Carbon dioxide absorption device and method

Abstract

The invention discloses a carbon dioxide absorption device and method. The device comprises an air chamber, one side of the air chamber is connected with an air distributor, the other side of the air chamber is connected with a shell, and an absorption tank is installed in the shell and used for absorbing and purifying carbon dioxide in a cabin; the air chamber comprises an air chamber body, a first air cavity is formed in the side, close to the air distributor, of the air chamber body, the side, away from the air distributor, of the first air cavity communicates with a third air cavity and a second connector, the second connector is connected with an air inlet piece, and the third air cavity communicates with the inner cavity of the shell. The device is simple and reasonable in structural design, light in weight, convenient to disassemble and maintain and high in universality, oxygen can be introduced into the air chamber during use, meanwhile, the nozzle and the spray pipe are constructed according to the Venturi principle, when oxygen is introduced, gas in the cabin can be driven to circularly flow through the absorption tank, absorption of carbon dioxide in the cabin is accelerated, and then the oxygen can be mixed with gas discharged from the absorption tank and then discharged from the air distributor so that the contents of carbon dioxide and oxygen in the cabin body are uniform.

Description

technical field [0001] The invention relates to the technical field of pressurized cabins, in particular to a carbon dioxide absorbing device and method. Background technique [0002] In the process of emergency rescue and emergency rescue, the rescue of the injured is always the top priority. It is easy to fold, has a small storage space, and is easy to carry. Rescue-type soft pressurized cabins are common rescue equipment. Due to the functional requirements of the soft air pressurized cabin itself, the soft air pressurized cabin achieves the functional requirement that the pressure in the cabin is greater than the external atmospheric pressure through good sealing performance, that is, the soft air pressurized cabin cannot be easily closed after it is completely closed. gas exchange with the outside world. [0003] In order to ensure that the escape personnel in the pressurized cabin can continue to survive, it is necessary to supplement the space in the soft air pressuri...

AI Technical Summary

Problems solved by technology

[0004] However, when the above-mentioned device is used, it only pays attention to the transfer and absorption of carbon dioxide in the air, and an additional oxygenation device is needed to distribute the air. The content of carbon dioxide and oxygen in the cabin is uneven, which may easily cause the local carbon dioxide concentration to be too high, and the above-mentioned device is equipped with a circulation fan. , there is noise when working, and it will cause the device to occupy too much area, which is not conducive to the use of oxygen chamber
