GAS SCRUBBER Russian patent published in 2018 - IPC B01D47/04 B01D53/18 B05B1/34 

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. Gas scrubber comprises a body composed of upper and lower sections, a branch pipe for introducing a dusty gas, a branch pipe for the outlet of purified gas, a spray catcher with a centrifugal swirler and a branch pipe for draining liquid from the spray catcher, spraying device, plates with a stabilizer, a nozzle for periodically swirling the swirler and a slurry tank, at least one plate is provided with a vibrator made in the shape of a peripheral or central part of the plates, or the vibrator is fixed directly to the body in the place where the plates are located and is a toroidal-shaped, the stabilizer cells are square, and the ratio of the height of the stabilizer h_c to cell width b_c is in the optimum range of magnitudes: h_c/b_c=1.5–1.8; and the plates are perforated or slotted with a plate thickness ratio h_t to the width of slots b_o, located in the optimal range of values: h_t/b_o=0.8–1.5; ratio of the height of the body H to the diameter D is in the optimum range of values: H/D=4.0–6.5; ratio of the diameter of the body D to the diameter of the spray catcher D₁ is in the optimum range of magnitudes: D/D₁=1.2–1.25; ratio of the diameter of the body D to the diameters of the inlet and outlet nozzles D₂, is in the optimum range of magnitudes: D/D₂=2.0–2.5, spraying device is in the form of a vortex nozzle comprising 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, diffuser is installed in the diffuser outlet chamber, the diffuser is made in the form of at least three spokes, each of which is fixed at one end to the outer surface of the diffuser outlet chamber, perpendicular to the surface forming it, and the other to the surface of the body of rotation, for example, a ball whose axis is aligned with that of diffuser outlet chamber. Note also that said ball is located at lower part, behind the diffuser outlet chamber edge, diffuser is attached to the end surface of a cylindrical sleeve coaxial with the body, coaxial to the diffuser chamber. Cut surface of diffuser lies in a plane below the surface of the divider’s body of rotation, divider is made in the form of two spokes, each of which is fixed at one end to the outer surface of the diffuser outlet chamber, perpendicular to the surface forming it, and the other – on an axis on which a rotating body is mounted with the possibility of rotation, made in the form of a ball, the center of which lies on the axis of the diffuser outlet chamber, wherein the surface of the body of rotation, made in the form of a ball mounted on an axis with possibility of rotation, is perforated, and to the surface of the body of rotation, made in the form of a ball and mounted on the axis with the possibility of rotation, elements are installed that rotate it, for example, in the form of segments of helical blades, while on the inner surface of the central cylindrical throttle opening of the vortex nozzle of the spraying device located in the end surface of the nozzle, the screw grooves are made for additional twisting of the liquid flow, characterized in that in the rotational body of the vortex nozzle of the spraying device, whose axis coincides with the axis of the diffuser outlet chamber, and the body of rotation itself is located in the lower part behind the cutoff of the diffuser outlet chamber, resonant recesses are made in the form of a cylindrical surface of different diameters and lengths, performing the functions of Helmholtz resonators, their dimensions are determined by the necessary pulsation frequency of the liquid flow to increase the fineness of the sprayed flame.

EFFECT: increased dust collection process efficiency and reliability.
