Introduction to Iron Water Dust Removal Desulfurization
Iron water spray dedusting desulfurization technology is a common desulfurization method which uses the water droplets produced by the atomization of high-pressure water to attach dust to the water droplets and combine them with the adsorption of absorbent. After desulfurization, it is discharged through the dust collecting device. The iron-water spray dedusting desulfurization device can make full use of the water droplet inertia generated by high-pressure atomization, make the dust particles suspended in the air collide with the water droplets, and separate the dust from the flue gas.
Process Flow
Iron water dust removal desulfurization is mainly composed of absorption tower and dust collector. The general working process is as follows: firstly, the desulfurized exhaust gas enters the absorption tower, and then the cleaning agent is uniformly arranged in the absorption tower. The cleaning agent can mix with the exhaust gas and further chemically react with hydrogen sulfide and other acidic gases in the exhaust gas, so as to achieve the purpose of sulfur removal. Then spray the high-pressure water into the absorption tower, and atomize it into a very fine mist aerosol. The dust particles suspended in the exhaust gas in the absorption tower collide with the aerosol and attach the dust to the surface of the water droplets. The finer the water droplet and the longer the residence time of the aerosol, the better the dust removal effect. Finally, after the dust attached to the surface of the water droplet droplets out of the absorption tower, through the dust collector, using the gravity settling and other methods of dust removal effect, so that the exhaust gas can achieve the purpose of emission reduction.
Features
The features of iron water spray dedusting desulfurization technology are mainly reflected in the following aspects:
1. The volume of the equipment is small, which occupies a small area and is suitable for occasions with limited space;
2. The efficiency of dust removal is large and the effect of reducing particulate emissions is good.
3. The technological process is simple and the operating cost is low;
4. Using automatic control system, it can realize automatic cleaning and automatic control, reduce labor intensity and improve operating efficiency.
5. Compared with the electrostatic dedusting absorption desulfurization device, the amount of water used is small, and the equipment is not prone to fouling;
6. The structural parameters can be adjusted, and it is flexible and convenient and easy to scale up and down.
Conclusion
Iron-water spray dedusting desulfurization technology is an advanced technology for sulfur removal and dust control. Its advantages of small area and high dust removal efficiency make it widely used in industrial boilers and waste gas treatment systems. It is of great significance to reduce air pollution and improve air quality.
