    The invention relates to a device for conducting gas-phase reactions.
    The aim of the invention is to increase productivity and simplify the design.
    Figure 1 shows a device, a longitudinal section; in FIG. 2 - section aa in figure 1; in FIG. 3 - section BB in figure 1; in FIG. 4 - pipe detail; on Fig, 5 - the implementation of the device with pipes of different diameters; in Fig.6 the layout of the device with multiple cameras ·, in Fig. 7 - same, top view.
    The invention can be used to produce synthesis gas from hydrocarbons using oxygen as an oxidizing agent. For example, both gases can be methane or natural gas and oxygen.
    The device comprises a chamber 1 with a mixing or reaction zone 2 and a gas introduction pipe 3, over which cylindrical pipes 4-6 are mounted. These pipes are connected together along the generatrix and are held in the outer shell of the chamber 1, which itself is connected to the outer pipes also along the generators.
    Cylindrical pipes form inter-tube free gaps between them, limited on the outer row of pipes 4-6 by the inner wall of the outer shell of the chamber 1.
    Some pipes have tapering zones (narrowing) 7 in the lower part, which are located at approximately the same level to form a network of pipelines supplying annular gaps.
    In FIG. 1-3, the central pipe does not have a narrowing, since the narrowing of the pipes enclosing it serves to supply the annular gaps.
    SU „, 1597091 AZ
    According to FIG. 1, at the lower end of the tubes, the annular zdzors are clogged, for example, with an airtight putty 8 or one or more plates or walls. This, in particular, makes it possible to hold the pipes in place by attaching plates or walls to the outer shell 9. Thus, the gas supplying the network formed by the narrowing zones is supplied through the annular gaps and the mixing or reaction zone 2.
    The narrowing zone 7 may be in the form of a torus or any other Form, which makes it possible to provide power to the annular gaps.
    In FIG. 1, the outer shell of the chamber 1 above the pipes 4-6 has a reaction zone 2, which ends with a lid 10 with an outlet 11 for eFluents.
    In the lower part, the chamber 1 has a pipe supply zone 12 with one of the gases, to which a supply pipe 3 is connected. This chamber feeds the pipes, and not the annular gaps, due to the presence of clogging means (putty, or plates or walls) of the annular gaps.
    Gas supply of the annular gaps is carried out through the pipe 13, which enters the hole 14, made on the outer shell of the chamber 1 at the level of the narrowing zones 7.
    In addition, the outer shell may have a groove at the level of the tapering zones 7, which facilitates the supply of various tapering zones 7, and a distributor channel 15 formed between them.
    The diameter of the pipes may vary. The number and / or shape of the pipes allows you to control the rate of introduction of gases and, therefore, the speed of their mixing.
    The device operates as follows.
    Gases through pipe 3 enter the internal volume of the pipes and exit into mixing zone 2.
    Gases entering through the pipe 13 are distributed along the channel 15, formed by various tapering zones 7, for feeding the gaps and for mixing.
    The length of the pipes, and the annular allows you to get in them established intersection 2 • 55 i
    gap flows with a uniform structure of gases entering zone 2 mixing.
    The device may have several chambers 1. These chambers in the amount of 7 pieces are placed in a sealed chamber 16. It is preferable that these cells are not joined by the walls of the cell and not joined with the walls of this chamber.
    The chamber 16 may be filled with coolant for heat exchange with the cameras. Depending on the needs, both coolant and refrigerant can be supplied to chamber 16.
    The pipelines 17 and 18 connected to the chamber 16 make it possible to circulate the coolant in it.
    Pipelines 19 allow gas to be supplied to the power chambers 1 of various zones, while pipelines 20 allow gas to be supplied to the annular gap power supply network.
    Pipelines 21 collect eFluents 25 coming from p'alichny chambers 1.
    A multi-chamber type reactor can be used to produce synthesis gas from an oxidizing gas such as oxygen and a combustible gas such as hydrocarbons.

    - 3 According to lig.1, at the lower bend of the pipes, the annular essers are plugged, for example, with hermetic putty 8 or with one or several plates or walls. This, in particular, makes it possible to hold the pipes in place and secure the plates or walls to the outer sheath 9. Thus, the gae, the supply network formed by the narrowing of the cis zones, is fed through the annular gaps and the mixing or reaction zone 2. The tapering zone 7 may be in the form of a torus or any other Form, making it possible to provide power to the annular gaps. FIG. The I outer shell of the chamber 1 above the tubes 4-6 has a reaction zone 2, which ends with a lid 10 with an outlet 1 for the outlet. In the lower part, chamber 1 has a feed zone 12 of the pipes by one of the gaps to which the feed connection 3 is connected. This chamber feeds the pipes, not the annular gaps, due to the presence of blocking means (putty, or plates or walls) of the annular gaps. The gas supply of the annular gaps is carried out through the pipeline 13 which enters the hole 14, made on the outer shell of the chamber 1 at the level of the narrowing zones 7. Moreover, the outer shell can have at the level of the narrowing zones 7 a groove that facilitates the powering of the various narrowing zones 7, and the distribution channel 15, which is engraved between them. The diameter of the pipes can be different. The number and / or the shape of the pipes make it possible to control the rates of introduction of ha and the speed of their flow and, consequently, their displacement. The device works the following sat. The gases through the pipe 3 enter the internal volume of the pipes and exit at the bottom of the 2 mixes. The gases entering through the conduit 13 are distributed through the channel 15 formed by different tapering zones 7, for feeding the annular gaps and for entering the mixing zone 2. The length of the pipes, and the annular gaps allows to stream them into established 1 flows with a uniform structure of gases entering the mixing zone 2. The device may have several chambers I. These chambers in the amount of 7 pieces are placed in a sealed chamber 16. Preferably, these cells do not join with the walls of the cell and do not join with the walls of this chamber. Chamber 16 may be filled with coolant for heat exchange with the chambers. Depending on the needs of the chamber 16, both coolant and coolant can be supplied. The piping 17 and 18 connected to the chamber 16 allow the circulation of the coolant therein. The pipelines 19 allow gas to be supplied to the supply chambers 1 of the various zones, while the pipelines 20 allow gas to be supplied to the annular gap supply network. Piping 21 collects ayoutients coming from different chambers 1. A multi-chamber type reactor can be used to produce synthesis gas from an oxidizing gas such as oxygen and a combustible gas such as hydrocarbons. Claims. one .
