In terms of air pollution prevention and control, the main pollutants in industrial kilns are dust particles, SO2, and NOx.

Hubei Glass Technology Co., Ltd.'s photovoltaic rolled glass high-temperature composite filter cartridge dust, nitrate, and sulfur integration project uses more than 5000 high-temperature composite filter cartridges. This process achieves simultaneous desulfurization, denitrification, and dust removal of high-temperature flue gas. Removing the heat exchange process in traditional techniques while reducing project investment. The project was completed and put into operation on May 10, 2024. After testing, the flue gas emissions were found to be<20mg for sulfides,<30mg for nitrogen oxides, and<5mg for particulate matter, which are far below the design and environmental impact assessment requirements (sulfides<35mg, nitrogen oxides<50mg, and particulate matter<10mg), meeting the ultra-low emission standards.

The high-temperature composite filter cartridge dust, nitrate, and sulfur integrated equipment is the best choice for flue gas treatment. It has advantages such as more efficient desulfurization, denitrification, dust removal, and stable performance compared to conventional bag products. It is suitable for industries such as hazardous waste boilers, waste heat power generation, coking industry, glass industry, cement industry, metallurgical industry, steel industry, sludge incineration, garbage incinerators, small coal-fired boilers, lime kilns, etc., where the composition of flue gas emissions is complex, ash viscosity is high, and conventional processes are difficult to achieve ultra-low emissions. This technology can also play a role in high-temperature flue gas waste heat utilization, completely solving the problem of flue gas reuse in blast furnaces or alloy furnaces, achieving effective energy saving and consumption reduction. It has profound significance for the increasingly high environmental and energy-saving requirements in China.

Advantages of the high-temperature composite filter cartridge dust, nitrate, and sulfur integrated system: It has the characteristics of corrosion resistance, high temperature resistance, high efficiency, integrated catalysis, and integrated molding, and can efficiently remove dust particles, sulfides, and nitrogen oxides from industrial flue gas. The by-products generated during the processing are minimal, which reduces the operating costs compared to traditional processing techniques and allows for long-term stable operation.

The traditional high-temperature flue gas treatment process is mainly composed of separate equipment and independent systems. Its disadvantages include a large system, decentralized control, and multiple fault points; Split equipment occupies a large area and is difficult to arrange; Pre dust removal equipment and SCR denitrification system must be newly added equipment; Poor smoke circulation, high system resistance, high energy consumption, and high project investment.
