In the bag filter bag attached to the surface of the powder layer of artificial aid, PM2.5 average filtration efficiency as high as 99.5 percent, the most difficult to clear sticky particles PM2.5 were also swept away the light. In Zhejiang Province, which ended yesterday, "Challenge Cup" College Students Extracurricular Scientific and Technological Works competition, Ningbo University, five students developed PM2.5 traps won the first prize, was the first to sign a cooperation project enterprise.


It is understood that the baghouse is widely recognized as the most efficient dust collector, is the most effective device to reduce PM2.5. But only filter baghouse fine particles PM2.5 in non-stick, no way for fine particles stick. The Ningbo University, this PM2.5 trapping device, not only can efficiently filter stick fine particles can also filter fine particles stick.


Five-man team of Lee Han Peng told reporters, PM2.5 traps it is actually bag type dust collector to be improved, the principle is not complicated, is in the bag filter exhaust front surface covered with a layer of powder unique, because the effect of the powder and the powder physical filtration adsorption, effectively cut off from the exhaust sticky fine particles, changing the original case baghouse a sticky particles will plug scrapped the status quo. According to the experiment, when the powder is not pre-shop, bag life of only 420 minutes, while the external layer of filter aid artificial powder collection device, after 30 times cycle test is still intact, expected useful life 2-3 years , the use of low cost. Simultaneously from several experiments to see, plus the powder, the particles of submicron average filter can be as high as 99.5%.
It is reported that, PM2.5 traps applied for two patents, one of which has been granted a patent, and with an enterprise in Jiangsu signed a letter of intent; another one is acceptance.


Currently, five students in the teacher's leadership, began to study the device miniaturization, medium and large-scale, they want to be able to use research and development of products to the automotive, marine, industrial furnaces and other different fields.
