The Choice Of Heat Carrier Is Very Important For The Rotary Dryer

The heat carrier has a great role in the working process of the drum dryer. Different materials conform to different heat carriers,Rotary Dryer so the choice of heat carrier is also very important. If the solid materials being processed are not afraid of high temperature,Rotary Dryer and can be allowed to be slightly polluted during the process of disposal,Rotary Dryer a hot blast stove or flue gas can be used as a heat carrier, and a higher volume evaporation rate and thermal efficiency can be achieved. For example,Rotary Dryer regarding the dryness of materials with high water content at the inlet,Rotary Dryer when the gas inlet temperature is 300 degrees, the volume evaporation rate of the dryer is 5kg/M3/h,Rotary Dryer and the thermal efficiency is 30%-50%; if the gas inlet temperature is 500 degrees, then The volume evaporation rate is 35kg/M3/h; the thermal efficiency is 50%-70%. Therefore,Rotary Dryer the rotary drum dryer bucket for disposing of ore, sand, coal,Rotary Dryer calcium persulfate and other materials has an extinguishing furnace that directly generates flue gas. The gas fuel can be coal, oil, natural gas,Rotary Dryer liquefied gas, etc.

If the materials to be handled are not allowed to be polluted and the required temperature is high,Rotary Dryer the new product gas generator can be used as a heat carrier. This product is energy-saving and environmentally friendly,Rotary Dryer and has high thermal efficiency. If the dry object is not allowed to be contaminated and is not allowed to be diluted with air,Rotary Dryer heat should be introduced through the wall of the drum dryer. At this time, the drum is loaded into the brick room,Rotary Dryer and the outside of the drum is ventilated with flue gas. The external heat exchangers in the middle of the carrier,Rotary Dryer such as the middle pipe or column tube, casing, etc., shall use metal wall heat transfer. The heat carrier can be flue gas,Rotary Dryer water vapor or electric heating. In the dry material, only the clean gas passes through the evaporated water.
