FIELD: technological processes.

SUBSTANCE: invention is intended for fluid and gas treatment in chemical, oil-processing and other industries. Filter includes cylindrical case with treated medium inlet jet and mechanical admixture outlet jet, removable coaxial filtering cartridge, tubular filtering element with external filtering surface comprised by slotted grids in the form of cylindrical spiral made of precise V-shaped profile. One end of filtering cartridge is fixed in a pipe, while the other end is fixed in a fairing. Mechanical admixture outlet jet is connected to a mud box with drain jet. A baffling mesh is installed between the mechanical admixture outlet jet and mud box. A vortex chamber with flow swirler in the form of blades installed stationary inside the vortex chamber tube is connected to the case. Blade tilt angle ensures the optimum conditions for continuous flow along the blade contour.

EFFECT: simplified construction and increased filter capacity and life time.
