SU106767A1 - Catalyst cleaning device - Google Patents

Description

Devices for classifying fine-grained materials by size, which can also be used for cleaning catalysts in which dust and fines are separated from the material flow by air blowing, sieving, etc., are known. However, the devices of such designation and design are considered cumbersome by productivity and complexity.

In the described device, designed to clean ball and tablet cracking catalysts from dust and fines, these disadvantages are eliminated by the fact that a pillow grid vertical vertical section of the pipeline is used as a filter in the container silo and blown by the air flow. where the subject stream is cleaned up.

The tube with holes, supplying compressed air, blowing the flow of catalyst, is located either inside or outside the specified mesh section of the pipeline.

The design and operation of the device of FIG. 1 and 2; in fig. 1 shows a side view of the device, FIG. 2 view of the device

The pot.ht of the catalyst flows through pipes 7 and is poured from them into a vertical pipe 2, passing through the center of the bunker 5, equipped with a groove 4, supplying compressed air 5 and a breathing nozzle with an air vent 6.

Protin. pipe 2 in the day, e device introduced a pipe 7 of the same diameter. Between pipes 2 and 7 is fixed, for example, by means of clamps o, a cylindrical mesh U; the catalyst tray passes through an-cylindrical grid 9, is blown with air entering line 5, is freed from dust, and l exits the apparatus through pipe 7. Separated, dust is deposited on an inclined bottom and is discharged through pipe 10.

D. la.1Y1ysheg (sifter is used for screening the dust-free catalyst from the crumb, consisting of a grid installed in the neckline

which is

oblique tpyoi; 7. ycTpoiiТ | 1убЬ continue p1е. It requires a shut-off device).

Catalyst 1Ga crumb is poured along line 12, the screened catalyst according to INII 13.

Subject invention

Claims (2)

1. A device for cleaning a catalyst, in which dust is separated by a stream of compressed air supplied through a screen and the chips are sifted through a sieve as it moves along an inclined pipe, it differs in that. that, in order to simplify the device and increase its performance, the grid inside the bunker forms a vertical mesh pipe, inside which a tube with holes is installed, supplying compressed air. 2. An apparatus according to claim 1, characterized in that the tube with openings for supplying compressed air is located in the bunker outside of the mesh pipe.
