Description

Technical Field

[0001] The utility model relates to the technical field of steam condensate samplers, in particular to a steam condensate sampler. Background Art

[0002] In the modern industrial production system, steam, as an efficient energy carrier, is widely used in heating, power generation and heat transfer processes in various fields. The efficient operation and maintenance of the steam system are directly related to multiple aspects such as production efficiency, energy consumption and even environmental impact. Among them, the management and utilization of steam condensate are a key link to ensure the long-term stable operation of the system. It not only affects the maintenance of steam quality, but also is an important way for heat energy recovery and water resource recycling. Therefore, how to accurately and effectively collect steam condensate samples to monitor its quality and evaluate the heat exchange efficiency of steam pipelines has become the core issue of concern in the industry.

[0003] The main challenge faced by traditional steam condensate sampling technology is that as steam flows in the pipeline and gradually releases heat to form condensate, its temperature shows an increasing trend from top to bottom along the axial direction of the pipeline. The existence of this temperature gradient has a complex impact on the sampling process and the cooling effect of the pipeline. Specifically, the condensate located in the upper section of the pipeline has a lower temperature due to shorter contact time with steam and is closer to the ideal distilled water state. As the water flows towards the lower part of the pipeline, affected by factors such as heat conduction from the outer wall of the pipeline and temperature rise of the surrounding environment, the water temperature gradually increases. This not only affects the purity of the condensate, but also weakens the natural cooling mechanism of the steam pipeline, posing challenges to the thermal efficiency and economy of the entire system.

[0004] Challenge of sampling accuracy. Temperature differences cause changes in the saturation and precipitation behavior of dissolved substances in the condensate, resulting in significant differences in the water quality analysis results sampled at different heights. If the sampling point is set unreasonably, it may lead to misjudgment of the overall water quality situation. Especially in industries such as food processing, pharmaceuticals and precision electronics manufacturing that require strict water quality control, such errors may directly affect product quality and production safety.

[0005] Difficulty in evaluating heat exchange efficiency. The heat exchange efficiency of the steam pipeline is closely related to the temperature distribution of the internal condensate. The non-uniformity of temperature makes it difficult to comprehensively evaluate the heat energy transfer of the entire pipeline based on single or fixed-position sampling, thus affecting the accurate judgment of system heat loss, heat efficiency improvement measures and heat recovery system design.

[0006] Pipeline maintenance and safety risks. The gradually increasing temperature of the condensate may cause scale or corrosion in some areas of the pipeline. Especially when water containing hardness components flows through the metal pipeline at a higher temperature, it accelerates the formation of the scale layer, increases the maintenance cost, and may also cause local overheating, forming a safety hazard.

[0007] Therefore, how to provide a steam condensate sampler is an urgent problem to be solved by those skilled in the art. Utility Model Content
