Description
Technical field
The utility model relates to ozone generating-device, relates in particular to a kind of dielectric barrier discharge ozone generating-device.
Background technology
For ozonizer, anion generator, in plasma treatment and other discharge process core component working process, can produce a large amount of heats, this heat output must be lost with guarantee equipment and works at a lower temperature, dielectric barrier discharge ozone generating-device core component is between electrode, to have one deck dielectric substance, dielectric substance is between interior electrode and outer electrode, between dielectric substance and an electrode, be provided with gap as fluid channel, in the time mating suitable driving power between interior electrode and outer electrode, controlled discharge obtains needed different discharge effect, thereby obtain and output ozone gas mixture or plasma gas mixture with later use.Discharge process is accompanied by obvious exothermic effect, if can not fine design heat-dissipating structure and technique, to make electrode and dielectric substance temperature improve constantly or remain on very high-temperature, and make discharging fluid can not be converted into efficiently and stably desired substance, serious dielectric substance and the electrode of even puncturing.
Optimal situation is under lower temperature range and relative temperature constant state, to work by guarantee equipment.Prior art adopts according to distinct device structure is general that simple single electrode is air-cooled or two electrodes is air-cooled, or the air-cooled interior electrode water-cooling pattern of outer electrode, and such type of cooling exists a lot of problems, and does not reach technical requirements.When for ozonizer, air-cooledly electrode and medium can not be controlled at temperature to desirable low-temperature condition in a long time, ozone productive rate is very low at all, and concentration is also very low, thereby cause whole set equipment only can be used in lower concentration space disinfection industry the short period of time, and unit power consumption is very large.Reasonable scheme is to adopt outer electrode list water-cooled, more better scheme adopts the air-cooled electrode water-cooled of an electrode, water coolant adopts disposable in line or recycle system secondary heat radiation, but still there are two problems in water-cooled, because adopt tap water and make system gradually fouling make cooling system lost efficacy, need to use pure water or other safer heat-conducting fluid and increase cost of investment, in any case, all heat up and heat delivery arrived outside by heat-conducting fluid contact heating electrode, between heating electrode and fluid, always maintain a higher thermograde, fluid is by general secondary heat radiation behind the electrode thermal output outside vaporizer wind method of cooling that adopts, therefore heat-conducting fluid temperature also can keep a higher gradient relative to outside temperature, the existence of secondary thermograde makes electrode temperature far above outside temperature, electrode can only keep comparatively high temps working order, its working effect is unsatisfactory, unless the freezing heat exchange mode of the cooling employing of secondary, and such method is from investment, the angle of taking up an area and move is difficult to accept, particularly middle-size and small-size equipment, too complicated system penetration and promotion in practice in addition.Nonetheless, if want keeping system working temperature a desirable low temperature range job, automatically control extremely difficult realization, these all become the bottleneck of correlation technique progress.
Common dielectric barrier discharge ozone generating-device is as tubular discharge device, and outer tubular electrode is easy to by fin-shaped scatterer, its heat loss be arrived extraneous, and interior electrode can not simply solve by similar approach.As shown in Figure 1, conventional method is by internal electrode structure water stream channel, utilizes normal temperature flowing water to take away heat, and this structure is wasted a large amount of water coolants, is difficult to the four seasons effective at northern area, is particularly difficult to automatically keep cooling of electrode temperature range.As shown in Figure 2, carry out secondary heat radiation to interior electrode peripheral hardware circulating cooling system, this system complex and taking up space, often cause dispelling the heat bad because adopt cooling water evaporation to supplement deficiency, or lost efficacy down to blocking because water quality fouling is serious, or because the system component faults such as water circulating pump cause inefficacy, even if adopting, system radiating medium still can not thoroughly address these problems such as special cooling fluid or cooling oil.Another method as shown in Figure 3, to be designed to enclosed construction with interior electrode contact refrigerant, by interchanger and secondary degree of depth cooling system exchange heat radiation, this structure is more complicated, cost is higher, takes up an area greatlyr, and working cost is higher, trouble spot is more, is only applicable to be suitable for without other Large-Scale Equipment of selection scheme.
With the exception of this, existing structure cannot by load device with mate power standard, thereby be also not suitable for any assembly standardised prod to enhance productivity and to obtain accurate production capacity equipment, as shown in Figure 4, thereby different power supplys makes between each electric discharge device altogether by sharing a set of interior electrode heat-removal system, the difficulty that has increased insulation difficulty and electromagnetic shielding, makes complete machine in fragile state.
