The air cleaning unit 2 is arranged at outside room 1, including solar concentrator 27;
The gas concentration lwevel sensor 7 is arranged in room 1, for detection gas concentration lwevel and is transmitted to described
Automaton 8;
The two-way blower fan 6 is arranged at outside room 1, circulation line 3 is connected on the two-way blower fan 6, for will be in room 1
Air be discharged to room 1 it is outer and will be outside room 1 the air by purification be sent into room 1;
Gas concentration lwevel in the room 1 that the automaton 8 is detected based on the gas concentration lwevel sensor 7
To control the operation of the two-way blower fan 6;
The circulation line 3 is internally provided with alkaline-earth metal oxygen the pipeline section 25 corresponding to the solar concentrator 27
Compound adsorbent 23, the solar concentrator 27 heats alkaline earth oxide adsorbent 23, with to two-way blower fan 6
Air in the room 1 of extraction is purified.It is also set up in pipeline section 25 there are two silica wool 22, alkaline earth oxide adsorbs
Agent 23 is between the two silica wools.Pipeline section 25 and the other parts of circulation line 3 are detachably connected, and are so convenient in it
23 grade attachmentes of portion's installation alkaline earth oxide adsorbent.
Further, regenerative apparatus 4 is additionally provided on the circulation line 3, for the room 1 that two-way blower fan 6 is allowed to extract out
It interior air and exchanges heat through the purified air of alkaline earth oxide adsorbent.
Further, the regenerative apparatus 4 is radiating fin.
Further, there are two the solar concentrator 27 is set, correspondingly, circulation line 3 is corresponding to each described
The inside of the pipeline section 25 of solar concentrator 27 is respectively arranged with alkaline earth oxide adsorbent 23, and the two described pipes
The head and the tail of section 25 are both connected to together, and junction is respectively arranged with three-way magnetic valve 9, pass through three-way magnetic valve 9 and Xun Huan
Other pipeline sections connection of pipeline, for flowing of the switching air in the two pipeline sections 25, the opening and closing of the three-way magnetic valve 9
It is realized by the automaton 8.

Below in conjunction in the classroom of 50 ㎡, the CO of 20 people is purified2The actual purification feelings to the present invention of discharge capacity
Condition illustrates.
The generation total amount of carbon dioxide is 0.346m in said case3/ h is computed CaO adsorbents to the CO in return air2
Removal rate can reach more than 90%.By pollutant equilibrium equation in room 1, after calcium oxide adsorptive purifier is added,
Required fresh air volume is reduced to 13m3/ h, return air amount are reduced to 30m3/ h, temperature is 450 DEG C after air preheat, 650 DEG C of reaction temperature,
Because decomposing during regeneration, reaction is set as V=3m without higher gas flow rate air inlets3/h.It is calculated at the sun
The power of auxiliary electrical heater needed for regeneration temperature can be reached after optically focused heating for 203.5W, alkaline earth oxide adsorbent is main
Ingredient is CaO.1g CaO adsorbents can absorb 0.3g CO after repeatedly cycling at reaction conditions2(see Fig. 5).Pipe internal oxidition calcium
Adsorbent is sphere (3-5mm), and oxidation calcospherite bulk density is 411.92kg/m3.Further, the alkaline-earth metal
Oxide adsorbent absorption bore is 64mm, length 3m.The CaO adsorbent mass of filling is 3.9kg in sleeve.It is theoretical
On can adsorb 1.17kg carbon dioxide per hour, be converted into 0.6m3.It is computed, is carried out when the alternate cycles 1.5 of two set of tubes are small
Once.
The system is chemical so as to utilize for exothermic reaction using the reaction of alkaline earth oxide adsorbent and carbon dioxide
Heat and gas regenerative apparatus 4 are energy saving to the greatest extent using gas reaction preheating, the also guarantees such as solar energy.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, not to
