Product Description
The third-stage dust-collection project for the converter at the Bayuquan Branch of Angang Steel Co., Ltd. is being implemented under a general contracting arrangement, covering engineering design, equipment supply, installation and commissioning, as well as technical services. Following the implementation of the third-stage dust-collection system, the particulate matter concentration in the flue gas discharged from the chimney will be ≤15 mg/Nm³. 3。
This project involves the installation of three tertiary dust-collection systems in the converter workshop of the steelmaking department, which will work in conjunction with the secondary dust-collection system to capture and purify fugitive fumes generated during the iron-adding process. Each tertiary dust-collection system is designed to handle a flue-gas flow rate of 70 × 10^4 m³/h. 3 /h. The third-stage dust-collection building for the converter is located on the vacant lot to the southeast of the existing second-stage dust-collection facility, with a rational layout that facilitates ash removal. It complies with the requirements stipulated in GB 28664-2012, “Emission Standard of Air Pollutants for the Steelmaking Industry,” thereby ensuring compliance during environmental impact assessment acceptance.
The renovation of the three-stage dust-collection system for the converter at the Bayuquan Branch of Angang Steel Co., Ltd. encompasses process facilities and associated auxiliary systems, primarily including the dust-collection network, baghouse filters, dust-collection fans, heating, ventilation and air-conditioning systems, electrical and instrumentation systems, and civil engineering works. This scope covers the design and layout of the process systems necessary for the normal operation of these systems, as well as equipment selection, procurement, transportation and storage, fabrication and installation, the design, construction, commissioning, testing and inspection of buildings and structures, trial operation, performance evaluation and acceptance, training, and final handover for operation.
Upon completion and commissioning of the project, dust concentrations at all production stations and emission concentrations from the dust collection systems will both comply with national standards.
