[0025] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Reference Figure 1-8 A high-humidity flue gas generating device 100 for testing includes: a housing 101, a steam generator 102, an atomizer 103, a fan 104, a water pump 105, a filter assembly for filtering the inlet water of the water pump 105, and a control module 106. The housing 101 includes a flue 101a. The steam generator 102 is located inside the housing 101 and is fixedly connected to it. The atomizer 103 is located inside the housing 101 and is fixedly connected to it. The fan 104 is fixedly connected to the housing 101. The water pump 105 is fixedly connected to the housing 101. The water pump 105 includes an inlet pipe 105a and an outlet pipe 105b. The inlet pipe 105a is equipped with a filter assembly. The outlet pipe 105b is used to add water to the steam generator 102. The control module 106 is located on one side of the housing 101. The control module 106 is a microcontroller, which is connected to the steam generator 102, the atomizer 103, the water pump 105, and the water pump 105.

[0027] The flue 101a has a standard gas inlet 101b below it, which is used to transport polluted gas to the flue 101a. A sampling port 101c is located above the flue 101a. The steam generator 102 includes an evaporation tank with a first overflow pipe 102a on one side. The atomizer 103 includes an atomizing tank with a second overflow pipe 103a on one side. The first overflow pipe 102a is connected to the atomizing tank. An observation window 101d is located at the upper end of the housing 101, facilitating observation of the interior of the housing 101.

[0028] First, the evaporation tank and the atomization tank are filled with water using pump 105. Then, the water is evaporated using steam generator 102 and atomizer 103. The evaporated and atomized water vapor is mixed by fan 104 and then transported to flue 101a. Pollutant gas is also transported through standard gas inlet 101b and mixed with the water vapor. The high-humidity flue gas containing the target pollutant is discharged from flue 101a. The pollutant concentration is observed by the instrument. After stabilization, monitoring begins from sampling port 101c. Simultaneously, water is replenished to the evaporation tank and the atomization tank using pump 105.

[0029] The filter assembly is used to filter the water inlet pipe 105a of the water pump 105, and includes: a first end cap 107, a second end cap 108, a first rotating shaft 109, an adjusting disc 110, a filter screen 112, a filter layer 113, a first connecting pipe 114, a second connecting pipe 115, an adjusting member for adjusting the position of the adjusting disc 110, a locking member for locking the adjusting member, a limiting ring 116, and a limiting disc 117. The first end cap 107 is located on one side of the water pump 105 and is fixed to the water pump 105 by a support column. The second end cap 108 is threadedly connected to the housing 101. The first rotating shaft 109 is rotatably connected to the second end cap 108.

[0030] The regulating disc 110 is fixedly connected to the first end cap 107, and the regulating disc 110 has four mounting holes 110a. A filter screen 112 is located within the mounting holes 110a of the regulating disc 110. A filter layer 113 is located within the mounting holes 110a of the regulating disc 110 and is used to filter impurities in the water. The filter layer 113 is an activated carbon filter layer 113, which adsorbs small particulate impurities, thereby better filtering impurities in the water. A first connecting pipe 114 is fixedly connected to the first end cap 107. A second connecting pipe 115 is fixedly connected to the second end cap 108. A water inlet pipe 105a is fitted onto the first connecting pipe 114 and fixed with a clamp, and the second connecting pipe 115 is connected to an external water pipe and fixed with a clamp. A sealing ring is provided between the first connecting pipe 114 and the limiting disc 117 for sealing, and a sealing ring is provided between the second connecting pipe 115 and the regulating disc 110 for sealing.

[0031] The filter layer 113 and filter screen 112 have four corresponding mounting holes 110a. The first connecting pipe 114 and the second connecting pipe 115 are coaxially arranged. When the filtration effect decreases, the adjusting component drives the adjusting disc 110 to rotate so that different mounting holes 110a are coaxial with the first connecting pipe 114 and the second connecting pipe 115, so that the remaining filter screens 112 and filter layers 113 can filter the water. When the filtration effect of one of the filter screens 112 and filter layers 113 decreases, the adjusting component adjusts the remaining unused filter screens 112 and filter layers 113 to be coaxial with the first connecting pipe 114 and the second connecting pipe 115, thereby filtering the water in the inlet pipe 105a. The operation is convenient and the replacement is easy.

[0032] The adjusting component is used to adjust the position of the adjusting disc 110. The adjusting component includes: a second rotating shaft 118, a first rotating disc 119, a connecting block 120, a drive column 121, and a transmission disc 122. The second rotating shaft 118 is rotatably connected to the second end cover 108. The first rotating disc 119 is fixedly connected to the second rotating shaft 118. The connecting block 120 is fixedly connected to the first rotating disc 119. The drive column 121 is fixedly connected to the connecting block 120. The transmission disc 122 is fixedly connected to the first rotating shaft 109.

[0033] The transmission disc 122 includes a guide groove 122a. The drive column 121 drives the transmission disc 122 to rotate via the guide groove 122a, thereby adjusting the adjusting disc 110. The transmission disc 122 includes a limiting surface 122b. The first turntable 119 includes an arc surface 119a. When the arc surface 119a abuts against the limiting surface 122b, it limits the transmission disc 122. There are four guide grooves 122a and limiting surfaces 122b, which are equidistantly distributed around the circumference of the transmission disc 122. The four guide grooves 122a and limiting surfaces 122b are spaced apart. When it is time to replace the next set of filter screens 112 and filter layers 113, the second rotating shaft 118 is rotated. The rotation of the second rotating shaft 118 drives the first rotating disk 119 to rotate. The first rotating disk 119 drives the drive column 121 to rotate via the connecting block 120. The drive column 121 drives the transmission disk 122 to rotate 90 degrees via the guide groove 122a. The rotation of the transmission disk 122 drives the first rotating shaft 109 to rotate. The rotation of the first rotating shaft 109 drives the adjusting disk 110 to rotate, thereby rotating the adjusting disk 110 by 90 degrees. This allows for the replacement of the next set of filter screens 112 and filter layers 113. The replacement is convenient and does not require the disassembly and replacement of a conventional filter screen 112. After rotating 90 degrees, the drive column 121 disengages from the guide groove 122a and is restricted by the arc surface 119a and the limiting surface 122b to prevent the transmission disk 122 from continuing to rotate.

[0034] The locking element is used to lock the adjusting element. The locking element includes: a guide shaft 123, a baffle 124, a first slip ring 125, a limiting post 126, and a first spring 127. The guide shaft 123 is fixedly connected to the second rotating shaft 118. The baffle 124 is located at one end of the guide shaft 123 and is fixedly connected to the guide shaft 123. The first slip ring 125 is horizontally slidably connected to the guide shaft 123. Specifically, the guide shaft 123 has a first groove 123a extending axially along the guide shaft 123, and the first slip ring 125 is partially located within the first groove 123a and moves along the first groove 123a.

[0035] The limiting post 126 is fixedly connected to the first slip ring 125. The first spring 127 is sleeved on the guide shaft 123, and its two ends are fixedly connected to the baffle 124 and the first slip ring 125, respectively. The second end cover 108 includes a limiting groove 108a, into which the limiting post 126 is inserted to limit the guide shaft 123 and the second rotating shaft 118. One end of the first slip ring 125 is provided with a push plate 128, which facilitates the movement of the first slip ring 125. When adjustment is required, push the push plate 128. The movement of the push plate 128 causes the first slip ring 125 to move, which in turn causes the limiting post 126 to move, disengaging the limiting post 126 from the limiting groove 108a. Then, the first slip ring 125 can be rotated (360 degrees). The rotation of the first slip ring 125 causes the second rotating shaft 118 to rotate, thereby adjusting the position of the adjusting plate 110. After adjustment, release the push plate 128. Under the action of the first spring 127, the first slip ring 125 will reset, allowing the limiting post 126 to insert into the limiting groove 108a and relock the second rotating shaft 118.

[0036] The filter assembly also includes a limiting ring 116 and a limiting disc 117. The limiting ring 116 is fixedly connected to the adjusting disc 110. The limiting disc 117 is rotatably connected to the adjusting disc 110. The limiting ring 116 is located at one end of the adjusting disc 110, and the limiting disc 117 is located at the other end of the adjusting disc 110. The limiting disc 117 includes a limiting hole 117a and a disassembly hole 117b. The diameter of the limiting hole 117a is smaller than the diameter of the filter screen 112, and the diameter of the disassembly hole 117b is larger than the diameter of the filter screen 112. There are four disassembly holes 117b and limiting holes 117a, which are equidistantly distributed along the circumference of the limiting disc 117, and the four disassembly holes 117b and limiting holes 117a are staggered. When the four filter layers 113 and filter elements are used up and need to be replaced, rotate the second end cap 108 to separate it from the first end cap 107, thereby disengaging the adjusting plate 110 from the second end cap 108. Then rotate the limiting plate 117 to rotate the disassembly hole 117b of the limiting plate 117 to a position coaxial with the mounting hole 110a, allowing the filter layers 113 and filter screen 112 to be detached from the disassembly hole 117b for replacement. After replacing the filter layers 113 and filter screen 112, rotate the limiting plate 117 to align the limiting hole 117a of the limiting plate 117 with the mounting hole 110a. A damping block is provided between the limiting plate 117 and the adjusting plate 110, so the limiting plate 117 will not rotate without external force, thus completing the replacement of the filter screen 112 and filter layer 113. The replacement is very convenient.

[0037] Workflow: First, the evaporation tank and the atomization tank are filled with water using pump 105. Then, the water is evaporated using steam generator 102 and atomizer 103. The evaporated and atomized water vapor is mixed by fan 104 and then transported to flue 101a. Pollutant gas is also transported through standard gas inlet 101b and mixed with the water vapor. The high-humidity flue gas containing the target pollutant is discharged from flue 101a. The pollutant concentration is observed by the instrument. After stabilization, monitoring begins from sampling port 101c. Simultaneously, water is replenished to the evaporation tank and the atomization tank using pump 105.

[0038] When it is necessary to replace a set of filter screens 112 and filter layers 113, push the push plate 128. The movement of the push plate 128 causes the first slip ring 125 to move, which in turn causes the limiting post 126 to move, disengaging the limiting post 126 from the limiting groove 108a. Then, the first slip ring 125 can be rotated (360 degrees). The rotation of the first slip ring 125 causes the second rotating shaft 118 to rotate, which in turn causes the first turntable 119 to rotate. The disc 119 drives the drive column 121 to rotate via the connecting block 120. The drive column 121 drives the transmission disc 122 to rotate 90 degrees via the guide groove 122a. The rotation of the transmission disc 122 drives the first rotating shaft 109 to rotate, which in turn drives the adjusting disc 110 to rotate. This allows the adjusting disc 110 to rotate 90 degrees, enabling the replacement of the next set of filter screens 112 and filter layers 113. Replacement is convenient, eliminating the need for disassembly and replacement like with conventional filter screens 112, making it more convenient to use. After rotating 90 degrees, the drive column 121 disengages from the guide groove 122a and is restricted by the arc surface 119a and the limiting surface 122b, preventing the transmission disc 122 from continuing to rotate. This allows the position of the adjusting disc 110 to be adjusted. After adjustment, releasing the push plate causes the first slip ring 125 to reset under the action of the first spring 127, allowing the limiting column 126 to insert into the limiting groove 108a, thus relocking the second rotating shaft 118.

[0039] When the four filter layers 113 and filter elements are used up and need to be replaced, rotate the second end cap 108 to separate it from the first end cap 107, thereby disengaging the adjusting plate 110 from the second end cap 108. Then rotate the limiting plate 117 to rotate the disassembly hole 117b of the limiting plate 117 to a position coaxial with the mounting hole 110a, allowing the filter layers 113 and filter screen 112 to be detached from the disassembly hole 117b for replacement. After replacing the filter layers 113 and filter screen 112, rotate the limiting plate 117 to align the limiting hole 117a of the limiting plate 117 with the mounting hole 110a. A damping block is provided between the limiting plate 117 and the adjusting plate 110, so the limiting plate 117 will not rotate without external force, thus completing the replacement of the filter screen 112 and filter layer 113. The replacement is very convenient.
