Description

one

This invention relates to instrumentation of gas cleaning processes by adsorption in a stationary layer.

The purpose of the invention is to increase the efficiency of the device by increasing the density of the sorbent and facilitating its unloading.

FIG. 1 shows a vertical annular adsorber, a general view, in FIG. 2 is a section A-A in FIG. 1; in fig. 3 — node 1 in FIG. 2 (fastening the segments of the inner lattice between themselves); FIG. 4 shows a lattice section with vertical corrugations.

The adsorber includes a housing 1, a conical cover 2, a bottom with cones 3 and 4, cylindrical grids 5 and 6, fittings 7-11 for input and output phases and an annular shutter 12 with a mechanism 13 for vertical movement. Lattices 5 and 6 are installed in the housing coaxially, and between them a layer of sorbent is placed on the conical support 14

15. Mechanism 13 is made of stock.

16 connected to the annular shutter 12 with the possibility of limited axial movement of the shutter relative to the stem. A spring 17 is coaxially mounted on the rod, the upper end of which rests on the washer 18, and the lower end - on the bolt 12.

The upper end of the stem 16 is provided with a thread on which a nut 19 is screwed, resting on a disk 20 provided with an upper abutment. An annular shutter 12 is coaxially mounted in the internal grid 6. The grid 6 is configured to change the diameter of the cylinder under the action of applied forces.

It is advisable to form the cylindrical lattice in the form of separate segments 21 with joints in the form of overlays of their side parts, with the finger 22 of the adjacent segment being placed in the horizontal slot 23 of another segment.

The grille 6 can be made with vertical corrugations 24. The grille 6 is provided with vertical stiffening ribs 25 with inclined slots 26, the upper part of which is closer to the surface of the lattice, and the lower part, respectively, further.

In slots x 26 are placed with the ability to move along them axis

27, mounted on brackets 28 to the rod 16.

The device works as follows,

5 The gas to be cleaned flows through the fitting 8 into the internal cavity of the collector formed by the cones 3 and 4 and into the internal cavity of the cylindrical lattice 6,

 O, where it passes through the layer of sorbent 15, is cleaned, enters the annular cavity formed by the housing and the grating 5 and is removed through the nozzle 7,

15 The sorbent is loaded through the upper part of the body. Removal of the sorbent from the layer is carried out by raising the shutter 12 to the extreme upper position. The lifting of the bolt is carried out by rotating the nut 19 with an allen key with the plug removed.

The sorbent discharged from the bed fills the internal cavity of the cone.

25 3 bottoms with the formation of a cone, the slope of which forms equal to the angle of the natural; slope sor & After the formation of a cone, the precipitation of the sorbent from the layer ceases,

The sorbent is unloaded from the adsorber through fitting 11. Due to the fact that during the lift of the bolt 12 up, the axles 27, which are fixed on the brackets 28 to the rod 16, are also pinched; they come along inclined slots 26, they cause - the alignment of the segments 21 to the center with a decrease in the diameter of the cylindrical grid 6. The fingers 22 slide along the slot 23 and do not prevent the diameter from decreasing.

In the case of using a corrugated grid 6, its corrugations are compressed.

 Reducing the diameter of the internal grid 6 while simultaneously raising the gate 12 causes a gap (void) to form between the grid 6 and the sorbent 15, which facilitates relocation of the sorbent down to the unloading site and eliminates its hanging in certain zones.

After removing the spent 35 sorbent, the shutter 12 is lowered until it touches the support 14. In this case, the spring 17 must be partially compressed, and the axes 27 must

do not reach the lower end of the slots 26,

A new sorbent is poured through the upper part of the Cornus, after which the nut 19 displaces the stem 16, which compresses the spring on the already fixed gate, and the axes 27, moving down the notch 26, create expansion forces that increase the diameter of the lattice 6 and compact the sorbent excluding the formation of voids in it.

When using a stripping agent, for example, water vapor, the latter is fed to fitting 9 and then through the annular gap between the casing and grid 5 to the sorbent layer. The spent vapors enter the internal cavity of the grill 6 and are then removed through the fitting 10. The condensate formed during desorption drains onto the support 14, then collects in the lower part of the body and is removed through the fitting 11.
