A kind of carbon five tail gas recycling and treating device, comprises first-stage condenser (2), secondary condenser (3), carbon five groove (4), tail gas buffer (5), two liquid ring vacuum compressors (6), cooler (7), gas-liquid separator (8), three grades of condensers (9), carbon five recycling can (10), the first carbon five pump (11), the second carbon five pump (13) and catalytic oxidizing equipments (12).From process units holding vessel, reactor emptying end gas through collecting pipe collect after, enter one-level, secondary condenser, major part is condensed into liquid and enters liquid storage vessel, failing the tail gas of condensation enters surge tank, and through liquid ring vacuum compressor compresses, in gas-liquid separator, gas-liquid two-phase is separated, liquid enters carbon five recycling can, gas enters condenser and is condensed into liquid again and enters carbon five recycling can, and incoagulable gas and low concentration carbon five enter catalytic oxidizing equipment, realize qualified discharge. |
