It is arranged with "-" type.
Those skilled in the art can according to above-mentioned technical concept, expect naturally using more than four fixed rod structures into
Row layout designs, applicant are no longer directed to four, six, eight, 12 etc. fixed link quantity and carry out citing description one by one.
When using more than two fixed links 13, the discharge tip 12 of the electrode slice 11 in two neighboring fixed link 13 it
Between keep at a distance, so that whole discharge tips 12 is evenly distributed on the section of the airflow channel 15.This distance is also according to voltage
Height preset, under the premise of ensuring all air gaps all in point discharge region, voltage is higher, this distance can be with
What is be arranged is bigger.
Adjacent three fixed links 13 are triangularly arranged, and the electrode slice in three fixed links is in interlaced arrangement two-by-two,
The interlaced arrangement of electrode slice can make the density of the discharge tip on electrode slice bigger, and the airflow channel for covering electrode slice
Area it is also bigger, keep air molecule also just bigger by the probability of the ionization of point discharge, to greatly improve plasma
The yield of body improves the working efficiency of high voltage direct current plasma generator.
Selectively, as shown in Figure 1, setting metallic conduction structure for fixed link, conductive sheet is directly anchored to fix
On bar, connects and be connected by the cathode of fixed link and high-voltage DC power supply.
Alternatively, selectively, sleeve 14 is provided between the two neighboring electrode slice in the same fixed link, to limit
The distance between two neighboring electrode slice, at this point, by sleeve 14, fixed link 13 at least one of be set as metallic conduction knot
Structure.
Electrode slice in different fixed links can be identical with size, can also be of different sizes；And the electric discharge of electrode slice 11
The quantity at tip 12 can also be identical or different.For example, can be arranged in three fixed links of distribution triangular in shape biggish
Electrode slice is arranged a fixed link at three fixed link centers again, lesser electrode slice is arranged in the fixed link.
The wall of the airflow channel is manufactured using insulating materials, and the shape of the airflow channel and its internal electrode
The construction of piece is adapted.

Generator 10, reaction chamber 20, resolution room 30, blower (not shown) and high-voltage DC power supply (not shown), the height
The outlet side of straightening stream plasma generator 10 is connected to the reaction chamber 20, and the reaction chamber 20 connects with the resolution room 30
Logical, the resolution is indoor to be provided with the porous resolution structure (not shown) that can clear up ozone, the high voltage direct current
The cathode in source is connected with the electrode slice of the high voltage direct current plasma generator, and the blower passes through the height for certain driving air-flow
Straightening stream plasma generator.Air is first under blower bring suction function, into high voltage direct current plasma generator 10,
Point discharge is generated when high voltage direct current plasma generator 10 works, ionized air forms plasma, then into anti-
It answers in chamber 20, purified treatment is carried out to gas, remaining plasma is passing through the discharge of resolution room in the gas after handling
In the process, the resolution structure for being resolved chamber interior is cleared up.
The blower is arranged in the reaction chamber, the inlet end of the high voltage direct current plasma generator or described disappears
Solve room outlet side.
The high voltage direct current plasma generator is equipped with multiple and is arranged side by side, and in high voltage direct current plasma generator
Between gap with sealing plate (not shown) block.For example, when the airflow channel of high voltage direct current plasma generator is circle
When, being arranged side by side between multiple airflow channels will form gap, this gap sealing plate blocks, avoid fraction without
It crosses high voltage direct current plasma generator and enters directly into reaction chamber 20.
The high voltage direct current plasma generator, reaction chamber, resolution room are linearly arranged, on the one hand use linear arrangement can
To save space, keep topology layout more reasonable, reduce volume, on the other hand can also guarantee that air-flow is unimpeded using linear arrangement,
It reduces air-flow and turns to bring resistance.
Ozone sensor is provided in the reaction chamber, the ozone sensor is connect with control module, the control
Module is used to control the high voltage direct current plasma generator according to the signal for receiving ozone sensor and the blower successively stops
Machine.Using first shut down high voltage direct current plasma generator, after shut down blower by the way of, can be to avoid the ozone plasma of generation
It is advanced in atmosphere no by resolution, to guarantee its safety.In actual application, timing can also be used
