The discharged nitrogen-sealed tail gas is collected into a nitrogen-sealed tail gas main pipe, and is pressurized by a tail gas draught fan and then is sent to a gas suction pipeline. If the condition of the suction gas pipeline is not sent, the gas can also be sent to the incineration system. Before the nitrogen-sealed tail gas is sent into a gas suction pipeline or an incineration system, the oxygen content in the nitrogen-sealed tail gas needs to be monitored, and under some extreme conditions, a large amount of air can be supplemented through a breather valve due to the fact that nitrogen is not supplemented timely.
