Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange, in particular to an energy-saving and mist-eliminating evaporative air cooler. Background Art

[0002] Heat exchange refers to the transfer of heat between hot and cold fluids. The most commonly used heat carriers are steam, water and air. Steam heat exchange is one of the most common heat exchange methods.

[0003] The current steam heat exchanger sets the condensing module above the air inlet window, and the spray system is set above the condensing module. The sprayed water exchanges heat with the hot steam in the condensing module, and then the fan exchanges heat with the drawn air and water. The air inlet window is set below the condensing module. When the fan draws air, most of the wind force is blocked by the condensing module, affecting the heat exchange with the water, resulting in little change in water temperature, affecting the heat exchange effect. The air present in the condensing module will also lead to low heat exchange efficiency, resulting in energy waste, and a large amount of white mist is generated during the heat exchange process, which has an adverse impact on the environment. Summary of the Invention

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an energy-saving and mist-eliminating evaporative air cooler, comprising a shell, wherein a condensing module, a water sprinkling filler and a spraying system are arranged inside the shell from bottom to top, a fan is arranged on the top of the shell, and air inlet windows are symmetrically arranged on both sides of the shell, and the air inlet windows are located between the condensing module and the water sprinkling filler, a spray water tank is arranged at the bottom of the shell, and the spray water tank is connected to the spray system through a spray water pump, and a fin tube vacuum tube bundle is arranged above the spray system for extracting air from the condensing module.

[0006] As an optimal technical solution of the present invention, the condensation module includes a steam inlet, a steam inlet pipe box, a steam pipeline, a condensate outlet and a condensate pipe box. The steam inlet and the steam inlet pipe box are arranged at one end of the steam pipeline, the condensate pipe box is arranged at the other end of the steam pipeline, the condensate outlet is arranged at the lower end of the condensate pipe box, and the upper end of the condensate pipe box is connected to the fin tube vacuum tube bundle through a pipeline.

[0007] As a preferred technical solution of the present invention, the steam pipeline is arranged to be inclined downward.

[0008] As an optimal technical solution of the present invention, the fin tube vacuum tube bundle includes a vacuum front tube box, a vacuum rear tube box, a vacuum tube, an air inlet pipe and a water receiving pipe. The vacuum front tube box and the vacuum rear tube box are respectively arranged at both ends of the vacuum tube. One end of the vacuum front tube box is connected to the vacuum pump through a pipeline, the upper side of one end of the vacuum rear tube box is connected to the upper end of the condensate pipe box through the air inlet pipe, the lower side of one end of the vacuum rear tube box is connected to the water receiving pipe, the water receiving pipe is connected to the inlet of the external water tank, and the outer side of the vacuum tube is evenly covered with fins.

[0009] As a preferred technical solution of the present invention, the vacuum tube is arranged obliquely downward.

[0010] As an optimal technical solution of the present utility model, the spray system includes a spray water valve, a water inlet pipe, a water collecting tank, a spray water pipe and a nozzle. The spray water pipe is arranged above the water filling material, and the nozzles are evenly distributed at the lower end of the spray water pipe.

[0011] As a preferred technical solution of the present invention, a water collector is provided between the spray system and the finned tube vacuum tube bundle.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the energy-saving and demisting evaporative air cooler is reasonably designed and ingeniously conceived. By arranging the condensing module below the air inlet window, the cold air and water are fully exchanged for heat when the fan is exhausting air, so that the water temperature drops and exchanges heat with the steam in the condensing module, thereby improving the heat exchange efficiency. At the same time, a finned tube vacuum tube bundle is arranged to extract the air in the condensing module, thereby improving the heat exchange efficiency and saving energy. The finned tube vacuum tube bundle exchanges heat with the humid hot air again, so that part of the humid hot air is condensed into water droplets and part becomes dry hot air, and white mist cannot be formed. The water generated after heat exchange in the finned tube vacuum tube bundle can be reused, thereby further saving energy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiment of the present invention to clearly and completely describe the technical solutions in the embodiment of the present invention.

[0016] See also Figure 1 The utility model provides a technical solution: an energy-saving and mist-eliminating evaporative air cooler, comprising a shell 10, wherein a condensing module 7, a water sprinkling filler 5 and a spraying system 4 are arranged inside the shell 10 from bottom to top, a fan 1 is arranged on the top of the shell 10, and air inlet windows 6 are symmetrically arranged on both sides of the shell 10, and the air inlet windows 6 are located between the condensing module 7 and the water sprinkling filler 5, a spraying water tank 8 is arranged at the bottom of the shell 10, and the spraying water tank 8 is connected to the spraying system 4 through a spraying water pump 9, and the spraying system 4 includes a spraying water valve 41, a water inlet pipe 42, a water collecting tank 43, a spraying water pipe 44 and a nozzle 45, the spraying water pipe 44 is arranged above the water sprinkling filler 5, and the nozzles 45 are evenly distributed at the lower end of the spraying water pipe 44, one end of the spraying water pipe 44 is connected to the water collecting tank 43, and one end of the water collecting tank 43 is connected to the spraying water pump 9 through the water inlet pipe 42, and a spraying water valve 41 is provided on the water inlet pipe 42;

[0017] A finned tube vacuum tube bundle 2 is provided above the spray system 4 for extracting the air in the condensing module 7. The finned tube vacuum tube bundle 2 includes a front vacuum tube box 21, a rear vacuum tube box 22, a vacuum tube 23, an air inlet pipe 25 and a water collecting pipe 24. The front vacuum tube box 21 and the rear vacuum tube box 22 are respectively provided at both ends of the vacuum tube 23. One end of the front vacuum tube box 21 is connected to the vacuum pump through a pipeline, and the upper side of one end of the rear vacuum tube box 22 is connected to the air inlet pipe 25. 5 is connected to the upper end of the condensate pipe box 74. After vacuuming, the lower side of one end of the pipe box 22 is connected to the water collecting pipe 24, and the water collecting pipe 24 is connected to the inlet of the external water tank. The outer side of the vacuum tube 23 is evenly covered with fins. The air in the condensation module 7 is extracted by the vacuum pump to ensure sufficient heat exchange between steam and water, thereby improving the heat exchange efficiency. At the same time, the fins on the vacuum tube 23 exchange heat with part of the hot and humid air and turn into water droplets. The other part of the hot and humid air is mixed with the cold air and turns into dry hot air, so that white mist cannot be formed.

[0018] The condensation module 7 includes a steam inlet 71, a steam inlet pipe box 72, a steam pipeline 75, a condensate outlet 73 and a condensate pipe box 74. The steam inlet 71 and the steam inlet pipe box 72 are arranged at one end of the steam pipeline 75, the condensate pipe box 74 is arranged at the other end of the steam pipeline 75, the condensate outlet 73 is arranged at the lower end of the condensate pipe box 74, and the upper end of the condensate pipe box 74 is connected to the fin tube vacuum tube bundle 2 through a pipeline. During the heat exchange process, the water condensed from the steam flows out from the condensate outlet 73 and can be collected and utilized.

[0019] Furthermore, in order to facilitate the rapid outflow of condensed water and prevent it from accumulating in the steam pipe 75, the steam pipe 75 is arranged to be inclined downward.

[0020] Furthermore, in order to facilitate the recovery of partially condensed water droplets after heat exchange in the vacuum tube 23 , the vacuum tube 23 is arranged to be tilted downward.

[0021] Furthermore, in order to conveniently collect water generated after heat exchange between the moist hot air and the fin tube vacuum tube bundle 2 , a water collector 3 is provided between the spray system 4 and the fin tube vacuum tube bundle 2 .

[0022] During use: the water sprayed from the nozzle 45 in the spray system 4 passes through the water spraying filler 5 and falls on the steam pipe 75 to exchange heat with the steam. Finally, the water flows in the spray water tank 8 at the bottom and is pumped to the spray system 4 through the spray water pump 9 to realize the recycling of the spray water; the spray water forms humid hot air after heat exchange with the steam pipe 75. Under the action of the fan 1, cold air enters from the air inlet window 6 and is drawn upward. The cold air exchanges heat with the spray water after heat exchange, so that the water temperature is reduced to ensure the heat exchange effect. At the same time, the cold air mixes with a part of the humid hot air to form dry hot air and is discharged. The other part of the humid hot air exchanges heat with the fins on the outside of the vacuum tube 23 to form water droplets, which are recovered by the water collector 3 and cannot form white mist. The vacuum tube 23 draws out the air in the steam pipe 75 to improve the heat exchange efficiency.

[0023] The utility model improves the heat exchange efficiency and saves energy by increasing the heat exchange area between cold air and water and extracting the air in the steam pipeline 75, while eliminating white mist and not affecting the environment.
