Problems solved by technology
[0003] When the ultrasonic atomization devices commonly used in these industries are used for the fixation of dangerous substance aerosols, there are the following disadvantages: First, because the viscosity of the atomized liquid for fixing dangerous substance aerosols is higher than that of water at room temperature, resulting in less mist production , or even fogging; secondly, the ultrasonic atomization device does not have a liquid level height adjustment device, resulting in the inability to obtain the best atomization effect; thirdly, due to the single frequency of the transducer device and the driving board, the particle size of the atomized droplets Single, not conducive to the control of aerosol particles of hazardous substances with different particle sizes

The invention relates to an ultrasonic atomization device for controlling aerosol pollution. The ultrasonic atomization device comprises a liquid storing tank (8), an atomizing chamber (5), and a temperature control device. Heat changing equipment (19) and a driving plate (21) are arranged in the atomizing chamber (5), and the liquid storing tank (8) and the atomizing chamber (5) are connected through a delivery pump (14). The temperature control device comprises an electric heating plate (10), a temperature sensor (20) and a temperature controller. The electric heating plate (10) is arranged outside a baseplate of the liquid storing tank (8), the temperature sensor (20) is arranged below the inner portion of the atomizing chamber (5) and the temperature control device is arranged in a control cabinet (2). Interlayer of the side wall of the liquid storing tank (8) is filled with heat-preserving cotton, and a liquid level adjusting device (22) is arranged in the atomizing chamber (5), so that liquid with high viscosity can be atomized effectively; fogdrop can be used for absorbing pollutant and forming a surface coating to prevent pollutant particles from being aerosol so as to control aerosol in the space.
Description
technical field [0001] The invention relates to an ultrasonic atomization device for controlling aerosol pollution, in particular to an ultrasonic atomization device that utilizes a transducing device to atomize the atomized liquid used, and then uses a booster fan to transport the droplets to the area where the aerosol exists The device is mainly used to atomize and capture aerosols of toxic, explosive, radioactive and other dangerous substances. Background technique [0002] At present, the ultrasonic atomization devices commonly used in industry are mostly used in increasing the humidity of indoor air and suppressing and removing various toxic and harmful dust. The atomized medium is water or deionized water. The main components are water tanks with covers. A transducer with a frequency of 1.7MHz and a drive board are installed inside, and a booster fan is installed on the side wall of the water tank. When working, the water mist generated by the booster fan is blown out...
