Technical field
The present invention relates to a kind of carbon dioxide recovery use device, be specifically related to a kind of carbon dioxide recovery vapourizing furnace mingled burning installation.
Background technology
At present, the production of urea is direct urea synthesis under high-temperature and high-pressure conditions with carbonic acid gas and liquefied ammonia, the high-pressure carbon dioxide of the compressed machine compression that part is more than needed directly is discharged in air, has not only caused environmental pollution, the wasting of resources, has also indirectly increased workshop consumption.
Summary of the invention
The deficiency that customer service prior art of the present invention exists, technical problem to be solved have been to provide and a kind ofly unnecessary high-pressure carbon dioxide can be recovered to the carbon dioxide recovery vapourizing furnace mingled burning installation that vapourizing furnace is mixed burning.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: carbon dioxide recovery vapourizing furnace mingled burning installation, comprise: compressor, carbonic acid gas battery limit (BL), air main line, carbonic acid gas main pipe line and vapourizing furnace, described compressor is connected with the carbonic acid gas battery limit (BL) by the first pipeline, the carbonic acid gas battery limit (BL) is connected with the carbonic acid gas main pipe line by the second pipeline, the air main line is connected with vapourizing furnace by the 3rd pipeline, and described carbonic acid gas main pipe line is connected with the 3rd pipeline by the 4th pipeline;
Be provided with the battery limit (BL) control valve on described the second pipeline, be provided with air control valve on the 3rd pipeline.
Described the second pipeline, the 3rd pipeline and the 4th pipeline are provided with safety valve.
Be provided with stopping valve on described the 4th pipeline.
The beneficial effect that the present invention compared with prior art has is: the present invention is by urea production workshop carbon dioxide recovery more than needed is mixed burning to vapourizing furnace, and is energy-saving and cost-reducing, reduced the pollution to environment.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is schematic flow sheet of the present invention.
In figure: 1 is that compressor 1,2 is the carbonic acid gas battery limit (BL), and 3 is the air main line, and 4 is the carbonic acid gas main pipe line, 5 is vapourizing furnace, and 6 is the first pipeline, and 7 is the second pipeline, and 8 is the 3rd pipeline, 9 is the 4th pipeline, and 10 is the battery limit (BL) control valve, and 11 is air control valve, and 12 is stopping valve.
