[0042] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] The embodiment of the present application provides a water vapor sampling and detection device, which is used to sample and detect water vapor from a water vapor system, and the device can recover the condensed water of the sampled water vapor and mix the condensed water into the circulating cooling water. Compared with the method of using circulating cooling water alone as a cooling medium, the mixing of condensed water into the circulating cooling water can reduce the amount of circulating cooling water, thereby improving the water quality of the cooling medium and improving the heat exchange effect. Moreover, in local high-temperature areas, the mixing of condensed water into the circulating cooling water can also reduce the overall temperature of the cooling medium, thereby improving the cooling effect and reducing the burden on the rear-end compressor. Specifically, the device can improve the problem of hidden dangers in the operation of the high-temperature sampling rack of the existing water vapor sampling and detection device due to the high temperature and poor water quality of the circulating cooling water.

[0044] refer to Figure 1The water vapor sampling and detection device comprises: a cooler 1, a sampling and detection unit, a sample water recovery box 4 and a circulating cooling water source 5. The sampling port of the cooler 1 is used to connect to the sampling point of the water vapor system, and the sampling port of the cooler 1 is connected to the water inlet of the sampling and detection unit. The water outlet of the sampling and detection unit is connected to the water inlet of the sample water recovery box 4. The water outlet of the sample water recovery box 4 and the water outlet of the circulating cooling water source 5 are respectively connected to the water inlet of the cooler 1. During use, the water vapor sample first passes through the cooler 1 to cool down, and then flows into the sampling and detection unit. After the sampling and detection unit completes the detection and sampling, the water vapor sample flows into the sample water recovery box 4 and condenses into water. Finally, the condensed water can be mixed with the circulating cooling water as part of the cooling medium. In this way, the condensed water can be used to improve the water quality of the cooling medium and reduce the temperature of the cooling medium, thereby improving the problem that the high temperature sampling rack operation of the existing water vapor sampling and detection device due to the high temperature and poor water quality of the circulating cooling water causes hidden dangers.

[0045] It should be noted that, limited by the requirements of the sampling and detection unit on the temperature of the water vapor sample, the temperature of the cooled water vapor sample is generally 25±1°C, and its condensed water can be used as a cooling medium.

[0046] In some embodiments, the sample inlet of the cooler 1 is provided with a first stop valve 6. Specifically, when the first stop valve 6 is opened, water vapor can enter the cooler 1 through the first stop valve 6 for sampling and detection. When the first stop valve 6 is closed, water vapor cannot pass through the first stop valve 6, and subsequent sampling and detection operations cannot be performed. Furthermore, the number of the first stop valves 6 is two, and the two first stop valves 6 are arranged in series. This arrangement ensures that the normal use of the device can be guaranteed even if one of the stop valves fails, which can reduce the failure rate of the device and improve the reliability of the device.

[0047] In some embodiments, the water outlet of the sample water recovery tank 4 is provided with a recovery water pump 16. During use, the recovery water pump 16 can pump the condensed water in the sample water recovery tank 4 into the cooler 1.

[0048] In some embodiments, the sampling and detection unit includes an online chemical meter 2 and a manual sampling tray 3, and the online chemical meter 2 and the manual sampling tray 3 are arranged in parallel. Specifically, the online chemical meter 2 and the manual sampling tray 3 are respectively arranged on two pipelines, and the two pipelines are respectively connected between the sample outlet of the cooler 1 and the water inlet of the sample water recovery box 4. During use, the water vapor sample after cooling can be divided into two paths, one path passes through the online chemical meter 2, and the other path passes through the manual sampling tray 3, and finally the two paths of water vapor samples both reach the sample water recovery box 4. In the above process, the online chemical meter 2 can monitor and analyze the concentration of chemical substances, pH value, conductivity, dissolved oxygen and other parameters in the water vapor sample in real time, and the manual sampling tray 3 can be used for operators to take samples to the laboratory for testing.

[0049] In some embodiments, the water inlet of the online chemical instrument 2 is provided with a second stop valve 7. When the temperature of the water vapor sample exceeds the limit value, the second stop valve 7 can close the water inlet of the online chemical instrument 2, so as to prevent the online chemical instrument 2 from being damaged due to the excessive temperature of the water vapor sample. It should be understood that in a specific implementation, a temperature sensor can be provided upstream of the second stop valve 7 to detect the temperature of the water vapor sample flowing out of the cooler 1.

[0050] In some embodiments, the water vapor sampling and detection device also includes: a first temperature sensor 8, a second temperature sensor 9, a temperature pressure regulating valve 10 and a controller 11. The first temperature sensor 8 is arranged at the sample outlet of the cooler 1, and is used to monitor the sample outlet temperature of the cooler 1. The second temperature sensor 9 is arranged at the water outlet of the sample water recovery box 4, and is used to monitor the outlet water temperature of the sample water recovery box 4. The temperature pressure regulating valve 10 is arranged at the water outlet of the circulating cooling water source 5, and is used to adjust the outlet water temperature of the circulating cooling water source 5. The controller 11 is electrically connected to the first temperature sensor 8 and the temperature pressure regulating valve 10 respectively, and is used to control the temperature pressure regulating valve 10 according to the monitoring information to adjust the outlet water temperature of the circulating cooling water source 5. For example, when the temperature of the water vapor sample flowing out of the cooler 1 exceeds the limit value, the controller 11 can control the temperature pressure regulating valve 10 to reduce the outlet water temperature of the circulating cooling water source 5. For another example, when the outlet water temperature of the sample water recovery box 4 gradually increases, so that the temperature of the water vapor sample flowing out of the cooler 1 exceeds the limit, the controller 11 can control the temperature pressure regulating valve 10 to reduce the outlet water temperature of the circulating cooling water source 5. This arrangement can facilitate the control of the temperature of the cooling medium to meet the cooling needs.

[0051] It should be understood that in a specific implementation, the controller 11 can also be electrically connected to the second stop valve 7. When the temperature of the water vapor sample flowing out of the cooler 1 exceeds the limit, the controller 11 can promptly control the second stop valve 7 to close the water inlet of the online chemical instrument 2. Compared with the manual operation method, this can increase the reaction speed and reduce the risk of damage to the chemical instrument.

[0052] In some embodiments, the water vapor sampling detection device further includes: a first flow sensor 13, a first flow regulating valve 12, a second flow sensor 15 and a second flow regulating valve 14. The first flow regulating valve 12 is arranged at the outlet of the sample water recovery box 4, and is used to adjust the water outlet flow rate of the sample water recovery box 4. The first flow sensor 13 is arranged at the outlet of the first flow regulating valve 12, and is used to monitor the water outlet flow rate of the sample water recovery box 4. The second flow regulating valve 14 is arranged at the outlet of the circulating cooling water source 5, and is used to adjust the water outlet flow rate of the circulating cooling water source 5. The second flow sensor 15 is arranged at the outlet of the second flow regulating valve 14, and is used to monitor the water outlet flow rate of the circulating cooling water source 5. The controller 11 is electrically connected to the first flow regulating valve 12, the first flow sensor 13, the second flow regulating valve 14 and the second flow sensor 15 respectively, and is used to control the first flow regulating valve 12 and the second flow regulating valve 14 according to the monitoring information to adjust the water outlet flow rate of the sample water recovery box 4 and the water outlet flow rate of the circulating cooling water source 5. For example, when the temperature of the water vapor sample flowing out of the cooler 1 exceeds the limit, the controller 11 can control the temperature pressure regulating valve 10, the first flow regulating valve 12 and the second flow regulating valve 14 to reduce the water flow rate of the sample water recovery tank 4 and increase the water flow rate of the circulating cooling water source 5 while reducing the temperature of the circulating cooling water. This arrangement can facilitate further reducing the temperature of the cooling medium.

[0053] It should be understood that in a specific implementation, the controller 11 can also control the first flow regulating valve 12 and the second flow regulating valve 14 when the outlet water temperature or the outlet water flow rate of the sample water recovery box 4 changes.

[0054] The present application also provides a sampling detection method, which is applicable to a water vapor sampling detection device, and the method includes:

[0055] Step 100, sample water treatment, the circulating cooling water source 5 outputs circulating cooling water, and the sample water recovery tank 4 outputs recovered sample water. The circulating cooling water and the recovered sample water exchange heat with the water vapor sample in the cooler 1 to cool the water vapor sample to the set temperature.

[0056] Step 200, water sample detection, the cooler 1 sends the cooled water vapor sample to the sampling detection unit, and the sampling detection unit detects and samples the water vapor sample.

[0057] Step 300, sample water recovery, the sampling and detection unit sends the remaining water vapor sample to the sample water recovery box 4, and the water vapor sample condenses into water in the sample water recovery box 4 for heat exchange with the water vapor sample.

[0058] In step 100 , the first temperature sensor 8 monitors the outlet temperature of the cooler 1 , the second temperature sensor 9 monitors the outlet temperature of the sample water recovery tank 4 , and the controller 11 controls the temperature pressure regulating valve 10 according to the monitoring information to adjust the outlet temperature of the circulating cooling water source 5 .

[0059] In step 100 , during the sample water treatment process, the controller 11 also controls the first flow regulating valve 12 and the second flow regulating valve 14 according to the monitoring information to adjust the outflow flow of the sample water recovery tank 4 and the outflow flow of the circulating cooling water source 5 .

[0060] According to the above scheme, the water vapor sampling and detection device can sample and detect water vapor from the water vapor system. In addition, the device can recycle the condensed water of the sampled water vapor and mix the condensed water into the circulating cooling water. Compared with the method of using circulating cooling water alone as the cooling medium, the mixing of condensed water into the circulating cooling water can reduce the amount of circulating cooling water, thereby improving the water quality of the cooling medium and improving the heat exchange effect. Moreover, in local high-temperature areas, the mixing of condensed water into the circulating cooling water can also reduce the overall temperature of the cooling medium, thereby improving the cooling effect and reducing the burden on the rear-end compressor. Specifically, the device can improve the problem of hidden dangers in the operation of the high-temperature sampling rack caused by the high temperature and poor water quality of the circulating cooling water in the existing water vapor sampling and detection device.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification should be included in the scope of protection of this application.
