Apparatus for recovering ethanol in organic exhaust gas from tipping paper printing

The invention discloses an apparatus for recovering ethanol in organic exhaust gas from tipping paper printing. In production technology of printing industry, usage of a great amount of organic solvent causes indoor air pollution. The apparatus of the invention comprises a filter (2), a blower fan (3), a secondary surface cooler (4), an absorber assembly (5), a desorption device condenser (8), a gas-liquid separation device (10), a liquid storage tank (11) and a rectifying tower (12). An 80-mesh primary sieve (17) is arranged on one side of an air intake of the filter (2) casing; a 120-mesh secondary sieve (18) is arranged on one side of an air outlet; and the absorber assembly (5) comprises three horizontal absorbers (6) in parallel connection. If employed, the apparatus for treating printing exhaust gas of the invention not only improves pollution caused by direct discharge but also effectively recovers ethanol in the printing exhaust gas, at low cost and low energy consumption.
