AI Technical Summary
In existing technologies, the oil mist in the fumes condenses on the heat exchange tubes and adheres due to its viscosity, which increases the wall thickness of the heat exchange tubes, reduces the heat transfer performance, and results in low oil fume separation efficiency, making it difficult to meet environmental emission requirements.
The device employs a spiral exhaust pipe and a lifting mechanism. Under negative pressure, the oil fumes enter the device and undergo heat exchange through the heat exchange tubes. The condensed oil and water adhere to the heat exchange tubes. The lifting mechanism moves the heat exchange tubes up and down, causing them to impact the housing and quickly remove the oil and water, thus avoiding any impact on the heat exchange performance.
It achieves efficient separation of oil mist in cooking fumes, improves the heat transfer performance of heat exchange tubes, and ensures that cooking fumes meet environmental emission standards.
