High efficiency particulate air filter (HEPA) 5 adopts no dividing plate form, no baffle filter air quantity under the same pressure drop condition than have dividing plate greatly; The filtrate of high efficiency particulate air filter (HEPA) 5 is a ultra-fine fibre glass paper, reaches more than 99% for 3um particle filter efficiency; If filtrate is a thin glass fiber paper, reach 60%-90% for 3um particle filter efficiency; Filter paper thickness is 0.3-0.6mm; The sectional dimension of high efficiency particulate air filter (HEPA) 5 is consistent with the air channel, and thickness is 150mm; The corrugation density of high efficiency particulate air filter (HEPA) 5 is 30-40 folding/100mm, and bigger corrugation density guarantees lower filtration velocity.
The specific constructive form of control of dust homogenizing plate 4 and high efficiency particulate air filter (HEPA) 5 is (like corrugation density; Depth of folding etc.) concrete parameter is (like hole shape; Percent opening; Apart from the distance of filter etc.) need confirm that numerical simulation technological (like CFD) provides the effective means of design considerations according to field condition and the operating mode of reality.
The filtering purifying equipment pipeline material is the fiberglass with insulating property (properties).If pipeline material is consistent with common air channel to be metallic object, then four surfaces of square tube are collecting plate all, are unfavorable for clean and maintenance.
This system also purifies gaseous contaminant and bacterial virus directly or indirectly when removing particle.At first, high-field electrode discharge generation high voltage electric field, the structure of gaseous contaminant and virus and bacteria can be destroyed under electric field and high-velocity electrons impact; Secondly, a large amount of particles are removed, and gaseous contaminant and virus and bacteria have lost the carrier of relying and relying on, and it threatens the probability of human health to reduce greatly; The 3rd, this system helps improving the raising of follow-up professional device (like photocatalyst and UV purification, charcoal absorption) efficient for the primary purifying of gaseous contaminant and virus and bacteria.
As shown in Figure 2, no pipeline collecting plate 3 is only collected charged particle through current-sharing collecting plate 4, and the length and the layout of high voltage source discharge electrode 2 are different from Fig. 1, directly towards 4 discharges of current-sharing collecting plate.High voltage source discharge electrode 2 is positioned at the conduit section center, and it is axially consistent with pipe lengths, and the electrode left end has the 2-3D distance with Fig. 1 electrode centers, and electrode length has 1-2D (D is a caliber) distance, specifically sees Fig. 2.
Air is through primarily efficient filter, and processes such as electro static filtering are discharged in the enclosure space.The user can select different filter types (as air quality is required height, then select for use Fig. 1 model to adopt ultra-fine fibre glass paper, but cost to be also high according to the character and the interior space instructions for use of interior space particle; As air quality is required, then select thin glass fiber paper for use, but cost decreases).
Although the utility model has been carried out foregoing description in conjunction with accompanying drawing; But the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Under the situation that does not break away from the utility model aim and claim institute protection domain, can also make a lot of distortion, these all belong to the row of the protection of the utility model.
