T/JCZX 001-2020 Technical Standards for the Upgrading and Transformation of Foundry Pig Iron Enterprises in Jincheng City

Scope

Main technical content: 1. Plant layout and environment; 2. Raw material transportation and storage; 3. Sintering (pelletizing); 3.4 Environmental protection facilities for the sintering (pelletizing) process; 3.4.1 For the sintering machine head fumes, it is recommended to use a four-field horizontal electrostatic precipitator + wet desulfurization (dry/semi-dry) + SCR denitration + wet electrostatic precipitator (high efficiency bag filter or cartridge filter). Desulfurization can use wet desulfurization processes such as limestone/lime-gypsum, and semi-dry desulfurization processes like circulating fluidized bed, rotary spray, and dense-phase dry tower. The wet desulfurization facilities need to be equipped with a wet electrostatic precipitator; denitration can use selective catalytic reduction (SCR) technology. 3.4.2 For the sintered ore screening waste gas (containing highly abrasive dust in the waste gas), it is recommended to use ultra-fine fiber surface needle-punched/water-jet filter media, and not to use coated filter media. 3.4.3 For dust-prone operations such as crushing and screening, it is recommended to completely or partially enclose the production equipment and seal them with rubber curtains. 3.4.4 The sintering machine cooling machine should be completely enclosed. 4. Automation and monitoring systems; 5. General technical requirements for environmental protection facilities; 6. Energy consumption indicators and energy-saving measures for production processes
