This utility model discloses a spray desulfurization device and a shaking furnace for use in a shaking furnace. The desulfurization device includes a spray gun and a mixing hopper. The spray gun is connected to the mixing hopper through a spray
pipe. The spray gun includes a spray section and a connecting section. The top end of the spray section is connected to the bottom end of the connecting section, and a
nozzle is connected to the bottom end of the spray section. A rack is provided on the connecting section, and a drive gear is meshed on the rack. The drive gear is connected to a first
drive motor. An annular gas distribution
pipe is provided inside the mixing hopper, and a gasification
pipe is provided on the annular gas distribution pipe. The annular gas distribution pipe is connected to an external gas source through a
gas supply pipe. A feed pipe is provided on the mixing hopper. In this utility model, after the desulfurizing agent is put into the mixing hopper, the carrier gas is sprayed out from the gasification pipe, so that the desulfurizing agent is fluidized for spraying and feeding, improving the uniformity of feeding. During feeding, the rack is driven to rise and fall by the first
drive motor, so that the desulfurizing agent is sprayed and released at different depths in the shaking furnace, expanding the reaction area and avoiding the desulfurizing agent being concentrated only on the surface of the shaking furnace or at a fixed depth, thereby improving the desulfurization efficiency.
