Problems solved by technology

[0004] However, the existing ultrasonic atomization devices are only suitable for atomizing single-phase solutions such as water and alcohol.
And when there is no load (no liquid), the low-efficiency high-frequency oscillating transducer will instantly heat up to above 200°C, causing the transducer to burn out, so this kind of ultrasonic atomization device must be completely immersed in the liquid to work, so that The atomization device usually requires a water storage tank and can only be atomized from bottom to top. Only by applying a certain diversion gas can the liquid mist be blown to other directions. This defect also makes this atomization device in many are very limited in practical applications
[0005] Moreover, the vibration frequency of the existing ultrasonic atomizing nozzle is generally higher than 40KHz, and the heat generated by the transducer is relatively high during operation. Most of the transducers do not have a good heat dissipation function. When working continuously, it is easy to cause the transducer Damaged by overheating, the transducer needs to be replaced frequently to continue working, which delays working time and directly affects work efficiency

Abstract

The invention discloses an ultrasonic atomization device used for suspension liquid. The ultrasonic atomization device comprises a transducer shell, a transducer, an atomization tool head, a liquid spraying ring, an air inlet hole, an air outlet hole, a liquid inlet and liquid outlet holes. The transducer shell wraps the transducer. The transducer is connected with an ultrasonic power supply through a wire interface located on the top of the transducer shell. The atomization tool head is connected with the transducer. The transducer is connected with the liquid spraying ring in a clamping and buckling mode. The air outlet hole is formed in the bottom of the transducer shell. A gap between the transducer shell and the transducer is filled with heat conducting glue. The air inlet hole is formed in the upper portion of the transducer shell. Compressed air enters the interior of the transducer shell through the air inlet hole, and flows rapidly in the transducer shell cavity. According to the ultrasonic atomization device, the atomization ability and atomization efficiency of the ultrasonic atomization device are improved, the atomization of the suspension liquid and a solution is achieved, in addition, the device is not limited by liquid storage and the liquid level and can work continuously, and the ultrasonic atomization device has wide application prospects in the field of thermal power plant flue gas desulfurization and denitration systems.

Description

technical field [0001] The invention relates to a liquid spraying device, in particular to an ultrasonic atomizing device for atomizing suspensions with high viscosity or containing tiny solid particles, especially suitable for flue gas desulfurization and denitrification systems in thermal power plants , belonging to the field of ultrasonic atomization. Background technique [0002] Sulfur dioxide is a gaseous pollutant with a large amount and a wide range of influence among the current air pollutants. With the rapid development of human society, the demand for energy continues unabated. This is doomed that the problem of environmental pollution will become increasingly severe, and power plants consume a lot of coal and produce a lot of sulfur dioxide, so desulfurization of power plants is an important means of protecting the environment. At present, most power plants use wet desulfurization process. The slurry produced in this process is sprayed out through the atomizin...
