Problems solved by technology

[0003] For these non-sustained pollution sources, if only pollutant treatment devices are installed in the environmental control system (generally by means of filtration or adsorption), it will inevitably increase the system flow resistance under all working conditions, resulting in waste

Abstract

The invention relates to a double-channel switching pipeline type pollutant treatment device. The double-flow-channel switching pipeline type pollutant treatment device comprises a central flow channel and a peripheral flow channel, the central flow channel is located in the center of the pipeline type pollutant treatment device, a valve element used for achieving on-off of the central flow channel is installed in the central flow channel, the peripheral flow channel is nested outside the central flow channel, and the central flow channel is communicated with the peripheral flow channel. A filter material is arranged in the peripheral flow channel, and the central flow channel and the peripheral flow channel are separated by a cylindrical grid plate. According to the technical scheme, themethod has the beneficial technical effect that the low flow resistance characteristic and pollutant control under different upstream pollution states are both considered.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a pipeline-type pollutant treatment device with double-channel switching. Background technique [0002] The air source of the traditional civil aircraft environmental control system comes from the engine bleed air, and the quality of the bleed air will directly affect the quality of the air sent downstream to the cabin. However, there are many types of pollutants in the bleed air, and the pollution sources are non-continuous, and there will be great differences with different flight stages. For example, fuel vapor or lubricating oil vapor will escape to the air inlet when the engine is just started or shut down, but it is difficult to occur under other working conditions; atmospheric pollution from outside the cabin, such as PM2.5, PM10, nitrogen oxides, etc., will When waiting on the ground, it is sucked into the bleed port with the engine, and the content of these substances...
