    The invention relates to the design of gas-liquid chemical reactors and can be used to produce chlorine dioxide. A device for producing chlorine dioxide is known, comprising a vertical cylindrical body with a flap and a bottom, vertical pipes parallel to each other and externally to the axis of the body for discharging the suspension, and a heat exchanger connected by their upper ends to the bottom, and lower to each other / circulating a pump installed between the lower ends / pipes for removal of the suspension and the heat exchanger, two truncated cones, the first of which is connected to the bottom with its large base and the second with its large connection with a heat exchanger upper end, a cylindrical acid distributor with inlet radially located fittings on it, located between smaller truncated cones, a baffle plate placed in the housing, a device for removing gaseous reaction products and reagent inlet and slurry nozzles connected to the bottom part of pipe for water slurry l. . The disadvantage of this device is that it cannot be manufactured as a module and thus to be transported and installed requires considerable assembly work on site with the installation of a reboiler, or other appropriate heat exchanger, and recirculation pipes. In addition, the reboiler and recirculation pipe installation devices require large production areas. In this case, in the known device, the efficiency of the process is insufficient. The purpose of the invention is to intensify the Process and simplify the design by improving the recycling of the reactants and adiabaticly expanding their flow. The goal is achieved by the fact that the device for producing chlorine dioxide / containing a vertical cylindrical body with a lid and bottom, vertical / aligned parallel to each other and eccentric body axis / pipe for removing the suspension and the heat exchanger / connected with their upper ends to the bottom and the bottom - with each other, a circulation pump installed between the lower ends of the pipe to drain the suspension and the heat exchanger, two truncated cones, the first of which is connected to the bottom with a large base and the second is a pain The base is connected to the upper end of the heat exchanger, a cylindrical distributor of acidic with inlet / radially located on it fittings between, smaller bases of truncated cones, a baffle plate placed in the housing / device for removal of gaseous reaction products and inlets, yes reagents and pulp outlets connected to the lower part of the pipe for removal of the suspension / provided with a vertical partition / fixed on the bottom and forming a channel with the inner wall of the housing The nip is larger than the base of the first truncated cone with the upper part of the body, and the branch wall is fixed on the inner wall of the body above the channel. The channel is made of rectangular cross section with an outlet end tangentially bent to the inner wall of the hull box, rectangular section, and the device for removal of gaseous reaction products is made in the form of a curved pipe located at the top of the body under the lid with an inlet end directed toward the lid. Figure 1 shows the device with private longitudinal sections, a general view; figure 2 - section aa in figure 1.. on fig.Z - the upper part of the body, a longitudinal section; in fig. 4 shows a section B-B in FIG. 3 in FIG. 5 a device according to a second embodiment / general view. A device for producing chlorine dioxide, contains a vertical cylindrical body 1 with a lid 2 and a bottom 3, vertical ones parallel to each other and eccentric to the body axis t-rub 4 for removing the suspension and heat exchanger 5 / connected by its upper ends to the bottom 3 with a friend / circulation pump b, installed between the lower ends of the pipe 4 for removing the suspension and heat exchanger 5 / two truncated cones 7 and 8, the first 7 of which are connected to the bottom with their large base with their large base m is connected to the upper end of the heat exchanger 5, a cylindrical distributor 9 of acid with inlet radially located fittings 10 located between smaller bases of truncated cones 7 and 8, a baffle 11 placed in the housing, pipe 12 to drain the gaseous reaction products and nozzles 13 and 14 of the input of reagents and the output of the pulp, connected to the lower part of the pipe for removal of the suspension, a vertical partition 15 / fixed on the bottom 3 and forming a channel 16 with the inner wall of the body, connecting the larger bases the first truncated cone 7 with the upper part of the body, and the reflective partition 11 is fixed on the inner wall of the body above the channel 16. The channel 16 is made rectangular in cross section with the outlet end tangentially bent to the inner wall of the body of the body 17. The device 12 for removal of gaseous the reaction products are made in the form of a curved pipe located in the upper part of the body under the lid with an inlet-END directed toward the lid 2. i The device works as follows. . . The truncated cones 7 and 8 on each side of the cylindrical distributor 9 in the type design. The Vortex tubes accelerate the release of the bone from the heat exchanger 5 into the first to the nous 8 to a high speed until the back pressure caused by the reduced cross section and acceleration does not exceed the difference in the pressure of saturated steam above the liquid in a given place and above the liquid in the housing. In this way, the recirculated heated liquid in the heat exchanger tubes prevents boiling down with boiling water. As the acid enters the distributor 9, it quickly mixes with the liquid, the mixture expands with low acceleration in the second truncated housing 7, so that the boiling of the liquid and the evolution of the gaseous product occur quietly and gradually. As the liquid begins to boil and dioxide begins to form. chlorine and chlorine on the downstream side of the distributor 9, the material that enters channel 16 is gaseous with increased amounts of liquid and solid matter suspended in it. The resulting liquid mixture enters the gas space 18 of the housing at a sufficiently low speed (for example, from 7 to 17 m / s). At the end of it, channel 16 is provided. a baffle 11 for guiding the liquid mainly horizontally and radially inward of the space 18; The aperture 19 for evacuating chlorine gas, chlorine dioxide and water vapor from the space 18 is connected with a pipe 12 which passes radially through the wall of the housing p to its the upper end, and its inner end is curved in the direction of the tail in such a way that its entrance from the version is directed to the lid 2 and is located some distance from it, located along the axis of the hull. This device facilitates the separation of entrained liquid from gaseous products in the vapor space 18, due to the fact that the gaseous material must be rotated 180 to enter the pipe 12 before it exits through the outlet 19. This movement causes the entrained drops to fall out of the gas phase in the reaction medium 20, so that the exhaust gas phase has a low concentration of entrained liquid. This latter device differs from the conventional system, in which the gas outlet is usually located along the generator axis in the upper partition, so that the gaseous products leave the casing, moving in a straight line. Conventional devices shown in Figs. 3 and 4 can be used. These devices differ from conventional fenders, which consist of metal mesh and are used for evaporating chlorine dioxide production systems by reducing the liquid entrainment of the removed gaseous phase. These devices are prone to clogging by depositing solid material and must be cleaned from time to time and therefore unsatisfactory. In addition to the advantage associated with less liquid entrainment by the target gas, using the shown construction of pipe 12, there is an additional advantage that a lower overall height is required, since the outlet 19 can be connected directly to the inlet of the adjacent condensation equipment instead of , have pipes that are directed vertically at the beginning upwards from the outlet in the upper partition, and then downwards to the entrance to the condensation equipment. The device of the heat exchanger 5 and the recirculation line of the reaction mixture in the embodiments of the invention are perfectly different from the design shown in the prototype. In particular, a portion of the recirculation line from the acid inlet to the discharge above the liquid level is carried out via a channel 16 inside the outer wall of the housing, in contrast to the prototype, where the recirculation line includes an inwardly bent pipe completely located outside the housing. The presence of a vertically disposed channel 16 from the bottom 3 to some distance above the level of the reaction medium 20 allows for a more compact overall structure that can be pre-assembled for transport and then transported in a modular form so that installation on site disappears and consequently saves by
    compared to expensive prototype design.
    In addition, since the outer recycle pipe of a known structure is excluded, the requirements for the outer volume of the entire installation are reduced and this costly circumstance is also removed.
    Tube 4 to remove slurry; shown at some distance, although parallel to the axis of the housing. Such a device is a consequence of the size of the diameter of a particular apparatus and the consequence of the need to locate the heat exchanger 5 under the casing. For larger vessels than shown, where there is more space under the hull, a pipe 4 for removing the suspension is usually located along its axis.
    In the interest of maintaining a compact form, it is preferable to have a heat exchanger 5 such that it fits completely into the dimensions of the body. The actual external size of the heat exchanger 5 depends on the performance of the device, the diameter of the pipe 4 to remove the suspension and the performance of the pump 6.
    Although a vertical channel 16 is shown on one side of the housing, this design is a convenient version of the device. Another possibility is to form channel 16 in such a way that it ends at its upper end in the form of a circular or other appropriately shaped opening, located across the center of the body above the level of the reaction medium 20 at a distance from this central opening. it liquid in the direction of the walls of the generator may be provided with a partition 11.,
    Zhodnitsa In the housing of the liquid figure 1 and. 2) usually moving radially with respect to its axis in the reaction medium 20. The variant shown in Figures 3 and 4 illustrates a modification of this device in which the internal partition 15 is curved inside the vessel at its upper end to form a vertical rectangular output end 17 facing the inner wall of the housing and intended to impart incoming liquid in the main tangential motion. Tangential entry of recirculated liquid promotes separation from liquid
    gas phase, so that the steam separation space can be smaller.
    In the device of FIG. 3 and 4, a more conventional conical tank 3 and a gas outlet along the axis of the apparatus through an opening 19 are used, although in this case the structures shown in Figs 1 and 2 can also be used.
    Thus, the pump 6, the heat exchanger 5 and the distributor 9 for introducing acid are placed outside the housing, although they form part of a common modular installation. Such a device of individual parts is very advantageous because it allows easy installation of each of these parts without disassembling the entire installation and does not require access to the inside of the case. Accessibility for maintenance may be a disadvantage of more integrated designs.
    Thus, the structures shown in FIG. They represent the combination of individual parts into a compact modular installation for the production of chlorine dioxide without the need to create an integrated assembly from a single apparatus. In this compact modular installation, separate parts requiring maintenance are easily accessible.
    From the point of view of possible maintenance difficulties, more integrated structures can be used, having benefits associated with the internal partition and with the recirculation device. In Fig. 5, parts in the form of truncated cones 7 and a distributor 9 for the entrance of acid can be provided in the form of parts of the internal partition 15 near the lower end of the bottom 3.
    In addition, a heat exchanger 5 with adjacent lower and upper parts is provided, connected at the upper end directly to the core, the bottom and at the lower end to the pump b, into which sodium chlorate solution 13 enters and from which sodium sulfate suspension is discharged through pipe 14 In this device, pipe 4 is excluded. The pump casing may have the shape shown or a more familiar shape similar to that used in FIG.
    Thus, the invention provides improved methods and apparatus for producing chlorine dioxide. Modifications are possible within the scope of this invention.
