The present application belongs to the technical field of industrial
flue gas purification and
energy recovery, and discloses a flash tank for deep degassing of desulfurization
slurry, wherein an exhaust port, a
demister, a spraying layer, a baffle
assembly, a flow stabilizing element and a
slurry outlet are sequentially arranged in the tank body from top to bottom; the baffle
assembly comprises at least two baffles, and the receiving surface of the baffle is downwardly inclined; a plurality of guide partitions are arranged side by side on the receiving surface of the baffle, and the guide partitions extend along the inclined direction of the baffle to divide the receiving surface into a plurality of
slurry flow channels; the flow stabilizing element is installed on the upper part of the slurry outlet to stabilize the desulfurization slurry and eliminate vortex.
