Description

Filler supporting beam and nonmetal tower supporting structure

Technical Field

The utility model belongs to the technical field of chemical industry equipment, in particular to filler supporting beam and non-metallic tower ware bearing structure.

Background

In a chemical production system, a lot of strong corrosion media can resist corrosion only by non-metallic materials, such as acid, saline water, chlorine water and other media with higher concentration, and non-metallic packed towers of PVC, FRP, PTFE and the like are widely applied to the chemical production system. The structure commonly applied to the packing support of the non-metal tower in the prior art is as follows: as shown in fig. 1 and 2, the upper part is provided with a non-metal grid plate strip 4, the circumference of the tower is provided with a circle of supporting ring plates 6, and the upper surface of each supporting ring plate is flush with the lower surface of the sieve plate; the lower surface of the supporting ring plate 6 is evenly provided with supporting ribs 3, the lower part of the non-metal grid plate strip 4 is provided with a plurality of supporting beams 5, two ends of each supporting beam 5 are provided with supporting seats 14, each supporting beam 5 is a non-metal beam or a corrosion-resistant non-ferrous metal beam, two ends of each supporting beam 5 are placed on the supporting seats 14, and two ends of each supporting beam 5 are fixed on the supporting seats 14 through U-shaped bolts 15.

Because of the strong corrosivity in the interior of non-metallic equipment, the interior of the non-metallic equipment can only use non-metallic materials which are the same as or similar to the shell or non-ferrous metals with strong corrosion resistance as the interior support, and the non-metallic materials of PVC, FRP and PTFE have low strength and rigidity and poor bearing force which are only one tenth to one twentieth of those of metallic materials. With the upsizing of modern devices, large non-metallic towers are more and more common, often having packing sections up to several meters long, if the weight of the liquid is added, the total weight of some heavy packing will be up to several tens tons, and non-metallic support beams will not be suitable for carrying the packing. Under the same total amount of the filler, the non-metal supporting beam can stably support the filler only by the bending modulus which is tens of times higher than that of the metal supporting beam, and because the supporting sectional area is large, the ventilation rate of the filler section is influenced, and the heat and mass transfer effects are reduced. And the non-ferrous metal also greatly improves the manufacturing cost and reduces the economic benefit because of the high price.

In addition, because of a supporting beam places on the supporting seat, the supporting seat is generally through the welding or winding cladding between nonmetal with the being connected of non-metal tower ware, and the supporting seat has born the weight of most filler almost, and the junction contact surface of supporting seat and tower body is little, and only with equipment internal surface connection, and local stress is big, and the junction is very easy to lose efficacy even causes the destruction of tower body. Like FRP tower inside lining PVC, PVC is the anticorrosive coating, and FRP is the intensity layer, and supporting seat material PVC welds with inside liner PVC, when the bracing beam bears great load and transmits for the supporting seat, can arouse that the PVC inside liner peels off the destruction, and the filler collapses to cause whole tower inefficacy.
