Description

Technical Field

[0001] This invention relates to the field of thermal power generation technology, and in particular to a method and dosing device for stabilizing the pH value of high-purity water. Background Technology

[0002] The water in the steam system of thermal power generating units has a very high purity. In order to prevent the steam system from corroding steel and copper, it is generally required to control the pH value of the water within a strict range. Otherwise, corrosion will occur. The premise of strictly controlling the pH value is to accurately measure the pH value of the water sample.

[0003] In actual operation, liquid junction potential and static charge have a significant impact on pH electrodes, resulting in large fluctuations in pH measurement and causing detection errors. Consequently, the detection information is inaccurate, making it impossible for staff to effectively judge and control the pH value of water. To solve this problem, we propose a method and dosing device for stabilizing the pH measurement value of high-purity water. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the fact that the liquid junction potential and static charge have a significant impact on the pH electrode during actual operation, resulting in large fluctuations in pH measurement, thus causing detection errors and inaccurate detection information, and making it impossible for staff to effectively judge and control the pH value of water quality, this invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a method for stabilizing the pH measurement value of high-purity water.

However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0040] Example 1

[0041] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a method for stabilizing the pH measurement value of high-purity water. The method includes:

[0042] S1. Install a dosing device outside the online pH meter measurement loop of the steam monitoring system in thermal power generating units;

[0043] The dosing device is fixed outside the pH meter measurement circuit of the water vapor monitoring system, which facilitates intuitive observation of the actual situation and allows for convenient addition of chemicals nearby.

[0044] S2. By installing a reagent bottle on the dosing device;

[0045] The reagent bottle contains a reagent used to neutralize and stabilize the pH value of high-purity water. By delivering this reagent, the reagent mixes with the water, achieving the goal of pH stability.

[0046] S3. A delivery pipe is connected to the bottom of the reagent bottle, and a dosing pump is installed on the delivery pipe;

[0047] The dosing pump can draw reagents from reagent bottles through delivery pipelines and then deliver the reagents from the reagent bottles to designated locations.

[0048] S4. A dosing pump is connected to a reagent bottle via a delivery pipe, and the reagent in the reagent bottle is drawn out through the delivery pipe. The delivery pipe extends from the other end of the dosing pump to the pH electrode flow cell. The reagent drawn out by the dosing pump then flows into the pH electrode flow cell through the delivery pipe, thereby achieving the dosing to stabilize the pH measurement value of the high-purity water.

[0049] S5. By adding a trace amount of neutral adjusting agent to the sample water, the agent reacts with the sample water, enhancing the ionic strength and conductivity of the sample water without changing the pH value, shielding the flow potential in the measuring cell, thereby avoiding the influence of static charge and promoting the stability of liquid junction potential, thus effectively ensuring the accuracy of water quality pH measurement.

[0050] Example 2

[0051] Reference Figures 1-4 The second embodiment of the present invention provides a dosing device for stabilizing the pH measurement value of high-purity water. This device includes a clamping mechanism 100, including a horizontally arranged fixing component 101, two sets of clamping components 102 symmetrically arranged on one side of the fixing component 101, and a clamping spring 103 disposed between the fixing component 101 and the clamping components 102.

[0052] During use, the inner side of the clamping component 102 has an arc-shaped structure, which can better fit the arc-shaped surface of the reagent bottle. At the same time, the clamping component 102 is slidably set on one side of the fixing component 101. With the elastic support of the clamping spring 103 installed between the two, the clamping components 102 are clamped together inward. With the elastic extension and contraction support of the clamping spring 103, the distance between the clamping components 102 can be adjusted according to the size of the reagent bottle while clamping and fixing the reagent bottle.

[0053] The clamping mechanism 200 includes an adjustment component 201 disposed above the fixing component 101, a transmission component 203 disposed on both sides of the adjustment component 201 and located above the clamping component 102, a transmission belt 202 disposed between the adjustment component 201 and the transmission component 203, an extension component 204 disposed on the transmission component 203, two sets of clamping components 205 disposed on the extension component 204, and an external component 206 disposed at the top of the extension component 204.

[0054] During use, the transmission belt 202 is sleeved on the ends of the transmission components 203 on both sides, and the middle position is pressed and fitted by the adjustment component 201. The extension component 204 is threadedly connected inside the transmission component 203, the external component 206 is fixedly connected to the top of the extension component 204, and the clamping component 205 is sleeved on the extension component 204. The adjustment component 201 rotates and drives the transmission component 203 to rotate through the transmission belt 202. The rotating transmission component 203 will extend the extension component 204 outward, thereby pushing the external component 206 and the clamping component 205 outward, thereby increasing the clamping range. The clamping component 205 and the external component 206 can increase the contact points with the reagent bottle, thereby increasing the clamping stability.

[0055] The dosing mechanism 300 includes a fixing plate 301 disposed below the fixing component 101, a dosing pump 302 disposed on the fixing plate 301, an inlet pipe 303 disposed above the dosing pump 302, and a buffer pipe 304 disposed below the dosing pump 302.

[0056] During use, the fixing plate 301 is used to fix the whole device. The liquid inlet pipe 303 is connected between the dosing pump 302 and the reagent bottle. It is used by the dosing pump 302 to draw the reagent in the reagent bottle. The buffer pipe 304 is relatively long. The reagent flowing in it will have a long contact time with the water flow, thereby achieving complete dissolution and uniform mixing. The dosing pump 302 can draw the reagent in the reagent bottle and deliver it to the designated location.

[0057] Example 3

[0058] Reference Figures 3-9 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that it can clamp and fix reagent bottles of different sizes, which facilitates the normal operation of drug dosing and meets more usage needs.

[0059] Compared to Embodiment 2, the fixing component 101 further includes a rectangular fixing block 101a, a mounting bracket 101b disposed at the center of the fixing block 101a, a support component 101c disposed on the fixing block 101a and located on both sides of the mounting bracket 101b, and a limiting block 101d disposed at both ends of the fixing block 101a. The support component 101c includes a support air rod 101c-1 and an auxiliary wheel 101c-2. The transmission belt 202 is sleeved on the auxiliary wheel 101c-2 and is lifted by the clamping component 102.

[0060] The clamping component 102 includes a mounting assembly 102a located on one side of the fixing block 101a, a limiting sleeve 102b disposed above the mounting assembly 102a, a first limiting piece 102c disposed on the mounting assembly 102a and close to the fixing block 101a, two sets of limiting frames 102d disposed on the other side of the mounting assembly 102a, and multiple sets of clamping components 102e disposed inside the mounting assembly 102a. The first limiting piece 102c includes 102c-1 and 102c-2 disposed at the top of 102c-1. The clamping spring 103 is sleeved on 102c-1 and located between the limiting blocks 101d and 102c-2. 102c-1 has a hexagonal prism structure, which can prevent the clamping component 102 from rotating unnecessarily.

[0061] During use, the clamping component 102 presses the clamping spring 103 to both sides, causing the clamping component 102 to expand to both sides of the fixing component 101 through the first limiting piece 102c, thereby achieving the purpose of changing according to the size of the reagent bottle. At the same time, the clamping assembly 102e is rotatably connected to the inside of the mounting assembly 102a, and can change accordingly according to the curvature of the outer wall of the reagent bottle, so as to better fit the outer wall of the reagent bottle. During this process, the clamping spring 103 will continuously apply elastic support force inward, pushing the clamping component 102 to clamp and fix the reagent bottle, ensuring the fixation effect.

[0062] The adjustment component 201 includes an adjustment knob 201a disposed on the mounting frame 101b and a pressure roller 201b disposed on one side of the adjustment knob 201a. The adjustment knob 201a is sleeved on the mounting frame 101b, and the pressure roller 201b is fixedly connected to the adjustment component 201.

[0063] The transmission component 203 includes a sleeve rod 203a disposed on the limiting sleeve 102b, a limiting wheel 203b disposed at one end of the sleeve rod 203a, and a first limiting ring 203c disposed on the sleeve rod 203a and located on both sides of the limiting sleeve 102b. The sleeve rod 203a is limited and fixed on the limiting sleeve 102b by the first limiting ring 203c, and the outermost end of the transmission belt 202 is sleeved on the limiting wheel 203b.

[0064] During use, when the adjusting component 201 rotates, it drives the transmission component 203 to rotate via the transmission belt 202. The transmission component 203, limited by the first limiting ring 203c, can only rotate in its original position on the clamping component 102. The two ends of the transmission belt 202 are sleeved on the limiting wheel 203b, and the center position is pressed by the adjusting component 201. At the same time, the support components 101c on both sides of the adjusting component 201 will lift the transmission belt 202, making the transmission belt 202 taut. When the clamping component 102 moves to both sides, the clamping component 102 will pull the transmission belt 202 to extend via the transmission component 203. The transmission belt 202 will compress the support component 101c to contract, thereby achieving the purpose of extending the lateral range.

[0065] The extension component 204 includes a threaded rod 204a located inside the sleeve rod 203a, a support rod 204b disposed at one end of the threaded rod 204a, a first push plate 204c disposed between the threaded rod 204a and the support rod 204b, and a second push plate 204d disposed on the support rod 204b. The threaded rod 204a is threadedly connected inside the sleeve rod 203a, the support rod 204b has a hexagonal rectangular structure, and the diameter of the first push plate 204c is larger than the diameter of the second push plate 204d.

[0066] The clamping assembly 205 includes a first mounting block 205a located on the clamping assembly 102e, a first fixing ear 205b disposed above the first mounting block 205a, and a contact assembly 205c disposed on one side of the first mounting block 205a. The first mounting block 205a has a first limiting groove 205a-1 and a storage groove 205a-2 inside the first mounting block 205a. The first fixing ear 205b has a limiting hole 205b-1. The size of the limiting hole 205b-1 is larger than that of the second push plate 204d and smaller than that of the first push plate 204c.

[0067] During use, the contact component 205c includes a push rod 205c-1 slidably disposed on the side of the first mounting block 205a. The push rod 205c-1 extends into the storage groove 205a-2 and has a second limiting piece 205c-3 at its end for limiting. A rotating shaft 205c-2 is disposed at the top of the push rod 205c-1, and a top plate 205c-4 is rotatably connected to the rotating shaft 205c-2. The rotatably connected top plate 205c-4 can change accordingly with the curvature of the outer wall of the reagent bottle, better fitting the outer wall of the reagent bottle. At the same time, a support spring 205c-5 is disposed in the storage groove 205a-2. The support spring 205c-5 pushes the rotating shaft 205c-2 outward and can retract accordingly according to the pressure received, thereby better clamping and fitting the curved outer wall of the reagent bottle.

[0068] There are two sets of clamping components 205 on the support rod 204b. They have basically the same structure. The difference is that the clamping component 205 near the outer component 206 does not have a limiting hole 205b-1. Instead, it has a slot that matches the support rod 204b.

[0069] The external component 206 includes a second mounting block 206a disposed at the top of the support rod 204b, a second fixing ear 206b disposed above the second mounting block 206a, and a roller 206c disposed on one side of the second mounting block 206a. The second mounting block 206a is fixedly connected to the top of the support rod 204b through the second fixing ear 206b, and the structure of the second mounting block 206a is bent inward, which can serve to hug and fit the outer wall of the reagent bottle. The roller 206c is rotatably connected to the outside of the second mounting block 206a.

[0070] The clamping assembly 205 and the external assembly 206 are slidably connected to the clamping assembly 102e from the inside to the outside. The support rod 204b passes through the clamping assembly 205 from above and is fixedly connected to the external assembly 206. The clamping assembly 205 and the external assembly 206 can only slide on the clamping assembly 102e and cannot slide together because of the limiting of the clamping assembly 102e. At the same time, the support rod 204b cooperates with the limiting of the clamping assembly 102e through its special hexagonal prism structure, so that the extension part 204 rotates under the drive of the transmission part 203.

[0071] During use, the rotating sleeve 203a, through its threaded connection with the threaded rod 204a, pushes the threaded rod 204a to extend outward. The extended extension component 204 then pushes the clamping assembly 205 and the external assembly 206 outward, thereby increasing the lateral clamping range of the device and achieving the purpose of clamping reagent bottles of different sizes. Depending on the usage requirements, as the support rod 204b continues to move, the first push plate 204c and the second push plate 204d of different sizes on the support rod 204b will sequentially push the outermost clamping assembly 205 and the innermost clamping assembly 205 to move in sequence. The sequentially moving clamping assembly 205 will contact the outer wall of the reagent bottle at different positions. In addition, the cooperation with the external assembly 206 increases the contact points with the reagent bottle, thereby increasing the stability of the clamping and fixing.

[0072] The remaining structure is the same as that in Example 2.
