The air purifier is under the action of the fan, the air carrying dust passes through the air channel, the polar plates have the characteristic of a capacitor, each polar plate wrapped by the insulator is positioned in the air bath, and the outer surface of the insulator is provided with a liquid flow. Under the action of a high-voltage direct-current power supply (between about five hundred volts and five kilovolts), due to the characteristics of a capacitor, the outer surface of the insulator is induced with capacitive equivalent heterogeneous charges to form an electrostatic field, and the electrostatic field enables dust in the air to be adsorbed to liquid flow on the outer surface of the insulator and to be carried away from a polar plate along with the liquid flow, so that the air is purified and dedusted, and the air is blown out from an air channel to be relatively clean air; the cleanness of the matched polar plate assembly can be kept; the dust removal is carried out through the liquid flow, and the humidifying effect is also achieved; because the outer surface of the pole plate is wrapped by the insulator, the insulator has the characteristic of not being broken down, the phenomenon that dust is adsorbed on the exposed pole plate to cause discharge to generate ozone is avoided, and the safe use of a user is ensured.
In one example, the reservoir is disposed on top of the mating plate assembly and defines a fluid outlet for applying a fluid stream to the outer surface of the insulator of the plate. Therefore, a liquid curtain can be effectively formed on the outer surface of the insulator of the polar plate, and dust in the air is further promoted to be adsorbed on the liquid curtain and be carried away from the polar plate along with the liquid flow.

When the adsorbed dust left on the polar plates needs to be removed, namely, the dust removal function is started, alternating current is output, when the alternating current is applied to the paired polar plate assembly, the capacitive electrostatic field between the original polar plates is changed into an alternating electric field, the adsorption effect of the electrostatic field fails immediately, the alternating electric field enables the insulator on the outer surfaces of the polar plates to generate repulsion effect on the left attached dust, the dust naturally falls off from the insulator on the outer surfaces of the polar plates, liquid flow is mixed in, and the dust is separated from the polar plates along with the liquid flow, so that the paired polar plate assembly is cleaned.
The matched polar plate assembly is provided with a plurality of pairs, for example, the matched polar plate assembly is set to be 5, 10, 15, 20, 30, 50, 80, 100 pairs or more than 100 pairs, the polar plates are combined with each other to form an array assembly, the outer surface of the power output lead is wrapped with an insulator, the insulator is matched with a high-voltage power supply so that the insulator has the characteristic of not being broken down, the insulator is prevented from being adsorbed on the lead due to dust and generating ozone due to discharge, and the downstream end of the air channel is provided with a clean air outlet so as to send out purified air.

The air to be cleaned with dust is passed through the air passage under air pressure, the counter plate assembly has a capacitor character, the outer surface of the insulator of the plates in the counter plate assembly is in the air bath, and the insulator outer surface is formed with a liquid flow. Under the action of high-voltage direct current, capacitive equivalent heterogeneous charges are induced on the outer surface of the insulator due to the characteristics of the capacitor to form an electrostatic field, dust in the air is adsorbed to the liquid flow on the outer surface of the insulator by the electrostatic field and is carried away from the polar plate along with the liquid flow, so that the air is purified and dedusted, and relatively clean air is blown out of the air channel; the cleanness of the matched polar plate component can be kept; because the dust removal is carried out through the liquid flow, the humidifying effect is also achieved; because the insulator is wrapped on the outer surface of the polar plate and is matched with the connected high-voltage electricity, the insulator is prevented from being broken down, the phenomenon that ozone is generated due to discharge caused by the fact that dust is adsorbed on the exposed polar plate is avoided, and the safe use of a user is guaranteed.
As one example, the application of high voltage dc power is discontinued, high voltage ac power is applied to the mating plate assembly, the mating plate assembly is turned on, the electrostatic field fails, and dust left on the outer surface of the insulator is dislodged and carried away from the plates with the flow of liquid. Wherein the insulator wrapping the outer surface of the pole plate is matched with the high-voltage alternating current so that the insulator is not broken down.
Under the action of high-voltage direct current, the matching pole plate assembly induces the same capacitive heterogeneous charges on the outer surface of the insulator due to the characteristics of the capacitor to form an electrostatic field, and the electrostatic field enables dust in the air to be adsorbed to the liquid flow on the outer surface of the insulator and to be separated from the pole plate along with the liquid flow, so that the air is purified and dedusted; when high-voltage alternating current is applied to the paired polar plate assemblies instead, capacitive electrostatic fields between the polar plates are changed into alternating electric fields, the adsorption effect of the electrostatic fields fails immediately, insulators on the outer surfaces of the polar plates are made to repel the left attached dust by the alternating electric fields, the dust naturally falls off from the insulators on the outer surfaces of the polar plates and is mixed into liquid flow, and the dust is separated from the polar plates along with the liquid flow, so that the paired polar plate assemblies are cleaned.
One example is to collect the flow of liquid through the mating plate assembly; purifying the liquid by a dust-water filter; and purified liquid is supplied to the counter electrode plate assembly through a circulating water pump. So form a circulating water system, recycle liquid carries out dust removal work to the air promptly, effective clean counter electrode plate subassembly.

Referring to fig. 3, the high voltage dc power supply 04 and the high voltage ac power supply 05 are the same power supply, i.e., a high voltage ac/dc power supply, and selectively use dc power or ac power.

In the two embodiments of the air purifier, the power supply, the plate 02 and the insulator 03, which are combined to form the array assembly with capacitive characteristics, and the electrical connection wires of the above elements should be designed to be all elements and components which can be touched with the housing (reliably grounded) of the air purifier and the outside, so that the high insulation and the leakage prevention are maintained, and shielding protection measures and equipment for preventing all electromagnetic wave radiation from being generated to the outside due to direct current and alternating current pulse charges are provided.
Embodiment of air purification method with humidification effect
As shown in fig. 8, the air purification method with humidification effect of the present embodiment includes: guiding the air flow to be purified through an air channel formed by the paired pole plate assemblies by adopting air pressure, wherein each paired pole plate 02 has a capacitor characteristic, and the outer surface of each pole plate 02 is wrapped by an insulator 03; applying a liquid stream to the mating plate assembly to form a liquid curtain on the outer surface of the insulator 03 of the plate 02; by applying a high voltage direct current to the counter electrode assembly, a capacitive equivalent amount of different charges is induced on the outer surface of the insulator 03, creating an electrostatic field that causes dust in the air to be attracted to the liquid curtain and carried away from the insulator 03 on the outer surface of the electrode plate 02 with the liquid flow.
Under the action of air pressure, air to be purified with dust passes through an air channel formed by the paired pole plate assemblies, each paired pole plate 02 has the characteristic of a capacitor under the action of high-voltage direct current, an insulator 03 is wrapped on the outer surface of each pole plate 02, the insulator 03 is matched with the connected high-voltage direct current, so that the insulators are not broken down, the insulators 03 wrapped on the outer surfaces of the two pole plates 02 are induced to generate different charges with the same capacitive quantity to form an electrostatic field, the electrostatic field enables the dust in the air to be adsorbed to liquid flow on the outer surface of the insulator 03 and to be carried away from the insulator 03 on the outer surface of the pole plate 02 along with the liquid flow, and purified clean wet air 07 is sent out from a clean air outlet 13. Thereby effectively realizing the air purification function, the cleaning function of the paired polar plate components and the humidification function at the same time.
As a further optimization of this embodiment, the method further includes: and (3) the application of high-voltage direct current is cut off, high-voltage alternating current is applied to the paired polar plate assembly, the paired polar plate assembly is conducted, the electrostatic field fails, and dust left on the outer surface of the insulator falls off and is carried away from the polar plates along with liquid flow. When high-voltage alternating current is applied to the paired polar plate assembly, due to the characteristics of a capacitor of the paired polar plate assembly, a capacitive electrostatic field between the two polar plates 02 originally becomes an alternating electric field, the adsorption effect of the electrostatic field fails immediately, the alternating electric field enables the insulator 03 on the outer surfaces of the two polar plates 02 to repel the left attached dust, the dust naturally falls off from the insulator 03 and is mixed with liquid flow to separate from the polar plates along with the liquid flow, and further the paired polar plate assembly is cleaned. The insulator is matched to the high voltage to be connected, so that the insulator has a characteristic of not being broken down by the dielectric.
Still further, the air purification method with humidification effect of the embodiment further comprises: collecting the liquid flow through the counter plate assembly; the liquid is purified by a dust-water filter 10; the purified liquid is re-supplied to the counter electrode plate assembly by the circulating water pump 12. Thus, a circulating water system is formed, namely, the liquid is recycled to carry out dust removal work on the air, the dust-water mixture is continuously filtered, and the filtered liquid is applied to the paired polar plate assembly again to remove dust.
The high-voltage direct current is stable direct current or programmable pulse direct current which changes according to a functional relation; the high voltage alternating current is a sine wave or a programmable pulsed alternating current that varies as a function. Experiments prove that the programmable pulse direct current electric energy changing according to the functional relation is adopted to improve the adsorption characteristic of the polar plate, and the programmable pulse alternating current changing according to the functional relation is adopted to control the output of energy in the dust removal and collection process, avoid discharge and generate no ozone.
