AI Technical Summary
Existing coal-fired power plants rely on chemical agents during flue gas water extraction and tempering, resulting in high costs and environmental pollution. The calcium carbonate filler needs to be replaced regularly, and the calcium sulfate waste cannot be effectively treated.
A system for improving water and tempering of flue gas and improving quality of high alkali coal is designed. After the flue gas is condensed through a condenser, it is passed into the immersion tower for neutralization and reaction regulating, removing alkaline earth metals from the high alkali coal, and removing acidic wastewater from the coal material in the leaching tower to achieve chemical-free treatment.
The neutralization reaction and tempering of flue gas water extraction is achieved, operating costs and environmental pollution are reduced, chemical agents are used and calcium carbonate filler replacement is avoided, and acidic wastewater in coal is effectively treated, improving the quality of coal.
