DEVICE FOR THERMAL NEUTRALISATION OF LIQUID WASTES Russian patent published in 2012 - IPC F23G7/04 F23N5/00 

FIELD: power industry.

SUBSTANCE: in device for thermal neutralisation of liquid wastes, which involves horizontal flame burners, for example two of them, gas header, gas inlet branch pipe, with flame arrester arranged at the edge, liquid waste header, liquid waste inlet branch pipe, at that, gas and liquid waste headers are connected to flame burners, the device is equipped with a spreader in the form of Coanda body, which is arranged on the header, parallel to horizontal flame burners there installed is pilot burner, and in the housings made in the form of tubes there arranged is ignition burner and flame scanner. Recirculation station made of two coaxial tubes is installed opposite the outlet of gas-liquid mixture from flame burners; besides, inner tube is shorter than outer one; convergent branch pipe is arranged at the recirculation station inlet and divergent branch pipe is installed at recirculation station outlet so that annular space is formed between edges of inner tube and internal surfaces of convergent branch pipe and divergent branch pipe, as well as between inner tube and outer tube.

EFFECT: higher liquid waste neutralisation quality.
