Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a high-efficiency flue gas spray drying desulfurization device. Background technique [0002] Environmental pollution will cause direct damage and impact on the ecological system, such as desertification and forest destruction, and it will also cause indirect harm to the ecological system and human society. Sometimes the harm caused by this indirect environmental effect is greater than the direct harm caused at that time. Also harder to remove. With the intensification of pollution and the improvement of people's environmental awareness, crowd disputes and conflicts caused by pollution are increasing year by year. Environmental protection equipment refers to mechanical products, structures and systems manufactured and constructed by production units or construction installation units for controlling environmental pollution and improving environmental quality. Environmental gove...
