VENTURI SCRUBBER WITH FINELY DIVIDED IRRIGATION Russian patent published in 2017 - IPC B01D47/00 B05B1/26 A62C31/02 

FIELD: machine engineering.

SUBSTANCE: venturi scrubber with finely divided irrigation, includes a confuser, a neck, a diffuser, an irrigation system, a drop catcher, and in the confusor the reflux device is installed, it comprises water pipelines, made in form two mutually perpendicular sections, one section is installed axisymmetric to the confusor, and at its end looking towards manhole the reflux system atomizer is installed. Irrigation system jet contains hollow casing with nozzle and central core, the casing is made with channel for liquid supply and contains coaxial rigidly connected with it sleeve with nozzle secured in its bottom part, nozzle is made in form of cylindrical two-step sleeve, top cylindrical step is connected by means of the thread joint with the coaxial with it central core having central hole and installed with ring clearance relatively to the internal surface of the cylindrical sleeve. The mentioned annular gap is communicated with at least three radial channels made in the mentioned two-step sleeve to communicate it with annular cavity formed by sleeve inner surface and top cylindrical step outer surface, the annular cavity being connected to the channel of the housing for liquid supply. The diffuser is rigidly attached to the central core, at its lower part, and is made in the form of a truncated cone coaxial to the central hole of the core and attached by its upper base to the base of the cylinder of the central core, and a divider is attached to the lower base of the truncated cone by means of at least three spokes, the diffuser is made in the form of an end circular plate the edges of which are bent toward the annular gap, and on the outer side surface of the truncated cone there are screw grooves. The throttling opening is arranged in the divider axisymmetrically to the central hole of the central core. The external diffuser is coaxially attached to the hub rigidly connected to the housing in its lower part, and the lower base of the truncated cone of a nebulizer rigidly attached to the central core in its lower part. On the outer side surface of the truncated cone there are screw grooves, the internal perforated diffuser is coaxially attached in such a way that the output sections of the external and internal diffusers lie in one plane.

EFFECT: improved efficiency of gas purification from dust and chemical impurities.
