Multi-stage air filtering device for urban rail vehicle

Abstract

The invention discloses an urban rail vehicle air multi-stage filtering device which comprises a dust removal chamber, a dust removal wetting part is installed in the dust removal chamber, an air inlet is formed in one side of the dust removal chamber, the other side of the dust removal chamber communicates with a first-stage drying chamber, a first filtering plate is fixedly installed between the first-stage drying chamber and the dust removal chamber, and a plurality of air gathering buckets are installed in the first-stage drying chamber; the air gathering buckets are fixedly connected with the first filter plate, the end, away from the first filter plate, of each air gathering bucket communicates with a first drying part, the first-stage drying chamber communicates with an air supply chamber, a plurality of air supply fans are rotationally connected into the air supply chamber, the side, away from the first-stage drying chamber, of the air supply chamber communicates with a second-stage drying chamber, and a second drying part is fixedly arranged in the second-stage drying chamber. The second-stage drying chamber is communicated with a disinfection chamber, and the disinfection chamber is communicated with an air outlet; the air purifier is simple in structure, convenient and fast to operate, capable of removing dust particles in air and preventing the dust particles from affecting the filtering effect, and good in air filtering effect.

Description

technical field [0001] The invention relates to the technical field of air filtration for rail vehicles, in particular to a multi-stage air filtration device for urban rail vehicles. Background technique [0002] Rail vehicles are of great significance to the development of urban transportation. Rail vehicles can greatly relieve the pressure of ground public transportation and provide greater potential for urban economic development. The advantages of rail transit lie in high speed and large carrying capacity. Rail transit has a large carrying capacity, but at the same time, it has a great challenge for the internal air purification system, especially the air disinfection and filtration ability is weak, and the confined space can easily lead to the rapid spread of respiratory diseases, so it is necessary to use vehicle air filtration devices, but In the prior art, multi-stage filter plates are generally used for filtration, and the filtering effect is poor, and a large numbe...

Problems solved by technology

The carrying capacity of rail transit is large, but at the same time, it has a great test for the internal air purification system, especially for the weak disinfection and filtration capacity of the air. Confined spaces are easy to cause the rapid spread of respiratory diseases, so it is necessary to use vehicle air filtration devices, but In the prior art, multi-stage filter plates are generally used for filtering, and the filtering effect is poor, and a large amount of dust particles in the air cannot be processed or the processing effect is poor, resulting in the dust particles easily blocking the filter plates, so there is an urgent need for a filter for the air. Multi-stage filter device with good dust treatment effect and sufficient filtration
