Description

Technical Field

[0001] The utility model relates to the technical field of detection instrument auxiliary systems, in particular to a pH meter measurement buffer system applicable to slurry fluids. Background Art

[0002] PH meters are widely used in thermal power, chemical, food, pharmaceutical and water plants, and the size of PH value is crucial to the production process. Most PH meters are used in relatively simple slurry media such as circulating water and wastewater, but when used in complex fluids such as pressurized grouting, even if the appropriate model of PH meter is selected according to the actual situation on site, the characteristics of the medium, the environment, temperature and other factors, the electrode is always easy to wear after installation, which affects the life.

[0003] The common installation methods of pH meter are immersion type, pipeline type and flow type. For the flow type installation method, the pH meter electrode needs to be equipped with a flow cell. For general pressurized fluids, the flow type installation method can be selected, which can better protect the pH meter electrode and extend its life.

[0004] The pH meter electrode itself is difficult to maintain, requiring regular cleaning and calibration, and its installation requirements are also more complicated. In addition, the flow cell provided by the manufacturer of the flow-through installation method is often small, and the buffering effect is insufficient for complex fluids such as grouting liquid, and the probe is still easily worn. Utility Model Content

[0005] The utility model aims to provide a pH meter measurement buffer system applicable to slurry fluids, which can solve the problems of troublesome maintenance of pH meter electrodes and easy abrasion of the probe part by the pressurized slurry.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A pH meter measurement buffer system applicable to slurry fluids comprises a buffer tank and a pH meter mounted on the top of the buffer tank. A liquid inlet pipe, a liquid outlet pipe and a flushing pipe are arranged on the side wall of the buffer tank. The height of the liquid inlet pipe is lower than the height of the liquid outlet pipe. The lowest point height of the pH meter is lower than the highest point height of the liquid outlet pipe. A sewage pipe is arranged at the bottom of the buffer tank. The caliber of the buffer tank is DN350 to DN450, and the height of the buffer tank is 500 mm.

[0008] Preferably, the diameter of the sewage pipe is DN50.

[0009] Preferably, the diameter of the liquid outlet pipe is smaller than the diameter of the liquid inlet pipe.

[0010] Preferably, the caliber of the liquid outlet pipe is DN15 to DN25; the caliber of the liquid inlet pipe is DN25 to DN40.

[0011] Preferably, manual ball valves are provided before the liquid inlet pipe, liquid outlet pipe, flushing pipe and sewage pipe to control and adjust the slurry flow rate.

[0012] Preferably, the height of the highest point of the liquid inlet pipe is lower than the height of the lowest point of the pH meter.

[0013] Preferably, the flushing pipeline extends to the interior of the buffer tank and is close to the pH meter.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. The diameter of the buffer tank is DN350 to DN450, which reduces the flow rate and has a good buffering effect.

[0016] 2. Add a flushing pipe to flush the electrode probe of the pH meter for easy maintenance.

[0017] 3. Add sewage pipes to prevent slurry sedimentation and blockage of circulation or drain the solution when necessary. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0022] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand the advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0023] Embodiment 1

[0024] The utility model cleans the pH meter by setting a flushing pipe, which does not need to be disassembled from the buffer tank body, making it easy to maintain. At the same time, the caliber of the buffer tank body is DN350 to DN450, which reduces the flow rate, plays a good buffering effect and cooperates with the liquid outlet pipe and the sewage pipe to avoid damage to the pH meter due to the impact of excessive slurry pressure in the buffer tank body. It can be used to monitor the pH value of the desulfurization solution in the desulfurization system and monitor the desulfurization efficiency at any time. Or some other slurry fluids, it can also be used in vibrating pipes. Since the measurement system is relatively independent, the influence of the vibration of the main pipe on the pH meter can be ignored, and the system can also measure the pH value of the vibrating pipe.

[0025] A pH meter measurement buffer system applicable to slurry fluids comprises a buffer tank 1 and a pH meter 2 installed on the top of the buffer tank. A liquid inlet pipe 3, a liquid outlet pipe 4 and a flushing pipe 5 are arranged on the side wall of the buffer tank 1. The height of the liquid inlet pipe 3 is lower than the height of the liquid outlet pipe 4. The lowest point of the pH meter 2 is lower than the highest point of the liquid outlet pipe 4, so as to ensure that the electrode probe of the pH meter 2 can definitely contact the fluid. The electrode of the pH meter 2 needs to be equipped with a protective cover when purchasing or the protective cover is made on site.

[0026] A sewage pipe 6 is provided at the bottom of the buffer tank 1. The caliber of the buffer tank 1 is DN350 to DN450, and the height of the buffer tank 1 is 500 mm. The specific caliber of the buffer tank 1 can be determined according to the viscosity of the medium, etc., to solve the problem that the flow rate of the pressurized fluid containing more solid particles is too high to cause wear on the probe and the inlet and outlet pipes are easy to be blocked.

[0027] Furthermore, the diameter of the sewage pipe 6 is DN50. The sewage pipe 6 can avoid the situation that the flowability is poor and the measurement results are affected by the blockage caused by the deposition of some solid particles during long-term operation.

[0028] Further, the caliber of the liquid outlet pipe 4 is smaller than the caliber of the liquid inlet pipe 3. Further, the caliber of the liquid outlet pipe 4 is DN15 to DN25; the caliber of the liquid inlet pipe 3 is DN25 to DN40. Ensure that the slurry flow rate entering the buffer tank body 1 is greater than the slurry flow rate discharged from the buffer tank body 1, and ensure that the probe can contact the measured solution.

[0029] Furthermore, manual ball valves 7 are provided before the liquid inlet pipe 3, the liquid outlet pipe 4, the flushing pipe 5 and the sewage pipe 6 to control and adjust the slurry flow rate.

[0030] Furthermore, the highest point of the liquid inlet pipe 3 is lower than the lowest point of the pH meter 2 to avoid the grouting liquid directly impacting the pH meter 2, thereby damaging the electrode probe of the pH meter 2.

[0031] Furthermore, the flushing pipeline 5 extends to the interior of the buffer tank 1 and is close to the pH meter 2, so that the electrode probe of the pH meter 2 can be flushed.

[0032] Working principle:

[0033] When installing this system, the liquid can be directly welded to the liquid inlet pipe 3 after being connected from the main pipe to be tested, the liquid outlet pipe 4 can be connected to the underground tank or other storage tanks or directly connected back to the tower, the flushing pipe 5 is connected from the desalted water main pipe, and the sewage pipe 6 is connected to the drainage pipe of the process system, and the direction can be adjusted according to the actual process flow. The flow of each pipeline can be controlled and adjusted by the manual ball valve 7. After all the pipelines are installed, the pH meter 2 is finally installed. The pH meter 2 is installed on the top of the buffer tank 1, and the opening is matched and installed according to the selection of different manufacturers.

[0034] After the device is operating normally, it is only necessary to open the manual ball valve 7 of the liquid inlet pipe 3 and the liquid outlet pipe 4. After the pH meter 2 has been used for a period of time, open the manual ball valve 7 of the flushing pipe 5 and the sewage pipe 6 to flush the buffer tank 1 and the pH meter 2. The frequency of flushing is determined according to the usage and whether the slurry of the measured solution contains substances with high viscosity. Generally, it can be opened regularly for about one or two months.
