The reactor has a structure in which a large number of catalysts are integrated in a case.

る。The reactor of the exhaust gas denitration device for a ship needs to be made compact so that it can be accommodated in a narrow space inside the ship. In particular, in a small vessel, there is usually no space for newly installing a denitration reactor inside the hull or on the deck, so the vertical reactor shown in FIG. 7 is used as a makeup chimney (funnel). Will be installed inside.
【０００７】しかしながら、脱硝装置の反応器内に収め
るセラミックのハニカム触媒は強度的に脆く欠けやす
い。さらに反応器の部材と直接接触する場合には振動に
よる摩擦で削られ、擦り減りやすい。However, the ceramic honeycomb catalyst contained in the reactor of the denitration device is fragile in strength and easily chipped. Further, when it comes into direct contact with the members of the reactor, it is scraped by friction due to vibration and is easily worn away.

られなかった。Therefore, in the reactor 100 in which the catalysts are vertically arranged as shown in FIG.
It is easy for accidents that concentrate on the contact area with 02 and damage it. Therefore, this type of reactor was unsuitable for ships and was practically only used on land.

並べて荷重の分散を図ればよい。That is, the equipment mounted on the ship is likely to be subjected to shock vibration due to waves and vibration transmitted from the mounted engine, and therefore it is necessary to have excellent vibration resistance.
Then, in order to improve the vertical vibration resistance of the catalyst, it is sufficient to arrange the catalysts 1 horizontally to disperse the load as in the reactor 200 shown in FIG.

碍となっていた。However, the reactor 200 according to the conventional design concept shown in FIG. 8 has a problem that the space required for installation is too large. The width dimension thereof is the dimension a in the longitudinal direction of the catalyst 1 and the catalyst 1 for guiding the exhaust gas.
Is the total (a + b + b) of the dimensions b and b of the space inside the case 201 provided at both ends in the longitudinal direction of the. This large size was difficult to secure in a ship with no wasted space. This has been a hindrance to practical use of a horizontal reactor in which the longitudinal direction of the catalyst is aligned with the horizontal direction.

It is characterized in that the catalysts are stacked so that the positions thereof are sequentially displaced in the same direction, and the catalysts are arranged so that the longitudinal direction of the catalysts and the traveling direction of the ship are at right angles.

く、反応器内の両端に設けるスペースが節約できる。The catalyst has sufficient vibration resistance with respect to vertical vibration acceleration that is received when the hull is pitched. In addition, since the catalysts are stacked with their positions gradually shifted in the longitudinal direction, it is easy to uniformly guide the exhaust gas to the catalysts, and the space provided at both ends in the reactor can be saved.

The catalyst 1 used in the first embodiment of the present invention is the same as that used conventionally. As shown in FIGS. 1 and 2, the case 3 of the reactor 2 includes a lower part 4 having an exhaust gas inlet 6 on the lower surface side.
And an upper part 5 having the outlet 7 on the side of the upper surface.

A plurality of catalysts 1 in a single stage (five in the figure) are stacked in a plurality of stages (five in the figure). In each stage, the catalysts 1 are arranged with their end faces aligned with the traveling direction A so that the longitudinal direction thereof is orthogonal to the traveling direction A of the ship. In other words, each catalyst 1 is arranged so that its longitudinal direction coincides with the lateral direction B (rolling direction) of the ship.

Therefore, if the ceramic felt 12 shown in FIGS. 4 and 5 is omitted, the catalyst stacking height h at this time is 150 mm × 5 steps = when the dimension of one side of the prismatic catalyst is 150 mm.
It is in the range of 750 mm to 150 mm × 7 steps = 1050 mm.

The position of the lowermost catalyst 1 in the upper part 5 is the same as the position of the uppermost catalyst 1 in the lower part 4. The catalyst 1 in the upper part 5 is the catalyst 1 in the uppermost stage.
So that it comes to the same position as the lowermost catalyst 1 in the lower part,
Each stage is stacked while shifting the position by a predetermined size.

The support grid 8 is formed by integrating a plurality of holding plates 9 each having a size and shape matching the end surface of the catalyst 1 with a substrate 10 and a connecting rod 11, which are turned upside down to form a pair of both ends of the catalyst 1 at each stage.

The function of the ceramic felt 12 is to cushion the assembly of adjacent or stacked catalysts 1 when impacted. It also has a function of sealing the space between the adjacent catalysts 1 and 1 so that the exhaust gas introduced into the case 3 can be surely passed through the catalyst 1. In addition, the neighbor's catalyst 1,
It prevents the 1 from breaking due to direct contact.
In this embodiment, the upper and lower catalysts 1 and 1 are slightly displaced from each other in the longitudinal direction.
The sticking position of is also shifted accordingly.

It is divided into a space S3 following. And the spaces S1 and S3

Since the length of the catalyst 1 is the same as that of c, the width of the reactor 2 of this example is a + b + c. Here, in the reactor 2 of this embodiment, the catalyst 1 is stacked in a staggered manner, so that the dimension c can be made considerably smaller than the dimension b. The dimension C is such that one side of the prismatic catalyst is 14
Since it is 0 mm to 160 mm, C = 180 mm to 240
mm is sufficient. Width dimension of this reactor 2 a + b +
c <the conventional width dimension a + 2b, and the reactor 2 of the present embodiment can be installed in a narrower space than the conventional one.

If it is 40% or more, the catalyst in the lower product is easily broken due to the influence of local load concentration.

ことができる。As for the arrangement of the catalysts, the longitudinal positions of the catalysts are sequentially displaced in the same direction, so that the catalysts can be prevented from being scraped by friction between them. Further, since the traveling direction of the ship and the longitudinal direction of the catalyst are arranged at a right angle, the load applied to each catalyst 1 is dispersed, and especially for the vertical vibration acceleration of 1 to 2 G during pitching, The reactor 2 of this example has sufficient vibration resistance. Further, the displacement of the catalyst in the longitudinal direction due to the rolling of the ship can be suppressed by the support grids 8 at the left and right ends.

The inflow of exhaust gas into each catalyst 1 of the
