[0001] The utility model belongs to the technical field of caprolactam production, and relates to a steam tracing device for industrial sampling. Background Technique
[0002] In the process of industrial production, accurate sampling and analysis of fluids (including gases and liquids) are not only the key to ensuring product quality and optimizing the production process, but also an important cornerstone for realizing the automation of process control. Under low-temperature conditions, the viscosity of fluids increases, and their fluidity significantly decreases, making it extremely easy to form blockages or solidifications in the sampling pipelines, resulting in unsmooth or even complete interruption of sampling. This not only affects the timeliness and accuracy of sampling data, but may also cause a series of reactions such as pipeline corrosion and equipment damage due to fluid retention, increasing the operating costs and risks of enterprises.

An analyzer 5 is arranged inside the analysis pretreatment box 4 and communicates with the sampling pipe 6.

[0027] Preferably, after the steam flows through the analysis pretreatment box 4, it continues through the integrated steam tracing pipe 7 to the sampling port of the process pipeline 9 and then the tracing pipe 1 communicates with the underground discharge port to prevent excess steam from accumulating at the sampling port.

By adjusting the opening degree of the pneumatic control valve 2, precise control of the temperature in the tracing pipe 1 can be achieved.
[0029] Working principle:
[0030] As Figure 1 shown, for sampling input, an analysis pretreatment box 4 and a process pipeline 9 are provided on-site. There is a sampling flange on the process pipeline 9, which is connected to a threaded joint 8. The other end of the threaded joint 8 is used to connect the sampling pipe 6 in the integrated steam tracing pipe 7. The fluid enters the analyzer 5 in the analysis pretreatment box 4 through the sampling pipe 6 and then enters the final analysis and monitoring equipment after passing through the analyzer 5;
[0031] Steam input: Connect the gas source of the on-site device through the steam inlet on the left side. Introduce the steam heat into the tracing pipe 1 through the pneumatic control valve 2. A remote thermometer 3 is provided on the tracing pipe in the analysis pretreatment box. The temperature in the tracing pipe is controlled through the control valve on the DCS.
[0032] The tracing pipe is fixed spirally in the analysis pretreatment box 4 to provide a suitable temperature environment inside the whole box. After the steam flows through the analysis pretreatment box, it continues through the integrated steam tracing pipe to the sampling port of the process pipeline. To prevent excess steam from accumulating at the sampling port, the tracing pipe is diverted to the underground discharge port on-site.
[0033] As Figure 2 shown, in this integrated steam tracing pipe, the tracing pipe 1 is closely attached to the sampling pipe 6. Through the circulating flow of steam, the fluid in the sampling pipe is heated to prevent it from solidifying or increasing in viscosity in a low-temperature environment, thus ensuring the smooth flow and temperature stability of the fluid. The heating tape 102 wraps the tracing pipe and the sampling pipe. To further enhance the heat preservation effect, the heat preservation material fiberglass wool 103 is filled in the outer sheath 101, enabling the tracing system to maintain an efficient heating and heat preservation effect for a long time, thereby ensuring the temperature stability of the fluid in the sampling pipe and the accuracy of measurement.
