[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0036] Please refer to the attached Figures 1-2 The embodiment of the present application provides an in-situ humidity analyzer 100, which is used to measure the humidity of desulfurization and denitrification flue gas in an online continuous flue gas monitoring system.

[0037] Please refer to the attached Figures 1-2 In an embodiment of the present application, the in-situ humidity analyzer 100 includes a bracket 10, an in-situ humidity analysis component 20 and a humidity sensor module 30. The bracket 10 is located between the in-situ humidity analysis component 20 and the humidity sensor module 30. At this time, the in-situ humidity analysis component 20 and the humidity sensor module 30 are respectively connected to the bracket 10. The in-situ humidity analysis component 20 is located on the outside of the chimney, and the humidity sensor module 30 is located on the inside of the chimney. The humidity sensor module 30 is electrically connected to the in-situ humidity analysis component 20 so that the humidity sensor module 30 senses the situation inside the chimney and transmits it to the in-situ humidity analysis component 20. The in-situ humidity analysis component 20 performs a situation analysis on the inside of the chimney.

[0038] Please refer to the attached Figure 2 and 3In the embodiment of the present application, the bracket 10 serves as a supporting component of the in-situ humidity analyzer 100. The bracket 10 is used to support the in-situ humidity analysis component 20 and the humidity sensor module 30. The bracket 10 is provided with a probe portion 11, a first support portion 12 and a second support portion 13. The probe portion 11 is passed through the chimney. The first support portion 12 is located on the outside of the chimney and supports the in-situ humidity analysis component 20. The second support portion 13 is located in the internal flue of the chimney and supports the humidity sensor module 30.

[0039] Please refer to the attached Figures 1-2 In an embodiment of the present application, the in-situ humidity analysis component 20 is installed on the first support portion 12 and is located on the outside of the chimney, so that the in-situ humidity analysis component 20 can be connected to the bracket 10 through the first support portion 12.

[0040] Please refer to the attached Figures 2-4 In the embodiment of the present application, the humidity sensor module 30 is installed on the second support portion 13 and is located in the internal flue of the chimney, so that the humidity sensor module 30 can be connected to the bracket 10 through the second support portion 13.

[0041] At this time, the humidity sensor module 30 includes a mounting base 31, a humidity sensor 32, a filter cap 33 and a filter core 34. The humidity sensor 32 is mounted on the mounting base 31 and is electrically connected to the in-situ humidity analysis component 20. The mounting base 31 is mounted on the second support portion 13. The filter cap 33 is mounted on the mounting base 31 and covers the humidity sensor 32. The filter core 34 is built into the filter cap 33 and, combined with the filter cap 33, performs multiple annular filtration on the flue gas in the internal flue of the chimney, so that the filter cap 33 and the filter core 34 protect the sensing end of the humidity sensor 32 to prevent the flue gas in the internal flue of the chimney from directly impacting the sensing end of the humidity sensor 32, thereby performing multiple safety protections on the sensing end of the humidity sensor 32 to prevent the humidity sensor 32 of the in-situ hygrometer from being damaged, thereby ensuring the performance of the humidity sensor 32 of the in-situ hygrometer.

[0042] Please refer to the attached Figures 2-4 , wherein the filter cap 33 and the filter core 34 are arranged in a ring shape, and the filter cap 33 forms a first annular filtering space, so that the filter core 34 combines with the filter cap 33 to perform annular filtering on the smoke in the internal flue of the chimney. The filter cap 33 is provided with an opening, and the smoke in the internal flue of the chimney is filtered for the first time through the opening of the filter cap 33, so as to achieve the first filtration of the smoke in the internal flue of the chimney.

[0043] Please refer to the attached Figures 2-4In addition, a metal barrier 331 is provided on the outer wall of the filter cap 33. The metal barrier 331 blocks the smoke in the internal flue of the chimney and allows part of the smoke to enter the internal space of the filter cap 33 through the opening of the filter cap 33. The metal barrier 331 blocks the rising smoke and diverts the rising smoke along the length direction of the metal barrier 331. At this time, when the smoke carrying various solid and liquid pollutants rushes upward from the bottom of the chimney, the metal barrier 331 can change the rising path of the solid and liquid pollutants with the airflow, and continue to move upward through the two side edges of the metal barrier 331, thereby preventing the solid and liquid pollutants from directly impacting the filter element 34.

[0044] Please refer to the attached Figures 2-4 Furthermore, the filter core 34 is located within the interior space of the filter cap 33 and performs a second filtration on the flue gas entering through the opening of the filter cap 33, so that the flue gas in the chimney's internal flue is sequentially filtered through the opening of the filter cap 33 and the filter core 34. This facilitates the filter core 34 and the filter cap 33 to perform multiple annular filtration on the flue gas in the chimney's internal flue, thereby improving the filtering effect of the in-situ humidity analyzer 100. Optionally, the filter core 34 is a cylindrical metal dust sintered filter core. At the same time, the filter cap 33 has a built-in filter portion, which is located on one side of the filter cap 33 and arranged along the same axial direction. The filter portion is located outside the sensing end of the humidity sensor 32.

[0045] Please refer to the attached Figures 2-4 , wherein the humidity sensor 32 is passed through the mounting seat 31, and the filter core 34 is detachably mounted on the filter cap 33, so that the filter core 34 can be connected to or detached from the filter cap 33. When the filter core 34 is detached from the filter cap 33, the filter core 34 can be replaced, which improves the convenience of replacing the filter core 34. When the filter core 34 is connected to the filter cap 33, the filter core 34 covers the sensing end of the humidity sensor 32, so that the filter core 34 protects the sensing end of the humidity sensor 32 to prevent the flue gas in the internal flue of the chimney from directly impacting the sensing end of the humidity sensor 32. The filter core 34 is detachably connected to the filter cap 33 by a threaded connection.

[0046] Please refer to the attached Figures 2-4The filter cap 33 is detachably mounted on the mounting seat 31 and is located on the outer peripheral side of the filter element 34, so that the filter cap 33 can be connected to or detached from the mounting seat 31, thereby facilitating the replacement of the filter cap 33 and improving the convenience of replacing the filter cap 33. The mounting position between the filter cap 33 and the mounting seat 31 is located outside the mounting position between the filter cap 33 and the mounting seat 31 and the mounting position between the mounting seat 31, so that the filter cap 33 and the filter element 34 can protect the sensing end of the humidity sensor 32 and prevent the flue gas in the internal flue of the chimney from directly impacting the sensing end of the humidity sensor 32, thereby providing multiple safety protections for the sensing end of the humidity sensor 32, preventing the humidity sensor 32 of the in-situ hygrometer from being damaged, and ensuring the performance of the humidity sensor 32 of the in-situ hygrometer. The filter cap 33 is detachably connected to the mounting seat 31 by a threaded connection.

[0047] Please refer to the attached Figures 1-2 In an embodiment of the present application, the probe rod portion 11 is horizontally penetrated in the chimney, the humidity sensor 32 is electrically connected to the in-situ humidity analysis component 20, and a conductive member is provided between the humidity sensor 32 and the in-situ humidity analysis component 20, so that the humidity sensor 32 can be electrically connected to the in-situ humidity analysis component 20 through the conductive member, thereby facilitating the transmission of the situation sensed by the humidity sensor 32 to the in-situ humidity analysis component 20, and the conductive member is penetrated through the probe rod portion 11 so that the outer surface of the probe rod portion 11 can protect the conductive member.

[0048] Please refer to the attached Figure 5 The probe portion 11 is in the shape of a tube and is provided with an internal pipe 11a. The internal pipe 11a is used for the conductive member to pass through, so that the conductive member can pass through the probe portion 11 through the internal pipe 11a. Optionally, the conductive member is a conductive wire.

[0049] In an embodiment of the present application, the mounting seat 31 is sealed and connected to the second support portion 13, and a sealing ring is provided between the mounting seat 31 and the second support portion 13. The mounting seat 31 and the second support portion 13 squeeze the sealing ring respectively, so that the mounting seat 31 can be sealed and connected to the second support portion 13 through the sealing ring, thereby preventing smoke from entering the humidity sensor 32 through the connection between the mounting seat 31 and the second support portion 13.
