The Energy-saving Effects of Coal Slurry Dryer

Slime dryer that have the features of energy saving, lower loss is the best product that cater to the trend of the times,and welcomed by the majority of users, our company are constantly research this aspects to let the slime dryer energy becomes more efficient, according to our years production dryer experience,we have found a good way to let the slime dryer more energy efficient, now I summed up here for you to share: The two methods that maximum realize the energy-saving effects :
First , Maximum use the heat to conduct the drying operation, this is a the  goal every dryer production enterprise pursue , four methods can achieve energy saving of slime dryer, which is one of the various links in the drying process in reducing heat loss. When heat certain circumstances, to minimize the heat loss, so that the thermal energy for the drying operation, again to improve the efficiency of drying. Generally, the heat loss of the drying machine does not exceed 10%, and the insulation suitable medium-sized production device, heat loss is about 5%. Therefore, good drying system insulation work, but is not thicker, the better the insulation layer, should determine an optimum insulation thickness. Generally use the blower and induced draft fan in order to prevent the leakage of the drying system, used in tandem, to make reasonable adjustments to state operation of the system is zero pressure, to avoid convection dryer drying medium leakage or ambient air leaking into drying The decline in the efficiency of the machine hot.
Second, reduce the evaporation load of the dryer is the second method to improve the drying efficiency, before the material enters the dryer, the pre-dehydration treatment by filtration, centrifugation or the evaporator evaporation, etc., the increased mass of the solid content, reduce the evaporation of the dryer load, which is one of the most effective energy-saving method of drying equipment. For liquid materials (such as solutions, suspensions, emulsions, etc.), before drying pretreatment can also be energy saving, is the use of water was heated in a convection dryer for material utilization is air sensible heat, while preheating refers to the utilizaiton of the steam or heat, and so on. For spray drying, the preheating of the feed solution is also beneficial to the atomization.
