Desulfurization and Denitrification Agent (aqueous solution and powder)
At present, the desulfurization and denitrification of kiln flue gas generally adopts “limestone-gypsum desulfurization and NH3 selective catalytic reduction method”. However, SO2 and NOx are treated separately, resulting in issues such as large floor space, complicated equipment, high investment and operation costs, low utilization value of by-products, and secondary pollution, etc., which cannot meet the strict environmental protection requirements. Therefore, the development of an economical and efficient integrated technology for desulfurization and denitrification is a key task carried out by domestic and foreign enterprises. The integrated desulfurization and denitrification chemical additive developed by the company combines desulfurization technology and denitrification technology into a set of process, which simplifies process and equipment, and has a compact structure, less by-products, low construction cost and low operation cost.
一、Product properties
1、The technology is simple and easy to use: It uses powder conveying system to spray desulfurization and denitrification agent into appropriate position of kiln furnace to achieve the purpose of desulfurization and denitrification.
2、Small one-time investment in project construction: The technology requires small investment in equipment, which accounts for 15%~30% of investment in equipment and project construction of traditional desulfurization and denitrification technologies, such as limestone, double alkali and liquid ammonia.
3、Low operation cost: Integrated desulfurization and denitrification have lower operation cost.
4、Good effect: The technology can reduce the emission concentration of SO2 and NOx in kiln flue gas to the latest national emission standards, and even lower, which can be adjusted according to the requirements of companies.
5、No by-products, no secondary pollution: The technology decreases labor intensity, eliminates garbage clearance fees, secondary pollution treatment fees, and sewage treatment fees.
6、Energy saving function: By using the desulfurization and denitrification agent can remove the ash and coking on boiler tube wall, accelerate heat conduction and reduce the heat loss, thereby saving energy. The slight ash and coking removal have energy saving of 1~3%, and the serious one has energy saving of 4~7%.
二、Packaging and storage
1、The powder is packed in laminating plastic bags or in bulk package.
2、The aqueous solution is packed in metal bucket, of 200 kg/barrel, or stored directly in tank truck. The product shall be stored in a cold and dark place, the original seal at 0 ° C ~ 50 ° C is of 24-month warranty period, and product out of valid period can be used after being sampling and tested.
三、Safety precautions
The product is non-toxic, non-corrosive and has no pollution to the environment.
If contact skin, rinse with water; if splash in eyes, rinse with water and seek medical attention as soon as possible.
