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

Embodiment Construction
[0021] The present invention will be described below in conjunction with the accompanying drawings and specific embodiments.
[0022] An ultrasonic atomization device for controlling aerosol pollution, such as Figure 1-4 As shown, it includes a liquid storage tank 8 and an atomization chamber 5. The booster fan 4 is arranged on the atomization chamber 5 through a screw 3, and the atomization chamber 5 is fixed on the liquid storage tank 8 through a screw 9. Around the liquid storage tank 8 The side wall is provided with an interlayer, and the interlayer is filled with 15-20mm thermal insulation cotton, so that the liquid storage tank in the present invention has a good thermal insulation effect. A mist collecting cover 6 is arranged above the top plate of the atomization chamber 5, and a transducing device 19 and a driving plate 21 are arranged in the atomizing chamber 5, the transducing device 19 is installed on the bottom of the atomizing chamber 5, and the driving plate 21...

The invention relates to an ultrasonic atomization device for controlling aerosol pollution, which comprises a liquid storage tank (8), an atomization chamber (5), and a transducing device (19) and a drive plate ( 21), the liquid storage tank (8) is connected with the atomization chamber (5) through the delivery pump (14), the ultrasonic atomization device also includes a temperature control device, the temperature control device includes an electric heating plate (10), a temperature sensor (20) and the temperature controller, the electric heating plate (10) is installed outside the bottom plate of the liquid storage tank (8), the temperature sensor (20) is installed under the interior of the atomization chamber (5), and the temperature controller is installed in the control box ( 2), the interlayer of the side wall of the liquid storage tank (8) of the present invention is filled with thermal insulation cotton, and a liquid level adjustment device (22) is installed in the atomization chamber (5), so it can effectively atomize liquids with higher viscosity. The droplets trap pollutants and form a surface coating that prevents the pollutant particles from forming aerosols, thereby controlling aerosols 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...
