★Calcining Furnace Flue Gas Treatment and Environmental Protection System Product Introduction
The calcining furnace flue gas treatment and environmental protection system is a special treatment system for flue gas generated by calcining furnaces (such as rotary kilns, vertical kilns, boiling furnaces, etc.) in industries such as cement, lime, non-ferrous metals, ceramics, and lithium battery materials. The system is mainly used to remove pollutants such as dust, sulfur dioxide (SO₂), nitrogen oxides (NOₓ), fluorides, and heavy metals in the flue gas to achieve standard or ultra-low emissions.
The system integrates a number of core technologies such as high-temperature dust removal, desulfurization and denitrification, heavy metal capture, and secondary heat recovery to meet the needs of environmental protection emissions and energy recovery under different working conditions.
★Product Features
High-temperature and high-dust flue gas has strong adaptability
The system is specially designed to treat calcining process flue gas with high temperature and high dust concentration. The equipment is made of high-temperature resistant and corrosion-resistant materials with high operating reliability.
Integrated treatment of multiple pollutants
The combined process of "low nitrogen combustion + SNCR/SCR denitrification + dry/semi-dry/wet desulfurization + high-efficiency dust removal" is adopted to simultaneously and efficiently remove NOₓ, SO₂ and particulate matter with high treatment efficiency.
High-efficiency dust removal
Equipped with bag dust collector or electric bag composite dust collector, the dust removal efficiency is more than 99.9%, and the particulate matter emission can be controlled within 10mg/m³ or even lower.
Flexible and diverse desulfurization processes
According to the flue gas composition and emission standards, limestone-gypsum method, dry method (spray drying), semi-dry method or sodium-based absorption and other processes are selected to meet different emission requirements.
Precise control of nitrogen oxides
Through low nitrogen combustion technology combined with selective non-catalytic reduction (SNCR) or catalytic reduction (SCR) technology, the NOₓ removal rate can reach more than 70~90%.
Control of heavy metals and harmful components
Activated carbon injection, dry adsorption tower and other devices can be added to adsorb and remove harmful components such as mercury, lead, dioxins in flue gas.
Waste heat recovery saves energy and reduces consumption
The system can integrate flue gas waste heat recovery module, use flue gas heat energy for power generation, heating or process reuse, and improve overall energy utilization efficiency.
Intelligent control system
The system integrates DCS or PLC automation control platform, supports remote monitoring, real-time feedback of operation status, abnormal alarm, and improves system intelligence and operation safety.
Emission compliance and environmental protection compliance
Meet the latest national and local standards for industrial kiln emissions (such as "Cement Industry Air Pollutant Emission Standards" and "Industrial Furnace Air Pollutant Emission Standards", etc.).

★FAQ

Q. How high is the dust removal efficiency of bag filters?
A. The dust removal efficiency can generally reach more than 99%, and can effectively filter fine dust above 0.3 microns.

Q. Can bag filter handle high temperature gas?
A. It can handle high temperature gas up to about 250℃. It needs to use high temperature resistant filter material and control the temperature and humidity of the gas.

Q. How to extend the service life of bag filter?
A. Choose appropriate filter material, clean dust on time, avoid high temperature shock and dust blockage, and perform regular inspection and maintenance.
