The utility model discloses a discharge device for liquid sulfur in a sulfur melting kettle. According to the scheme, when the actual temperature is lower than the preset temperature, the channel for discharging flow from the sulfur melting kettle to the flow discharging channel is cut off through the first stop valve, and when the first stop valve generates the closing action, the second stop valve is opened, so that steam introduced from the outside is injected to the flow discharging channel. Therefore, through the cooperation of the first stop valve and the second stop valve, the discharge of the liquid sulfur can be accurately controlled, and the upper-layer salt liquid of the sulfur melting kettle is continuously discharged to the lower-part liquid sulfur tank after the sulfur liquid at the bottom layer of the sulfur melting kettle is emptied as little as possible. Meanwhile, the automatic purging device prevents residual salt liquid and sulfur liquid from blocking the pipeline when the steam is unstabl
