Aeration air intake apparatus for high-speed train

Abstract

The invention relates to an air ventilating and air intake method of a high speed train and a device thereof. The device includes an air course body used for communicating with a ventilating device ofthe high speed train; at least one air inlet is arranged on the air course body; a cylinder filter consisting of an upper bottom plate, a lower bottom plate, an inner layer protection screen and a lower layer protection screen is fixed below each air inlet; the device also includes a seal cushion arranged between the filter and the air course body; a paper filter element is adopted by a filter element of the filter; the lower bottom plate of the filter is directly fixed on the air course body by a stud bolt. The outdoor fresh air enters into a ventilating pipeline after passing through an airinlet device with a paper filter element, then is supplied to the ventilating device by the ventilating pipeline and finally enters an air conditioning set after being mixed with return air, therebyfeeding the fresh air after being filtered into the carriage of the high speed train and maintaining the freshness of the air in the carriage. The structure and the method are adopted to have remarkable effect on dust removal simultaneously when ensuring that the amount of air inlet is large, and have high filtering efficiency and ensure the air quality in the carriage of the high speed train, besides, the paper filter element structure is easy to be washed and is convenient for being maintained and exchanged.

Description

technical field [0001] The invention relates to a device for exchanging fresh air, in particular to an air intake device applied to exchanging air for high-speed trains. Background technique [0002] In the prior art, the ventilation method of the air-conditioning unit on the high-speed train is mainly to utilize a simple air inlet with a common dust filter to inhale the fresh air outside and discharge the dirty air in the room, so that the air in the high-speed train compartment The air is always fresh. [0003] Most of the ventilation devices installed on the high-speed train are arranged on the top of the high-speed train, and for saving the space of the car body, it can also be placed at the bottom of the high-speed train car body. When the ventilating device is placed at the bottom of the high-speed train, because it is closer to the ground, and during the running of the high-speed train, a lot of dust will be brought up due to the faster speed of the train, the air in...

AI Technical Summary

Problems solved by technology

When the ventilating device is placed at the bottom of the high-speed train, because it is closer to the ground, and during the running of the high-speed train, a lot of dust will be brought up due to the faster speed of the train, the air inlet of the ventilating device in the prior art only adopts ordinary Dust filters, such as non-woven fabrics, cannot effectively block the entry of dust, and the filtration efficiency is low, especially in areas with strong wind and sand, a large amount of dust will enter the compartment through the air inlet pipe, causing environmental pollution in the compartment
