A Computer Aided Design Method for Parameters of Converter Primary Dust Removal og System

Abstract

The invention discloses a computer-aided design method for parameters of an OG system for primary dust removal of a converter, and belongs to the technical field of OG system parameter design. The present invention first determines the design parameters of the high-efficiency washing tower and the annular venturi tube, the operating parameters of the OG system, and the thermal physical parameters of the flue gas; respectively establishes the mathematical models for the design and calculation of the parameters of the high-efficiency washing tower and the annular venturi tube according to the determined parameters; According to the determined parameters, the geometric parameters and operating parameters of the high-efficiency scrubber and the annular venturi tube are respectively obtained; and AutoCAD is connected to AutoCAD through VB, and AutoCAD automatically reads the above-mentioned geometric variables and establishes corresponding graphic variables according to their geometric values, and draws the high-efficiency scrubber AutoCAD drawings with circular seam venturi and export. According to different working conditions, parameter input, parameter design calculation, parameterized drawing and optimization and adjustment of high-efficiency scrubber and annular venturi can be carried out to obtain higher design efficiency and 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...
