Description

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 RF patent No. 2440177, B01D 53/02.

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 and dust.

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 the annular adsorber containing a cylindrical body with a lid and a bottom made of elliptical shape, moreover, the loading and inspection hatches are mounted in the cover, and the loading hatch is connected to the hopper-compensator located in the cover, and the fitting for supplying the initial mixture, drying and cooling air is located in the lower part of the housing, in which the supports for the base are fixed under the external and internal perforated cylinders, a fitting for venting vapors and condensate during desorption and for supplying water lies in the bottom, in which the fitting is mounted for the removal of purified gas and exhaust air and for supplying water vapor, moreover, it is fixed through a manifold having two channels, and in one of which there is a shutter for the desorption process, with a bubbler, the bubbler is made in the form of a toroid the entire height of the perforated cylinders, and the fitting for the safety valve is installed in the upper part of the housing, and the adsorption and desorption process proceeds at the following optimal ratios of the components of the apparatus: nt perforation of the toroidal surface of the bubbler lies in the optimal range of values: K = 0.5 ... 0.9; the ratio of the height H of the cylindrical part of the housing to its diameter D is in the optimal ratio of values: H / D = 2.0 ... 2.5; 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 = 580 ... 875, while the adsorbent is made in the form of balls, as well as solid or hollow cylinders, grains of an arbitrary surface obtained in the process fabrication, 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, the adsorbent is made in the form of at least three coaxially located hemispherical surfaces interconnected with a gap in the middle stvom fastening element disposed axially through prostanovochnye elements in the form of rings, and between the hemispherical surfaces of the elements are fixed on prostanovochnyh corrugated elements shaped forming surface, equidistant hemispherical surfaces or adsorbent prostanovochnye elements are formed as coil springs.

In FIG. 1 shows an adsorber, a frontal section, in FIG. 2 is a section AA of FIG. 1, in FIG. 3 - form of adsorbent.

The annular adsorber comprises a cylindrical body 4 with a cover 7 and an elliptical bottom 15. In the lid 7, a loading hatch 9, an inspection hatch 8. are mounted. The loading hatch 9 is connected to a compensating hopper 10 located in the cover 7. A fitting 2 for supplying the initial mixture, drying and cooling air is located in the lower part of the housing 4, in which the supports 3 are fixed for base 13 under outer 5 and inner 6 perforated cylinders. The discharge of the adsorbent 12 is carried out through the discharge hatch 14, mounted in the lower part of the housing 4, which is fixed in at least three mounting legs 1 with support plates 18. A fitting 17 for removing vapors and condensate during desorption and for supplying water is located in the bottom 15, in which the fitting 16 is fixed for the removal of purified gas and exhaust air and for supplying water vapor. The fitting 16 is fixed through a manifold having two channels, one of which has a shutter for the desorption process, with a bubbler (not shown in the drawing) made in a toroidal shape over the entire height of the perforated cylinders 5 and 6. The fitting 11 for the safety valve is installed in the upper body parts 4.

The process of adsorption and desorption occurs with the following optimal ratios of the components making up the apparatus: the perforation coefficient of the toroidal surface of the bubbler lies in the optimal range of values: K = 0.5 ... 0.9; the ratio of the height H of the cylindrical part of the housing to its diameter D is in the optimal ratio of values: H / D = 2.0 ... 2.5; 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 = 580 ... 875.

The adsorbent 12 (Fig. 3) is made 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. The adsorbent can be made in the form of perforated cylindrical rings, on one side of which a perforated round base is rigidly attached, and on the other there is a perforated round cover (not shown in the drawing), and the cavity of the perforated cylindrical rings is filled with spherical elements made of active carbons, for example, grades BAU, AR-A, SKT-3. The adsorbent 12 may be made of porous polymeric materials, glass, porous rubber, composite materials, wood, stainless steel, titanium alloys, precious metals.

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 12 in shape (Fig. 3) is made in the form of at least three hemispherical coaxially located surfaces 19, 20, 21, interconnected with a gap by means of a fastening element, for example in the form of a bolt 22 with a nut 23, through axisymmetrically arranged spacing elements in the form of rings 24, 25, and between hemispherical surfaces are corrugated on the spacing elements e elements 26, 27, having the form of a forming surface, equidistant to hemispherical surfaces, or spacing elements in the adsorbent are made in the form of coil springs (not shown in the drawing).

Hemispherical surfaces 19, 20, 21 in the adsorbent are perforated. Corrugated elements 26, 27 in the adsorbent are perforated.

Ring adsorber works as follows.

The gas (steam) stream for cleaning is supplied to the lower part of the apparatus through the nozzle 2 for supplying the initial mixture through a distribution grid (not shown in the drawing). The purified gas stream is discharged from the adsorber through the nozzle 16. The adsorbent 12 is loaded through the loading hatch 9, and the spent adsorbent 12 is removed through the discharge hatch 14. Desorption is carried out by supplying water vapor through the nozzle 16 to a bubbler having a perforated toroidal surface for a more uniform desorption process over the entire height of the perforated cylinders 5 and 6. The fitting 17 is provided for venting during desorption, and a safety valve for trouble-free leakage is installed in the fitting 11 ia process. As an adsorbent, activated carbons of the BAU, AR-A, SKT-3 and other brands can be used.

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 more than 30,000 m 3 / h.
