    One or more hollow tubular air channeling members (31, 31') are positioned in the interior of an internal collection type filter bag (20) to separate the incoming dirty air into a plurality of portions essentially confined from each other and to direct these separated and confined portions of dirty air to different interior portions of the filter bag and thereby increase the effective filtering efficiency of the filter bag and also increase useful bag life.

    专利说明:

    The invention relates to air cleaning devices for removing dust by filtering it through fabric filters and can be used in chemistry, energy and other industries.
    1 shows a General view of the device, the section; figure 2 - filtering sleeve, the cut; in fig.Z - the same, on an enlarged scale; 4 is the same in isometric; FIG. 3 shows the filtering hose according to FIG. A, in which for the sake of clarity, parts of the devices are shown spaced apart; figure 6 - section aa on fig.Z; FIG. 7 is a general view of an air distributor for transporting air with a conical partition according to FIG. 3 in an isometric view.
    The purpose of the invention is to increase the efficiency of air purification.
    The filtering device consists of a housing 1, in the lower part of which a support grid 2 is placed, forming a chamber 3 for injecting dusty air from which through openings
    4 filter bags 5 enters the dusty air in the filter bags
    5. The sleeves 5 are installed vertically with tension, with their lower condas secured in the openings 4 of the grille 2, and the upper ends are closed and led by, for example, springs to a horizontal frame (not shown) so as to support hands
    5V vertical and open position. The lower end of the sleeve 5 is fastened with the clip 6 in such a way that it is positioned around the opening 4 of the grill 2 and adjoins it. The sleeve is made of gas-permeable fabric of another material. The upper end of the sleeve 5, is closed by a cover 7 or a stopper, for which the sleeve 5 is suspended. The lower conductive, air distribution element 8 is spaced 1 (:
    in the lower part of the sleeve 5, and the upper air-conducting element 9 is located in the intermediate part of the sleeve 5 in such a way that it mates or is in telescopic interconnection with the lower element 8. Both elements 8 and 9 are hollow (preferably not perforated) and have enlarged Renny areas 10 and 11 at the upper end in the shape of a truncated cone, adjacent to the sleeve 5 tubular qilin

    drical parts 12 and 13 and cylindrical parts 14 and 15.
    When installing air-conducting elements 8 and 9 in the sleeve 5, the top element 9 is initially placed in the open end of the sleeve 5. The uppermost edge 16 of the cylindrical part 15 of the element 9 is tapered inward, as shown, to facilitate installation in the flexible sleeve 5. The cylindrical part 15 of the element 9 runs vertically, so that it can fit snugly to sleeve 5.
    The upper element 9 is located vertically in the sleeve 5 so as to pass approximately the middle third in the length of the filtering sleeve 5. The lower element 8 is located vertically in the sleeve 5 in a position below the upper element 9 and passes approximately the lower third of the sleeve A 5. In the extended section the lower element 8 by means of a mating or telescopically extending cylindrical part 13 of the upper element 9, while the cylindrical part 13 of the upper element 9 has a smaller diameter. and goes down into the cylindrical part 12 of the lower element 8. The cylindrical part 12 of the lower air-conducting element 8. can pass downwards just below the level of the grid 2. However, the lower end of the element 8 can end flush with or at the bottom of the grid 2 from conditions.
    The lower and upper connecting means 17 and 18 are used to hold the lower and upper element 8 and 9 in their respective desired positions. At the same time, the upper connecting means 18 contact with the interior of the expanded portion 10 of the lower conductive air element 8 and rest within it. The upper connecting means 18 are of such dimensions that the cylindrical part 13 of the upper element 9 enters them. In the same way, the lower connecting means 17 are placed along the perimeter of the hole 4 and are fixed on it, the cylindrical part 12 of the element 8 with the g rim 19 enters them, also in contact with and supported on the lower connecting means 17.
    The connecting means 17 and 18 may be the same by design.

    The operations usually take the form of a truncated cone frame for the free passage of air through them. In addition, a large lower end portion of the upper connecting means 8 is designed so as to ensure engagement to be located within the extended portion 10 of one of the jointly arranged air-conducting elements, i.e. element 8, while ensuring that the pipe and the engagement of the cylindrical part 13 of the other air-conducting element 9 enter and engage, thereby helping to preserve the air-conducting elements in the desired axial coincidence.
    It is advisable that the lower and upper elements 8 and 9 are constructed of stainless steel or another sufficiently strong and reliable material that satisfies the conditions of use. It is also desirable that the lower and upper connecting means 17 and 18 are constructed from a similar material. In the filter with a filter sleeve having a diameter equal to 300 mm and a length.

    sleeves A, B and C. The purified air enters the interstitial space of the housing 1, from where it is emitted into the atmosphere through the nozzle of the purified air. The dust that has settled on the inner surface of the sleeves, when regenerated by shaking and / or reverse blowing, is discharged into the hopper and removed from it through the gate.

    1; - A filtering device for air purification, comprising a housing with a support grille, on which vertical filtering sleeves with an internal filtration surface are attached, having open ends, which are equipped with devices installed inside the hose in order to increase the efficiency of air purification one or several tubular air distribution elements dividing the sleeve in height into areas of different lengths and having an extended section at the upper end, adjoin
    equal to 6 m, both the lower and the upper zoshy to the filtering sleeve.
    elements 8 and 9 have a length of about 2 m while the upper element 9 has a longer length due to its lower part 13, which should fit into the lower element 8. The enlarged upper parts of .10 and 11 elements 8. and 9 have the same diameter as and sleeve 5, typically about 300 mm. The diameter of the tube of the lower or the end element 8 is 200 mm, and the diameter of the body part of the upper element is 9-150 mm.
    The operation of the bag filter according to the invention is as follows.
    The dusty air enters through the inlet to the lower part of the housing 1 under the grill 2, in which filtering sleeves 5 open at the bottom are fixed. At the entrance to each sleeve, the air flow is divided into two or more parts, which are filtered through separate air-distributing elements 8 and 9 parts of filtering
