Abstract

Abstract: Mechanical vacuum pump system has gradually replaced the steam vacuum pump system in the field of steel refining, and a reasonable and efficient dust removal system is a necessary measure to ensure the normal operation of the mechanical vacuum pump system. This paper introduces the design and working principle of mechanical vacuum pump dust removal system, and analyzes the common problems and causes of dust removal system. Combined with the relevant engineering practical experience, the dust removal system is optimized and improved, including two-stage gas cooling system, automatic pulse purge system, automatic dust transferring system, and waste gas monitoring and alarm system. The optimized and improved dust removal system has been continuously operated in the RH vacuum refining furnace project of a new electric furnace steel-making plant for more than one year, effectively protecting the operation of mechanical vacuum pump and meeting the production process requirements for RH vacuum refining furnace.

Key words: mechanical vacuum pump, dust removal system, vacuum refining, gas cooler, bag dust removal filter
