[0017] The first filler shell 1 and the grille 3 form a movable installation structure through the lower slot component 4 and the upper slot component 5. The upper and lower connecting ends of the first filler shell 1 and the grille 3 fit each other, including the lower slot component 4 and the upper slot component 5 at the front and rear ends. A groove is provided inside the lower slot component 4 and the upper slot component 5 to facilitate the connection of the clamping ring component 6, so that the first filler shell 1 and the grille 3 can be directly limited vertically.

[0018] The first filler shell 1 forms a disassembly and assembly structure with the second filler shell 2 through the snap ring component 6. When the first filler shell 1 and the second filler shell 2 are respectively fitted with the grille 3, the snap ring component 6 is inserted into the lower slot component 4 and the upper slot component 5 to form a limit, thereby ensuring that each filler unit can be overlapped and fixed.

[0019] The grid 3 is in a diamond-shaped structure as a whole. The diamond-shaped grid 3 has sixteen equidistant vertical bars. The diamond-shaped grid 3 has the advantages of high strength, light weight, low pressure drop, high specific surface area, easy replacement, and recyclability.

[0020] The inner surfaces of the first filler shell 1 and the second filler shell 2 are respectively provided with guide brackets 7 . The guide brackets 7 provided inside the first filler shell 1 and the second filler shell 2 facilitate the guided installation of the inner cavity 8 of the filler unit, thereby reducing the difficulty of installation.

[0021] The inner surface of the guide bracket 7 is a trapezoidal structure, and the guide bracket 7 and the inner cavity 8 are matched with each other. The guide bracket 7 and the inner cavity 8 are movably connected. The first filling shell 1 and the second filling shell 2 are filling units, which are integrally formed by injection molding of polypropylene plastic. The overall structure is centrally symmetrical. The inner cavity 8 is located in the middle of the filling unit, and the cavity surface has holes to ensure close contact with the filler. The first filling shell 1 and the second filling shell 2 are connected by a clamping ring component 6, a lower clamping groove component 4 and an upper clamping groove component 5. The filling unit is fixed on the supporting device, and the supporting device is symmetrically located on the six sides of the hexagonal prism, the side where the long side of the trapezoid of the quadrangular prism is located.
