AI Technical Summary
Existing technologies cannot accurately control flue gas temperature and provide the optimal catalytic reaction temperature to remove carbon monoxide, and traditional filter elements are insufficient in terms of cooling and filtration effects.
The filter element design employs a combination of cellulose acetate section, catalytic filtration section, and phase change cooling section. The phase change filter element is made of disodium hydrogen phosphate dodecahydrate, hydroxyethyl cellulose, alkyl glycosides, and acidic silica sol. Combined with the room temperature catalyst Au/Fe2O3 catalytic filtration section, temperature control and efficient removal of carbon monoxide are achieved.
It achieves precise control of flue gas temperature to room temperature and efficiently catalytically removes carbon monoxide at room temperature, improving smoking comfort and filtration effect.
