Description

Technical Field

[0001] The invention belongs to the technical field of water vapor sampling and flow stabilization devices, and in particular relates to a low-temperature section water vapor sampling and flow stabilization device and system. Background Art

[0002] In the existing soda sampling rack low temperature system, the flow rate adjustment means of instrument sampling and manual sampling are relatively primitive, mainly relying on manual needle valves for manual adjustment; however, this adjustment method has many shortcomings; with the frequent changes in the unit load, the pressure in the pipeline will change significantly, causing the instrument sampling flow rate to increase or decrease; this unstable flow fluctuation will not only cause inaccuracy in instrument measurement, but in severe cases may even cause flow interruption, thereby damaging the electrode, seriously affecting the accuracy of sampling data and the long-term reliability of the equipment;

[0003] In addition, the existing soda sampling system has the problem of unstable temperature control during sampling. Due to the lack of an effective temperature regulation mechanism, it is often difficult to keep the temperature constant during sampling, which further aggravates the inaccuracy of the sampling data. In order to make up for this defect, operators often need to repeatedly sample multiple times in the hope of approaching the true value through multiple measurements, which undoubtedly greatly reduces work efficiency and increases the labor intensity of operators.

[0004] What is more serious is that due to the instability of the sampling flow and the inaccurate temperature control, the existing soda sampling system often finds it difficult to provide high-quality sampling data, which brings great trouble to subsequent analysis and decision-making; at the same time, the need for repeated sampling also increases the risk of equipment wear and failure, further affecting the stability and reliability of the system. Summary of the invention

[0005] The present invention provides a low-temperature section water vapor sampling and flow stabilization device, aiming to solve the shortcomings of the existing water vapor sampling, namely, primitive adjustment means, unstable flow and temperature control, and flow fluctuation caused by unit load changes, which affects the measurement accuracy and equipment reliability, and even causes flow interruption and damages the electrode; at the same time, the temperature is difficult to be constant, which aggravates the data inaccuracy, and multiple samplings are required to reduce efficiency and increase labor intensity. These problems lead to low quality of sampling data, affect subsequent analysis and decision-making, increase equipment wear and failure risks, and reduce system stability and reliability.

[0014] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0015] First, the present invention can efficiently cool the water vapor in the raw material pipeline and realize the effective transfer and dissipation of heat. Specifically, the cooling bin absorbs the heat in the water vapor, and then the heat circulates between the two water tanks through the water pipe, and is finally taken away by the air flow accelerated by the cooling fan and quickly dissipated into the surrounding environment. This design not only ensures that the temperature of the water vapor before sampling can be stably maintained at a moderate level, thereby greatly improving the accuracy of sampling, but also effectively extends the overall service life of the device by reducing the impact of temperature fluctuations on the thermal stress of the internal structure of the device. In addition, the stable temperature environment also reduces the risk of failures that may be caused by temperature fluctuations, further improving the reliability and stability of the device.

[0016] Secondly, the balanced flow stabilizing valve in the device of the present invention provides a constant resistance to the flow of water vapor, ensuring that no matter how the water vapor flow in the raw material pipeline fluctuates, the water vapor flow through the valve can remain stable; this feature is crucial because it ensures that the water vapor flow received by the sampling mechanism always remains constant, thereby achieving high-precision sampling; in addition, the present invention also provides a branch material pipe connected to the side of the main material pipe; this design not only simplifies the sampling process, but also significantly reduces the adverse effects that may be caused to the entire system due to equipment sampling; sampling through the branch material pipe can avoid direct interference with the water vapor flow in the main material pipe, thereby improving the working efficiency of the system and ensuring the accuracy and reliability of sampling.

[0017] Thirdly, the present invention realizes the convenient adjustment of the position of the sampling mechanism, so that a plurality of sampling tubes are aligned with the branch material pipe orifices in turn to complete the sampling work. This design not only improves the convenience of the sampling operation, but also enhances the applicability and flexibility of the sampling mechanism, and meets different sampling needs. This design makes the sampling results more reliable and helps to fully understand the quality and characteristics of water vapor.

[0018] Fourthly, the device of the present invention is equipped with a temperature sensor that can monitor the temperature changes of water vapor in real time. Once a temperature abnormality or system failure occurs, such as a temperature sensor failure or a sampling mechanism jam, the operation panel will display the fault information and trigger the buzzer alarm to sound an alarm. This design can continue to operate in a safe and stable state, and also greatly reduces the risk of production interruptions or safety accidents that may be caused by failure to discover and handle the fault in time.

[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] The embodiment of the present invention provides a low temperature section water vapor sampling and stabilizing flow device, such as Figure 1-7As shown, it includes a sampling support 1; a raw material pipeline 2 arranged in the sampling support 1; a feeding pipeline 3 is connected to the top position of the raw material pipeline 2; a first pump body 4 is arranged on the feeding pipeline 3; a feeding pipeline 5 is connected to the bottom position of the raw material pipeline 2; a sampling mechanism is arranged on the side of the feeding pipeline 5 away from the raw material pipeline 2; and a cooling mechanism is arranged at the external position of the raw material pipeline 2; wherein the cooling mechanism includes: a cooling bin 6 surrounding the outer wall of the raw material pipeline 2; a water tank 7 arranged on both sides of the cooling bin 6; the cooling bin 6 and the two water tanks 7 are connected through a water pipe 8; a second pump body 9 is arranged on both of the water pipes 8; an installation groove 22 is opened at the upper position of the two water tanks 7 on the side away from the cooling bin 6; a cooling fan 10 is arranged in the two installation grooves 22; and a plurality of heat conducting plates 11 are arranged on the side walls of the two water tanks 7 adjacent to the cooling fan 10.

[0030] It should be noted that, due to the continuous shortcomings of the existing water vapor sampling, such as primitive adjustment means and unstable flow and temperature control, the load change of the unit leads to flow fluctuations, which affects the measurement accuracy and equipment reliability, and even causes flow interruption and damage to the electrode; at the same time, the temperature is difficult to be constant, which aggravates the inaccuracy of the data. Multiple sampling is required to reduce efficiency and increase labor intensity. These problems lead to low quality of sampling data, affect subsequent analysis and decision-making, increase equipment wear and failure risks, and reduce system stability and reliability. The efficient cooling treatment of this solution ensures the temperature stability of the water vapor before sampling, and improves the accuracy of sampling; The design of the flow stabilizing valve 12 and the branch pipe 14 ensures the constancy of the water vapor flow and the simplification of the sampling process, further improving the accuracy and efficiency of sampling, while reducing the adverse effects of sampling on the overall operation of the system; the convenient adjustment of the position of the sampling mechanism enhances the applicability and flexibility of the sampling mechanism, meets different sampling requirements, makes the sampling results more reliable, and helps to fully understand the quality and characteristics of water vapor; and the real-time monitoring of the temperature sensor 25 and the provision of a fault alarm system ensure that the device continues to operate in a safe and stable state, reducing the risk of production interruptions or safety accidents due to faults.

[0031] Specifically, in this embodiment, the scheme mainly includes a sampling support 1; a raw material pipeline 2 is installed inside the sampling support 1 for transmitting water vapor to be sampled; at the top of the raw material pipeline 2, it is connected to the first pump body 4 through the feeding pipeline 3, and the first pump body 4 is responsible for pumping water vapor from the source into the raw material pipeline 2; as the water vapor flows in the raw material pipeline 2, it will be transported to the lower part of the device; at the bottom position of the raw material pipeline 2, the unloading pipeline 5 is connected thereto; a sampling mechanism is set on one side of the unloading pipeline 5, which is responsible for sampling in the stable flowing water vapor;

[0032] In order to ensure that the temperature of the water vapor is stable and moderate before sampling, a cooling mechanism is arranged outside the raw material pipeline 2; the core of the cooling mechanism is a cooling chamber 6 surrounding the outer wall of the raw material pipeline 2, which is connected to two water tanks 7 through a water pipe 8; the two water tanks 7 are respectively located on both sides of the cooling chamber 6, and a circulating water path is formed between them through the water pipe 8; a second pump body 9 is arranged on the water pipe 8 to promote the circulation of cooling water between the cooling chamber 6 and the water tank 7; when the cooling water flows through the cooling chamber 6, it absorbs the heat of the water vapor in the raw material pipeline 2, thereby reducing the temperature of the water vapor;

[0033] In order to further improve the cooling efficiency, installation grooves 22 are opened at the upper position of the two water tanks 7 on the side away from the cooling chamber 6, and cooling fans 10 are installed in these installation grooves 22; when the cooling fans 10 are started, they will accelerate the flow of air around the water tanks 7, and help to dissipate the heat in the water tanks 7 to the surrounding environment more quickly; at the same time, a number of heat conductive plates 11 are also arranged on the side walls of the two water tanks 7 adjacent to the cooling fans 10; these heat conductive plates 11 can increase the heat exchange area between the water tanks 7 and the surrounding air, thereby improving the heat dissipation efficiency.

[0034] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the sampling mechanism includes: a balanced flow-stabilizing valve 12 connected to the lower position of the discharge pipeline 5; a main material pipe 13 connected to the bottom position of the balanced flow-stabilizing valve 12; a branch material pipe 14 connected to the side of the main material pipe 13, and a flow meter 15 is arranged on the branch material pipe 14; a main check valve 16 and a branch check valve 17 are respectively arranged on the main material pipe 13 and the branch material pipe 14.

[0035] In this embodiment, the water vapor continues to flow in the raw material pipeline 2 and finally reaches the lower part of the feed pipeline 5, where a balanced flow stabilizing valve 12 is installed; the balanced flow stabilizing valve 12 provides a constant resistance when the water vapor flows through, ensuring that the water vapor flow rate passing through it maintains a stable state; therefore, no matter how the water vapor flow rate in the raw material pipeline 2 fluctuates, the balanced flow stabilizing valve 12 can ensure that the water vapor flow rate received by the sampling mechanism remains constant;

[0036] Subsequently, the stable water vapor flow regulated by the balancing and stabilizing flow valve 12 enters the main material pipe 13; in order to ensure the unidirectional flow of water vapor and prevent it from flowing back from the main material pipe 13 to the balancing and stabilizing flow valve 12 or the unloading pipeline 5, a main one-way valve 16 is specially installed on the main material pipe 13; the main one-way valve 16 strictly limits the flow direction of water vapor and only allows water vapor to flow from the balancing and stabilizing flow valve 12 to the downstream of the main material pipe 13;

[0037] A branch pipe 14 is arranged beside the main pipe 13, and its main function is to sample water vapor. In order to realize accurate flow monitoring, the branch pipe 14 is provided with a flow meter 15, which can capture and record the water vapor flow data passing through the branch pipe 14 in real time. In order to ensure the one-way flow of water vapor and prevent it from flowing back from the branch pipe 14 to the main pipe 13 or the balancing valve 12, a branch check valve 17 is also installed on the branch pipe 14. The branch check valve 17 strictly follows the flow direction of water vapor and only allows water vapor to flow from the main pipe 13 into the branch pipe 14 and pass through the flow meter 15, thereby successfully completing the sampling process. The setting of the branch pipe 14 effectively prevents the sampling operation from having adverse effects on the entire system.

[0038] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the sampling mechanism also includes: a movable base 18 arranged on the upper surface of the bottom side of the sampling support 1, and the movable base 18 is slidably matched with the sampling support 1; an electric push rod 19 arranged on the inner wall of the sampling support 1, and the telescopic end of the electric push rod 19 is connected to the side wall of the movable base 18.

[0039] In this embodiment, when the position of the sampling mechanism needs to be adjusted, it is only necessary to start the electric push rod 19, and its telescopic end will push the movable base 18, so that the movable base 18 slides along the sampling support 1 to the desired position. This design not only improves the convenience of the sampling operation, but also enhances the applicability and flexibility of the sampling mechanism.

[0040] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the sampling mechanism also includes: a sampling disk 20 arranged on the mobile base 18, and the sampling disk 20 is rotatably matched with the mobile base 18; a servo motor 21 arranged in the mobile base 18, and the output end of the servo motor 21 is fixedly connected with the end key of the sampling disk 20.

[0041] In this embodiment, the servo motor 21 drives the sampling disk 20 to rotate until the sampling tube 23 on the sampling disk 20 is aligned with the nozzle of the branch material pipe 14. At this time, a stable water vapor flow will pass through the main material pipe 13 and be adjusted by the balance flow valve 12 to ensure the stability of the flow. Then, the water vapor will pass through the branch material pipe 14 and be monitored by the flow meter 15 to complete the sampling work.

[0042] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a plurality of mounting grooves 22 are formed on the upper surface of the sampling plate 20 , and sampling tubes 23 are disposed in the mounting grooves 22 .

[0043] In this embodiment, the sampling disk 20 rotates to align the next sampling tube 23 with the sampling position, and then the above sampling steps are repeated. In this way, multi-point sampling of water vapor can be achieved, so as to have a more comprehensive understanding of the quality and characteristics of the water vapor.

[0044] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the sampling support 1 is provided with a guide groove 24 for the movable base 18 to slide.

[0045] In this embodiment, due to the limiting effect of the guide slot 24, the movable base 18 can only slide along a specific path, thereby ensuring the stability and accuracy of the sampling mechanism.

[0046] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a temperature sensor 25 is provided on the side wall of the raw material pipeline 2 , and a buzzer alarm 26 is provided on the sampling support 1 .

[0047] In this embodiment, the temperature sensor 25 on the side wall of the raw material pipeline 2 and the buzzer alarm 26 on the sampling support 1 together constitute the monitoring and alarm mechanism of the water vapor sampling and stabilizing flow device. This mechanism can monitor the temperature change of water vapor in real time and issue an alarm in time when an abnormality occurs, reminding the operator to pay attention and take corresponding measures to deal with it, thereby ensuring the safe and stable operation of the device.

[0048] The present invention also provides a low-temperature water vapor sampling and stabilizing flow system, including an operation panel 27, which is arranged beside the sampling support 1, and is electrically connected to the temperature sensor 25, the buzzer alarm 26, the sampling mechanism and the cooling mechanism.

[0049] In this embodiment, if the system fails during operation, such as a failure of the temperature sensor 25 (PT100) or a jam of the sampling mechanism, the operation panel 27 will display the fault information and trigger the buzzer alarm 26 (AD16-22SM) to sound an alarm. The operator can take timely measures to handle the fault according to the fault information and the alarm to ensure the normal operation of the system.

[0050] Working principle: The raw material pipeline 2 of the device is located inside the sampling support 1, and is responsible for transmitting the water vapor to be sampled; the source of the water vapor is connected to the first pump body 4 through the feeding pipeline 3, and the first pump body 4 plays a pumping role, sending the water vapor from the source into the raw material pipeline 2; as the water vapor flows in the raw material pipeline 2, it will be guided to the lower part of the device;

[0051] In order to ensure that the temperature of the water vapor is stable and moderate before sampling, the device is equipped with a cooling mechanism outside the raw material pipeline 2; the core component of the cooling mechanism is the cooling bin 6 surrounding the outer wall of the raw material pipeline 2, which is connected to the two water tanks 7 through the water pipe 8 to form a circulating water circuit; the second pump body 9 pushes the cooling water to circulate between the cooling bin 6 and the water tank 7 on the water pipe 8; when the cooling water flows through the cooling bin 6, it absorbs the heat of the water vapor in the raw material pipeline 2 to achieve a cooling effect; in order to improve the cooling efficiency, the upper part of the two water tanks 7 away from the cooling bin 6 is provided with a mounting groove 22, and a cooling fan 10 is installed; the cooling fan 10 accelerates the flow of air around the water tank 7, helping to dissipate heat to the environment faster; at the same time, the side wall of the water tank 7 adjacent to the cooling fan 10 is provided with a heat conducting sheet 11, which increases the heat exchange area and further improves the heat dissipation efficiency;

[0052] The water vapor continues to flow in the raw material pipeline 2 and eventually reaches the lower part of the feed pipeline 5, where a balanced flow stabilizing valve 12 is installed; the balanced flow stabilizing valve 12 provides a constant resistance to the flow of water vapor, ensuring that the water vapor flow passing through it is stable; no matter how the water vapor flow in the raw material pipeline 2 fluctuates, the balanced flow stabilizing valve 12 can ensure that the water vapor flow received by the sampling mechanism is constant; the stable water vapor flow regulated by the balanced flow stabilizing valve 12 enters the main feed pipe 13; to ensure the one-way flow of water vapor, a main one-way valve 16 is installed on the main feed pipe 13, which only allows water vapor to flow from the balanced flow stabilizing valve 12 to the downstream of the main feed pipe 13;

[0053] Next to the main material pipe 13, a branch material pipe 14 is provided for water vapor sampling; the branch material pipe 14 is equipped with a flow meter 15 to capture and record the water vapor flow data in real time; at the same time, a branch check valve 17 is also installed on the branch material pipe 14 to ensure the one-way flow of water vapor, allowing only water vapor to flow from the main material pipe 13 into the branch material pipe 14 and pass through the flow meter 15 to complete sampling, thereby effectively preventing the sampling operation from having adverse effects on the entire system;

[0054] When the position of the sampling mechanism needs to be adjusted, the telescopic end of the electric push rod 19 pushes the movable base 18 to slide along the sampling support 1 to the required position; this design improves the convenience of the sampling operation and the applicability and flexibility of the sampling mechanism; the servo motor 21 drives the sampling plate 20 to rotate, so that the sampling tube 23 is aligned with the nozzle of the branch material pipe 14; at this time, the stable water vapor flow passes through the main material pipe 13 and the balance flow valve 12 to ensure that the flow is stable, and then enters the branch material pipe 14, and the flow is monitored by the flow meter 15 to complete the sampling work; the sampling plate 20 continues to rotate, so that the next sampling tube 23 is aligned with the sampling position, and then the above sampling steps are repeated to achieve multi-point sampling and fully understand the quality and characteristics of water vapor;

[0055] The temperature sensor 25 on the side wall of the raw material pipeline 2 and the buzzer alarm 26 on the sampling support 1 together form a monitoring and alarm mechanism; this mechanism monitors the temperature changes of water vapor in real time, and promptly issues an alarm when an abnormality occurs, reminding the operator to pay attention and take measures to ensure the safe and stable operation of the device; if the system fails during operation, such as failure of the temperature sensor 25, jamming of the sampling mechanism, etc., the operation panel 27 will display the fault information and trigger the buzzer alarm 26 to sound an alarm; the operator takes timely measures to handle the fault according to the fault information and the alarm to ensure the normal operation of the system.
