Description

一种新型的模块化冷干机 技术领域
本发明涉及一种新型的模块化冷干机。
背景技术
冷干机主要由热交换系统、制冷系统和电气控制系统三部分组成。从空压机出来的热而潮湿并含有水分的压缩空气首先经过空气对空气热交换器预冷却；然后经过预冷却的空气，在空气对冷媒热交换器被冷干机的冷冻剂循环回路进一步冷却，与已经从蒸发器出来被冷却到压力露点的冷空气进行热交换，使压缩空气的温度进一步降低。之后压缩空气进入蒸发器，与制冷剂进行热交换，压缩空气的温度降至0℃-8℃，空气中的水分在此温度下析出，通过冷凝器将压缩空气中冷凝出的水分油和杂质分离，通过排水器将其排出机外。而干燥的低温空气则进入空气对空气交换器进行热交换，温度升高后输出。传统的冷干机一般选用单机预冷器、蒸发器和气水分离器通过管路进行连接，如此，设备的间的管路连接方式较为复杂，使得设备成本以及设备的外形尺寸都相对较大。
 技术解决方案
为了解决上述的技术问题，本发明的目的是提供一种新型的模块化冷干机，该冷干机能大大减少繁重的管路连接工作、使得生产成本更低，还能大大节省安装空间。
为了达到上述的目的，本发明采用了以下的技术方案：
一种新型的模块化冷干机 ，该冷干机是由一块端板、若干预冷器换热板片、若干蒸发器换热板片、一个气水分离器和一块带清洗孔的底板依次堆叠、钎焊而成；所述端板上设有湿热空气进口接管和干燥空气出口接管，所述气水分离器由多块带孔的板片堆叠、焊接构成，所述底板上设有制冷剂进口接管制冷剂出口接管和排水接管，并在清洗孔外侧安装有密封板。
作为优选方案：所述气水分离器是由多块带孔的板片堆叠、焊接而成，板片上的孔堆叠后形成一个空腔，并且在空腔内放置丝网、折流板或者旋风分离装置。
作为优选方案：所述气水分离器集成在端板位置，气水分离器底部设置储水器空腔。
有益效果
本发明由于采用以上技术方案，利用板式热交换器作为预冷器和蒸发器。换热板片之间以焊接密封，形成传热板两侧的冷/热流体通道，在流动过程中通过板壁进行热交换。两种流体在流道内呈逆流式换热态势，这种方式可提高预冷回热器换热效率，缩小了进出口的温差，使得压缩空气以更低的温度进入蒸发器。本发明还简化了设备间的管路连接方式，使得设备成本以及设备的外形尺寸都大大缩小。
附图说明
图1是该模块化冷干机的结构示意图。
本发明的实施方式
下面结合附图对本发明的具体实施方式做一个详细的说明。
如图1所示的一种新型的模块化冷干机，该冷干机是由一块端板100、若干预冷器换热板片200、若干蒸发器换热板片300、一个气水分离器400和一块带清洗孔604的底板600依次堆叠、钎焊而成；所述端板100上设有湿热空气进口接管101和干燥空气出口接管102，所述气水分离器400由多块带孔407的板片405堆叠、焊接构成，所述底板600上设有制冷剂进口接管601、制冷剂出口接管602和排水接管603，并在清洗孔604外侧安装有密封板700。
所述气水分离器400是由多块带孔407的板片405堆叠、焊接而成，板片405上的孔407呈矩形，其开设在板片405中心位置，板片405上的孔407堆叠后形成一个空腔406，并且在空腔内放置丝网500；所述气水分离器400集成在端板100位置。
该新型的模块化冷干机的工作路径是如下实现的：湿热空气从端板100的湿热空气进口接管101，预冷器换热板片200的第一角孔201进入由相邻预冷器换热板片200组成的第一预冷器换热通道；由经过蒸发器的低温干燥空气进行预冷却，预冷后的空气经预冷器换热板片200的第二角孔202和蒸发器换热板片300的第三角孔302流入由相邻蒸发器换热板片300组成的蒸发器换热通道；在此区域被制冷剂进一步冷却到露点温度，同时析出水分；气水混合物经蒸发器换热板片300的第四角孔301进入板片405的第五角孔401流入由相邻板片405和丝网500组成的内置气水分离器400；被气水分离器400分离出的水经板片405的第五角孔401和排水接管603排出，同时，析出水分的低温干燥气体经板片405的第六角孔402和蒸发器换热板片300的第七角孔300流入预冷器换热板片200的第八角孔203，最后流入由相邻预冷器换热板片200组成的第二预冷器换热通道，在此区域析出水分的低温干燥气体与刚进入冷干机的湿热空气进行热交换，被加热后经由预冷器换热板片200的第九角孔204 和干燥空气出口接管102流出。制冷剂从底板600的制冷剂进口接管601，穿过板片405的第十角孔403和蒸发器换热板片300的第十一角孔303，进入由相邻蒸发器换热板片300组成的第二蒸发器换热通道，在此区域将预冷过的湿热空气冷却到露点温度，蒸发后的制冷剂通过蒸发器换热板片300的第十二角孔304和板片405的第十三角孔404经底板600的制冷剂出口接管602流出。当需要对气水分离器400中的丝网500进行清洁或更换时，可将安装于底板600的清洗孔604上的密封板700可进行拆装。
最后，应当指出，以上实施例仅是本发明较有代表性的例子。显然，本发明包含不仅限于上述实施例，还可以有许多变形。例如，气水分离器400可内置丝网500、折流板、旋风分离或其他形式装置。由板片405构成的内置气水分离器400也可由其他形式替代，如金属壳体等。气水分离器400的集成方式可以是上述的一体焊接也可以是可拆安装。为方便清洁或更换丝网500等装置，在冷干机的底板600上所设置的清洗孔604也可视使用需求而取消。集成于冷干机的底板600上的气水分离器400，也能够放置于端板100位置。气水分离器400的排水可以通过排水接管603向外排水，也可以由气水分离器400底部直接向外排水。气水分离器400也可根据需要设置储水器空腔。
