Technical Field
[0001] The utility model relates to the technical field of metal smelting environmental protection equipment, in particular to a trousers-type mixing structure used for metal smelting fume treatment. Background Art
[0002] At present, some old factories have a long history of construction, and the exhaust and steam system treatment facilities are huge and the treatment process is long. With the increasingly stringent environmental protection standards, the types and amounts of flue gas that need to be treated are also increasing. If a new mixing chamber is built directly, it will take a long time and occupy a large amount of available area in the factory, and it will involve equipment structure and greatly increased investment. Therefore, a simple flue mixing technology is needed to allow several gases to be combined and transported together, so as to upgrade the smoke dust transportation at the lowest cost.

[0005] Furthermore, the Australian stove flue composite body in the utility model is a hollow cavity, in which an Australian stove flue composite body is provided with an Australian stove flue stop valve; the roof smoke exhaust composite body is also a hollow cavity, in which a roof flue stop valve is provided.
[0006] Furthermore, the main Australian furnace flue described in the utility model is connected to the first Australian furnace flue and the second Australian furnace flue through a three-way pipe; the main roof exhaust duct is connected to the first converter plant roof exhaust duct and the second converter plant roof exhaust duct through another three-way pipe.

[0008] Furthermore, the main furnace flue and the main roof exhaust duct described in the utility model together with the main exhaust gas pipe form a trousers-like shape.
[0009] The utility model mixes several different flue gases on site when in use, thus overcoming the problem of geographical limitation and effectively avoiding the separate construction of a bulky and complex mixing chamber. Small amounts of flue gases are first merged one by one, and finally converged into two flue gases, which are mixed using a trousers-type flue structure, thereby achieving the purpose of simple mixing and common conveying of flue gases, saving floor space and investment, simplifying the smoke conveying structure and reducing conveying resistance, and having very good practical use and promotion value.
