Head, hydrogen peroxide probe are distributed in the surge chamber two sides；The gas outlet of the check-valves setting and the surge chamber.
Preferably, the flow velocity of the air pump is adjustable.
Plasma disinfecting-sterilizing method under a kind of room temperature, includes the following steps:
S100: the plasma for being rich in active particle is generated, mixes with air to form plasma (orifice) gas；
S200: plasma (orifice) gas is buffered at the uniform velocity discharge arrival receptor and is chemically reacted.
Compared with prior art, disclosure bring has the beneficial effect that
1, the disclosure can produce the active material of higher concentration without adding other bactericidal agents；
2, the disclosure can generate plasma at normal temperature, be not necessarily to vacuum negative pressure device, and equipment is simple, easy to operate,
Reduce manufacturing cost；
3, the disclosure can produce various active particle and density is high, and sterilizing speed is fast, high-efficient；
4, the disclosure is simply portable, can be applied to a variety of different occasions and carries out disinfection sterilizing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of plasma sterilization device under a kind of room temperature shown in the disclosure.
Specific embodiment
The technical solution of the disclosure is described in detail with reference to the accompanying drawings and examples.
Referring to Fig. 1, plasma sterilization device under a kind of room temperature, comprising: module 100, surge chamber occur for plasma
200, air pump 300 and gas conduit 400；The plasma occurs module 100 and is used to generate the plasma rich in active material
Gas；The air pump 300 is connected with the surge chamber 200, and plasma (orifice) gas is sent into the surge chamber 200；The surge chamber 200
Module 100 occurs with the plasma by the gas conduit 400 to be connected, so that being at the uniform velocity discharged after plasma (orifice) gas buffering.
Above-described embodiment constitutes the complete technical solution of the disclosure.Mould occurs for the plasma in disclosure described device
The high concentration active particle that block 100 generates can be diffused into the air of device circulation and form plasma (orifice) gas.It will be produced by air pump 300
Raw plasma (orifice) gas is sent into surge chamber 200 and is buffered, be discharged flow speed stability, for sterilizing plasma (orifice) gas used, have very
Good sterilization effect.
In another embodiment, it includes high voltage power supply and discharge electrode that module 100, which occurs, for the plasma.
In the present embodiment, high voltage power supply regulating discharging voltage, frequency and discharge time further can be in high-voltage electricity
It installs pulse-modulator on source additional and adjusts power supply wave shape.Under the excitation of high voltage power supply, discharge electrode electric discharge generates plasma.
In another embodiment, dielectric barrier discharge structure, needle-cylinder discharging structure is can be selected, along face in the discharge electrode
Any one under discharging structure or other atmospheric pressure in plasma discharge configuration.
In another embodiment, the surge chamber 200 includes ozone concentration probe 201, hydrogen peroxide probe 202 and non-return
Valve 203；The ozone concentration probe 201, hydrogen peroxide probe 202 are distributed in 200 two sides of surge chamber；The check-valves
203 are set to the gas outlet of the surge chamber 200.
In the present embodiment, ozone concentration probe 201, hydrogen peroxide probe 202 are for detecting ozone and content of hydrogen peroxide
Whether sterilizing standard is reached and whether more than national emission standard.It is unstable into the plasma (orifice) gas meeting flow velocity in surge chamber 200,
Check-valves 203 ensures that gas outlet is opened when the air pressure in surge chamber 200 reaches certain value, so that flow of exhaust speed tends to one surely
Definite value, and prevent outside air from entering device.
In another embodiment, the flow velocity of the air pump 300 is adjustable.
