[ example 1 ]

The embodiment provides a transverse wave atomization structure, which comprises a bearing mechanism, a conveying pipe and a vibration device, wherein the conveying pipe and the vibration device are arranged on the bearing mechanism. The delivery tube is a rigid conduit, such as a rigid metal conduit.

In one embodiment as shown in fig. 2, the core part of the transverse wave atomizing structure is composed of a delivery pipe 21 for delivering the liquid to be liquefied, a support frame 22, an electromagnetic vibrator 23, a vibration receiving block 24, an atomizing chamber 25, and the like. The delivery tube 21 is made of a corrosion resistant rigid material such as stainless steel tubing or other metal piping. The support frame 22 is used to fix the liquid feed pipe 21 and the electromagnetic oscillator 23. The atomizing chamber 25 and the support frame 22 may be integrally formed. The atomizing chamber 25 is provided with a raffinate recovery port 26, an air flow input port 27, an aerosol output port 28, and a probe port for the liquid transport tube 21. The delivery tube 21 has an input port 29 and an output port 210, the output port 210 being inserted into the nebulizing chamber 25 from a probe of the nebulizing chamber 25.

The both ends of conveyer pipe 21 erect respectively on the founding wall of support frame 22 and atomizing chamber 25 to be equipped with first buffering sealed piece 211 and second buffering sealed piece 212 respectively, two buffering sealed

pieces

211, 212 are made by corrosion-resistant flexible rubber, are used for: fixing the delivery pipe 21: the friction force between the delivery pipe 21 and the vertical wall of the support frame 22/the atomizing cavity 25 is increased, so that the delivery pipe 21 is not transversely dislocated in vibration; damping: buffering the high-frequency mechanical vibration of the delivery pipe 21, preventing the vibration from being transmitted to the support frame 22 and the vertical wall of the atomizing cavity 25, and enabling the delivery pipe 21 to have a certain free vibration space; sealing: prevent the liquid fog (gas fog) in the atomizing cavity from permeating and diffusing to the space where the electromagnetic oscillator 23 is arranged, and prevent the oil from climbing inside and outside the whole structure.

The electromagnetic vibrator 23 and the vibration receiving block 24 constitute a vibration device for applying high-frequency mechanical vibration to the pipe wall of the delivery pipe to make liquid molecules in the delivery pipe move in transverse waves, get rid of the constraint of the delivery pipe at the output port of the delivery pipe, and emit the liquid molecules into mist to form liquid mist (aerosol).

The electromagnetic vibrator 23 is rigidly fixed to the support frame 22 and is not shown in detail. The electromagnetic vibrator 23 includes a core and a coil wound around the core, and when a high-frequency current is supplied to the coil, a fluctuating magnetic field having the same frequency is generated around the coil, and the core concentrates the high-frequency magnetic field at both ends of the core.

The vibration receiving block 24 is rigidly connected and fixed with the delivery pipe 21, and the vibration receiving block 24 is a permanent magnet or soft iron. The vibration receiving block 24 is located at the end of the magnetic core of the electromagnetic vibrator 23 with a certain gap from the magnetic core. When high-frequency current flows through the coil of the electromagnetic vibrator 23, a high-frequency magnetic field is generated at the end of the magnetic core of the electromagnetic vibrator 23, and the vibration receiving block 24 generates high-frequency mechanical vibration along the radial direction of the conveying pipe 21 under the action of the high-frequency magnetic field, and transmits the vibration to the conveying pipe 21 through rigid connection, so that the pipe wall of the conveying pipe 21 generates the same high-frequency mechanical vibration.

When the liquid to be atomized flows from the input port 29 to the output port 210 of the liquid delivery pipe 21, the high-frequency mechanical vibration from the electromagnetic vibrator 23 excites the liquid in the delivery pipe 21 through the vibration receiving block 24 and the delivery pipe 21, so that the liquid moves in a transverse wave and is released at the output port 210 to be atomized to form liquid mist. At this time, the air flow from the air flow input port 27 entrains the liquid mist near the output port 210, and the liquid mist is blown out from the gas mist output port 28 and enters the ambient air.

Optionally, the outlet port 210 of the delivery tube 21 is beveled to force the liquid mist released therefrom to be directed obliquely upwardly, facilitating the flow of air from the airflow input 27 to better carry the liquid mist out of the nebulizing chamber 25. However, because there may be insufficient atomization, or the droplets adhere to the inside of the atomization chamber 25 and gradually accumulate, there may be residual liquid in the atomization chamber 25 that is not atomized, and the residual liquid is collected by the atomization chamber, then flows to the bottom of the atomization chamber 25, and is recovered through the residual liquid recovery port 26. The recovered raffinate can be injected again into the feed pipe 21 through the input port 29.

It should be noted that, in some other embodiments, the electromagnetic vibrator 23 in this embodiment may also be replaced by other controllable vibration devices, including but not limited to a piezoelectric ultrasonic transducer, an electric field vibrator, etc., and whether the vibration receiving block 24 needs to be correspondingly arranged is determined by correspondingly adjusting the installation manner of the vibration devices according to the output force and the operation manner of the piezoelectric ultrasonic transducer, the electric field vibrator, etc.
