the ultrasonic deicing device utilizes the design principle of utilizing the mechanical effect, the thermal effect and the cavitation effect of ultrasonic waves. Mechanical effects refer to the mechanical action of ultrasound that can cause emulsification of liquids, liquefaction of gels, and dispersion of solids. When standing waves are formed in the ultrasonic fluid medium, tiny particles suspended in the fluid are condensed at nodes due to the action of mechanical force, and form periodic accumulation in space;
when ultrasonic vibration is transmitted in the ice layer, on one hand, due to the fact that the density of the ice layer is uneven, ultrasonic waves can generate speed difference when passing through the ice layer, so that shearing force is generated to achieve a deicing effect, on the other hand, the ultrasonic vibration can drive molecules in the ice layer to vibrate, hydrogen bonds between the ice layers are damaged, so that the ice is melted into free water molecules, and the melted water molecules cannot be frozen continuously due to the mechanical effect of the ultrasonic vibration when being transmitted in the free water molecules, and a damage effect can be caused to the ice layer;
the thermal effect means that heat is generated in the vibration and wave propagation processes, so that the similar result of deicing by a heating method can be achieved. The cavitation effect is a unique property of ultrasonic waves in water, and refers to a dynamic process of growth and collapse when micro gas core cavitation bubbles in liquid vibrate under the action of sound waves and sound pressure reaches a certain value. Cavitation generally comprises 3 stages: formation, growth and violent collapse of cavitation bubbles. When ultrasonic waves are introduced into a container filled with liquid, tens of thousands of tiny bubbles, namely cavitation bubbles, are generated due to the vibration of the liquid. These bubbles grow in the negative pressure zone formed by the longitudinal propagation of the ultrasound waves and rapidly close in the positive pressure zone, thus being compressed and stretched under alternating positive and negative pressures. At the moment the bubble is compressed until collapse, a large instantaneous pressure is generated, typically up to tens to hundreds of mpa.
The cavitation can make the temperature of the gas phase reaction zone reach about 5200K, the effective temperature of the liquid phase reaction zone reach about 1900K, the local pressure is 5.O5 multiplied by 10kPa, the temperature change rate reaches 10K/s, and the cavitation is accompanied by strong shock waves and microjet with the speed per hour reaching 400 km. The huge instantaneous pressure can cause the surface of the solid suspended in the liquid to be damaged sharply;
ultrasonic cavitation is generally divided into 2 types of stable cavitation and transient cavitation: steady state cavitation refers to cavitation bubbles produced at low acoustic intensities (typically less than 10w/cm), the size of which oscillates around its equilibrium size, generating cycles for several cycles. When the resonance frequency of the ultrasonic transducer is enlarged to be equal to the sound wave frequency, the maximum energy coupling of the sound field and the bubbles occurs, and obvious cavitation is generated. Transient cavitation refers to cavitation bubbles (mostly occurring in 1 sound wave period) with short life cycle generated under the action of large sound intensity (generally more than 10 w/cm);
ultrasonic waves can generate a large number of small bubbles when applied to a liquid. One reason is that a tensile stress locally occurs in the liquid to form a negative pressure, and the reduction in pressure supersaturates the gas originally dissolved in the liquid to escape from the liquid as small bubbles. Another reason is that strong tensile stresses "tear" the liquid into a void, known as cavitation. The cavity is filled with a liquid vapor or another gas dissolved in the liquid, and may even be a vacuum. The small bubbles formed by cavitation can continuously move, grow or suddenly break down along with the vibration of the surrounding medium, and due to ultrasonic cavitation, after ultrasonic waves pass through melted water molecules, certain damage can be caused to an ice layer at an ice-water mixed interface, so that the deicing effect reaches a virtuous cycle.
The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited thereto. In the technical idea scope of the present invention, it can be right to the technical solution of the present invention perform multiple simple modifications, including each technical feature combined in any other suitable manner, these simple modifications and combinations should be regarded as the disclosed content of the present invention, and all belong to the protection scope of the present invention.
