Fig. 6 is DBD modules airflow series connection application example (dotted arrow represents airflow direction) of the Modular plate-type ozone generator according to the present invention, Fig. 7 is DBD modules airflow parallel connection application example (dotted arrow represents airflow direction) of the Modular plate-type ozone generator according to the present invention, Fig. 8 is that the DBD mould air-flow mixing of the Modular plate-type ozone generator according to the present invention couples application example (dotted arrow represents airflow direction), as shown in figs 6-8, the Modular plate-type ozone generator of the present invention is made up of top board 1 and N number of DBD module.Wherein, quantity N of DBD module arbitrarily can be selected by the needs of user and application, thus constitutes different scales, and different connecting modes, for the DBD ozonator of different application.
Air-flow series connection application mode: module group is made up of top board and N (N >=2) individual DBD module, upper gas passage 11 and the lower gas passage 13 of closure DBD module 22 can realize air-flow series connection application mode.As shown in Figure 6, oxygen-enriched stream enters first DBD module 22 DBD module group from top board 1 gas access 3, because the upper gas passage 11 of this DBD module is blocked, all air-flow is forced through electric discharge air chamber 21 region of this DBD module, finally after the lower gas passage 13 of this module converges, enter adjacent next DBD module 22, same, because the lower gas passage 13 of this module is blocked, all air-flow is forced through the electric discharge air chamber 21 of this DBD module, finally after the upper gas passage 11 of this module converges, enter next adjacent DBD module.The rest may be inferred, and final all air-flows are from the upper gas passage 11(even number DBD module composition module group of last DBD module 22) or lower gas passage 13(odd number DBD module composition module group) be discharged.
Air-flow parallel connection application mode: module group is made up of top board 1 and N (N >=2) individual DBD module 22, the upper gas passage 11 of the DBD module 22 of only closure distance top board distalmost end can realize air-flow parallel connection application mode.As shown in Figure 7, oxygen-enriched stream enters DBD module group from ceiling gas entrance 3, because in addition to the upper gas passage 11 of last DBD module 22 is blocked, the upper gas passage 11 of middle all of DBD module 22 all interconnects and is connected with the left air chamber 19 within each DBD module 22.Air-flow is averaged the electric discharge air chamber 21 being distributed to each DBD module, it flow to the right air chamber 20 of respective modules afterwards, the lower gas passage 13 of each DBD module 22 through being interconnected pools together, and finally the lower gas passage through last DBD module 22 is discharged.
Air-flow mixing couples application mode: module group is made up of top board 1 and N (N >=3) individual DBD module 22, which can be to regard the conjunctive use mode of above-mentioned series and parallel as, have only to block the upper gas passage 11 of middle DBD module 22, and the lower gas passage 13 of the DBD module 22 of distance top board distalmost end.As shown in Figure 8, oxygen-enriched stream enters DBD module group from ceiling gas entrance 3, until the DBD module that upper gas passage 11 is blocked, because upper gas passage 11 and the lower gas passage 13 of all DBD modules all do not block, so the application mode that corresponding DBD module 22 is air-flow parallel connection, because the upper gas passage 11 of middle DBD module is blocked, all air-flows all lower gas passage 13 through this DBD module must enter the latter half of module group, the DBD module 22 of this part is owing to only having blocked the upper gas passage 11 of DBD module DBD of distance top board distalmost end, other gas passages connect mutually, so again constituting the application mode that air-flow is in parallel.Air-flow finally collects at the upper gas passage 11 of the DBD module 22 of distance top board distalmost end and is discharged.I.e. it is the application that gas is in parallel inside the first half of module group and later half DBD submodule group, meanwhile, generally air-flow series relationship between forward and backward half module group.
The operation principle of the Modular plate-type ozone generator of the present invention and work process:
DBD module in ozonator of the present invention have employed and minimizes design, the inner space integration packaging narrow and small: high-field electrode assembly, the ground electrode with block media layer, electric discharge air chamber, gas passage, cooling passage and external air-liquid, electrical interface.External power source draws the connection rod of metal alloy of fitting 8 by power supply, alloy brush 16 is connected to electrode plate with high voltage 15, it is provided that the high frequency/high voltage power supply needed for work；Electrode plate with high voltage 15, electric discharge air chamber 21 and block media layer 17 collectively form required low temperature plasma environment.The oxygen rich gas come by source of oxygen is by gas access 3, upper gas passage 11, left air chamber 19, and discharge air chamber 21, synthesizes ozone in low temperature plasma atmosphere, and then by right air chamber 20, lower gas passage 13, gas outlet 4 derive.In actual applications, can be by the upper gas passage 11 of the corresponding ground electrode 18 with block media layer of closure respectively or lower gas passage 13, and and change the position of end DBD module group gas outlet 4 accordingly, the series, parallel between multimode or connection in series-parallel working method can be realized, and without increasing any peripheral components.
DBD module of the present invention in inner space, the runner distribution of reasonable distribution gas, liquid；Working gas and coolant reverse flow, thus obtain optimal heat exchange efficiency, and optimal operating temperature.In addition, air-liquid interface with the ground electrode 18 of block media layer: upper gas passage 11, lower upper gas passage 13, upper cooling passage 9, lower cooling passage 10, can directly connect with the ground electrode 18 of block media layer or the corresponding interface of top board 1 with adjacent.This built-in, compact structure design, enormously simplify the difficulty that multiple basic component is assembled, and greatly reduces the connection pipeline of outside.
