Blast Furnace Gas Metal Membrane Ultra-Fine Dust Removal and Emission
The company's metallurgical special valves are mainly used in energy-saving and emission reduction systems such as blast furnace gas dry dust removal and gas recovery in the metallurgical industry, with a domestic market share of more than 70%. Energy and petrochemical valves with harsh working conditions and low leakage requirements are the main domestic suppliers of nuclear-grade butterfly valves and ball valves.

Introduction
The primary dust removal system for the steelmaking converter uses a dry process, and the electrostatic precipitator is the key dust removal equipment in the dry dust removal system for converter flue gas. Due to the high dust content in converter gas, the dust concentration at the outlet of the electrostatic precipitator is generally 15-30 mg/Nm.3This does not meet the ultra-clean emission requirement of <10 mg/Nm.3To address this, a new metal membrane fine dust collector has been added between the vent cup valve and the vent chimney to purify the flue gas from the primary dust removal of the converter, meeting environmental protection requirements.
The primary metal membrane dust removal for converter flue gas replaces the electrostatic precipitator, achieving ultra-clean dust removal directly. It has a high safety factor, reduces production losses caused by maintenance and inspection of the electrostatic precipitator, and decreases wear on the induced draft fan, significantly reducing ash accumulation in the converter gas pipeline and gas cabinet.
The ultra-clean emission from the primary dust removal of the converter has been implemented at Jinxigang Steel's 2×150t/h converter, operating stably since May 11, 2021; the metal membrane replacing the electrostatic precipitator for ultra-clean dust removal system has been implemented at Jinxigang Steel's 120t/h converter, operating stably since May 3, 2023. According to third-party testing, the dust concentration at the outlet of both systems is less than <5 mg/Nm.3。
The company's "butterfly ball" brand is a well-known trademark in China, the "magic" brand has completed the Madrid international trademark registration, and the "STV" brand has completed the Chinese trademark registration. The company has passed the API certification of American Petroleum Institute, BV certification of French Classification Society, ISO9001 quality management system, ISO10012 measurement management system, ISO14001 environmental management system, GB/T45001-2020 occupational health and safety management system, GB/T29490 intellectual property management system certification and CNAS laboratory accreditation.
