The immersion tube bank mixing top-blown spray gun of the present invention includes tube bank mixing section 1, it is arranged on mixing section 1 top or annular more than three lateral identical multi-fluid interfaces 2, section 3 straight-through with the fluid-mixing that tube bank mixing section 1 is connected, be connected with the straight-through section 3 of fluid-mixing its inside be equipped with the eddy flow section 4 of a cyclone, one end is connected with eddy flow section 4, the hollow turbulent flow section 5 of other end opening。Wherein:
The length of described tube bank mixing section 1 is more than 25mm, and the inside of tube bank mixing section 1 is mixed tube bundle version。
Described each interface diameter being arranged on mixing section 1 top or annular more than three lateral identical multi-fluid interfaces 2 is more than or equal to 6mm。
The described straight-through section 3 of the fluid-mixing being easy to for lengthening spray gun reach in metallurgical furnace is a circular spray gun urceolus, and length is more than or equal to 1000mm。
The length of the described cyclone within eddy flow section 4 is 200mm to 2000mm, and the length of eddy flow section 4 is less than 2500mm。
Described turbulent section 5 is one layer of spray gun urceolus, and length is less than or equal to 1500mm。
The immersion tube bank mixing top-blown spray gun of the present invention, market the part bought (cyclone) and material are prepared according to a conventional method。
The beneficial effects of the present invention is:
1, simple in construction, easily manufactured, intensity of cooling are big, and the life-span is long。
2, achieve multiple fluid to mix in spray gun, improve the production efficiency of non-ferrous metal metallurgy。
3, turbulent flow section 5 can be immersed in molten bath for stirring metallurgical bath, makes metallurgical bath Accelerative mass transfer, heat transfer, improves efficiency, also can be parked in above liquid state molten pool。Turbulent flow section 5 is one layer of pipeline, when imbedding in pyrometallurgy container loss and being a part of, only end equating, need to again connect the preceding paragraph, can come into operation again, be substantially reduced metallurgical operating cost。
4, according to different metallurgical technology atmosphere requirements, regulate the different pressure of the fluid of each medium entrance spray gun mixing head, flow, to generate different atmosphere and different pyrometallurgy temperature requirements, meeting different metal and smelt required atmosphere requirements, range of accommodation is wide。
Accompanying drawing illustrates:
Accompanying drawing is the structural representation of the present invention。
Detailed description of the invention:
The immersion tube bank mixing top-blown spray gun of the present invention includes tube bank mixing section 1, it is arranged on mixing section 1 top or annular more than three lateral identical multi-fluid interfaces 2, section 3 straight-through with the fluid-mixing that tube bank mixing section 1 is connected, be connected with the straight-through section 3 of fluid-mixing its inside be equipped with the eddy flow section 4 of a cyclone, one end is connected with eddy flow section 4, the hollow turbulent flow section 5 of other end opening。Wherein:
The length of described tube bank mixing section 1 is more than 25mm, and the inside of tube bank mixing section 1 is mixed tube bundle version。
Described each interface diameter being arranged on mixing section 1 top or annular more than three lateral identical multi-fluid interfaces 2 is more than or equal to 6mm。
The described straight-through section 3 of the fluid-mixing being easy to for lengthening spray gun reach in metallurgical furnace is a circular spray gun urceolus, and length is more than or equal to 1000mm。
