The American University Daily Science News website reported on June 26 that engineers at Ohio University have developed a technology that can clean up pollutants emitted from thermal power plants and other industrial smoke stacks; this technology is not only More effective and less expensive.
This can be very useful for companies that face federal air quality regulations. This device is called a thin film electrostatic precipitator. Professor Hajruddin Pasic, a professor of mechanical engineering and head of the project's research, said that it can not only help coal, steel, paper, and other industries meet the US EPA's forthcoming emission standards, but also increase the sulfur content. The Feasibility of Using Ohio Coal in National Power Plants. This new technology was developed by Pasic and other researchers at the School of Engineering and Technology Lass. It is a new version of the old electrostatic filter technology, which has been used for about 100 years.
This invention recently obtained a patent in the United States. It uses carbon, silicon, and similar fiber materials to weave 1-3 mm thick films to filter out small air pollutants and toxic heavy metals. Pasic said that this is a step ahead of the traditional method: the latter uses heavy and expensive steel plates to adsorb dust. When coal is burned as a fuel, it will produce thick soot, which contains trace metals such as arsenic, which can cause harm to the body if inhaled by the human body. The newly designed thin-film electrostatic precipitator can collect the particulates as they pass through the power plant's discharge device, and then discharge the purified exhaust gas into the air through the chimney.
Paschi said that the film is not only more effective than steel, but also the price is relatively low. In addition, it is less susceptible to corrosion and lighter weight, making it easier to transport and handle.
