The invention discloses a dioxin emission reduction waste heat recovery system. The system comprises a furnace body, a first induced draft fan, a combustion chamber, a combustor and an environment-friendly flue; the input end of the first induced draft fan is connected with the furnace body, the output end of the first induced draft fan is connected with the combustion chamber, and the first induced draft fan is used for introducing flue gas generated in the furnace body into the combustion chamber; the combustor is connected with the combustion chamber, wherein the output end of the combustoris extended into the combustion chamber; and the combustion chamber is connected with the environment-friendly flue. The dioxin emission reduction waste heat recovery system is applied to a molten aluminum furnace, and can reduce dioxin components in the flue gas generated in the incineration process of crushed materials such as aluminum pins, broken aluminum materials and cans.
Description
technical field [0001] The invention relates to the technical field of aluminum smelting technology, in particular to a waste heat recovery system for dioxin emission reduction. Background technique [0002] Aluminum melting furnace is a new type of high-efficiency energy-saving furnace developed according to the aluminum smelting process. In addition to the conventional aluminum ingot feeding port, there is also a small feeding port on the existing aluminum melting furnace body, which is used to adjust the furnace body. Throw in scraps such as aluminum pins, broken aluminum, and cans for incineration. The problem caused by this structure is: due to the extremely high temperature in the hearth of the aluminum melting furnace, when the scraps such as aluminum pins, broken aluminum materials, and pop cans are put into the aluminum melting furnace through the small feeding port, the organic matter such as oil stains on the scraps It will conduct incomplete combustion in an ins...
