Description

Composite filter net and air purifier
Technical field
This utility model relates to air purification field, relates more specifically to composite filter net and uses the air purifier of composite filter net.
Background technology
At present, homes and offices generally uses air purifier to the pollutant removing in air.Pollutant in air mainly have suspended particulate contaminants and gaseous contaminant.
Suspended particulate contaminants is mainly airborne particulates.Airborne particulates can be divided into dust, cigarette, ash, mist, mist, haze, flue dust, smog etc. by morphological characteristic.Additionally, in specific production, life area, suspended particulate contaminants is also possible that dust, fiber, antibacterial, virus etc..The particle diameter suspended particulate contaminants less than or equal to 10 microns is referred to as PM10, because these suspended particulate contaminants can be sucked by human body, therefore also referred to as " pellet ".Pellet can be deposited on the position such as human respiratory tract, alveolar with suction, thus diseases induced.The diameter of suspended particulate contaminants is the least, and the position entering respiratory tract is the deepest, endangers the biggest.Along with the diameter of suspended particulate contaminants is further reduced to less than or equal to 2.5 microns (i.e. PM2.5), the overwhelming majority in these suspended particulate contaminants can enter human lung, is therefore also referred to as " can enter lung particulate matter ".
Gaseous contaminant mainly includes carbon monoxide, carbon dioxide, formaldehyde and organic vapor etc..They are essentially from construction material (formaldehyde), photocopier (ozone), smoke from cigarette (nicotine), cleaning agent (formaldehyde), solvent (toluene) and combustion product (oxysulfide, lead) etc..Major part in them can be inhaled into pulmonary and cause multiple pulmonary disease.
Existing air purifying filter mesh often utilizes and carried out air filtering for the multiple filter courses filtering different pollutant component.Fig. 1 illustrates the structure disassembly diagram of a kind of typical multiple field air purifying filter mesh 100.According to a kind of existing technology, multiple field air purifying filter mesh 100 can include filter course 101, Electrostatic Absorption layer 102 and photocatalyst layer 103.
According to a kind of existing technology, filter course 101 can be the activated carbon utilizing absorption principle to filter air, or carries out the high-efficiency particulate air filter (HEPA) of mechanical filtration.Dust, abnormal flavour and the part antibacterial that filter course 101 was mainly used in air filtering.
According to a kind of existing technology, multiple field air purifying filter mesh 100 also includes Electrostatic Absorption layer 102.Electrostatic Absorption layer 102 can include discharge electrode and receiving electrode.When two interpolars input high voltage direct current, produce anions and canons at this two interpolar.Under the effect of the electric field force of two interpolars generations, produced anions and canons acts on the minute dust in the air flowing through two interpolars and/or antibacterial, and makes these minute dust and/or antibacterial be attracted on discharge electrode and receiving electrode.By this process, Electrostatic Absorption layer 102 may filter that the antibacterial in air, dust, smog etc..
Additionally, according to a kind of existing technology, multiple field air purifying filter mesh 100 may also include photocatalyst layer 103.Photocatalyst layer 103 is the filter course that surface spraying has photocatalyst of titanium dioxide material.When coordinating uviol lamp to use, surface, photocatalyst top layer 103 occurs excitation to produce and have Strong oxdiative and the electronics of reducing power and hole.Water on photocatalyst layer 103 surface of these electronics and cavity energy and absorption and oxygen react, and generate hydroxyl free radical.The chemical bond of all composition organic molecules almost can be cut off and be decomposed into water and carbon dioxide by the hydroxyl free radical with Strong oxdiative ability.Therefore, the harmful chemical in air, odorant can be decomposed or harmless treatment by photocatalyst layer 103.
In actual applications, according to actual operating environment requirements, multiple field air purifying filter mesh 100 generally includes at least two-layer in filter course 101,102,103.In a pervasive environments, multiple field air purifying filter mesh 100 at least includes filter screen 101.
Regrettably, existing multiple field air purifying filter mesh described above has the disadvantage that
First, above-mentioned multiple field air purifying filter mesh is the most dirty and breed bacteria, but, relation due to material nature, filter course is all unsuitable for being washed with water cleaning and Reusability, and therefore, user can only change filter course, the most both it was not convenient to use, added again use cost.
Second, technique at the surface spraying photocatalyst of titanium dioxide material of photocatalyst layer makes photocatalyst of titanium dioxide material limited with the contact area of gas, and the photocatalyst of titanium dioxide material sprayed easily peels off from the surface of photocatalyst layer, thus limits purification efficiency, shortens service life.
3rd, the filtration to PM2.5 is only capable of reaching about 90%, it is impossible to meet the Indoor Air Quality standards of increasingly stringent.
Additionally, for existing air purifier, when indoor/outdoor temperature-difference is bigger, the temperature of the air of air purifier conveying differs bigger with room temperature, it is impossible to meet the needs of indoor orthobiosis, and energy loss is the biggest.
Therefore, a kind of easy cleaning is replaced, use cost is low and purification efficiency is high airstrainer and air purifier are present needed exist for.
