CONICAL JET SCRUBBER Russian patent published in 2018 - IPC B01D47/14 B01D53/18 B05B1/34 

FIELD: dust collection equipment.

SUBSTANCE: invention relates to wet dust collecting equipment. Conical nozzle scrubber comprising a housing with nozzles for dusty and clean gas, a nozzle spraying device, supporting and restrictive trays, 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 having a section perpendicular to the screw line, a profile such as a circle, a polygon, a Berl saddle or an itallox saddle, the spraying device is in the form of vortex nozzles, each of which consists of 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, 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 by the other end – in the surface of the body of rotation, for example, a ball whose axis coincides with the axis of the outlet diffuser chamber, and the body of rotation itself is located in the lower part behind the cutoff of the diffuser outlet chamber, a diffuser is attached to the end surface of a cylindrical sleeve, coaxial with the housing, coaxial to the diffuser chamber, which slice surface lies in plane located below splitter body of rotation surface, 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 rotational body is arranged with possibility of rotation in the form of a ball centered on the axis of the diffuser outlet chamber, wherein the surface of the rotational body 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, 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 body of rotation of the vortex nozzle, 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 efficiency and reliability of the dust collection process by increasing the liquid spraying rate of injectors.
