The existing air purification products either adopt HEPA filter screens to filter and adsorb particulate matters in the air, the adopted HEPA filter screens mainly aim at PM2.5 and particulate matters with diameters larger than 2.5 microns, and the purification effect of pollutants with diameters smaller than 2.5 microns and even smaller than 1 micron and gaseous pollutants such as formaldehyde is very little. Or adopting ESPCC air purification technology, the benefit of the technology is no consumable, but the filter element needs to be cleaned regularly, otherwise, the purification efficiency cannot be continuously ensured. Even the compound filter core adopting HEPA and active carbon avoids the fact that the active carbon is not saturated in adsorption and the purifying effect on gaseous pollutants such as formaldehyde is reduced.
Disclosure of utility model
The utility model aims to provide a composite multi-effect air purification filter screen, which not only can purify particulate matters PM2.5 and PM10 in the environment, but also can effectively eliminate gaseous pollutants in the air, such as VOC (volatile organic compounds) such as formaldehyde and the like, and can effectively kill bacteria and viruses in the air.

The active carbon layer is used for adsorbing gaseous pollutants and water vapor in the air;
The HEPA high-efficiency filter screen is used for adsorbing organic pollutants and inorganic pollutants in the air;
The dust removal antibacterial layer is added with a catalyst for promoting VOC decomposition, and is used for further removing residual VOC and aerosol in the air which penetrates through the active carbon layer and the HEPA high-efficiency filter screen.
Further, the dust-removing antibacterial layer comprises a dust-collecting electrode made of a metal net, a plurality of groups of protruding discharge electrodes on the inner side of the metal net, and a manganese catalyst layer attached to the outer side of the metal net.
By means of the scheme, through the compound multi-effect air purification filter screen, raw air in the environment can be adsorbed to VOC (volatile organic compounds) such as formaldehyde and water vapor through the active carbon layer, particulate matters in the air can be effectively filtered through the HEPA efficient filter screen, and even if gaseous pollutants and tiny particulate matters exist in the air after the active carbon layer and the HEPA efficient filter screen or aerosol containing viruses passes through the electrostatic dust collection metal mesh and the manganese catalytic substance of the last layer, the air can be further eliminated. Such structure, owing to preposed active carbon and HEPA high efficiency filter screen, avoided adopting ESPCC air purification technique air purification mode alone, the filter screen will collect the dust soon, need often wash the problem of filter screen, in addition, owing to adopted detachable construction, the metal mesh collection dirt is saturated after, just need take out to clean, very big reduction user's use cost and maintenance cost.

Detailed Description
The following describes in further detail the embodiments of the present utility model with reference to the drawings and examples. The following examples are illustrative of the utility model and are not intended to limit the scope of the utility model.
Interpretation of the terms
An air purifier: the air purifier is also called as an air cleaner, an air freshener and a purifier, and can adsorb, decompose or convert various air pollutants (generally including PM2.5, dust, pollen, peculiar smell, decoration pollution such as formaldehyde, bacteria, allergen and the like), and the product for effectively improving the air cleanliness is mainly divided into household, commercial, industrial and building.
HEPA (HIGH EFFICIENCY particate AIR FILTER), chinese means a high efficiency air filter, a filter screen meeting HEPA standards, and an effective rate of 99.998% for 0.1 micron and 0.3 micron, the HEPA screen being characterized by air passing through but fine particles not passing through. It has particle eliminating efficiency over 99.7% and is effective in eliminating fume, dust, bacteria and other pollutant in the diameter over 0.3 micron (1/200 of the hair diameter). (the smoke particles produced by smoking are 0.5 microns in diameter). It is the most efficient filter material internationally recognized. Is widely applied to high-clean places such as operating rooms, animal laboratories, crystal experiments, aviation and the like.
1. The special seamless sealing technology has better sealing effect, longer duration and difficult leakage;
2. The two sides of the filter material are provided with metal protective nets.
3. Other various thicknesses of 50mm,69mm,90mm, etc. may be provided.
4. MPPS efficiency is counted in scanning of laser by stage: 95% -99.999995% (EN 1882).
5. Filtration grade: H11-H14, U15, U16 (EN 1822).
ESPCC air purification technology (Electronic Static Precipitator Coupled Catalyst), abbreviated as ESPCC technology, also called high-voltage electrostatic dust removal and coupling catalysis technology, refers to the adoption of a high-voltage electrostatic precipitator, and can adsorb particles with the particle size of more than 0.01 microns. Bacteria are particles with a particle size of 0.5-5 microns or more, and viruses with an average diameter of 0.1 microns are often attached to large particles. When passing through the electrostatic field, viruses are caught by the electrostatic field and adsorbed on the electrostatic field.
Active manganese, catalytic oxidation and formaldehyde decomposition. The research shows that the active manganese has rich unsaturated electron holes, can activate oxygen in air and water to generate active oxygen and active hydroxyl, and can decompose formaldehyde into water and carbon dioxide. The mechanism of formaldehyde removal is completely different from that of activated carbon, which has life limitation, and activated manganese is used as a catalyst, so that formaldehyde can be continuously removed theoretically without attenuation. The formaldehyde removing capability of the air purifier can be obviously improved by using the material in the air purifier. The method is specifically applied to active manganese formaldehyde removal particles, active manganese filter screens and active manganese filter cores.
Referring to fig. 1 and 2, this embodiment provides a composite multi-effect air purification filter screen, which adopts a cylindrical detachable structure, and includes an outermost active carbon layer 1, an intermediate HEPA high-efficiency filter screen 2, and an innermost dedusting and antibacterial layer 3.
The activated carbon layer 1 is used for adsorbing gaseous pollutants and water vapor in the air.
The HEPA high efficiency filter screen 2 is used for adsorbing organic pollutants and inorganic pollutants in the air.
HEPA filter screens include four filtering mechanisms.
The first is a blocking mechanism, which has an effect on large particles.
The second mechanism is gravity influence, small-volume and high-density particles, the movement speed of which can be reduced when passing through a HEPA filter screen, naturally settle on the HEPA, and the process is similar to the process of sediment in water settling downstream of a river.
A third mechanism of HEPA screens is airflow effects. Because the HEPA filter screen is woven unevenly, constitute a lot of air eddies, the ultra-small particle thing receives the influence of this cyclone and adsorbs on the HEPA filter screen, accomplishes the filtration intention.
The fourth filtering mechanism is that the ultrafine particles impact on HEPA filter screen fibers under the effect of Brownian motion and are influenced by Van der Waals force to be filtered.
The dedusting and antibacterial layer 3 is added with a catalyst for promoting VOC decomposition, and is used for further removing residual VOC and aerosol in the air which passes through the active carbon layer 1 and the HEPA high-efficiency filter screen 2.
In this embodiment, the dust-removing and bacteria-inhibiting layer 3 includes a dust-collecting electrode 31 made of a metal mesh, a plurality of sets of protruding discharge electrodes 32 on the inner side of the metal mesh, and a manganese catalyst layer 33 attached on the outer side of the metal mesh.
When the composite multi-effect air purification filter screen is placed in the air purification device, an electrode contact at the top of the filter core is connected with a power supply of the air purification device, a high-voltage electrostatic field is formed between dust collecting electrodes 31 of an inner dust removal antibacterial layer 3 during operation, a discharge electrode 32 can continuously discharge, polluted air is ionized and added with electric charge when passing through the high-voltage electrostatic field, and therefore particles (containing bacteria and viruses) are adsorbed onto the dust collecting electrodes 31 of the dust removal antibacterial layer 3 in a charged mode. After the air purifying device stops working, no high-voltage electrostatic field is generated, and no electric charge is added to the particulate matters in the air. After the metal mesh is saturated with adsorbed dust, the composite multi-effect air purification filter screen can be taken out, and the dedusting and antibacterial layer in the filter screen can be detached for cleaning.
The composite multi-effect air purification filter screen is placed inside an air purification device, when the air purification device works, unpurified air passes through the activated carbon layer 1, and pollutants in volatile organic compounds formaldehyde, toluene, hydrogen sulfide, chlorobenzene and air can be removed by utilizing the efficient adsorption performance of activated carbon. Air filtered by the activated carbon layer 1 can enter the HEPA efficient filter screen 2, and when the air passes through the HEPA efficient filter screen, smoke, dust, pet dander, PM2.5 and other particles harmful to human bodies, even part of mould, bacteria and viruses, are vast majority. The fractions are filtered out. After the air passes through the HEPA high-efficiency filter screen 2, even if the air has residual tiny particles, when the air approaches the dust-removing antibacterial layer 3 with a high-voltage electrostatic field, electric charges are added, so that the air is adsorbed on the metal screen. Meanwhile, the manganese catalyst layer 33 of the dust removal antibacterial layer 3 is combined, and ozone generated in the high-voltage electrostatic ionization process can also perform catalytic reaction on formaldehyde, benzene series and the like which are not thoroughly eliminated, so that harmful gases such as formaldehyde and the like can be continuously converted into harmless carbon dioxide and water at room temperature.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, and it should be noted that it is possible for those skilled in the art to make several improvements and modifications without departing from the technical principle of the present utility model, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
