fixed frames 91 by bolts. The first fixed frames 91 are rotatably connected to the limiting plates 92. The limiting plates 92 are used to limit and lock the cover frame 81. The limiting plates 92 and the adjacent first fixed frames 91 are connected to the upper and lower symmetrical torsion springs 93.

[0043] It should be noted that after the cover frame 81 is flipped open to the side away from each other, in order to prevent the cover frame 81 from shaking, the limiting plates 92 can be flipped to the side away from the cover frame 81, so that the corresponding torsion springs 93 are deformed by force. Then, as the cover frame 81 is flipped, the limiting plates 92 are released. Under the action of the torsion springs 93, the limiting plates 92 will rotate back to the side closer to the cover frame 81 and lock the cover frame 81 to prevent it from shaking. In summary, through the cooperation between the limiting plates 92 and the torsion springs 93, the flipped cover frame 81 is locked and limited to prevent it from shaking.

[0044] like Figure 1 and Figure 10 As shown, it also includes a cleaning mechanism 10, which includes a second fixed frame 101 and a cleaning component 102. The left and right sides of the sliding frame 62 are connected to the front and rear symmetrical second fixed frames 101, and the front and rear adjacent second fixed frames 101 are slidably connected to the cleaning component 102.

[0045] It should be noted that, in order to avoid excessive impurities on the protective net 67, which would affect the efficiency of water vapor discharge, the protective net 67 can be cleaned periodically by sliding the cleaning component 102.

[0046] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
