Preemptive execution:

shell in the lower part is equipped with a water seal or overlapped;

shell made of flat elements, closed Cabinet (see RU Patent 2279302, IPC 01D 3/32, 01D 53/18 (2006.01), 2006).

The disadvantages of the known device are increased hydraulic resistance device is VA, associated with the presence of a large number of local resistance, insufficient separation of fine threads, bulkiness and increased consumption, the complexity of manufacturing and Assembly.

Known distribution device for distribution of the gas flow over the cross section of the apparatus, and can be used in mass transfer, separation and filtration devices made in the form of a cylinder with a perforated base and mounted inside the housing of the apparatus eccentric to its axis against the nozzle gas inlet with a clearance to the casing, and a perforated base is located below the nozzle gas inlet, on the basis of a set of cylindrical shell, which is connected to the housing by a partition located above the nozzle gas inlet, and the shell is made with channels with variable cross-section for gas flow, decreasing to the axis of the location of the gas inlet nozzle.

Preemptive execution:

shell made teardrop shape with the orientation of the sharp edges forming the side of the gas inlet nozzle and placed eccentric to the axis of the apparatus; the sides of the gas inlet nozzle is divided by a longitudinal partition, the ends of which are passed through the opposite channels and flanged in the direction of the gas inlet nozzle (see R Patent 1643030 A1, IPC 01D 3/20, 1991).

The disadvantages of this device are insufficient separation of fine threads, the complexity and bulkiness of the device, the complexity of installation.

The closest in technical essence is naturally a device for uniform distribution of gas over the cross section of the apparatus, and can be used in Packed column apparatus and gas separators, which is equipped with a perforated base, the device is installed inside the enclosure against the connection of the input gas with a gap to the housing, and a perforated base is located below the nozzle gas inlet, the gas distribution device is made in the form of a triangular prism on the side which has the units of vertical corrugated sheets, the corrugations of which are at an angle to the horizon, and in the adjacent sheets of the unit corrugation is made of a cross (see RU Patent 2329849, IPC 01D 3/00, B01D 3//32 (2006.01), 2006).

The drawbacks are the uneven distribution of gas flow over the cross section of the apparatus and insufficient separation of fine streams with high values of factor speed (w>40) in the connection of the input gas mixture, which is associated with structural features of the device and the secondary dispersion and the DNA is om separated dispersed particles.

The objective of the invention is a uniform distribution of gas flow over the cross section of the apparatus and improving the quality of separation of fine streams at high values of the factor of speed in the connection of the input gas mixture.

The technical problem is solved in that the gas distribution device installed inside the enclosure against the nozzle gas inlet with clearance to the body and is made in the form of a polygonal prism, on the side which has blocks of corrugated sheets, the corrugations of which adjacent sheets made cross, the device is made in the form of a hexagonal prism, which is coaxially located inner cylinder having a slit or perforation, the cylinder length is divided into sections of circular disks with a diameter decreasing from the inlet gas injection.

Pre-emptive execution, when the space between the hexagonal prism and the inner cylinder filled with irregular nozzle.

Technical solution allows to improve the uniformity of the gas phase over the cross section of the apparatus and to improve the quality of separation of fine streams at high values of the factor of speed in the connection of the input gas mixture.

1 shows a view of the distribution device-side connection of the input gas, figure 2 shows usersproperties device in a perspective view, figure 3 shows the distribution device in the device.

Naturally the device is made in the form of hexagonal prisms 1 and set against the nozzle gas inlet 2 with a clearance to the casing 3, on the sides of the prism set blocks of 4 of the corrugated sheets 5, the corrugations of which adjacent sheets made cross, hexagonal prism is coaxially located inner cylinder 6 having slots or perforations 7, the inner part of the cylinder length is divided into sections 8 of the ring discs 9 hole diameters decreasing from the inlet of the gas inlet, the space between the hexagonal prism and the inner cylinder at a preferential execution completed an irregular nozzle 10.

The proposed gas distribution device operates as follows.

The gas phase contains dispersed particles serves radially through the nozzle gas inlet 2 to the gas distribution device, the body of which is made in the form of a hexagonal prism. The gas stream with a high value of the factor of speed through the nozzle gas inlet 2 is served in the gas distribution device, where it gets in section 8 coaxially located inner cylinder 6 formed by an annular disk 9 with a diameter decreasing from the inlet of the gas inlet. Next, the flow through the spruce or the perforation 7 of the inner cylinder 6 is held in blocks of 4, made of corrugated sheets 5, the corrugations of which adjacent sheets made cross. The edges of the corrugated sheets 5 divide the gas stream at the entrance to the blocks into separate streams which, passing between the sheets, squish around corrugations, under the influence of inertial forces on the surface of the leaves occurs the precipitation of the dispersed particles and the formation of liquid films under the influence of gravitational forces trickle down.

In sections 8, thanks to the ring discs 9 hole diameters decreasing from the inlet of the gas inlet 2, is the alignment of the velocity profile of gas, and the prismatic shape of the distribution device enables you to evenly distribute the gas flow over the cross section of the apparatus 3. Large flow section 4 blocks significantly reduces the factor of the gas velocity, which prevents secondary dispersion formed by corrugated sheets of the liquid film, and improves the quality of separation of fine particles.

In the case of filling the space between the hexagonal prism and the inner cylinder irregular nozzle 10 is more uniform distribution of the gas stream. Under the influence of inertial forces on the surface of the Packed items is the precipitation of the dispersed particles and the formation of liquid films under the influence of gravitational forces trickle down.

p> The device is easily assembled from component parts that allows you to feed it into the machine through the hatch and install the device in new and existing devices.

Thus, the inventive design of the gas distribution device enables you to evenly distribute the gas flow and to improve the quality of separation of fine particles of liquid at high values of the factor of speed by smoothing the velocity field of the gas stream and reduce its speed at the exit of the device due to a substantial increase in the deposition surface and the bore of the device for the gas stream.

Declare the object passed industrial tests in the gas separator and showed good results.
