U1: Claim 1. The invention relates to the purification of gases from dispersed particles with devices with a fluent filtering material, which is movable during the filtration process, and provides for the purification of gases from gaseous harmful impurities. The purpose of the invention is to expand the field of application, for example for trapping gaseous harmful substances. FIG. 1 shows a longitudinal dust collector; FIG. 2 is a section A-A in FIG. one; FIG. 3 is a section BB in FIG. 1. The dust collector contains filtering elements consisting of sections 1 and 2 for trapping solid and gaseous impurities, respectively, fixedly mounted on supports 3 branch pipe 4 of the contaminated inlet port and branch pipe 5 of the exit of purified gases, containers 6 and 7 placed on the conveyor belt 8 and moving around the periphery of the dust collector. Section 1 is bounded by perforated partitions. 9 and 10, and the vertical partitions 11 are divided into cells 12 filled with granular material 13. The cells 12 in their lower part are provided with openings 14 with closures 15d of batch output of contaminated filtering granular material 13 into the container 6, where it is regenerated. Dust separated from the filtering material {13 material 13 is discharged into the hopper 16 (pos. D). The upper part of the filtering element 1 has an opening for the entry of dust-free granular material 13 (pos., P). Section 2 is limited by perforated partitions 10. and 17, and by vertical partitions 1B is divided into cells 19 filled with granular material 20 (for example, rubber balls) whose grains are coated with a layer 21 of a chemical reagent, i.e. chemically active substance in relation to neutralized gases. Each cell 19 in its lower part has an opening 22 for the exit of contaminated granular material, in which a pressure device 23 is located, consisting of a cam 25 placed on ea.ity 24, a stem 26 and a movable plate 27. Each hole 552 of the wall 22 is provided with a shutter 28 for batch release of the filtering material 20 into the container 7, in which the gaseous impurities formed during the neutralization process are separated from the granular filler. To collect this sediment, the dust collector is equipped with a hopper 29. A new coating is applied to the surface of the grains of filter material 20 by wetting it in the bath 30 with a solution of a chemical reagent. The upper part of the filter element 2 has an opening for the entrance of the next portion of the regenerated granular material 20. The dust collector operates as follows. Fluid and gaseous impurities air flow through the pipe 4 enters section 1, where it is cleaned of dust, the passage through the layer of granular material 13. The gas cleaned of dust is sent to section 2, where it collects harmful gaseous impurities, chemical reagent, deposited on the surface of the grains of the filter material 20. As a result of the interaction of the gas with the reagent on the grains, a layer of sediment is formed. The gas purified from harmful impurities is emitted into the atmosphere. . When the filtering material 20 passes through from 22 version 22, it is subjected to short-term deformation by the pressing device 23, as a result of which the sediment formed on the surface of the grains is destroyed. When the conveyor 8 is moving, the containers 6 and 7 fixed on it move in such a way that they are consistently aligned with one of the outlet openings 14 and 22, while the closures 15 and 28 are opened, releasing portions of filter material 13 and 20 containing containers in containers 6 and 7 or products of neutralization of gases, where they are separated from the filter material 13 and 20. By successively releasing the filter material 13 and 20 in portions from all the cells 12 and 19, each of the containers 6 and 7 discharges the collected products respectively into the bun EASURES 16 and 30 (position 1). 3 The granular material 20 in the container 7 is subsequently lowered into the chemical solution in the van 30 ((c (). When the extreme upper position is reached, the containers 6 and 7 are rotated 90. The filter material 13 and 20 contained in them is poured into sections 1 and 2, uniformly filling the volume of the upper part of the cells 12 and 19 freed from the grains (pos. P and W). 54 IIpi further their movement containers 6 and 7 occupy the lowest position, and the whole process of regeneration of the filter material 13 and 20 repeats Each section 1 and 2 is supplied with one or carried as many individual containers 6 and 7, the number of which is predetermined by the concentrations and properties of harmful substances in the gases to be cleaned, and the number of sections by their qualitative composition.
