The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The invention is described below with reference to specific embodiments in conjunction with the accompanying drawings. Fig. 1-4 are side views of the plasma regeneration assembly 100.
A plasma regeneration assembly 100 according to an embodiment of the present invention will first be described with reference to fig. 1-4. It should be noted that the plasma regeneration assembly 100 according to the embodiment of the present invention can not only filter gases such as air, but also filter some non-conductive liquids, so as to avoid safety risk caused by liquid electrification.
As shown in fig. 1 to 4, a plasma regeneration assembly 100 according to an embodiment of the present invention may include an adsorption filtration module 1, a discharge member 2, and a ground electrode member 3, the adsorption filtration module 1 being located between the discharge member 2 and the ground electrode member 3. The power supply can transmit power to the discharge part 2, and the ground electrode part 3 is not necessarily in contact with the ground as long as the power supply does not directly charge the ground electrode part 3. It can be understood that, in the case that the adsorption filtration module 1 performs filtration for a long time, residual substances (e.g., filter residues) such as VOCs (i.e., volatile organic compounds) may be attached to the adsorption filtration module 1, and the residual substances attached to the adsorption filtration module 1 may reduce the filtration capacity of the adsorption filtration module 1.
When the power supplies transmit power to the discharge element 2, a voltage difference is generated between the discharge element 2 and the ground electrode element 3, so that the discharge element 2 can discharge to the ground electrode element 3. The discharge element 2 may have a sufficiently high voltage (e.g., > 1000V) at which air between the discharge element 2 and the ground electrode member 3 becomes a conductor, so that the discharge element 2 discharges the ground electrode member 3 through the air.
Thereby, when the discharge element 2 discharges to the ground electrode element 3, the substance such as air in the space between the discharge element 2 and the ground electrode element 3 can be charged to be in a plasma state, so that plasma can be formed. At this time, not only the charged discharging part 2 and the ground electrode part 3 can adsorb and adsorb at least part of the residual substances attached to the filter module 1 under the action of electromagnetic force, but also the plasma can adsorb and adsorb at least part of the residual substances attached to the filter module 1, and meanwhile, the air flowing can carry away the residual substances adsorbed by the plasma along with the plasma. The plasma can also decompose the adsorbed formaldehyde into water and carbon dioxide, and exhaust the water and the carbon dioxide into air, so that the environment is protected.
According to the plasma regeneration assembly 100 of the embodiment of the invention, the discharge part 2 can generate plasma substances in the discharge process to decompose and adsorb at least part of the residual substances of the adsorption and filtration module 1, so that the situation that the residual substances on the adsorption and filtration module 1 are too much to reduce the filtration performance of the adsorption and filtration module 1 is avoided, and the adsorption and filtration module 1 has long-term effective filtration performance is ensured.
In some specific embodiments, the discharging member 2 may discharge while the fluid is filtered by the adsorption filtration module 1, and may adsorb the residual substances attached to the adsorption filtration module 1, so as to ensure that the adsorption filtration module 1 has good filtering capability at any time when filtering the fluid.
In other embodiments, the discharging member 2 may also discharge at intervals or when the fluid stops passing through the adsorption filtration module 1, so as to periodically adsorb the residual substances attached to the adsorption filtration module 1, thereby saving electric energy.
In some embodiments, the plasma regeneration assembly 100 is provided with a multi-layer insulation protection device to prevent personnel from directly touching the high voltage parts such as the discharge part 2, thereby ensuring safe use.
In some embodiments, the adsorption filtration module 1 may be a filter screen, the discharge element 2 and the ground electrode element 3 may include electrode plates, each of the discharge element 2 and the ground electrode element 3 may include only one electrode plate, or may be formed by electrically connecting a plurality of electrode plates arranged at intervals, and a fluid channel may be formed between the two electrode plates to allow a fluid to pass through the discharge element 2, so that the fluid can smoothly pass through the plasma regeneration assembly 100.
Specifically, as shown in fig. 1 to 4, the plate of the discharge member 2 may be parallel to the plate of the ground electrode member 3, so that the plate of the discharge member 2 may be directly opposite to the plate of the ground electrode member 3, so as to improve the discharge effect. Meanwhile, the adsorption and filtration module 1 can be opposite to the polar plate of the discharge part 2, so that the contact area between the plasma object generated when the discharge part 2 discharges and the adsorption and filtration module 1 is increased, the adsorption effect of the plasma object on the residual substances on the adsorption and filtration module 1 is ensured, and the electromagnetic adsorption effect of the discharge part 2 and the ground electrode part 3 on the residual substances on the adsorption and filtration module 1 is increased.
In some specific embodiments, the adsorption filter element 1 may be one or more of activated carbon, molecular sieve, MOF (metal-organic framework), and the adsorption filter element 1 contains a catalyst, and the catalyst may be one or more of noble metals Pt and Ba, metal oxides Mn2Ox, CuO, CeO, and the like. The active carbon, the molecular sieve and the catalyst have adsorption effect. In other embodiments, the adsorption filter element 1 may be supported on a substrate, which may be nickel foam, honeycomb aluminum, sapphire, or the like, and the catalyst may be a noble metal such as platinum, palladium, silver, or the like, or a metal oxide such as manganese oxide, cerium oxide, copper oxide, or the like. In still other embodiments, the catalyst may be supported on activated carbon and molecular sieves, and then shaped or supported.

Therefore, the discharge member 2 can discharge to the first ground electrode member 31 and the second ground electrode member 32 at the same time, so that plasma can be generated between the discharge member 2 and the first ground electrode member 31 and between the discharge member 2 and the second ground electrode member 32, and thus, residual substances of the first adsorption and filtration module 11 and the second adsorption and filtration module 12 can be adsorbed at the same time, and the cleaning efficiency is improved.
More specifically, the plasma regeneration assembly 100 may be a plurality of sets disposed side by side and facing each other, and the fluid passes through the plurality of sets of plasma regeneration assemblies 100 in order to improve the cleaning effect on the adsorption filter.
In some specific embodiments, the discharge element 2 is a dc discharge element, that is, a dc power source can supply dc power to the discharge element 2, and the discharge element 2 is a conductor or has a conductor layer, and the conductor layer may be metal or graphite, and may be in a shape of cylinder, thread, strip, irregular structure, etc. This simplifies the structure of the discharge element 2.

In other embodiments, the ground electrode member 3 is attached to the adsorption filtration module 1. Therefore, the ground electrode piece 3 is directly electrically connected with the adsorption and filtration module 1, and the discharge piece 2 and the adsorption and filtration module 1 are integrally used as the ground electrode piece 3, so that the electromagnetic adsorption force of the ground electrode piece 3 on the adsorption and filtration module 1 is improved, and the arrangement space of the plasma regeneration assembly 100 is saved.
Optionally, for example, in an embodiment (only exemplary illustration) where the discharge element 2 is attached to the adsorption filter module 1 or the ground electrode element 3 is attached to the adsorption filter module 1, the discharge element 2 and the ground electrode element 3 are both opened with a fluid flow port adapted to be opposite to the adsorption filter module 1, so as to facilitate fluid to smoothly pass through the plasma regeneration assembly 100 and achieve filtration.
In other embodiments, the discharge element 2 is an ac discharge element or a pulse discharge element, that is, an ac power source can supply ac or pulse current to the discharge element 2, the discharge element 2 has a conductive layer and an insulating layer, the conductive layer can be metal or graphite, and can be in a cylindrical shape, a threaded shape, a strip shape, a special-shaped structure, and the like, the insulating layer can be made of ceramic, quartz, polytetrafluoroethylene, and the like, and the insulating layer is suitable for wrapping the conductive layer. Accordingly, the discharge device 2 generates more plasma substances than direct current power at the time of discharge, and has a stronger adsorption capacity for the residual substances of the adsorption filter module 1.
In other embodiments, as shown in fig. 1, 3 and 4, the discharge element 2 and the ground electrode element 3 are both disposed spaced apart from the adsorption filtration module 1. Therefore, the side of the adsorption and filtration module 1 facing the discharge part 2 and the side of the adsorption and filtration module 1 facing the ground electrode part 3 both have spaces for generating more plasmas, so that the adsorption effect on residual substances on the adsorption and filtration module 1 is improved, meanwhile, a space is provided for the flow of the plasmas, and the plasmas are convenient for bringing the residual substances away from the adsorption and filtration module 1.
