Control Technology of PM_(2.5) in Coal-Fired Power Plant and Experiment on dedusting performance of Typical filters to PM_(2.5)

摘要

People pay more and more attention on the fine particle pollution in the air with the improvement of environmental awareness. Coal-fired power plant is an important source of the fine particle emissions. The principles of three dedusting methods applied in coal-fired power plants were explained, which were electrostatic precipitator, bag deduster and composite electrostatic-bag precipitator. In addition, PM_(2.5) removal efficiency of three dedusting methods was analyzed and discussed based on the test results. The experiment, with the "AFC-131"test rig, was carried out on dedusting performance of typical filters, to study the effect of pressure drop of filters on the emission characteristics of PPS filter material of different processing technology and posttreatment.
