The invention discloses an energy-saving and environment-friendly purification and exhaust incinerator for surrounding and freezing sulfur-containing waste gas. The energy-saving and environment-friendly purification and exhaust incinerator structurally comprises an exhaust column barrel, a shell sleeve body, a water condensation gas chamber, a combustion machine, a double-layer stirring kettle, an incineration chamber and a water tank, wherein the bottom end of the water condensation gas chamber communicates with the top end of the incineration chamber, the combustion machine is inserted intothe upper left corner of the incineration chamber and communicates with each other, the double-layer stirring kettle is arranged in the incineration chamber, the water tank is arranged on the right side between the water condensation gas chamber and the incineration chamber, and the exhaust column barrel is inserted into the right upper corner of the water condensation gas chamber and communicates with each other. According to the energy-saving and environment-friendly purification and exhaust incinerator, the matching of the water condensation chamber and the water tank through the water condensation gas chamber is achieved, the transpiration gas is collected and purified through the bottom end of a balloon breathable tube of an ellipsoidal bag, the effect that soluble gas is taken awayby water-cooled tube water flow is formed by butt joint of an air-permeable hose, the superposition cooling effect of a coolant manufactured by desulfurization is formed, the shell of the incineratoris promoted to be protected and cooled, and the effect that the characteristics of sulfur are fully utilized to surround the freezing protection from the inside to the outside is achieved.
