The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the specific embodiment of the present utility model.
As Figure 1-3, the wet curtain of a kind of air filtration that the utility model provides, comprises for the air of process being lowered the temperature with the wet curtain layer 1 of humidification, for the air of process being carried out to filtered air filter course 2 and the installation frame 3 for wet curtain layer 1 and air filtration layer 2 are fixed together.
Wherein, wet curtain layer 1 comprises wet curtain 13 and wet curtain fixed frame 11, on wet curtain 13, is formed with honeycomb hole 14, and wet curtain 13 is arranged in wet curtain fixed frame 11.
The relative both sides of installation frame 3 are respectively arranged with peristome 31, and air filtration layer 2 is fixedly mounted in installation frame 3, and wet curtain fixed frame 11 is also fixedly mounted in installation frame, and is positioned at the upstream position of air filtration layer 2.
That is, the wet curtain of this air filtration comprises wet curtain layer 1, air filtration layer 2 and installation frame 3.
Wet curtain layer 1 is for the air of process is lowered the temperature and humidification, and it comprises wet curtain 13 and wet curtain fixed frame 11, and wet curtain 13 is arranged in wet curtain fixed frame 11.On wet curtain 13, be formed with honeycomb hole 14, be the cellular irregular through hole being arranged on wet curtain 13 and be referred to as honeycomb hole 14, it passes through for empty G&W.Wet curtain 13 is honeycomb, and it is formed by body paper processing.
Air filtration layer 2, filters for the air to process.It can be for arbitrarily can be to airfiltering member.
Installation frame 3, for wetting, curtain layer 1 and air filtration layer 2 are fixed together.The both sides that installation frame 3 is relative are provided with peristome 31, for circulation of air.The curtain 13 that first will wet is arranged in wet curtain fixed frame 11, then air filtration layer 2 and wet curtain fixed frame 11 are fixedly mounted in installation frame, and makes wet curtain fixed frame 11 be positioned at the upstream position of air filtration layer 2, both be arranged in parallel with peristome 31.Above-mentioned upstream position refers to relative air flowing through channel, air is first through wet curtain layer 1, after through air filtration layer 2, therefore wet curtain fixed frame 11 and wet curtain 13 are positioned at the upstream position of air filtration layer 2, air filtration layer 2 is positioned at the downstream position of wet curtain fixed frame 11.
In use, by water pump, water is introduced to the top of wet curtain 13, it is sprayed, on the surface of wet curtain 13, form moisture film, under the blast producing at blower fan, air passes wet curtain 13 by the peristome 31 of a side, the wet surperficial formed moisture film of curtain 13 absorbs airborne heat and forms latent heat, makes the air cooling-down humidification that passes through, and airborne a part of particle is played to suction-operated, by flowing water, taken away, play the effect of preliminary purification air.
Air through wet curtain 13 cooling humidifications passes through air filtration layer 2 again, air filtration layer 2 utilizes the particle in Electrostatic Absorption and ionized air or utilizes the fiber interweaving in a jumble to form without several barrier etc. scheme particle, with filtered air particle, reach the object purifying air.
Thus, the wet curtain of air filtration that the utility model provides, by wetting, curtain layer 1 and air filtration layer 2 are set to one, can utilize wet curtain layer to the air humidification of lowering the temperature, utilize air filtration layer 2 to remove airborne molecule, play smart filter effect, and simple in structure, practicality easy to prepare.An equipment possesses cooling humidification and air filtering function simultaneously, can reduce purchase of equipment cost, economizes on resources and electric energy, and it is suitable for large, medium and small indoor place.
Preferably, as shown in Figure 4, air filtration layer 2 is for being netted static electret screen pack 21.Static electret screen pack 21 can standby storage space electric charge and dipole electric charge, by static catch and ionized air in particle, reach the effect of filtered air, and filtration resistance is very little.
