概述
废热空气或换热空气进入转筒干燥器内，在通道中直接与湿固废传热传质，配套专用破碎装置(特殊结构设计)，使固废中的水分快速蒸发，固废颗粒较小的随气体一起由外通道排出干燥器收集，而较大的固废颗粒在干燥器中停留的时间较长，直至干化完成。部分废气抽出，经除臭器处理达到大气排放标准后(或经水沫除尘降温后)排入大气中。
Waste hot air or heat exchange air enters the rotary drum dryer,ａnd directly transfers heat and mass with wet solid waste in the channelA special crushing device (special structure design)is equipped to make the moisture in solid waste evaporate quickly.Smaller solid waste particles are discharged from the dryer with the gas and collected while larger solid waste particles stay in the dryer for a long time until drying is completed. Part of the waste gas is extracted treated by deodorizer and discharged into the atmosphere (or cooled by water foam dust removal).
特点
(1)根据固废干化过程中的特性及状态，分段采用不同的分散破
碎装置，大大提高干化效能。
(2)采用特殊密封材料，保证密封效果，且寿命大大提高。
(3)轴承采用冷却装置，降低轴承使用温度，延长使用寿命;
(4)可采用间接加热方式，减少排风量及提高热利用率:
(5)根据不同状态的固废采用不同抄板形式，降低粘结程度:
(6)根据固废特性采用不同的进料方式，以防止进料堵塞。
(1) According to the characteristics and state of solid waste drying process,different dispersing and crushing devices are adopted in stages.
which greatly improves the drying efficiency.
(2) Special sealing materials are adopted to ensure the sealing effect and greatly improve the service life
(3) the bearing adopts a cooling device, which reduces the service temperature of the bearing and prolongs the service life
(4)indirect heating can be used to reduce the exhaust air volume and improve the heat utiization rate
(5) According to the different state of solid waste,different forms of paper making are adopted to reduce the bonding degree:
(6) According to the characteristics of solid wastedifferent feeding methods are adopted to prevent feeding blockage.
