Enhancing biodiesel production from soybean oil using ultrasonics

Brief Introduction of Vibrating Bar of Ultrasound Cleaner:

Ultrasound refers to electromagnetic waves with frequencies ranging from 20 kHz to 50 MHz. It is a mechanical wave that needs energy carrier - medium to transmit. There exists a period of alternation of positive and negative pressure in the transmission process of ultrasound. In the positive phase, the medium molecules are squeezed to increase the original density of the medium. In the negative phase, the medium molecules are sparse and discrete, and the medium density decreases. That is to say, ultrasound can not polarize the molecules in the sample, but cause acoustic cavitation between the solvent and the sample, leading to the formation, growth and explosive compression of bubbles in the solution, thus dispersing the solid sample, increasing the contact area between the sample and the extracting solvent, and increasing the transfer of the target from the solid phase. Mass transfer rate of liquid phase. In industrial applications, the use of ultrasound for cleaning, drying, sterilization, atomization and non-destructive testing is a very mature and widely used technology.

Ultrasound vibrating rod generates radial vibration of rod body through high-power and large-amplitude transducer. Ultrasound is generated uniformly at 360 degrees near the vibrating rod. Its amplitude is between the ultrasonic cleaner and the processor. Therefore, the direction of use is flexible. Ultrasound vibrating rod can be used for cleaning any grooved body, can be placed in any position of the groove, and occupies a very small volume space, can be very flexible to use. Used in the reactor interior, it can be used to accelerate dissolution, accelerate reaction and prevent scaling on the inner wall, etc.

 

Functional characteristics of vibration rod of ultrasonic cleaning machine:

1. The stronger the power density of ultrasonic wave is, the liquid which can not be treated by low power density can be treated.

2. Multiple frequencies are available to solve every problem in every industry.

3. The material is made of national standard 304 stainless steel with a thickness of 1.0MM, which is strong, durable and high temperature resistant.

4. The imported standard 60W industrial magnitude earthquake head in Korea has concentrated strength and remarkable cleaning effect.

5. It can work continuously for a long time without interruption.

6. With generator control system, flexible operation **;

7. Cleaning, emulsification, separation, homogenization, extraction, catalysis, defoaming, stirring, etc.

8. The power output of the ultrasonic vibration rod is not affected by the changes of liquid level, tank capacity and temperature difference, and the power output is stable and uniform.

9. Ultrasound cavitation is generated around the rod, and the energy of the ultrasonic wave is distributed uniformly around the rod.

10. Sealing and waterproofing of ultrasonic shock rod, safe to use;

11. The service life of the ultrasonic vibrating rod is more than 1.5 times of that of the traditional ultrasonic vibrating plate.
