The utility model relates to the technical field of rectification waste heat recovery, in particular to a rectification tower top waste heat recovery system. Comprising a heat exchanger, a steam pocket, a pressure control device, a pressurizing unit and a reboiler. According to the rectifying tower top waste heat recovery system provided by the utility model, the heat exchanger, the steam pocket, the pressure control device, the pressurizing unit and the reboiler are adopted, so that a high-temperature gas phase rectified from the top of the rectifying tower can be fed into the heat exchanger for heat exchange, condensate in the heat exchanger is heated and vaporized to generate steam, and the steam is fed into the steam pocket; the pressure of the steam pocket is controlled to be constant through the pressure control device, the steam discharged from the steam pocket is pressurized by the pressurizing unit, so that the temperature is increased, the steam is fed into the reboiler for heat exchange, the steam
