The invention relates to the design of apparatus for the separation and purification of gas using a bulk adsorbent.

The purpose of the invention is the reduction of the gas purification level by increasing the uniformity of gas degrading over the adsorbent layer.

FIG. 1 shows a diagram of the adsorber, a longitudinal section; FIG. 2 is a section A-A in FIG. 1; Fig. 3 shows the assembly 1 in Fig. 1 (the assembly of an abutment of a hollow guide against the wall of the housing, a fence slot); in FIG. 4, node II in FIG. 1 (an assembly of an abutment of a hollow guide to a pipe in the central part, an outlet slit).

The adsorber contains a cylindrical body 1 with an inlet 2 and an outlet 3 with nozzles, a supporting distribution grid 4 with a bulk adsorbent 5, an upper grid 6 and a device for distributing gas over the cross section of the housing, made in the form of a coaxially reinforced spiral guide 7, the angle of which is to the horizontal axis equal to 1.1-1.6 of the angle of repose of the bulk adsorbent, Guide 7 can be made rotatable and equipped with an actuator 8,

The guide 7 is made hollow, while its bottom wall 9 is made on the side of the housing wall with a continuous screw intake slot 10., and on the side of the central part, at the pipe 11 of a similar shape, with an outlet slot 12.

The cavity 13 of the guide 7 is equipped with radial partitions 14. The housing 1 is equipped with a loading hatch 15,

The adsorber works as follows.

per turn of the helix is 1.1-1.6 of the angle of repose of the sorbent,

4. The adsorber on PP. 1-3, of that time; and with the fact that the cavity of the guide is provided with radial partitions.

Cleaning gas is fed into the pipe 2, passes through the reference distribution grid 4 into the layer of adsorbent 5 and then passes in a spiral into the layer of adsorbent enclosed between the adjacent turns of the guide 7, and then goes through the pipe 3 to the consumer.

Due to the fact that the peripheral gas layers go a long way along their spiral helix, despite the looseness of the wall adsorbent, they generally experience about the same resistance as the inner gas layers that pass through the denser layers of the adsorbent, but more short cut Therefore, a uniform gas flow is ensured throughout the cross section.

In order to increase the density of the adsorbent and further increase the uniformity of the passage of gas through the cross section of the casing, the spiral guide is turned at a certain angle after the loading of the fresh adsorbent. In this case, the helix works as a screw, compacts the adsorbent both in height and in the radial direction.

By the need of turning the guide, it is possible to eliminate the hangup of the adsorbent in certain areas.

In the case of using a hollow gas guide, passing through the peripheral zone, it enters the helical intake slot 10 and, by means of radial partitions, exits the slot 12, thereby redistributing the flow over the cross section.

Since the gas inlet and its outlet are carried out continuously in height (along screw holes)

uniformity of gas distribution over the cross section of the housing.

Due to the fact that the angle of inclination of the spiral-shaped guide exceeds the angle of repose of the bulk

When the fresh adsorbent is loaded through the hatch 15, the adsorbent rolls down along the helical surface of the guide 7 downward without any additional effect and is evenly distributed over its cross section.
