The interior of the lime water tank stores lime water for filtering air, the exhaust pipe is used to discharge the filtered air to the outside, and the control valve is used to control the opening and closing of the exhaust pipe.

[0018] Beneficial effects:

[0019] 1. The exhaust gas from the can-making and drying oven is pumped into the can-making and drying oven exhaust gas incinerator through an air pump and an air inlet pipe. The can-making and drying oven exhaust gas incinerator 1 incinerates the exhaust gas.

[0020] 2. The exhaust gas from the can-making and drying oven is incinerated and then fed into a lime water tank via a conveying pipe. The liquid inside the lime water tank adsorbs dust from the air.
