The sulfur-containing tail gas is a common tail gas in the chemical industry field and mainly comprises harmful gases such as sulfur dioxide, hydrogen sulfide, ammonia and the like. If the tail gas is directly discharged into the atmosphere, the tail gas can cause atmospheric pollution. After the sulfur-containing tail gas is treated by a reaction furnace and a sulfur condenser, part of gasified sulfur and other sulfides still exist, and a catcher is generally arranged behind the sulfur condenser for catching sulfur steam in the process gas by the sulfur recovery device so as to gather the sulfur steam into small liquid drops for recovery. The equipment can improve the sulfur recovery rate, reduce the sulfur steam from entering the incinerator and reduce the exhaust emission. At present, a plurality of traps are used in a silk screen structure, and the trapping effect of the traps is poor in actual operation, so that all gaseous sulfur cannot be collected. The gaseous sulfur is partially liquefied due to the temperature decrease during the subsequent pipeline transportation.

In order to solve the problem, the penholder redesigns a process gas pipeline, sets a liquid collecting tank on the process gas pipeline, and drains accumulated sulfur to a sulfur sealing tank by gravity of liquid sulfur to ensure stable operation.
