Description

一种贯通式烘干设备 技术领域
本发明涉及洗衣技术领域，特别涉及一种烘干设备，尤其是一种贯通式烘干设备。
背景技术
烘干机可分为工业与民用两种，工业烘干机也叫干燥设备或干燥机，民用烘干机是洗涤机械中的一种，一般在水洗脱水之后，用来除去服装和其他纺织品中的水分。烘干机有带式烘干，滚筒烘干，箱式烘干，塔式烘干等几种模式；热源有煤，电，气等；物料在烘干过程中有热风气流式和辐射式等，热风滚筒烘干是热气流从尾部向前运动，与物料充分接触，通过热传导、对流、辐射传热量充分利用；将热能直接传递给物料，使物料的水分在筒体内不断被蒸发，入料口的引风装置将大量的水分、湿气流抽出，防止粉尘外排造成的二次污染；通过内螺旋搅拌、扫散、抄板，推进物料运动，完成整个烘干过程；逆流传导脱湿，避免减少重复烘干程序。贯通式烘干机是洗涤行业常见的烘干设备。
贯通式烘干机是洗涤机械中的一种，一般在水洗脱水之后，用来除去服装和其他纺织品中的水分。大多数的烘干机包括一个旋转的滚筒，内筒通过皮带驱动，在滚筒的周围有热空气用来蒸发水分。烘干筒都是采用滚筒正反转的原理，来达到烘干物品的不缠绕效。通过电力、柴油力、风力、易燃物力等产生动力利用环境空气加热，输送到贯通周围，进而达到适当温度进行除湿处理。湿物料由皮带输送机或斗式提升机送到料斗。加料管道的斜度要大于物料的自然倾角，以便物料顺利流入干燥器内。干燥器圆筒是一个与水平线略成倾斜的旋转圆筒。物料从较高一端加入，载热体由低端进入，与物料成逆流接触，也有载热体和物料一起并流进入筒体的。随着圆筒的转动物料受重力作用运行到较底的一端，湿物料在筒体内向前移动过程中，直接或间接得到了载热体的给热，使湿物料得以干燥。
但本申请发明人发现上述技术至少存在如下技术问题：
现在的贯通式烘干机消耗蒸汽大，为了效率不惜用大量蒸汽来就行烘干，增大了蒸汽使用量，而且内循环系统不完善，导致很多能源被浪费。贯通式烘干机把常温中的风吸入机器内，再通过蒸汽加热，从25℃升温到110-150℃，此时对25℃的风进行升温是需要很多的蒸汽的，需要大量的能源耗用，增加了生产成本，并且排出的废气是高温的，这部分热能是对环境造成破坏。烘干机排出的冷凝水中，包含了闪蒸汽，闪蒸汽也会对环境造成伤害，增加城市的热污染问题。国外进口的设备中，更多的技术点在于减少人力而非节约能耗，然而能源成本在国内占生产成本高于在国外所占的生产成本。
发明内容
本发明要解决的技术问题是提供一种贯通式烘干设备，解决了现有技术中的烘干设备能耗过大且对环境造成损害以及生产成本高的问题，达到了节约能源和保护环境以及降低成本的技术效果。
为了解决上述技术问题，本发明的技术方案为：

具体实施方式
下面结合附图对本发明的具体实施方式作进一步说明。在此需要说明的是，对于这些实施方式的说明用于帮助理解本发明，但并不构成对本发明的限定。此外，下面所描述的本发明各个实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互组合。本申请实施例的技术方案通过提供一种贯通式烘干设备，解决了现有技术中能耗过大且对环境造成损害以及生产成本高的问题，在结合第一、第二、第三和第四升温装置下实现了节约能源和保护环境以及降低成本有益效果。
本发明为解决上述技术问题的实施方案的总体思路如下：
采用与热泵的连接的第一升温装置、设有与烘干机组相连的热风交换箱的第二升温装置、设有与烘干机组连接的闪蒸汽冷凝水交换箱的第三升温装置以及设有蒸汽热交换箱的第四升温装置等一系列技术手段，使得通过利用蒸汽、烘干机组排出的热废气以及闪蒸汽冷凝水和热泵的使用对需要加热的空气进行四次加热，把原本空气进入烘干机组前需要从25℃升温到110-150℃，要升温100多度的升温幅度变为通过本发明技术方案在空气进入烘干机之前只需要升温20℃-65℃，节约能源40％以上。
使用时：通过贯通式烘干机设备中自身的能源进行一个系统性的自身热交换循环，可以通过四次热交换来对用于烘干机组的空气进行加热。第一次，因为热泵的热效比为1:4，加热的成本远低于蒸汽，所以用热泵把常温中约25℃的风加热成45-55℃的风。第二次，45-55℃的热风在特定的交换箱中与烘干机排出来的50℃-80℃的风进行热交换，把45-55℃的热风升温到55-65℃；随后，烘干机排出来50℃-80℃的风还可以与冷水进行一次热交换，把16-30℃的冷水加热城30-50℃的热水，用于洗涤及其他用途。第三次，55-65℃的热风在热交换箱中与烘干机排出来的120℃-125℃的冷凝水和闪蒸汽进行热交换，升温到65-95℃以 上。第四次，65-95℃的热风在蒸汽热交换箱中再次与130℃-170℃的蒸汽进行热交换，升温至110-150℃。经过四次热交换后，进入烘干机中。
为了更好的理解上述技术方案，下面将结合说明书附图以及具体的实施方式对上述技术方案进行详细的说明。
