Embodiment Construction

[0020] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0021] See figure 1 Said, a wet type fine particle capture device of the present invention includes an ultrasonic atomizer and a Venturi dust collector 100. The ultrasonic atomizer is in communication with the Venturi dust collector 100, wherein the ultrasonic atomizer is used to transform ordinary water droplets into In order to transport the water mist to the Venturi dust collector 100, the Venturi dust collector 100 uses the water mist to wash the waste gas to be treated to achieve the purification treatment of the gas to be treated. Compared with the traditional Venturi dust collector 100, the present invention The contact between the water mist and the gas to be treated is adopted, which increases the cont...

Abstract

The invention provides a wet-type fine particles capturing device. The wet-type fine particles capturing device comprises an ultrasonic vapourizer and a venturi deduster, the venturi deduster comprises an inner tube and an outer tube, the inner tube is sleeved in the outer tube and forms a backflow chamber with the outer tube, a water inlet and an air inlet are arranged on the outer tube, an output terminal of the ultrasonic vapourizer, an output terminal of the ultrasonic vapourizer is connected with the water inlet, an air outlet is arranged on the inner tube, the air outlet is arranged at the bottom of the backflow chamber, and a water outlet is arranged at the bottom of the backflow chamber. By employing the ultrasonic vapourizer, water drops are changed to water mist, a mode that gasis introduced from up to down and water mist is introduced from down to up is employed, the water mist and to-be-processed gas form convection current, by using a principle of large gravity of the water mist and small gravity of gas, backflow is formed between the water mist and gas, so that contact time of the water mist and the gas is longer, the fine particles capturing rate of the venturi deduster is effectively increased, the contact time of the gas and the water mist is guaranteed, and the purifying effect is increased.

Description

Technical field [0001] The invention relates to the technical field of air purification, in particular to a wet type fine particle capture device. Background technique [0002] Organic solvents widely used in life and production are easily volatilized into gases at room temperature, so they are also called Volatile Organic Compounds (VOCs). Most VOCs are toxic to the human body and must be treated; in addition, they are caused by air Quality monitoring data show that the ozone produced by the reaction of odor precursors such as VOCs and NOx with light has replaced suspended particulates as the main pollutant affecting the air pollution index (PS1). Therefore, strengthening the control of VOCs emissions is to improve air quality. Therefore, environmental protection departments have successively formulated VOCs emission standards for various industries (including semiconductor, optoelectronics, automobile coating, PU leather, tape and other industries). [0003] In addition, due to ...
