Background technique
Usually when carrying out some animal gases concentration model experiments, can using animal raising box come isolation experiment animal with
External environment, and by oxygen concentration control come carry out animal gas model test.Since this kind of rearing-box is usually opposite
Closed, gas exchange capacity is very low, is unable to fully the CO2 gas that discharge animal metabolism generates.This gas can be accumulated constantly, dense
Degree is lasting to be increased, and is influenced experimental animal health, is even resulted in experimental animal acid poisoning.Following table is CO2 levels and organism
The relationship of physiological reaction.
| CO2Concentration | Physiological reaction |
| 350~450ppm | With general outdoor environment |
| 350~1000ppm | It is with fresh air, it breathes smooth |
| >10,00ppm | It is muddy to feel air, and starts to feel drowsy |
| >20,00ppm | Feeling is had a headache, drowsiness, dull, attention can not be concentrated, be palpitated quickly, mild nausea |
| >50,00ppm | It may cause severe depletion of oxygen, cause permanent brain damage, stupor, even death |
Currently, reducing CO2The method of concentration there are two main ways:
1. gas dilution passes through injection N2To dilute the CO in particular space2, and pass through O2The control of concentration reaches mesh
Scale value.The main deficiency of which is:
Due to CO2Boundary value be ppm grades, then need to inject a large amount of N2And O2To reduce CO2Concentration, cost is very high,
Low efficiency.
2. being directly placed into a large amount of adsorbents to be adsorbed.The deficiency of which is:
Adsorbent utilization rate is not high, causes to waste.
Summary of the invention
To solve the deficiency in above-mentioned prior art, the present invention provides CO in a kind of enclosed environment2Control dress
It sets, improves the utilization rate of adsorbent, reduce costs.
The purpose of the present invention is what is be achieved through the following technical solutions:
CO in a kind of enclosed environment2Control device, the control device includes closed rearing-box；The enclosed environment

The top of the rearing-box is arranged in chamber, multiple chambers；The side of the chamber faced in the rearing-box
With switch, whether the switch is connected to inside the chamber interior and the rearing-box for controlling, it is suitable in the chamber
Place CO2Adsorbent；
Sensor, the sensor are used to detect the CO in the rearing-box2Content A1、CO2Generation rate A2And O2's
Content B, and it is transmitted to processor；
Processor, the processor is according to the A received1、A2And B obtains area S:
Work as A1When > C,Work as A1When≤C, k=0；D is rearing-box
Interior CO2Content safety value, and C ∈ (0, D)；
Probe unit, the probe unit are used to detect the present position of animal in the rearing-box, and it is single to transmit control
Member；
Control unit, described control unit adjust the switch, so that the cavity bottom above the present position is opened
The sum of the area of mouth is matched with the area S.
The object of the invention is also to provide CO in the enclosed environment based on above-mentioned control device2Control method, should
Goal of the invention has the technical scheme that
According to CO in the enclosed environment of above-mentioned control device2Control method, the control method the following steps are included:
(A1) CO in sensor detection rearing-box2Content A1、CO2Generation rate A2And O2Content B, and transmit everywhere
Device is managed, the processor exports area S；
Probe unit detects the present position of animal in the rearing-box, and transmits control unit；
(A2) control unit adjustment switch so that the sum of area of opening of cavity bottom above the present position with
The area S matching；
(A3) CO in the indoor adsorbent absorption rearing-box of the chamber opened2, thus by CO in rearing-box2Content reduce
To level of security.
Compared with prior art, the device have the advantages that are as follows:
1. realizing accurate control: determining the chamber (adsorbent absorption) for needing to open according to the parameter of gas in rearing-box
Area, further according to the present position (CO at this position of the animal detected2Content is high), it goes to open the chamber above present position
Room, so that adsorbent exposure, to reduce the CO at animal present position2Content, so that being in level of security；
2. without using N2, reduce costs significantly；
3. realizing the capacity prediction of experimental animal in different volumes rearing-box.
