Round steel, outer ring band steel are higher than internal band steel, and Johnson Net welding is arranged within band steel circle, and main grate cannot be using stiffened panel
Mode is reinforced, therefore using the reinforcement measure for interting round steel among flat steel bar, the band steel circle of periphery is than internal flat steel bar
It is higher by certain size, the size being higher by is equal to the thickness of Johnson Net.
Further preferred, the band steel that the rib of the Johnson Net is supported with main grate is mutually perpendicular to, Johnson Net
Rib and the flat steel bar of grid be mutually perpendicular to, intersection spot welding is fixed, rib and net both ends all with the band steel circle of grid
Spot welding is fixed, so that sound construction, bearing capacity is stronger, is hardly damaged.
Further preferably the top of the Johnson Net is additionally provided with pressing device, and pressing device includes being fixed on
Support plate on the inner wall of reactor outline border is provided through hold-down bolt in support plate, and hold-down bolt bottom is provided with pressing plate,
Johnson Net is arranged in close to the top of reactor outline border inner wall in pressing plate, the bracing ring that can be pressed on Johnson Net in reactor
In supporting beam.
The beneficial effects of the utility model are:
(1) alkylation reactor catalyst bed support construction described in the utility model, Johnson Net and main grate branch
Support is welded and fixed connection, and Johnson Net obtains the reinforcing that main grate supports, and solves that Johnson Net is easy to damage and easily-deformable to ask
Topic；
(2) alkylation reactor catalyst bed support construction described in the utility model, distribution grid are separated with main grate,
After solving Johnson Net and the fixation of main grate supporting welding, the back side is difficult to the problem of clearing up；
(3) alkylation reactor catalyst bed support construction described in the utility model, setting auxiliary lattice under distribution grid
Grid support, not only increases the rigidity of distribution grid, also distribution grid is avoided directly to contact with support ring and backbar, so that on distribution grid
Distribution hole can be evenly arranged in entire reactor cross section.
