Summary:

The design of the gas-cleaning equipment complex is considered, which makes it possible to produce an active non-uniformselective effect on the environment being processed – blast furnace gas from converters and converters, under the conditions of the blast furnace and steelmaking redistribution, to reduce energy consumption (electricity, water) in the process of cleaning emissions and capital costs. The main components of the designed structure of this complex are presented in the form of energy-intensive adjustable tandem wet gas cleaning installations (ERTUMG), formed by identical structural nodes and elements, the gas exhaust paths of which are connected by a collector duct equipped with an automatically controlled shutoff valve. In the collectors of the circulating water supply to the wet gas cleaning apparatus, at the entrances to the scrubber and the Venturi tube unit (ERTUMG), water flow sensors and automated adjustable throttle valves are installed, the drive control of which is connected to the control panel of the metallurgical unit, which provides a direct, direct dependence of the parameters of the gas cleaning operation with the phase of the technological cycle in which the metallurgical unit is located. In the flue gas ducts of the gas exhaust ducts (ERTUMG), flow sensors of the cleaned gas and automatically controlled shutoff valves are installed, the drive control of which is also connected to the control panel of the metallurgical unit, to ensure a direct dependence of the parameters of the gas cleaning operation on the phase of the technological cycle metallurgical unit. The developed complex of gas-cleaning equipment is intended for operation in the conditions of oxygen-converting shops of metallurgical enterprises and takes into account the specifics and modes of operation of the existing process equipment: capacity, performance and technological modes of operation of installed converters.
