电厂烟囱高度确定的技术方法

烟囱不仅是电厂生产工艺上为获得一定抽力的排气筒,更重要的是控制大气污染保护环境的重要设施.通过研究有关电厂烟囱高度合理性方法,指出影响污染物落地浓度的主要影响因素,并从气象和环境空气影响角度对不同高度烟囱合理性进行检验.本文实例分析结果表明,烟囱高度要以适合当地气象和环境空气质量实际情况为原则,最大限度地减轻污染物落地浓度对当地造成的不利影响,并从技术、经济的合理性方面进行分析和论证,这对减轻污染和减少资金投入以及对于指导环境空气影响评价工作具有重要意义.

The Technique of Ascertaining the Height of Electricity Factory Chimney

Chimney is not only a tail pipe to obtain suction in electricity factory, but also an important equipment of controlling air pollution and protecting the environment. By research for rational technique on the height of electricity factory chimney, the article pointed out the main effect factor of contamination falling thickness, and tested the rationality of different chimney height from weather and air influence aspect, the example in the article indicated that chimney height should adapt to local weather and air quality, alleviate the adverse influence of contamination falling thickness, and analyze it in the aspect of technique and economy rationality. This has important meaning of reducing pollution and fund devotion and instructing air environment influence appraisal.
