description The invention relates to a process and a device for continuous ultrasound desulfurization of scrapped lead paste. The process for continuous ultrasound desulfurization of scrapped lead paste comprises the following steps: (1) sodium carbonate or ammonium carbonate is selected as desulfurizing agent, and the desulfurizing agent and the scrapped lead paste are taken according to the mole ratio (1.2 to 2.2:1) of the Na iron or the (NH4)2 iron in the desulfurizing agent to the S iron in the scrapped lead paste; (2) the scrapped lead paste, the desulfurizing agent and water are prepared into flowing pulp with solid-liquid (S/L) weight ratio being equal to 3/5 to 4/5 in a pulping tank; (3) under the condition of ultrasonic wave, the flowing pulp enters a first reaction chamber for heating and stirring from the lower end part in the first reaction chamber, is discharged out from an overflow opening at the upper end of the first reaction chamber, then enters a second reaction chamber for heating and stirring from the
