Zusammenfassung:	The utility model relates to an acid gas exhaust preprocessing device of LNG (Liquefied Natural Gas) production equipment. The acid gas exhaust preprocessing device comprises a stripping tower, wherein the lower end of the stripping tower is provided with a return tank; the side wall at the upper end of the return tank is provided with a gas exhaust outlet; the gas exhaust outlet is connected with a pressure regulating valve for regulating the pressure of the stripping tower through a pipeline; the downstream end of the pressure regulating valve is sequentially provided with a gas-liquid separation tank and a desulfurizing tower; an inlet of the gas-liquid separation tank is connected with the pressure regulating valve through a pipeline; an outlet at the top of the gas-liquid separation tank is connected with an inlet of the desulfurizing tower through a pipeline; and an outlet of the desulfurizing tower is connected with a high-altitude exhaust pipe. The acid gas exhaust preprocessing device can be used for
