LIQUID WASTES THERMAL NEUTRALIZING PLANT Russian patent published in 2008 - IPC F23G7/04 

FIELD: different industries.

SUBSTANCE: invention relates to thermal neutralization of liquid wastes by fire method. Proposed plant contains tank for treatment of liquid wastes with emergency drain branch pipes, vapor-gas mixture outlet branch pipe and branch pipe to direct concentrate to device separating liquid waste suspension into liquid and hard phases, pulsating burning chamber with burners, resonance pipe, and cyclone bubble evaporator. Plant is furnished with ejector connected, accordingly, by pipelines with liquid waste feed pump, ozone-air mixture feed source and liquid waste and ozone-air mixture heater arranged in resonance pipe connected by pipeline with self-contained energy complex hydraulic steam turbine-generator connected by pipelines, respectively, with preliminarily treated liquid waste tank and with suction pipeline of air blower providing delivery of vapor-air mixture with liquid waste treatment products into pulsating burning chamber, and liquid waste, into tank for preliminarily treated liquid waste connected by pipeline with liquid products treatment tank. In lower part of the latter, sensors are arranged to measure electric conductivity of concentrate and check content of harmful organic admixtures being connected by electric circuits, respectively, with device for automatic control and shut off-and-control valve arranged on branch pipe directing concentrate to separator of suspensions into liquid and heard phases providing automatic removal of said phases.

EFFECT: reduced specific consumption of fuel in process of neutralization and discharge of carbon dioxide and nitrogen oxides into atmosphere.
