Converter primary dedusting OG system parameter computer aided design method

Abstract

The invention discloses a converter primary dedusting OG system parameter computer aided design method, and belongs to the technical field of OG system parameter design. The method comprises the stepsthat firstly, efficient scrubbing tower and circular seam venturi tube design parameters, an OG system operating parameter and a gas thermal property parameter are determined; mathematical models forparameter design computing of an efficient scrubbing tower and circular seam venturi tube are respectively established according to determined parameters; the determined parameters are called to respectively obtain geometrical parameters and operating parameters of the efficient scrubbing tower and circular seam venturi tube; AutoCAD is connected through VB, the AutoCAD automatically reads the geometrical variables, establishes corresponding graphic variables according to geometrical values of the geometrical variables, and paints and exports AutoCAD drawings of the efficient scrubbing towerand circular seam venturi tube. The converter primary dedusting OG system parameter computer aided design method has the advantage that the parameter input, parameter design computing, parametric drawing, optimization and adjustment of the efficient scrubbing tower and circular seam venturi tube can be performed for different working conditions to obtain higher design efficiency and an optimal parameter design.

Description

technical field [0001] The invention relates to the technical field of parameter design of an OG system for primary dedusting of a converter, and more specifically relates to a method for computer-aided design of parameters of an OG system for primary dedusting of a converter. Background technique [0002] The iron and steel industry is one of the pillar industries of the national economy, and it is also a key industry for energy consumption and pollution discharge. OG (Oxygen Converter Gas Recovery) system for primary dedusting of converter has the characteristics of low energy consumption and high purification efficiency, and has broad market prospects. [0003] During the oxygen-blowing smelting period, the converter produces high-temperature flue gas containing a large amount of carbon monoxide and iron-containing dust. How to rationally use the chemical energy and apparent energy in the waste gas and iron-containing dust to ensure the quantity and quality of flue gas re...
