摘要:人类自从发现了电并充分利用了电之后,人们的生活便时时刻刻离不开电。无论家庭生活,还是工厂生产,还是教育,电是不可或缺也是不可替代的。目前发电的方式有多种多样,有煤电、水电、核电、气电、太阳能发电等,其中最为传统的发电形式为煤电。由于人类面临的环境问题越来越严峻,低碳节能的要求越来越高,环保的意识越来越强,本文将针对以煤为主要燃料的火力发电厂的环境治理问题,以达到节能、减排、高效的目的。
关键词:火力发电环境治理低碳节能
Abstract: Since the human beings discovered the electric and made the most use of it, people cannot live a minute without electric. Whenever it is in the family life, or in the production of work force, or in the education, electric is a must and nothing can take the place of it. For the moment, the method of making electric is various, such as coal power generation, hydroelectric power, nuclear power, gas electric, solar power generation and so on. In that the situation we are faced up with is more and more serious, the demand for lowing carbon and energy saving is higher and higher, and the sense of protecting environment is stronger and stronger, this article is about the environment dealing in the firepower which depends mainly on coal, in order to reach the goal of saving energy, letting less, being efficient.
Key words: firepower environment dealing
low carbon and energy saving
一、前言
由于我国人口基数较大,每日的用电需求量相当可观。特别是随着人民物质文化生活水平的飞速提高,用电量急剧增加,有有增无减之趋势。为了满足国内用电的需求量,国内虽然发展了多种新型发电方式,但目前国内占主要地位的发电方式仍然火力发电。下表统计我国目前各种发电装机量所占的比例。由此可见,以燃煤为主要方式的发电模式依然十分盛行。我们十分有必要研究一下火力发电过程中的节能减排以及其工业三废“废水”、“废气”、“废渣”的处理方式,为更好地保护好我们唯一的地球加火添
