[0038] The cooling water outlet main pipe 2 is installed on the top of the support assembly 1; specifically, it is arranged on the support seat 13 for the outflow of cooling water.

[0039] The cooling water inlet main pipe 3 is installed in the support assembly 1 and is located below the cooling water outlet main pipe 2; specifically, it is penetrated in the multi-channel support vertical frame 12 and is parallel to the cooling water outlet main pipe 2 for inputting cooling water.

[0040] There are multiple groups of installation modules 4, and their specific number is not limited and can be determined according to the user's usage scenario and needs. Each group of installation modules 4 is detachably mounted on the support assembly 1 and is located between the cooling water outlet mother pipe 2 and the cooling water inlet mother pipe 3. Its detachable method can adopt existing conventional methods, such as a combination of bolts and nuts, a clamping structure, etc.; in this embodiment, each group of installation modules 4 includes a plurality of slot rods 41 (two slot rods arranged up and down in this embodiment) installed in the support assembly 1 or on its side and arranged at intervals, and a support plate 42 detachably mounted on the plurality of slot rods 41, a slot is arranged on the surface of the slot rod 41, and a clamping screw matching the slot is formed on the support plate 42.

[0041] The sampling assembly 6 includes a plurality of sampling trays installed on each group of mounting modules 4 (i.e., the sampling trays correspond to the mounting modules 4 one by one). The above-mentioned sampling trays include a matching cooling unit 61 and an adjusting unit 62. The cooling unit 61 includes a cooler 611 detachably mounted on the mounting module 4 (the detachable method here can also be conventional, such as a combination of bolts and nuts, etc.) and a three-way valve 614 connected to the cooler 611 through a first water pipe 612 and connected to the cooling water inlet main pipe 3 (when the three-way valve 614 is adjusted in this way, the cooling water inlet main pipe 3 and the cooler 611 can be connected, so that the cooling water in the cooling water inlet main pipe 3 flows into the cooler 611 through the first water pipe 612); and the cooler 611 is also connected to the cooling water outlet main pipe 2 through a second water pipe 613, so that the cooling water after flowing through the cooler 611 for heat exchange can flow to the cooling water outlet main pipe 2 through the second water pipe 613 and then be discharged. The regulating unit 62 includes a filter 624 detachably mounted on the mounting module 4 and connected to the cooler 611 through a first drainage pipe 621 (the detachable manner is the same as above), an over-temperature shut-off valve 623 connected to the filter 624, a first three-way pipe 625 connected to the over-temperature shut-off valve 623, a second drainage pipe 620 connected to the cooler 611 at one end, a second three-way pipe 626 connected to the other end of the second drainage pipe 620 and having an injection port, and a first drainage pipe 621 connected to the cooler 611 at one end, so that the soda sample to be tested can be introduced into the cooler 611 through the second drainage pipe 620 via the injection port of the second three-way pipe 626 (the injection port of the second three-way pipe 626 can be connected to a pipeline through which the soda sample flows through the drainage pipe) for heat exchange, and then flow out of the cooler 611 through the first drainage pipe 621.

[0042] The low-temperature drainage assembly 5 is used to receive the water output from multiple three-way valves 614; in actual use, it is necessary to drain the water in the cooler 611. Since the low-temperature drainage assembly 5 is correspondingly located below the multiple three-way valves 614, at this time, the water in the cooling water inlet main pipe 3 can be drained to the low-temperature drainage assembly 5 by adjusting the three-way valve 614. Specifically, the low-temperature drainage assembly 5 may include a water collection tank 51 installed on the support assembly 1 (such as between multiple support vertical frames 12) and located below the cooling water inlet main pipe 3, multiple low-temperature outlet pipes 52 connected to the bottom of the water collection tank 51, and a low-temperature outlet main pipe 53 connected to the ends of the multiple low-temperature outlet pipes 52, so that the received low-temperature water is discharged through the low-temperature outlet main pipe 53.

[0043] In this embodiment, it also includes a constant temperature component, which is respectively connected to the cooling water inlet main pipe 3 and the cooling water outlet main pipe 2 to achieve constant temperature of cooling water to ensure cooling effect. The cooling unit 61 also includes a first stop valve 615 installed on the second water pipe 613, which is used to adjust the water flow in the second water pipe 613; and the regulating unit 62 also includes a flow meter 626 connected to the first three-way pipe 625, which can be used to measure the flow of the soda water sample to be tested. The regulating unit 62 also includes a second stop valve 628 installed on the second drainage pipe 620 and located between the second three-way pipe 626 and the cooler 611, and a high-pressure valve 627 connected to the second three-way pipe 626; the regulating unit 62 also includes a pressure reducing valve 622 connected to the first drainage pipe 621 (the pressure reducing valve 622 and the first drainage pipe 621 can be connected in a conventional manner, such as a three-way valve, etc.); the modular steam-water sampling device also includes a high-temperature sewage main pipe 7 connected to the high-pressure valve 627 through a pipeline; the above measures can enrich the function of the regulating unit 62, so that the high-temperature and high-pressure sample water can be measured and analyzed after effective temperature and pressure reduction.

[0044] In this embodiment, if Figure 5-10 As shown, each group of regulating units 62 has a regulating pipeline 11, and the regulating pipeline 11 is sequentially provided with a sampling point 101, a drain outlet II 102, a stop valve II 103, a stop valve III 104, a three-way pipe 113 and a pressure reducing valve 105; the three-way pipe 113 includes a pipe port I 1132, a pipe port II 1133 and a pipe port III 1131; the sampling point 101 is connected to the pipe port III 1131, the drain outlet II 102 is connected to the pipe port I 1132, and the stop valve III 104 is connected to the pipe port II 1133. The stop valve II103 is between the pipe port I1132 and the drain port II102. The stop valve II103 can be a high-temperature drain valve and is in a normally closed state. If the sample water quality is poor when starting the machine, the high-temperature sample water or steam from the upstream can be discharged to flush the pipeline; the stop valve III104 is a sample injection valve and is in a normally open state. When the pipeline is closed or maintained, the sample water is blocked. One end of the pressure reducing valve 105 is connected to the cooler through a pipeline. The pressure reducing valve 105 can adopt a needle valve structure. The flow control range of the pressure reducing valve 105 is 150ml / min~4L / min, which is used to adjust the pressure of the sample water.

[0045] The temperature protection valve 114 includes a temperature protection valve I 106 and a temperature protection valve II 107. The temperature protection valve 114 is connected to the other end of the pressure reducing valve 105. The temperature protection valve 114 regulates and controls the sample water temperature, including two schemes:

[0046] Solution 1

[0047] The temperature protection valve Ⅰ106 is connected to the other end of the pressure reducing valve 105. The temperature protection valve Ⅰ106 includes a filter Ⅰ1061 and a temperature shut-off valve 1062 (a temperature alarm 1063 may also be provided as required). One end of the filter Ⅰ1061 is connected to the other end of the pressure reducing valve 105. The filter Ⅰ1061 may use a filter with a filter area of ​​600 mm2 and a mesh of 140 microns to filter impurities and protect downstream components from damage. The other end of the filter Ⅰ1061 is connected to the temperature shut-off valve 1062. The temperature shut-off valve 1062 may use a mechanical temperature shut-off valve with a pressure tolerance of 350 bar. The temperature alarm 1063 is provided on one side of the temperature shut-off valve 1062 and cooperates with the temperature shut-off valve 1062. When the temperature shut-off valve 1062 exceeds the set shut-off temperature, the temperature alarm 1063 sends an alarm to the outside world.

[0048] Solution 2

[0049] The temperature protection valve II 107 is connected to the other end of the pressure reducing valve 105. The temperature protection valve II 107 includes a filter II 1071, a solenoid valve 1072, a digital temperature controller 1073 and a temperature electrode 1074. One end of the filter II 1071 is connected to the other end of the pressure reducing valve 105. The filter II 1071 can use a filter screen area of ​​600mm 2 , a filter with a mesh size of 140 microns is used to filter impurities and protect downstream components from damage. The other end of the filter II 1071 is connected to the solenoid valve 1072, and the digital display thermostat 1073 is connected to the other end of the solenoid valve 1072. When the solenoid valve 1072 is closed, it can withstand the maximum design pressure of the sampling point. It is usually controlled and operated by the digital display thermostat 1073. The solenoid valve 1072 can be switched by remote control. The temperature electrode 1074 is connected to the digital display thermostat 1073, and the digital display thermostat 1073 is installed in the main electrical cabinet. The digital display thermostat 1073 measures the temperature at the temperature electrode 1074, and at the same time judges the temperature to control the switch of the solenoid valve 1072. When the sample water temperature exceeds the set point (default 45°C), the solenoid valve 1072 is closed. At this time, the digital display thermostat 1073 will issue an alarm to request a manual reset operation. When an unexpected power failure occurs, the solenoid valve 1072 will be closed immediately to protect the safety of downstream instruments or other equipment. The temperature electrode 1074 can be a temperature sensor, and is in contact with the sample water, and can respond quickly to the temperature.

[0050] The regulating unit 62 also includes a back pressure valve 108 and a drain port III 109. The back pressure valve 108 includes at least a valve body II 1083, a valve body I 1084 and a bypass overflow port 1085. The back pressure valve 108 provides a stable sample water pressure of 0.5 bar for the instrument to ensure reliable and stable operation of the instrument. At the same time, it integrates 4 airtight film valves for diverting sample water to the instrument and manual sampling. The back pressure valve 108 can effectively ensure a stable sample water inlet pressure to prevent the current online instrument detection from being affected by changes in the unit load, manual sampling or operation of other instrument flow paths. At the same time, the back pressure valve 108 can quickly reach a stable pressure state, significantly reduce the waiting time of online instruments in the startup phase, and improve the economic benefits of the unit. The back pressure valve 108 can be used as a safety release valve, which can release a flow of 600L / H in a short time, while the back pressure output pressure will not increase significantly. Due to the constant pressure output to the instrument, the sample water flow of each instrument can be adjusted independently, which is not affected by system pressure fluctuations and will not affect the flow of other instruments.

[0051] Each group of regulating units 62 also has a cooling assembly 2 to cool the sample water. The cooling assembly 2 includes a cooling pipeline 21, on which are sequentially provided a cooling water inlet 201, a drain port I 202, a three-way valve 203, a cooler I 204, a check valve 2051, a flow monitor 2052, a stop valve I 2053 and a cooler II 207. The three-way valve 203 includes a port I 2031, a port II 2033 and a port III 2032. The cooling water inlet 201 is connected to the port I 2031, the drain port I 202 is connected to the port III 2032, and the cooler I 204 is connected to the port II 2033. When the three-way valve 203 is in a normal working state, the valve remains open so that cooling water can enter the cooler I 204. Port III 2032 is only used for maintenance operations. When the cooling water supply is interrupted, the cooling water in cooler I 204 can be normally discharged into the drain pipe through port III 2032. This can keep the water in cooler I 204 in a flowing state, and there is no need to equip each cooler with a pressure safety valve.

[0052] Cooler I 204 is disposed between stop valve III 104 and pressure reducing valve 105 to cool the sample water once.

[0053] The stop valve I2053 is connected to the cooler I204. The stop valve I2053 is installed downstream of the cooler I204 and is used to switch the cooling water. The other end of the stop valve I2053 is connected to the drain port IV206 for discharging the cooling water.

[0054] The check valve 2051 and the flow monitor 2052 are arranged between the stop valve Ⅰ 2053 and the cooler Ⅰ 204. The check valve 2051 is installed downstream of the cooler Ⅰ 204 to automatically cut off the flow and prevent the water of the cooling water outlet main pipe from flowing back to the cooler Ⅰ 204.

[0055] Cooler II 207 is arranged between the back pressure valve 108 and the temperature protection valve 114 to perform secondary cooling on the sample water.

[0056] Each group of regulating units 62 also has an analysis component 3 , which is connected to the back pressure valve 108 . The analysis component 3 includes an analysis unit 301 and a manual sampling point 302 .

[0057] The secondary cooled sample water is processed in three ways through the back pressure valve 108:

[0058] Method 1

[0059] The sample water is connected to the drain port III 109 through the bypass overflow port 1085 .

[0060] Method 2

[0061] The sample water is connected to the manual sampling point 302 through the valve body Ⅰ1084, and the manual sampling point 302 manually samples the sample water. At the same time, the manual sampling point 302 is connected to the drain port Ⅲ109.

[0062] Method 3

[0063] The sample water is connected to the analysis unit 301 through the valve body II 1083 , and the analysis unit 301 detects the sample water. Meanwhile, the analysis unit 301 is connected to the drain port III 109 .

[0064] The analysis unit 301 includes an instrument valve 3011, an ion exchange column 3012, a conductivity analyzer 3014, a temperature indicator 3013 and a flow indicator 3015, which are connected to the valve body II 1083 through a pipeline; that is, the instrument valve 3011 is installed on the pipeline, the ion exchange column 3012 is also installed on the pipeline and is located downstream of the instrument valve 3011, and the conductivity analyzer 3014, the temperature indicator 3013 and the flow indicator 3015 are connected to the pipeline in sequence and arranged in parallel (such as Fig.10As shown). The ion exchange column 3012 is used to exchange the sample water ions. The temperature indicator 3013 and the flow indicator 3015 monitor the temperature and flow of the sample water. The conductivity analyzer 3014 is used to measure the specific conductivity (sample water before cation exchange) and cation conductivity (sample water after cation exchange) in the sample water, and then detect the ions in the water. According to the monitoring requirements of "DL / T 246-2015 Chemical Supervision Guidelines", different analysis units can be configured, such as online pH analyzer, online sodium ion analyzer, online silicate analyzer, etc. The modular soda sampling device also includes an electrical control box connected to at least the sampling component 6, and the electrical control box is used to control the sampling component 6; specifically, it can complete the control of the over-temperature shut-off valve, the power distribution of the analytical instrument, the transmission of the analytical instrument, flow, and pressure signals, and other functions.

[0065] The modular steam-water sampling device of the present application has the following advantages: when the sample water is over-temperature, it is fully closed without any discharge port, ensuring the safety of personnel and chemical instruments. A three-way ball valve is used at the inlet of the cooler, which will not cut off the inner cavity of the cooler cylinder. When the sample water coil leaks and causes high-temperature and high-pressure sample water to enter the inner cavity of the cooler cylinder, the three-way ball valve is depressurized to connect the cooling water mother pipe or is in a discharge state. At the same time, a safety valve is set on the cooling water mother pipe to ensure that the cooling water will not be over-pressured. A pressure reducing valve plus a back pressure valve is adopted. The pressure reducing valve is responsible for reducing the pressure and throttling the high-pressure sample water. The back pressure valve is placed in the low-pressure sample water pipeline, responsible for stabilizing the pressure and flow, which is suitable for the unstable sample water pressure caused by the variable load operation of the generator set, and provides stable sample water conditions for the analytical instrument. A low-pressure back pressure valve is set in the low-pressure sample water pipeline, making it easier to adjust the sample water changes, without worrying about the damage to parts caused by the overpressure of the low-pressure sample water pipeline when the pressure reducing valve is operated improperly. The modular design is adopted. The high pressure valve, cooler, pressure reducing valve and other high pressures in the water sample are placed on a bottom plate to form a soda sampling tray. The parts can be replaced separately, and the soda sampling tray can also be replaced. A C-shaped groove is set to fix the soda sampling tray or instrument. There is no need to perform drilling, welding and other work during expansion. The modular soda sampling tray or analytical instrument is installed on the C-shaped groove. The pipeline and cable can be connected to expand a new water sample measurement point. The operation and maintenance of the sampling device can be completed on one side without entering the sampling device. The chain structure distribution is adopted, that is, all the parts on the water sample are arranged compactly up and down. During operation, the related parts can be observed and adjusted at the same time. For example, when calibrating the analytical instrument, the instrument flow cell and electrode are just below the transmitter, and there is no need to look for them elsewhere, making operation and maintenance more convenient and quick. The cooling water jelly pipe is connected to the cooler on the soda sampling tray with a high temperature and high pressure hose, which is more convenient when replaced. The high and low pressure sample water pipelines are special ferrules, and the connection is connected with double ferrules to ensure reliable connection and convenient replacement. The lower end of the sampling device adopts an integral stainless steel water collection tray (the same length as the device) to prevent the sample water from dripping during debugging and maintenance, ensure the dryness of the ground, and do not need to set up a special trench for the sampling device. Appropriate height control, the instrument transmitter is close to the height of the human eye, and the height of the main components is controlled between 0.8-1.7 meters, which is convenient for observation, operation and maintenance. A variety of optional parts, such as cooling water flow monitor, sample water total flow meter, double primary door, etc. The frame, bottom plate, water collection tank, cooling water pipeline, sample water pipeline, etc. are made of stainless steel to increase the service life of the device.

[0066] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
