The invention relates to an energy-saving and environment-friendly hot air casting furnace, and belongs to the field of metal smelting equipment. The energy-saving and environment-friendly hot air casting furnace comprises a hot air casting furnace body, an air inlet and a waste gas port are formed in the hot air casting furnace body, a hot air device is connected to the air inlet and comprises an air supply pipeline, a hot air box and a fan, the fan is connected with the air inlet of the hot air casting furnace body through the air supply pipeline, the air supply pipeline penetrates through the interior of the hot air box, the hot air box is used for heating air in the air supply pipeline, a waste gas opening of the hot air box communicates with a waste gas pipeline, and the end, away from the hot air casting furnace body, of the waste gas pipeline communicates with the hot air box. According to the energy-saving and environment-friendly hot air casting furnace, the waste gas is used as fuel of the hot air box, the waste gas is fully utilized, energy consumption is reduced, and pollution to the environment is reduced.
Description
technical field [0001] The application relates to the field of metal smelting equipment, in particular to an energy-saving and environment-friendly hot blast casting furnace. Background technique [0002] The energy-saving and environment-friendly hot air casting furnace is a shaft furnace counter-flow reactor, which forms heat exchange through the downward flow of the furnace charge and the upward flow of high-temperature reducing gas, so that the charge is heated and reduced to iron and waste slag. The heat source of the energy-saving and environment-friendly hot air casting furnace mainly comes from the combustion of coke, which produces high-temperature reducing gas, which provides heat and chemical energy for the smelting of the hot air casting furnace. Various raw materials undergo complex physical and chemical reactions in the furnace. With the effect of high temperature and high pressure. Energy-saving and environment-friendly hot air casting furnace smelting air is...
