2) and water (H
2O), become harmless gas, simultaneously other harmful air pollutants are also had capacity of decomposition, for example: benzene (C
6H
6) through the oxidation of ozone, be decomposed into carbon dioxide (CO
2) and water (H
2O), ammonia (NH
3) through the oxidation of ozone, be decomposed into nitrogen (N
2) and water (H
2O), carbon monoxide (CO) is decomposed into carbon dioxide (CO through the oxidation of ozone
2) and water (H
2O), ozone not only can decompose poisonous and hazardous gas simultaneously, the ability that also has sterilization simultaneously, for example microorganisms such as bacterium, tubercle bacillus, fungi, mould gemma, virus all had extremely strong dissipation effect, and owing to the half-life of ozone is very short, many and ozone will be reduced to oxygen, so remove toxic and harmful in room air, importing a certain amount of ozone is effective way.
But, what all present ozone generators did not generally solve is the technical problem of uncontrollable ozone generating capacity, and excessive and concentrated exactly ozone can allow the people feel under the weather, ozone with high concentration even human body is come to harm, according to relevant regulations, the standard that indoor air contains ozone amount is at present: ozone (O
3) concentration in room air must not surpass 0.16mg/m
3Can control the ozone generating capacity so provide a kind of, meet the ozone generator of this standard, be the present technical issues that need to address.
The utility model content:
Technical problem to be solved in the utility model provides the ozone generating-device that a kind of full-automatic air purifies oxygenating.
The purpose that this full-automatic air that this case provides purifies oxygen supplementing device is this device character and content of the interior major pollutants of measuring cell automatically, and according to this information, an amount of ozone quantitatively takes place in good time, and airborne ozone content in the control room, make it to be in always and meet country's " IAQ standard ".
For solving the problems of the technologies described above, realize above-mentioned technical purpose, the technical scheme that the utility model adopted is:
The air cleaning unit of safe colleges and universities provided by the utility model, comprise a pernicious gas qualitative and quantitative detection sensor, a signal amplifier, an A/D converter, a Programmable Logic Controller, an ozone generating-device and an oxygen supplementing device, described harmful gas qualitative and quantitative detection sensor, a signal amplifier, an A/D converter, a Programmable Logic Controller, one ozone generating-device transmits in order mutually, the on off state of described Controlled by Programmable Controller ozone generating-device and described oxygen supplementing device.
Described pernicious gas qualitative and quantitative detection sensor is one or more combination in ampere-type formaldehyde (HCHO), benzene (C6H6), ammonia (NH3), carbon monoxide (CO) electrochemical sensor.
Described ozone generating-device is that a metal tungsten powder is sintered to the element on the ceramic substrate, constitutes two groups of tungsten grizzly bars of isolating mutually on the substrate and produce electric spark under the excitation of high voltage source, and airborne oxygen conversion is become ozone.
Described oxygen supplementing device is that a switch is the oxygen cylinder of electromagnetic valve switch, and this magnetic valve is accepted the control of described Programmable Logic Controller.
Description of drawings:
The principle assumption diagram of the full-automatic air purifier that Fig. 1 provides for the utility model;
The specific embodiment:
The oxygen supplementing device of air cleaning safely and efficiently provided by the utility model, an ampere-type electrochemistry formaldehyde sensor 1 among Fig. 1, this formaldehyde sensor is the interior airborne content of formaldehyde of measuring cell accurately, a preamplifier 10 that constitutes by operational amplifier, the electrical signal transfer of output 4-20 milliampere is to the CH1 mouth of A/D converter 5, be input to A/D converter after the analog signal that the probe 1 of formaldehyde sensor is collected is amplified by preamplifier 10 and convert data signal to, be delivered to the microprocessor 6 of Programmable Logic Controller, calculate, when the content of formaldehyde surpasses national indoor 0.16mg/m
3The time, microprocessor 6 starts the work order that powers up to high pressure generator 8 at once, encourages pairing ozone generator 11 respectively, produces ozone.This ozone generator 11 be one on sintering on the ceramic substrate element of metal tungsten powder grizzly bar, constitute two groups of tungsten grizzly bars of isolating mutually on this ceramic substrate and under the excitation of high voltage source, produce electric spark, airborne oxygen is converted into ozone.The common generation of ozone generator is 100ng/h at present, 200ng/h, 400ng/h, 800ng/h, 1600ng/h, series such as 3200ng/h, this device also adopts the ozone generator of above-mentioned specification, but, by Programmable Logic Controller the ozone generator of above-mentioned specification is not originally controlled, by continuous sampling analysis to formaldehyde in indoor air and ozone amount, monitor in good time, instruct the duty of different ozone generators, just can obtain step value is 100ng/h, the output total amount is 16 kinds of ozone output quantities of 100-1500ng/h, regulate the time and the generation of ozone generating simultaneously, just can be in time quantitative airborne formaldehyde in the decontamination chamber effectively.
