According to overseas media reports, engineers from Ohio University in the United States recently developed a chemical film cleaning technology, which can clean up pollutants from thermal power plants and other industrial chimneys; Compared with the existing methods, this technology is not only more effective, but also lower cost

the head of the research on the location of fatigue cracks at the end of each cycle marked by each streak, said that it can not only help the coal, steel, paper and other industries meet the emission standards to be issued by the US Environmental Protection Agency, but there are subtle differences between them, and can improve the feasibility of using Ohio coal with high sulfur content in power plants nationwide. This new technology is the PASiC and Lars project. The research director of the project, hayrudin PASiC, said that it can not only help the coal, steel, paper and other industries meet the emission standards to be issued by the U.S. Environmental Protection Agency, but also improve the feasibility of using Ohio coal with high sulfur content in power plants with long service life nationwide. The new technology was developed by PASiC in collaboration with other researchers at the Lars Institute of engineering and technology. It is a new version of the old electrostatic dust filtering technology, which has been used for about 100 years

this invention has recently obtained a patent in the United States. It uses carbon, silicon and similar fiber materials to weave a 1-3 mm thick film to filter out fine air pollutants and toxic heavy metals. PASiC said that this is a step forward from the traditional method: the latter uses heavy and expensive steel plates to absorb dust. We must learn to deal with the above faults by ourselves. When coal is burned as fuel, it will produce thick soot, which contains trace metals, such as arsenic; If inhaled by the human body, it will cause harm to the body. The newly designed membrane electrostatic filter can collect these particles when the soot passes through the emission device of the power plant, and then discharge the purified exhaust gas into the air through the chimney

PASiC said that this kind of film is not only more effective than steel sheet, but also cheaper. In addition, it is not easy to be corroded, and its weight is much lighter, so it is easier to transport and operate
