The invention discloses an off-gas handling system with a primary washing tower, a secondary turbulent flushing tower and a tertiary turbulent flushing tower, wherein, the primary washing tower, the secondary turbulent flushing tower and the tertiary turbulent flushing tower are respectively equipped with a first, a second and a third heat exchangers, and the system also has an alkali liquor main pipe, a water inlet, a cooling upper water main pipe, a cooling backwater main pipe and a discharge main pipe; the primary washing tower, the secondary turbulent flushing tower and the tertiary turbulent flushing tower is respectively provided with a liquid membrane foam area, and harmful waste gas passes through the liquid membrane foam areas of the primary washing tower, the secondary turbulent flushing tower and the tertiary turbulent flushing tower in order to be purified. As the waste gas passes through the three strongly turbulent liquid membrane foam areas, the invention achieves the effect of high efficient washing. As the gas-fluid exchange is not carried out in the towers, the structures of the towers are simple, the manufacturing and the maintenance are convenient, and the height of the towers can be greatly reduced. The consumption of the raw material can be greatly reduced, and the investment can be reduced. The circulation solution sprayed out by a spraying head is spiral shaped and is fully contacted with the harmful waste gas for absorption, and the spray nozzle is unlikely to be blocked because of the large size.
