Problems solved by technology

The oxygen replenishing method currently used in the airtight cabin is mainly electrolyzed water, which generates a large amount of hydrogen at the same time as the oxygen is produced. The leakage of hydrogen will cause serious safety hazards. Carbon dioxide capture mainly uses absorbents, which need to carry a large amount of absorbents, occupying Valuable space in the cabin also reduces the endurance of the equipment
Existing air purification and oxygen supply equipment are difficult to comprehensively improve indoor ambient air quality

Embodiment 1

[0019] In this embodiment, the specification of fan 4 is 500L / min, the specification of DC power supply 3 is 5V*200A, the volume of electrolytic cell is 4L, and LiCl is used as the initial liquid salt electrolyte, wherein Li 2 O (2.0 wt%) was used as a gas absorbent. The device is used for air cleaning and oxygen supply in a newly decorated 10 square meter office room with 4 staff members. The oxygen concentration at the air outlet is greater than 22%, the carbon dioxide concentration is lower than 0.01%, and the formaldehyde and VOCs concentrations are 0 (less instrument detection limit); controlled by the computer 1, the air can be cleaned, and the carbon dioxide concentration in the whole room can be controlled below 0.04%, and the oxygen concentration can be controlled at about 21%.

Embodiment 2

[0021] Fan 4 specification is 1m in the present embodiment 3 / min, the specification of the DC power supply 3 is 5V×1000A, and the volume of the electrolytic cell is 100L. Use the device for 60m with a crew of 10 3 In the simulated airtight cabin, the oxygen concentration at the air outlet is greater than 24%, and the carbon dioxide concentration is lower than 0.02%. Controlled by the computer 1, the air in the simulated airtight cabin can be cleaned, and finally the carbon dioxide concentration in the cabin can be controlled below 0.04%. Controlled at around 21%.

Embodiment 3

[0023] Fan 4 specification is 10m in the present embodiment 3 / min, the specification of DC power supply 3 is 5V×10kA, and the volume of electrolytic cell is 1m 3 . The device is used in a movie theater with 200 spectators, the oxygen concentration at the air outlet is greater than 24%, and the carbon dioxide concentration is lower than 0.02%; controlled by the computer 1, the air in the movie theater can be cleaned, and finally the carbon dioxide concentration in the movie theater can be controlled at Below 0.04%, the oxygen concentration is controlled at about 21%.

Abstract

The invention discloses an intelligent air purification and oxygen supplementing method. According to the method, carbon dioxide and harmful gas in air are captured and absorbed through a liquid saltelectrolyte, and are converted into harmless products and oxygen through electrolysis. The invention further discloses an intelligent air purification and oxygen supplementing device. The intelligentair purification and oxygen supplementing device comprises an automatic control system and an air purification and oxygen supplementing electrolytic tank, wherein the automatic control system comprises a computer, a direct-current power supply and a fan; and the computer is electrically connected with the direct-current power supply and the fan. The intelligent air purification and oxygen supplementing method has the beneficial effects that carbon dioxide entering the electrolyte can be electrolyzed into oxygen by the device, so that air circulation is realized, and the harmful gas can be captured and absorbed and harmless; and the intelligent air purification and oxygen supplementing method can be used for air purification and oxygen supplementing of an underwater naval vessel closed cabin, an underwater detector closed cabin, an amphibious armored closed cabin, a spacecraft closed cabin, an outer star base, a public place and a residential room.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an intelligent air purification method and device for supplementing oxygen. Background technique [0002] Modern humans live indoors for more than 80% of their time on average, and indoor air quality is an important factor that affects people's health and life expectancy. Due to the small space and slow gas exchange with the outside world, the air quality in public places, office places, and residential places is poor, and the air quality inside airtight cabins (such as underwater ships, submarines, and spacecraft) is even worse: on the one hand, the oxygen content in indoor air On the other hand, the human body and indoor machines, furniture, and decoration materials emit a large amount of toxic and harmful gases, including volatile organic compounds VOCs, NOx, and NH 3 , CO, H 2 S et al. An air environment with low oxygen content can cause the cognitive function of the human ...
