Abstract

The invention discloses a concentrated seawater re-concentration treatment and smoke gas desulfurization device, and belongs to the field of concentrated seawater treatment and smoke gas desulfurization treatment. The concentrated seawater re-concentration treatment and smoke gas desulfurization device comprises a smoke gas system, a concentrated seawater supply system and a smoke tower, wherein the smoke tower comprises a tower body; a spraying device, a desulfurization region, a concentrated seawater evaporation region and a salt particle / salt slurry sedimentation region are sequentially arranged in an inner cavity of the tower body from top to bottom; the desulfurization region, the concentrated seawater evaporation region and the salt particle / salt slurry sedimentation region are communicated; a smoke gas inlet is formed under one side of the tower body, and communicates with the concentrated sea water evaporation region; a concentrated seawater inlet is arranged above one side of the tower body; a spraying device communicates with the concentrated seawater inlet. The device provided by the invention has the advantages that the equipment is simple; the addition of additional chemical reagents is not needed; the desulfurization treatment on the smoke gas and the concentrated seawater re-concentration treatment on the smoke gas can be realized; the defects of much equipment, high investment, high operation cost and great equipment overhaul maintenance workload of the existing smoke gas desulfurization and concentrated seawater treatment system are effectively overcome.

Description

technical field [0001] The invention relates to the field of concentrated seawater treatment and flue gas desulfurization treatment, in particular to a concentrated seawater re-concentration treatment and flue gas desulfurization device. Background technique [0002] Seawater desalination technology, as a fresh water source increasing technology, can provide qualified fresh water and play an important role in solving the shortage of fresh water resources. At present, large-scale commercial seawater desalination technologies, including reverse osmosis, multi-effect evaporation and multi-stage flash evaporation, generally have a freshwater recovery rate of 40%-55%, which inevitably produces a large amount of concentrated seawater while providing freshwater. At present, the main methods for processing concentrated seawater in seawater desalination plants are: directly or mixing it with raw seawater and then discharging it back into the sea, and introducing concentrated seawater...
