[0001] The utility model belongs to the technical field of desulfurization measuring devices, and specifically relates to a desulfurization pH open measuring pool. Background Art

[0002] As environmental regulations become increasingly stringent, industrial emission standards are also constantly increasing. In many industrial processes, especially coal-fired power plants, steel manufacturing, and the chemical industry, flue gas desulfurization is one of the key steps to reduce air pollutant emissions. Flue gas desulfurization refers to the process of removing sulfur dioxide (SO2) from industrial flue gases to reduce acid rain and air pollution. Effective desulfurization technology is essential to protect the environment and human health.

[0003] Among them, in the wet flue gas desulfurization system, pH value is a key parameter, which directly affects the solubility and reaction rate of the desulfurizer, thereby affecting the desulfurization efficiency of the entire system. At present, when measuring the desulfurization pH value, the pH sensor is directly inserted into the desulfurization slurry. Due to the inadequate reaction of the slurry, the pH value measurement is inaccurate. Utility Model Content

[0004] The purpose of the utility model is to provide a desulfurization pH open measurement pool, which can reduce the concentration of solid particles and dissolved substances in the slurry by accommodating the slurry in the reaction pool and completing the reaction with the flushing water in the reaction component, thereby reducing the pH measurement error. The pH electrode arranged in the reaction pool helps to improve the accuracy and stability of the measurement, and can more accurately measure the pH value of the desulfurization slurry, thereby improving efficiency.

[0014] Furthermore, the pH electrodes are respectively a glass electrode and a reference electrode.

[0015] The technical effects achieved by the utility model are:

[0016] The utility model provides a desulfurization pH open measurement pool, which completes dilution by reacting the reaction containing slurry with the reaction water in the reaction component, so that the slurry is closer to the ideal solution state, which can reduce the measurement error caused by the slurry characteristics and make it reach the equilibrium state faster, thus facilitating measurement. It can also change the viscosity and density of the slurry, create more favorable conditions for the measurement of pH value, obtain more stable results, and improve the reliability of data.

[0023] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of the utility model, and does not strictly limit the scope of protection of the specific request of the utility model.

[0024] like Figure 1-Figure 3 As shown, a desulfurization pH open measurement tank includes a reaction tank 10, and a slurry inlet 11 and a discharge port 12 are fixedly opened on the reaction tank 10;

[0025] The reaction assembly 20 includes a flushing water pipe 21 fixedly arranged in the reaction tank 10, a flushing port 22 is opened on the flushing water pipe 21, and one end of the flushing water pipe 21 extending to the outside of the reaction tank 10 is fixedly connected to a flushing water electric door 23;

[0026] The measuring component 30 comprises a mounting bracket 31 slidably arranged above the reaction pool 10 . The mounting bracket 31 is provided with a mounting hole 311 . A pH electrode 32 is fixedly arranged in the mounting hole 311 .

[0027] It should be noted that a one-way valve (not shown) is provided on the flushing port 22 to prevent the slurry from flowing back into the flushing water pipe 21. The mounting bracket 31 is slidably connected to the reaction tank 10 and can rotate above the reaction tank 10 to drive the pH electrode 32 to rotate, so that the slurry at different angles in the reaction tank 10 can be measured.

[0028] In this embodiment, the reaction tank 10 is used to accommodate the slurry and the flushing water to react, so as to facilitate the measurement of the pH value. A slurry inlet 11 and a discharge port 12 are provided on the reaction tank 10. Among them, the slurry inlet 11 is used to introduce the slurry to be measured, and the discharge port 12 is used to discharge the measured slurry. The reaction component 20 is used to provide flushing water to react with the slurry, which can reduce the concentration of solid particles and dissolved substances in the slurry, thereby reducing the pH measurement error. Among them, the reaction component 20 includes a flushing water pipe 21, which is used to transmit flushing water to react with the slurry in the reaction tank 10. By providing a flushing port 22 on the flushing water pipe 21, the flushing water can be evenly distributed in the reaction tank 10. Specifically, one end of the flushing water pipe 21 extending to the outside of the reaction tank 10 is connected to the flushing water electric door 23, which can control the flow of flushing water. The measuring component 30 is used to measure the slurry in the reaction tank 10 to ensure the monitoring of the pH value during the desulfurization process to optimize the desulfurization effect and reduce environmental pollution. The measuring assembly 30 includes a mounting bracket 31 and a pH electrode 32. The mounting bracket 31 is slidably disposed above the reaction pool 10 and is used to support and fix the pH electrode 32. The position can be adjusted as needed. A mounting hole 311 is provided on the mounting bracket 31 to fix the pH electrode 32 and ensure its stability during use.

[0029] like Figure 2 As shown, by arranging the slurry inlet 11 at the bottom of the reaction tank 10, the slurry can be effectively transmitted. The slurry transmission pipe 111 is fixedly connected in the slurry inlet 11, which helps to transmit the slurry so that it is evenly distributed in the reaction tank 10, ensuring the full progress of the reaction. It should be noted that the flushing water pipe 21 is sleeved on the outside of the slurry transmission pipe 111, so that the flushing water can directly contact the slurry entering the reaction tank 10, thereby achieving rapid and uniform mixing. Among them, by arranging the discharge port 12 on the side wall of the reaction tank 10, it can be ensured that the slurry after the full reaction is discharged. By fixing the slurry discharge pipe 121 at the discharge port 12, the treated slurry can be discharged smoothly, ensuring the cleanliness of the internal environment of the reaction tank 10, and providing good initial conditions for the next round of desulfurization reaction. By setting the slurry transmission pipe 111 and the slurry discharge pipe 121, the desulfurization efficiency can be effectively improved.

[0030] Preferably, there are multiple flushing ports 22. By arranging the flushing ports 22 at the central array position of the reaction tank 10, it can be effectively ensured that the flushing water can evenly cover the entire surface of the reaction tank 10, thereby improving the accuracy and stability of the reaction. The flushing ports 22 are opened above the flushing water pipe 21 to ensure smooth flushing and improve the quality and efficiency of the device measurement.

[0031] like Figure 3As shown, there are two mounting holes 311, which are placed on the mounting bracket 31 and symmetrically distributed along the central axis of the mounting bracket 31. By arranging the pH electrode 32 in the mounting hole 311, it is possible to ensure that the pH electrode 32 is evenly arranged and provide accurate measurement results. Among them, the pH electrodes 32 are glass electrodes and reference electrodes. The glass electrode is used as an indicator electrode in conjunction with the reference electrode to accurately determine the pH value of the solution by measuring the electromotive force of the battery. The glass electrode is used to measure the hydrogen ion concentration in the slurry and can provide an accurate pH value. The reference electrode is used to provide a stable reference potential to ensure the accuracy and stability of the measurement.

[0032] The working principle of the utility model is as follows: when desulfurization pH measurement is required, the slurry is transferred to the reaction tank 10 through the slurry transfer pipe 111 provided at the bottom of the reaction tank 10, wherein the delivery of flushing water in the flushing water pipe 21 is controlled by the opening and closing of the flushing water electric door 23, and the flushing water is transferred to the reaction tank 10 through the flushing port 22 provided on the flushing water pipe 21 to mix with the slurry. The pH electrode 32 is fixedly supported by the mounting bracket 31 provided above the reaction tank 10, so that the pH electrode 32 measures the slurry in the reaction tank 10. The measured slurry can be discharged through the slurry discharge pipe 121 through the discharge port 12 provided on the reaction tank 10.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be regarded as the protection scope of this utility model. The structures, devices and operating methods not specifically described and explained in this utility model shall be implemented according to the conventional means in this field unless otherwise specified and limited.
