Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a demisting cooling tower. Background Technology

[0002] The basic principle of a cooling tower is to spray hot water onto the packing material, achieving cooling through heat exchange between the hot water and the air. During the cooling process, mist is formed. Most existing demisting cooling towers use static condensation demisting, which can achieve the demisting effect when there is little mist inside. However, when more mist is generated inside, the amount of mist escaping also increases. The escaped mist cannot be kept at a low concentration, and the escaped mist has a certain negative impact on the surrounding environment. Summary of the Invention

[0003] This invention addresses the problem in demisting cooling towers where increased internal mist generation leads to a corresponding increase in escaping mist, making it difficult to maintain a low concentration of escaping mist. By incorporating a dynamic demisting device and spray pipes, this invention promptly eliminates mist escaping from the condensation module when the internal mist concentration is high, thus keeping the mist level within a low range and better protecting the surrounding atmospheric environment. When the internal mist concentration is low, the dynamic demisting device and spray pipes cease operation, conserving water resources.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A demisting cooling tower includes a tower body, a water storage tank at the bottom of the tower body, and a fan at the top of the tower body. Louvers are installed on the sides of the tower body. Packing material is installed above the water storage tank. An inlet pipe, a water collector, and a condensation module are sequentially installed above the packing material. Spray nozzles are installed on the inlet pipe. A dynamic demisting device is installed at the top of the tower body. A spray pipe is installed between the dynamic demisting device and the condensation module. The dynamic demisting device includes a condensation plate, which is movably mounted on both sides of the air outlet at the top of the tower body. When the mist concentration in the tower body is high, the dynamic demisting device and the spray pipes activate to remove the escaping mist and maintain the mist concentration at a low level.

[0006] Preferably, the dynamic demisting device consists of two sets, respectively installed on both sides of the air outlet at the top of the tower. A cylinder is installed on the outside of the tower, and the condensing plate is connected to the cylinder. The cylinder pushes the condensing plate to move horizontally.

[0007] Preferably, a support plate is provided below the condenser plate, and a slide rod is embedded in the support plate. The slide rod protrudes from the support plate. A rack is provided on the side of the condenser plate. A valve is provided on the spray pipe. A gear is coaxially welded to the upper part of the valve. The gear and the rack are connected by a gear engagement. The horizontal movement of the condenser plate drives the gear and the valve on the spray pipe to rotate coaxially, thereby controlling the spray pipe.

[0008] Preferably, the spray pipe is connected to the water storage tank at the bottom, a water pump is installed at the connection point, and a spray head is installed on the spray pipe. The water pump draws the cooled water from the water storage tank to the top of the condensation module to spray the mist escaping from the condensation module, thereby achieving the effect of condensation and demisting.

[0009] Preferably, the condensation module includes a condensation block and a slide rail. The condensation block is provided with pulleys that match the slide rail. Baffles are provided at both ends of the slide rail. The longitudinal section of the condensation block is rhomboid. The pulleys are located at the upper and lower ends of the condensation block and match the slide rail. The baffles are located on the outside of the tower body. The height of the baffles is the same as the height of the condensation module. The baffles are detachably connected to the tower body. The condensation block can be replaced by removing the baffles to maintain the demisting quality.

[0010] Preferably, the water collector is wavy and includes a raised vent portion and a recessed water tank portion. The vent portion is uniformly provided with a mesh, and the water tank portion is for convenient storage of condensate after contact with the condensation module. The vent portion is provided to allow mist to pass through and contact the condensation block. The mist can condense first by passing through the mesh and then condense again by contacting the condensation module, thereby improving the demisting effect.

[0011] Preferably, the height of the louvers is located between the water storage tank and the packing material, and the louvers are set with the inner side higher than the outer side, so that external air can be easily drawn into the tower body from the outside, while the mist inside the tower body is not easily discharged through the louvers and pollutes the environment.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] This invention features a dynamic demisting device installed at the top of the tower. When the mist concentration inside the tower is high, the dynamic demisting device activates, using a condenser plate for further condensation and demisting to reduce the mist concentration. A spray pipe is installed below the dynamic demisting device. When the dynamic demisting device is activated, a rack on the condenser plate drives a gear and valve to rotate coaxially, opening the spray head to spray and condense the mist inside the tower, achieving a demisting effect. The combined operation of the dynamic demisting device and the spray pipe maintains a low mist concentration inside the tower, preventing negative impacts on the surrounding environment. When the mist concentration inside the tower is low, the dynamic demisting device and the spray pipe stop working, conserving water resources. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1-5 As shown, this embodiment provides a demisting cooling tower, including a tower body 1, a water storage tank 7 located at the bottom of the tower body 1, and a fan 2 located at the air outlet at the top of the tower body 1. Louvers 3 are provided on the side of the tower body 1. Packing material 4 is provided above the water storage tank 7. A water inlet pipe 6, a water collector 8, and a condensation module 9 are sequentially arranged above the packing material 4. Spray nozzles 5 are provided on the water inlet pipe 6.

[0022] A dynamic demisting device 10 is installed at the top of the tower body 1. A spray pipe 11 is installed between the dynamic demisting device 10 and the condensation module 9. The dynamic demisting device 10 includes a condensation plate 102, which is movably installed on both sides of the air outlet at the top of the tower body 1. There are two sets of dynamic demisting devices 10, which are respectively installed on both sides of the air outlet at the top of the tower body 1. A cylinder 101 is installed on the outside of the tower body 1. The condensation plate 102 is connected to the cylinder 101. A support plate 104 is installed below the condensation plate 102. A sliding rod 105 is embedded in the support plate 104. 5 protrudes from the support plate 104. A rack 106 is provided on the side of the condensing plate 102. A valve 114 is provided on the spray pipe 11. A gear 115 is coaxially fixedly welded to the upper part of the valve 114. The gear 115 and the rack 106 are connected by a gear engagement. When there is a lot of mist in the tower body 1, the cylinder 101 pushes the condensing plate 102 to move horizontally. The two sets of condensing plates 102 move closer to the center of the tower body. After closing, the mist condenses on the condensing plate 102, achieving the demisting effect. When there is not much mist in the tower body 1, the cylinder 101 drives the condensing plate 102 back to the initial position.

[0023] The spray pipe 11 is connected to the water storage tank 7 at the bottom. A water pump 111 is installed at the connection. A spray head 113 is installed on the spray pipe 11. The water in the water storage tank 7 is condensed water with a low temperature, which can be used as spray water to condense the mist. The water pump 111 is used to pump the water in the water storage tank 7 to the top of the condensation module 9 and spray it through the spray head 113.

[0024] When there is a lot of mist inside the tower body 1, the dynamic demisting device 10 starts to work. During the movement of the condensing plate 102, the rack 106 set on the side of the condensing plate 102 drives the gear 115 and the valve 114 to rotate coaxially, thereby opening the valve 114 and starting the spray pipe 11 to work, achieving the spray demisting effect. When there is not much mist inside the tower body 1, the cylinder 101 drives the condensing plate 102 back to the initial position. During the return process, the rack 106 set on the side of the condensing plate 102 closes the valve 114, causing the spray pipe 11 to stop working, thus saving water resources.

[0025] The condensation module 9 includes a condensation block 91 with pulleys 911, a slide rail 93 above the water collector 8, and baffles 92 at both ends of the slide rail 93. The condensation block 91 is rhomboid in shape. The pulleys 911 are respectively located at the upper and lower ends of the condensation block 91 and match the slide rail 93. The pulleys 911 at both ends of the condensation block 91 are provided to better stabilize the condensation block 91 on the slide rail 93. The height of the baffles 92 is the same as the height of the condensation module 9. The baffles 92 are detachably connected to the outside of the tower body 1. Specifically, the tower body 1 has a maintenance hole corresponding to the position of the condensation module 9, and a baffle 92 is provided at the maintenance hole. The baffles 92 are threadedly connected to the tower body 1. When the condenser block 91 needs to be replaced, the baffles 92 at both ends can be removed, and the condenser block 91 with pulley 911 can be placed into the tower body 1 along the slide rail 93 through the maintenance hole. The new condenser block 91 placed in from one maintenance hole pushes the old condenser block 91 out from the other maintenance hole, thereby achieving the purpose of replacing the condenser block 91 and maintaining the demisting quality.

[0026] The water collector 8 is wavy and includes a raised vent portion 81 and a recessed water tank portion 82. A mesh 811, which can be a copper wire mesh, is evenly arranged in the vent portion 81. The water tank portion 82 of the water collector 8 is for convenient storage of condensate after contact with the condensation module 9. The vent portion 81 is provided to allow mist to pass through and contact the condensation block 91. The mist can condense first through the mesh 811 and then condense again in contact with the condensation module 9, thereby improving the demisting effect.

[0027] The height of the louver 3 is located between the water storage tank 7 and the packing 4. The louvers of the louver 3 are set to be higher on the inside and lower on the outside, so that the outside air can be easily drawn into the inside of the tower body 1 from the outside, while the mist inside the tower body 1 cannot easily flow out of the outside of the tower body 1 through the louver 3 and cause environmental pollution.

[0028] The specific working method of this utility model is as follows:

[0029] When the mist concentration inside tower 1 is high, the condensation module 9 is insufficient to maintain the mist at a low concentration level, and some mist will escape, negatively impacting the surrounding environment. At this time, the dynamic demisting device 10 and spray pipe 11 start working. The cylinder 101 pushes the condensation plate 102 to move horizontally, causing the two sets of condensation plates 102 to close. The mist condenses and falls on the condensation plates 102, achieving the effect of condensation and demisting. At the same time, when the condensation plates 102 close, the rack 106 set on the side of the condensation plate 102 moves, thereby driving the gear 11. 5 and valve 114 rotate coaxially, thereby opening valve 114 and causing spray pipe 11 to start working. Water pump 111 draws water with low temperature from water storage tank 7 to the top of condensing module 9 to spray and condense the mist, achieving the effect of spraying and demisting. When the mist concentration inside tower body 1 is not high, cylinder 101 drives condensing plate 102 back to the initial position. During the reset process, valve 114 is closed by rack 106 located on condensing plate 102, thereby achieving the effect of saving water resources and realizing the purpose of utilizing water resources while demisting.

[0030] When the condenser block 91 has been used for a long time, open the baffle 92 and put the condenser block 91 with pulley 911 into the tower body 1 along the slide rail 93. The new condenser block 91 put in from one side pushes the old condenser block 91 out from the other side, thus completing the replacement of the condenser block 91 and maintaining the demisting quality.

Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
