[0045] See also Figure 3 and Figure 5 The first tray 200 is disc-shaped, and the size of the first tray 200 matches the diameter of the inner cavity of the filter tank 100. The outer edge of the first tray 200 is arranged on a fence for limiting the filter element 300 to prevent the filter element 300 from shifting on the first tray 200, so as to facilitate the movement of the filter element 300 with the first tray 200.

[0046] In some embodiments, the first hollow pattern is used for allowing the mixed gas to pass through, and the first hollow pattern can be a plurality of circular holes. Of course, the cross section of the first hollow pattern can also be other shapes, such as diamond and square.

[0047] In some of the embodiments, the first tray 200 is hinged to the outer circumferential wall of the filter tank 100 via a hinge 800 . The hinge 800 has a simple structure and is easy to use.

[0048] See also Figure 4 and Figure 5 An arc portion is provided on the outer side of the fence of the first tray 200.

The mesh plates 512 are located below the spray nozzle, and the spray nozzle sprays the liquid medicine onto the mesh plates 512. The liquid medicine forms a water film on the mesh plates 512. When the mixed gas is transported from bottom to top, the contact area between the mixed gas and the water film is large enough, and the sulfur in the mixed gas fully reacts with the liquid medicine, thereby removing the sulfur in the mixed gas as much as possible.
