本発明はガス水平流型反応器に装填する触媒ブロックに
関し、特に外枠構造を改善した上記触媒ブロックに関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a catalyst block to be loaded into a gas horizontal flow reactor, and more particularly to the above-mentioned catalyst block having an improved outer frame structure.

のである。As shown in Fig. 1, a conventional gas horizontal flow type denitrification reactor is a reactor in which a plurality of catalyst units 1 each having a large number of plate-shaped catalysts are held in a grid-shaped outer frame 2 to form a block. A gas flow G is passed through the reactor to carry out a predetermined reaction.

ックを提供することにある。By blocking the catalyst unit in this way,
In addition to improving the workability of catalyst filling on-site,
This makes it possible to form a compact catalyst layer. However, when the catalyst block is formed using the conventional lattice-shaped outer frame 2, since the outer frame is a fabricated product, fabrication tolerances are required.For example, as shown in FIG. 1, and there are gaps around each catalyst unit 1 due to canning tolerances, that is, a dimensional difference ΔH between the height direction of the outer frame and the height direction of the catalyst unit, and a dimensional difference ΔH between the width direction of the outer frame and the catalyst unit. A dimensional difference ΔB in the width direction occurs. If such a gap ΔH)ΔB exists, there is a drawback that some gas passes through the gap and flows out without passing through the catalyst layer. Therefore, in order to obtain a good catalyst layer, it is necessary to seal the gap ΔH9ΔB between the outer frame and the catalyst unit so that all the gas passes through the catalyst surface. Therefore, in the conventional technology, as shown in Fig. 4,
A method such as inserting a seal plate 3 into the gap ΔB created between the lattice-shaped outer frame 2 and the catalyst unit 1 was proposed.
SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the prior art described above and to provide a catalyst block having a structure that does not create a gap between the outer frame and the catalyst unit.

This is what I did. The present invention will be explained in more detail below with reference to the drawings.

。This catalyst block has catalyst units 1 filled in a lattice-shaped outer frame 4 made of a steel plate formed into a V-shaped cross section by press working. This outer frame 4 connects a plurality of frame bodies 4A in the gas flow direction to a lattice-shaped outer frame 4A having protrusions with a V-shaped cross section provided at intervals of the catalyst units 1 in the gas flow direction. It consists of an L-shaped member 4B. The frame body 4A has a spacing 12 between the protrusions of the frame body 4A that is smaller than the length 11 of the catalyst unit so that the corner portion of the catalyst unit 1 comes into contact with the inclined surface of the V-shaped protrusion of the frame body 4A. haze) is arranged so that it is short. To load the catalyst units 1 into such an outer frame 4, after stacking the catalyst units 1 inside the outer frame 4, as shown in FIG. All you have to do is press it down with force and fix it to the frames on both sides. The joints between the upper and lower frames 4A and the side frames 4A are shaped to match the corner portions of the catalyst unit, as shown in FIG. If the catalyst block is configured as described above, the horizontal component P2 of the force P1 that presses the catalyst unit 1 acts as shown by the arrow as shown in FIG.
It is pressed against the ■-shaped inclined part of A, thereby completely closing the gaps ΔH and ΔB caused by the manufacturing tolerance.

Next, Fig. 9 shows a case in which protrusions with a V-shaped cross section are provided on all four sides of the inner periphery of the frame 4A, but compared to the embodiment shown in Fig. 8, protrusions are also provided on the lower surface. So,
The catalyst layer can be sealed more evenly.

At the same time, the gaps ΔH and ΔB caused by canning tolerances are also gathered around the periphery as shown in the figure, and these gaps are closed by the ridges of the frame 4A. can be blocked. Therefore, the conventional seal plate (FIG. 4) is no longer necessary. In the above embodiment, the protruding portion of the frame 4A has a cross-sectional shape of ■, but it may have any other shape such as a U-shape or a semicircle as long as it can seal the catalyst block.
