(54) DEVICE FOR CLEANING AIR

The invention relates to filtration and can be used in the chemical, mining and other industries for air purification. A device for air purification is known, comprising a housing, divided by height by partitions forming the purified air chamber, a dusty air chamber and a purge chamber placed between the latter and connected to a source of compressed air, filtering the sleeves placed in the cooled air chamber –l connected to the cleaned air chamber with pipes passing through the purge chamber and forming a partition separating the purge chamber from the dusty air chamber, annular channels that cross You valve II. A disadvantage of the known device is small cleaning efficiency, high energy consumption. A distinctive feature of the proposed device is that the valve is made in the form of an inflatable elastic ring. It is advisable to make the inflatable ring in the form of a shaped babe, on it to fasten the edges of an elastic material, which with the inner surface of the babynzhi forms strips t for supplying compressed air. FIG. 1 shows iipejuiaraeMoe device, general view; pas figs. 2 - node 1 fng. I; in fig. 3 - node II of FIG. 2. The air cleaning device includes 1, which is divided in height by partitions 2 and 3, forming a chamber 4 of dusty air, a chamber 5 of purified air and a purge chamber 6. In the chamber of dusty air there are filtering sleeves 7, in the upper part of which there are pipes 8, passing through the purge chamber 6 and forming annular channels 9 with a partition 2. At the reversal 2 from the chamber side of the dusty air 4, a valve in the form of an inflatable, elastic koiyoz is strengthened. The valve includes profiled 1 "1st babzhzhu 10, which is covered with elastic material P, reinforced on it with its edges. The cavity formed between the female and the elastic material is connected to the compressed air pipe 12 and to the pipes connected to the female 10. The body has several valves 13 for removing air, which include a cylindrical shell 14 with holes 15 for

air removal. A cylinder 6 is mounted along the shell axis, one of the end edges of which is welded to the outer wall of the purge chamber 6, and the free edge is the valve seat 13 to which the elastic membrane 17 adjoins). The shell 14 and the cylinder 16 form a chamber 18 for air is removed, and a pressure chamber 19 is formed inside the cylinder 16.

A ring 20 and a cover 21 with a Kolychev groove 22 are attached to the shell 14, and the protrusion 23 of the membrane 17 is located. The membrane 17 is filled with: a central hole 24 through which the increased pressure chamber 19 communicates with the pressure relief chamber 25 formed by the cover 21 and the membrane 17 The cover 2 is made with an axial bore 26, and along the axis of the cover on its outer sealing surface, housings 27 and 28 and a cover plate 29 are fixed in series. Elastic rubber membranes 30 and 3 are located between the housings 27 and 28 and the casing 28 and closing pin 29. 1. The housing 27 forms a ventilation chamber 32, which, with a hole 33 formed on the side surface of the housing 27, communicates with the atmosphere and a central opening 34 -. pressure equalization chamber 25. The diaphragm 30 is made with a bore hole 35, Case 28 is complete with a central hole 36 and a side hole 37. Plate 29 is provided with an inlet hole 38 to which the fluid element 39 is connected.

The device works as follows.

In order to maintain the air pressure created by the compressed air source, the membrane G / fits tightly against the valve seat 3, which is made on the cylinder 16 and locks the plenum chamber 19. The membrane 17 is in the closed position if the compressed air passes from the pressure chamber through the opening 24 into the pressure equalization chamber 25. If the chambers 19 and 25 have the same pressure, then the membrane 17 of the pressure equalization chamber has significantly larger surfaces than the membrane of the high pressure chamber.

In order for the pressure in the pressure equalization chamber not to fall, the membrane 31 must be pressed against the opening 36 and close tightly with a pulse from a fluid element having one stable position. Due to this, the air from the pressure equalization chamber can pass through the opening 35 to the membrane 30. Air enclosed between the membranes 30 and 31 presses the membrane 30 to the opening 34 and closes it.

In order to release the control conduit 12 from air, the long-lasting signal of the liquid element 39 to the membrane 31 is interrupted, as a result of which it blocks the opening 36. Thanks to this, the pressure of the air enclosed behind the membrane 30 drops as it comes out through the holes 36 and 37. As a result of this pressure drop, the overpressure in chamber 25 raises

the membrane 30 from the opening 34, and the air enclosed in the pressure equalization chamber 25 comes out through the opening 34 in the ventilation 32 and through the hole in the side surface of the housing 27 to the outside. If the pressure in the pressure equalization chamber 25 drops, then the membrane 17 overlaps the axial hole, exited in the lid 21, and the compressed air passes from the increased chamber to the pressure and 19 into the chamber 18 and out of it through the holes 15

out.

Due to the fact that a continuous signal acts through the inlet 38 to the membrane 31, it closes the hole 36, the outgoing air from the plenum W through the holes 24 and 35 suddenly stops its passage through these holes, presses the diaphragm 30 to the hole 34 and grinds it . This process is repeated with the membrane 17, which is pressed against the valve seat 13, which is filled on the cylinder 16 and thereby closes the pressure chamber 19 again.

The pipe 8 passes through the partition 2 forms with it a channel 9, through which the purge air enters the filtering sleeves 7. The pipe 8 is filled with a Kolychev ledge 40, which serves

a seat for an annular inflatable valve formed by the female 10 and the elastic material 11 placed on the partition 2 on the chamber side of the exhausted air. Babis 10 is made with a concave surface facing the annular

the protrusion of the pipe 8. On the babyshka there is a reinforced elastic material 11 attached to the concave surface of the babyshka during the push of the purge air. In woman 10, a channel is connected that is connected to pipeline 12.

compressed air nozzles 41.

If the membrane 17 locks the plenum chamber due to the effect of a pulse on the membrane 31 produced by the liquid element 39, then an increased pressure occurs in the pipe 12, which spreads through the nozzles and channels of the babyshka 10, as a result of which

elastic material is pressed against the ring

on pipe 8 and close channel 9. If

the impulse of the fluidic element ceases

the action on the membrane 31, then the pressure in the pipes connecting the compressed air pipe to the channel of the babies 10, drops, and a blow of the purge air occurs.

Depending on the length of the Sh1zhnaya part of the pipe 8, which can be made of different lengths, and from

rim lengths on which the tops are reinforced

filter sleeves, you can get a push of compressed air of various sizes.
