摘要/Abstract

摘要： 基于传统湿式除尘器在矿山井下应用中存在的除尘效率较低、阻力大等问题，研发了一种适合矿山井下使用的移动式矿用湿式振弦旋流除尘器。介绍了该除尘装置的结构、工作原理和除尘机理，并对该除尘装置的除尘效率和阻力特性进行了实验研究。除尘机理分析表明：该除尘器有机地利用了喷雾降尘理论、振弦栅捕尘理论与旋流除尘理论，借助水雾、水滴、水膜、旋流4级除尘技术，使雾滴与含尘气流接触面积大、接触时间长、捕尘效率高。试验研究表明：综合考虑除尘效率和阻力因素，该除尘器运行时的最佳风速为10～12 m/s，对总粉尘的除尘效率大于98%，对呼吸性粉尘的除尘效率大于96%，阻力小于700 Pa，在矿山井下除尘系统具有广泛的应用前景。

Abstract: Based on the traditional wet dust collector with the shortcomings of low dust removal efficiency and high resistance in the application of dust removal system for underground mine， a mobile wet vibrating string cyclone dust collector， which is well adapted for dust removal system of mine， was researched. The structural， working principle and dust collection mechanism of the dust removal device were introduced， and experimental research on its dust removal efficiency and resistance characteristics were carried out. The analysis of dust removal mechanism showed that the dust collector has made use of the theory of spray and dust suppression， the theory of vibrating string trapping and the theory of swirling dust removal. Four stage dust removal technology including water mist， water droplet， water film and swirling makes the contact area between droplet and dust airflow wide， the contact time long， and the efficiency of dust collection high. The experimental results showed that considering the factors of dust removal efficiency and resistance， the optimal wind speed is 10~12 m/s， which realized the total dust removal efficiency more than 98%， the respirable dust removal efficiency more than 96%， and the resistance less than 700 Pa. The dust removal system has broad application prospects in underground mine.
