Controllable organic waste gas circulation desorption system of concentration

The utility model discloses a controllable organic waste gas circulation desorption system of concentration, including temperature control box, adsorption tower, buffer tank, backflow fan and back processing apparatus, temperature control box, adsorption tower, buffer tank and back processing apparatus connect gradually through the pipeline, the temperature control box with still be equipped withbackflow pipeline between the buffer tank, backflow fan sets up backflow pipeline is last. This system has not only improved organic waste gas concentration in the desorption air current, has reducedthe energy loss of subsequent processing device, and reduced desorption air current flow, make subsequent processing equipment volume diminish. And because a lot of desorption can suitably reduce thedesorption temperature, the system security performance obtains improving. 本实用新型公开了种浓度可控的有机废气循环脱附系统，包括温控箱、吸附塔、缓冲罐、回流风机和后处理装置，所述温控箱、吸附塔、缓冲罐和后处理装置通过管道依次连接，所述温控箱和所述缓冲罐之间还设有回流管道，所述回流风机设置在所述回流管道上。该系统不仅提高了脱附气流中有机废气浓度，减少了后续处理装置的能量损耗；而
