ASH CATCHER WITH SWIRL-TYPE NOZZLES Russian patent published in 2014 - IPC B01D46/00 

FIELD: mechanical engineering.

SUBSTANCE: ash catcher with swirl-type nozzles comprises an inlet nozzle, a housing, an outlet nozzle, a batcher and fluid spray nozzles used as irrigation and spray nozzles. Nozzles of an irrigation device are designed of a swirl type, each comprises a hollow body with a nozzle and the central core, in this case the housing is designed with a channel for supplying liquid and comprises a coaxial sleeve, rigidly connected to it, with a nozzle fixed in its bottom part designed in the form of a two-step cylindrical sleeve. The upper cylindrical level is connected to the central core and a conical hub coaxial with it, in this case a socket in the form of an end circular plate with at least seven radial lobes is rigidly secured in the bottom part of a hub, and at least two series of cylindrical expansion orifices are made on the lateral surface of the hub. Moreover, at least three conical expansion orifices with an angle at a cone vertex, lying in the range from 45° to 90° is made in the end round plate. There are helical grooves on the inner surfaces of cylindrical expansion orifices made on the lateral surface of the hub.

EFFECT: improvement of efficiency of the cost-effective use of resources and cleaning of flue gases by increasing the milling loss surface due to the use of swirl-type nozzles.
