Electron Beam Desulfurization Of Key Technologies And Processes

The dissertation is based on some theoretical researches and experimental investigations of electron beam process on flue gas desulphurization and denitration, of which electron beam transport, radiation chamber, by-product collection and process technology are included. On the scale of industrial application, the electron beam transport efficiency and radiation chamber design method has been figured out mainly based on the simulation of EGS4 software of Monte Carlo method. On the basis of theoretical analysis, an electrostatic precipitator technology for collecting by-products has been developed and verified by the investigation on three pilot scale collectors. The investigations show that the erected pilot plant is of better property. Based on the pilot plant investigation, some main elements influencing the removal of SO2 NOx, such as flue gas temperature, electron beam dose etc. have been investigated, and their working patterns have also been made certain of. The basic physical and chemical principle, technology and equipment of electron beam process has also been reviewed and summarized in the dissertation.
