The chain links fall into the cooling liquid in the cooling box 1 through the guide plate 3, and the flue gas moves upward and is sucked into the suction pipe 4, and then is treated through the air intake manifold 10, the exhaust fan 5 and the flue gas treatment system 6. Since the feed inlet and the discharge end of the guide plate 3 are arranged in a staggered manner, the flue gas can be effectively prevented from escaping through the feed inlet, thereby avoiding the flue gas from being dispersed to the outside and being inhaled by the workers, and thereby ensuring the health of the workers. After the chain links in the chain quenching converter 2 are all dropped and quenched, the suction pipe 4 and the air intake manifold 10 are disconnected, the cover plate 7 is folded, and the chain links are taken out of the cooling box 1.
