Sulfur-containing gas field tail gas treatment device

The utility model relates to the technical field of gas field tail gas treatment, in particular to a sulfur-containing gas field tail gas treatment device. The treatment device comprises an alkali liquor reaction tank, the top of the alkali liquor reaction tank is provided with an alkali liquor filling port, the alkali liquor filling port is connected with a filling channel, the alkali liquor filling port is provided with a check valve, and the check valve is used for preventing gas in the alkali liquor reaction tank from reversely flowing into the filling channel. The check valve prevents tail gas from flowing out of the alkali liquor filling port when air pressure in the alkali liquor reaction tank rises suddenly, the filling channel prolongs the filling length of alkali liquor, and when gas enters the filling channel, part of overflowing tail gas can be prevented from agitating the alkali liquor to overflow and splash, so that damage to the reaction tank and workers is avoided. 本实用新型涉及气田尾气处理技术领域，特别涉及一种含硫气田
