★Product introduction of the flue gas treatment and environmental protection system for coking plants
The flue gas treatment and environmental protection system for coking plants is an environmental protection equipment system that performs phased and comprehensive purification treatment on flue gas, smoke and various harmful gases (such as SO₂, NOₓ, dust, benzopyrene, volatile organic compounds, cyanide, heavy metals, etc.) generated by coke ovens during coal distillation. The system can be applied to multiple treatment links such as coke oven exhaust gas (such as coal loading flue gas, coke pushing flue gas, and furnace top escape gas), coking waste heat boiler tail gas, and desulfurization and denitrification systems to achieve compliance or even ultra-low emissions.
Common processes include high-efficiency dust removal, dry or wet desulfurization, selective catalytic reduction (SCR) or non-catalytic reduction (SNCR) denitrification, VOCs treatment, gaseous pollutant adsorption, and waste heat recovery modules.
★Product features
Multi-pollutant coordinated treatment
It can simultaneously and efficiently remove particulate matter, sulfur dioxide, nitrogen oxides, organic pollutants and odorous gases, and has the ability to comprehensively treat flue gas in the entire process of the coking industry.
Strong adaptability to high temperature and high dust
In view of the complex characteristics of high temperature, high dust and high corrosion in coking flue gas, the system is designed with corrosion-resistant and wear-resistant materials to ensure long-term stable operation of the equipment.
High-efficiency dust removal system
Adopting electric bag dust collector or high-temperature bag dust collector, the dust removal efficiency is ≥99.9%, and the smoke concentration can be <10mg/m³, meeting the ultra-low emission standard.
Flexible desulfurization process selection
According to different flue gas components and site conditions, dry calcium spraying, semi-dry rotary atomization tower, wet limestone-gypsum method, etc. can be selected, and the desulfurization efficiency is generally ≥90%.
Controllable and stable denitrification process
Adopting SNCR or SCR process, precise spraying of ammonia or urea, denitrification efficiency is 70~90%, and NOₓ emissions are stably controlled below 50mg/m³ to ensure environmental compliance.
Strong ability to control volatile organic compounds (VOCs)
For organic waste gas generated in coal loading, coke pushing and other links, it can be equipped with regenerative thermal incinerator (RTO), catalytic combustion, activated carbon adsorption and other technologies, with a removal rate of more than 95%.
Odor and odor control
A combination system such as gas collection hood + fan conveying + scrubber + activated carbon tower can be set up to effectively control the escape of odor substances such as ammonia, hydrogen sulfide, and cyanide.
Waste heat utilization and energy saving and emission reduction
The system can be combined with coke oven waste heat boilers, waste heat power generation or heating facilities to achieve comprehensive resource utilization and operation energy consumption optimization.
Intelligent automatic control system
Adopt PLC/DCS control platform + online monitoring system (CEMS) to realize intelligent linkage of flue gas treatment equipment in each section, real-time monitoring of operation data and abnormal alarm.
Meet the latest environmental protection standards
The system design is strictly implemented in accordance with the "Ultra-low Emission Standards for Air Pollutants in the Iron and Steel Industry", "Pollutant Emission Standards for the Coking Industry", "Fixed Pollution Source Emission Monitoring Technical Specifications", etc., to meet current and future environmental protection compliance requirements.
