Description
Technical Field
[0001] The utility model relates to the technical field of water vapor detection equipment and peripheral supporting facilities for solar thermal power generation and thermal power generation, and in particular to an integrated water vapor quality detection device suitable for power generation systems. Background Art
[0002] Solar thermal power generation is a process that uses heat exchangers to provide steam, combined with traditional steam turbine generators, to generate electricity. Solar thermal power generation is currently an important area of new energy utilization.
[0003] Both solar thermal power generation systems and thermal power generation systems require strict control of water vapor quality to prevent corrosion and salt accumulation in power generation equipment. Currently, under both power generation modes, the main methods of water vapor monitoring are online monitoring and sampling monitoring. Online detection instruments are commonly used in major power plants. They can monitor water vapor quality in a timely manner and control water vapor quality based on the test results. However, they have high maintenance costs and require regular calibration by dedicated personnel. They are only suitable for various large-scale power generation companies. Sampling monitoring is more common. Generally, in-plant laboratory personnel take samples from sampling racks and send them to the laboratory for multiple indicator tests. However, the sampling and transportation process is prone to sample contamination, resulting in distorted monitoring results.
[0004] Both CSP and thermal power generation units involve the use of specialized equipment, including high temperature and high pressure. While thermal power generation units are more maturely regulated, emerging CSP units still face certain regulatory gaps. Currently, various regions are gradually including CSP equipment within the scope of special equipment safety supervision. Currently, supervisory agencies primarily conduct inspections based on sampling, which poses challenges in timeliness and accuracy. There is an urgent need for a portable, flexible, and accurate multi-parameter water quality testing instrument to assist special equipment inspectors in their work, enabling rapid testing of boiler water vapor indicators. Any identified issues can be promptly notified to the company for investigation and resolution, ensuring the safe and energy-efficient operation of special equipment. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0034] Example 1
[0035] This embodiment provides an integrated water vapor quality detection device suitable for a power generation system, including an automatic sampler 1, an anion detection unit, a cation detection unit and a workstation 2. Figure 1The automatic sampler 1 has an anion injection port and a cation injection port; the anion detection unit includes a first elution container 3, a first pump body 4, an anion protection column 5, an anion separation column 6, an anion suppressor 7, a first conductivity cell 8 and a first conductivity detector 9. The first elution container 3 is used to store anion eluent. The first elution container 3 is connected to the anion protection column 5 via the first pump body 4. The anion injection port is also connected to the anion protection column 5. The anion protection column 5 is connected to the anion separation column 6 and the anion suppressor 7 is connected to the first conductivity detector 9 via the first conductivity cell 8; the cation detection unit includes a second elution container 10, a second pump body 11, a cation protection column 12, an anion separation column 6, an anion suppressor 7, a first conductivity cell 8 and a first conductivity detector 9. An ion separation column 13, a cation suppressor 14, a second conductivity cell 15 and a second conductivity detector 16; the second elution container 10 is used to store a cationic eluent; the second elution container 10 is connected to the cation protection column 12 via a second pump body 11; the cation injection port is also connected to the cation protection column 12; the cation protection column 12 is connected to the cation suppressor 14 via the cation separation column 13; the cation suppressor 14 is connected to the second conductivity detector 16 via the second conductivity cell 15; the first conductivity detector 9 and the second conductivity detector 16 are both communicatively connected to the workstation 2; the workstation 2 can receive the detection data of the first conductivity detector 9 and the second conductivity detector 16 and perform conversion analysis to obtain a spectrum.
[0036] The utility model is an integrated water vapor quality detection device suitable for power generation systems, and an anion detection unit and a cation detection unit are provided at the same time, and the sample is introduced before the separation column. The mobile phase carries the sample into the separation column, and the components are separated in the separation column and sequentially carried to the suppressor with the mobile phase. In the suppressor, the anions (cations) in the sample are converted into corresponding acids (bases), and the eluent ions are converted into water, which then flows into the conductivity cell for conductivity detection. The chemical signals of ions of different concentrations are converted into corresponding electrical signals with a high signal-to-noise ratio. After analog-to-digital conversion, the signal is sent to workstation 2 for data processing to obtain a spectrum. The utility model adopts a dual-path simultaneous detection working mode to realize the simultaneous detection of anions and cations, thereby improving the detection efficiency and enhancing the level of integration of the integrated water vapor quality detection device suitable for power generation systems.
[0037] In this specific embodiment, the anion detection unit uses the Na2CO3 and NaHCO3 system, and the cation detection unit uses the methanesulfonic acid system. The integrated design allows the two systems to operate simultaneously. After the device is turned on, the sample can be directly injected and the anion and cation detection results can be completed within 30 minutes. It can detect inorganic anions: F - 、Cl - 、NO2 - PO4 3- Br- 、SO4 2- 、NO3 - 、ClO2 - BrO3 - 、ClO3 - Etc., the types of inorganic cations detected are: Li + 、Na + NH4 + , K + , Ca 2+ Mg 2+ 、Sr 2+ 、Ba 2+ Different from the commonly used cationic nitric acid system and anionic potassium hydroxide system, it reduces the use of hazardous chemicals and highly corrosive chemicals, and is safe and environmentally friendly.
[0038] It should also be noted that the first rinsing container 3 and the second rinsing container 10 are both bag-type containers, and both the first rinsing container 3 and the second rinsing container 10 can be hung and fixed. The first rinsing container 3 and the second rinsing container 10 of the utility model both adopt an integrated design of bagged rinsing liquid, rather than the traditional design of rinsing liquid tank and rinsing reagent tank. The first rinsing container 3 and the second rinsing container 10 can both be hung and fixed inside the device, and the rinsing liquid enters the device after being sucked into the device by a high-pressure pump through the liquid inlet with a filter membrane. The rinsing liquid capacity can be selected according to the experimental conditions. The rinsing liquid bag is flat in design, small in size and low in manufacturing cost, which greatly reduces the volume occupied by the equipment and increases the portability of the equipment. At the same time, a hanging hook can be placed at the rinsing liquid bag position to hang the rinsing liquid bag in the internal cavity of the instrument. In addition, the rinsing liquid selected by the instrument can be prepared before the on-site equipment is used.
[0039] Specifically, the separation of various ions in the sample is completed in the separation column. The ion exchange resin filled in the anion separation column 6 is generally a PS-DVB copolymer with quaternary ammonium salt ion exchange functional groups. When the mobile phase solution containing carbonate and bicarbonate anions passes through the anion exchange column, the positively charged quaternary ammonium groups on the resin are all "occupied" by carbonate. - and B - When a sample is added to the separation column, an ion exchange equilibrium between the eluent anions and the sample anions occurs at the resin functional group position. This dynamic equilibrium is reversible, as shown below:
[0040]
[0041] Different anions have different interactions with the positively charged quaternary ammonium salt functional groups, that is, different retention values in the stationary phase, so different anions can be effectively separated.
[0042] There are two types of cation exchange resins: strong acid and weak acid. Strong acid cation exchange resins are generally sulfonated PS-DVB copolymers with sulfonic acid groups as their functional groups. Weak acid cation exchange resins have carboxyl or phosphorus groups as their functional groups, and their matrix is bonded silica spheres or PS-DVB copolymers. The separation principle of sulfonic acid type cation exchange resins is as follows:
[0043]
[0044] Where: M + Represents the cation to be measured in the sample.
[0045] Working principle of anion suppressor 7 and cation suppressor 14: water is electrolyzed to generate H + and OH - , under the action of the electric field, H + It can pass through the cation exchange membrane into the suppression chamber (Na2CO3, NaHCO3 aqueous solution), undergo acid-base neutralization reaction, and convert Na2CO3 into H2CO3, thereby reducing the background conductivity. + Passing through the cation exchange membrane into the cathode chamber, H + The combination of the ion to be detected and the anion to be detected is used to highlight the conductivity of the ion to be detected, thereby achieving the purpose of improving the detection sensitivity.
[0046] The traditional method for testing sodium ions is the electrode method. When sodium ion concentrations are low, electrode signals are susceptible to interference, resulting in distorted test data and poor data accuracy and repeatability. Furthermore, electrodes are prone to damage during storage and transportation, preventing timely testing and causing data distortion. This new integrated water vapor quality testing device, suitable for power generation systems, separates sodium ions from other interfering factors and generates a clear image, ensuring data accuracy.
[0047] For ease of control, the anion detection unit further includes a first electric valve 17, and the first pump body 4 and the anion inlet are both connected to the anion guard column 5 using the first electric valve 17. Correspondingly, the cation detection unit further includes a second electric valve 18, and the second pump body 11 and the cation inlet are both connected to the cation guard column 12 using the second electric valve 18. The first electric valve 17 and the second electric valve 18 can be six-way valves, and the first pump body 4 delivers the mobile phase to the anion detection unit at a stable flow rate, and the sample is introduced through the first electric valve 17 before the anion separation column 6. Correspondingly, the second pump body 11 delivers the mobile phase to the anion detection unit at a stable flow rate, and the sample is introduced through the second electric valve 18 before the cation separation column 13.
[0048] It should also be noted that the integrated water vapor quality detection equipment for power generation systems of the present invention also includes a waste liquid tank 19, to which both the anion suppressor 7 and the cation suppressor 14 are connected. The waste liquid tank 19 is used to collect and store waste liquid for centralized processing and pollution prevention. In other specific embodiments of the present invention, a waste liquid discharge pipeline can also be provided, through which the waste liquid generated by the anion suppressor 7 and the cation suppressor 14 is discharged. The discharge port can be connected to an external independent component such as a waste liquid barrel or waste liquid bag, thereby reducing the size of the instrument.
[0049] First conductivity cell 8 has a first reflux port connected to anion suppressor 7; correspondingly, second conductivity cell 15 has a second reflux port connected to cation suppressor 14. Providing the first reflux port in first conductivity cell 8 and the second reflux port in second conductivity cell 15 helps reduce the formation of bubbles in first conductivity cell 8 and second conductivity cell 15, which could interfere with conductivity measurement and affect analytical results. The first and second conductivity cells 8 and 15 also use the first and second reflux ports to drain wastewater, preventing wastewater accumulation.
[0050] In this embodiment, the first conductivity detector 9 and the second conductivity detector 16 are both pentode conductivity detectors. The principle of the pentode conductivity detector is as follows: Figure 2 As shown, in the conductivity cell, the operating current generated by the oscillating source passes through a current electrode 18 and a sampling resistor. Two potential electrodes 19 are located between the two current electrodes 18. The potential between the electrodes is maintained constant by controlling the current. A voltage signal proportional to the conductivity of the conductivity cell solution is obtained at the sampling resistor. After amplification and A / D conversion, it is input to the workstation 2 to obtain a spectrum. This effectively eliminates the effects of electrode polarization and double-layer capacitance on conductivity measurement, improving the signal-to-noise ratio of the measured signal. In practical applications, conductivity detectors of other specifications may also be used. The selection and setting of operating parameters for pentapolar conductivity detectors and other conductivity detectors are conventional methods used by those skilled in the art and will not be further described here.
[0051] In this specific embodiment, both the first pump body 4 and the second pump body 11 utilize high-pressure horizontal flow pumps, addressing the need for conventional benchtop ion chromatographs to operate in a degassing and pressurizing mode using gas cylinders, thereby facilitating field use. In practical applications, other pump types can be selected based on specific testing conditions to meet the requirements of equipment testing. The selection and adjustment of parameters for high-pressure horizontal flow pumps and other pump types are well within the skill of those skilled in the art and will not be further elaborated here.
[0052] It should also be noted that the integrated water vapor quality detection device for power generation systems of the present invention can be connected to an external power source to ensure the normal operation of the device. In actual use, the integrated water vapor quality detection device for power generation systems of the present invention can also be equipped with a battery. The battery is removably installed inside the device, and the battery is used to ensure the power supply of the device when it is inconvenient to connect to an external power source. In this specific embodiment, the battery power supply lasts for 8 hours. In actual application, the appropriate battery specifications can be selected according to the specific working conditions to improve the flexibility and adaptability of the device.
[0053] In other specific embodiments that can be implemented by the present invention, the water vapor quality integrated detection device suitable for power generation systems of the present invention also includes a controller, and the automatic sample injector 1, the anion detection unit, the cation detection unit and the workstation 2 are all communicatively connected to the controller, and the anion detection unit and the cation detection unit are arranged in parallel. According to actual detection needs, the controller can be used to control the working state of the anion detection unit and the cation detection unit to meet different detection conditions and improve the flexible adaptability of the equipment. It should be explained here that the structure and working mode of the controller are both common means of those skilled in the art and will not be repeated here.
[0054] In addition, the integrated water vapor quality detection device for power generation system of the present invention also includes a box 22, see Figure 3 and Figure 4 , the automatic sampler 1, the anion detection unit, the cation detection unit and the workstation 2 are all arranged in the box body 22, which further improves the integration level of the equipment and enhances the portability of the equipment, so that the water vapor quality integrated detection equipment suitable for the power generation system of the present invention can adapt to various on-site detection conditions. In actual applications, a liquid level observation window 23 can be provided on the box body 22 to facilitate the observation of the liquid level changes of the eluent in the first elution container 3 and the second elution container 10. In the specific implementation method that can be realized by the present invention, the box body 22 can be set to a split structure, which is convenient for the disassembly and assembly of the various components inside the box body 22, provides convenience for subsequent cleaning and maintenance, and facilitates the application of the water vapor quality integrated detection equipment suitable for the power generation system. In this specific implementation method, the box body 22 adopts a rectangular structure, and the specifications of the box body 22 are: 50 cm long, 27 cm wide, and 62 cm high. In actual applications, it can also be adjusted according to actual needs. The anion detection unit and the cation detection unit share the workstation 2 and the controller, which improves the degree of equipment integration, reduces the space occupied by the equipment, and improves the portability and flexible adaptability of the integrated water vapor quality detection equipment suitable for power generation systems.
[0055] In practical applications, the housing 22 includes a first cavity and a second cavity. The utility model is suitable for integrated water vapor quality detection equipment for power generation systems, and the anion detection unit and the cation detection unit are two independent piping systems. Based on the volume of the components, the pump body, detector, and separation column are fixed in the first cavity, and the automatic sampler 1 and suppressor are fixed in the second cavity, making full use of the limited space within the instrument housing 22, making the overall structure more compact and convenient for outdoor portability. The two sets of system components can be uniformly controlled by the same circuit control system, but the two systems can operate independently. At the same time, depending on the on-site sample conditions, the detector can be selected and replaced between the conductivity cell and the voltammetric cell, thereby realizing the switching between the electrochemical method and the voltammetric method.
[0056] In the existing inspection process, in order to ensure the timeliness of the inspection data of calcium and magnesium hardness, sodium, chloride ions, sulfate, organic acid ions, phosphate, etc., a large amount of equipment, reagents and corresponding consumables need to be carried. After the inspection is completed, the water vapor samples retrieved on site need to be carried to a temporary laboratory for inspection. The inspection process is cumbersome and time-consuming. The use of the integrated water vapor quality detection equipment suitable for power generation systems of the utility model can reduce most of the material transportation, and various water vapor samples can be inspected directly on site. After opening, the sampling can be directly operated to avoid contamination during storage and transportation, and various test indicators can be completed simultaneously within thirty minutes. The entire inspection process does not require any other manual operations except sampling, which greatly reduces the workload of the inspectors. After obtaining the inspection data on site, the inspectors can feedback the problems to the enterprise operation and maintenance personnel in real time so that the problems can be solved in a timely manner, avoiding the phenomenon that feedback cannot be given in time after the problems are discovered and the timeliness of the data cannot be guaranteed.

High-performance detectors are also used to ensure accurate detection results.
[0059] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
