The film tells about the technological processes of gas purification in steelmaking using wet and dry methods.
Steelmaking.
A series of shots taken at enterprises in industries that use metals intensively.
Technological dust and gas emissions during metal production.
Significant volumes of dusty gases are emitted from electric furnaces during the period of metal boiling and oxygen purging of the bath.
Chemical composition of gases emitted from electric steelmaking furnaces.
Pipes of a steelmaking shop.
A cartoon about the harmful effects of gas on the environment.
USSR Law on the Protection of Atmospheric Air.
Wet gas cleaning system in steelmaking.
A cartoon explaining the wet cleaning system.
Removing sludge from an inertial collector.
Continuation of the cartoon.
Smoke exhausters, with the help of which gases are sucked out of electric furnaces.
A smoke exhauster is a fan.
Smoke exhauster design.
A cartoon explaining the operation of a smoke exhauster.
Sludge is pumped to the sludge processing shop by powerful pumps.
Screw feeders feed the pulp to the disk vacuum filters.
Dehydrated and specially prepared sludge is used in production.
Clarified water is returned for cleaning.
Scheme of the reverse cycle of water supply of the wet gas cleaning system.
Dry method of gas cleaning in fabric bag filters.
The heated gas discharged from the furnace first enters the afterburning chamber.
Before being fed to the bag filters, the gas passes through a system of pipelines, where it is cooled by the suction of atmospheric air.

Control panel for gas cleaning.
Monitoring devices.
Operating temperature of gases during cleaning in cotton and lavsan sleeves, as well as during cleaning in synthetic and fiberglass pipes.
Cartoon explaining the operating principle of fabric filters.
The process of removing dust from sleeves.
Shaking and reverse blowing mechanism.
Dust collection bin.
Cleaned gas is discharged into the atmosphere through a chimney.
The operation of the sleeve filter is controlled from a control panel equipped with measuring devices, automatic control devices, as well as sound and light alarms.
Cartoon explaining the use of electrostatic precipitators in dry cleaning.
Periodically, the electrodes are shaken using special devices.
Dust accumulates in the bin, from which it is unloaded using screw feeders.
Gases from electric furnaces are emitted not only during the smelting process, but also when tapping finished steel into the ladle, as well as during the furnace loading period.
Exhaust shafts in the roof of the workshop that capture fugitive emissions and send them for purification.
Cartoon explaining the capture of fugitive emissions.
View of pipelines removing fugitive emissions.
