MESH VERTICAL FILTER Russian patent published in 2018 - IPC B01D35/00 

FIELD: dust collection equipment.

SUBSTANCE: invention relates to the wet dust collection technique and can be used in the chemical, textile, food, light and other industries. In a mesh vertical filter containing a housing installed on the cover of a vapor-dust mixture source, the inlet and outlet nozzles, a filter element in the form of a rotating rotor having the form of an exponential of revolution and made of two stainless meshes irrigated with injectors, a slurry tray and an irrigated filter zone in the form of a coaxial cylindrical shell, each of the nozzles comprises a housing with a swirl chamber and a nozzle, the body is made in the form of the supply fitting with the central opening and is rigidly connected to it and with the coaxial cylindrical sleeve with an internal thread and an expansion chamber, which is coaxial to the body, the nozzle, which is in the form of an inverted cup, is connected to the sleeve by means of a thread at its lower part, in the bottom of which there is a turbulent swirler of the liquid flow with at least two inclusions to the axis of the nozzle in the form of cylindrical openings, which are located in the end surface of the nozzle, where also a central cylindrical throttle opening is made connected to the nozzle mixing chamber, in series connected to the diffuser outlet chamber, and in the lower part of the mixing chamber of the nozzle a hollow conical swirler is fixed, its conical shell is fixed by means of at least three spokes fixed at one end to the conical shell of the swirler in its upper part, and the other end – in the annular groove made on the inner surface of the mixing chamber, and on the outer surface of the hollow conical swirler a screw cutting is made.

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