AIR LIFT VORTEX APPARATUS WITH PARABOLIC SWIRLER FOR WET GAS CLEANING Russian patent published in 2018 - IPC B04C5/23 

FIELD: technological processes.

SUBSTANCE: invention can be used in wet cleaners of gas outbursts used in chemical, oil and gas industries, etc. In an air lift vortex apparatus with a parabolic swirler for wet gas cleaning comprising a cylindrical chamber with an inlet pipe, a slurry flow pipe into the slurry tank, an axial sprinkler perforated along the entire length by small diameter holes and plugged from the outlet end, the cylindrical chamber is provided with a pair of swirlers installed in series, the first swirl in the course of the gas is rigidly fixed to the axial sprinkler, and the second swirler in the course of the gas is formed with a central hole and is connected to the walls of the cylindrical chamber, forming a gap for the passage of the gas flow to the central zone of the apparatus, the swirlers are made in the form of an elliptical paraboloid, the guide blades of which are curved along the helical surface and form curvilinear convergent ducts, cylindrical chamber is connected with the inclination to the cyclone by means of flanges and a branch pipe of tangential entry into the cyclone, with the withdrawal of dispersed particles is carried out by means of a pipe of the flow of slurry into the slurry tank of the apparatus, the cyclone is made in the form of a wet dust collecting apparatus, and in the tangential inlet to the cyclone there is installed a liquid inlet with a nozzle for flushing formed from the rotating gas-liquid flow of the mobile foam, and in the cyclone in the upper part of the housing an annular sprinkler with at least three nozzles is installed, connected by a pipeline to the liquid inlet for flushing out the mobile foam formed, while the purified gas flows through the exhaust pipe of the cyclone, and the sludge into the hopper to collect it from the cyclone, and then into the slurry tank.

EFFECT: increased effectiveness of dust and gas purification due to the organization of the rotational motion of the dust and gas flow, more efficient use of the action of centrifugal forces and use as a second, wet, phase dust and gas purification of a wet dust collector at the outlet of the apparatus, which as a whole makes it possible to increase the efficiency of the apparatus and improve the protection of the environment.
