火电厂烟气除尘问题研究

摘要随着经济的发展，我国电能需求量也在逐年攀升，随之火电厂的任务也越来越重，虽然火电的发展带来了经济的提升，但也带来了负面的影响，火电厂燃烧的煤炭等等产生了巨大的烟气粉尘污染，是PM2。5的主要来源之一，使得空气受到了污染，气候变暖，雾霾情况越来越严重，这一问题得到了国家相关部门的深刻关注。78206

研究烟气除尘问题对于环境保护，迎合国家相关政策，建设绿色城市有着重要的意义，控制污染物的排放，控制PM2。5，可以有效减轻雾霾问题，本文着重研究了各种烟气除尘相关技术，综合了各种技术对我国烟气除尘相关问题做了一个详细的统计，以及对我国烟气除尘问题的展望。

The study of coal-fired power plant flue gas dust removal issue

Abstract With the development of economy, China's electricity demand is also rising year by year, with the task of coal-fired power plants is becoming more and more heavy, although the development of thermal power brought the ascension of the economy, but also brought negative impact, coal-fired power plants burning coal and so on has a huge smoke dust pollution, is one of the major source of PM2。5 air polluted, climate warming, haze is more and more serious, this problem is the deep concern of the government authority。

Research of flue gas dust removal problem for environmental protection, building a green city has an important meaning, control the emissions of pollutants, control of PM2。5, can effectively reduce the smog problem。 This article introduces the various flue gas dust removal technology, and the analysis of the effect of new technology in the application of electrostatic precipitator。

There are 9 figures, 8 tables and 21 references in this paper。

Key Words: thermal power plants flue gas dust removal environment protection
