HYDRAULIC ASH CATCHER - HEAT RECOVERY UNIT Russian patent published in 2014 - IPC B01D47/06 

FIELD: machine building.

SUBSTANCE: hydraulic ash catcher - heat recovery unit comprises an inlet pipe branch, a casing, an outlet pipe branch, a settling chamber being filled with water up to the level of a partition wall immersed in the chamber, the lower part of the partition wall is fitted by longitudinal grooves with permanent pitch, an inlet gas duct is equipped by a water sprinkler made as a manifold with nozzles, a pipeline, a screw pump, a tank to collect water, an overflow opening with regulated gate valve, a discharge pipe branch, a tubular coil, each of the nozzles comprises a case fixed on the manifold and a throttle opening with a chamber, and the case is made from two parts coaxial to each other: the base and the cover which are rigidly attached to each other by means of four latches, and an inlet pipe branch creating vortex head pressure in the nozzle case is tangentially attached to the base. The cover plate is volume-type as to evolvent profile with a central conical hole, with a cone apex angle equal to 130°, and the base is shaped, and has a central fairing of vortex flow, which is formed by the conical surface transforming into a sphere at the apex directed towards the central conical hole in the cover, and the base of the conical surface is smoothly adjacent to the toroidal surface of the base.

EFFECT: higher operation reliability.
