Description
Technical field
A kind of ozone generating-device is the utility model is related to, it is particularly a kind of without calibration, stable and reliable for performance, structure knot
It is real, and can be i.e. with ozone generating-device i.e..
Background technology
Ozone is widely used in the field such as water process, portable Flow Velocity Meter, smell control and food production.In these necks
Domain will be applied to substantial amounts of ozone gas on-line detector, therefore the demarcation to these live on-line computing model sensors seems
It is particularly important.
Ozone is that pollutants in air chemistry poisons the main participant developed and urges power, is prediction pollutants in air
The main monitoring object of harm.Due to ozone physics in itself and chemical property so that the preparation of ozone standard gas can not adopt
Prepared, stored, transported with the preparation method of traditional gas standard substance.Prepare ozone standard gas and must use and " match somebody with somebody
Use " method, this adds increased ozone standard gas prepare and storage difficulty.Ozone has strong oxidizing property and chemistry in itself
Activity is both strong oxidizer and powerful catalyst.Have in fields such as industrial ageing test, sewage disposal and medical and health sterilizations
It is widely applied.The ozone of adjacent ground surface is a kind of important dusty gas simultaneously, and research in recent years finds that mankind's activity is made
Into atmosphere pollution, not only increase considerably urban area adjacent ground surface ozone concentration, and surface ozone concentration has generally
Increased trend, surface ozone concentration increase is very harmful.All these demands are required for entering using ozone analyzer
Row measurement quantization, because the ozone standard gas of ozone analyzer calibrating must be " i.e. with i.e. use ", therefore ozone standard fills
The demand put is growing.Therefore, we have developed a kind of without calibrating, stable and reliable for performance, rugged construction, and can be i.e. with i.e.
Ozone generating-device.
Utility model content
The purpose of the utility model is to provide one kind without calibration for overcome the deficiencies in the prior art, and stable performance can
Lean on, rugged construction, and can be i.e. with ozone generating-device i.e..
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of ozone generating-device, including hair are provided
Generating apparatus and detection means；The generating means include device for drying and filtering, pressure-reducing valve, mass flow controller, ozone generator,
First triple valve, the second triple valve and controller；During work, compressed air first passes through device for drying and filtering and goes to remove water as source of the gas
Point and impurity, then after pressure-reducing valve is depressurized, pass through mass flow controller accurate flow control so that occur into ozone
The gas flow of device is accurately controlled in setting value；Gas enters ozone generator after mass flow controller；Ozone is sent out
The ozone gas of raw device generation is by the way that ozone gas enters detection means progress gas concentration detection all the way after the first triple valve, separately
Calibrated all the way by the second triple valve output ozone gas for Other Instruments outside；The data that the detection means measures pass through string
The controller of mouth and generating means is communicated, and controller adjusts the size of current of low pressure mercury lamp so as to reality by PID regulator
The control of existing ozone concentration occurrence value.
Preferably, the ozone generator uses low pressure mercury lamp as light source, launches the ultraviolet light of a wavelength range,
The sub- absorbing wavelength of ambient oxygen partial is 185nm ultraviolet photogenerated ozone molecule, so as to generate ozone gas.
Preferably, the shell of the ozone generating-device is made of stainless steel.
Preferably, the setting value is 5L.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
Ozone generating-device described in the utility model is simple in construction, is easy to adjust and dismounts, easy to control directly perceived；Simultaneously
Routine use is stable and reliable for performance without calibration；The shell of ozone generating-device described in the utility model uses stainless steel
Matter is made, durable.
