[0023] Specific application examples of the utility model:

[0024] The first condensation plate 11 is arranged on the inner wall of the condensation tank 1. The first condensation plate 11 is arranged in a spiral shape, so that the exhaust gas enters the condensation tank 1 and rotates and rises along the first condensation plate 11 and the inner wall of the condensation tank 1, reducing the gas flow rate. It is conducive to the gas and the condensation plate to fully contact. The first cavity 12 opened in the first condensation plate 11 flows in the coolant, and the coolant is used to condense the exhaust gas. A second cavity 13 is arranged in the side wall of the condensation tank 1, and the same coolant flows, so that the inner wall of the condensation tank 1 can also condense the exhaust gas, further increasing the reaction contact area. The first condensation plate 11 is inclined toward the bottom of the condensation tank 1. It is conducive to the condensed water after the reaction to flow along the upper side of the first condensation plate 11 and drip into the condensate collection tank 2. The first cavity 12 and the upper part of the second cavity 13 are connected to each other, so that the second cavity 13 is arranged in the side wall of the condensation tank 1 in a spiral shape, which is conducive to unifying the coolant temperature in the first cavity 12 and the second cavity 13.

[0025] An annular inner plate 3 is coaxially arranged in the condenser tank 1, and a second condensation plate 31 is arranged on the side of the inner plate 3 close to the side wall of the condenser tank 1.

The second condensation plate 31 is arranged to prevent the condensation water from accumulating between the angle between the first condensation plate 11 and the inner wall when the inner plate 3 is directly connected to the first condensation plate 11. The condensate collection tank 2 is arranged at the bottom of the condenser tank 1 in an annular shape to match the side wall of the condenser tank 1 and the inner plate 3.
