With over 20 years of experience in the environmental protection industry, Taiji Environmental Protection has remained focused on air pollution control. Leveraging our end-to-end service capabilities, we provide clients with one-stop, in-depth solutions for air pollution control.
Flue Gas Desulfurization
The DS Multiphase Reactor, Taiji Environmental Protection's core desulfurization equipment, is suitable for flue gas treatment in hazardous waste, iron and steel, nonferrous metals, chemicals, building materials and other industries, and meets ultra-low emission requirements. It received the 20th China Patent Excellence Award and was listed in the Guidance Catalogue for the Promotion and Application of the First (Set) Major Technical Equipment (2019 Edition) issued by the Ministry of Industry and Information Technology (MIIT).

SCR Denitrification
Selective Catalytic Reduction (SCR) denitrification uses a catalyst to selectively react a reducing agent—typically ammonia (NH₃)—with nitrogen oxides (NOx) in flue gas, converting NOx into nitrogen (N₂) and water (H2O). Drawing on years of proven experience, Taiji Environmental Protection has developed an integrated SCR technology system. It is widely adopted across industries such as iron and steel, nonferrous metals, coking, thermal power, and hazardous waste treatment. The SCR unit can be configured either downstream or upstream of the flue gas desulfurization (FGD) system, depending on flue gas conditions.

Baghouse Dust Collection
Baghouse dust collection is a technology that uses filter media (filter bags) to separate and capture dust particles from flue gas. It is widely used in cement, power, metallurgy and other industries. At its core is the bag filtration system. The equipment has a simple structure, and its selection must take into account flue gas temperature, dust concentration and other factors.

Advanced Particulate Matter Purification
Taiji Environmental Protection's self-developed wet electrostatic precipitator (WESP) provides advanced equipment for haze control and ultra-clean flue gas emission in industries including iron and steel, nonferrous metals, coking and hazardous waste treatment. Typically installed after the wet desulfurization unit, it efficiently collects gypsum droplets, acid mist, aerosols and other pollutants, achieving ultra-low flue gas emission across a wide range of applications.

White Plume Abatement
Taiji Environmental Protection combines air-cooling technology with existing wet flue gas desulfurization systems to specifically address the "white plume" issue at the stack outlet after wet desulfurization. It fundamentally eliminates visual pollution and secondary impacts such as rainout around the stack, helping enterprises achieve both cleaner emissions and an improved visual profile. The technology is widely applicable to retrofitting and upgrading existing wet desulfurization systems as well as to new projects.

Multi-Pollutant Synergistic Control (CO, VOCs, NOx)
The DS Combustion Purification Heat Recovery System is a technology and equipment for the synergistic control of multiple pollutants (CO, VOCs and NOx) in industrial furnace and kiln flue gas, independently developed by Taiji Environmental Protection. It is mainly applicable to the removal of multiple pollutants (CO, VOCs, NOx, dioxins and other pollutants) generated by industrial furnaces and kilns in metallurgy, chemicals, building materials and hazardous waste incineration. The system comprises four modules: an indirect heat exchange module, Regenerative Heat Recovery Module, a combustion purification module and an SCR denitrification module. As a high-efficiency, energy-saving solution for multi-pollutant synergistic control, it effectively tackles the problem of high additional energy consumption in SCR denitrification.
