基于等离子体技术的超声波除尘方法研究

为了解决PM10/PM2.5沉降的问题,探讨了等离子体条件下进行超声波除尘的原理,提出了一种结合等离子体技术的超声波除尘方法。设计了一种基于光散射法的悬浮颗粒物浓度检测方法,配备等离子体发生器和超声波发生器的空气处理室,以及用于悬浮颗粒物浓度的采集、存储和数据分析的系统。作者按悬浮颗粒物自然沉降、超声波作用沉降、等离子体作用沉降及等离于体和超声波共同作用沉降等4种条件对悬浮颗粒物的沉降速率进行了对比实验,实验结果表明,采用等离子体和超声波复合式除尘方法可以有效地实现PM10/PM2.5的快速沉降。

Research on ultrasonic dust removal method based on plasma technology

In order to solve the problem of settlement of PM10/PM2.5,the working principle of ultrasonic dust removal under the condition of plasma was discussed and An ultrasonic dust removal method combined with plasma technology was proposed. In this paper, a method of suspended particulate matter concentration detection based on light scattering method was designed. An air treatment room with a plasma generator and ultrasonic generator was structured, and an experimental system used for collecting the concentration information of suspended particulate matter as well as storing and analyzing experimental data was built. Four contrast experiments were done to compare the suspended particles settling rates of in natural state, with ultrasonic only, with plasma only and with ultrasonic and plasma both. The results show that the compound dust removal method both with ultrasonic and plasma can settle the PM10/PM2.5 rapidly and efficiently.
