[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figures 1 to 3 The utility model discloses a mechanical ventilation open cooling tower, comprising: a wet hot water vapor filter plate 11, the wet hot water vapor filter plate 11 is arranged at the air inlet end of an exhaust assembly, the exhaust assembly is fixed on the top of a cooling tower shell 6, and a water cooling system is arranged in the cooling tower shell 6.

[0025] When in use, the water cooling system arranged in the cooling tower shell 6 is used for hot water cooling. When the water cooling system is used for hot water cooling, some residual high-temperature steam will enter the exhaust component. By setting a wet hot water steam filter plate 11 at the air inlet end of the exhaust component, this part of the residual high-temperature steam can be absorbed, thereby effectively avoiding the high-temperature steam from damaging the exhaust component, thereby extending the service life of the equipment.

[0026] A further optimized solution is that the hot and wet steam filter plate 11 includes a plate body 1101, on which a plurality of air holes 1102 are provided in a matrix, a plurality of drip blocks 1104 arranged in a matrix are fixedly connected to the bottom of the plate body 1101, and a plurality of heat dissipation blocks 1103 arranged in a matrix are fixedly connected to the top of the plate body 1101.

[0027] The board body 1101, the heat sink 1103 and the drip block 1104 are all made of metal materials with good thermal conductivity. The high-temperature steam needs to pass through the air vent 1102 to enter the air inlet end of the exhaust assembly. The heat sink 1103 dissipates heat to the board body 1101 and the drip blocks 1104. When the high-temperature steam contacts the board body 1101 and the drip blocks 1104 at the bottom of the board body 1101, due to the temperature difference, the wet hot water steam condenses into water droplets on the surface of the board body 1101 and the drip blocks 1104, and the water droplets are collected and dripped under the action of the drip blocks 1104, thereby preventing a large amount of water vapor from entering the exhaust assembly.

[0028] To further optimize the solution, a water-absorbing material box 14 is also provided at the air inlet end of the exhaust component. The water-absorbing material box 14 is fixed in the cooling tower shell 6. A number of air holes are opened on the side wall of the water-absorbing material box 14. The water-absorbing material box 14 is filled with water-absorbing material. The humid hot water vapor passes through the humid hot water vapor filter plate 11 and the water-absorbing material box 14 in turn and then enters the exhaust component.

[0029] In order to further improve the water vapor absorption effect, a water absorbing material box 14 is also provided at the front end of the air inlet end of the exhaust assembly. After the water vapor is partially removed by the wet hot water vapor filter plate 11, it enters the water absorbing material box 14 and is absorbed by the water absorbing material, which can further reduce the water vapor content entering the exhaust assembly. The water absorbing material is preferably water absorbing silica gel.

[0030] According to a further optimized solution, the exhaust assembly includes an exhaust fan bracket 12 , the exhaust fan 3 is rotatably connected to the middle of the exhaust fan bracket 12 , the output shaft of the motor 13 is connected to the shaft of the exhaust fan 3 , and the fixed end of the motor 13 is fixedly connected to the exhaust fan bracket 12 .

[0031] Further optimized solution, the water cooling system includes a plurality of water inlet pipes 9 arranged in sequence, the plurality of water inlet pipes 9 are located on the same horizontal plane, the water inlet pipes 9 are connected to a plurality of nozzles 10, the plurality of nozzles 10 are arranged at equal intervals along the length direction of the water inlet pipes 9, the water inlet pipes 9 are fixedly connected to the middle of the cooling tower shell 6, and the wet hot water vapor filter plate 11 is located above the plurality of water inlet pipes 9;

[0032] A water spray filler 8 is provided below a plurality of water inlet pipes 9, and the water spray filler 8 is fixed on a cooling tower shell 6. A collecting pool 1 is provided below the water inlet pipes 9, and a drain pipe 2 is connected to the bottom of the collecting pool 1;

[0033] An air intake assembly is provided on the cooling tower shell 6 .

[0034] A further optimized solution is that the air intake assembly includes a first air intake part and a second air intake part, the first air intake part includes a plurality of air intake filters 4, the air intake filters 4 are embedded in the side wall of the cooling tower shell 6, the interior of the cooling tower shell 6 is connected to the atmosphere through the air intake filters 4, and the air intake filters 4 are located below the water spray filler 8.

[0035] To further optimize the solution, the second air inlet part includes a plurality of air inlet pipes 7, which are fixed to the top side wall of the cooling tower shell 6, and the air outlet end of the air inlet pipe 7 is located on one side of the heat sink 1103; the air inlet end of the air inlet pipe 7 is located at the bottom of the cooling tower shell 6.

[0036] When in use, hot water is sprayed onto the water sprinkling filler 8 through a plurality of water inlet pipes 9 and a plurality of nozzles 10, so that the hot water forms a mist and contacts the water sprinkling filler 8. Under the action of the exhaust fan 3, air enters through a plurality of air inlet filters 4 at the bottom to dissipate the heat of the water sprinkling filler 8, and then blows the heat toward the plate body 1101. The air inlet filter 4 can filter dust in the air to prevent pollution to the interior of the cooling tower shell 6.

[0037] The water drops after the heat dissipation fall into the collection tank 1 and are discharged through the drain pipe 2.

[0038] The air inlet pipe 7 arranged on the side wall of the cooling tower shell 6 sucks the cold air at the bottom to one side of the heat dissipation block 1103, and blows it directly to a number of heat dissipation blocks 1103, and then the heat on the heat dissipation block 1103 is taken out by the exhaust fan 3, thereby ensuring that the overall temperature of the wet hot water vapor filter plate 11 is lower than the temperature of the high-temperature hot water vapor, ensuring that the water vapor can condense.

[0039] According to a further optimized solution, a plurality of inspection port covers 5 are embedded in the side wall of the cooling tower shell 6 , and the inspection port covers 5 are located above the air inlet filter 4 .

[0040] The inspection port cover plate 5 is fixed to the side wall of the cooling tower shell 6 by screws. The inspection port cover plate 5 can be easily disassembled by removing the screws, thereby facilitating maintenance.
