Hump support is used for supporting granular fillers. Hump support is installed at the bottom of the packing layer and is the most widely used tower support. It is widely used in fields such as oil refining, chemical industry, fertilizer, ethylene, and oxygen production.

(1) Good rigidity, allowing for large loads.
(2) Has excellent fluid dynamics performance.
(3) The weight of the packing bed layer under supporting operation conditions
(4) Filler particles or fragments are not easily clogged at the orifice, for sizes smaller than Φ A layer of 300mm high large filler can be placed on the support plate first, and then small fillers can be stacked.
(5) Lightweight and material saving. It can be made of materials such as metal, plastic, ceramics, graphite, etc.
(6) The unit combination structure facilitates installation from the manhole.
(7) The support plate of its three-dimensional structure is conducive to increasing the opening area, making the opening area mostly around 99%. The principle of opening area is that the opening rate must be greater than the porosity of the filling layer, otherwise the support plate forms a "bottleneck" area, which reduces the tower load. The opening area is related to the structure, material, and tower diameter, generally accounting for 70% -99.9% of the tower section. For metal support plates, it should be around 99%.
Hump support is currently a high-performance and widely used tower support for granular fillers, widely used in fields such as oil refining, chemical industry, fertilizer, ethylene, and oxygen production, with a diameter of over 10 meters.
