In many industrial processes, air serves as the working medium and is thereby altered in composition or impurities increase to such during pneumatic conveying bulk materials.
Many specks of dust are harmful, toxic or explosive and damage people and the environment. If the air can be conducted later from the process back in the atmosphere, the contaminants must be removed. Another gas, for example, nitrogen, is often used as a working medium. Even then, the pollutants must be filtered either to return the cleaned gas in the process or to recover valuable products back.
Through the use of the Dedusting system in the industry and in the energy sector could Grit dust content in weight be suppressed considerably since the 80s?
The dust particles contained in the dust-containing gas streams can have usually a particle size range from 0.1 to 1,000 microns.
