超聲波清洗機(jī)的脫氣是什么原理及功能呢？

作者：admin來源：http://m.ebaisha.cn/時(shí)間：2020-10-17

很多在超聲波清洗機(jī)設(shè)備上都有脫氣，那么這個(gè)到底是什么原理和功能，下面就為大家解答：

Many of them are available on ultrasonic cleaning machines. So what is the principle and function of this, here are the answers:

當(dāng)超聲波進(jìn)入溶液時(shí)，會(huì)產(chǎn)生交變壓力。用于空化閾值的聲波在液體中傳播時(shí)會(huì)產(chǎn)生空化氣泡，能顯著提高氣體從溶液到氣泡的傳質(zhì)速率。空化氣泡是由溶液中的微小氣核產(chǎn)生的，這些氣核是由聲波稀相的拉應(yīng)力（負(fù)壓）產(chǎn)生的。

When ultrasonic wave enters the solution, alternating pressure will be generated. The cavitation bubble will be produced when the acoustic wave used for cavitation threshold propagates in liquid, which can significantly improve the mass transfer rate of gas from solution to bubble. Cavitation bubbles are produced by the tiny gas cores in the solution, which are produced by the tensile stress (negative pressure) of the dilute phase of sound waves.

如果在空化形成后拉伸應(yīng)力仍然存在，時(shí)空氣泡將膨脹到其初始尺寸的許多倍。在這種情況下，空化氣泡保持球形，然后增長、振動(dòng)和塌陷。當(dāng)超聲波作用時(shí)，溶液中的氣體成分可以通過氣液界面的“定向擴(kuò)散”進(jìn)入空化泡，空化泡進(jìn)入人的生長階段。當(dāng)空化氣泡在溶液表面塌陷時(shí)，氣體會(huì)從氣泡中逸出，從而引起脫氣。

If the tensile stress still exists after cavitation, the bubble will expand to many times its initial size. In this case, the cavitation bubble remains spherical, then grows, vibrates and collapses. When ultrasonic is applied, the gas components in the solution can enter into cavitation bubbles through the "directional diffusion" of the gas-liquid interface, and the cavitation bubbles enter the growth stage of human beings. When the cavitation bubble collapses on the surface of the solution, the gas will escape from the bubble, which will cause degassing.

超聲波脫氣設(shè)備的優(yōu)點(diǎn)是，泡沫是大量氣泡聚集而成，超聲波脫氣設(shè)備是在泡沫形成的早期，氣泡不是大量積聚的液體消泡、除氣，或者溶解，混合在液體氣體中消泡、除氣。整個(gè)過程不使用任何消泡劑，完全是物理消泡，也可以稱為機(jī)械消泡。對(duì)于已經(jīng)產(chǎn)生的表面泡沫，該裝置沒有明顯的效果，需要用消泡膜來解決。

The advantage of the ultrasonic degassing equipment is that the bubbles are gathered by a large number of bubbles. The ultrasonic degassing equipment is in the early stage of the bubble formation. The bubbles are not a large number of accumulated liquid defoaming, degassing, or dissolving, and are mixed in liquid gas to defoaming and degassing. The whole process does not use any defoaming agent, it is completely physical defoaming, also can be called mechanical defoaming. For the surface foam that has been produced, the device has no obvious effect and needs to be solved by the antifoaming film.

脫氣主要采用超聲波“定向擴(kuò)散”，一旦空化發(fā)生，內(nèi)部仍有空氣，在一些熔融液體脫氣凈化應(yīng)用中不產(chǎn)生空化。排出液體空氣，降低超聲波空化反應(yīng)產(chǎn)生氣泡的阻力，提高超聲波清洗機(jī)的清洗效率。另一個(gè)影響是超聲波清洗機(jī)工作時(shí)間長了會(huì)產(chǎn)生一種超聲波疲勞，降低清洗效果和效率，排氧氣功也能消除這種超聲波疲勞。

Degassing mainly adopts ultrasonic "directional diffusion", once cavitation occurs, there is still air inside, and there is no cavitation in some degassing and purification applications of molten liquid. The liquid air is discharged, the resistance of bubbles produced by ultrasonic cavitation reaction is reduced, and the cleaning efficiency of ultrasonic cleaning machine is improved. Another effect is that the ultrasonic cleaning machine will produce a kind of ultrasonic fatigue after working for a long time, which can reduce the cleaning effect and efficiency, and the oxygen exhaust gas can also eliminate this kind of ultrasonic fatigue.

綜上所述，可以看出超聲波清洗設(shè)備的非常強(qiáng)大，可以更好地達(dá)到清洗的目的，提高清洗效果。

In conclusion, it can be seen that the ultrasonic cleaning equipment is very powerful, and can better achieve the purpose of cleaning and improve the cleaning effect.
