Description

生物质原料烘干机
技术领域
    本实用新型涉及烘干机领域，具体属于生物质原料烘干机。
背景技术
生物质燃料的制备需要多种机械设备，主要有粉碎机、烘干机，搅拌混合机，挤压成型机，包装机等。既有成套流水线，也有单台组合使用。原料可以是木屑、锯末、竹末、树叶、玉米秸、花生皮、葵花子皮等谷壳。现有的烘干机结构设计不合理，不能满足要求。
实用新型内容
本实用新型的目的是提供一种生物质原料烘干机，利用裂解设备加热过程中产生的余热尾气为热源，不增加其他热能，物料靠势能运动，无需其他动力，余热利用率达到80-90%。
本实用新型的技术方案如下：
生物质原料烘干机，包括有烘干筒，烘干筒上端、下端分别设有进料机，进料机上设有伸入到烘干筒上端的加料管，加料管内壁上设有交错排布的分料板，烘干筒内设有多个扩散器、集料器，烘干筒上端、下端侧壁上开有尾气进口、尾气出口。
所述的扩散器与集料器组合成一体。
本实用新型物料由输送机送至烘干机顶部，进入烘干机。由分料板将物料打开、分散，蓬松的物料经扩料器扩散，沿周边下滑至集料器，该过程物料由集中至分散，又由分散至集中，完成了一次与尾气地热交换过程。如此过程在烘干机内将反复5次。最终由出料机输出，余热尾气由进口自下而上通过烘干机由出口进入烟道排放。整个过程遵循热交换原理，提高导热率。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图，生物质原料烘干机，包括有烘干筒1，烘干筒1上端、下端分别设有进料机2，进料机2上设有伸入到烘干筒1上端的加料管3，加料管3内壁上设有交错排布的分料板4，烘干筒1内设有多个扩散器5、集料器6，扩散器5与集料器6组合成一体，烘干筒1上端、下端侧壁上开有尾气进口7、尾气出口8。
该设备是利用裂解设备加热过程中产生的余热尾气为热源。不增加其他热能。物料靠势能运动，无需其他动力。余热利用率达到80-90%。尾气与需要烘干的生物质原料直接接触，并利用设备内部结构最大程度地増加物料与尾气的接触面积，使物料迅速增加温度。从而使物料内部的水分蒸发，物料温度上升。
当入烘干机原料含水率在12%左右，余热尾气温度达到500℃时。经过约3-5秒，物料在烘干机内部利用自身重力自上而下的走完行程。此时物料温度将达到130-140℃、含水率下降至3-4%。余热尾气温度下降至50℃。
