The treatment of exhaust gas should be carried out from two aspects: First, the exhaust gas dust removal for suspended granular pollutants; The second is that the control of gaseous pollutants for the purification of gaseous pollutants is mainly to separate pollutants from the exhaust gases by using the physicochemical properties, such as the differences in solubility, adsorption saturation, dew points, and chemical reactions. Or convert pollutants into harmless or easily treatable substances. The basic methods of waste gas purification include absorption method, adsorption method, condensation method, catalytic transformation method and combustion method.
An Overview of Air Pollution Control Techniques It is an important countermeasure to environmental protection of the atmosphere. Clean combustion technology is a general term for all technologies such as processing, combustion, conversion, and pollution emission control that reduce pollutant emissions and improve fuel use efficiency during the combustion process. Sulfur dioxide, nitrogen oxides and dust are the main air pollutants in China. Reducing emissions of sulphur dioxide, nitrogen oxides, and smoke(powder) dust for the protection and improvement of the atmosphere. Not only very important. And it's urgent. Therefore, the control technology of sulfur dioxide, nitrogen oxide and smoke(powder) dust is summarized below.
Clean combustion technology
Clean coal combustion technology refers to the technology that coal can reduce pollution emissions through purification before combustion and increase efficiency and reduce pollutant emissions during coal combustion. Including changing the nature of the fuel, improving the combustion method, adjusting the heating conditions, and appropriately adding additives to control the generation of pollutants.
High chimney flue gas emission technology
The high chimney discharge of flue gas is the direct discharge of pollutant flue gas into the atmosphere through the high chimney. It is the diffusion and dilution of pollutants to a larger range and beyond. Flue gas that has been purified is discharged into the atmosphere through the chimney. Using the role of the atmosphere to further reduce the concentration of surface air pollutants.
Dust treatment technology
Smoke(powder) dust purification technology, also known as dust removal technology, it is the separation of particulate pollutants from the exhaust gas and recovery of the operation process. The equipment that implements this process is called a precipitator. There are many types of gaseous pollutants and their characteristics are different. Therefore, the purification methods used are also different. Commonly used methods include absorption method, adsorption method, catalytic method, combustion method, condensation method, membrane separation method, electron beam irradiation purification method and biological purification method.
