Detailed description of the invention
In order better to understand the utility model, below in conjunction with specific embodiments and the drawings, the utility model is conducted further description.
The utility model relates to the empty blender of a kind of ammonia, is applicable to but is not limited to the production technical field of rare nitric acid.Please refer to Fig. 1, this blender mainly comprises housing 2, urceolus 4, and inner core 3, and be arranged on one-level vane sheet 8 and the secondary rotary blade 9 of housing 2 inside.
One end of housing 2 is provided with air intlet 1, and the other end is provided with mixer outlet 10, is the main part that ammonia and air mix between air intlet 1 and mixer outlet 10.
Between described urceolus 4 barrels and inner core 3 barrels, form a circular passage, air enters in this circular passage from air intlet 1; Between described housing 2 inwalls and urceolus 4 barrels, form a chuck.Between inner core 4 and urceolus 3, be connected by 4 communicating pipe 11, and on the two barrel, be provided with spray ammonia hole, on inner core 4 barrels, be provided with inner core spray ammonia hole 7, on urceolus 3 barrels, be provided with urceolus spray ammonia hole 6.
One preferred embodiment in, on inner core barrel, have 7 rows and spray ammonia hole, aperture 4mm, adjacent two row be staggered in arrangement.On urceolus barrel, have 8 rows and spray ammonia hole, aperture 4mm, along the circumferential direction uniform.
On housing 2, be provided with a gas ammonia import 5, described gas ammonia import 5 is connected with described chuck, and ammonia enters in this chuck from gas ammonia import 5, by entering communicating pipe 11 in inner core 3, mixes with air via inner core spray ammonia hole 7 and 8 ejections of urceolus spray ammonia hole.
Please refer to Fig. 3 and Fig. 4, the inside of housing 2 is provided with one-level vane sheet 8 and secondary rotary blade 9, and the two all has 3 vane sheets.Blade adopts arc-shaped structure, blade arc radius 450mm, width of blade 402mm, 30 ° of blade and housing axis angles.
The empty blender of this ammonia adopts jacket structured, external air enters in the circular passage between inner core 3 and urceolus 4 from air intlet 1, external gas ammonia enters in the chuck between housing 2 and urceolus 4 from gas ammonia import 5, and via communicating pipes 11 part enter in inner core 3.Gas ammonia sprays into air from inner core spray ammonia hole 7 and urceolus spray ammonia hole 8 respectively, completes preliminary mixed process.
