Due to the inherent structural characteristics of structured packing, the supporting device used is simple in structure. The corrugated structured packing supports the grid, and the grid bar spacing is 50~100mm. The lower end of the grid bar is serrated so that the liquid flows down evenly from the tooth tip. For small towers (generally less than 1m in diameter) with flanged cylinders, an integral structure can be made. It is made of 3~10mm thick flat steel, with a grid plate ring and grid bars 50~100mm high, placed on a support ring welded in the tower wall or 4~8 supports evenly distributed along the periphery. The above dimensions are determined by the weight of the packing supported by the grid plate.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

For integral towers with manholes, the supporting grid can be made into a block structure. The width of each block is determined by the size of the manhole. If the tower diameter exceeds 2m, an intermediate supporting beam should be added; if the tower diameter is larger, multiple supporting beams should be added.<\/p>

The supporting beam is generally made of I-beam, and the supporting grid is placed on it, and the surrounding is also placed on the tower wall support ring. The tower wall may also be provided with no support ring. In this case, the supporting grid should be fixed to the supporting beam to prevent the supporting grid from falling and causing an accident. For towers with extra-large diameters, a truss structure can be used instead of a supporting beam, which is conducive to the distribution of gas and liquid.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

In the large diameter tower, the support grating needs to be supported by beams, which are generally made of I-beams, which causes local resistance to gas-liquid flow and affects the uniform distribution of gas. Moreover, the large size of the I-beam also occupies the space of the tower, in order to reduce resistance, save materials and facilitate gas-liquid distribution, we have developed a grid beam-type support device, which is made of thick steel plate (5 ~ 10mm). It is made of thick steel plate (5~10mm). The height is determined by the load capacity (100~200mm), and the number of bars in each beam is 5~10, the spacing of bars is 50~100mm, and the bars are reinforced with fixed-pitch plates. Grid beams are fixed on the support welded to the tower wall. There is a connecting plate between the beams, and the conventional block grating is placed on the connecting plate to form a complete supporting grating. The section coefficient of the grating beam is large, so when the weight of the material used is the same, its strength and stiffness are larger than the I-beam, and the grating spacing design is the same as the spacing of the conventional grating plate, so the resistance is small and the gas-liquid distribution is uniform. Jihua Nitrogen Fertilizer Plant in the methanol tower used in the evening 2600, the effect is very good.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The corrugated filler beam type support device is basically the same as the grid beam support device. It is a corrugated filler beam assembled by plug welding of 70~125V plate corrugated filler pressed from a metal plate with a thickness of 6~10mm and a height of 100~200mm to replace the grid beam in the grid beam support device. The same type of filler is placed on the connecting bars between the two corrugated filler beams, and its structure is the same as the grid beam. In this way, the support beam and the filler form a complete filler tray. Since it saves the I-beam support beam of the general filler and has a higher section coefficient, it saves the space and metal materials of the tower. At the same time, the beam composed of the corrugated filler has the function of mass transfer and gas distribution.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
