Ultrasonic atomization desulfurizer for spray tower

Technical Field

The utility model belongs to the technical field of the desulfurizer, concretely relates to spray column ultrasonic atomization desulfurizer.

Background

With the development of economy in China, environmental pollution caused by energy consumption is more and more serious. Among them, the damage of haze, acid rain, greenhouse effect and ozone layer has become four major killers harmful to the survival of people. The harmful substances such as smoke dust, sulfur dioxide, nitrogen oxide and the like contained in the coal-fired flue gas are main sources of air pollution, acid rain and greenhouse effect. China has abundant coal reserves, and the annual output exceeds 10 hundred million tons. The energy obtained by coal burning in China reaches over 75 percent of the total energy, and the energy structure cannot be changed in recent years. Meanwhile, the sulfur dioxide and nitrogen oxide discharged from the coal-fired flue gas account for 90 percent of the total national discharge. Therefore, the desulfurization and denitration of the coal-fired flue gas are a very slow task in China. The environmental protection department, the national development and improvement committee and the energy agency jointly release the 'comprehensive implementation of the ultra-low emission and energy-saving improvement working scheme' of the coal-fired power plant at the end of 2015, the indexes of electric coal-fired coal per degree are forcibly reduced from 286 grams to 206 grams, and the heat exchange efficiency and the flue gas emission standard of the coal-fired power plant are forcibly improved. The core links of flue gas treatment are desulfurization, denitration and deacidification.

The currently used neutralization solutions are lime slurry, urea solution and caustic soda flake solution, and these solutions are sprayed to the flue gas to be treated for neutralization reaction. Current spray techniques can be classified into mechanical atomization, mechanical + media atomization, bubble atomization, and the like, depending on the atomization mode.

On the basis, the continuous development of more efficient, more economical and more applicable atomization technology becomes the key point of atomization research, and atomization by using the ultrasonic technology is one of the technologies. In the end of the 80 s and early 90 s of the 20 th century, acoustic atomization has attracted attention as a new atomization technology. The research result shows that: the acoustic atomization performance is generally superior to that of other types of atomizers, the atomization particle size is small, and the uniformity of atomized liquid drops is good. Thus, with an acoustic atomizer, the medium atomization efficiency can be improved.
