BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air separator consisting of a pressure vessel divided by two transverse partitions into an inlet, an outlet and a collecting space, wherein cyclons with tangential inlets of the polluted air into the cyclone separation chamber are provided.

Dust separators of this type operate on the principle of inertia forces acting on a curved path in the cyclone separation chamber. The individual cyclones form a compact, undetachable unit with the separator body. Cyclones are assembled into parallel connected systems - multicyclones. Air enters the cyclones tangentially through rectangular inlets. The air is rotated and the particles are separated in the separator chamber, which are thrown by the centrifugal forces on the wall of the cylindrical part and, due to gravity and the axial component of the entrainment movement, drop to the ejection port. Clean air flows through the outlet opening into the outlet space of the separator.

The impurities of this embodiment have the great disadvantage that the relatively narrow inlet openings of the cyclones are often sealed. This leads to a decrease in the performance of the separator and eventually to the decommissioning of the whole multicyclone. Because the cyclones are difficult to access and cannot be dismantled, cleaning the separator is very difficult and laborious. In addition, sometimes the contaminated air mass may contain coarser impurities, such as fabric pieces, rubber, etc., which will damage a cyclone whose repair inside the pressure vessel is very laborious.

The invention is based on this prior art, wherein the essence of the impurity separator according to the invention consists

-A-231 ββ | from the pressure vessel divided by two transverse partitions to the outlet, inlet and collecting space, where cyclones with tangential inlets of contaminated air mass into the cyclone separating chamber are arranged on the partition between the inlet and collecting space of the separator. there is provided a flange on the cyclone for its attachment in the through opening of the lower partition, wherein the cyclone outlet tube has one end located in the upper part of the separation part space and the other cone is inserted into a discharge tube which opens into the outlet space and is attached to the upper separator partition.

It is particularly advantageous that the two first rows of the discharge pipes are connected to each other by transverse and longitudinal reinforcements forming a lattice away from the inlet throat.

This arrangement eliminates all the disadvantages of the prior art separators. Individual cyclones can be easily dismantled and cleaned with sealed inlet openings or easily replaced damaged cyclones. A lattice made of longitudinal and transverse stiffeners catches coarse impurities and does not eliminate or even damage cyclones.

An exemplary embodiment is shown in the accompanying drawing, wherein FIG. 1 is a schematic longitudinal section of a cyclone; FIG.

3 shows a plan view of the lower separator partition. FIG.

The dirt separator consists of a cylindrical pressure vessel 11, which divides the two partition walls 3 into three spaces - an inlet space 6, an outlet space 16 and an outlet chamber 18. and collection space <6. The active part of the separator consists of a set of cyclones J arranged offset in the inlet space 4 of the separator and fixed to the lower partition by means of screws 46. The connection to the outlet space of the separator is made by a set of thick-walled discharge tubes 8 fixedly fixed in the upper partition 2. The connection of the discharge tubes 8 to the separating cyclones 7 is made by sliding and sealing with O-rings. The first two rows of the discharge pipes 8 are reinforced with each other by transverse and longitudinal stiffeners 9 so as to form a rigid unit and to avoid vibration in the inlet part due to the dynamic effects of the air stream.

The longitudinal stiffeners 2 are elongated and thereby create distribution channels for evenly distributing the air stream into the individual cyclone 7. In the inlet space 4 a manhole is formed which, together with the manhole in the collecting space 2, allows replacement or cleaning of individual cyclones 7 The cyclone separator 7 itself consists of a separation chamber 11 with two tangentially arranged inlets 13 of rectangular shape, an outlet tube 14 of the separating cylindrical part 15 with a narrowed dirt outlet opening. The separation part 15 is provided with a flange 10 for fastening the cyclone 7 to the bottom between the wall 3 by means of screws 16.

The air enters the separator through the inlet throat 12 and encounters a set of discharge pipes 8 where the distribution channels formed by the stiffeners 2 are evenly distributed throughout the cyclones 2. The transverse and longitudinal stiffeners 9 form a lattice that captures eventual coarse particles , which may enter the entrance space 4, so that they do not clog and thereby render part of the cyclones 7 out of operation.
