SDS (sodium dodecyl sulfate) dry desulfurization concentrated mother liquor recycling process capable of recycling sodium bicarbonate

The invention provides an SDS dry desulfurization concentrated mother liquor recycling process capable of recycling sodium bicarbonate, which comprises the following steps: pyrolyzing, dissolving and filtering desulfurization slag, adding acetic acid for neutralization, and performing evaporative crystallization separation to obtain sodium bicarbonate salt and centrifugal mother liquor; and the generated centrifugal mother liquor is high in concentration and mainly contains sodium sulfate, sodium bicarbonate and sodium acetate. The centrifugal mother liquor enters an acidification reaction kettle, sulfuric acid is added to remove sodium bicarbonate, sodium acetate is converted into acetic acid, acetic acid is recycled through vacuum condensation, a liquid phase passes through a solid-liquid separation device to obtain a sodium sulfate crude product and a mother liquor, the mother liquor flows back to the acidification reaction kettle, the sodium sulfate crude product is detected, if the pollutant concentratio
