Abstract
This utility model belongs to the technical field of coal desulfurization equipment, and relates to a reaction device based on coal biological desulfurization, including an auger screw conveyor and a reaction tank. The tubular shell of the auger screw conveyor has a feed inlet at the right end and a discharge outlet at the left end. The auger screw conveyor is installed inside the reaction tank and is inclined from left to right. The feed inlet is immersed in the microbial liquid in the reaction tank, and a feed funnel is installed at the feed inlet. Multiple water inlet channels are opened on the right side wall of the tubular shell. This reaction device can be used for coal biological desulfurization. Coal enters the tubular shell through the feed inlet and is soaked in the microbial liquid. The screw blades of the auger screw conveyor can drive the coal to rise in a spiral. The screw blades have a stirring effect on the coal soaked in the microbial liquid, so that the microorganisms and coal are fully mixed, which can improve the desulfurization efficiency and speed. The screw blades continuously transport coal between the feed inlet and the discharge outlet, which can realize a production line desulfurization operation.
