SU1225605A1 - Adsorber - Google Patents

Description

The invention relates to an adsorption technique and can be used in the oil refining, chemical and other sectors of the industry, in particular in the separation of gaseous liquid mixtures with zeolites in a fixed bed of adsorbent.

The purpose of the invention is to increase the efficiency of operation by improving the mixing of the gas flow.

Figure 1 shows the adsorber, a longitudinal section; FIG. 2 shows the node I in FIG. one

The adsorber contains a vertical cylindrical body 1, a support grid 2, an adsorbent layer 3, perforated glasses 4, a gas distribution device comprising the upper 5 and lower 6 truncated cones with openings 7 and 8. In housing 1 there are fittings 9 and 10 for reactants . The angle of taper of the cones 5 and 6 is preferably greater than the angle of repose of the particles of the adsorbent, which ensures that the free space of the body is completely filled with the adsorbent, and the installation of devices for distributing the gas flow at a distance of 0.5 to 1 in diameter across the body stabilization of the wall laminar flows of the product being cleaned and ensures their repeated destruction along the height of the adsorber.

The adsorber works as follows.

The feedstock through fitting 9 and

5 supporting grid 2 enters the layer of adsorbent 3 on which the separation of the raw material. The cleaned product through perforated cups and nozzle 10 is removed from

0 adsorber. The laminar film of the product being separated from the wall of the housing 1 flows onto the lower truncated cone 6, part of the volume of the laminar film reaches the surface of the lower cone 15 and moves to the central part of the adsorbent layer while mixing with the product of the central part of the adsorber, another part of the laminar plank passes

20 through holes 8, the axes of which are arranged in pairs at an angle to each other, into the space between the lower 6 and upper 5 cones, in which individual local jets that were

5, the composition of the laminar film is intermixed, ensuring that the concentration of the component to be adsorbed is level. In connection with the creation of an injection of a new effect due to the narrowing of the flow of the product to be purified in the central part of the adsorber, the mixed product is sucked

f.

from the space between the cones through the holes of the upper cone to the central part of the adsorber.
