The specific embodiment
As shown in Figure 1, device of the present invention is made of indoor-outdoor air suction selecting pipeline, air delivery pipe road, carbon dioxide transformation absorption pipeline, carbon dioxide and nitrogen adsorption pipeline and recirculation line parallel with one another, and above-mentioned each pipeline links to each other successively by pipeline.The air suction selecting pipeline is gone up constituting with the indoor tracheae 2 of going into of going into tracheae 1 and being communicated with outdoor air that links to each other of connecting by two-position three-way valve 3 and two inlet, air delivery pipe route mini air pump 4 and 3-position-3-way valve 5 constitute, the inlet of mini air pump 4 links to each other by the outlet of pipeline with two-position three-way valve 3, its two outlet links to each other with nitrogen and carbon dioxide adsorption chamber 8 with carbon dioxide adsorption chamber 10 by pipeline respectively, link to each other by the inlet of pipeline respectively on the inlet of carbon dioxide adsorption chamber 10 and nitrogen and carbon dioxide adsorption chamber 8 with two-position three-way valve 7, the outlet of two-position three-way valve 7 links to each other by the inlet of pipeline with vavuum pump 6, the outlet of vavuum pump 6 communicates with atmosphere by pipeline, recirculation line is by magnetic valve 11, magnetic valve 9 and feedback pipe 12 constitute, the entrance and exit of magnetic valve 11 links to each other with feedback pipe 12 by the outlet of pipeline and adsorption chamber 10 respectively, and the entrance and exit of magnetic valve 9 links to each other with feedback pipe 12 with the outlet of adsorption chamber 8 by pipeline respectively.
Gas concentration lwevel in the sensing chamber, when gas concentration lwevel surpasses 7%, need to get rid of indoor carbon dioxide, it is electric that two-position three-way valve 3 is got, and the right coil of 3-position-3-way valve 5 gets electric, magnetic valve 11, go into tracheae 1, two-position three-way valve 3, mini air pump 4 like this, 3-position-3-way valve 5, carbon dioxide adsorption chamber 10, magnetic valve 11 and feedback pipe 12 have constituted the circulation of air loop.What fill in the carbon dioxide adsorption chamber 10 is carbon dioxide absorber, and when air flow through this adsorbent, carbon dioxide was attracted on the adsorbent, and oxygen, nitrogen can be by in this adsorption chamber inflow room.When adsorption chamber is filled carbon dioxide, need carry out desorb to adsorbent, after the carbon dioxide that desorbs was excluded, adsorbent promptly can be used for adsorbing next time.When mini air pump 4 work, minipump 6 is not worked, when minipump 6 work, mini air pump 4 is not worked, when row's carbon dioxide, mini air pump 4 flows to carbon dioxide adsorption chamber 10 with the higher air of indoor carbonated concentration, after absorption, the air that carbonated concentration is lower is sent back to indoor, after work a period of time, be filled carbon dioxide in the carbon dioxide absorber, disconnected mini air pump 4,3-position-3-way valve 5 this moment, magnetic valve 11 gets electric, and two-position three-way valve 7 is got.So when minipump 6 gets electric work, in carbon dioxide adsorption chamber 10, produce vacuum, the carbon dioxide that is adsorbed in the carbon dioxide absorber is desorbed, and be discharged in the atmosphere by minipump 6, after carbon dioxide had been arranged, minipump 6 quit work, and made mini air pump 4,3-position-3-way valve 5, magnetic valve 11 once more electric, thereby carry out the another work of getting rid of indoor carbon dioxide of taking turns.
Detect indoor oxygen concentration and be lower than at 19% o'clock, two-position three-way valve 3 must not, and magnetic valve 9, the left coil of 3-position-3-way valve 5 gets, so go into tracheae 2, two-position three-way valve 3, mini air pump 4,3-position-3-way valve 5, nitrogen and carbon dioxide adsorption chamber 8, magnetic valve 9, feed back pipe 12 and form the oxygen supply loop, when the miniature air pump work, outdoor fresh air is through going into tracheae 2,3-position-3-way valve 5 etc., be fed to nitrogen and carbon dioxide adsorption chamber 8, be filled with nitrogen and carbon dioxide absorber at this adsorption chamber, carbon dioxide in air and nitrogen all are adsorbed, and that high-concentration oxygen is transported to is indoor.After adsorption chamber 8 is filled nitrogen and carbon dioxide, mini air pump 4,3-position-3-way valve 5, magnetic valve 9 is dead electricity all, for the desorb and the eliminating of nitrogen, carbon dioxide are got ready; After mini air pump 4 dead electricity, minipump 6, this moment, two-position three-way valve 7 must not, so in nitrogen and carbon dioxide adsorption chamber 8, form vacuum, nitrogen in this adsorption chamber 8 and carbon dioxide are discharged in the atmosphere by desorb and by minipump 6, after nitrogen and carbon dioxide have been arranged, minipump 6 quits work, and mini air pump 4, magnetic valve 9 and 3-position-3-way valve 5 are again, so to indoor supplemental oxygen, like this, oxygen supply---denitrogen gas---oxygen supply is worked again and again.
Certainly, device therefor of the present invention also can be made of the independent transformation absorption pipeline of two-way, promptly separately from indoor suction air, removes carbon dioxide by transformation, to reduce gas concentration lwevel; Establish one the road more separately from outdoor absorption air, remove carbon dioxide and nitrogen by transformation absorption, be input into indoorly again, this embodiment must belong to protection scope of the present invention.
