Acetic acid tank tail gas condensate recovery device

The invention discloses an acetic acid tank tail gas condensate recovery device which comprises a tail gas pipe communicated with an acetic acid tank and a washing tower, the tail gas pipe is provided with a low-position pipe, the low-position pipe of the tail gas pipe is downwards communicated with a liquid collecting pipe, the bottom of the liquid collecting pipe is communicated with a liquid collecting tank, and a timing valve is arranged on the liquid collecting pipe. The timing valve can be started regularly so that the liquid collecting pipe can drain liquid regularly. According to the invention, the liquid collecting tank and the heat tracing are additionally arranged at the inverted spraying position of the low-position pipe of the tail gas pipe, and acid-containing condensate of the low-position pipe is regularly discharged to the liquid collecting tank of the acetic acid device for recovery, so that the smoothness of the tail gas pipeline is ensured, and the acetic acid condensate is recovered.
