があった。As shown in FIG. 2, this catalyst unit 3 has a large number of plate-shaped catalysts 5 arranged in parallel inside a box 4 so as to be parallel to the gas flow IA. In order to install such a gas horizontal flow type denitrification equipment, a third
As shown in the figure, a method is adopted in which several catalyst units 3 are held in a lattice-shaped outer frame 2 and set inside a denitrification reactor (duct) 1. Inside the duct (denitrification reactor) 1, the catalysts are stacked as shown in Figure 1, so a lattice-shaped outer frame 2 at the bottom is used as an outer frame that holds the catalyst units 3 stacked on top of it. It must have enough strength to withstand the weight of the frame 2. In addition, the outer frame 2 is
It is desirable to have a shape that reduces the dead space created by the outer frame member for the passing gas and does not reduce the effective area of the catalyst. Conventionally, a lattice-shaped outer frame made of flat plates as shown in Figures 3 and 4 was used as an outer frame, but because the strength was 4 mm, flat plates had to be assembled inside the outer frame in a lattice shape. However, the drawback was that it was difficult to work with.

解消し、構造および工作が簡単で、しかもデッドスペー
スが小さい触媒ユニット外枠を提供することにある。For this reason, a box-shaped outer frame 6 using square pipes as outer frame members has been proposed as shown in FIG. The dead space occupied in the reactor increases, resulting in a disadvantage that the ratio of the cross-sectional area through which the gas passes to the cross-section of the reactor decreases. SUMMARY OF THE INVENTION An object of the present invention is to provide a catalyst unit outer frame which is simple in structure and work, and has a small dead space, by eliminating the drawbacks of the above-mentioned follower technology.

性能を向上させたものである。The present invention provides an outer frame for a plurality of catalyst units disposed in a gas horizontal flow reactor as an outer frame for holding catalyst units, in which a longitudinal center portion has a V-shaped cross section as a constituent member of the outer frame. By using two or more pressed steel plates in a direction perpendicular to the gas flow and in such a way that the rectangular catalyst unit is held between the V-shaped protrusions, it is possible to Eliminating the existing lattice structure,
In addition, the dead space caused by the outer frame is minimized and cross-sectional performance is improved.
以下、本発明の触媒ユニット外枠を図面によりさらに詳

することができる。In the figure, the longitudinal center of the outer frame 1 that holds the catalyst unit 3 is made of a steel plate that is pressed into a V-shaped cross section. The press bending angle Q (Fig. 8) of the above steel plate is 4
It is 5 degrees or less, preferably about 30 to 35 degrees. By providing this press bent part, the strength and rigidity of the outer frame are increased, and the exhaust gas flows smoothly along the outer frame as shown by the arrow (Figure 8), reducing dead space and pressure loss. Occurrence is prevented. Further, the bent portion securely fixes the catalyst unit, and can also be used as a spacer for the row of catalyst units. As described above, according to the present invention, by using a pressed slope member as the outer frame that holds the catalyst unit, the structure of the outer frame can be simplified and the dead space caused by the outer frame inside the reactor can be minimized. I can do it.
