Description of the drawings
Fig. 1 is the schematic diagram of polluted gas purifier according to an embodiment of the invention.
Specific embodiment
The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings it is described in detail polluted gas purifier according to embodiments of the present invention.
As shown in Figure 1, polluted gas purifier according to embodiments of the present invention, including：Reaction chamber 100, water tank 200,
Atomizer 300.
Specifically, reaction chamber 100 is equipped with import 101 and outlet 102.Advantageously, import 101 is located at reaction chamber 100
Top, the bottoms that outlet 102 is located at reaction chamber 100.
There is the water-mist outlet 201 connected with reaction chamber 100 on water tank 200.
The atomizer 300 of such as ultrasonic atomizer is located in water tank 100.
Atomizer 300 for being atomized to generate water mist to the water in water tank 100, water mist by water-mist outlet 201 into
Enter into reaction chamber 100.At the same time, it pollutes the polluted gas such as air, flue gas, kitchen fume and is introduced into reaction chamber
It is interior (that is, import 101 can with it is indoor connect or outlet with the outlet of flue or with smoke exhaust ventilator), water
Mist is come into full contact with polluted gas in reaction chamber.
It is as follows to the purification mechanism of polluted gas：
For fine particles such as the dust in polluted gas, the nuclei of condensation can be used as, water mist are made to form water droplet, to detach dirt
Contaminate the fine particles such as the dust in gas；For carbon dioxide, sulfur dioxide, nitrogen dioxide, hydrogen sulfide, the chlorine in polluted gas
The pernicious gases such as gas can form aqueous solution fine droplets together with water mist, together with above-mentioned water droplet, be detached from polluted gas,
So as to achieve the purpose that purifying contaminated gas.Water containing fine particle and pernicious gas and purified air can together from
201 discharge of outlet, collects these waste water and does further harmless treatment, and purified air can be then discharged in air.
An example according to the present invention, the polluted gas purifier further include cathode electrode 401 and anode electrode
402.The cathode electrode 401 and anode electrode 402 for being such as configured to comb teeth-shaped are each provided in water tank 100.
For being electrolysed to the water in water tank 100 to generate hydrogen, anode electrode 402 is used for water cathode electrode 401
Water in case 100 is electrolysed to generate oxygen.Water mist is squeezed by the volume expansion of hydrogen and oxygen so that water mist
It is entered in reaction chamber 100 by water-mist outlet 201.
What needs to be explained here is that in the status of criterion (STP) 0 DEG C of (273K), 1.01 × 105Under Pa, 1 mole of any ideal
Volume shared by gas may each be about 22.4 liters, this volume is called the molar volume of gas, and unit is L/mol (rises/mole), i.e.,
(STP) molar volume of gas is 22.4L/mol under the status of criterion.At 25 DEG C, 1.01 × 105The volume of gas molar is about during Pa
24.5L/mol。
It is known that electrolysis 2mol water (volume about 36mL), can obtain 2mol hydrogen and 1mol oxygen (the two
Volume about 75L), volume increases more than 2000 times, and the volume of water tank is then constant.So, in order to seek air pressure balance, this
It is electrolysed obtained hydrogen a bit and the water mist that atomizer 300 is atomized can be pushed to from water-mist outlet 201 in reaction chamber by oxygen, effectively
Solves the conveying dynamical problem that water mist enters in reaction chamber 100.Also, hydrogen and oxygen will not all cause air secondary dirt
Dye.
An example according to the present invention, the polluted gas purifier further include getter device 500.Getter device
500 are connected with reaction chamber 100.The getter device 500 of such as suction fan or asepwirator pump is used to inhale polluted gas by import 101
Enter in reaction chamber 100.Advantageously, getter device 500 can be located in import 101.
An example according to the present invention, the polluted gas purifier further include liquid level gauge 600.Liquid level gauge 600 with
Water tank 100 is connected.Liquid level gauge 600 can be linker liquid level gauge or liquid level sensor, can understand user's moment
Water level in water tank 100 avoids water tank lacks water or to moisturizing excessive in water tank.
The course of work of polluted gas purifier according to embodiments of the present invention is as follows：
The polluted gas of indoor pollution air, flue gas, kitchen fume etc., by 500 sucting reaction of getter device
In case 100.
At the same time, atomizer 300 is atomized the water in water tank 200, to generate subtle water mist, cathode electrode 401
The water in water tank 200 is electrolysed with anode electrode 402, to generate hydrogen and oxygen.
These hydrogen and oxygen are pushed water mist into reaction chamber 100 by volume expansion, be water mist in reaction chamber 100 with
Polluted gas comes into full contact with to form water droplet, detaches fine particle and pernicious gas in polluted gas, purifies air.
These water droplets and purified air are further done harmless together from 202 discharge of outlet after being collected to water droplet
Change is handled, and purified air can be discharged into air.
The advantageous effect of polluted gas purifier according to embodiments of the present invention is：
1st, it is carried out at the same time by ultrasound and ionization and obtains gas and mist particulate of different sizes；
2nd, different from filter method, pass through gas and mist particulate capture dust of different sizes；
3rd, method different from the past generates carbonic acid polymer fume using mist water and carbon dioxide reaction；
4th, the liquid of liquid nitrogen and electricity usage amount polymerization simultaneously can be controlled to collect through liquid nitrogen cooling by reaction chamber, declined
Improve efficiency；
5th, Collection utilization after the dehydrations such as tobacco tar, carbonated water formed；
6th, using above method novelty solution comprehensively, thoroughly, safe handling haze.
