STRUCTURAL CHARACTERISTICS AND TECHNICAL PERFORMANCE
　　The device adapts high ef fect ceramics wave filler . The body of distillation tower is made of stainless steel. In this way it can prevent from the phenomenon of filler block caused by scrap iron and its life is prolonged. All parts that will contact ethanol in the device such as condensor , buffer tank, cooling snake pipe are made of stainless steel in order to guarantee that the finished product, ethanol, is not polluted.Model W still may use disassembled U type heating pipe. When maintenance, it can be removed out to the still. So it is very convenient to clean the outer wall of heating pipe and the inner wall of still .
　　In Model ZW , the indirect heating still is omitted. The condensor adapts calandria heat exchanger . Of course the screw plate heat exchange and coil pipe cooler can also be provided as request. When adapt coil pipe cooler , the buf fer tank.
APPLICATIONS
　　 The device is suitable for recovering dilute ethanol of pharmaceutical industry ,foodstuff industry, light industry, chemical industry and so on. It is also suitablefor distilling solvents such as methanol and so on. Using this device, about 300 of dilute ethanol can be distilled into 90 ′950 as request. If the nished product has higher requirement to alcohol content, the ratio of reex should be increased. But the output will be decreased.
CONSTITUTES OF DEVICE
　　 Model W hasve specications. Each specication is equipped with distillation tower, still, condusator , buffer-tank, measurer of specic gravity. In which, distillation tower of Model W-200, W-300 is installed on the still directly and distillation tower of Model W-400, W-500, W-600 is installed with still separately .
　　Model ZW has two specications. Each specication is equipped with distillation tower, still, condusator , buffer-tank, measurer of specic gravity.
　　Other auxiliary equipment and meters and instruments such as measure tank, s torage tank, pump, rotameter and temperature indicator should be prepared by customer . Our factory can also provide through additional process or order instead of customer as request.
