摘要
[目的]煤尘污染主要发生在燃煤转运点处,传统转运设备及除尘技术无法有效控制。文章旨在研究当前几种新型清洁转运技术,以从根本上控制煤尘污染、满足环保标准要求。[方法]在总结污染源及当前技术缺陷的基础上,针对干雾抑尘、IFT(3-DEM)、无动力除尘导料槽等清洁转运新技术的原理、特点进行分析,并结合典型实例进行技术经济比较。[结果]研究表明:清洁转运新技术可靠性高、应用范围广,能有效控制燃煤转运过程中煤尘污染,实际效果满足环保标准,具有良好的社会效益和经济效益。[结论]清洁转运新技术能解决煤尘污染面临的环保问题,推荐在项目中应用。
[Introduction]The coal dust pollution mainly occurs at transfer point, and have not been effectively controlled by the traditional equipments and dust removal technologies. This paper aims to study several new clean transport technologies to fundamentally control coal dust pollution and meet environmental standards. [Method]On the basis of summarizing the origin of coal dust pollution and current technical defects, combined with typical examples, the principles and characteristics of new technologies,which were dry mist dust suppression, IFT(3-DEM), non-power dust removal groove and so on, were analyzed and carried out technical and economic comparisons. [Result]Research shows that the new technologies have high reliability and wide application range, and can effectively control coal dust pollution during coal transportation. The actual effect meets environmental protection standards and has good social and economic benefits. [Conclusion]New clean transport technologies can solve the environmental problems faced by coal dust pollution, it is recommended to apply in projects.
