As shown in Figure 1, according to the Simplified air purifier of the specific embodiment of the invention according to the size of particle and object loss depth, design layering hinders cleaning system.The concrete structure of this Simplified air purifier comprises: fan and be stratified and set on prefiltering net and the HEPA filter screen of this wind inlet of fan or air outlet, wherein, prefiltering net head is for filtering the first step, intercept some large-scale particles and other fine fibre things, for filtration afterwards lays the first stone, during use, prefiltering net should be placed on the windward end of HEPA filter screen.HEPA filter screen tackles tiny dust contained in the air of filter screen by the flocculent structure of slight fiber, and has the efficient absorption property of active carbon, can be used for purification of air, removes VOC pollutant, has good clean-up effect.
Wherein, fan can adopt turbofan or aerofoil fan, in theory because the wind speed that exists of filter screen reduces, the efficiency of turbofan is higher, but aerofoil fan is more common, the case fan (AVC case fan 12V/0.41A) of general about 10cm can make a pocket Table top type clarifier.The motor of fan adopts controlled pressure-sensitive circuit, changes voltage rotation speed of the fan is regulated by energising, more intelligent., large-scale clarifier can consider that multiple fan is in parallel or larger sized.The fan of Simplified air purifier of the present invention is convenient for changing, larger fan can increase air output and air exchanging rate, can improve filter efficiency, and one of method is that multiple small fan is in parallel, or use the large size turbofan of more violence instead, or similar air blast model is good.
In order to improve the air-out efficiency of fan, prefiltering net and HEPA filter screen should be laid in the air inlet (prefiltering net should be placed on the windward end of HEPA filter screen) of fan.Prefiltering net comprises again: the cotton coarse strainer with being arranged on the cotton leeward end of this coarse filtration of coarse filtration, wherein, coarse filtration cotton can adopt filter cotton felt, utilizes bulky grain to purify optimisation technique, directly can contact filtering for larger particle.Coarse filtration cotton specifically for particle diameter >=5.0 μm, its filter efficiency 90 > E >=70%.Coarse strainer can adopt slightly thick fibrofelt, specifically for particle diameter >=0.5 μm, and its filter efficiency 90 > E >=75%.
HEPA (High efficiency particulate air Filter), the Chinese meaning is high efficiency particle air filter, carry out physical filtering, HEPA filter screen is made up of chemical fibre or glass fibre, by the tiny dust that the flocculent structure interception of slight fiber is contained in the air of filter screen.Conventional specification can receive 99.7% size to be the suspended particulates of 0.3 micron, has good filter effect to chemical fumes, bacterium, dirt particle and pollen.HEPA filter screen can specified size and shape be bought retail on demand.Filter screen is the running stores of clarifier, and the particle stopped all is deposited in the inside, and service life is limited, must timing change.
