净化技术方法
Purification technology and method
废气的处理应从两方面进行:一是针对悬浮粒状污染物的废气除尘;二是针对气态污染物的废气净化气态污染物的控制主要是利用物化性质,如溶解度、吸附饱和度、露点及选择化学反应等的差异,将污染物从废气中分离出来;或者将污染物转化为无害或易于处理的物质。废气净化的基本方法有吸收法、吸附法、冷凝法、催化转化法及燃烧法等。
The treatment of waste gas should be carried out from two aspects: first, dust removal of suspended particulate pollutants; second, the control of purification of gaseous pollutants by gaseous pollutants mainly uses physical and chemical properties, such as solubility, adsorption saturation, dew point and selective chemical reactions, to separate pollutants from the waste gas; or to transform pollutants into harmless or easy-to-treat ones. Matter. The basic methods of waste gas purification include absorption, adsorption, condensation, catalytic conversion and combustion.
大气污染的治理技术概述 大气污染的治理技术是重要的大气环境保护对策措施。洁净燃烧技术是在燃烧过程减少污染物排放与提高燃料利用效率的加工、燃烧、转化和污染排放控制等所有技术的总称。 二氧化硫、氮氧化物和烟(粉)尘是我国主要的大气污染物。减少二氧化硫、氮氧化物和 烟(粉)尘的排放,对于保护和改善大气环境。不仅非常重要。而且十分紧迫。故对二氧化硫、 氮氧化物和烟(粉)尘控制技术做以下概述。
The treatment technology of atmospheric pollution is an important countermeasure of atmospheric environmental protection. Clean combustion technology is a general term for all technologies such as processing, combustion, conversion and pollution emission control to reduce pollutant emissions and improve fuel utilization efficiency in the combustion process. Sulfur dioxide, nitrogen oxides and smoke (powder) dust are the main air pollutants in China. Reducing the emission of sulfur dioxide, nitrogen oxides and smoke (powder) dust will protect and improve the atmospheric environment. Not only is it very important. And it's urgent. Therefore, the control technologies of sulfur dioxide, nitrogen oxides and smoke (powder) dust are summarized below.
洁净燃烧技术
Clean combustion technology
洁净煤燃烧技术是指在燃前煤炭可以通过净化来达到减少污染排放和在煤的燃烧过程中提高效率、减少污染物排放的技术。包括改变燃料性质、改进燃烧方式、调整积烧条件、适当加入添加剂等方法来控制污染物的生成。
Clean coal combustion technology refers to the technology that coal can be purified before combustion to reduce pollution emissions and improve efficiency and reduce pollutant emissions in the process of coal combustion. It includes changing fuel properties, improving combustion mode, adjusting burning conditions and adding additives appropriately to control the formation of pollutants.
高烟囱烟气排放技术
High Chimney Flue Gas Emission Technology
烟气的高烟囱排放就是通过高烟囱把含有污染物的烟气直接排入大气。是污染物向更大的范围和更远的区域扩散、稀释。经过净化达标的烟气通过烟囱排放到大气中。利用大气的作用进一步降低地面空气污染物的浓度。
High chimney exhaust of flue gas is the direct discharge of pollutant-containing flue gas into the atmosphere through high chimney. It is the diffusion and dilution of pollutants to a wider range and farther area. After purification, flue gas that meets the standard is discharged into the atmosphere through chimneys. Utilizing the effect of atmosphere to further reduce the concentration of air pollutants on the ground.
