According to the technical scheme, a compressor is communicated with a carbon dioxide battery limit through a first pipeline, the carbon dioxide battery limit is communicated with a carbon dioxide main pipeline through a second pipeline, an air main pipeline is communicated with the gasifier through a third pipeline, and the carbon dioxide main pipeline is communicated with the third pipeline through a fourth pipeline; and a battery limit control valve is arranged on the second pipeline, and an air adjusting valve is arranged on the third pipeline. The blending combustion device is mainly applied to the blending combustion of the carbon dioxide.
Description
Technical field
The utility model relates to a kind of carbon dioxide recovery use device, is 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 the air, has not only caused environmental pollution, the wasting of resources, has also increased workshop consumption indirectly.
The utility model content
The deficiency that the utility model customer service prior art exists, technical problem to be solved have provided 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 scheme that the utility model adopts is: a kind of carbon dioxide recovery vapourizing furnace mingled burning installation, comprise: compressor, carbonic acid gas battery limit (BL), air main line, gentleization of the total pipeline of carbonic acid gas stove, described compressor is connected with the carbonic acid gas battery limit (BL) by first pipeline, the carbonic acid gas battery limit (BL) is connected by the total pipeline of second pipeline and carbonic acid gas, the air main line is connected with vapourizing furnace by the 3rd pipeline, and the total pipeline of described carbonic acid gas is connected with the 3rd pipeline by the 4th pipeline;
Described second pipeline is provided with the battery limit (BL) control valve, and the 3rd pipeline is provided with air control valve.
Described second pipeline, the 3rd pipeline and the 4th pipeline are provided with safety valve.
Described the 4th pipeline is provided with stopping valve.
The beneficial effect that the utility model compared with prior art has is: the utility model is mixed burning by the carbon dioxide recovery that the urea production workshop is more than needed to vapourizing furnace, and is energy-saving and cost-reducing, reduced the pollution to environment.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is schematic flow sheet of the present utility model.
Among the 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 total pipeline of carbonic acid gas, 5 is vapourizing furnace, and 6 is first pipeline, and 7 is 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.
Embodiment
As shown in Figure 1, a kind of carbon dioxide recovery vapourizing furnace mingled burning installation, comprise: compressor 1, carbonic acid gas battery limit (BL) 2, air main line 3, the total pipeline 4 of carbonic acid gas and vapourizing furnace 5, described compressor 1 is connected with carbonic acid gas battery limit (BL) 2 by first pipeline 6, carbonic acid gas battery limit (BL) 2 is connected by the total pipeline 4 of second pipeline 7 and carbonic acid gas, air main line 3 is connected with vapourizing furnace 5 by the 3rd pipeline 8, and the total pipeline 4 of described carbonic acid gas is connected with the 3rd pipeline 8 by the 4th pipeline 9;
Described second pipeline 7 is provided with battery limit (BL) control valve 10, the three pipelines 8 and is provided with air control valve 11.
Described second pipeline 7, the 3rd pipeline 8 and the 4th pipeline 9 are provided with safety valve.
Described the 4th pipeline 9 is provided with stopping valve 12.
When the utility model specifically uses, because in the urea production process, the direct urea synthesis under high-temperature and high-pressure conditions with carbonic acid gas and liquefied ammonia, the high-pressure carbon dioxide of unnecessary compressed machine compression directly is discharged in the air, by being recovered to vapourizing furnace, unnecessary high-pressure carbon dioxide mixes burning, after the carbonic acid gas step-down of compressor 1 with high pressure, be transported to carbonic acid gas battery limit (BL) 2 by first pipeline 6 and carry out the step-down gasification, open battery limit (BL) control valve 10 carbonic acid gas is transported to the total pipeline 4 of carbonic acid gas, air main line 3 is connected with vapourizing furnace 5 by the 3rd pipeline 8, the total pipeline 4 of carbonic acid gas is connected with the 4th pipeline 8 by the 4th pipeline 9, carbonic acid gas is blended into and enters vapourizing furnace 5 in the airline and mix burning, air control valve 11 on the 3rd pipeline 8 is used for regulating the air flow quantity that enters vapourizing furnace 5, and the stopping valve on the 4th pipeline 9 is used for adjusting the carbon dioxide flow that enters airline.Safety valve on the pipeline is used for adjusting pipeline air pressure, guarantees safe operation, by with the carbon dioxide recovery utilization, has significantly reduced emission of carbon-dioxide, and is energy-saving and cost-reducing, reduces the pollution to environment.
By reference to the accompanying drawings embodiment of the present utility model has been done detailed description above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skills possess, can also under the prerequisite that does not break away from the utility model aim, make various variations.
