    A crossflow wall for a gas stream has baffle elements which form inlet ducts, which narrow in the inflow direction, and end in a steadying bead. Coaxially to the baffle elements, concave impingement surfaces are arranged which are staggered relative to the baffle elements and are curved at a distance around the steadying bead thereof, so that they deflect the gas stream to the rear of the baffle elements. The baffle elements and impingement surfaces are of at least approximately rotationally symmetrical shape and are arranged with pairs of them having parallel axes. Between the impingement surfaces, outlet ducts are left free, through which the gas stream leaves at least approximately parallel to the inflow direction. The heavy foreign matter particles accumulating in the vicinity of the impingement surface are collected in the peripheral edge of the impingement surface by a collecting channel, are passed into a collecting chamber and extracted.

    This invention relates to devices for separating impurities from a gas stream.
    The purpose of the invention is to increase the efficiency of the device.
    1 shows a device for separating the impurities from the air stream, a vertical axial section; figure 2 is a view along arrow A in figure 1; figure 3 is a view along arrow B in figure 1; 4 and 5, the device, embodiment, vertical axial section; Figure 6 is the same with the ducts for heat and coolant of Figure 5; FIG. 7 shows a device for dryly collecting piquid impurities from the air flow, and FIG. 5; on Fig - section bb In figure 7; in fig. 9-11 - three working phases; 12 shows the process of separating impurities.
    The device comprises a square {(in plan) case 1 of sheet metal, preferably stainless steel sheet. On the front side of case I, a square plate 2 is fixed, also made of stainless sheet steel. On plate 2 there are funnel-shaped guide bodies 3, each of which restricts one inlet 4 for gas. Each of the guide bodies 3 is rotationally symmetric about the axis, made in the form of a Venturi tube 5 and ends with a ring-shaped soothing lip 6. The axes of the guide bodies are arranged mutually in parallel with equal intervals. Behind each Venturi tube 5 on one axis there is a concave bump 7 with an annular peripheral edge 8 that covers the back side of the corresponding guide body 3 at a radial distance almost equal to the radial distance between the soothing protrusion 6 of the same guide body 3 and the cone-shaped an axial 9-flow distributor located in the center of the baffle 7. Between the baffle 7 and the outer wall of the guide body 3 there is an annular bore 10. The soothing lug 6 has This is the same bend as the opposite of the bump 7. Each of the bump 7 has an axial bore 11 and rests on its back side
    on support 12 of heat and sound insulating material, for example rigid polyurethane foam, through which hole 11 passes through.
    The rear side of each support 12 is made of a single axle 13, which enters into the front of the support ring 14 made of metal and is fixed thereto with a slotted locking ring 5 made of synthetic material. The support rings 14, together with the spacers 16, mounted on the housing 10, form a supporting structure in the form of a grid that holds the supports 12 at intervals such that around each support 12 there remains a free exit channel 17 for gas. Around each bump 7 on the same axis with it there is a collecting chamber 18, provided with an annular
    the catching element 19c is a curved end 20 placed between the soothing protrusion 6 and the peripheral edge 8 of the bump 7 at a distance from the latter and forming with it a discharge channel 21 for impurities. The nozzle 22 of the collecting chamber 18 is connected to an exhaust fan ((not shown).
    In the device pictured on
    4 and 5, in the axial bore 11
    there is a pipe 23 for the liquid, which in the flow distributor 9 ends with a nozzle 24. On the same axis with the inlet pipe 23 in the opening 11 there is another pipe 25 of compressed air, at the end of which there is a ring-shaped nozzle 26. There is a conical cap .27,
    reinforced in the distributor 9 flow. The conical cap 27 is placed with a gap in relation to the surface of the distributor 9 flow.
    The device works as follows.
    in a way.
    The air, which must be cleaned, for example, from particles of dust and grease, passes in the direction of arrow A (Fig. 1) and enters the inlet ducts 4, in
    which he accelerates. Compressed air entering through the pipeline 25 exits the nozzle 26 with a sharp annular jet and finely sprays the liquid leaving the nozzle 24 into

    reflected gas stream. Particles of dust and grease accumulate on droplets of liquid, then deposited on the bump 7, along it are transferred 3 air flow mostly radially outward and caught by the curved end 20 of the ring-shaped catching element 19, entering through the discharge channel 21 into the collecting chamber 18, and leaving through pipe 22 or depending on the rheological properties or the volume of impurities precipitated from the air — they are pulled out at a more or less significant vacuum. Air escapes through the outlet channel I7 or through a closed loop back to the place where it was polluted with impurities. The device of FIG. 6 differs from the device of FIGS. 1-5 in that the baffle 7 rests on the support 12 not directly, but through the intermediate wall 28 and the rear wall 29 Walls 28 and 29 have approximately the same shape as the baffle 7 and limit the channel 30 for heat or coolant. On supply line 31, coolant 9 is directed to channel 30, then passes on the inner side of baffle 7. Distally to the outside, it flows around the intermediate wall 28 and from its rear side to another line 32, which leads to the refrigeration unit (of known construction). The cooling of the baffle 7 allows the release of volatile impurities, for example solvents from air, due to the condensation effect. When using a hot medium, evaporation occurs. If the device is operating in the dry dust removal mode, this axial opening 11 can be closed with a stopper (Fig. 7 and 9). Screw ribs 33 impart rotational motion to the air flow, which additionally promotes the release of particles of liquid or dust from the air. The inner side of the guide organ.3 may also be equipped with similar ribs. The soothing protrusion 6 forms a lower 180 ° curved lower end section of the guide body adjacent to the outer surface of the guide body J4. The length of the pacifying protrusion 6, measured along its outer surface, is a fraction of that length of the bump 7 that runs from the center of the flow distributor 9 to the peripheral edge 8 of the bumper 7. The bend of the calming pivot 634 pa 6 is aligned with the bend of the bump 7 so that the radius i applied transversely to the gas flow over the greater part of the specified length of the chimney, concerns 6 chambers 7 and a soothing protrusion 6 places with approximately the same bend, in Fig. 12 designated by letter indices C and T. This is a mutual correspondence from ibov is maintained to the point E. Figure 12 impurity particles entrained in the gas stream, shown by broken lines, while the gas flow is indicated by arrows. The gas flow G is first strongly accelerated in the guide body 3, having the shape of a Venturi tube, then collides with the baffle 7 and calms down as the bias direction changes, and the heavier impurity particles are more and more concentrated near the baffle 7 and by means of the catching element 19 into the collecting chamber 18 and from there being drawn out. The distributor 9 flow with tip; NIKOM can be either under the entrance of the guide organ 3 (Fig.91, or go inside the guide organ 3 (Fig.10). The angle at the apex of the cone of the flow distributor 26 can be from 75 to 120 °. Claim 1.
