    An air purifier intended for use, e.g., as a grease filter in air venting systems. The purifier comprises a plurality of modules operating according to centrifugal separation, each module comprising at least one vortex chamber. Gas flow entering the vortex chamber is set into helical motion therewithin, such that the gas flows through the vortex chamber in a single direction, substantially perpendicular to a direction in which the incoming gas flow is introduced into the module.

    WITH
    ; The invention relates to a device for cleaning the air and a purpose for using, for example, as a grease filter in a cart. , spiritual systems of kitchens, institutions and other premises.
    The aim of the invention is to increase productivity and degree of purification.
    FIG. 1 shows an air cleaner, a general view; FIG. 2 - the same, side view; in fig. 3 is the same, top view: in FIG. 4 - section aa on
    FIG. 1 (module)
    The air cleaner contains a cleaning part made of parallel air cleaning modules 1 separated by partitions 2 into cells 3 with inlet openings through which the air flow spirals perpendicular to the cross section of the cells. Cells 3 are provided with partitions 4 and 5, one of which (partition 4) divides them into two interconnected vortex chambers in which the air flows have the opposite direction of rotation
    15
    camp 4. Purified air exits both the bottom and the top of the air cleaner, and contaminants are discharged from the inside surfaces of the chambers along the grooves (not shown). If the incoming air flow reaches the center line of the device, then the purified air comes out from below, if the incoming air flow is higher, then the purified flow comes out from above. The force driving the air flow in the air cleaner depends on the pressure drop used by the fan or other blowing device.
    In the proposed air cleaner, highly efficient separation with relatively low air flow rates is provided, the separation degree of particles larger than 5 microns is about 95%, and the degree of separation of particles smaller than 5 microns.
    25 cBbmie 2.5 microns - about 50%.

    Claims (2)
    [1]
    1. An air cleaner, including a cleaning part with a frame, partition 5 is installed at the inlet-30, which is filled from parallel air holes with the formation of narrowing-cleaning modules, separated
    forceps along the flow of the channel, the channel width in narrow parts is less than 10 mm, preferably 9-8 mm.
    The air cleaner has a frame in the form of cuffs 6.7 and handles 8. The cells of the 3 modules are connected to each other using element 9 using any known method of fastening
    The air cleaner works as follows.
    The air containing contaminants flows through the inlets to the cells 3 of the cleaning part of the air cleaner. The contaminants are thrown against the walls of the vortex chambers up to the partitions 4. Then the direction of rotation of the flow is reversed and the contaminants are collected against the walls of the cells 3 after overflow.
    camp 4. Purified air exits both the bottom and the top of the air cleaner, and contaminants are discharged from the inside surfaces of the chambers along the grooves (not shown). If the incoming air flow reaches the center line of the device, then the purified air comes out from below, if the incoming air flow is higher, then the purified flow comes out from above. The force driving the air flow in the air cleaner depends on the differential pressure used by the fan or other blowing device.
    In the proposed air cleaner, a highly efficient separation with relatively low air flow rates is provided, the degree of separation of particles with a particle size exceeding 5 µm is about 95%, and the degree of separation of particles with a particle size
    cBbmie 2,5 microns - about 50%.
    Invention Formula
    cell dividers with inlet openings through which the air flow passes in a spiral perpendicular to the cross section of the cells, characterized in that, in order to increase productivity and cleaning, the cells are equipped with partitions, one of which divides them into two communicating with each other vortex chambers in which air flows have the opposite direction of rotation, and a friend is installed at the inlet to form a channel that narrows in the direction of flow.
    [2]
    2. The air cleaner according to claim 1, characterized in that the channel width in the narrow part is less than iO mm, preferably 3-8 mm.
