Aramid Bag Dedusting Technology Helps Air Pollution Control

In the spring of this year, there were frequent dust storms in the north of China. The concentration of PM10 in some periods exceeded 350 micrograms per cubic meter, and the Beijing area even reached 1000 micrograms per cubic meter, which reached serious pollution.

PM2.5 is not far away, and PM10 is coming strong again. The severe air pollution situation in China is obvious to all.

The Meteorology Department explained that the decline in air quality was related to dust and dust from the central part of Mongolia.

However, from the sources of PM10 in recent years, urban dust is only a part of the cause of PM10, and its main source is the emissions of human in industrial production. Among them, the ultra fine particles directly discharged from the thermal power plant, steel plant, petrochemical plant, cement plant and other industries are the most serious air pollution.

It is understood that the temperature of industrial smoke and dust is usually higher than 150 degrees Celsius or even more than 300 degrees Celsius. Conventional filter material is simply unbearable and must be treated with high temperature resistant filter material.

After seeing the great importance of environmental protection and the great demand for air filtration materials, Yantai Taihe new material Limited by Share Ltd continues to carry out technological innovation according to market demand, and introduces many kinds of differential filtration aramid fiber.

Song Xiquan, general manager, said that filtration

It has excellent high temperature resistance, flame retardancy, excellent spinnability and processability. It accords with the emission and atmosphere of industrial waste gas in China at present.

The urgent need and the public's strong desire to govern PM10 and PM2.5.

At present, the filtration of aramid fiber and high efficiency energy saving filter fiber in Tai He new material production can be processed into needle punched nonwovens and woven filter cloth according to the different working conditions and filtering accuracy requirements. The aramid filter dust bag can maintain excellent wear resistance and flexural performance at 220 degree working condition. Its comprehensive dust removal efficiency is as high as 99.9999% in the laboratory and 99.99% in practical applications. Even if the particle size of 1 micron particles can reach 98%~99%, it is the best comprehensive high-temperature filter bag.

Now, the air pollutant emission standards will be increasingly stringent, and the task of energy saving and emission reduction is becoming increasingly arduous. The aramid materials with high temperature and chemical resistance are urgently needed to filter and purify high temperature waste gas, dust and sewage, and the application of aramid materials will have a greater breakthrough.

According to Song Xiquan, general manager of the company, Taihe new material is also actively promoting the popularization of high efficiency aramid bag type dust removal technology. At present, the product market has shown a significant growth trend.

According to introducing, at present, Taihe new material has made a series of important achievements in the research and development of aramid fiber and its industrialization application.

Among them, the super fine aramid fiber has the leading technology in the world, and it has obvious filtration efficiency for fine particles. It is the representative product of "PM2.5 industrial protective fiber" in the trend of 2014/2015 fiber in China.

As we all know, the difficulty in the development and application of high-performance fibers, including high temperature filtration, including aramid fiber, is to improve the accuracy of filter bags while reducing the resistance to running. This is a contradiction. However, in the situation of strict environmental protection, it is necessary to achieve an optimal balance for precision filtration.

At present, Taihe new material is carrying out related technical research. The upcoming differential filtration aramid fiber is expected to solve this problem.
