FIG. 1 shows the proposed device, a cross-section; in fig. 2 shows section A-A in FIG. one.

The housing of the device consists of two displaced relative to the axis of the settler 8 on coaxial integral parts: cylindrical - angle of 30-40 ° in the direction of swirling flow.

In this case, the ratio of the dimensions of the settling tank 8 to the radius of the chamber of the inertial step is

inertial stage 1 (Fig. 1 and 2) of a larger diameter and contact chamber 2 (Fig. 2) of a smaller diameter. A filter element 3 is placed coaxially in the internal cavity of the housing;

 (0.3-0.35) g, where h is the height;

b - 1/2 sump width; 1 is the length of the opening for removal of particles; g is the radius of the chamber of the inertial step. The device works as follows. Fluid is supplied to the device through the input tangential nozzle 18. In the inertial stage 1, the fluid flow is swirled along the narrowing channel 6 and its increase

fluid inertial steps and safety speeds. At the same time, under the action of its centering from premature wear and disintegrating forces, heavier solid particles of destruction are removed from the fluid to the periphery to the cylindrical wall of step 1 and at the end of the channel b through the transverse opening 7 and the pocket 9 enter the sump 8 . 35 At the same time, the spiral protective screen 5, covering the filtering element 3, protects it from mechanical action of particles and at the same time is an element of channel 6 in the process of inertia and the edge of element 10. Due to this, 40 liquid cleaning.

A separating element 14 is formed in the cavity of the settling tank 8, the bent vocal zone of the sludge, which keeps it inward, prevents the captured particles from passing away from leaching and removal of inertia particles of destruction with the flow of their liquid to the filtering fluid 3. Filter element 3 . The withdrawal element 10 contributes to the upper part of the stage 1, which is provided with a water –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– ezhnoy liquid on the grid.

after the contact stage of cleaning, the speed at the realized speed will come to the connection through the axial aperture of the subconnect stage of cleaning. A flange 12 is placed coaxially from the step 1 and the curved edges of the element 14 and the screen 5 through the annular channel 20 into the internal cavity of chamber 2 through the filter element 3. At the stage

Poured into openings in opposite flanges. The filtering element 3 can be made of a cellular or woven mesh, the rigidity of which is provided by a skeleton mesh 4. In the inertial step 1, a spiral protective screen 5 is placed and rigidly connected with its lateral 25. walls and the inner walls of the inertial step 1 (Fig. 1) covers the surface of the filter element on the twist angle of the flow

The axis of the opening 7 is offset relative to the axis of the sump in the direction of flow swirl by angle p (Fig. ). The sump 8 has a pocket 9 between the inner stencil lid 13 for mounting and dismounting the filter element 3. Corresponding inner and outer folds of the shell ends of the chamber 2 form a separating element 14 at the opening 7 for separating solid particles from the stream and a diverting element 10 for removing solid particles in the suction zone through the pocket 9
