PM_2.5细颗粒物捕集设备研究应用现状

【摘要】 PM2.5细颗粒物因其粒径小、吸附能力强、环境影响大,同时捕集困难而成为备受世界各国关注的大气环境问题,我国也将PM2.5作为空气质量标准的一项新指标。结合现有的标准和技术条件,对PM2.5细颗粒物有高效捕集效果的新型袋式除尘器、湿式电除尘器、电凝并器、电—袋混合式除尘器,特别是无机膜过滤器的特点、研究应用现状及存在问题进行了概述。更多还原

【Abstract】 The treatment for PM2.5 particle matter has been paid more and more attention around world for its small size, strong adsorption ability,great effect on air condition and difficulty to be trapped. Consequently,PM2.5 discharge concentration has been used as a new index of air quality standards. Based on the existing standards and technical level,the characteristics,research and applications,problems for current PM2.5 capturing devices were reviewed generally,including:new type bag dust collector,wet electric dust collector,electric coagulation and electric- bag of hybrid filter device,as well inorganic membrane filter in particular.更多还原
