Under normal temperature and pressure, the molecular structure is volatile, and it quickly decomposes into oxygen (O2) and a single oxygen atom (O). Ozone is an ideal green oxidant because of its strong oxidizing properties and can decompose itself in water in a short time without secondary pollution. It has fast, environmentally friendly and safe effects on deodorization, decolorization, sterilization and removal of organic matter. Therefore, ozone is widely used in various industries, including but not limited to environmental protection, water treatment, pharmaceutical, food, chemical, agricultural, paper and other industries.

Figure 10).

Plate Ground Electrode (Component)

The plurality of stacked plate ground electrodes 22 in accordance with some embodiments of the present invention will be described with continued reference to the drawings. In the embodiment shown, the plate ground electrode (module plate) 22 may comprise a one-piece or one-piece body. The body of the plate-type ground electrode 22 may be made of aluminum alloy coated with nano-ceramic material.

In some embodiments, the plurality of stacked plate ground electrodes 22 may include a first end ground electrode 222 (a first module plate) having an air inlet 2220' therein, a first end ground electrode 222 having an air outlet 2240' therein, a second Two end ground electrodes 224 (second module board) and at least one middle ground electrode. In the embodiment shown, the intermediate ground electrodes include a first intermediate ground electrode 226 (third module board) and a second intermediate ground electrode 228 (fourth module board). In the embodiment shown, the same features of the ground electrodes may be denoted by common reference numerals.

In the embodiment shown, the ground electrodes at different locations may have different internal structures or orientations related to fluid distribution, as will be explained further below.

A) Flow structure of cooling fluid

11A-11B and FIGS. 13-18 in particular, each plate-type ground electrode 22 may include a plurality of vertical fluid passages 2202, a communicating elongated groove 2206 communicating with the two fluid passages 2202 at the top, and communicating two fluid passages 2202 at the bottom. The communicating elongated grooves 2206 of the fluid passages. In the embodiment shown, the plate ground electrode has 4 vertical fluid channels. Each plate ground electrode 22 may also include plugging elements, such as plugging screws, for plugging the machined holes 2208 of the fluid channel 2202 at the top and bottom ends. In the embodiment shown, the first, second, and middle plate electrodes may have the same vertical fluid passages, such as 2242, 2262, 2282, and the like. The ozone generating unit is provided with one or more inflow ports and one or more outflow ports (not shown) for cooling fluid at the bottom of the plurality of stacked plate-type ground electrodes. In the embodiment shown, the fluid passages described are all formed in a one-piece plate body and can be end closed by means of blocking elements that close off the machined holes 2208 . Furthermore, the fluid passage can form a tortuous flow path in the ground electrode by means of the communicating elongated grooves. It should be noted that, in the illustrated embodiment, it is a continuous elongated groove, that is, it can be open (not penetrated) on one side (surface), but can be closed by means of overlapping adjacent ground electrodes. However, in some embodiments, it may be a through-connecting long hole.

In the illustrated embodiment, the plurality of inflow ports and the plurality of outflow ports of the ozone generating unit are alternately arranged at the bottom thereof along the stacking direction of the plurality of stacked plate-type ground electrodes. Accordingly, corresponding outflow ports and inflow ports are alternately provided in the corresponding cooling fluid distribution system 50 (as explained below). In the embodiment shown with 30 modular plates, there are 6 inflow ports and 6 outflow ports, respectively. Here, for example, the first end electrode 222 has an inflow port, and the inflow port is provided every 5 module boards, and the second end electrode 224 has an outflow port, and the outflow port is provided every 5 blocks.

Reference is made in particular to the embodiments of Figures 15-17. As shown in FIG. 17 , on the inner surface of the first end ground electrode 222 (the surface facing the middle ground electrode), the left side of the lower communication elongated groove 2206 , here the inflow end, has a communication hole 2203 . Correspondingly, although not shown, a corresponding communication hole may be provided on the surface of the adjacent (first) intermediate ground electrode 226 facing the ground electrode 222, that is, on the left side of the lower communication elongated groove 2206 (according to the figure 15 orientation). Thereby, the cooling fluid flowing into the ground electrode 222 through the inflow port can flow into the ground electrode 226 at the same time. As shown in FIG. 15 , the surface of the first intermediate ground electrode 226 facing away from the first end ground electrode 222 can communicate with the right side of the elongated groove 2206 at the bottom, here is the outflow end, and has a flow hole 2203 . As shown in FIG. 16 , the surface of the second intermediate ground electrode 228 facing away from the first end ground electrode 222 can communicate with the left side of the elongated groove 2206 at the bottom, here is the inflow end, and has a flow hole 2203 . Although not shown here, the surface of the second intermediate ground electrode 228 facing the side facing away from the first end ground electrode 222 may communicate with the right side of the elongated groove 2206 in the lower part (in the orientation of FIG. 16 ), here For the inflow end, there is a flow hole 2203 which communicates with the flow hole on the inner side surface of the first intermediate ground electrode 226 similarly as previously described. Although not shown, in some embodiments, the inner surface of the second end ground electrode 224 (facing the surface of the first end ground electrode 222 ) may have a flow-through configuration similar to the second intermediate ground electrode 226 .

Thus, in the embodiment shown, due to the sequential stacking of the first and second intermediate ground electrodes, two adjacent module plates form an arrangement of inflow and outflow communication holes that are shared in sequence. However, it is conceivable that, for example, based on different configurations of the inflow port and the outflow port, there are other communication hole arrangements, or no communication hole arrangement.

B) Flow structure of reactive gas

15-17 in particular, on the inner surface of the first end ground electrode 222 (the surface facing the middle ground electrode), the first and second middle ground electrodes 226, 228 face away from the surface of the first end ground electrode 222 A first recessed region 2200 is formed. Although not shown in detail, on the inner surface of the second end ground electrode 224 (the surface facing the middle ground electrode), the first and second middle ground electrodes 226 , 228 are formed on the surface facing the first opposite end ground electrode 222 There is a second recessed area 2200'. In the illustrated embodiment, the first recessed region 2200 is deeper than the second recessed region 2200'. The recessed regions are configured to accommodate high voltage discharge cells located between adjacent ground electrodes, and accordingly define a flow area of the reactive gas. In the illustrated embodiment, the module board further has a receiving groove 2201 at the top on the surface provided with the first concave area, so as to receive the joint portion of the high voltage discharge unit. An annular sealing groove and an annular seal (not shown) located therein may also be provided on the outer periphery of the recessed area.

Continuing to refer to FIGS. 15-17 , the first middle ground electrode 226 and the second middle ground electrode 228 include first and second long holes 2260 and 2280 penetrating through the two sides, respectively. The first and second end ground electrodes include first elongated grooves 2220, 2240 and second elongated grooves 2221 (not penetrating) on two sides, respectively. Thus, the first elongated hole and the first elongated groove form an elongated air intake cavity located on one side. The second elongated hole and the second elongated groove define elongated exhaust cavities on opposite sides. The air inlet 2220' in the ground electrode 222 at the first end communicates with the first elongated groove 2220 and then the elongated air inlet cavity. The air inlet 2240' in the second end ground electrode 222 communicates with the second elongated groove (not shown), and then the elongated air inlet cavity. In the preferred embodiment shown, there is also a vertical (machined) hole (which is blocked by the blocking element) at the position of the elongated hole, the elongated groove, so that the vertical machined hole also forms part of the air cavity (best shown in Figures 11A-11B). In the illustrated embodiment, in (the body of) the module plate, elongated holes or elongated grooves are located in said recessed areas 2200, 2200'.

In addition, in embodiments of the present invention, each ozone generating unit may have numerous gas flow passages in and between the intake cavity and the exhaust cavity. In some embodiments, in the recessed region, a plurality of planar (micro) bosses 2204 and grooves 2205 between the planar bosses 2204 may be formed transverse to the slotted holes/elongated grooves, whereby the planar projections Stage 2204 may abut the media plate with its flat top surface. In an advantageous embodiment, planar (micro) bosses with very low height and high aspect (width-to-height) ratios may be provided, so that recesses 2205 may advantageously be provided to form a flat aspect ratio with the dielectric plate Extremely high gas (micro) flow channels, which advantageously overcomes the dilemma of isolation of adjacent gas flow channels and effectively improving gas contact and thus reaction efficiency. In some embodiments, the aspect ratio of the planar boss is, for example, 2:1 to 50:1, preferably 5:1 to 50:1, more preferably 10:1 to 30:1, and the gas flow channel (groove ) has an aspect ratio of, for example, 10:1 to 200:1, more preferably 20:1 to 200:1, more preferably 50:1 to 150:1.

In the illustrated embodiment, in the first recessed region 2200 of the first end ground electrode 222 and the first and second intermediate ground electrodes 226, 228, a plurality of planar bosses 2204 and a plurality of planar bosses 2204 are formed. groove 2205 between.

Groove 2205.

Here, the structure of the plane bosses and grooves is extremely advantageous, and the plane bosses can be made very short, so that the height of the flow channel is small and the width is large, and at the same time, each flow channel can be guaranteed. The dimensions are very uniform and the contact sealing of the flat boss is uniform and good, which can obtain excellent gas generation effect and cooling effect.

In the preferred embodiment shown, the recessed regions may have over-roundings 2209 at the corners. This surprisingly increases yield and improves heat distribution. While not being bound by theory, it is speculated that this may be due to reduced tip discharge to the corners of the dielectric plates.

With particular reference to Figures 11A-11B, the dielectric plate 216 can be configured to extend beyond the area of the planar boss/groove into the elongated hole/slot or elongated air cavity to form the protrusion 23, which surprisingly increases throughput and Improved heat distribution.

A number of different embodiments are envisioned in which different plate-type ground electrode assemblies are formed from different module plate configurations, stacking patterns, and fluid flow patterns.

For example, in one embodiment there are different gas flow directions of the illustrated embodiment, so that the second module plate 224 is here as the end electrode of the inlet end and the first module plate 222 is here as the outlet end.

For example, in one embodiment, one or both of the end module plates may be configured to not participate in corona discharge, ie, only provide first and/or second "blind" ground electrodes or module plates.

For example, in some embodiments, the module plate may be provided with communication holes at different positions to achieve different tortuous flows.

For example, in some embodiments, different communication holes can be provided, such as through communication holes at both the inflow and outflow ends of the cooling fluid, so that all intermediate module plates can be of the same construction (inflow and outflow holes can be juxtaposed or staggered settings).

For example, in some embodiments, the recesses on both side surfaces of the middle module board may have the same depth, and both side surfaces have accommodating grooves for accommodating the joint portion.
