The utility model relates to a high-pressure compressor dry gas seal. A shaft sleeve is sleeved on a rotary shaft, one end surface of the shaft sleeve is a U-shaped groove, a movable ring A is embedded in the U-shaped groove of the shaft sleeve, an annular movable ring base sleeve is sleeved on the shaft sleeve, one end of the annular movable ring base sleeve contacts with the end surface of the movable ring A while the other end forms an L-shaped structure, a static ring A, a push ring A, a spring A and a spring base A are sequentially disposed in a space formed by the movable ring A and the movable ring base sleeve, a compressing sleeve is sleeved outside the shaft sleeve, the outer wall at one end of the compressing sleeve forms the U-shaped groove with the L-shaped structure of the movable ring base sleeve, a movable ring B is embedded in the U-shaped groove, a static ring B, a push ring B, a spring B and a spring base B are sequentially arranged, comb teeth are sealed at connecting positions of the spring base A, the spring base B and a movable ring base, a carbon ring gland is fixed on a carbon ring base fixed on the spring base B, and a carbon retainer ring, a carbon ring and a carbon ring pull spring are disposed between the carbon ring gland and the carbon ring base. The high-pressure compressor dry gas seal can bear pressure of 17.2 MPa which is larger than pressure of 10.0 MPa born by domestic compressor dry gas seals.
