Description

Technical Field

[0001] The utility model provides a heat dissipation device for a heating section of a light-burned magnesia rotary kiln, belonging to the technical field of energy-saving of the light-burned magnesia rotary kiln. Background Art

[0002] The light-burned magnesia rotary kiln is a key equipment for the production of light-burned magnesia. The calcination temperature of light-burned magnesia is usually between 700-1000 degrees. The rotary kiln is usually combined with a burner to transfer heat energy to magnesium oxide by burning high-temperature gas, causing the magnesium oxide to undergo chemical changes and convert into light-burned magnesium oxide. However, the temperature of the steel shell of the kiln body in the heating section close to the burner is too high, which can easily cause damage to the kiln body. This patent proposes to install a copper heat pipe wrapped around the heating section of the rotary kiln. The copper material has strong thermal conductivity, high strength and toughness, and can work normally in an environment with a melting point below 1083 degrees. It fits the working environment of the light-burned magnesia rotary kiln and solves the problem of overheating in the heating section of the rotary kiln. Utility Model Content
