Abstract

The invention discloses an airborne passive air intake special pollution real-time rapid monitoring system, which relates to an airplane special pollution control system. The system comprises an engine, a primary filter, a pipeline branch control valve, an environment control system, a monitoring instrument and an airplane cockpit which are sequentially communicated through a pipeline. The systemfurther comprises a high-efficiency filter. The high-efficiency filter is communicated with a pipeline between the primary filter and the pipeline branch control valve through an inlet branch, and thehigh-efficiency filter is communicated with a pipeline between the pipeline branch control valve and the environment control system through an outlet branch; a high-efficiency filter branch control valve is arranged on the inlet branch; and the monitoring instrument is connected with the high-efficiency filter branch control valve through a first signal feedback path, and is connected with the pipeline branch control valve through a second signal feedback path. Real-time opening or closing of each branch of the airborne filter device is controlled through signals transmitted by the monitoringinstrument, so that the airborne filter device does not need to be opened for a long time, and energy is saved.

Description

technical field [0001] The invention relates to the field of aircraft special pollution control and monitoring, in particular to an airborne passive air intake special pollution real-time rapid monitoring system. Background technique [0002] Existing aircraft special pollution control is to install a filtering device behind the engine bleed air, and the bleed air of the engine passes through the filter device to realize the filtering of the bleed air and remove solid particle pollutants therein. Existing aircraft on-board filter devices cannot judge whether to open the on-board filter device according to the concentration of external solid pollutants, so the on-board filter device needs to be turned on for a long time, which consumes more energy. Contents of the invention [0003] The purpose of the present invention is to provide a real-time rapid monitoring system for airborne passive air intake special pollution, to solve the problems in the above-mentioned prior art, ...
