Description

A support structure for a sulfur reactor

technical field

The utility model relates to a reactor, in particular to a supporting structure for a sulfur reactor.

Background technique

In the existing sulfur recovery reactor, the support of the catalyst generally adopts the structure shown in Figure 3, and a plurality of ribs 3' exposed to the reactor lining 2' are evenly distributed along the circumference of the inner wall 1' of the reactor. A support plate 4' is placed on the plurality of ribs 3', and the grid 5' is placed on the support plate 4' again, and a silk screen (not shown) is laid on the grid 5' simultaneously to prevent catalyst Fall into the grate. And in order to prevent the grid from shaking, the baffle plate 6 ' that is positioned at the grid outside is also fixed on the support plate. Adopting such a support structure can also play the role of supporting the catalyst, but because the support structure directly adopts the grid to support the weight of the catalyst, it can only be applied to small-diameter equipment. With the large-scale development of equipment, if the above-mentioned support structure is still used to fill the catalyst, the area of the grid will be large at this time, and the grid with a larger area will be easily deformed after being stressed, that is, its flatness cannot be achieved. It is guaranteed, and it is also very inconvenient to make and install such a grille. At the same time, since the wire mesh is directly laid on the grid without other treatment on the periphery, catalyst leakage often occurs at the edge of the wire mesh.

Utility model content

The technical problem to be solved by the utility model is to provide a support structure for a sulfur reactor that can make the grid not easy to deform and prevent the catalyst from leaking, aiming at the current state of the prior art.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: the support structure for the sulfur reactor includes a support plate, a grid and a wire mesh laid on the grid, on the support plate is fixed a The outer baffle is characterized in that a support beam with both ends fixed on the inner wall of the reactor through a connecting plate is provided under the grid, the supporting plate is ring-shaped, and the supporting plate is fixed on the connecting plate, The grid is spliced by a plurality of small grids, and each small grid is supported on the corresponding support beam and support plate, and at the same time, a fastener for fixing the wire mesh is arranged on the baffle plate, The edge of the wire mesh extends into the inner lining of the reactor and is fastened in the inner lining of the reactor.

The fasteners in the above scheme can be any one of the prior art. Preferably, the fasteners include studs welded and fixed on the baffle, and the studs are threaded with the first A nut and a second nut located above the first nut, the wire mesh is sheathed on the stud and clamped between the first nut and the second nut.

In order to ensure connection strength and connection stability, a washer may be set on the stud between the wire mesh and the first nut, and a pressure plate may be set on the stud between the wire mesh and the second nut.

The edges of the wire mesh can be connected with anchor nails through iron wires, and the anchor nails are embedded in the lining of the reactor. This structure further fixes the wire mesh, preventing the wire mesh from being disconnected from the inner lining under the misoperation of external force.

Compared with the prior art, the utility model sets the support beam in the reactor and supports the fixed grid through the support beam and the support plate. After the catalyst is loaded, the grid is not easily deformed; at the same time, the grid is divided into There are many small grids, and the flatness of the grid is good; the design of the baffle effectively prevents the series movement of each small grid; and the fixing method of the wire mesh also solves the leakage problem of the catalyst at the edge of the wire mesh in the prior art . The supporting structure for the sulfur reactor is especially suitable for supporting large-scale sulfur reactors.
