The invention discloses a heat-pipe-type gradual injection type device for directly generating steam and a method. A heat-pipe-type vacuum heat collecting pipe is adopted to replace the existing metal-glass straight-through vacuum heat collecting pipe to form a heat-pipe-type gradual injection DSG system. The invention not only can retain the advantages of a single loop of a common DSG system relative to routine spotlight solar energy heat utilization double loops, but also can separate a pressure-bearing part and a heat absorption part of the DSG system, utilizes a heat pipe technology to realize the separation of source and sink, and leads a plurality of condensers (1) to be arranged in series or parallel connection, leads the collective sunlight to transmit a glass outer pipe (2-1) anda vacuum chamber (2-2) of the heat-pipe-type vacuum heat collecting pipe (2), and heats the working medium (2-5) in the evaporation section of a heat pipe (2-4) after the collective sunlight is absorbed by a selective absorption coating (2-3); the working medium (2-5) in the evaporation section of the heat pipe (2-4) is evaporated and rises up to a condenser section of the heat pipe (2-4); and theworking medium (2-5) condenses into liquid to turn back to the evaporation section of the heat pipe (2-4) for cycle use after the steam in the working medium (2-5) transmits the heat to the cooling medium water (3) in a system main pipe (5).
