2020 Stainless Steel Vee Wire Wedge Johnson bottom filter

The catalyst support plate is composed of T-shaped girder, grid and wire mesh. Both sides of the girder are placed on the boss of the reactor wall, while the grid is placed on the girder and boss. A layer of thick stainless steel wire mesh and a layer of fine stainless steel wire mesh are laid on the grid, which can be filled with magnetic balls and catalysts. Catalyst support girder and grid should have enough high temperature strength and stiffness. In other words, the bending deformation is very small at 420 (high temperature), and it has certain corrosion resistance. Therefore, the material of girder, grille and wire mesh is stainless steel. In the design, the weight of catalyst and magnetic ball on the catalyst support plate, the weight of catalyst support plate itself, the pressure drop of bed and the weight of operating liquid should be considered in the design, and the structure size of support beam and grid should be obtained through calculation.
