CONICAL JET SCRUBBER WITH VORTEX SPRAYER Russian patent published in 2018 - IPC B01D47/00 

FIELD: dust collection equipment.

SUBSTANCE: present invention relates to wet dust collection and can be used in chemical, textile, food, light and other industries for purification of gases. In a conical nozzle scrubber with a vortex sprayer containing a housing with nozzles for dusty and clean gas, a nozzle spraying device, supporting and restrictive plates, between which the nozzle is located, a splatcher made in the form of a nozzle layer located between the supporting and restricting trays, and a device for removing slurry, the support plates being elastic, the nozzle positioned above the lower support plate is made of resilient materials, for example in the form of polyethylene balls, and a vibrator is mounted on the lower support plate, the nozzle is made in the form of hollow balls, on the spherical surface of which a screw groove is cut, or the nozzle is made in the form of a screw line formed on a spherical surface and having a profile like a circle, polygon, "Berl saddle" or "Itallox" saddle in the section perpendicular to the screw line, spraying device comprises a hollow cylindrical body, in the upper part of which an external thread is made for connection of a distribution pipeline for supplying liquid to fitting, and in the lower part of the body, an external thread is made for connection with a divergent vortex flow, the body has an inner cylindrical chamber which serves to supply liquid, in a cylindrical chamber, coaxially with it, a swirler is installed with a clearance relative to the inner side surface of the chamber, and the vortex flow dissector is fixed to the body by means of a casing having an internal thread and made in the form of a ring to which two diametrically located vertical plates are attached, connected in the lower part by a horizontally arranged rod, in the middle of which there is a second swirler made in the form of a disk with helical blades, embracing the rod in its middle part with a clearance and having stops at the edges in the form of disks arranged perpendicular to the rod, and in the cylindrical chamber, a hollow conical swirler is coaxially installed with a gap with respect to the inner lateral surface of the chamber, made in the form of a conical surface with a screw through thread, the vertex of the conical surface of the hollow conical swirl is fixed to the end surface of the rod.

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