Abstract

A catalyst support disc comprises a support beam fixed on a cylinder wall of a reactor. The support beam is in the shape of an inverted T; the bottom end of the support beam forms a support table; a plurality of cross beams vertical to the support beam are arranged on the support table of the support beam; both ends of each cross beam are welded on connecting beams which are mounted on the support table; support bars vertical to the cross beams are uniformly arranged on the cross beams at intervals; and metal grid bars vertical to the support bars are uniformly fixed on the support bars at intervals. The catalyst support disc has the advantages of simple structure, convenient installation, little possibility of deformation at high temperature and the like. If being mounted in a catalytic hydrogenation reactor, the catalyst support disc can realize support to catalyst bed and distribution of fluid at the same time. In addition, the service life of the catalyst support disc is 1 to 1.5 times of that of an ordinary support disc.

Description

The catalyst supporting disk

Technical field

The utility model relates to a kind of internals of petroleum refining reactor, especially relates to a kind of catalyst supporting disk that plays support, fixed catalyst bed in reactor.

Background technology

At present in petroleum chemical industry, for yield and the product quality that improves light oil, often need the product of crude oil fractions gained is carried out catalytic hydrogenation (for example hydrocracking and hydrofinishing), further refine, feedstock oil under catalyst action, is finished a series of reaction in reactor.Use at present at reactor, a plurality of beds are generally all arranged, need corresponding supporting disk and hold whole beds, and supporting disk not only plays the effect of supporting whole beds, distribution that also can convection cell exerts an influence, mobile and the pressure that can influence fluid as supporting disk top sieve mesh falls, the precision of mesh can influence the extent of damage of catalyst granules, expansion along with industry size, the scale of reactor is also increasing, its diameter also comes greatly more, requirement to the catalyst supporting disk is also more and more higher, but the supporting disk that uses exists complexity is installed at present, be not easy to field-strip, even dismounting once or often need to change whole supporting disk when having part to damage, the yielding problems such as catalyst leakage that cause under the high temperature.

Summary of the invention

The utility model mainly be solve existing catalyst supports take inventory the installation complexity, be not easy to dismounting and maintenance, problem such as yielding under the high temperature.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: this catalyst supporting disk, comprise the backbar that is fixed on the reactor barrel, described backbar is an inverted T-shape, its bottom constitutes a saddle, on the backbar saddle, be provided with many crossbeams perpendicular to backbar, all crossbeam two ends all are welded on the tie-beam, and tie-beam is installed on the saddle, be provided with support bar on the described crossbeam uniformly and equidistantly, be fixed with metal grizzly bar on the described support bar uniformly and equidistantly perpendicular to support bar perpendicular to crossbeam.

As preferably, the cross section of described metal grizzly bar is a del, and the top corner part of its del is welded on the support bar.

Therefore, the utlity model has simple in structure, easy for installation, advantage such as not yielding under the high temperature, the utility model is installed in the catalytic hydrogenation reaction device, can satisfies support and fluid distribution simultaneously, and be 1～1.5 times of common supporting disk service life beds.

The specific embodiment

Fig. 1 is a kind of preferred implementation structural representation of the utility model, and Fig. 2 is the vertical view of enforcement shown in Figure 1, and Fig. 3 is an A shown in Figure 1 place partial enlarged drawing; Fig. 4 is a B shown in Figure 1 place partial enlarged drawing; In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be known, the utility model mainly is made up of backbar 2, crossbeam 5, connection strap 4, support strip 6, metal grizzly bar 7, pottery towline 3 etc.

The two ends of the backbar 2 of T type are fixed on the boss of wall of reactor 1, its bottom constitutes a saddle 21, saddle 21 is provided with many crossbeams 5 perpendicular to backbar, all crossbeam 5 two ends all are welded on the tie-beam 4, and tie-beam 4 is installed on the saddle 21, on crossbeam 5, be provided with support bar 6 uniformly and equidistantly, and be fixed with metal grizzly bar 7 on the support bar 6 uniformly and equidistantly perpendicular to support bar 6 perpendicular to crossbeam.According between two backbars 2 or the card shape between backbar 2 and the wall of reactor 1, described tie-beam 4, crossbeam 5, support strip 6 and metal grizzly bar 7 can be made into integral module; During installation, all integral module assembly units are got up just can be combined into the supporting disk card.For enhanced leaktightness, the slit in each module between tie-beam 4 and brace summer 2 or the wall of reactor 1 is provided with pottery towline 3.

Fig. 5 is a C shown in Figure 2 place partial enlarged drawing, and Fig. 6 is the sectional view of the metal grizzly bar of embodiment shown in Figure 5.By Fig. 5 in conjunction with Fig. 6 further as can be known, the cross section of metal grizzly bar 7 is a del, and the top corner part of its del is welded on the support bar.

At the metal grizzly bar support strip 6 and crossbeam 5 are set for 7 times and can play supporting metal grizzly bar 7, make metal grizzly bar 7 can bear bigger weight and hold beds and unlikely distortion, gap between the metal grizzly bar 7 can be satisfied the needs that fluid flows again simultaneously, so the utlity model has great bearing capacity and filter effect.

Between tie-beam 4 and brace summer 2 or the wall of reactor 1 pottery towline 3 is set, can play the effect of sealing on the one hand, prevent to let out the gap of catalyst between tie-beam 4 and backbar 2 or wall of reactor 1, avoid simultaneously owing to expand with heat and contract with cold effect connection strap 4 with remove to support beam 2 or wall of reactor 1 between mutual extrusion supporting disk produce to be out of shape damage, thereby prolonged its service life.

Adopt tie-beam 4, crossbeam 5, support strip 6 and metal grizzly bar 7 to form the structure of a plurality of integral modules, make the utility model install simply, and after certain part of supporting disk is damaged, only need corresponding module replacing is got final product, need not whole supporting disk is all changed, to economize on resources.
