A tail gas recovery device can be mounted at the air outlet to recover the gases that can't condense or be compressed, such as cyclopentadiene, benzene, toluene, toluene, alcohols and other gases difficult to recover due to their low boiling point and easy to cause environmental pollution. The product has such features as energy saving, low noise and low repair rate.
