Embodiment 1
[0020] Φ25mm ceramic foam annular filler is used, the ceramic foam aperture of the torus (1) is 2mm, the diameter of the inner cavity (2) is 10mm, the packing height is 7.5mm, the ratio of height to diameter is 0.3, and the ratio of inner and outer diameters is 0.4.
[0021] Such as figure 1 , figure 2 As shown, the torus (1) of the ceramic foam ring packing is made of foam ceramics and has a unique three-dimensional network structure, which is similar to the structural characteristics of the composite expanded mesh packing. These small holes communicate with the packing surface and have a large specific surface area. Bulk density is small.
[0022] The middle of the packing structure is a cylindrical cavity (2). Such an open packing structure is conducive to further increasing the void ratio of the packing, reducing flow resistance, and at the same time facilitating the renewal of the packing surface and improving the mass transfer efficiency.
[0023] The packing structur...
Embodiment 2
[0034] Adopt Φ50mm ceramic foam annular filler, the ceramic foam aperture of the torus (1) is 5mm, the diameter of the inner cavity (2) is 30mm, the packing height is 20mm, the ratio of height to diameter is 0.4, and the ratio of inner and outer diameters is 0.6.
[0035] The porosity of the ceramic foam filler of the present invention is as high as 94%, which is higher than that of Pall rings and saddle rings of the same material, and the specific surface area is 2156m 2 / m 3 , bulk density is only 204kg / m 3. The fluid resistance (i.e. the pressure drop of the packing layer) of the ceramic foam packing of the present invention is less than several other packings of the same size, which is 54% to 67% of the ceramic Pall ring and the saddle ring, and is 54% to 67% of the stainless steel Pall ring and the saddle ring. 67-75%, which indicates that the energy consumption of fluid passing through the packing layer is reduced. Compared with the Pall ring and the saddle ring, the ...
Embodiment 3
[0037] Φ50mm ceramic foam ring packing, the ring body (1) has a ceramic foam hole diameter of 4mm, the internal cavity (2) has a diameter of 40mm, a packing height of 30mm, a ratio of height to diameter of 0.6, and a ratio of inner and outer diameters of 0.8.
[0038] The porosity of the ceramic foam filler of the present invention is 94%, which is higher than the Pall ring and saddle ring of the same material, and the specific surface area is 2016m 2 / m 3 , bulk density is only 195kg / m 3 . The fluid resistance (i.e. the pressure drop of the packing layer) of the ceramic foam filler of the present invention is less than several other fillers of the same size, which is 52% to 68% of the ceramic Pall ring and the saddle ring, and 52% to 68% of the stainless steel Pall ring and the saddle ring. 71-85%, which indicates that the energy consumption of fluid passing through the packing layer is reduced. Compared with the Pall ring and the moment saddle ring, the mass transfer unit...
