Application of Constant Pressure Variable Frequency Speed Regulation Model in Dust Removal for Casthous in Meigang
PENG Zhiping
Abstract：According to different conditions of blast furnace casthouse, the article designs a frequency control model of speed regulation which can keep dedust pressure constant for blast furnace casthouse dust, can meet the needs of normal flue gas volume in the process of blast furnace production, can keep the pressure constant of gas piping stress. By means of the field dedusting valve control technology, due to it is set in the dust control mud gun in front of the furnace operation room, it can finish the operation of the dedusting valve and fan. The application in Meigang’s No.5 blast furnace fan installed with 2×2 (4 070 m3, 240 kW) shows that the field of iron dust removal fan ton iron total power consumption is 5.78 kW·h, energy conservation and emissions reduction effect is obviously.
