The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
The utility model indoor fresh air purifier as shown in Figure 1, comprises filter 1, blower fan 8, blast pipe 9 and discharge pipe 7.Blower fan is positioned at blower fan blimp 10, blower fan blimp upper end open.Blower fan is connected with filter by blast pipe, and filter is connected with discharge pipe, and blast pipe is provided with screen pack 4.As shown in Figure 2, filter is tube-in-tube structure, shell 13, large filter cylinder 15 and little filter cylinder 3, consists of, and between shell and large filter cylinder, is provided with air channel 14, between large filter cylinder and little filter cylinder, is activated carbon cartridge 2, in the middle of little filter cylinder, is middle air channel 17.Active carbon filter core 2 consists of graininess cocoanut active charcoal, and the granularity of cocoanut active charcoal is 15～20 orders, specific area 1000～1200m
2/ g, the about 0.90cm of total hole volume
3/ g, the about 0.50cm of micropore volume
3/ g, apparent density 0.45～0.55g/ml, iodine absorption value 900～1000mg/g.Large filter cylinder 15 is comprised of expanded metal lath, micropore expanded metal lath and NACF blanket.The outer attached or included micropore expanded metal lath of expanded metal lath, the outer attached layer of active carbon tapetum fibrosum of micropore expanded metal lath.The mesh diameter of expanded metal lath is 20mm, and string diameter is 2mm, and the diameter of micropore expanded metal lath is 0.5mm.The expanded metal lath skeleton supporting role that has been welded that twists, a cylinder end is that Plate Welding is shut, nozzle circle is equipped with bolt hole in order to capping link.Expanded metal lath is enclosed the fixedly effect of active carbon of having welded that twists of one deck micropore expanded metal lath again, and the outer attached layer of active carbon tapetum fibrosum again of micropore expanded metal lath is pulverized the dust being produced with filter activity charcoal self extrusion, in order to avoid enter indoor generation dust pollution with air-flow.Little filter cylinder 3 is comprised of expanded metal lath and micropore expanded metal lath, and the included or outer attached micropore expanded metal lath of expanded metal lath, plays the fixedly effect of active carbon.The mesh diameter of expanded metal lath is 10mm, and string diameter is 3mm, and the diameter of micropore expanded metal lath is 0.5mm.Filter is divided into two sections, and as shown in Figure 3, the large filter cylinder of two sections connects by bolt 19, connects adpting flange 18 used all with rubber sealing, is conducive to installation, maintenance and the replacing of equipment.Blind flange docks with filter cylinder is overlapping greatly, has effectively solved active carbon in use because the sedimentation space that breaking and Dusting forms causes air cleaning short circuit problem.
The utility model course of work is: under the effect of blower fan 8, by blast pipe 9 by outdoor air filter by suction 1, air is first removed the particle that diameter is large and is entered middle air channel 17 after screen pack 4, the particle of removing between diameter 0.5～2 μ m through too small filter cylinder 3 again, then by active carbon filter core 2, filter absorption and purify, to remove the toxic and harmfuls such as airborne nitrogen oxide, formaldehyde, hydrogen sulfide, ammonia, dioxin.Purified gas enters air channel 14 through large filter cylinder 15, then through discharge pipe 7, flows out, and finally pure air is sent into indoor.Indoor maintenance malleation during filter work, indoor original foul atmosphere is discharged to outdoor by door and window gap or air exhausting device etc., guarantee that outdoor foul atmosphere can not be leaked into indoor simultaneously, thereby reach the object of taking a breath and purifying air.Screen pack is detachably changed after using certain hour.Active carbon filter core in filter also needs periodic replacement, during replacing, only need split filter.
