Introduction to dry desulfurization:
Dry flue gas desulfurization, also known as dry flue gas desulfurization, refers to the use of powdered or granular absorbents, adsorbents, or catalysts to remove gases containing sulfides from flue gas.
Definition of dry flue gas desulfurization: CaCO3 injected into the furnace is calcined at high temperature and decomposed into CaO, which reacts with SO2 in the flue gas to produce calcium sulfate; The use of electron beam irradiation or activated carbon adsorption to convert SO2 into ammonium sulfate or sulfuric acid is collectively referred to as dry flue gas desulfurization technology.
Its advantages are simple process, no sewage or acid treatment problems, low energy consumption, especially the high temperature of purified flue gas, which is conducive to chimney exhaust diffusion and does not produce "white smoke" phenomenon. The purified flue gas does not require secondary heating and has low corrosiveness.
