Apparatus and process for treating synthetic leather exhaust gas

The invention discloses an apparatus for treating synthetic leather exhaust gas. The apparatus comprises a DMF absorbing tower, a demister, a photoelectric integrated device, a spiral flow plate absorbing tower and an exhausting pipe which are successively communicated, wherein the DMF absorbing tower is provided with an air inlet allowing introduction of synthetic leather exhaust gas, an outlet of the DMF absorbing tower is communicated with an inlet of the demister through a first air duct, an outlet of the spiral flow plate absorbing tower is communicated with an inlet of the exhausting pipe through a second air duct, the photoelectric integrated device comprises a shell and a filtering section, a photocatalysis section, a discharge treating section and an active carbon absorption section which are successively arranged in the shell, one side of the filtering section is in butt joint with an outlet of the demister, and one side of the active carbon absorption section is in butt joint with an inlet of the spiral flow plate absorbing tower. The apparatus provided by the invention separately employs the DMF absorbing tower, the photoelectric integrated device and the like to remove harmful components in exhaust gas with different processes in sections according to different physicochemical properties of each component, can realizes regeneration and recovery of DMF and has the advantages of low energy consumption, high removal efficiency and no secondary pollution.
