NLG heated within a fluid bed dryer is developed in conventional fluidized bed drying and indirectly heated drying technique based on a new type of drying, the heat exchanger immersed in the fluidized dry materials, the materials were heat required for the dehydration tube heat exchanger and by providing fluidization with hot air, with a smaller amount of wind to meet the requirements of the material fluidized drying. . Because most of the heat is provided by a built-in heat exchanger type dryer, hot air is used as the main power of media to ensure the normal fluidized dryer suppliers, so the hot air is greatly reduced compared to conventional fluidized bed dryer needed dryer, power consumption and exhaust heat loss significantly reduced. Sealing fluid bed drying system designed to avoid leakage of the gas within the system to the atmosphere, while avoiding drying air entering the system. Seal design is the premise of strict safety standards dryer manufacturer, by ensuring that the system of internal inert gas (<6% volume, in different conditions, such as starting, stopping and running) implementation. By cooling, the temperature of the recycle gas and water vapor reduced by 85 ℃ 60 ℃. The cooling water is recirculated to the wastewater treatment plant. And after circulating gas cooling and washing back through the fan inside the fluidized bed. Dry particles out of the fluidized bed of inert gas through the loop vibration type cooling bed and the temperature dropped to <40 ℃. How much dryer, dry goods excellent step (certified), dryer step by Changzhou Drying Equipment Co., Ltd .. Drying Equipment Co., Ltd.
