SGⅡ wet desulfurization and dust removal technology
The SGⅡ wet desulfurization and dust removal technology is a key desulfurization technology in Chinas intelligent environmental protection. The entire process of this technology is: firstly, the high temperature flue gas generated by combustion is cooled and cooled with water, and its temperature is reduced to 140 ° C or less; then, a sulfur-containing aerosol suspended in the flue gas is extracted and absorbed by a finely atomized water mist using a spray tower. When the flue gas passes through the separator, most of the fine dust is trapped and the atomized water is used for the dust absorption and desulfurization effect; and then, the desulfurized flue gas is further cooled in the cooling tower, and the acidic mist is separated from the flue gas, and is injected into the absorber. The final pollutant, sulfur dioxide and dust, are captured and removed from the flue gas, producing clean flue gas that meets the national emission standards. The core components of the SGⅡ wet desulfurization and dust removal system include: an absorber, a separator, a spray tower and a cooling tower.
The SGⅡ wet desulfurization and dust removal system has the following advantages:
1. Low investment cost. Compared with the other physical dust removal and desulfurization technologies, SGⅡ wet desulfurization and dust removal technology has the advantages of low cost, small volume and simple process.
2. High dust removal and desulfurization efficiency. The SGⅡ wet desulfurization and dust removal system has a flue gas moisture content of over 80%, which is beneficial to capture the fine particles and aerosols and achieve the dust removal and desulfurization effect.
3. High-efficiency utilization of resources. The sulfur dioxide is not directly discharged into the atmosphere, but captured in the form of slurry, and then recycled, which not only reduces pollution, but also realizes complete energy and resource utilization.
4. High reliability. The entire process of the SGⅡ wet desulfurization and dust removal system is controlled by a computer, which has the advantages of high reliability and high maintenance rate.
The SGⅡ wet desulfurization and dust removal system has a high removal efficiency of dust and sulfur dioxide and other pollutants. Its continuously improved accuracy in terms of controlling technology and process optimization has greatly promoted the level of China’s intelligent environmental protection technology.
