Description

Technical Field

[0001] This invention relates to the field of spray humidifier technology, and more specifically, to a humidifier device that combines a steam and a water-air mixing atomizing nozzle. Background Technology

[0002] In tobacco manufacturing, controlling relative humidity is crucial for ensuring product quality. During tobacco fermentation, humidification adjustment, and processing, appropriate humidity helps the tobacco leaves reach ideal conditions, improving the quality and taste of the tobacco. Traditional humidifiers typically use steam or atomization, which presents several problems. While steam humidifiers provide humidity, their single humidification method makes precise humidity control difficult. Atomization, although releasing moisture into the air, can lead to uneven humidity levels due to water droplets that are too large or too small, affecting the stability and quality of the tobacco manufacturing process. Summary of the Invention

[0003] To address the above shortcomings, the present invention aims to provide a humidifier device that combines a steam and a water-air mixing atomizing nozzle, in order to solve the problems of traditional steam humidifiers having difficulty in achieving precise humidity control and atomizing humidification easily leading to uneven humidity.

[0004] To achieve the above objectives, the present invention provides a humidifier device combining steam and air-water mixing atomizing nozzles, comprising: a mixing chamber, wherein a plurality of air-water mixing atomizing nozzles are uniformly arranged on the chamber wall; a steam chamber, located at the front end of the mixing chamber, wherein a steam nozzle extending into the mixing chamber is provided at the outlet end of the steam chamber; and a diffuser, located at the rear end of the mixing chamber.

[0005] Preferably, the steam nozzle has a tapered nozzle that is wide at both ends and narrow in the middle.

[0006] Preferably, the mixing chamber has four evenly arranged air-water mixing atomizing nozzles on its wall, the nozzle directions of the four air-water mixing atomizing nozzles are parallel to the tangential direction of the conical nozzle, and the air-water mixing atomizing nozzles are arranged in front of the conical nozzle.

[0007] Preferably, the wall of the mixing chamber is provided with sharp protrusions corresponding to the nozzle direction of the gas-water mixing atomizing nozzle.

[0008] Preferably, the sharp protrusion has a triangular structure.

[0009] Preferably, the rear end of the mixing chamber is narrowed by a tapered constriction that is wider at the inner end and narrower at the outer end.

[0010] Preferably, the diffuser has a conical cylinder structure.

[0011] Preferably, the step connecting the rear end of the tapered constriction to the inner wall of the mixing chamber has a rounded corner structure.

[0012] Preferably, the steam nozzle includes a T-shaped seat that is threaded to the outer wall of the mixing chamber, an atomizing core inserted into the T-shaped seat, and a nozzle located at the bottom of the atomizing core. The atomizing core is provided with a valve needle and a valve cap.

[0013] Preferably, the steam chamber has a cylindrical structure, and the front end of the steam chamber is provided with a flange structure.

[0014] Compared with existing technologies, the present invention has the following advantages:

[0015] (1) In the humidifier device of the present invention, which combines steam and air-water mixing atomizing nozzle, the advantages of steam humidification and atomizing humidification are realized, achieving precise control of humidity and uniformity of humidity. It can achieve fine control of humidification amount, adapt to the humidity requirements of different environments. When the humidification amount is sufficient, only steam humidification is used. When the humidification amount is insufficient, the air-water mixing atomizing nozzle is activated to make up for the humidification gap, improving the flexibility of use and enabling the system to adapt to different working conditions.

[0016] (2) In the humidifier device of the invention that combines steam and gas-water mixing atomizing nozzle, the gas-water mixing atomizing nozzle and the steam nozzle are installed tangentially, and the tangential water mist is sprayed out and fully mixed with the steam. The gas-water mixing atomizing nozzle technology is used to refine the water droplets and mix them with the steam, thereby improving the mixing efficiency, ensuring the uniformity of the mixture, and thus improving the system efficiency.

[0017] (3) In the humidifier device of the present invention, which combines steam and gas-water mixing atomizing nozzle, the gas-water mixing atomizing nozzle and the steam nozzle can improve the stability and reliability of the system, reduce the failure rate, reduce the frequency and cost of system maintenance, and improve the long-term maintainability of the system through carefully designed orifice positions and nozzle positions.

[0018] (4) In the humidifier device of the present invention, which combines steam and water mixing atomizing nozzle, the steam and atomized water droplets in the mixing chamber can be mixed without dead angles, thereby achieving a certain degree of energy saving and efficiency improvement, and ensuring the uniformity of temperature after mixing.

[0019] (5) In the humidifier device of the present invention, which combines steam and gas-water mixing atomizing nozzle, the gas-water mixing atomizing nozzle and the steam nozzle are installed tangentially. The tangential arrangement helps to improve the kinetic energy transfer efficiency of steam, and more steam kinetic energy is transferred to the mixture. This enhances the disturbance intensity of steam and atomized water droplets in the mixing chamber and can reduce fluid friction and pressure loss inside the steam ejector, because steam can pass through the tangential arrangement more easily without being subjected to too much resistance.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The embodiments of the present invention will be described below according to the overall structure of the present invention.

[0028] The specific implementation of this invention is as follows:

[0029] like Figures 1-5 As shown, a humidifier device combining steam and air-water mixing atomizing nozzles includes: a mixing chamber 2, on which a plurality of air-water mixing atomizing nozzles 4 are uniformly arranged; a steam chamber 1, located at the front end of the mixing chamber 2, with a steam nozzle 5 extending into the mixing chamber 2 at the outlet end of the steam chamber 1; and a diffuser 3, located at the rear end of the mixing chamber 2.

[0030] In the humidifier device of the present invention, which combines a steam and a water-gas mixing atomizing nozzle, one end of the mixing chamber 2 is connected to the steam chamber 1, and the steam chamber 1 is connected to a steam pipeline. Steam is injected into the steam chamber 1 through the steam pipeline. After the steam is accelerated by the steam nozzle 5, it is then diffused by the diffuser 3, so that the steam can be sprayed out over a wide area to uniformly humidify the tobacco leaves, resulting in a good humidification effect.

[0031] A gas-water mixing atomizing nozzle 4 is installed on the mixing chamber 2. The two ends of the gas-water mixing atomizing nozzle 4 are connected to a high-pressure water pipe and a compressed air pipe, which can spray water mist into the mixing chamber 2.

[0032] When it is necessary to improve the humidification effect and efficiency of tobacco leaves, steam is injected into the steam chamber 1 through the steam pipeline. After being accelerated by the steam nozzle 5, the steam is fully mixed with the water mist in the mixing chamber 2, and then a wide range of atomized steam is sprayed out from the diffuser 3. The flow rate of water mist sprayed from the gas-water mixing atomizing nozzle 4 can be adjusted according to the humidity requirements to achieve precise humidity adjustment, meet the humidity requirements of tobacco fermentation, and ensure the high quality and stability of tobacco production.

[0033] In a preferred embodiment of this invention, the steam nozzle 5 is provided with a conical nozzle 51 that is wide at both ends and narrow in the middle. The conical nozzle 51 is wide at both ends and narrows in the middle, which can pressurize and accelerate the steam before it is ejected, thereby increasing the steam flow rate and the steam ejection range.

[0034] In a preferred embodiment, the mixing chamber 2 has four evenly arranged air-water mixing atomizing nozzles 4 on its wall. The nozzle directions of the four air-water mixing atomizing nozzles 4 are parallel to the tangential direction of the conical spray hole 51, and the air-water mixing atomizing nozzles 4 are positioned in front of the conical spray hole 51. The mixing chamber 2 also has four insertion holes for mounting the air-water mixing atomizing nozzles 4, with the center line of the insertion holes parallel to the tangential direction of the conical spray hole 51. In this embodiment, the water mist sprayed from the air-water mixing atomizing nozzles 4 can be fully mixed with the steam sprayed from the steam nozzle 5 to obtain a combination of steam and water mist with high humidity.

[0035] In a preferred embodiment, the mixing chamber 2 has sharp protrusions 6 on its wall corresponding to the nozzle direction of the air-water mixing atomizing nozzle 4. These sharp protrusions 6 are triangular structures. In this embodiment, the wall of the mixing chamber 2 is covered with small triangular structures, which allows for adjustment of the inner wall roughness. The atomized water droplets collide with the triangular structures on the wall at high speed, resulting in finer atomized water droplets. Furthermore, the inner cavity of the mixing chamber 2 is a circular hole structure, with the insertion hole extending from the hole wall in a direction close to the tangent of the hole wall. This ensures that the air jet direction of the air-water mixing atomizing nozzle 4 is close to the tangent direction, allowing the atomized mist ejected from the nozzle 4 to fully collide with the triangular structures, resulting in even finer mist.

[0036] In a preferred embodiment of this invention, the mixing chamber 2 is provided with a circular inner cavity, the diameter of which is larger than the diameter of the steam chamber 1. The rear end of the mixing chamber 2 is narrowed and provided with a conical constriction 21 that is wider at the inner end and narrower at the outer end. The function of the conical constriction 21 is to pressurize and accelerate the steam-water mist mixture in the mixing chamber 2 and then spray it out from the diffuser 3 to a wide range of steam-water mist.

[0037] In a preferred embodiment of this invention, the diffuser 3 is a conical cylinder structure that is wide at the front end and narrow at the rear end, which increases the spray range of steam water mist and allows the steam water mist to be sprayed out as finer water mist after pressure reduction.

[0038] In a preferred embodiment of this invention, a rounded corner structure 14 is provided on the step connecting the rear end of the conical constriction 21 to the inner wall of the mixing chamber 2. The rounded corner structure 14 makes the conical constriction 21 smoothly transition to the inner wall of the mixing chamber 2, reducing the resistance received by the fluid and reducing energy loss.

[0039] In a preferred embodiment of this invention, the steam nozzle 5 includes a T-shaped seat 8 threadedly connected to the outer wall of the mixing chamber 2, an atomizing core 11 inserted into the T-shaped seat 8, and a nozzle 9 located at the bottom of the atomizing core 11. The atomizing core 11 is provided with a valve needle 7 and a valve cap 10. The two ends of the T-shaped seat 8 are provided with a water inlet connector 12 and an air inlet connector 13. The water inlet connector 12 and the air inlet connector 13 are respectively connected to a high-pressure water pipe and a compressed air pipe. The flow rate of the sprayed water mist can be adjusted by adjusting the flow rate of the water inlet connector 12 and the air inlet connector 13.

[0040] In a preferred embodiment of this invention, the steam chamber 1 is a cylindrical structure, and the front end of the steam chamber 1 is provided with a flange structure 15, which is detachably connected to the steam pipe through the flange structure 15, making the connection quick and the operation simple.

[0041] Working principle:

[0042] When only steam is used for humidification, the steam chamber 1 at one end of the mixing chamber 2 is connected to the steam pipe through the flange structure 15 to connect the steam pipeline. Steam is injected into the steam chamber 1 through the steam pipeline. After the steam is accelerated by the steam nozzle 5, it is then diffused by the diffuser 3 so that the steam can be sprayed out over a wide area to humidify the tobacco leaves evenly, resulting in a good humidification effect.

[0043] When it is necessary to improve the humidification effect and efficiency of tobacco leaves, the two ends of the air-water mixing atomizing nozzle 4 are connected to a high-pressure water pipe and a compressed air pipe to spray water mist into the mixing chamber 2; steam is injected into the steam chamber 1 through the steam pipe. After being accelerated by the steam nozzle 5, the steam is fully mixed with the water mist in the mixing chamber 2, and then atomized steam is sprayed out from the diffuser 3. The flow rate of water mist sprayed from the air-water mixing atomizing nozzle 4 can be adjusted according to the humidity requirements to achieve precise humidity adjustment, meet the humidity requirements of tobacco fermentation, and ensure the high quality and stability of tobacco production.
