【摘要】：我国煤炭产量居世界第一,可探明储量居世界第二。因此煤炭在我国能源结构中处于绝对主体地位短期不会改变。煤炭燃烧产生的烟尘、SO2等污染物是造成雾霾、酸雨等大气污染的主要原因之一。我国也越来越重视大气污染的治理问题,控制热电厂污染物的排放对改善大气环境具有十分重要的作用。本文概括了烟气除尘脱硫技术的现状,针对山东中华发电有限公司石横发电厂一、二期4 X 315MW机组除尘脱硫系统,寻求最佳处理方案使烟气排放达标。根据石横发电厂的具体情况,本文选择合适的除尘脱硫方法,设计高效的工程技术方案,采用先进的控制手段,提高烟气排放的质量。经过分析比较,脱硫采用旋流喷雾烟气脱硫技术,除尘采用离心式管束除尘技术,在原有设备基础上进行改造,并进行改造结果检验,实现了脱硫除尘一体化超低排放。本文的研究对火电厂除尘脱硫系统建设、运营提供了重要的理论依据与实践经验,能够产生较好的经济、环境和社会效益。本文的研究对越来越严格的新标准实施过程中,对热电厂烟气达标排放的方法做出了积极探索,起到了表率作用,对于推动社会经济协调发展具有非常重要的意义。
[Abstract]:China ranks first in coal production and second in proven reserves in the world. Therefore, coal in China's energy structure in the absolute dominant position will not change in the short term. Pollutants such as soot and sulfur dioxide produced by coal combustion are one of the main causes of air pollution such as haze acid rain and so on. More and more attention has been paid to the treatment of air pollution in China. Controlling the emission of pollutants from thermal power plants plays an important role in improving the atmospheric environment. The present situation of flue gas dust removal and desulfurization technology is summarized in this paper. Aiming at the dust removal and desulfurization system of 4 X 315MW unit in Shiheng Power Plant of Shandong Zhonghua Power Generation Co., Ltd., the best treatment scheme is sought to make the flue gas discharge up to standard. According to the specific situation of Shiheng Power Plant, this paper selects the appropriate method of dust removal and desulfurization, designs the efficient engineering technical scheme, and adopts advanced control measures to improve the quality of flue gas emission. Through analysis and comparison, desulphurization adopts swirl spray flue gas desulphurization technology, dust collection technology adopts centrifugal tube bundle dust removal technology, on the basis of the original equipment, and carries on the transformation result inspection, realizes the desulphurization and dust collection integration ultra low discharge. The research in this paper provides important theoretical basis and practical experience for the construction and operation of dust removal and desulfurization system in thermal power plants, and can produce better economic, environmental and social benefits. In the process of implementing the more and more strict new standards, the research in this paper has made an active exploration on the methods of flue gas emission reaching the standard in thermal power plants, which has played an exemplary role in promoting the coordinated development of social economy.
