[0002] The aluminum smelting furnace is a new type of high-efficiency and energy-saving aluminum smelting furnace developed based on the aluminum smelting process. The flue gas emitted from the smelting furnace needs to be collected and cooled before it can be sent to the filtration device for filtration, otherwise the filtration device may be easily damaged by the heat.

[0003] The existing cooling devices for aluminum rod smelting furnaces use spray cooling. However, during the spray cooling process, the high-temperature flue gas flows too fast in the pipes, which prevents the flue gas from coming into good contact with the cooling water, making it difficult to guarantee the cooling effect. Utility Model Content

[0004] The technical problem this invention aims to solve is that during the spray cooling process of flue gas emitted from a smelting furnace, the high-temperature flue gas flows too fast in the pipe, resulting in poor contact between the flue gas and the cooling water, making it difficult to guarantee the cooling effect.

[0008] Furthermore, the cooling assembly also includes a water pump, a distribution pipe, and a nozzle, wherein:

[0009] The water pump is fixedly installed on the cooling pipe, the diversion pipe is fixedly connected to the output end of the water pump, and the nozzles are fixedly connected to the diversion pipe, and they are arranged in a linear pattern.

[0011] Furthermore, the air outlet assembly includes an air outlet pipe, a limiting ring, and a filter plate, wherein:

[0012] The exhaust pipe is threaded to the end of the cooling pipe, the limiting ring is fixedly connected to the outer wall of the exhaust pipe, the filter plate is fixedly connected between the inner walls of the exhaust pipe, and a one-way valve is provided on the exhaust pipe.
