In the bag filter bag surface attached to a layer of man-made powder filter aid, PM2.5 average filtration efficiency of up to 99.5%, the most difficult to remove PM2.5 sticky particles were swept away. In yesterday's Zhejiang province "Challenge Cup" university students extra-curricular academic and technological work competition, Ningbo University, five students developed PM2.5 capture device won the first prize, was a business first to sign a cooperation project. It is understood that bag filter is recognized as the most efficient dust collector at home and abroad, is to reduce the most effective PM2.5 equipment. However, the bag filter can only filter non-stick PM2.5 fine particles, there is no way for sticky particles. The Ningbo University PM2.5 this capture device, not only can efficiently filter non-stick fine particles, but also can filter sticky particles. Li Peng, a team of five people told reporters, PM2.5 capture device is actually to improve the bag filter, the principle is not complicated, is to filter the exhaust before the bag surface covered with a layer of unique powder, due to The effect of powder physical filtration and powder adsorption can effectively isolate the sticky particles in the tail gas and change the situation that the original bag filter clogs the scrapped particles when they are sticky particles. According to the experiment, when the bag is not pre-paved, the service life of the bag is only 420 minutes, while the trapping device with a layer of man-made powder filter aid is still intact after 30 cycles and the estimated service life is 2-3 years , The use of cost greatly reduced. At the same time from many experiments, with the addition of powder, the average sub-micron particle filtration can be as high as 99.5%. It is reported that PM2.5 capture device for two invention patents, one of which has been granted a patent, and signed a letter of intent with a company in Jiangsu; the other is being accepted. Currently, under the guidance of their supervisors, the five students have started to study the miniaturization, medium-sized and large-scale installation of the devices. The products they hope to develop can be applied to different fields such as automobiles, ships and industrial furnaces.
