Detailed Description
In order to facilitate the technical solutions of the present invention to be understood by those skilled in the art, the technical solutions of the present invention will be further described with reference to the accompanying drawings of the specification
In a marine engine exhaust system, a catalyst is filled in an SCR reaction chamber, and exhaust gas and urea (NH3) are accelerated to react under the catalysis of the catalyst, so that the efficiency of exhaust gas treatment is improved, and the exhaust gas treatment degree is also ensured. TiO is generally selected as the catalyst in the SCR reaction chamber2V as a base carrier2O5And WoO3The mixture, and ultimately the catalyst, is generally present in a regular shape and defined volume, e.g., in the shape of a cylinder, a cuboid, a polygonal prism, etc. Then with TiO2The catalyst and the like which are used as the carrier are easy to break, collapse and the like in work, so that the surface area of the catalyst contacted with the tail gas to be treated is reduced, the catalytic efficiency of the catalyst is reduced, and the tail gas cannot meet the emission requirement.
In order to solve the problems, a shell is generally added outside a catalyst with a regular shape, so that the catalyst is packaged and fixed, a catalyst module is obtained, the problems of breakage and the like of the catalyst in work are effectively solved, the contact area of the catalyst and tail gas is ensured, and the treatment efficiency and the conversion rate of the tail gas are ensured.
The welding tool provided by the invention aims to solve the packaging problem of the catalyst in a cuboid shape. A plurality of rectangular catalysts are combined into a larger rectangular catalyst module for a ship, so that the catalyst module is convenient to arrange, install and fix in a reaction chamber. Generally, when a catalyst module is packaged, two L-shaped housings are buckled with each other, so that a plurality of rectangular catalyst bodies are fixed between the two L-shaped housings. During packaging, the backing plates 12 made of ceramic fiber materials are required to be placed between the catalysts and the shell and between two adjacent catalysts, and certain pressure is required to be applied to the catalysts, the shell and the like during welding, so that gaps between the catalysts and the shell and between the two catalysts are eliminated as much as possible, and the influence on tail gas reaction caused by the fact that tail gas to be treated passes through the gaps is avoided.
When the catalyst module is packaged, the two L-shaped shells are difficult to butt, certain pressure needs to be applied to the shells and the catalyst, and the force application point is difficult to master.
As shown in fig. 1 to 3, the welding tool for encapsulating a marine catalyst module according to the technical solution of the present invention includes two positioning mechanisms 100 disposed opposite to each other, and the catalyst module 10 is positioned by the two positioning mechanisms 100. Positioning mechanism 100 includes unable adjustment base 1 and sets firmly the locating rack on unable adjustment base 1, the locating rack includes that two are the slope form to be fixed unable adjustment base is last to support swash plate 2, and two support swash plates 2 enclose into the support area of a 90 contained angles, and catalyst module 10 is placed support area, two positioning mechanism 100's support area sets up relatively, realizes catalyst module 10 location.
Based on the technical scheme, the specific placing process comprises the following steps: firstly, the lower positioning mechanism 100 is fixed and placed, then the housing 11 of an L-shaped catalyst module is placed in the support area, so that two surfaces of the housing 11 respectively lean against the two inclined support plates 2, i.e. the housing 11 of the catalyst module is fixed firstly. Then, a mat 12 is placed on the inner side of the housing 11 of the catalyst module, respectively. Then, placing a cuboid catalyst; and then the mat 12 between two adjacent catalysts in the catalyst module. Then the rest of the catalyst is well placed. Finally, another L-shaped shell of the upper catalyst module is placed. After the catalyst module is placed, the positioning framework 100 is erected on the catalyst module. Through the special structure of the support area, the two positioning structures 100 can realize the fixation of the whole catalyst module, which is convenient for the mutual welding of the two L-shaped housings on the catalyst module, i.e. the welding at the position of the welding seam 13 in fig. 1.
In the above technical solution, because the two positioning mechanisms 100 realize the positioning of the catalyst module, the top of the previous positioning framework 100 presses downward through a press machine and other pressure devices to realize the pressing of the catalyst module, so that the gap between the two catalysts or between the catalyst and the shell in the catalyst module is eliminated, and the exhaust gas can completely pass through the catalyst when passing through the reaction chamber, thereby ensuring the exhaust gas treatment efficiency and the purification rate. As shown in FIG. 3, by the reasonable design and selection of the catalyst and the catalyst module structure and size, the catalyst module can completely fill the reaction chamber, and the gas completely passes through the catalyst along the moving direction of the gas from the inlet to the outlet.

One edge of each supporting inclined plate 2 is welded with the fixed bottom plate, and a v-shaped supporting area which is 90 degrees is formed by the two supporting inclined plates 2 in a surrounding mode. The center line of the v-shaped supporting area is perpendicular to the fixed bottom plate, so that two shells of the catalyst module can be conveniently butted, and meanwhile, a press machine and the like can conveniently apply pressure to the catalyst module before the catalyst module is welded, and gaps in the catalyst module are eliminated.
In the technical scheme, the width of the supporting inclined plate 2 is smaller than that of the catalyst module, so that the butt joint position of the two shells on the catalyst module can be exposed conveniently, and welding is facilitated. The length of the supporting inclined plate 2 is larger than that of the catalyst module, so that the catalyst module is ensured to be balanced and fixed.
In the technical scheme, the back of the supporting inclined plate 2 is connected with a vertical plate 3 which ensures that the supporting inclined plate 2 is fixed on a fixed base plate at an included angle of 45 degrees, the bottom edge of the vertical plate 3 is welded with the fixed base plate, and the top edge of the vertical plate is welded with the back of the supporting inclined plate. The side surface of the supporting sloping plate 2 facing the fixed bottom plate and the side surface of the vertical plate 3 far away from the supporting sloping plate 2 are respectively provided with a reinforcing rib plate 4. This technical scheme's design for on the premise of guaranteeing that positioning mechanism 100 weight is not too big, support swash plate and riser have sufficient intensity, be convenient for on the one hand take and shift positioning mechanism 100, on the other hand guarantees that positioning mechanism 100 has sufficient intensity, is convenient for exert pressure to the catalyst module of welding, eliminates the gap.
