The invention discloses condensation separation equipment for sulfur recycled tail gas. The equipment is formed by sequentially connecting an upper barrel, a cooling section barrel and a lower barrel from top to bottom. The upper barrel serves as a tail gas feed section, a tail gas inlet is formed in the top, and a gas distributor is arranged at an inlet of the tail gas inlet; the cooling section barrel serves as a tail gas cooling section and comprises an upper tube plate, a lower tube plate, a heat exchange tube bundle and a baffle plate set, wherein the upper tube plate and the lower tube plate are arranged at the two ends, and the heat exchange tube bundle and the baffle plate set are arranged between the two tube plates. The heat exchange tube bundle is composed of multiple parallel heat exchange tubes, the baffle plate set is composed of multiple baffle plates installed on the two sides of the inner walls of the barrels in a vertically staggered mode, tube holes are formed in the baffle plates, and the heat exchange tube bundle penetrates through the tube holes to be vertically fixed between the two tube plates; the lower barrel serves as a liquid sulfur separation section, a tail gas outlet is formed in the side wall of the upper portion of the lower barrel, a liquid sulfur outlet is formed in the bottom, and the outer portion of the lower section is sleeved with an outer jacket. The problem that sulfur steam is carried by outlet tail gas of a sulfur recycling device is solved, tail gas SO2 emissions are reduced, and the sulfur recycling rate of the device is increased.
