Description

Technical Field

[0001] This utility model relates to the field of sample collection technology, specifically to a sample tube dewatering device that is easy to adjust. Background Technology

[0002] In fields such as environmental monitoring and industrial process analysis, it is necessary to collect gas samples from gas pipelines through sampling tubes for component analysis. However, water vapor in the gas samples can severely interfere with the test results and may also react with acidic components in the samples (such as SO2 and NO). x The reaction produces corrosive substances, shortening the lifespan of the sampling tube and the testing instrument. Therefore, efficient dehydration treatment of the gas collected by the sampling tube is a key pretreatment step to ensure the accuracy of the test data.

[0003] In the existing technology, most existing water removal devices adopt a fixed channel design. When sampling is required, one end of the device usually needs to be connected to the gas pipeline and the other end to the sampling tube. After sampling, it also needs to be removed from the gas pipeline, which is cumbersome and prone to gas leakage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an easily adjustable sampling tube dehydration device, which solves the problems of cumbersome operation and easy gas leakage in existing dehydration devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable sampling tube dewatering device, comprising a housing, flanges fixedly connected to both sides of the housing, a rotating cylinder rotatably connected to the top of the housing, an internal threaded sleeve fixedly connected to the inner side of the rotating cylinder, a threaded rod threadedly connected to the inner side of the internal threaded sleeve, a flow guide block fixedly connected to the bottom of the threaded rod, and a guide rod fixedly connected to the top of the flow guide block. It also includes a filter assembly threadedly connected to the bottom of the housing. Rotating the rotating cylinder at the top of the housing causes the internal threaded sleeve to drive the threaded rod to move vertically. The guide rod prevents the flow guide block from rotating with the threaded rod. Ultimately, the threaded rod drives the flow guide block to slide upwards along the inner wall of the housing.

[0006] The filter assembly includes a connecting shell, with a condenser plate fixedly connected to the inner side of the connecting shell and a drain valve fixedly connected to the outer side of the connecting shell. The condenser plate condenses water vapor in the gas into liquid water through heat exchange. The liquid water flows downward along the surface of the condenser plate under the action of gravity and can eventually be discharged outside the device through the drain valve on the outer side of the connecting shell. A pull-out shell is slidably connected to the inner side of the connecting shell, and an activated carbon layer is placed inside the pull-out shell. The activated carbon layer adsorbs some of the remaining water vapor in the gas through its porous structure. A placement rack is fixedly connected to the bottom of the connecting shell, and a desiccant layer is placed inside the placement rack. The desiccant layer further removes residual water vapor in the gas through physical adsorption, ensuring that the gas entering the sampling tube is dry and free from moisture interference.

[0007] Preferably, the sidewall of the flow guide block is slidably connected to the inner wall of the housing, and the outer wall of the guide rod is slidably connected to the inner wall of the housing. The guide rod can prevent the flow guide block from rotating with the threaded rod.

[0008] Preferably, the wall of the guide block has a through hole, through which gas can flow along the fixed gas pipes on both sides of the housing. The wall of the guide block has a guide hole, which can change the flow direction and guide the gas entering the housing through the gas pipe directly into the connecting shell of the filter assembly.

[0009] Preferably, the top of the connecting shell is threaded to the bottom of the housing, a design that facilitates the removal of the filter assembly from the bottom of the housing.

[0010] Preferably, the condenser plate is located directly above the pull-out shell, and the pull-out shell is located directly above the placement rack. The gas first contacts the condenser plate inside the connecting shell for water vapor filtration, and then flows downward through the activated carbon layer inside the pull-out shell and the desiccant layer inside the placement rack, entering the sampling tube.

[0011] The beneficial effects of this utility model are as follows:

[0012] (i) The dewatering device is equipped with a guide block. When sampling is required, the rotating cylinder at the top of the shell is rotated, and the guide block slides upward along the inner wall of the shell. At this time, the gas entering the shell from the gas pipe will change its flow direction through the guide hole and be directly guided into the connecting shell of the filter component, and finally enter the sampling tube to complete the sampling. When sampling is not required, the rotating cylinder can be rotated in the opposite direction to reset the guide block and allow the gas to flow directly through the through hole. Thus, sampling and adjustment can be completed without disassembling the device, which is convenient for use.

[0013] (II) This dehydration device employs a filtration assembly. When gas enters the filtration assembly, the condenser plate condenses the water vapor in the gas into liquid water through heat exchange. The liquid water flows downwards along the surface of the condenser plate under gravity and is eventually discharged outside the device through a drain valve on the outside of the connecting shell. Subsequently, the activated carbon layer adsorbs the remaining water vapor in the gas through its porous structure. The gas then enters the desiccant layer inside the placement rack. The desiccant layer further removes residual water vapor in the gas through physical adsorption, ensuring that the gas entering the sampling tube is dry and free from moisture interference. If the filter material needs to be replaced, the pull-out shell can be slid out from the inside of the connecting shell to replace the activated carbon layer, ensuring the subsequent dehydration effect of the device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Please refer to Figure 1-4This utility model provides a technical solution: an easily adjustable sampling tube dehydration device, including a housing 1, flanges 2 fixedly connected to both sides of the housing 1, a rotating cylinder 3 rotatably connected to the top of the housing 1, an internal threaded sleeve 4 fixedly connected to the inner side of the rotating cylinder 3, a threaded rod 5 threadedly connected to the inner side of the internal threaded sleeve 4, a guide block 6 fixedly connected to the bottom of the threaded rod 5, and a guide rod 9 fixedly connected to the top of the guide block 6. It also includes a filter assembly 10, threadedly connected to the bottom of the housing 1. The entire device is sealed to the gas pipeline to be sampled via the flanges 2 fixedly connected to both sides of the housing 1, ensuring that the gas can only flow through the through hole 7 in the guide block 6 to prevent leakage. Then, the external sampling tube is connected to the bottom of the connecting shell 101 in the filter assembly 10, allowing the dehydrated gas to directly enter the sampling tube to complete the subsequent sampling operation.

[0021] The sidewall of the guide block 6 is slidably connected to the inner wall of the housing 1, and the outer wall of the guide rod 9 is slidably connected to the inner wall of the housing 1. A through hole 7 and a guide hole 8 are provided in the wall of the guide block 6. When sampling is required, the rotating cylinder 3 at the top of the housing 1 is rotated. The thread groove in the inner threaded sleeve 4 of the rotating cylinder 3 is matched with the threaded rod 5. The rotation of the rotating cylinder 3 will drive the threaded rod 5 to move vertically through the inner threaded sleeve 4. The guide rod 9 can prevent the guide block 6 from rotating with the threaded rod 5. Finally, the threaded rod 5 will drive the guide block 6 to slide upward along the inner wall of the housing 1. When the guide block 6 moves upward to the preset position... When in position, the guide hole 8 in the wall of the guide block 6 will form a communication path with the internal channel of the housing 1 and the inlet of the filter assembly 10. At this time, the gas entering the housing 1 from the gas pipeline will change its flow direction through the guide hole 8 and be directly guided into the connecting shell 101 of the filter assembly 10, and finally enter the sampling tube to complete the sampling. Thus, the gas in the gas pipeline can be directly introduced into the sampling tube. When sampling is not required, the rotating drum 3 can be rotated in the opposite direction to reset the guide block 6, so that the gas can flow directly through the through hole 7. Thus, sampling adjustment can be completed without disassembling the device, which is convenient for use.

[0022] The filter assembly 10 includes a connecting shell 101, a condenser plate 102 fixedly connected to the inner side of the connecting shell 101, a drain valve 103 fixedly connected to the outer side of the connecting shell 101, a pull-out shell 104 slidably connected to the inner side of the connecting shell 101, an activated carbon layer 105 placed inside the pull-out shell 104, a placement rack 107 fixedly connected to the bottom of the connecting shell 101, a desiccant layer 106 placed inside the placement rack 107, a threaded connection between the top of the connecting shell 101 and the bottom of the housing 1, the condenser plate 102 being located directly above the pull-out shell 104, and the pull-out shell 104 being located directly above the placement rack 107. When gas enters the filter assembly 10, the gas first contacts the condenser plate 102 inside the connecting shell 101, and the condenser plate 102 facilitates heat exchange between the gas and the condenser plate 102. Water vapor in the gas condenses into liquid water, which flows downward along the surface of the condenser plate 102 under the action of gravity. It can eventually be discharged from the device through the drain valve 103 on the outside of the connecting shell 101. After condensation and dehydration, the gas continues to flow downward and enters the activated carbon layer 105 inside the pull-out shell 104. The activated carbon layer 105 adsorbs the remaining water vapor in the gas through its porous structure. The gas finally enters the desiccant layer 106 inside the placement rack 107. The desiccant layer 106 further removes the residual water vapor in the gas through physical adsorption, ensuring that the gas entering the sampling tube is dry and free from moisture interference. If the filter material needs to be replaced, the pull-out shell 104 can be slid out from the inside of the connecting shell 101 to replace the activated carbon layer 105, ensuring the subsequent water removal effect of the device.

[0023] Working principle: During use, the entire device is sealed to the gas pipeline to be sampled by the flanges 2 fixedly connected to both sides of the housing 1, ensuring that the gas can only flow through the through hole 7 in the guide block 6 to avoid leakage. Then, the external sampling tube is connected to the bottom of the connecting housing 101 in the filter assembly 10, so that the gas after water removal treatment can directly enter the sampling tube to complete the subsequent sampling operation.

[0024] When sampling is required, the rotating cylinder 3 at the top of the housing 1 is rotated. The threaded groove in the inner threaded sleeve 4 of the rotating cylinder 3 is adapted to the threaded rod 5. The rotation of the rotating cylinder 3 will drive the threaded rod 5 to move vertically through the inner threaded sleeve 4. The guide rod 9 can prevent the guide block 6 from rotating with the threaded rod 5. Finally, the threaded rod 5 will drive the guide block 6 to slide upward along the inner wall of the housing 1. When the guide block 6 moves upward to the preset position, the guide hole 8 opened in the wall of the guide block 6 will form a communication path with the internal channel of the housing 1 and the inlet of the filter assembly 10. At this time, the gas entering the housing 1 from the gas pipeline will change its flow direction through the guide hole 8 and be directly guided into the connecting shell 101 of the filter assembly 10, and finally enter the sampling tube to complete the sampling. Thus, the gas in the gas pipeline can be directly introduced into the sampling tube. When sampling is not required, the rotating cylinder 3 can be rotated in the opposite direction to reset the guide block 6 and allow the gas to flow directly through the through hole 7. Thus, sampling adjustment can be completed without disassembling the device, which is convenient for use.

[0025] When gas enters the filter assembly 10, it first contacts the condenser plate 102 inside the connecting housing 101. The condenser plate 102 condenses the water vapor in the gas into liquid water through heat exchange. Since the condenser plate 102 is installed at an angle and has a gas guide notch at its top, the liquid water flows downward along the surface of the condenser plate 102 under the action of gravity and eventually accumulates near the drain valve 103. It can then be discharged outside the device through the drain valve 103 on the outside of the connecting housing 101. The gas, after being condensed and dehydrated, is then discharged through the gas guide... The gas continues to flow downwards through the gap, entering the activated carbon layer 105 inside the pull-out shell 104. The activated carbon layer 105 adsorbs the remaining moisture in the gas through its porous structure. The gas eventually enters the desiccant layer 106 inside the placement rack 107. The desiccant layer 106 further removes the residual moisture in the gas through physical adsorption, ensuring that the gas entering the sampling tube is dry and free from moisture interference. If the filter material needs to be replaced, the pull-out shell 104 can be slid out from the inside of the connecting shell 101 to replace the activated carbon layer 105, ensuring the subsequent water removal effect of the device.
