Filter device. The device relates to filters for cleaning liquids and gases, can be used in hydro - and pneumatic drives, in water, oil and gas purification systems. A filter device is known (US Pat. No. 4,481,022), in which filter gas is supplied inside a bag filter with one end plugged. The disadvantage of this device is that it does not use a fairly large internal volume of the sleeve to increase the filtration area, reduce hydraulic resistance, specific dimensions and weight. A filtering device is known (German patent DE3225442 C2), in which a bagged filtering material with one blind end is located on a perforated cylinder. This device has the same disadvantages as the above device (prototype). The purpose of the proposed device is to increase the performance and dirt capacity of the filter, the duration of its operation to allowable pollution, less hydraulic resistance, energy consumption, specific dimensions and dimensions, manufacturing and maintenance costs due to an even larger increase in the filter surface without increasing the dimensions of the filter. This goal is achieved by the fact that cylinders of different diameters with longitudinal channels for exiting the purified liquid (gas) are coaxially mounted in the filtering module, and the filtering material of corresponding diameters is installed on the external and internal surfaces of the cylinders, forming a gap between them for dirty liquid (gas) to enter ) Figure 1 shows a schematic section of a filter; figure 2 is a section of a filter module with a filter sleeve; in Fig.Z - a filter module, f of which the second end of the sleeve is sealed with a washer; in Fig.4 a filter module with two coaxially arranged cylinders of different diameters; in FIG. 5 - filter with one filtering unit with a dirty supply and clean liquid (gas) discharge through the cover; Fig.6 is a sectional view of a filter with a filter sleeve and bulk filter material; Fig.7 is a sectional view of a filter module with pleated filter cartridges; on Fig - section of a filter with cylinders of two perforated pipes of different diameters; Fig.9 is a sectional view of a filter in which cylinders are connected to a housing. The filter (figure 1) consists of a housing 1, a cover 2, filter modules 3, a pollution indicator 4, a safety device 5. The filter module (figure 2) consists of a cover 6 with channels for the removal of purified liquid (gas), to which the cylinder is connected 7, filter material 8 in the shape of a sleeve. The filter sleeve 8 covers the outer and inner surfaces of the cylinder. The cylinder 7 has the required thickness and longitudinal slots, which serve as channels for the removal of purified liquid (gas). One end of the filter sleeve is fixed in the area of the cylinder with the module cover, and the other end of the sleeve can be deaf (Fig. 2) or plugged with washer 11 (Fig. 3). The cylinders of the filter module can be made of two perforated pipes 9 and 10 (Fig. 3) of different diameters with round, longitudinal or transverse holes on their surfaces for the passage of purified liquid (gas), from gratings or nets. The ends of the perforated pipes are connected directly to each other or by means of a ring 12. To increase the rigidity of such a cylinder, stiffeners 13 are installed between the perforated pipes 9 and 10 (corrugated tape, tube strips, rings). On the cover of the filter module (Fig. 4), a cylinder 15 of smaller diameter with channels for the passage of purified liquid (gas) is installed, on the surface of which a filter sleeve is located. The cylinder 15 can be connected to the ring 14 (Fig. 5 and 6), which is fixed to the cylinder 7. Similarly, using the rings, you can install a third and other cylinders. The cylinders can be connected to the cover of the module 6 and the ring 14 rigidly (Fig.4,6) or through a detachable connection (Fig.5). The filter module (Fig. 7) consists of a cover 6, cylinders 7 of different diameters with longitudinal channels for the exit of a very fine liquid (gas), filter material 18, rings If /, which are connected to each other by a cylinder 7 and form a space for an exit of a very fine liquid (gas) , rings 9, having a detachable connection with the cylinders 7 and fixing the axial position of the filter material 18. In the presence of water shocks, pulsations and increased pressure of the liquid (gas) to prevent the filter material from being pushed through the holes and cuts of the cylinders 7 n their surfaces can be installed grid 16. The cylinders 7 can be joined to krypzhoy (7 and 8) or with the housing 1 (Figure 9). Inlet and outlet of the gas liquid can be performed through the housing and the cover. The filter material 18 can be made of corrugated cartridges (Fig. 7) or in the form of cartridges (Figs. 8 and 9) of a wound filter cloth or threads, porous plastic or ceramic, which increases the filter surface, and therefore the throughput, dirt capacity and duration work to acceptable pollution, reduce hydraulic resistance, energy consumption, specific

dimensions and weight indicators, manufacturing and maintenance costs. The filter material can be made of several layers with a decrease in the size of the cells along the liquid (gas).

To ensure the normal flow of dirty liquid (gas) to the filter elements, the distance between the inner surface of the larger cylinder and the outer surface of the smaller cylinder is determined by the formula

 + T2 + h

where: T / and T are the thicknesses of two adjacent filter elements;

h (l t 100) mm - the gap between these filter elements. Large clearance values correspond to large diameters.

In the filter with one filter module (Figs. 5, 6, 8 and 9), its cover acts as a filter cover. The supply and removal of liquid (gas) can be performed both through the cover and through the filter housing.

The proposed device operates as follows. Dirty liquid (gas) is fed into the filter, it enters the space between the filtering materials 8.18 and the housing 1, passes through the pores of the filtering material, openings and channels in the cylinders 7 and leaves the filter. During the regeneration of the filter material, the inlet and outlet of the liquid (gas) are reversed.

Using the proposed device allows two or more times to increase the performance and dirt capacity of the filter, the duration of its operation to allowable pollution, reduce hydraulic resistance, energy consumption, specific indicators of dimensions and weight, manufacturing and maintenance costs.
