Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection systems, in particular to an improvement of liquid discharge system equipment of a desulfurization island. Background Art

[0002] Existing desulfurization island tank drainage, cooling water and flushing water discharge from each pump, and filtrate discharge from the vacuum belt filter all utilize open drains. This drainage process is accompanied by the alkaline slurry. Different desulfurization slurries emit varying amounts of alkaline substances, which are released into the air as the water evaporates. Alkaline solutions release gases or produce corrosive solutions, which can be harmful to skin and eyes and corrosive to equipment and other instruments. Wastewater discharged from the desulfurization tower produces hydrogen sulfide and sulfurous acid, which are harmful to internal organs, eyes, and skin. Furthermore, the high temperatures of both the wastewater and slurry from the desulfurization tower accelerate water evaporation, leading to the evaporation of more harmful substances and water.
