A research team at the University of Southampton in the UK has developed a new type of ultrasonic cleaning device based on long-term basic research. The device can greatly reduce the water consumption and power consumption when using a high-pressure water gun cleaning device, and can be widely used in medical and health fields, food processing, machinery manufacturing, nuclear industry and other fields.

The invention won the Royal Society Brian Mercer Award for Innovation 2011 in 2011 with a prize of £ 250,000. When the award was announced, the Royal Society believed that the research could greatly improve the ability of the water cleaning process and was a revolutionary breakthrough.

The ultrasonic cleaning device invented by Professor Tim Leighton and Dr. Peter Birkin, the two main researchers, consumes only about 10% of water and electricity, and consumes about 2 liters / minute of water and 200 watts of power. At the same time, the device can use cold water, thereby saving the energy required for water supply heating. The cleaning process can reduce the discharge of sewage and polluted aerosols, thereby reducing the cost of subsequent environmental protection treatment.

The working principle of the new device is to generate bubbles and ultrasonic waves at the same time, to reach the dirt surface with the water flow, to find and enter the dirt gap, through the action of the shear force similar to the eroded river bank, the dirt soil collapsed. The device can adjust the high and low gear of the guide, and it can be used to clean soft surfaces such as hands or food when running in low gear.

The previous ultrasonic cleaning technology is ultrasonic bathing, which can only clean smaller objects that can be placed in the ultrasonic pool, and cannot be used to wash hands and other vulnerable objects. In addition, a large amount of sewage and aerosol will be generated, which brings a lot of problems and costs in some occasions, such as the cleaning process in the nuclear industry.

At present, a number of enterprises in the medical equipment, food preparation, manufacturing and power equipment industries have obtained authorizations for related patents and jointly developed related products with inventors.
