Description

The invention relates to equipment for carrying out adsorption processes in a gas (steam) - adsorbent system.

The closest technical solution to the claimed object is an adsorber containing a housing with a lid and a bottom and an adsorbent layer located between them, according to a.c. USSR No. 516415, B01D 53/02 of 01/23/74.

A disadvantage of the known adsorber is that it does not provide a high degree of purification of the gas stream from the target component.

The technical result is an increase in the degree of purification of the gas stream from the target component by increasing the contact area of the adsorbent with the target component.

This is achieved by the fact that in a vertical adsorber containing a cylindrical body with a cover and a bottom, a loading hatch, a fitting for supplying the initial mixture with a distribution grid, a fitting for venting vapors during desorption, and a fitting for a safety valve are mounted in the cover, and at the junction of the cover and a stiffening ring is provided for the casing, and in the middle part of the casing on the support ring there are beams with supports supporting the grate, on which a layer of gravel is laid, the adsorbent layer being located between the an avia and a net on which goods are located to prevent adsorbent entrainment during desorption, and the spent adsorbent is unloaded through a discharge hatch installed in the housing, and a bubbler and inspection hatch with a fitting for condensate drainage and water supply are mounted in the bottom, the bubbler is made of a toroidal shape and fixed on the conical surface of the bottom by means of spacers, and the perforation coefficient of the toroidal surface of the bubbler lies in the optimal range of values: K = 0.5 ... 0.9, and the fitting for the removal of cleaned for is located on the conical surface of the bottom, while the adsorption and desorption process proceeds with the following optimal ratios of the components making up the apparatus: the ratio of the height H of the cylindrical part of the body to its diameter D is in the optimal ratio of values: H / D = 0.73 ... 1.1; the ratio of the height H of the cylindrical part of the body to the thickness S of its wall is in the optimal ratio of values: H / S = 220 ... 275; the ratio of the height of the adsorbent layer H 1 to the height H of the cylindrical part of the housing is in the optimal ratio of values: H 1 / H = 0.22 ... 0.55; the ratio of the height of the adsorbent layer H 1 to the height H 2 of the gravel layer is in the optimal ratio of values: H 1 / H 2 = 5.0 ... 12.0, and the adsorbent is made in the form of balls, as well as solid or hollow cylinders, arbitrary grains surface obtained in the process of its manufacture, as well as in the form of short segments of thin-walled tubes or rings of equal size in height and diameter: 8, 12, 25 mm.

In Fig.1 shows a frontal section of the adsorber, in Fig.2 - an adsorbent made in the form of hollow balls, on the spherical surface of which a helical groove is cut, in Fig.3 - an adsorbent made in the form of cylindrical rings, on the side surface of which a helical groove is cut , Fig. 4 is a section B-B of Fig. 3, where a helical groove is cut, having a section perpendicular to the helix, a profile of the Berl saddle or Itallox saddle, and Fig. 5 is an adsorbent made in a spherical shape.

The vertical adsorber comprises a cylindrical housing 12 with a conical cover 9 and a bottom 21. A loading hatch 4, a fitting 5 for supplying the initial mixture, drying and cooling air through a distribution grid 6, a fitting 7 for venting desorption vapors and a fitting 8 for the safety valve. A stiffening ring 11 is provided at the junction of the cover 9 and the housing 12. In the middle part of the housing 12, beams 17 with supports 22 are mounted on the support ring 14, supporting the grate 15, on which a layer of gravel 1 is laid. The adsorbent layer 13 is located between the gravel layer 1 and mesh 3, on which the goods 10 are located to prevent the entrainment of the adsorbent during desorption. The discharge of the spent adsorbent 13 is carried out through the discharge hatch 2, mounted in the housing. In the bottom 21, an inspection hatch 18 is mounted with a fitting 19 for condensate drainage and water supply, as well as a bubbler 20 with a fitting 23 for supplying water vapor through the bubbler. The bubbler is made of a toroidal shape and mounted on the conical surface of the bottom 21 by means of spacers. The perforation coefficient of the toroidal surface of the bubbler lies in the optimal range of values: K = 0.5 ... 0.9. The fitting 16 for the removal of purified gas is located on the conical surface of the bottom 21.

The process of adsorption and desorption occurs at the following optimal ratios of the components making up the apparatus: the ratio of the height H of the cylindrical part of the body to its diameter D is in the optimal ratio of values: H / D = 0.73 ... 1.1; the ratio of the height H of the cylindrical part of the body to the thickness S of its wall is in the optimal ratio of values: H / S = 220 ... 275; the ratio of the height of the adsorbent layer H 1 to the height H of the cylindrical part of the housing is in the optimal ratio of values: H 1 / H = 0.22 ... 0.55; the ratio of the height of the adsorbent layer H 1 to the height H 2 of the gravel layer is in the optimal ratio of values: H 1 / H 2 = 5.0 ... 12.0.

The adsorbent 13 is made in the form in the form of balls, as well as solid or hollow cylinders, grains of an arbitrary surface obtained during its manufacture, as well as in the form of short segments of thin-walled tubes or rings of equal size in height and diameter: 8, 12, 25 mm.

To increase the degree of purification of the gas stream from the target component by increasing the contact area of the adsorbent with the target component, the adsorbent 13 in shape can be made in the form of hollow balls, on the spherical surface of which a helical groove is cut (figure 2), or in the form of hollow balls, on a spherical surface of which a helical groove is cut, having in cross section perpendicular to the helical line a profile of the “Berl saddle” or “Itallox” saddle type (Fig. 4). The adsorbent 13 can be made in the form of cylindrical rings, on the side surface of which a helical groove is cut (Fig. 3). The adsorbent 13 can be made in the form of cylindrical rings, on the side surface of which a helical groove is cut, having in cross section perpendicular to the helical line a profile of the Berl saddle or Itallox saddle (Fig. 4). The adsorbent 13 can be made in the form of toroidal rings (not shown in the drawing). The adsorbent 13 can be made in the form of toroidal rings having a profile such as a “Berl saddle” or a Itallox saddle (not shown in the drawing).

In order to increase the degree of purification of the gas stream from the target component by increasing the contact area of the adsorbent with the target component, the adsorbent is spherical in shape (Fig. 5), in which non-through radial recesses are made, the recesses being in the form of cylindrical, conical, spherical surfaces, or any surface bodies of revolution, for example a paraboloid, an ellipsoid.

The adsorber works as follows.

The gas (steam) stream for cleaning is fed to the upper part of the apparatus through the nozzle 5 for supplying the initial mixture through the distribution grid 6. The purified gas stream is discharged from the adsorber through the nozzle 16. The adsorbent is loaded through the loading hatch 4, and the spent adsorbent is removed through the unloading hatch 2. Desorption is carried out by supplying water vapor through the nozzle 23 to a bubbler 20 having a perforated toroidal surface for a more uniform course of the desorption process. The fitting 7 is provided for the removal of vapors during desorption, and a safety valve is installed in the fitting 8 for a trouble-free flow of the process.

The proposed device can significantly increase the degree of purification of the gas stream from the target component and can also be used in recovery plants with a capacity of up to 30,000 m 3 / h.
