The invention relates to a nozzle exchanging apparatus for gas-liquid and can find application in chemical, petrochemical, oil and gas industry, metallurgical and coke-chemical production, industrial ecology at the cleaning of flue gases and air emissions.

Known for the design of Packed columns, consisting of a housing with a nozzle inlet and outlet gas and liquid, the reference gratings with laid them on the nozzle in the form of Raschig rings, rings with partitions, rings PAL, saddles the Burleigh or Intalox". To improve wetting of the nozzle in the columns of large diameter nozzle stack layers (sections) with a height of 2-3 m and under each section set pereraspredelitel fluid to neutralize the wall effect, when the fluid flows at the walls of the column and the gas in its center. (Kasatkin A.G. Basic processes and apparatuses of chemical technology. - M.: Chemistry, 1971, eighth edition, revised, str-472).

For reasons that impede the achievement of specified technical result is the uneven distribution of liquid and gas by volume of the column, and the need for installation of pereraspredelitel fluid, which leads to an increase in the size of the column.

Known for the design of Packed columns, in which ocus on the support grid orderly laid nozzle, consisting of a perforated ring, provided with an external annular elements with longitudinal cutouts attached with fins to a perforated ring (Ed. St. USSR №294399, 01D 53/18, 1979).

For reasons that impede the achievement of specified technical result is not sufficiently uniform distribution of liquid and gas by volume of the column, when the bulk of the gas moves to the center, and the liquid on the periphery of the cross section of the column is at its walls, which leads to the necessity of installation of pereraspredelitel fluid and increasing the height of the column.

The closest technical solution to the declared object and selected for the prototype is a Packed column contact apparatus containing a cylindrical housing and a nozzle in the form of stacked ceramic rings with catalyst, when this ring is made with respect to their length to diameter of 1.5 to 2.5, and the length of the ring is 0.4 and 1.0 times the inner diameter of the shell, and when multi-row placement of rings in the body of the ring is made in the form of a one-sheet hyperboloid (Ed. St. USSR №1625518, B01J 19/30, 1991).

For reasons that impede the achievement of specified technical result is the uneven distribution of liquid and gas over the cross section and the height of the column, which reduces the rate of mass transfer, leads to the necessity of installation of redistributive is realitly fluid and ultimately increases the height of the column.

The objective of the proposed technical solution is the design of the Packed column and the nozzle and place it in the column, allowing you to evenly distribute the liquid and the gas at the height of the column, which increases the efficiency of mass transfer.

The technical result is an increase in the degree of gas purification due to the intensification of the process of mass transfer between gas and liquid.

The technical result is achieved by the fact that in the Packed column containing cylindrical body and the nozzle in the form of a multi-row placed in it rings, the side surface of the ring nozzle is curved on a circle with radius R=0.08 to 0.1 m, and the ring vertically offset set in the ranks of the convex side to the body axis of the column so that the upper exposed edge of each ring of the bottom row is placed inside the ring on the top row.

The running side surface of the ring nozzle curved on a circle of radius R at stream them from top to bottom of the liquid film, and the flow of this liquid film flow of gas moving from the bottom up, to create a centrifugal force that causes the liquid having a higher density, to move from the center of the curvature radius R, and the gas with lower density, the center of curvature.

Vertical installation in the ranks of the rings nozzles the release of the Oh-party to the axis of the chassis column allows you to create a fluid in addition to the axial component of velocity, directed from the top down, the centrifugal radial component of velocity from the periphery to the centre of the pillar, and in Gaza, in addition to the axial component of velocity directed from the bottom up, centrifugal radial component of velocity from the center to the periphery.

Bending the side surface of the nozzle rings around the circumference with radius R=0.08 to 0.1 m allows you to create centrifugal force of the same order with the force of gravity, that is, the centrifugal acceleration is equal to or slightly greater acceleration of free fall

V2/R≥g

where V is the velocity of a liquid or gas, m/s; R is the radius of the side surface of the ring nozzle, m; g=9,81 - free fall acceleration, m/s2. As the operating speeds of the gas and the liquid in the nozzle columns of the order of 1 m/s, then

R≤V2/g≈0,1

The increase of the radius R exceeds the upper limit equal to 0.1 m, leads to the decrease of the centrifugal force and reduced alignment effect of gas and liquid flows in the cross section and the height of the column that does not allow to intensively mix the liquid and gas streams.

The decrease of radius R below 0.08 m leads to an excessive increase in the centrifugal force that does not allows to evenly distribute the flow of liquid and gas over the cross section and the height of the column, which reduces the efficiency of mass transfer and mass transfer rates.

In addition, vertical mounting rings with the offset is m in series so as that the exposed edge of each ring of the bottom row is placed inside the ring on the top row, you can reduce the hydraulic resistance, to increase the stability of the rings series, and to facilitate their installation during installation.

Figure 1 shows a vertical section of a fragment of the Packed column; figure 2 - General view of the ring nozzles in the section.

The Packed column consists of a casing 1 in which is placed the ring 2 nozzles on the support bars 3; lateral surface 4 of the rings 2 the nozzle is curved on a circle with radius R=0.08 to 0.1 m, and the ring 2 are vertically offset set in the ranks of the convex side to the body axis of the column so that the protruding edge 5 of each ring of the bottom row is placed inside the ring on the top row.

The Packed column is as follows.

In case 1 the column top is liquid, which first fills the entire volume of the housing 1 for complete wetting of the entire surface of the rings 2 nozzles. Then below in column 1 is the gas.

The flow of gas around the liquid film flowing on the surface of the rings 2 the nozzle and passing through all the rows of multi-row vertically offset rings installed, extends up from the housing 1.

Since the side surface 4 of each ring 2 of the nozzle is curved on a circle of radius R=0.08 to 0.1 m, and each ring in a row vertically installed with what emeniem convex side side surface 4 to the axis of the housing 1 of the column, when the current of the liquid film on the convex side surface 4 from top to bottom therein under the action of centrifugal force occurs the velocity component directed along the radius R to the center of the column. In the gas flow flowing liquid film upwards under the action of centrifugal force, there is the velocity component directed along the radius R, but from the axis of the column to the wall of the housing 1, as the gas density is much less than the density of the liquid.

While the average axial velocities of liquid and gas of the order of 1 m/s at a radius of the side surface 4 of the ring 2 R=0.08 to 0.1 m centrifugal force that returns the liquid film to the body axis of the column and the gas flow flowing to this tape casting from the axis of the column to the body 1, it becomes of the same order with the force of gravity, which allows to mix the fluid and gas flow uniformly in the whole volume of the column as the height and radius.

A smaller value of the radius R=0.08 m preferably ring nozzle small size to small the length of the side surface 4 of the rings 2 large centrifugal force managed to create a radial velocity component of the liquid to the center of the column and the gas velocity to the body 1.

A larger value of the radius R=0.1 m, preferably for rings of nozzles of larger size, as in this case, even a smaller centrifugal force manages to create on long Bo the OIC surface 4 rings 2 desired radial component of velocity for the liquid and gas.

Thus, the proposed design of Packed columns allows for the creation of centrifugal force to move the fluid not only downwards, but also in the radial direction from the wall to the axis of the column and gas under the action of this force moves not only upwards, but also in the radial direction from the axis of the column to the wall. This increases the rate of mass transfer due to the intensive mixing of gas and liquid, a uniform filling of the total volume of the column height and the radius increases, the surface of separation of the phases by splitting of drops and bubbles of gas, prevents the movement of fluid to the wall of the column, and gas to its axis, reduces the size of the column and ultimately increases the efficiency of mass transfer.

The proposed ring nozzle is easy to install in existing nozzle columns, replacing the conventional nozzle type Raschig rings and other, or alternate the conventional nozzle, stowed in bulk, with rows offer rings of nozzles with a lateral surface, a curved circumference, and installed according to the claims.

The Packed column containing cylindrical body and the nozzle in the form of a multi-row placed in it rings, characterized in that the side surface of the ring nozzle is curved on a circle with radius R=0.08 to 0.1 m, and the ring vertically from the established offset in the ranks of the convex side to the body axis of the column so that the upper exposed edge of each ring of the bottom row is placed inside the ring on the top row.
