SCRUBBER Russian patent published in 2018 - IPC B01D47/06 B01D53/18 B05B1/34 

FIELD: dust collection equipment.

SUBSTANCE: invention relates to wet dust collecting equipment. Scrubber comprising a body including a conical, cylindrical portion and a slurry tank, a nozzle for introducing a dusty gas, a branch pipe for the outlet of a cleaned, spraying device including an external pipeline with embedded lower and upper nozzles, the ratio of the diameter of the apparatus D to the diameter of the inlet branch pipe D_o is in the optimal range of values: D/D_o=2.2…2.5, and the ratio of the height of the apparatus H to the diameter of the inlet branch pipe D_o is in the optimum range of magnitudes: H/D_o=4.8…5.7, and the nozzles are in the form of vortex nozzles, each of which comprises a body 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, at that coaxially with the body, a nozzle, in the form of an inverted cup, is connected to the sleeve by means of a thread, in the bottom of which there is a turbulent swirler of the liquid flow with at least two inclusions to the nozzle axis in the form of cylindrical holes 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, the surface of the body of rotation made in the form of a ball mounted on the axis with the possibility of rotation is perforated, to the surface of the body of rotation, made in the form of a ball mounted on an axis with the possibility of rotation, elements that rotate it are installed, for example in the form of segments of screw blades, screw grooves are provided on the inner surface of the central cylindrical throttle opening of the vortex nozzle disposed in the end surface of the nozzle for additional twisting of the liquid flow., characterized in that in the rotational body of the vortex nozzle, axis of which coincides with the axis of the diffuser outlet chamber, and the body of rotation itself is located at the bottom, behind the cut of the diffuser outlet chamber, resonant recesses are made in shape in the form of a cylindrical surface of different diameters and length, 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 efficiency and reliability of the dust collection process by increasing the liquid spraying rate of injectors.
