Life support device, pressurized cabin and vacuum train

Abstract

Disclosed are a life support device, a pressurized cabin and a vacuum train. The life support device comprises an oxide filter element for absorbing carbon dioxide and moisture in the air and generating oxygen, and regulating the oxygen content and carbon dioxide content in an airtight manned space by chemical reaction, and a purification filter element for deodorizing and / or filtering particulatematters. The air in the airtight manned space sequentially passes the oxide filter element and the purification filter element to become clean air. The invention also discloses the pressurized cabinand the vacuum train. On one hand, the life support device, the pressurized cabin and the vacuum train can greatly improve the living demand and comfort of people in an airtight environment and the exhaled exhaust gas can be purified by the fresh air, which is beneficial to the health of people, and the purpose of deodorizing, sterilizing and keeping the space dry can also be achieved, on the other hand, electricity and power are not needed, which greatly saves electricity consumption and power consumption.

Description

technical field [0001] The invention relates to the technical field of life support, in particular to a life support device, a pressurized cabin and a vacuum train. Background technique [0002] Since the actual average daily oxygen consumption of a person is about 0.75 kg, 1.0 kg of carbon dioxide is exhaled. Normally, the oxygen content in the inhaled air is about 20.9%, and the oxygen content in the exhaled gas is about 16-17%, so people need to inhale 12-15m³ of fresh air every day. High-quality air conditioners require the oxygen content of the air to reach more than 20.5%. If the exhaled exhaust gas is mixed with fresh air in an airtight space, the actual required fresh air volume will reach 15-30m³ / hour*person. When the oxygen content in the air is lower than 20%, people will feel uncomfortable, easy to fatigue, and even cause respiratory system lesions or patients to get sick. Oxygen content in the air in the occupational health standard is 18%, lower will seriousl...

Problems solved by technology

[0005] Although compressed air or compressed oxygen can be used to supplement breathing oxygen, the vacuum pipeline cannot accept the discharge of exhaust gas. Even if oxygen is provided, the pressure in the car body will increase, and the carbon dioxide content will increase, leading to acidosis; and various odorous substances accumulate, unbearable

Moreover, due to the extremely fast speed of the vacuum train, there is no contact with the vacuum pipe and the track, and there is no device such as a pantograph to obtain sufficient power from the outside. The pressurized cabin of the train can only rely on the battery for power supply, but the battery increases the weight of the car body , and the energy density is limited, it cannot provide enough power to compress and store the waste gas
