Description

Technical Field

[0001] The utility model relates to the field of water system sampling, in particular to a novel water system chemical instrument sampling device. Background Art

[0002] Water systems are very common in various industrial production processes, such as water supply systems, cooling water systems, and fire water systems. There are many types of chemical instruments for water quality monitoring in water systems, such as PH, ORP, and conductivity. The quality of water has a profound impact on the system. Taking the cooling water system in a thermal power plant as an example, if the main parameters such as conductivity and pH value are not strictly controlled, it may lead to malicious events such as generator coil corrosion and stator blockage, and even directly cause generator failure and a significant reduction in service life. Therefore, it is crucial to ensure the accuracy and stability of chemical instrument measurements.

[0003] At present, most chemical instruments in water systems insert measuring electrodes directly into pipes or measuring pools. There are common problems such as flow velocity and bubbles interfering with measurement, and scouring accelerating electrode wear. Specifically, flow velocity and bubbles will interfere with measurement, and scouring will accelerate electrode wear. Since measuring electrodes are usually directly inserted into pipes or measuring pools, they will be affected by water flow rate, resulting in unavoidable measurement errors, and these errors are difficult to compensate for and correct by other measurement parameters.

[0004] At the same time, there are often bubbles of different sizes in the water system, which interfere with the accuracy of the measurement. If the measuring electrode is installed at the top, the impact will be more serious due to the relatively large amount of bubbles in the upper part. In addition, since the pipe diameter in the water system is generally small and the flow rate is fast, the electrode will be obviously scoured, which greatly reduces the service life of the electrode. The wear of the electrode will also cause measurement deviations.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0006] In view of the problems in the related technology, the utility model proposes a novel water system chemical instrument sampling device to overcome the above technical problems existing in the existing related technology.

[0007] To this end, the specific technical solutions adopted by the utility model are as follows:

[0008] A novel water system chemical instrument sampling device comprises a sampling cube, a liquid inlet pipe is arranged on one side of the sampling cube, a regulating valve is arranged on the outside of the liquid inlet pipe, a filter element is arranged inside the liquid inlet pipe, a partition component and a chemical instrument electrode are arranged inside the sampling cube, a liquid outflow port is arranged on the outside of the top of the sampling cube, and a pretreatment component and a partition are arranged on the bottom of the sampling cube.

[0009] Furthermore, in order to ensure that there is enough space to separate different flow rate areas so that the water flow can be gradually decelerated when passing through the partition component, the sampling cube has a square structure and a size of 50cm*50cm*10cm.

[0010] Furthermore, in order to enable natural circulation through the fluid differential pressure through partition one, partition two and partition three, and ensure real-time update of sampling, and due to the adjustment of the intervals between partition one, partition two and partition three, the caliber of the water flow increases, and the flow rate gradually slows down after layers of circuitous buffering inside. When it flows to the chemical instrument electrode, the flow rate has been significantly alleviated, greatly reducing the influence of the flow rate on the measurement and service life of the chemical instrument electrode, the partition assembly includes partition one arranged at the bottom of the sampling cube, the distance between partition one and the partition is 7.5 cm, partition two is arranged on the top of partition one, and the distance between partition one and partition two is 10 cm; partition three is arranged on the top of partition two, and the distance between partition two and partition three is 12.5 cm, the chemical instrument electrode is installed between partition two and partition three, and the distance between partition three and the top of the sampling cube is 15 cm.

[0011] Furthermore, in order to enable the three groups of mesh plates with successively decreasing apertures to form a barrier to the bubbles in the water flow, so that the larger bubbles are squeezed and collided at mesh plate one, mesh plate two and mesh plate three to be transformed into smaller bubbles, the contact area is effectively reduced, laying the foundation for the subsequent flow to the sampling cube, and preventing the bubbles in the water flow from floating up with the flow and increasing the interference with the measurement, the pretreatment component includes mesh plate one installed at the bottom end of the partition, mesh plate one is provided on one side of mesh plate one, and mesh plate three is provided on one side of mesh plate two; mesh plates one, mesh plate two and mesh plate three are all provided with mesh holes, and the apertures of the mesh holes on mesh plates one, mesh plate two and mesh plate three are successively reduced.

[0014] 2. The utility model forms a natural circulation by setting a partition assembly and utilizing the fluid differential pressure obtained by partition one, partition two and partition three, thereby ensuring real-time update of sampling. Moreover, due to the adjustment of the intervals between partition one, partition two and partition three, the caliber through which the water flows increases gradually, and the flow rate gradually slows down after layers of circuitous buffering inside. When it flows to the chemical instrument electrode, the flow rate has been significantly alleviated, thereby greatly reducing the influence of the flow rate on the measurement and service life of the chemical instrument electrode.

The utility model sets a pre-treatment component so that three groups of mesh plates with successively decreasing apertures can form a barrier to the bubbles in the water flow, and convert the larger bubbles into smaller bubbles by squeezing and impacting at mesh plates one, two and three, thereby effectively reducing the contact area, laying the foundation for the subsequent flow to the sampling cube, and preventing the bubbles in the water flow from floating up with the flow and increasing the interference with the measurement.

[0025] In one embodiment, for the above-mentioned sampling cube 1, the sampling cube 1 is a square structure and has a size of 50cm*50cm*10cm, so as to ensure that there is enough space to separate different flow rate areas, so that the water flow can be gradually decelerated when passing through the partition component 5.

[0026] In one embodiment, for the partition assembly 5, the partition assembly 5 includes a partition 1 501 arranged at the bottom of the sampling cube 1, the distance between the partition 1 501 and the partition 9 is 7.5 cm, the top of the partition 1 501 is provided with a partition 2 502, and the distance between the partition 1 501 and the partition 2 502 is 10 cm; the top of the partition 2 502 is provided with a partition 3 503, and the distance between the partition 2 502 and the partition 3 503 is 12.5 cm, the chemical instrument electrode 6 is installed between the partition 2 502 and the partition 3 503, and the distance between the partition 3 503 and the top of the sampling cube 1 is 12.5 cm. The distance is 15cm, and the sizes of partition one 501, partition two 502 and partition three 503 are all 40cm*10cm, so that a natural circulation can be formed through the fluid differential pressure through partition one 501, partition two 502 and partition three 503, ensuring real-time update of sampling, and due to the adjustment of the intervals between partition one 501, partition two 502 and partition three 503, the caliber of the water flow increases gradually, and the flow rate will gradually slow down after layers of circuitous buffering inside. When it flows to the chemical instrument electrode 6, the flow rate has been significantly alleviated, greatly reducing the influence of the flow rate on the measurement and service life of the chemical instrument electrode 6.

[0027] In one embodiment, for the above-mentioned pretreatment component 8, the pretreatment component 8 includes a mesh plate 1 801 installed at the bottom end of the partition plate 9, a mesh plate 2 802 is arranged on one side of the mesh plate 1 801, and a mesh plate 3 803 is arranged on one side of the mesh plate 2 802; mesh plates 1 801, 802 and 803 are all provided with mesh holes 804 inside, and the apertures of the mesh holes 804 on the mesh plates 1 801, 802 and 803 decrease in sequence. Specifically, the aperture of the mesh hole 804 on the mesh plate 1 801 is 1- 1.5mm, the aperture of the mesh 804 on the second mesh plate 802 is 0.5-1mm, and the aperture of the mesh 804 on the third mesh plate 803 is 0.1-0.5mm, so that the three groups of mesh plates with decreasing apertures can form a barrier to the bubbles in the water flow, so that the larger bubbles are squeezed and collided at the mesh plates 1 801, 802 and 803 to be transformed into smaller bubbles, effectively reducing the contact area, laying the foundation for the subsequent flow to the sampling cube 1, and preventing the bubbles in the water flow from floating up with the flow and increasing the interference with the measurement.

[0028] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0029] In actual application, water flows into the interior of the sampling cube 1 through the liquid inlet tube 2. Before entering the interior of the sampling cube 1, the water sample is filtered by the filter element 4 to reduce the probability of electrode contamination and scaling and impurities clogging the pipeline. After entering the sampling cube 1, the bubbles in the water flow are blocked by the pretreatment component 8, and the larger bubbles are squeezed and impacted at the mesh plate 1 801, the mesh plate 2 802 and the mesh plate 3 803 to be converted into smaller bubbles. The smaller bubbles flow into the interior of the sampling cube 1 with the water flow. Under the action of the three groups of partitions of the partition component 5, the water flow enters from the lower end and is discharged upward through 4 turns. The chemical instrument electrode 6 is located on the fourth layer. When it flows to the chemical instrument electrode 6, the flow velocity has been significantly alleviated, which greatly reduces the influence of the flow velocity on the measurement and service life of the chemical instrument electrode 6. In addition, the smaller bubbles in the water sample float up with the flow, further weakening the interference of the bubbles on the measurement.

[0030] In summary, with the help of the above technical solution of the utility model, the utility model has a simple structure and is easy to operate. By installing a filter element 4 and a regulating valve 3 with adjustable flow at the liquid inlet pipe 2, it can not only filter the water sample, reduce the probability of electrode contamination and scaling, and impurities blocking the pipeline, but also adjust the opening to keep the water sample flow in a relatively stable range, thereby achieving the purpose of optimizing sampling. The utility model sets a partition component 5 to form a natural circulation by using the fluid differential pressure obtained by partition 1 501, partition 2 502 and partition 3 503, thereby ensuring real-time update of sampling. Moreover, due to the adjustment of the interval between partition 1 501, partition 2 502 and partition 3 503, the caliber through which the water flows increases, and the internal flow is buffered layer by layer, and the flow rate gradually slows down. When it flows to the chemical instrument electrode 6, the flow rate has been significantly alleviated, greatly reducing the influence of the flow rate on the measurement and service life of the chemical instrument electrode 6. The utility model sets a pre-processing component 8 so that three groups of mesh plates with successively decreasing apertures can form a barrier to the bubbles in the water flow, and convert larger bubbles into smaller bubbles by squeezing and impacting at mesh plate 1 801, mesh plate 2 802 and mesh plate 3 803, thereby effectively reducing the contact area, laying the foundation for the subsequent flow to the sampling cube 1, and preventing the bubbles in the water flow from floating up with the flow and increasing the interference with the measurement.
