Steam sterilization device for loose poria engineering bacterium bag

The utility model relates to a sterilization device, which comprises an atmospheric pressure steam boiler, a steam delivery pipeline and a sterilization cabinet which are connected sequentially. The sterilization device is characterized in that the smoke exhausting chimney of the atmospheric pressure steam boiler is provided with a heater, the heater is connected with the atmospheric pressure steam boiler and the sterilization cabinet through the steam delivery pipeline, the sterilization cabinet is connected with a cooling water storage tank through a cooling pipeline, the cooling water storage tank is connected with a safety disposal tank through a pipeline, and the safety disposal tank is connected with a water discharging pipeline. With the heater on the atmospheric pressure steam boiler, the rate of utilization of heat energy can be increased, emission of SO2 can be reduced, SO2-containingwater vapor can be recycled through cooling, and pollution-free water can be produced through chemical reaction and t
