Abstract

FIELD: machine engineering.
SUBSTANCE: filter with adsorbent 9 of continuous action contains a housing 1, an inlet 2 and an outlet 3 nozzles, elements with suspended layers of the adsorbent 9. A bump stop is mounted in the housing after the inlet nozzle. The elements with suspended layers of the adsorbent 9 consist of perforated support grids 8 made cylindrical or as part of an ellipsoid. The grids 8 are provided with shutters 4 for loading and unloading the adsorbent 9 from below and from above. In the middle part the grids 8 are connected to the housing 1 and to each other by means of a perforated partition 5. A vibrator 6 is mounted on the perforated partition 5. The adsorbent 9 is made in the form of a cylindrical ring, on the lateral, inner and outer surfaces of which a screw thread is made in opposite directions, or in the form of a ball on the surface of which blind holes of hemispherical shape are made, or in the form of a ring on the outer surface of which a screw surface is made by the type of a plate auger, or in the form of at least a three-bladed propeller.
EFFECT: invention increases degree of gas flow cleaning of target component and dust.

Description

The invention relates to equipment for carrying out adsorption processes for collecting mist of various acids, for example in a sulfuric acid packed column.

The closest technical solution to the claimed object is a granular filter with an adsorbent of continuous action, including a cylindrical body, the upper part of which is made in the form of a conical-cylindrical chamber, in which a hopper is mounted in the form of a cone with a perforated side surface tilted downward, mesh plates with suspended layers adsorbent and transfer devices according to the patent of the Russian Federation No. 2282484, 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 and dust by increasing the contact area of the adsorbent with the target component.

This is achieved by the fact that in the filter with a continuous adsorbent containing a housing, inlet and outlet pipes and elements with suspended adsorbent layers, a chipper is installed in the housing after the inlet pipe, elements with suspended adsorbent layers consist of perforated support grids made in cylindrical or in the form parts of the ellipsoid, while the gratings from below and above are equipped with shutters for loading and unloading the adsorbent, and in the middle part they are connected to the housing and to each other by means of a perforated partition, and a vibrator is installed on the perforated partition, the adsorbent is made in the form of a cylindrical ring, on the lateral, internal and external surfaces of which screw cutting is performed in opposite directions, or in the form of a ball on the surface of which through holes are made hemispherical, or in the form of a ring, on the outer surface which has a helical surface in the form of a plate screw, or in the form of at least a three-blade propeller.

In FIG. 1 shows a general view of a granular filter with a continuous adsorbent, a longitudinal section, in FIG. 2-5 are variants of schemes for the shape of the adsorbent located in elements 8 with suspended layers of adsorbent.

The granular filter with a continuous adsorbent comprises a cylindrical body 1, inlet 2 and outlet 3 nozzles, elements 8 with suspended layers of adsorbent. In the housing 1, after the inlet pipe 2, a baffle is additionally installed 7. Elements with suspended adsorbent layers are made in the form of cylindrical perforated support grids 8, bottom and top having shutters 4 for loading and unloading granular adsorbent, the axes of cylindrical perforated support grids of elements with suspended adsorbent layers 9 are located on the congruent casing (not shown in the drawing), and in their middle part are connected to the casing 1 and to each other by means of a perforated partition 5, on which tanovlen vibrator 6. To increase the collection efficiency of acid vapors form perforated support grids may be formed of second-order curved surface (e.g., part of an ellipsoid of revolution).

A granular filter with a continuous adsorbent operates as follows.

The gas (steam) stream for cleaning is fed to the lower part of the apparatus through the inlet pipe 2, meets the bump 7 on its way and passes through all cylindrical perforated support grids 8, in contact with the adsorbent 9, bringing it into suspension. To increase the efficiency of acid vapor capture, a vibrator 6 is installed on the perforated partition 5, which enhances the fluidization process. The purified gas stream is discharged from the adsorber through the outlet pipe 3. The adsorbent 9 enters the cylindrical perforated support lattices 8 through the upper shutters 4, and is discharged through the lower ones. A variant is possible when the adsorbent loading will be periodic, but not continuous. The movement of the gas stream and adsorbent in this apparatus is countercurrent.

It is possible to fulfill the shape of the adsorbent (Fig. 2) in the form of a cylindrical ring, on the lateral, internal and external surfaces of which a screw thread is made (not shown in the drawing) in opposite directions.

It is possible to fulfill the shape of the adsorbent (Fig. 3) in the form of a ball, on the surface of which non-through holes are made hemispherical in shape (not shown in the drawing).

It is possible to fulfill the shape of the adsorbent (Fig. 4) in the form of a ring, on the outer surface of which a helical surface is made like a plate auger.

It is possible to fulfill the adsorbent form (Fig. 5) in the form of at least a three-blade propeller.

The proposed device can significantly increase the degree of purification of the gas stream from the target component and dust by increasing the contact areas of the moving adsorbent with the target component with the same overall dimensions of the column.
