f 0 I1 The invention relates to apparatuses of chemical technology and can be used in the chemical petrochemical and other industrial sectors for the simultaneous purification of gases from aerosols and chemical components. A device for air purification is known, which contains a closed perforated belt stretched between the drums, which are at some distance from each other, and one drum is surplus and contains brush-type engaging elements. The tape is moved by means of a water turbine, the shaft of which connected to the drive shaft :, with the dirt particles being washed off from the belt by a stream of water leaving the turbine 1J. However, the gaseous chemical components are trapped by the device inefficiently. In addition, it is difficult to perform, and the liquid consumption for washing particles from the tape is relatively high. The closest to the proposed technical essence and the achieved effect is a gas cleaning device comprising a housing with a steam pipe divided into cleaning and regeneration chambers arranged perpendicular to the flow of the gas plate, which are maintained and periodically moved by an endless belt with filtering material controlled pressure switch. End plates along the tape plate is always partially clogged, which facilitates the filtering of small particles. The spring-loaded plates, perpendicular to the tape, fold and abruptly return to their original position, page hiva. C2J. The disadvantages of the known device are the low efficiency of trapping gaseous chemical components from the gas to be purified, the difficulty of removing particles from moist gas due to particles sticking to the plates that may not bounce off them when shaken, as well as the difficulty of using liquid trapping devices. aggressive aerosols (for example, aerosols of acids) due to failure of the springs. The purpose of the invention is to improve the cleaning efficiency from chemical gaseous impurities. A2 This goal is achieved by the fact that in a known gas purification device comprising a housing with inlet and outlet nozzles divided into purification and regeneration chambers, an endless belt with a drive mounted inside the housing, equipped with filter material and plates installed on it, Astins' plates are provided with a layer of fibrous material and bundles of fibers in the form of filaments and brushes, with the upper edge of each plate having an L-shape, bundles of filaments in the form of filaments are installed on it in front of the layer m of fibrous material along the course of the gas stream being cleaned, the fiber bundles in the form of brushes are located along the perimeter of the plates, and the upper part of the body is equipped with dispersing agent. FIG. 1 shows a device, a section J-in FIG. 2 is a view of FIG. one; in fig. 3 shows the node I in FIG. one; in fig. 4 plate, side view; in fig. 5 - version of the execution with the location of the flat. Steen on the winchester shaft. The gas cleaning device consists of a housing 1, divided into a gas cleaning chamber 2 and a regeneration chamber 3 and equipped with inlets 4 and outlet 5 of a gas to be treated. Inside the housing 1, an endless belt 6 is mounted horizontally with a lead 7 and driven 8 shafts. Tape 6 is equipped with a fibrous filter material. Plates 9 with grids 10 are installed perpendicular to the filter belt. In accordance with an embodiment, plates 9 with grids 10 can be mounted on a drive shaft 7. In both cases, the upper part of the contactless tape 6 and the leading 7 shaft is in the gas cleaning chamber 2 and the bottom is in the regeneration chamber 3 filled with the regeneration solution. The horizontal arrangement of the endless belt 6 is provided by the rollers 11. The plates 9 with the grids 10 are provided with one or two layers of fibrous filter material 12, which quality is MG.NUT PIM (-P) YAT.SYa is a nonwoven fabric of syngetics and artificiality

The top edge of the plates 9 is L-shaped, equipped with a core element 13, made in the form of a corrugated or perforated tube, and bundles of monofilament fibers 14, the lower free ends of which touch the endless belt 6 or the drive shaft 7. The fiber bundles 9 are located along the perimeter of the plates 9 15, made in the form of ilieTOK.

Dispersing devices 16 are located in the upper part of the housing 1. The housing 1 also has a nozzle 17 for discharging the regenerating solution. The device contains a drive 18.

The device works as follows.

The gas to be cleaned through the inlet 4 enters the gas purification chamber 2 and is cleaned of toxic substances when plates 9 with grids 10 and filter material 12 are placed on them. On top, through dispersing devices 16 installed in the upper part of housing 1, plates 10 are fed regenerating solution. Since the perimeter of the plates 9 are arranged for launches of fibers 15, made in the form of brushes, this ensures leaktightness when gas passes through the installation and thereby prevents the penetration of chemical impurities contained in the gas to be cleaned. The upper edge of the plates is L-shaped and is equipped with bundles of fibers 14 fixed on the core element 13, with a length that allows the ends of the fibers to touch the endless belt 6 or the drive shaft 7, which allows for additional gas cleaning, namely not to get

large particles in the filter 9 {th elephant. 12, as well as effective filter regeneration of filter installations. Particles of organic 5 substances, usually present in the gases to be cleaned and clogging the fibrous material, are also deposited on fibers 1D. The endless belt 6, equipped with a fibrous filter material, is driven by a drive 18, a follower 8 and a driving shaft 9 and the rollers 11 in a direction opposite to the flow of the gas to be purified or along the gas flow. In the second case, the speed of movement of the endless belt must be less than the flow rate of the gas to be purified. The plates 9 are moved together with the tape 6 into the lower part of the housing 1 into the regeneration chamber 3, where the filter elements 14 of the plates 9 and the belts 6 are cleaned of aerosols deposited on them and other chemical impurities. The free turning of the bundles of fibers 14 contributes to their better cleaning. The cleaned gas is directed through atmosphere 5 to the atmosphere. As necessary, the regenerating solution is discharged from the housing through the nozzle 17.

The use of the invention will make it possible to almost completely capture aerosols and chemical gaseous components. In this case, the fibrous material is well regenerated by passing through the regenerating solution.

The device works continuously, installation and disassembly is simple.

The invention may also be applied in the transportation of suspension powders, cakes, and other products that produce toxic substances in the form of aerosols or gases.
