CATALYTIC TUBULAR CONVERTER, including a cylindrical body, inside which vertical reaction tubes are axially disposed, placed around compensatory feeders of gas vents connected to them and combined into groups, each of which is equipped with a common cover, is distinguished by the fact that In order to improve performance due to the intensification of heat exchange, each case has a petal shape, while the number of petals corresponds to the number of reaction tubes in the group. 2.Converter pop. 1, I distinguish between u and the fact that a displacer of multifaceted section is installed along the axis of the cover, while the number of faces is equal to the number of cover petals.

Description

The invention relates to the design of a catalytic tubular converter and can be used in the chemical, petrochemical, metallurgical and other industries in the production of ammonia, methanol, and hydrogen.

The purpose of the invention is to increase the productivity of the apparatus due to the intensification of heat transfer.

Figure 1 shows the catalytic tubular Converter, General view; Fig. 2 shows one group of pipes united by a common cover; on fig.Z - one group of pipes in the section.

The catalytic tubular converter consists of a lined body 1, in which vertical reaction tubes 2 filled with a catalyst are installed, enclosed several tubes in a coaxial cover 3, and stacks 4 placed between them.

A group of reaction tubes placed in one petal case, in the lower part, is connected by adapters 5 into one tube 6. The lower ends of the stands are equipped with coaxial tube grids 7 with removable caps 8.

The upper ends of the sinks are brought into a manifold located in the lid zone. To the tube sheets 7, compensating pigtails 9 are attached, connecting them to the group of surrounding each hundred to 4 reaction tubes 2 via adapters 5 and tubes 6. Inside each cover a displacer 10 is installed. Mutual fixation the covers are defined by a partition 11. The reaction tubes 2 are rigidly connected in one hermetic support grid 12, a. the covers are in another hermetic grille 13. In the housing there are a fitting 14 for supplying the vapor-gas mixture, a fitting 15 for the heat carrier inlet, a fitting 16 for its output and a fitting 17 for the output of the converted gas. Catalytic tubular Converter works as follows. The vapor-gas mixture under pressure through the fitting 14 enters the lid area of the housing I, is distributed through the reaction tubes 2. At the same time, the coolant flows into the annular space through the fitting 15, which passes along the reaction tubes 94 in the gap between the cover 3 and the tube 2, In the reaction tubes 2 in the catalyst bed, under the influence of the incoming heat, hydrocarbons are converted. The converted gas through the pigtails m 9 enters the drain 4, then into the collector and leaves the apparatus through fitting 17, the heating gas leaves the covers, enters the space formed by the grilles 12 and .1.3, and leaves the apparatus.
