Description

Technical Field

[0001] The utility model relates to the technical field of steam quality testers, in particular to a continuous real-time steam quality tester. Background Art

[0002] In modern industrial production, steam, as an important heat energy carrier and power source, its quality directly affects production efficiency and product quality. Therefore, accurately and efficiently testing steam quality has become a key link in ensuring production safety and improving economic benefits. As the core equipment to achieve this goal, the performance of the steam quality tester is directly related to the reliability and accuracy of the test results. However, in the existing design of steam quality testers, especially in the part using Dewar flasks as sample containers, there are some technical bottlenecks that limit the test efficiency and the accuracy of the results, mainly reflected in the following aspects:

[0003] The uniformity problem of the sample is one of the important factors affecting the test accuracy. After collecting the steam sample, if the inside of the Dewar flask is not shaken sufficiently in the traditional steam quality tester, it is easy to cause the non-uniform spatial distribution of the sample components. This non-uniformity not only stems from the phase change during the natural cooling process of the steam, but also is closely related to the Dewar flask structure and the sampling method. The non-uniformity of the sample will directly lead to deviations in the test results and it is difficult to truly reflect the actual quality status of the entire steam system.

[0004] The non-uniformity of temperature control is another technical problem that cannot be ignored. As a heat-insulating container, the Dewar flask is designed to maintain a constant temperature of the sample for a long time. However, a Dewar flask lacking an effective shaking mechanism often forms a temperature gradient inside, especially more significant in large-capacity or complex-shaped Dewar flasks. This temperature difference will further exacerbate the non-uniform distribution of the sample components, and may also cause changes in the reaction rates of certain chemical reactions, affecting the comparability and repeatability of the test data.

[0005] The prolongation of the phase change process is a direct manifestation of the low efficiency of sample processing. Inside the Dewar flask that has not been shaken sufficiently, the process of steam converting to liquid may become slow due to locally low temperature or unstable gas-liquid interface. This not only delays the test process, but may also cause the aggregation of some insoluble impurities during the steam condensation process, further affecting the accuracy of the test results.

[0006] The problem of gas solubility is also a factor restricting the test efficiency. Under certain specific test requirements, such as analyzing trace gas components in steam, the rapid and sufficient dissolution of gas in liquid is a prerequisite for obtaining accurate data. Inside the Dewar flask lacking effective shaking, the exchange efficiency between gas and liquid is low, and it is difficult to ensure that all gas components can dissolve according to the actual ratio, thus affecting the comprehensive evaluation of steam quality.

[0007] The existence of the wall attachment effect cannot be underestimated either. When steam condenses or the sample accumulates on the wall of the Dewar flask, it not only reduces the amount of the sample for effective testing, but may also cause inconsistencies in the composition between the wall and the internal solution. Such inconsistencies will be directly reflected in the final test data, resulting in distorted analysis results.

[0008] Problems such as poor sample uniformity, uneven temperature, prolonged phase change process, low gas dissolution efficiency, and wall attachment effect caused by the non-shaking of the Dewar flask in existing steam quality testers have become important obstacles restricting the progress of steam quality detection technology.

[0009] Therefore, how to provide a continuous real-time steam quality tester is an urgent problem for those skilled in the art. Utility Model Content

[0028] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model

[0029] Please refer to Figures 1 to 5 , the present utility model provides a continuous real-time steam quality tester, including a threaded rod 1, a steam power assembly 2, a swing assembly 3 and a clamping assembly 4. Among them, the top of the threaded rod 1 is fixedly installed on the steam power assembly 2. The threaded rod 1 is convenient to be connected to a workbench or a triangular bracket.

[0032] More specifically, the swing assembly 3 includes a connecting plate 3.1, a power groove 3.2, a first tooth group 3.3, and a second tooth group 3.4. Among them, the connecting plate 3.1 is fixedly installed on the steam pipe 2.1, and the connecting plate 3.1 is arranged in a curved shape.

[0035] Furthermore, when detecting the dryness value in the steam quality, the steam pipe 2.1 is connected to the intermediate gas pipe through the steam connection pipe 2.2 to connect the steam delivery pipe. An electric valve switch is added to the intermediate gas pipe. The steam connection pipe of the Dewar flask 5 is connected to the steam delivery pipe.

[0036] First, threadedly connect the threaded rod 1 to the workbench or the triangular bracket for fixation.

[0037] Place the Dewar flask 5 in the clamping cylinder 4.1. Rotate the torsion rod 4.5. The torsion rod 4.5 drives the screw rod 4.2 to rotate.

[0038] Numerically control the switch of the electric valve. When it is opened, the steam delivery pipe delivers steam to the steam connection pipe 2.2 through the gas pipe, and then enters the steam pipe 2.1 from the steam connection pipe 2.2. The air pressure of the steam pushes the piston plate 2.3 to slide in the steam pipe 2.1. The piston plate 2.3 drives the extension plate 2.4 to extend. The extension of the extension plate 2.4 drives the swing rod 3.7 to move. The movement of the swing rod 3.7 drives the swing gear 3.8 to displace. The swing rod 3.7 slides in the chute 3.6. The displaced swing gear 3.8 passes through the first tooth group 3.3 and the second tooth group 3.4, driving the swing gear 3.8 to rotate. The swing gear 3.8 drives the swing rod 3.7 to rotate. Continuously passing through the first tooth group 3.3 and the second tooth group 3.4, the swing gear 3.8 swings left and right. The swing gear 3.8 drives the swing rod 3.7 to swing left and right. The left and right swing of the swing rod 3.7 drives the Dewar flask 5 to swing left and right.

[0039] When the electric valve switch is closed and the steam in the steam pipe 2.1 leaks, it slides back into the steam pipe 2.1 for reset according to the weight of the Dewar flask 5 and the extension plate 2.4, waiting for the next detection.

[0040] Shaking the Dewar flask 5 can help mix the vapor or liquid sample inside the flask, ensuring a uniform distribution of components during sampling. This is crucial for obtaining a representative test sample and avoiding test errors caused by uneven component distribution; shaking can promote temperature uniformity inside the flask and reduce local temperature differences, which is particularly important for vapor quality tests that require precise temperature control; the test involves phase change processes such as vapor condensation or liquid evaporation, and appropriate shaking can accelerate this process, enabling the sample to reach a stable state faster, thereby shortening the test preparation time; shaking can reduce this wall adhesion effect and ensure that all samples can be effectively tested.

[0041] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, should be covered by the protection scope of the present utility model.
