2、Off furnace denitrification equipment use

Off furnace denitrification equipmentIt has a wide range of uses, including Meet the requirements of environmental protection, Promote sustainable development, Flue gas denitrification, environmental protection and Improve product quality，at work,Catalysts are used to promote the selective catalytic reduction reaction between reducing agents (such as ammonia and urea) and NOx in flue gas. Under the action of catalyst, the reductant preferentially reacts with NOx to generate harmless nitrogen and water vapor, but hardly reacts with oxygen in flue gas. This chemical reaction is usually carried out in the temperature range of 200-450℃, and the specific reaction temperature depends on the type of catalyst selected.。

3、Off furnace denitrification equipment structure

The Off furnace denitrification equipment structure is introduced as follows:

1. Reducing agent supply

Reducing agents such as liquid pure ammonia or ammonia water (aqueous solution of ammonia) are evaporated and mixed with diluted air or flue gas.

2. Catalytic reduction reaction

Under the action of catalyst, the reductant and NOx in flue gas undergo selective catalytic reduction reaction to generate nitrogen and water vapor.

3. Flue gas mixing and distribution system

Ensure that the flue gas and reducing agent are fully mixed in the reactor to improve the denitrification efficiency.

4. Reducing agent supply

Reducing agents such as liquid pure ammonia or ammonia water (aqueous solution of ammonia) are evaporated and mixed with diluted air or flue gas.

5. Reducing agent storage and supply system

Used to store and supply reducing agent (such as ammonia or urea solution) to the reactor.

4、Off furnace denitrification equipment advantage

The advantages of Off furnace denitrification equipment are as follows:

1. High efficiency denitration capacity

Gate is famous for its high efficiency of denitration, which can usually reach more than 90% denitration efficiency. This means that the Off furnace denitrification equipment technology can significantly reduce the concentration of nitrogen oxides (NOx) in flue gas and make it meet strict environmental protection emission standards. This high-efficiency denitration ability mainly benefits from the promotion of catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.

2. Diversity and high efficiency of catalysts

There are many kinds of catalysts used in the Off furnace denitrification equipment technology, including vanadium-based catalysts and titanium-based catalysts, which can promote the chemical reaction between reductant and NOx at low temperature. At the same time, the active components and carrier materials of the catalyst are constantly being developed and improved to improve its catalytic efficiency and service life. This enables the Off furnace denitrification equipment technology to maintain high efficiency of denitration in a wider temperature range and more complex flue gas conditions.

3. Intelligent control and convenience of operation

The Off furnace denitrification equipment has gradually realized intelligent control. By integrating advanced control system and sensor technology, the Off furnace denitrification equipment can monitor the composition and emission concentration of flue gas in real time, and automatically adjust the injection amount of reductant and the active state of catalyst to ensure the stability and reliability of denitrification efficiency.

4. economic viability

The initial investment of this technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of Off furnace denitrification equipment technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, Off furnace denitrification equipment technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.

5. Environmental friendliness

The by-products produced by Off furnace denitrification equipment technology are mainly nitrogen and water vapor, which are harmless to the environment and will not cause secondary pollution. Compared with the traditional wet flue gas denitrification technology, the Off furnace denitrification equipment technology does not need to use a lot of water resources and will not produce pollutants such as wastewater, which is more in line with the requirements of environmental protection and sustainable development.
