<br>□ Evening News correspondent Yu Ran reports<br> <br>These two days, next to a high school student Huang Si Mian every day after school, a drilling lab playing her invention --PM2.5 air purifier. On a recent innovation lesson, Xiao Huang Huang had to listen to new science and technology teacher talking about PM2.5 particulate matter,nike air max 90, it will have to invent a purifier to prevent PM2.5 into the interior thoughts. Today,http://www.mirai.ne.jp/~m-yoshi/diary/apeboard_plus.cgi/, this prototype instrument was born in the laboratory, it has been recognized by the scientific experts. "I want to get a detection instrument, use the data to test the cleaning effect of this invention." Huang Si Mian told reporters.<br> <br>Innovation Lesson ignite passion invention<br> <br>In the next school, there is a course called "innovation" Course. Each class, Shanghai Invention Association members Huang had a new teacher will introduce students to the recent social hot spots, and to stimulate their enthusiasm invention. At the recent one lesson,piumini woolrich outlet, Huang Si Mian learned "PM2.5" this new term, which refers to the atmosphere in diameter less than or equal to 2.5 micron particles, only one-tenth the diameter of a human hair. Directly into the rear of these particles are inhaled bronchial, triggering including asthma,piumini woolrich outlet, bronchitis and cardiovascular disease and other diseases. Recently,http://tuonela.s138.xrea.com/lightbbs/light.cgi?res=8726,scarpe hogan outlet, China's environmental protection department will "monitor and publish PM2.5" on the agenda, how to control PM2.5, have also been widespread public concern.<br> <br>How can we reduce airborne PM2.5 it? Huang students began to explore at home, her online access to information, to understand a variety of air purification technology and equipment; in school,http://wx.jazzsynth.com/wxcgi/kizai/sunkizai.cgi?mode=form&no=68&page=2, she often had to find a new teacher Huang discussed, devised schemes under the teacher's inspiration.<br> <br>"Have you ever seen a hookah? Pumped past a lot of people smoke, smoke through water filtration, a lot of nicotine, tobacco tar will dissolve in the water." In a discussion on Huang Xiao Huang Speaking of hookah. It can inject water in the air purifier, allowing water to filter out the atmosphere of PM2.5? Huang Si Mian suddenly had an inspiration. However, after the air into the water, the filter effect estimate is limited, how to improve the efficiency of the purifier it? Small yellow into a new round of exploration.<br> <br>Water, fog, ultrasonic filter<br> <br>Yesterday, the reporter walked into the lab to the next school, see a small yellow invention is now taking shape. The air cleaner consists of a housing and a number of devices. NOTE transparent shell in a lot of water, "tank" at the bottom with three submersible pumps oxygen, which together with the three catheter, through the catheter, oxygen pump to draw air purifier around into the water, a large amount of bubbles. Huang Si Mian said submersible aerator pump was originally used to raise ornamental fish, put them in an air purifier is to draw a large number of outdoor air into the water, air and water to make full contact. So that the device becomes a larger version of the "water pipe", a large number of PM2.5 in the air is dissolved in water.<br> <br>Light water filtration deal PM2.5 is not enough, Huang also uses mist filtration. Fog is crystal generated in the air after contact with water vapor and dust,http://store.shopping.yahoo.co.jp/ebest-dvd/0000001169774.html, mist the role of adsorption of dust particles. In order to create "artificial fog", Xiao Huang Internet search repeatedly, finally bought "ultrasonic nebulizer." This equipment was originally installed in the air humidifier inside, she mounted the three ultrasonic atomizer air purifier, and oxygen pump "work together." I saw ultrasonic nebulizer powered water purifier emerge a Unit mist, adsorption air PM2.5.<br> <br>Under the guidance of Huang, Huang Si Mian also purifier in the installation of two high-voltage electrode, negative electrode is energized after, can play the effect of electrostatic precipitator.<br> <br>We hope to use detection equipment Purification<br> <br>Xiao Huang said that after this device design matures,http://blackdog.whitesnow.jp/2/bbs2a.cgi, as it can be installed as wall-mounted air-conditioning in the room wall, connected by conduit on the instrument drawn into the outdoor air, the removal of PM2.5 clean air into the room. This device can also be designed to be more compact and become PM2.5 car air purifier, so that when people travel by car is not contaminated gas inhalation.<br> <br>Huang also envisaged this invention to improve outdoor air purification device. "Vehicle emissions,http://store.shopping.yahoo.co.jp/topism/n-tops-28-topism.html, emissions of coal-fired power plants, the atmosphere of the two main sources of PM2.5. If 'bongs' put cars and coal-fired plants may be able to reduce atmospheric concentrations of PM2.5. "<br> <br>Of course, to make these ideas a reality, Huang Si Mian use experimental data to prove that her invention can remove a lot of the air PM2.5. Preliminary experiments indicate that this device can remove the imported gas fumes. Winter vacation, she was ready to do a more precise experiment: cleaner water into distilled water and let it work for some time after the water sample after evaporation was observed with an electron microscope to detect whether it contains water PM2.5 particles. If so, to prove that the device has a filter PM2.5 function.<br> <br>This invention,http://www.chrisadamsperfumes.com/index.php?item/create_form/1, deputy director of the Shanghai Environmental Monitoring Center Zhangming Xu said, from the principle that this water filter, mist filter, electrostatic dust "three-pronged" is a scientific program, should be able to remove the air portion of PM2. 5, but it's exactly how high purification efficiency, you need to judge the test report. Instruments are used for environmental monitoring center for outdoor PM2.5 detection can not detect the purifying effect of the invention.<br> <br>Huang Si Mian told reporters that she found on the Internet, the price of a single indoor PM2.5 testing equipment of $ 20,000, but the school has no money to buy laboratory. If funding becomes available,http://vegalta7.s156.xrea.com/aska/aska.cgi/www.dasjfheui.com, or provide such testing organizations,air max pas cher, research and development path that "bongs" purifier can continue.<br> <br> Share: welcome to comment I want to comment<br> Microblogging Recommended | hot microblogging today<br>
