SYSTEM FOR AUTOMATIC CONTROL AND REGULATION OF INDUSTRIAL AND ENVIRONMENTAL SAFETY OF EMISSIONS OF HARMFUL VAPOURS AND GASES OF ACIDIC AND ALKALINE NATURE AFTER SAFETY VALVES IN EMERGENCY SITUATION Russian patent published in 2013 - IPC G01N7/00 

FIELD: chemistry.

SUBSTANCE: system for automatic control and regulation of industrial and environmental safety of emissions of harmful vapours and gases of acidic and alkaline nature after safety valves in an emergency situation has a device for collecting and condensing the gas-vapour phase, which has a vapour ejector and a container with a central perforated tube. The system further includes: a unit for monitoring emergency situations, having a chromatograph and a device for automatic sampling of gas from a receiving tube, a valve for feeding water vapour into the vapour ejector, for intake of harmful vapours and gases from the receiving tube into a device for neutralising harmful vapours and gases. The device for neutralising harmful vapours and gases is in form of a container with nominal diameter (Du) 400 mm with a central perforated tube with Du 250 mm with openings F 2-3 mm. The container has an elliptical bottom and three nozzles: an upper nozzle for an air vent with a flame arrester at the end; a middle nozzle for periodically feeding aqueous solution of the neutralising substance into the device for neutralising harmful vapours and gases; a lower nozzle for releasing the reacted neutralisation product through a control valve into the intermediate vessel of a water-contaminant separator, where there is a level metre, from which said mixture is periodically pumped for recycling by a pump.

EFFECT: reduced environmental pollution by emissions of harmful gases and vapours of acidic or alkaline nature after safety valves in emergency situations through neutralisation thereof.
