The invention relates to a taper core type supersonic condensation cyclone separator, belonging to the technical field of expansion refrigeration and condensation separation of pressure gas. The taper core is inserted in a passage, and the diameter of the taper core is changed at different places, so as to form the passage with a gradually decreased section part, a constant throat part and a gradually increased section part; therefore, a constant diameter inner hole can be adopted to avoid gradually increased small taper pipe passage which is difficult to be machined, so that the spin strength is not weakened due to the diameter increase. The taper core type supersonic condensation cyclone separator enables low-temperature working condition by means of pressure expansion and cooling of the gas, and reinforces spin by means of diameter decrease to generate strong centrifugal force field.
