[0055] The specific embodiments of the present invention are described in detail below.

[0056] Unless otherwise specified, the methods used in the following examples are all conventional methods; the materials, reagents, etc. used, unless otherwise specified, can be obtained from commercial sources.

[0057] Example

[0058] The following examples are intended to specifically illustrate the use of the paramagnetic material in the electric field device, the related electric field device and the method according to the present invention.

[0059] This embodiment provides a use of a paramagnetic material in an electric field device, the electric field device having a first pole and a second pole for generating an electric field, and the specific use is: by preparing the paramagnetic material into any one or both of the first pole and the second pole, the power consumption and the temperature rise rate can be reduced during the use of the electric field device. That is, by preparing the paramagnetic material into any one or both of the first pole and the second pole, the power consumption can be greatly reduced when the electric field device is used, and the temperature rise rate can be reduced at the same time.

[0060] In this embodiment, the paramagnetic material is any one or both of aluminum and aluminum alloy.

[0061] The electric field device in this embodiment can be used to purify the gas to be purified containing pollutants. It can be used to purify any one or more of the gas containing volatile organic compounds and the gas to be purified containing particulate matter. When used for purification, the first electrode of the electric field device is used to discharge so that the pollutants in the gas to be purified are charged, and the second electrode is used as an adsorption surface for adsorbing the charged pollutants.

[0062] In this embodiment, the electric field device involved is specifically as follows.

[0063] Figure 1 It is a partial structural schematic diagram of the electric field generating module in the electric field device involved in Example 1;

[0064] Figure 2 is another schematic diagram of a partial structure of the electric field generating module in the electric field device involved in Example 1;

[0065] Figure 3 It is a cross-sectional view of the electric field generating module in the electric field device involved in Example 1.

[0066] To show it more clearly, Figure 1 In the figure, some only show the first pole, some only show the second pole, and some show the complete schematic diagram of the electrode of the first pole passing through the second pole; Figure 2 In the figure, some parts show the complete schematic diagram of the electrode of the first pole passing through the second pole, and some parts show only the second pole; Figure 3 In the figure, part of the cross-sectional view shows only the second pole, and part of the cross-sectional view shows both the second pole and the second pole.

[0067] like Figure 1 and Figure 2As shown, the electric field device has an electric field generating module 100, and the electric field generating module 100 has a first pole 10 and a second pole 20 for generating an electric field, that is, one is used for the above-mentioned discharge function, and the other is used as the above-mentioned adsorption surface, and the first pole 10 and the second pole 20 are insulated and separated, that is, the first pole 10 and the second pole 20 are not in contact with each other for electrical conduction. In this embodiment, the electric field generating module 100 also has a shell 200, and the first pole 10 and the second pole 20 are placed in the shell 200.

[0068] The first pole 10 includes at least one electrode 11, and the second pole 20 has at least one adsorption unit 21. The adsorption unit 21 has at least one hollow tube 211. At least one electrode 11 is inserted in each hollow tube 211. In this embodiment, the number of hollow tubes 211 corresponds to the number of electrodes 11, that is, there are as many electrodes 11 as there are hollow tubes 211, and one electrode 11 is inserted in each hollow tube 211. When the electric field device is used to purify the gas to be purified containing pollutants, the tube wall of the hollow tube 211 serves as the adsorption surface, and the electrode 11 serves as the discharge effect. When the gas to be purified containing pollutants enters from the air inlet of the electric field generating module 100 and then passes through the hollow tube 211, the electrode 11 discharges so that the pollutants in the gas to be purified are charged during the process of being discharged to the air outlet of the electric field generating module 100, and then adsorbed by the hollow tube 211, thereby achieving the purification effect on the gas to be purified.

[0069] Specifically, in this embodiment, the adsorption unit 21 is two 21a and 21b, and the two adsorption units 21a and 21b allow the gas to be treated to pass through in sequence for purification, that is, the two adsorption units 21a and 21b are arranged in sequence from the air inlet to the air outlet of the electric field generating module 100. In this embodiment, the hollow tubes 211 on each adsorption unit are respectively arranged correspondingly: that is, each hollow tube 211 on the adsorption unit 21a has a corresponding hollow tube 211 on the adsorption unit 21b.

[0070] In this embodiment, the electric field generating module 100 further comprises a cathode supporting plate 20 for fixing the electrode 11 , and the cathode supporting plate 20 is disposed between the two adsorption units 21 a and 21 b .

[0071] In this embodiment, the number of hollow tubes 211 corresponds to the number of electrodes 11, and an electrode 11 is inserted into each hollow tube 211. Therefore, in this embodiment, the electrodes 11 are specifically arranged on the cathode support plate 20 as follows: every two electrodes 11 form a group of electrodes, and the two electrodes 11 in the group respectively face the corresponding hollow tubes 211 between the two adsorption units 21a and 21b, and are respectively inserted into the corresponding hollow tubes 211. In this embodiment, the two electrodes 11 in each group of electrodes are integrally formed into an integral electrode group, and the middle part 11a of the integral electrode group is inserted on the support plate 2, and the two ends 11b and 11c of the integral electrode are respectively extended to form two electrodes 11, which are respectively inserted into the corresponding hollow tubes 211.

[0072] In this embodiment, the electric field generating module 100 further comprises an insulating unit 30 , and the cathode supporting plate 20 is supported and fixed by the insulating unit 30 .

[0073] In addition, the shape of the electrode 11 is needle-like, polygonal, burr-like, threaded rod-like or column-like.

[0074] In addition, the cross-section of the hollow tube 211 is circular or polygonal, preferably hexagonal. The hexagonal hollow tube 211 can maximize the effective ventilation area and the adsorption area.

[0075] In this embodiment, the length of the hollow tube ranges from 10 mm to 180 mm, which can avoid electric field coupling during use as much as possible, thereby improving purification efficiency and reducing power consumption.

[0076] like Figure 3 As shown, each adsorption unit has multiple hollow tubes 211, and the multiple hollow tubes 211 of each adsorption unit are arranged in a honeycomb shape. When paramagnetic material is used to prepare any one or both of the first pole and the second pole, the size of the honeycomb can be greatly increased compared with the prior art at the same power consumption, thereby greatly increasing the purification area under the premise of ensuring a certain power consumption. Therefore, in this embodiment, at the same power consumption and the same size of hollow tube arrangement, the length X1 of the honeycomb can be greater than or equal to 2000mm, and the width Y1 can be greater than or equal to 600mm, and the purification area can be increased by more than 2 times compared with the electric field device that does not use paramagnetic materials.

[0077] In addition, on each adsorption unit, in the honeycomb-arranged hollow tubes 211, the center distance between two adjacent hollow tubes 211 ranges from 10 to 100 mm, and the diameter of the inscribed circle of the cross section of the hollow tube 211 ranges from 10 to 400 mm. In this way, as many hollow tubes 211 as possible can be arranged to the greatest extent, thereby ensuring the purification area to a greater extent.

[0078] In addition, with appropriate inter-electrode spacing, better purification effect can be guaranteed. In this embodiment, the inter-electrode spacing of the electric field ranges from 5mm to 100mm. The inter-electrode spacing specifically refers to the minimum vertical distance between the working surfaces of the first pole 10 and the second pole 20 that generate the electric field. For example, in this embodiment, the inter-electrode spacing refers to the vertical distance between the outer surface of the electrode 11 inserted in the hollow tube 211 and the inner wall of the hollow tube 211. In addition, in this embodiment, the tube wall of the hollow tube 211 is placed vertically along the direction of the gas to be treated, that is, when the electric field generating module 100 is in use, the hollow tube 211 is placed vertically, thereby maintaining a uniform electric field, thereby making the purification uniform, thereby further improving the purification efficiency and further reducing power consumption.

[0079] In addition, in this embodiment, the second electrode 20 can be an anode, that is, positively charged, and correspondingly, the first electrode 10 can be a cathode, that is, negatively charged. At this time, after the first electrode 10 is discharged, the pollutants in the gas to be purified are negatively charged.

[0080] In addition, in this embodiment, only paramagnetic material is used to prepare the second pole 20, so that the power consumption can be reduced during the use of the electric field device.

[0081] In addition, in this embodiment, there are more than 100 electric field generating modules, and the multiple electric field generating modules 100 are arranged in sequence along the direction of the gas to be purified. When the hollow tube 211 is placed vertically, the multiple electric field generating modules 100 are arranged in sequence from bottom to top. Within a certain number range, multiple electric field generating modules 100, compared with only one electric field generating module 100, process the same air volume, and the power consumption is greatly reduced. In this embodiment, the number of electric field generating modules is preferably in the range of 2-9.

[0082] In addition, when the adjacent electric field generating modules 100 are arranged in intervals, that is, not arranged in a continuous manner, that is, the adjacent electric field generating modules 100 are not tightly connected, at this time, when processing the same air volume, the power consumption of the interval arrangement is reduced compared with the continuous arrangement. Specifically, for this embodiment, the housings 200 of the adjacent electric field generating modules 100 are spaced apart. In addition, the interval distance of the above-mentioned interval arrangement can not only meet the purification efficiency, but also save space and power consumption.

[0083] Accordingly, in this embodiment, a method for energy saving of an electric field device is also provided, characterized in that: any one or both of the first pole and the second pole are prepared using a material including a paramagnetic material to reduce power consumption during use of the electric field device. Wherein: Similarly, the paramagnetic material is one or both of aluminum or aluminum alloy. The electric field device here refers to the electric field device described above.

[0084] In addition, in the energy-saving method of the electric field device, as described above, multiple electric field generating modules are provided, and the multiple electric field generating modules are arranged in sequence along the direction of the gas to be purified, so as to further achieve power saving and energy conservation; wherein, as described above, the number of electric field generating modules ranges from 2 to 9.

[0085] Moreover, in this method, as mentioned above, by arranging adjacent electric field generating modules with intervals, power consumption and energy can be further saved compared to arranging them in a continuous manner.

[0086] Test Example 1

[0087] In this test example, a gas purification test was carried out on the electric field device in the embodiment. There is one electric field generating module in this test example, and a paramagnetic material is used as the second pole, and a non-paramagnetic material is used as the second pole for comparison. The purification object in this test example is indoor air, and the test objects are PM2.5 and power consumption in the air. The test is shown in Table 1.

[0088] Two adsorption units, each with 100 hollow tubes, the diameter of the inscribed circle of the hollow tube cross section is 22 mm, and the height of each hollow tube is 170 mm. Indoor air is introduced at a wind speed of 3 meters per second, and a 6-channel laser particle counter is used to measure the number of PM2.5 particles at the inlet and outlet.

[0089]

[0090] It can be seen from Table 1 that on the basis of ensuring the dust removal efficiency, when the second pole adopts paramagnetic material:

[0091] (1) The purification efficiency is as high as 99%, but the power consumption is less than half of that of the electric field device with non-paramagnetic materials in the second pole;

[0092] (2) The temperature rise of the second pole within 30 minutes is less than half of the temperature rise of the second pole of the electric field device using non-paramagnetic materials.

[0093] It can be seen that since the second pole is made of paramagnetic material, the power consumption in the use of the electric field can be greatly reduced, the economic burden of users can be reduced, and it is easier to promote it. In addition, the honeycomb area of ​​the second pole can be increased, thereby increasing the purification area as much as possible, so it can also meet the needs of use in more occasions; moreover, the second pole is made of paramagnetic material, and due to the slow heating, the thermal damage to the electric field device is relatively small, which can increase the service life of the electric field device.

[0094] Test Example 2

[0095] In this test example, an electric field device containing different numbers of electric field generating modules in the embodiment was tested. The purification object in this test example was indoor air, and the test objects were PM2.5 and power consumption in the air. Table 2 shows the test results of the electric field generating modules arranged in connection, and Table 3 shows the test comparison results of the electric field generating modules arranged in intervals and connected together.

[0096]

[0097]

[0098]

[0099] In Table 2 and Table 3:

[0100] (1) The aluminum substrate is placed in the electric field device to remove ozone generated during the operation of the electric field device;

[0101] (2) The purification efficiency obtained is the removal efficiency for PM0.3 and PM0.5;

[0102] (3) The voltage displayed corresponding to different numbers of electric field generating modules is the working voltage of each electric field generating module under the corresponding number. For example, in the test of wind speed of 0.23m / s and the number of electric field generating modules is 6, the voltage of 6.5KV means that the working voltage of each electric field generating module is 6.5KV;

[0103] (4) The power displayed is the power consumed by the entire electric field device during operation.

[0104] From the data in Table 2, we can see that:

[0105] (1) Multiple electric field generating modules are more energy-efficient than a single electric field generating module at the same wind speed;

[0106] (2) In both the group without aluminum substrate and the group with aluminum substrate, under the same wind speed, that is, when processing the same air volume, there is a trend that the more electric field generating modules there are, the more energy-saving there is. Moreover, this trend is more obvious when the number of electric field generating modules is in the range of 2-9.

[0107] From the data in Table 3 we can see that:

[0108] The number of electric field generating modules is the same, the voltage is the same, the power and purification efficiency are similar, but the intervals between the electric field modules are compared with the electric field modules connected together, which can handle more air volume;

[0109] In the same space and the same purification area, the more air volume is processed, the more dust is processed per unit volume, which means that a higher power electric field is required to meet the purification needs;

[0110] Table 3 shows that processing more air volume does not require higher power, which means that spacing the electric field modules apart is more energy-efficient than connecting the electric field modules together to process the same air volume.

[0111] In summary, this embodiment verifies that:

[0112] (1) Multiple electric field generating modules are more energy-efficient than a single one, and the appropriate number is in the range of 2-9;

[0113] (2) Multiple electric field generating modules are arranged at intervals, which is more energy-efficient than a connected arrangement.

Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.

In practice, all electric field devices that may generate high power consumption can use paramagnetic materials to prepare any one or both of the first pole and the second pole to achieve the purpose of saving power.

[0116] In the above embodiments and test examples, the second pole is made of paramagnetic material alone to achieve the purpose of power saving.
