The invention relates to equipment and a process for condensing and collecting steam and waste gas at the tail end of a multi-grade flash evaporation device and belongs to the technical field of production of viscose. The equipment comprises the multi-grade flash evaporation device, wherein the tail end of the multi-grade flash evaporation device is connected with a primary indirect condenser and a secondary condenser; the primary indirect condenser and the secondary condenser are connected through a pipeline; the secondary condenser is connected with a steam injection pump and a tertiary condenser through a pipeline in sequence; the steam injection pump is connected with a steam source; and the tertiary condenser is connected with a vacuum pump and a waste gas treatment system through a pipeline in sequence. The process can be used for completely collecting uncondensed waste gas generated by multi-grade flash evaporation so that all toxic waste gas generated by the multi-grade flash evaporation enters the waste gas treatment system, and furthermore, the air pollution is avoided and the environment is protected.
