Description

Technical Field

[0001] This utility model is applicable to the field of humidifiers, and in particular relates to a dry steam humidifier device and an air conditioning unit that enhances steam diffusion and absorption functions. Background Technology

[0002] Dry steam humidifiers are a common type of humidifier used in air conditioning units and are widely used in various fields, such as pharmaceuticals, hospitals, electronics factories, mushroom cultivation rooms, computer rooms, textiles, tobacco, hotels, office buildings, and printing. During humidification, the humidifier's steam inlet is connected to a saturated steam source. The saturated steam is then ejected from the humidifier's nozzles, humidifying the surrounding air. In the air conditioning unit or duct, steam at temperatures above 100°C mixes with cooler air, resulting in heat exchange. When the steam releases heat, it condenses into visible water particles. These water particles absorb heat from the surrounding air and then vaporize, becoming humid air. This process is the absorption and vaporization process of a dry steam humidifier; the distance the steam travels to completely vaporize is the absorption distance. To achieve better absorption, dry steam humidifiers typically spray air against the direction of airflow. Upstream of the dry steam humidifier are usually other components, such as coils. Because air conditioning units are often limited by length, the distance between the dry steam humidifier and upstream components is usually shortened during process breakdown. However, since dry steam is sprayed against the airflow direction, if the distance is too short, the dry steam will hit the upstream components, causing corrosion and damage. Furthermore, the humidification absorption distance is insufficient, resulting in unsatisfactory humidification effects and posing challenges to the design of air conditioning units.

[0003] In summary, the problems existing in the relevant technologies urgently need to be solved. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a dry steam humidifier device and an air conditioning unit that enhances the steam diffusion and absorption function.

[0005] The technical solution adopted by this utility model to solve its technical problem is: In a first aspect, a dry steam humidifier device for enhancing steam diffusion and absorption functions includes a steam nozzle, a nozzle outer sleeve, and a flow guiding component. The nozzle outer sleeve has an inner cavity and a steam inlet. The steam nozzle is connected to the nozzle outer sleeve. A portion of the pipe wall of the steam nozzle is disposed within the inner cavity. A steam through-hole communicating with the inner cavity is provided on the pipe wall of the steam nozzle located within the inner cavity. A portion of the pipe wall of the steam nozzle is disposed outside the inner cavity. A steam nozzle hole is provided on the pipe wall of the steam nozzle located outside the inner cavity. The flow guiding component is disposed on the opposite side of the steam nozzle hole. The flow guiding component has a protrusion extending towards the steam nozzle hole. A gap is left between the flow guiding component and the steam nozzle, and a steam channel branching off to both sides is formed through the protrusion.

[0006] In conjunction with the first aspect, in some implementations of the first aspect, the nozzle sleeve extends along the length direction, and the nozzle sleeve has a V-shaped concave surface extending along the length direction on one side wall facing the guide member, and a slot extending along the length direction is provided at the bottom of the V-shaped concave surface. The steam nozzle extends along the length direction, the steam nozzle is disposed in the inner cavity, and a portion of the pipe wall of the steam nozzle protrudes outside the inner cavity through the slot.

[0007] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the protrusion of the flow guiding component is V-shaped, and a steam channel that branches off to both sides in a V-shape is formed between the flow guiding component and the V-shaped concave surface.

[0008] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the flow guiding component includes a flow guiding plate that extends along the length direction and is bent toward the V-shaped concave surface to form the protrusion.

[0009] In combination with the first aspect and the above-described implementation methods, in some implementation methods of the first aspect, the guide plate is provided with flow equalization holes.

[0010] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the edge of the guide vane is provided with flanges extending to both sides, and a guide vane fixing member is provided on the back side of the flange, and is installed on the nozzle outer sleeve through the guide vane fixing member.

[0011] In combination with the first aspect and the above-described implementations, some implementations of the first aspect further include a vapor-liquid separator connected to the steam inlet.

[0012] In combination with the first aspect and the above-mentioned implementation methods, in some implementation methods of the first aspect, the nozzle outer sleeve is provided with a primary circulation return steam port, and the primary circulation return steam port is connected to the vapor-liquid separator through a pipeline.

[0013] In a second aspect, an air conditioning unit includes a heat exchanger and a dry steam humidifier device for enhancing steam diffusion and absorption function as described in any implementation of the first aspect, wherein the dry steam humidifier device for enhancing steam diffusion and absorption function is disposed behind the heat exchanger along the air outlet direction of the air conditioning unit, and the flow guiding component is oriented toward the heat exchanger.

[0014] In conjunction with the second aspect, in some implementations of the second aspect, including some of the dry steam humidifier devices with enhanced steam diffusion and absorption functions described in the first aspect, the primary circulation return steam port is located at one end of the nozzle jacket, and the dry steam humidifier device with enhanced steam diffusion and absorption functions is inclined toward the end where the primary circulation return steam port is located.

[0015] One of the above technical solutions has at least one of the following advantages or beneficial effects: During humidification, the steam inlet is connected to a saturated steam source. The saturated steam flows within the inner cavity of the nozzle jacket, preheating the steam nozzle. Dry steam enters the steam nozzle through the steam through-hole and is ejected from the steam nozzle orifice, thus humidifying the surrounding air. During this process, the flow guiding component hinders further forward diffusion of the dry steam, protecting upstream components from corrosion and damage caused by the dry steam. Simultaneously, the flow guiding component causes the ejected dry steam to diffuse laterally along the steam channel, increasing the contact area with the airflow. The dry steam changes from a horizontal flow to a vortex flow, shortening the absorption distance of the dry steam humidifier and ensuring humidification effectiveness while protecting upstream components.

[0016] In this invention, a guide component is added before the steam nozzle to increase airflow turbulence, transforming the airflow from a horizontal state to a vortex state, thereby increasing absorption efficiency and reducing absorption distance. It also protects the upstream components from corrosion and damage by the steam. This invention features a simple design, making it more suitable for air conditioning units that require the installation of a dry steam humidifier and whose length is limited.

[0023] in, Figure 4The reference direction coordinate system of this utility model embodiment is given below, in conjunction with Figure 4 The embodiments of this utility model will be described in the directions shown.

[0024] See Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a dry steam humidifier device with enhanced steam diffusion and absorption function, comprising a steam nozzle 100, a nozzle outer sleeve 200, and a flow guiding component 300. The nozzle outer sleeve 200 has a shell-like structure and an inner cavity 201. The nozzle outer sleeve 200 has a steam inlet. The steam nozzle 100 is connected to the nozzle outer sleeve 200. A portion of the pipe wall of the steam nozzle 100 is disposed within the inner cavity 201. The pipe wall of the steam nozzle 100 within the inner cavity 201 has a steam through hole communicating with the inner cavity 201. Steam entering the nozzle outer sleeve 200 from the steam inlet can further enter the steam nozzle 100 through the steam through hole. A portion of the pipe wall of the steam nozzle 100 is disposed outside the inner cavity 201. The pipe wall of the steam nozzle 100 outside the inner cavity 201 has a steam nozzle. The flow guiding component 300 is disposed on the opposite side of the steam nozzle, for example, in... Figure 4 In the embodiment shown, the front part of the pipe wall of the steam nozzle 100 is located outside the inner cavity 201 and is provided with steam nozzle holes. The flow guide 300 is provided in front of the steam nozzle 100. The flow guide 300 is provided with a protrusion 301 extending in the direction of the steam nozzle holes. There is a gap between the flow guide 300 and the steam nozzle 100, and the protrusion 301 forms a steam channel 400 that branches off to both sides.

[0025] Combination Figure 4 During humidification, the steam inlet is connected to a saturated steam source. The saturated steam flows within the inner cavity 201 of the nozzle jacket 200, preheating the steam nozzle 100 and raising its temperature to prevent or reduce pre-condensation of steam within the nozzle. Dry steam enters the nozzle 100 through steam through-holes and exits from the steam nozzles, humidifying the surrounding air. During this process, the flow guide 300 hinders further forward diffusion of the dry steam, protecting upstream components from corrosion and damage. Simultaneously, the flow guide 300 causes the ejected dry steam to diffuse laterally along the steam channel 400, increasing the contact area with the airflow. The dry steam changes from a horizontal flow to a vortex flow, shortening the absorption distance of the dry steam humidifier and ensuring humidification while protecting upstream components.

[0026] In this invention, a guide component 300 is added before the steam nozzle 100 to increase airflow turbulence, transforming the airflow from a horizontal state to a vortex state, thereby increasing absorption efficiency and reducing absorption distance. It also protects the upstream components from corrosion and damage by the steam. This invention features a simple design, making it more suitable for air conditioning units that require the installation of a dry steam humidifier and whose length is limited.

[0027] In some embodiments, see Figures 1-4 The nozzle sleeve 200 extends along its length. On one side wall facing the flow guide component 300, the nozzle sleeve 200 has a V-shaped concave surface 202 extending along its length. The bottom of the V-shaped concave surface 202 has a slot 203 extending along its length. The steam nozzle 100 extends along its length and is disposed within the inner cavity 201. A portion of the steam nozzle 100's wall protrudes from the inner cavity 201 through the slot 203. The steam nozzle 100 can be welded to the nozzle sleeve 200 at the slot. In this embodiment, the nozzle sleeve 200 covers most of the steam nozzle 100, exposing only a portion of the steam nozzle 100's wall at the slot. This increases the preheating capacity of the nozzle sleeve 200 for the steam nozzle 100 while ensuring steam ejection.

[0028] Further, see Figure 1 , Figure 3 , Figure 4 The protrusion 301 of the flow guide component 300 is V-shaped, and a V-shaped steam channel 400 is formed between the flow guide component 300 and the V-shaped concave surface. In this embodiment, by forming a V-shaped steam channel 400 between the flow guide component 300 and the V-shaped concave surface, the steam ejected from the steam nozzle 100 is pushed aside, increasing the contact range and area between the steam and the airflow, avoiding air saturation caused by humidification in a small area, thereby improving humidification efficiency.

[0029] In some embodiments, see Figure 1 , Figure 4 The flow guiding component 300 includes a flow guiding plate that extends along its length and bends towards a V-shaped concave surface to form a protrusion 301. In this embodiment, the flow guiding component 300 is made of sheet metal, has a simple structure, is easy to process, and can be customized in size without mold opening. It can be designed according to different sizes and lengths of dry steam nozzles 100; it offers a wide range of choices, strong compatibility, and simple installation.

[0030] In some embodiments, see Figure 1 , Figure 2The guide plate is provided with flow equalization holes 302. The flow equalization holes 302 make the sprayed dry steam diffuse evenly to the surroundings, increasing the contact area with the airflow, while reducing the resistance after the steam is sprayed out. Moreover, the flow equalization holes 302 can also reduce the contact area between the sprayed steam and the guide plate, thereby reducing the steam from being condensed and liquefied on the guide plate.

[0031] In some embodiments, see Figure 1 , Figure 4 The guide plate has flanges 303 extending to both sides along its edge. A guide plate fixing member 304 is located on the back side of the flange 303, and the guide plate is mounted to the nozzle outer sleeve 200 via the guide plate fixing member 304. During installation on an air conditioning unit, the nozzle outer sleeve 200 and steam nozzle 100 are installed and fixed inside the air conditioning unit through pre-drilled holes. Then, the dry steam guide plate is installed and fixed to the nozzle outer sleeve 200 via the guide plate fixing member 304. This embodiment has a simple structure, facilitating the installation of the entire device on an air conditioning unit.

[0032] In some embodiments, see Figure 1 , Figure 2 The dry steam humidifier device that enhances the steam diffusion and absorption function also includes a vapor-liquid separator 500, which is connected to the steam inlet and is used to separate the liquid in the steam to improve the steam humidification effect.

[0033] Further, see Figure 1 , Figure 2 The nozzle jacket 200 is equipped with a primary circulation return steam port, which is connected to the vapor-liquid separator 500 via a pipeline. Water generated inside the nozzle jacket 200 for preheating the steam nozzle 100 can flow back to the vapor-liquid separator 500 through the primary circulation return steam port.

[0034] See Figure 5 , Figure 6 The present invention also provides an air conditioning unit, including a heat exchanger 600 and a dry steam humidifier device with enhanced steam diffusion and absorption function as described in any of the above embodiments. The dry steam humidifier device with enhanced steam diffusion and absorption function is arranged behind the heat exchanger 600 along the air outlet direction of the air conditioning unit, and the guide component 300 faces the heat exchanger 600. When the air conditioning unit is working, it agitates the airflow flowing through the heat exchanger 600. After the airflow exchanges heat with the heat exchanger 600, it flows through the dry steam humidifier device with enhanced steam diffusion and absorption function, and mixes with the steam sprayed by the dry steam humidifier device with enhanced steam diffusion and absorption function to achieve humidification.

[0035] In some embodiments, the primary circulation return steam port is located at one end of the nozzle jacket 200, and the dry steam humidifier device that enhances steam diffusion and absorption is inclined toward the end where the primary circulation return steam port is located. This allows the water condensed inside the nozzle jacket 200 to automatically flow back to the primary circulation return steam port under the influence of gravity.
