Abstract

The invention relates to the technical field of air filter products, in particular to an electrostatic precipitation filter which is used for trapping particulate matters in air efficiently and has an integrated structure and a polarization process for the electrostatic precipitation filter. A main body of the electrostatic precipitation filter is formed by overlaying a plurality of layers of pore plates, wherein array holes through which the air passes are formed in the pore plates integrally; the pore plates are micro-foamed and made of a plastic material added with a polarization reinforcing material, a negative ion emitting material and a magnetic material; closed conducting films for applying high-voltage electric fields are arranged on upper and lower surfaces of each layer of pore plate, and ion emitting devices are arranged in one or more of layers of pore plates; and a high-voltage power supply for supplying power to a high-potential electrode and a low-potential electrode is encapsulated on the lateral surface of an overlaid structure, the overlaid structure and the high-voltage power supply are encapsulated in an outer frame of a protective structure integrally, and the outside of the outer frame is powered by low-voltage direct current or a mains supply. The electrostatic precipitation filter is processed by an on-line polarization technology to form a practical product. Due to the adoption of the technical scheme, the particulate matter filter can eliminate interelectrode sparking and electric shock hidden troubles, is easy to clean, low in wind resistance and high in efficiency, has long service life, can be recycled and is suitable for household and industrial air purification devices.

Description

Technical field: [0001] The invention relates to the technical field of filter products, in particular to an electrostatic dust collection filter with an integrated structure, which is used to purify particulate dust in the air, and can be applied to household air purifiers, central air conditioners, vacuum cleaners, and industrial environment purification. Equipment, especially suitable for occasions requiring low wind resistance and high efficiency. When the orifice plate is made of corrosion-resistant and high-temperature-resistant fluoroplastics, the invention can also be used in corrosion-resistant and high-temperature gas treatment occasions. Background technique: [0002] At present, there are two main ways to purify particulate matter in the air: [0003] 1. The filter composed of folded non-woven fiber filter paper, represented by HEPA (High Efficiency Particulate Air filter) filter, through screening, bridge plug, impact adhesion, electrostatic electret fiber elec...

AI Technical Summary

Problems solved by technology

The disadvantages of HEPA filters are:

[0005] 2) The filter needs to be replaced regularly and cannot be reused, which increases the application cost

[0008] 2) The slight ignition and discharge sound between the electrodes has always been criticized by users, causing concerns about the safety of the product

[0009] 3) Due to the limitation of the breakdown voltage of the open structure, the single filtration efficiency of EPS is low

[0010] 4) Complex high-voltage power supply and high-voltage safety protection measures are required, which increases equipment costs

[0011] 5) The EPS structure, especially the wire-plate structure is very fragile, and it is easy to cause damage during the cleaning process

[0015] 2. The electrodes are in direct contact with the outside of the injection molded orifice plate. In the case of microporous injection molding defects in the orifice plate, it may cause the electrode to discharge to the air or the corresponding inner wall, resulting in odor

[0016] 3. In order to meet the requirements of waterproof and overall structural strength, the adhesive used between the orifice plate layers, especially the two-component adhesive with good bonding performance to PP materials, may be used if the adhesive is not properly operated. The long-term presence of peculiar smell in the filter will cause secondary air pollution

[0017] 4. The electret method mentioned in the patent proposal cannot form charges that can be stored for a long time for the plastic materials mentioned, and these surface charges may disappear after a few days or weeks

[0018] 5. Repeatedly superimposed structures will still produce a large plate capacitance effect. Although high-impedance electrodes are used or bleeder resistors are added to the electrode terminals, there may still be electric shocks in the exposed contact area in the first few seconds.

[0019] 6. It uses the same external high-voltage input method as the conventional ESP power supply method, which requires complex safety circuits in the same way as the ESP working method

[0020] 7. With the combination of non-airtight structure, the electrodes may be exposed to air and water vapor, aging and leakage, which is not conducive to the repeated washing process
