The pulse streamer discharge ozone generator has the technical effects that 1, energy which is converted into ions and neutral substances is reduced, an exquisite cooling system is not required to cool an electrode, and the cost is saved; 2, high-energy electrons are generated, the generation of low-energy electrons is reduced, and the output and the concentration of ozone are improved; and 3, a discharge gap of the discharge plate and the thickness of a dielectric medium can be regulated.
Description
Technical field
The utility model is a kind of ozonizer, relates in particular to a kind of stream of pulses light discharge ozonizer.
Background technology
Ozone is the allotropic substance of oxygen molecule, under the normal temperature is to be light blue, to be with careless fishy smell gas.Density under the standard state is 2.144 kg/m3.The solubleness of ozone in water approximately is 10～15 times of oxygen, but less stable.Ozone is widely used in departments such as oil, chemical industry, weaving, food, pharmacy and spices as a kind of strong oxidizer, sterilizing agent, finishing agent, catalyzer etc.Because ozone has extremely strong oxidation capacity, therefore it has extremely strong sterilization operation, decolouring, deodorization, takes off flavor effect and Decomposition, it is widely used in aspects such as drinking water disinfection, sewage disposal, medicine equipment and tableware sterilization, food sterilization are fresh-keeping, medical treatment, and it does not produce secondary pollution when oxidize contaminants, therefore people call it " the strong oxidation medicament of the omnipotent green of ideal " usually, and it replaces chlorine to become a kind of trend.
At present, commercial ozonizer mainly is to utilize dielectric barrier discharge, power supply generally adopts high frequency and high voltage power supply, ozone concn and productive rate be about 16.55 ~ 60.7 g/m3 respectively and less than 111 g/kWh(source of oxygen), the ozone productive rate is far below theoretical value 1226g/kWh.In recent years, for improving ozone generation efficiency, relevant above-mentioned research work has had very big progress, raising ozone productive rate and concentration that these technology can only be limited although many scholars are to ozonizer.Therefore, seek a kind of new technology and just seem particularly urgent to improve ozone productive rate and concentration significantly.
Summary of the invention
The purpose of this utility model is to provide a kind of stream of pulses light discharge ozonizer, and this ozonizer can reduce the ozone generation energy consumption greatly, does not need exquisite cooling system cooling electrode, and discharging gap and dielectric thickness can be regulated as required.
The utility model is achieved like this, it comprises the pulse power, discharge electrode, under meter, it is characterized in that the high-voltage output end of the pulse power connects the nickel platinized platinum of discharge electrode, the ground terminal of the pulse power connects the stainless steel plate of discharge electrode, the air inlet port connection traffic meter of discharge electrode.
The described pulse power is the high-voltage pulse power source of nanosecond pulsewidth.
Described discharge electrode comprises nickel platinized platinum, ceramic plate, sheet rubber, stainless steel plate, the ceramic plate two ends are pressed with sheet rubber, the front of ceramic plate is pressed with the nickel platinized platinum, the ceramic plate back side connects stainless steel plate by sheet rubber and forms air flue, leave air inlet port and production well between the stainless steel plate, air inlet port and production well communicate with air flue, and nickel platinized platinum upper strata is connected with stainless steel plate.
Technique effect of the present utility model is: the energy that 1, changes into ion and neutral substance reduces, and does not need exquisite cooling system cooling electrode, saves cost; 2, produce high-energy electron, reduced the generation of low-energy electron (2～8.4 eV), increased the output and the concentration of ozone; 3, discharge electrode discharging gap and dielectric thickness can be regulated.

Embodiment
As shown in Figure 1, the utility model is achieved like this, it comprises the pulse power 1, discharge electrode 2, under meter 3, it is characterized in that the high-voltage output end of the pulse power 1 connects the nickel platinized platinum of discharge electrode 2, the ground terminal of the pulse power 1 connects the stainless steel plate of discharge electrode 2, the air inlet port connection traffic meter 3 of discharge electrode 2.
The described pulse power 1 is the high-voltage pulse power source of nanosecond pulsewidth.
As shown in Figure 2, described discharge electrode 2 comprises nickel platinized platinum 4, ceramic plate 5, sheet rubber 6, stainless steel plate 7, ceramic plate 5 two ends are pressed with sheet rubber 6, the front of ceramic plate 5 is pressed with nickel platinized platinum 4, ceramic plate 5 back sides connect stainless steel plate 7 by sheet rubber 6 and form air flue, leave air inlet port and production well between the stainless steel plate 7, air inlet port and production well communicate with air flue, and nickel platinized platinum upper strata is connected with stainless steel plate.
This device is by utilizing the high-voltage pulse power source of nanosecond pulsewidth, pulse energy is compressed on time scale, obtained in utmost point high-peak power output of (nanosecond) in the short period of time, reduced the generation of low-energy electron (2～8.4 eV), thereby make that the decomposition of ozone is slow, increased the productive rate and the concentration of ozone.At present, commercial ozonizer mainly is to utilize dielectric barrier discharge, power supply generally adopts high frequency and high voltage power supply, ozone concn and productive rate be about 16.55 ~ 60.7 g/m3 respectively and less than 111 g/kWh(source of oxygen), and the employing pulsed high voltage generator, ozone concn and productive rate best result are not 57.9 g/m3 and 581.09 g/kWh(source of oxygen), therefore greatly reduce energy consumption, saved cost.
