The present application relates to desulfurization technical field, specifically to a kind of under-liquid
slurry supply desulfurization absorption
tower and desulfurization method thereof, including
tower body, spray layer, oxidizing air
pipe,
slurry circulating pump,
gypsum discharge pump and
agitator, further including a under-liquid
slurry supply pipeline, slurry
pool is equipped in the
tower body, slurry supply outlet is equipped on the under-liquid slurry supply pipeline, the slurry supply outlet is arranged on the lateral wall of slurry
pool area, the slurry supply outlet position is higher than the effective stirring depth of the
agitator paddle, but lower than the slurry
pool liquid level position of traditional under-liquid slurry supply.The present application makes that
gypsum quality is radically improved,
system efficiency and energy saving are remarkable, limestone
utilization rate approaches theoretical optimum value,
system adaptability is strong, investment potential is big.
