[0002] In a combined air conditioning system, the humidifier is an extremely important part. As long as there is a requirement for environmental humidity, the control and adjustment of the humidifier is required.

[0003] In the design and use of modular air conditioners, traditional opposed-type high-pressure spray humidifiers (with two nozzles facing windward and leeward, respectively) provide a significant humidification capacity, particularly in southern China, where humidity is consistently high. Given the same air volume, the required humidification capacity is significantly lower than in northern China. However, if other humidification methods, such as two-fluid humidification and mist humidification, are used in fresh air air conditioning systems, where humidification requirements are moderate, as in southern China, the humidification capacity provided is significantly insufficient.

[0004] Therefore, how to solve the above-mentioned deficiencies in the prior art has become the subject to be studied and solved in this utility model. Utility Model Content

[0005] The purpose of the utility model is to provide a double-flow vaporization humidifier.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A dual-flow vaporizing humidifier comprises a humidifier liner arranged in an air inlet channel and at least one spray humidification system and at least one wet film humidification system arranged in the humidifier liner;

[0008] The spray humidification system and the wet film humidification system are alternately distributed along the air inlet direction, wherein the wet film humidification system is located on the air outlet side;

[0009] The spraying direction of the spray humidification system is perpendicular to the air inlet direction.

[0010] In a further solution, the humidifier inner tank includes a water tank and a bellows detachably connected to the water tank, with an air inlet and an air outlet on both sides of the bellows respectively, and the bottom of the bellows is open and connected to the water tank.

[0011] In a further solution, a card plate is provided in the water tank, and an installation card slot corresponding to the wet film humidification system is formed between the card plate and the water tank wall, and the wet film humidification system is clipped into the installation card slot.

[0012] In a further solution, the wet film humidification system includes at least one wet film humidifier distributed along the air inlet direction, and the wet film humidifier includes a door-type frame, a water distributor, a wet film and an electric heater. The water distributor and the wet film are distributed up and down in the door-type frame, and the electric heater is arranged on the door-type frame. The bottom of the door-type frame is engaged with the mounting slot, and the two sides and the top outer wall of the door-type frame are fit-connected with the inner wall of the wind box.

[0013] In a further solution, the spray humidification system includes at least one spray humidifier distributed along the air inlet direction, the spray humidifier includes a spray pipe and nozzles arranged in pairs on the spray pipe, and the paired nozzles are symmetrically arranged and perpendicular to the air inlet direction.

[0014] In a further solution, the water distributor and the sprinkler pipe are jointly connected to an external water supply system.

[0015] In a further solution, the external water supply system includes a pump station and a circulation pipeline connected to the pump station, the water inlet pipeline of the circulation pipeline is connected to the water tank, the water outlet pipeline is connected to the sprinkler pipe and the water distributor, and a valve is provided on the water outlet pipeline connected to the water distributor.

[0016] In a further solution, the external water supply system further includes a filter, and the filter is arranged on the water inlet pipe and the water outlet pipe of the circulation pipe.

[0017] In a further solution, the external water supply system also includes a water supply pipe, one end of which is connected to the water tank, and the other end is connected to an external water source through a water pump. A liquid level gauge is provided in the water tank, and the liquid level gauge and the water pump are both connected to a controller.

[0018] In a further solution, the external water supply system further includes an overflow drain pipe connected to the water tank, and an overflow valve is provided on the overflow drain pipe.

[0019] The working principle and advantages of this utility model are as follows:

[0020] The utility model combines a spray pipe with a wet film and sets the spray direction to be perpendicular to the wind direction, which can realize a dual-process humidification process of atomization humidification followed by evaporation humidification. It is suitable for applications with moderate humidification requirements. While ensuring the provision of a stable humidification amount, it will not generate unnecessary energy waste, reducing the energy consumption of the unit, and has obvious advantages of energy saving and environmental protection.

At the same time, it can also reduce production costs and operating costs and increase profits under the same requirements.

[0021] The utility model utilizes the wet film to capture and block the water mist generated by the spraying, and utilizes the captured water mist for further humidification while also avoiding waste caused by diffusion of the water mist, thus killing two birds with one stone and saving the cost of the front and rear baffle structures provided in the spray-type spray humidifier for blocking the diffusion of the water mist.

[0022] The utility model forms a clamping groove by arranging a clamping plate in the water tank. The formed clamping groove can be used to clamp and fix the wet film and used as a water receiving tray for the wet film, which is convenient for installation and saves the cost of the water receiving tray at the bottom of the wet film, thus killing two birds with one stone.

[0023] When there is no external water supply, the wet membrane of the utility model utilizes the captured spray water mist to evaporate and humidify the incoming air, which is suitable for use in situations where the humidification demand is low; when there is an external water supply, the wet membrane utilizes the captured spray water mist and the external water supply to evaporate and humidify the incoming air, which is suitable for use in situations where the humidification demand is high; both schemes can be realized through valve control, which is simple to operate, flexible and practical.

Example

[0043] See attached Figure 1-5 A dual-flow vaporizing humidifier includes a humidifier liner 1 arranged in an air inlet channel and a spray humidification system and a wet film humidification system arranged in the humidifier liner 1.

[0044] In this embodiment, the spray humidification system and the wet film humidification system are alternately distributed along the air inlet direction, wherein the wet film humidification system is located on the air outlet side, and the spray humidification system is arranged in the middle position between the air outlet side and the air inlet side to ensure that the spray humidification system is not too close to the wet film humidification system, affecting the humidification effect of the wet film 23.

[0045] In this embodiment, the humidifier inner tank 1 includes a water tank 11 and a bellows 12 detachably connected to the water tank 11, and the bellows 12 has an air inlet and an air outlet on both sides respectively. The bottom of the bellows 12 is open and connected to the water tank 11; the water mist generated by the spray humidification system and the wet film humidification system can be collected and recovered in the water tank 11 for recycling.

[0046] In this embodiment, a clamping plate 13 is provided in the water tank 11 , and an installation clamping slot 14 corresponding to the wet film humidification system is formed between the clamping plate 13 and the wall of the water tank 11 . The wet film humidification system is clamped in the installation clamping slot 14 .

[0047] The wet film humidification system includes a wet film humidifier 2 distributed along the air inlet direction, and the wet film humidifier 2 includes a door frame 21, a water distributor 22, a wet film 23 and an electric heater 24. The water distributor 22 and the wet film 23 are distributed up and down in the door frame 21. The electric heater 24 is arranged on the door frame 21. The bottom of the door frame 21 is engaged with the mounting slot 14. The two sides and the top outer wall of the door frame 21 are in contact with the inner wall of the wind box 12 and can be connected by screws.

[0048] The design of the mounting slot 14 serves as a fixing structure for fixing the door-shaped frame 21 and a water receiving tray for receiving water dripping from the wet film 23 , thereby eliminating the structural cost of the water receiving tray in the wet film humidification system.

[0049] In this embodiment, the spray humidification system sprays in a direction perpendicular to the air inlet direction. Specifically, the spray humidification system includes a spray humidifier 3 distributed along the air inlet direction. The spray humidifier 3 includes a spray pipe 31 and a pair of nozzles 32 arranged on the spray pipe 31. The paired nozzles 32 are symmetrically arranged and perpendicular to the air inlet direction. This allows the spray diffusion effect to be maintained even if one row of nozzles 32 is removed so that they do not spray in the same direction.

[0050] In this embodiment, the water distributor 22 and the spray pipe 31 are connected to an external water supply system 4. The external water supply system 4 includes a pump station 41 and a circulation pipeline 42 connected to the pump station 41. The water inlet pipeline of the circulation pipeline 42 is connected to the water tank 11, and the water outlet pipeline is connected to the spray pipe 31 and the water distributor 22. A valve 25 is provided on the water outlet pipeline connected to the water distributor 22.

[0051] The external water supply system 4 further includes a filter 43 , which is disposed on the water inlet and outlet pipes of the circulation pipe 42 to prevent impurities from affecting the pump station 41 and the two humidification systems.

[0052] The external water supply system 4 also includes a water supply pipe 44, one end of which is connected to the water tank 11, and the other end is connected to an external water source through a water pump. A liquid level gauge 45 is provided in the water tank 11, and the liquid level gauge 45 and the water pump are both connected to a controller. The liquid level gauge 45 can monitor the liquid level in the water tank 11 in real time. When the liquid level in the water tank 11 reaches the upper or lower limit of the liquid level threshold, the water pump can be stopped or started by the controller to realize intelligent water supply; wherein the controller can adopt a single-chip microcomputer, and its control principle, control method and communication are existing technologies, which are mature technologies that can be mastered by those skilled in the art. The control and communication between the liquid level gauge 45 and the water pump are also widely used in the existing technology. Since it is not the invention point of this case, it will not be described in detail in this case.

[0053] The external water supply system 4 also includes an overflow pipe 46 connected to the water tank 11. An overflow valve is provided on the overflow pipe 46. When the liquid level gauge 45 in the water tank 11 is damaged and fails, the water level reaches a certain height, and the overflow valve can be directly opened to discharge the water through the overflow pipe 46.

[0054] When using the above humidifier, there are two usage scenarios according to different humidification requirements:

[0055] Case 1 (small humidification capacity): The incoming air first passes through the spray humidification system. The pump station 41 extracts water from the water tank 11, filters it through the filter 43, and outputs it to the spray pipe 31. Finally, it is sprayed out from the nozzle 32 perpendicular to the incoming air direction, producing a water mist that diffuses perpendicular to the wind direction. The water mist contacts the incoming air and can initially humidify the incoming air. In addition, the water mist is also affected by the incoming air and diffuses backward into the wet film humidification system.

[0056] The incoming air after preliminary humidification is accompanied by water mist and then passes through the wet film humidification system. The water mist is captured by the wet film 23, and the wet film 23 is moistened. The electric heater 24 on the wet film 23 can evaporate the moisture on the wet film 23 by heating, thereby evaporating and humidifying the incoming air after preliminary humidification again.

[0057] Case 2 (larger humidification capacity): the incoming air first passes through the spray humidification system for preliminary humidification. The humidification principle is the same as that of case 1.

[0058] The incoming air after preliminary humidification passes through the wet film humidification system again. The valve 25 at the water distributor 22 is opened, and the pump station 41 extracts the water in the water tank 11, filters it through the filter 43 and outputs it to the water distributor 22. The water is then sprayed onto the wet film 23 through the water distributor 22 to moisten the wet film 23. The electric heater 24 on the wet film 23 can evaporate the moisture on the wet film 23 by heating, thereby evaporating and humidifying the incoming air after preliminary humidification again.

[0059] In the above-mentioned situation 1, the wet film 23 is evaporated and vaporized by the water mist generated by the spray humidification system to achieve secondary humidification. Since the amount of water mist generated by the spray humidification system is limited, the humidification effect is not as good as the humidification effect of directly using the external water supply system 4 to supply water to the wet film 23 in situation 2.

[0060] In this embodiment, since one spray pipe 31 and one wet film 23 are provided, compared with the design of two symmetrical spray pipes 51 in the conventional high-pressure spray humidifier (see Figure 6 ), the humidification capacity of this solution is slightly lower, which meets the needs of fresh air air conditioning in southern regions with moderate humidification capacity requirements; in addition, since the number of spray pipes 31 and nozzles 32 is reduced, the required flow rate is also reduced accordingly, and the supporting pump station 41 and the corresponding humidification control system will also reduce a certain cost. At the same time, the reduction in flow rate will also reduce the customer's operating costs; and the capture of water mist by the wet film 23 can replace the front and rear baffle structures 52 set in the spray-type high-pressure spray humidifier to prevent the water mist from diffusing to the outside of the inner tank, thereby eliminating the baffle cost; using the water tank 11 as a water receiving tray for the wet film 23 eliminates the cost of the water receiving tray, which can be said to kill two birds with one stone.

[0061] If the humidification capacity is to be increased on the basis of the solution of this embodiment, in other embodiments, two or more spray humidifiers 3 may be provided. Accordingly, in order to fully capture the water mist generated by the spray, two or more wet film humidifiers 2 may be provided, or the thickness of the wet film 23 may be directly increased (not shown in the figure).

[0062] When the amount of sprayed water mist is large, in order to prevent the water mist from spreading to the outside of the inner tank, in other embodiments, a water baffle can be further provided at the air inlet.

[0063] Finally, in this embodiment, from the perspective of the overall structure, there is not much change compared to the traditional counter-spray spray humidifier 3. It is only necessary to cancel the front and rear water baffles in the traditional humidifier, cancel one of the spray pipes 31, connect its water inlet pipe to the wet film humidifier 2, and then improve the structure of the water tank 11, and fix the frame of the wet film humidifier 2 in the water tank 11. The overall structure of the entire solution does not require complex design and production process changes, and can also reduce production costs and operating costs and increase profits under the same requirements. Example

[0064] This embodiment is basically the same as Embodiment 1, except that: two or more spray humidification systems and two or more wet film humidification systems are provided in the humidifier inner tank 1; the spray humidification systems and the wet film humidification systems are alternately distributed along the air inlet direction, and the wet film humidification system is located on the air outlet side (not shown in the figure).

[0065] The technical solution of this embodiment is suitable for use in situations where high humidification capacity is required. The water mist generated by all spray humidification systems can be captured by the wet film 23 on the rear side or both sides, and then evaporated by the wet film 23, achieving alternating humidification of the incoming air and evaporation humidification.

[0066] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
