Description

(54) DEVICE FOR REGENERATION OF HOSE-HELD F.PTROV

one

The invention relates to a technique for cleaning gases from dust, and more specifically to devices for regenerating filter elements of bag or pocket filters by pulsed backward blowing, and can be used in all sectors of the national economy where thin gas is used to clean gas.

Closest to the proposed regeneration device 1, consisting of. collector with nozzles placed on the movement mechanism. The purge air is supplied to the nozzles by turning on the valves at the time the nozzles pass over the filter elements by means of limit switches.

Concentrating on the mechanism for moving all the equipment and installing limit switches in the course of movement complicates the design of the device and requires mobile switching for supplying compressed air and connecting electrical control circuits, which also reduces the reliability of the device.

The purpose of the present invention is to simplify the design and ensure the reliability of the device.

This goal is achieved by the fact that in a known device for regenerating bag filters containing a collector with nozzles placed on the movement mechanism, the movement mechanism is designed as a pneumatic cylinder with a hollow shaft, the channel of which connects the direct chamber.

The device includes a pneumatic cylinder 1 with chambers 2 and 3 reverse stroke, the piston 4 and the rod 5 of which have a channel 6 for supplying compressed air to the manifold 7 with nozzles 8. The device fastens 20 s to the filter housing with a front flange 9. The fittings 10 and 11 serve for supplying air into the forward and reverse chamber of the pneumatic cylinder. Total

1 the area of the nozzle openings 8 (Zrets meniis pgguzer section 10 and the lines supplying compressed air.

Regenerating device operates as follows.

Compressed air is supplied through the nozzle 10 into the chamber of the forward stroke 2 simultaneously through the channel 6 enters the collector 7, from where it passes through the nozzles 8 into the filter elements. In this case, the piston 4, the outflow 5 and the collector 7 move in the forward direction. The resetting device is reset to its initial position by supplying compressed air through the nozzle 11 into the return chamber 3 after stopping the supply of compressed air to the forward stroke 2 chamber, and the piston 4 moves in the forward direction under pressure in the forward motion chamber

2 Counting the difference in the cross-sectional area of the nozzle 10 and the sum of the areas of the nozzles 8

Due to the fact that the air supply is supplied to the collector through the vigorous stem, the maintenance of the device is simplified, and its reliability is maintained.
