[0027] As Figure 1 shown, this embodiment provides a sulfur recovery analysis and measurement device, which is composed of a laser analyzer transmitting end 1, a laser analyzer receiving end 2, an inner inserted pipe 3, a transmitting end purge flange 4, a transmitting end full-bore shut-off valve 5, a receiving end full-bore shut-off valve 6, a receiving end purge flange 7, a transmitting end nitrogen purge pipeline 8, a receiving end nitrogen purge pipeline 9, a steam tracing valve 10, a steam tracing pipeline temperature probe 11, a steam tracing pipeline 12, an electric tracing device power switch 13, an electric tracing control system 14, a pipeline electric tracing tape 15, a nitrogen purge pipeline temperature probe 16, a steam component 17, an outer pipeline 18, and so on.

[0028] Laser path: laser analyzer transmitting end 1, transmitting end purge flange 4, transmitting end full-bore shut-off valve 5, steam component 17, inner inserted pipe 3, receiving end full-bore shut-off valve 6, receiving end purge flange 7, laser analyzer receiving end 2.

[0029] Nitrogen purge device: transmitting end nitrogen purge pipeline 8, receiving end nitrogen purge pipeline 9.

[0030] Steam tracing device: steam tracing valve 10, steam tracing pipeline 12, steam component 17.

[0031] Pipeline electric tracing device: transmitting end nitrogen purge pipeline 8, receiving end nitrogen purge pipeline 9, pipeline electric tracing tape 15, electric tracing control system 14, electric tracing device power switch 13, steam tracing pipeline temperature probe 11, nitrogen purge pipeline temperature probe 16.

[0032] Holes are opened at the central positions of structures such as the transmitting end purge flange 4, the transmitting end full-bore shut-off valve 5, the steam component 17, the inner inserted pipe 3, the receiving end full-bore shut-off valve 6, and the receiving end purge flange 7 as the laser path allowing the laser to pass through. The laser is emitted from the laser analyzer transmitting end 1, passes through the transmitting end purge flange 4, the transmitting end full-bore shut-off valve 5, the steam component 17, the inner inserted pipe 3, the transmitting end full-bore shut-off valve 5, and the receiving end purge flange 7, and then is received by the laser analyzer receiving end 2. The laser analyzer analyzes the laser information to analyze the sample.

[0033] The inner insert tube 33 is formed by welding concentric tubes composed of two PIPE tubes. Among them, the outer diameter of the inner tube is 20 mm, and the outer diameter of the outer tube is 40 mm, ensuring that it can be inserted into the flange bosses at both ends of the outer pipeline 18. The inner insert tube 3 welds sandwich plates on the outer wall of the inner tube and the inner wall of the outer tube, and steam can conduct heat evenly through the sandwich plates.

[0034] In this embodiment, two purge pipelines are adopted to purge the laser paths at different positions respectively.

[0035] The first purge pipeline: The nitrogen purge device outputs nitrogen, which passes through the nitrogen purge pipeline 8 at the transmitting end, reaches the purge port A1 on the purge flange 4 at the transmitting end, enters the hole (laser path) in the middle of the purge flange 4 at the transmitting end, and finally discharges from the air outlet A2 on the left side of the inner insert tube 3.

[0036] The second purge pipeline: The nitrogen purge device outputs nitrogen, which passes through the nitrogen purge pipeline 9 at the receiving end, reaches the purge port B1 on the purge flange 7 at the receiving end, enters the hole (laser path) in the middle of the purge flange 7 at the receiving end, and finally discharges from the air outlet B2 on the right side of the inner insert tube 3.

[0037] In this embodiment, steam tracing is carried out for the inner insert tube 3: The steam tracing device outputs steam, which passes through the steam tracing valve 10 and the steam tracing pipeline 12, enters from the steam inlet C1, then passes through the lower part and the upper part of the inner insert tube 3, and discharges from the steam outlet C2.

[0038] The pipeline is electrically traced by using a pipeline electric tracing device: The first part: The nitrogen purge pipeline 8 at the transmitting end and the nitrogen purge pipeline 9 at the receiving end are both electrically traced cable assemblies, maintaining the temperature at 100 - 150 °C. The temperature of the pipeline is detected by the nitrogen purge pipeline temperature probe 16. The electric tracing control system 14 sets a fixed temperature value. When the nitrogen purge pipeline temperature probe 16 is lower than the set value, the power switch of the electric tracing system is turned on to ensure the temperature of the nitrogen purge pipeline 8 at the transmitting end and the nitrogen purge pipeline 9 at the receiving end, so that the nitrogen at the purge flange is preheated, thereby reducing the steam consumption. The second part: The pipeline electric tracing tape 15 is wound around the outer wall of the inner insert tube 3. When the steam tracing pipeline temperature probe 11 detects that the temperature of the steam tracing pipeline 12 is lower than the set value, the electric tracing control system 14 turns on the power switch of the electric tracing system to ensure the temperature of the inner insert tube 3.

[0039] In this embodiment, on the one hand, through pipeline tracing, the temperature of the nitrogen purge is higher than the sample temperature, so that when nitrogen contacts the sample, condensation and crystallization will not occur; on the other hand, the instrument lens is purged with high-temperature nitrogen to ensure the cleanliness of the lens, and the dust in the pipeline is blown away by high-temperature nitrogen to ensure the cleanliness of the pipeline.

[0040] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Any person skilled in the art can, without departing from the scope of the technical solution of the present utility model, make many possible changes and modifications to the technical solution of the present utility model by using the methods and technical contents disclosed above, or modify it into equivalent embodiments with equivalent changes. Therefore, all equivalent changes made according to the shape, structure and principle of the present utility model without departing from the content of the technical solution of the present utility model shall be covered by the protection scope of the present utility model.
