BACKGROUND OF THE INVENTION
A patent document (Chinese patent application number: 201811268975.7; publication number: CN109569390A) entitled “An Ultrasonic Oil Fuel Gasification Device” discloses a gasification device that converts oil fuel into gaseous state. The device comprises a casing with an inner chamber, filter screen components or filter cylinders, ultrasonic transducers, an ultrasonic generator, and a fuel injection and air input module. The casing is provided with an input port and an output port in communication with each other, and the fuel injection and air input module is provided on the input port. The filter components or the filter cylinders have mesh sizes of 0.1 mm-10 mm and are provided in the inner chamber. The ultrasonic transducers are provided in the casing and are connected with the filter screen components or filter cylinders, to drive the filter screen components or filter cylinders to vibrate in ultrasound of high-frequency. Ultrasonic wave is used to generate high-frequency ultrasonic vibration to multiple layers of filter screen components or filter cylinders, so that the oil fuel and air injected into the inner chamber pass through in sequence every filter component or filter cylinder vibrating in high-frequency ultrasound. As such, the mixture of oil fuel and air is intercepted layer by layer and is molecularized for thousands of times, so that the injected liquid oil fuel is crushed to atomized form and fully and uniformly mixed with the air. The required combustion gas mixture is finally output for use.
Said technical solution utilizes high-frequency ultrasound for molecularization to atomize the oil fuel and fully mix the oil fuel with air to obtain the required gas mixture, yet limitations still exist: Firstly, due to its structural design, the volume and efficiency of atomization treatment are limited, and cannot be arbitrarily increased or decreased according to actual needs, and therefore the device cannot be manufactured or sold in a modularized manner. Secondly, as oil fuel is directly injected into the device to be mixed directly with the air, the size of liquid particles in the atomized oil fuel is relatively large and is difficult to be thoroughly and fully mixed with the air. Thirdly, the device does not comprise dynamic self-balancing function and therefore will not be dynamically self-balanced when the device is used in dynamic operating machines. Thus, the device cannot be applied to dynamic operating machines, which affects its range of application. The deficiencies of the said technical solution cannot well meet the needs of production activities.
