1．1干燥设备目前有多种技术应用，其中热风干燥是最常用的设备之一，但由于工作能耗大，应用范围在逐步缩小；另有除湿干燥和真空负压干燥设备，两者各有优势，下面对除湿干燥做单独介绍，建议用户使用。

1．2除湿干燥机工作原理

1．2．1露点保持在-40℃，去除水份，使吹入料斗中的热空气几乎是不含水分的。
1．2．2经循环使用时含有水分的湿热空气在气流的出口处，重新送至水分去除之前的部位分子筛进风口处，已使用的热空气完全进入下一环节，所有的热量没有一点损失，都重新利用起来，故节能、环保。
1．2．3所有工艺参数均是通过触摸接触直接输入，直观明了。
1．2．4各种参数工作状态直接反映在显示屏上，并自带保存功能，可以将工作状况完整的保留下来。
1．2．5机器所含有的各项报警功能，能自动检测到机器的工作运行是否正常，使机器使用时的故障率处在最低水平。


1．3除湿干燥机主要部件
1．3．1触摸屏
对机器的运行状态进行控制，使机组的工作是按所设定的要求进行的；将机组的各种工作如实的反馈给控制中，便于核心控制器将设置命令与实际工艺参数进行对比，及时修正偏差；通过各触点的快速通/断区分，机组的实际运行参数更接近设定参数。
1．3．2旋风分离装置
料粒之间空隙移动，气流中含有的一部分微细粉尘颗粒被此分离装置拦截下来，所经过的空气流是较为洁静的。通过压差观察装置，直接知晓气流循环通道中流量，在需要时能快速清理过滤装置，使空气流中的粉尘易于粘附在上面，以便于更好的清理。及时分离了气流中的粉尘颗粒，保持了干燥机的气体通流量，保持了干燥效率。
1．3．3再生风量补充
对补充气流部分的气体进行过滤，使此部分气体是符合除湿分子筛的要求。通常情况下过滤网采用发孔式石棉布，清理方便。
1．3．4分子筛
已含有水分的分子筛孔，在经过缓慢转动（自转）的筛网时，有1/3区域设置了再生温度，这一区域的温度能迅速地让水分气化蒸发，故经过再生干燥后的分子筛依旧是完全干燥的。如此不断的循环。保持分子筛孔内通畅，即保持了良好的干燥效率。






大气环境下含有一定湿度的气体，经过露点处于-40℃在左右的分子筛孔过滤，使水分子残留在分子筛孔内，通过的气流是几乎不含水分的，如此保持最佳的干燥效果。
1．3．5过滤装置
在封闭式气流循环中，安装在控制柜中的过滤装置，对通过的气流进行过滤，净化进入分子筛前的空气，起到保护分子筛通透性，延长其寿命的作用。
1．3．6冷却装置
将循环气流中流出干燥筒气体，送入该冷却器，使这些气体的实际温度低于60℃，再将已冷却过的气体送入除湿分子筛。延长其寿命之作用。










1.1 There are a variety of drying equipment, technology applications, including hot air drying is one of the most commonly used equipment, but the work of energy consumption and gradually narrow the scope of application; another desiccant drying and vacuum drying equipment, both their respective advantages, the following description of the desiccant to do alone, the proposed use.






1.2 Dehumidifier Works


 


 


1.2.1 keep the dew point -40 ℃, removal of water, so that the hot air blown into the hopper is almost without water.


1.2.2 The cycle of water use with hot and humid air in the air at the exit and re-sent to the site prior to removal of zeolite water inlet, used hot air full access to the next link, there is no point to all of the heat losses are re-used up, so energy saving and environmental protection.


1.2.3 All process parameters are entered directly through the touch contacts, simple and clear.


1.2.4 Working status of various parameters directly reflected in the display, and built-save feature, working conditions can be preserved complete.


1.2.5 machines with the alarm function, can automatically detect whether the normal operation of the machine, the machine failure rate when used at the lowest level.






1.3 The main components Dehumidifier


1.3.1 Touch Screen


Running on the machine control, so that unit's work is carried out in accordance with the requirements set by the; to the various work units to control accurately the feedback, easy to set up command central controller compared with the actual process parameters, time error correction; through the contact of fast on / off distinction unit closer to the actual operating parameters to set parameters.


1.3.2 cyclone separation device


Granules of the gap between the moving part of air containing fine dust particles are the separation device block down, the passing air flow is relatively Jie Jing's. Observed by differential pressure devices, direct knowledge of air circulation in the flow channel, the need to quickly clean-up filter, the air flow in the dust easily adhere to the above, in order to facilitate better cleaning. Time separation of the gas in the dust particles, keeping the dryer's gas through the flow maintained a drying efficiency.


1.3.3 Renewable wind added


Some of the additional gas flow filter, so that this part of the gas is consistent with the requirements of molecular sieve desiccant. Typically filter cloth with hair-hole stone, clean up easily.


1.3.4 Zeolites


The molecular sieve has holes with water in a slow rotation (rotation) of the screen, there are 1 / 3 of the regional set up regeneration temperature, the temperature of the region make water gasification can quickly evaporate, so after regeneration of molecular sieve after drying is still completely dry. This constant cycle. Maintain the smooth hole sieve, which maintained a good drying efficiency.


 


 


 


Atmospheric environment with a certain humidity of gas, after the dew point is -40 ℃ in about zeolite pore filter, the water molecules left in the sieve hole, through the air is almost no water, so to maintain the best drying results.


1.3.5 Filtration


In a closed air loop, installed in the control cabinet in the filter, the airflow through the filter, purify the air before the molecular sieve, molecular sieve permeability protect and prolong its life role.


1.3.6 Cooling Device


Air in the drying out of the loop tube gas, into the cooler, so the actual temperature of these gases below 60 ℃, then the gas has been cooling off into the molecular sieve desiccant. Extend the life of the role.
