MESH VERTICAL FILTER Russian patent published in 2018 - IPC B01D47/06 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the wet dust collection technique and can be used in the chemical, textile, food, light and other industries. Mesh vertical filter comprising a housing mounted on the cover of the vapor-dust mixture source, an inlet and an outlet pipe, a filter element in the form of a rotating rotor having the form of an exponential rotation and made of two stainless mesh irrigated with nozzles, a sludge tray and an irrigated filter zone in the form of a coaxial cylindrical shell, the nozzles are in the form of vortex nozzles, each of which comprises a hollow cylindrical body with an external thread for connection to the connection of a distribution pipeline for supplying liquid, and fixed in the lower part of the body, a cap nut with a fluid flow divider, in which, in a casing, coaxial with it, a cylindrical hole is made, in the upper part of which a screen filter is installed, and in the lower part there is a throttle washer with a nozzle and a divider, the liquid flow splitter is attached to the end face of the union nut and is of the bar type in the form of a truncated tetrahedron fixed to the end face of the union nut, the ribs of which are rods with fixed blades with stops so that there is a possibility of their rotation from the streams emanating from the throttle washer with the jet of the nozzle, while the edges of the tetrahedron base are also connected by rods with fixed blades and stops, and a diffuser is attached to the surface of the intersection of the end surface of the union nut with its outer surface, covering with its lateral conical surface the divider of the liquid flow, while the outlet of the diffuser is below the base of the truncated tetrahedron, and the outlet itself is connected to an additional divider in the form of a circular perforated plate perpendicular to the axis of the diffuser, with a screened dome element attached to the perforated plate with a vertex directed away from the nozzle of the nozzle, and the cavity of this element is filled with a porous material, for example a wire of the "knuckle" type, and is axisymmetric to the outlet of the diffuser, to a circular perforated plate of an additional divider, in its central part, there is attached a central cylindrical atomizer, made in the form of a cylindrical shell, the solid part of which is located in the mesh dome element, the cavity of which is filled with a porous material, and the perforated part of the cylindrical sprayer extends beyond the mesh dome element.

EFFECT: increased efficiency and reliability of the dust collection process by increasing the liquid spraying rate of injectors.
