Activated carbon fiber organic waste gas purifier for in vitro regeneration carbon fiber organic waste gas purifier (organic waste gas treatment device). Using carbon fiber as adsorption material, its adsorption capacity is 20 to 40 times higher than activated carbon, purification efficiency is 95 to 99%, the equipment has a small footprint, easy to maintain, less ancillary equipment, wide range of applications, high, low concentration of odor, waste gas has a better odor removal effect. Low operating cost, simple operation and easy maintenance. No secondary pollution, low energy consumption, small load on the surrounding environment. Is the international operation for many years and has been successful method, is a relatively mature process.
