[0001] The utility model relates to the field of hot blast stove tail gas treatment, and more specifically to a hot blast stove with a tail gas recovery function. Background Art

[0002] Hot blast furnace is a thermal power machine. It began to be widely used in my country in the late 1970s. It has become a replacement product for electric heat source and traditional steam power heat source in many industries. There are many varieties and series of hot blast furnaces. They are divided into manual burning and machine burning according to the coal adding method, and divided into coal, oil, gas furnaces, etc. according to the type of fuel.

[0003] Based on the above, the inventors have found that most of the existing hot blast furnaces may directly filter and discharge the exhaust gas after recovering it, so that the exhaust gas that is not fully cooled and filtered contains more impurities, which may cause certain pollution to the atmosphere and easily cause damage to the pipeline. Therefore, in view of this, the existing structure is studied and improved to provide a hot blast furnace with exhaust gas recovery function, in order to achieve a more practical purpose.
