Description

Technical Field

[0001] This utility model relates to the field of pipeline medium sampling, specifically a process pipeline analysis and sampling device. Background Technology

[0002] In chemical production, it is necessary to measure process parameters such as pH and conductivity of the medium in vertical process pipelines that are not fully filled with liquid. If the electrodes are directly inserted into the process pipeline for measurement, an analyzer is a common device used to test the conductivity of liquid media. It measures the conductivity by directly inserting the electrodes into the process pipeline.

[0003] However, when the process pipeline is not full, the presence of air bubbles in the pipeline leads to significant measurement deviations or even makes measurement impossible. Furthermore, the long-term operation of the production system makes it impossible to calibrate pH meters, conductivity meters, etc., at any time, increasing the difficulty of maintaining the analyzer. Therefore, a process pipeline analysis and sampling device is proposed to address the above problems. Utility Model Content

[0021] 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 scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5 As shown, a process pipeline analysis and sampling device includes a sampling tube 11, which penetrates the side wall of the process pipeline and is welded and fixed to the process pipeline; the sampling tube 11 has an opening 13, a plug 14 is fixedly connected to one end of the sampling tube 11 inside the process pipeline, and a sampling stop valve 12 is installed at the other end of the sampling tube 11; the length of the opening 13 is less than the diameter of the process pipeline.

[0024] In use, the sampling tube 11 penetrates the side wall of the process pipeline and is welded and sealed to the process pipeline. The liquid medium inside the process pipeline flows out through the opening 13 on the sampling tube 11. Then, the sampling shut-off valve 12 is used to control the end switch of the sampling tube 11, which facilitates sampling and reduces the possibility of inaccurate measurement data caused by the analyzer electrode 31 being installed on the pipeline.

[0025] Furthermore, such as Figure 1-5 As shown, the sampling shut-off valve 12 is fixedly connected to a connecting pipe 21 at one end away from the sampling tube 11. The bottom end of the connecting pipe 21 is fixedly connected to a sampling container 22. A drain pipe 23 is installed at the bottom of the sampling container 22, and a valve is installed on the drain pipe 23. An analyzer electrode 31 is installed at the bottom of the sampling container 22 and is inserted into the interior of the sampling container 22. An exhaust pipe 32 is fixedly connected to the top of the sampling container 22.

[0026] In use, a connecting pipe 21 is installed at the end of the sampling stop valve 12, and a sampling tank 22 is connected to the end of the connecting pipe 21. The sampling tank 22 is used to store the liquid medium, and the bottom drain pipe 23 is used to discharge the liquid medium. The valve is used to control the switch. Furthermore, the analyzer electrode 31 is installed inside the sample tube, and the liquid medium is stored inside the sampling tank 22. Therefore, the influence of air bubbles on the measurement results can be reduced. At the same time, the relatively isolated detection environment reduces the possibility of damage to the analyzer electrode 31 due to excessive flow rate or negative pressure in the pipeline.

[0027] Furthermore, such as Figure 1-5 As shown, a valve body 4 is installed at the top of the exhaust pipe 32. A sealing cavity is opened inside the valve body 4. A through hole 43 communicating with the exhaust pipe 32 is opened at the bottom of the sealing cavity. A spring 41 is installed inside the sealing cavity. A sealing ball 42 is provided at the bottom of the spring 41. The sealing ball 42 is located at the top of the through hole 43. The bottom of the sealing ball 42 is inserted into the through hole 43 and seals the through hole 43. A vertical pipe 5 is fixedly connected inside the sampling container 22. The vertical pipe 5 is connected to the connecting pipe 21. The bottom end of the vertical pipe 5 is located below the analyzer electrode 31. Multiple evenly distributed perforated plates 6 are fixedly connected to the inner wall of the sampling container 22. The vertical pipe 5 passes through the evenly distributed perforated plates 6 and is fixedly connected to them.

[0028] When in use, the exhaust pipe 32 is used to discharge the internal air, and the spring 41 is used to press down the sealing ball 42, which makes the exhaust pipe 32 discharge air in one direction only. When not in use, the sealing ball 42 can seal the exhaust pipe 32. The sampling tank 22 is equipped with a vertical pipe 5 and multiple evenly distributed perforated plates 6. The evenly distributed perforated plates 6 are used to distribute the medium evenly and slow down the liquid rolling when high-speed medium enters, which facilitates the defoaming.

[0029] Furthermore, such as Figure 1-5 As shown, a tube seat is fixedly connected to the sampling vessel 22, and the analyzer electrode 31 and the tube seat are detachably connected via a flange.

[0030] Working principle: During use, the sampling tube 11 penetrates the side wall of the process pipeline and is welded and sealed to the process pipeline. The liquid medium inside the process pipeline flows out through the opening 13 on the sampling tube 11. The sampling shut-off valve 12 controls the opening and closing of the end of the sampling tube 11, facilitating sampling and reducing the risk of inaccurate measurement data due to the analyzer electrode 31 being installed on the pipeline. During use, a connecting pipe 21 is installed at the end of the sampling shut-off valve 12, and the end of the connecting pipe 21 is connected to a sampling tank 22. The sampling tank 22 stores the liquid medium, and a bottom drain pipe 23 discharges the liquid medium. The valve controls the opening and closing. Furthermore, the analyzer electrode 31 is installed on the sample... Inside the sampling tank 22, the liquid medium is stored to reduce the impact of air bubbles on the measurement results. The relatively isolated testing environment also reduces the risk of damage to the analyzer electrodes 31 due to excessive flow rate or negative pressure within the pipeline. During use, the exhaust pipe 32 is used to expel internal air, and the spring 41 presses down on the sealing ball 42, ensuring that the exhaust pipe 32 can only expel air in one direction. When not in use, the sealing ball 42 seals the exhaust pipe 32. A vertical pipe 5 and multiple evenly distributed perforated plates 6 are installed inside the sampling tank 22. These perforated plates serve to distribute the liquid evenly, reducing liquid turbulence and facilitating bubble removal as high-speed media enters.
