Supporting Device Metal Grating FillingThe basic requirements are: sufficient strength to support the weight of the filling material; adequate free cross-section to minimize the flow resistance of both gas and liquid phases; conducive to liquid redistribution; good performance; ease of manufacturing with various materials; and ease of installation and disassembly.

Supporting Device Metal Grating FillingIt is a simple and commonly used packing support device. It is placed on the support ring that is welded on. Cast iron support grating has been long applied in the chlor-alkali industry and sulfuric acid industry. However, when filling loose packed packing, large-sized cross-shaped spacer rings can be neatly arranged on the grating bars, with the size specifications depending on the packing model inside the tower.
