Ultrasonic enhanced atomization spray haze removal and dust reduction device and method based on electric-high frequency vibration conversion

Abstract

The invention provides an electric and high frequency vibration conversion based ultrasonic reinforcement atomized spraying haze and dust removal device and method and belongs to the technical field of air pollution control. The electric and high frequency vibration conversion based ultrasonic reinforcement atomized spraying haze and dust removal device comprises three function modules and parts of the three function modules, wherein the three function modules comprise a water outlet spray module (3), a stainless steel forced vibration area (5) and a water inlet area (8). The electric and high frequency vibration conversion based ultrasonic reinforcement atomized spraying haze and dust removal device is mainly characterized in that the electric and high frequency vibration energy conversion is implemented through an ultrasonic generator and an ultrasonic transducer; certain pressure of water forms into the high frequency vibration and other micro-action of spray through the water inlet area, a forced vibration chamber and the water outlet spray module to be directly injected and applied to the atmosphere; spray droplets are reinforced through the high frequency vibration and accordingly the probability of the inertia collision with particles is improved, the work through process is reduced, the efficient capture and agglomeration removal is performed on the particles in the atmosphere, and the atmospheric environment is improved. According to the electric and high frequency vibration conversion based ultrasonic reinforcement atomized spraying haze and dust removal device and method, a wet dust removal method is adopted and accordingly the secondary pollution is avoided and meanwhile an open dust removal method is adopted and accordingly the active area is wide, the applicability is high, and the particle capture efficiency is high.

Description

technical field [0001] The invention relates to the field of environmental protection, belongs to the technical field of pollution control equipment, and particularly relates to an ultrasonic enhanced atomization spray haze removal and dust reduction device based on electric-high frequency vibration conversion, which is used for efficient adsorption, agglomeration and settlement of particulate matter in the atmosphere deal with. [0002] The present invention also relates to a method for harmless disposal of atmospheric particle pollution by using the above-mentioned device. Background technique [0003] Atmospheric particulate matter pollution is the primary air pollutant in many cities at home and abroad. Atmospheric particulate matter, especially fine particles, can endanger human health, scatter solar radiation, affect the energy balance of the Earth-atmosphere system, and reduce visibility. The impact of suspended particulate matter on human health is becoming increas...

Problems solved by technology

However, since the main object of dust treatment is dust particles below 150 μm, especially respirable dust particles with a diameter of below 5 μm, the smaller the particle size, the greater the influence of interfacial tension and other factors on it, and its collection efficiency will be lower. The lower it is, the traditional methods of dust suppression will no longer work

[0005] At the same time, due to the complex composition of dust and atmospheric suspended particles, most of them have small particle size, large specific surface area, strong activity, strong hydrophobicity, easy to be accompanied by toxic and harmful substances (such as polycyclic aromatic hydrocarbons, microorganisms, etc.), and the residence time in the atmosphere Long fine suspended particulate matter, the traditional water spray method is extremely difficult to remove and reduce particulate pollutants in the atmosphere
