Air cleaning system in closed cabin and the control method

Abstract

A closed-in compartment air cleaning system and a control method thereof are disclosed, wherein the system id composed of three subsystems: a main air cleaning system, namely called as the adsorbing air cleaning system; a vice air cleaning system, namely called as the catalytic combustion air cleaning system; a linking combinatorial system, also called as the desorption reproduction system, having the advantages of combining the adsorption, the desorption, the catalytic combustion, to integrate the closed-in compartment air cleaning perfect system. The system adopts PLC microcomputer planed as a whole to control each link, which is of high efficiency, energy saving, environmental protection and sanitation. The air cleaning system and the control method can be designed into the air cleaning device with different specification according to the requirement, which can be used in the nuclear submarine, the AIP submarine, the conventional submarine, the manned spacecraft, the underground anti-aircraft defense and the air cleaning process of the air standard plant, and is an ideal closed-in compartment air cleaning system and a control method.

Description

1. Technical field: [0001] The invention relates to an air purification system and a control method thereof, in particular to an air purification system and a control method for a closed cabin, which is suitable for air purification treatment of submarines, space manned spaceships and underground air defense facilities. 2. Background technology: [0002] At present, there are two kinds of air purification methods that are actually used in airtight cabins polluted by organic matter. The first is the catalytic combustion method, that is, the catalytic combustion system; air filter. Both of these two treatment methods have certain prominent shortcomings. The working temperature of the catalytic combustion method is as high as 315°C, and the power consumption and water consumption are relatively large. For example, the treatment air volume is 800m 3 The maximum power consumption of the combustion device per hour is 50kw, and the consumption of cooling water at 6°C is 2t / h. The ...

Problems solved by technology

Both of these two treatment methods have certain prominent shortcomings. The working temperature of the catalytic combustion method is as high as 315°C, and the power consumption and water consumption are relatively large. For example, the treatment air volume is 800m 3 The maximum power consumption of the combustion device per hour is 50kw, and the consumption of cooling water at 6°C is 2t/h. The power consumption of cooling water is not included in the above power consumption. The volume of the combustion device is large (about 2.85m 3 ), the structure is complex, and it is difficult to achieve perfect heat preservation to reduce the surface temperature of the device
