Rail vehicle with carriage air purification function

Abstract

The invention belongs to the technical field of rail transit, and discloses a rail vehicle with a carriage air purification function. The rail vehicle comprises carriages and air purification devicesarranged in the carriages, the air purification devices comprise shells, air inlets, air outlets, fans and filters, wherein the air inlets and the air outlets are formed in the shells, the fan are arranged in the shells, the filters are arranged between the air inlets and the air outlets, the filters comprise filter screens, carbon fiber filter layers and graphene-based HEPA filter layers which are sequentially arranged from the air inlets to the air outlets, the air purification devices further comprise dust scraping plates used for scraping dust on the windward sides of the filter screens, the dust scraping plates are movably arranged on the shells through moving mechanisms, and the bottom surfaces of the dust scraping plates are parallel to the windward sides of the filter screens. According to the rail vehicle with the carriage air purification function, a structure which is specially used for clearing accumulated impurities on the filter screens is arranged, so that cleaning by maintenance personnel is facilitated, then the dust filtering efficiency and the dust filtering effect are improved, and the use performance of the air purification devices is ensured.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rail vehicle with a compartment air purification function. Background technique [0002] A rail vehicle is a means of transportation and transportation. Common rail vehicles include railways, subways, light rails and trams. With the diversified development of train and railway technology, more and more types of rail transit have emerged, not only in long-distance land transportation, but also in short- and medium-distance urban public transportation. [0003] At present, the air purification in the rail vehicle compartment is mainly solved by the air-conditioning filter screen, and there are also special air purification devices; The casing, the air inlet and the air outlet arranged on the casing, the fan arranged in the casing, and the filter arranged between the air inlet and the air outlet, the filter is composed of multiple filter layers, from the air inlet ...

AI Technical Summary

Problems solved by technology

[0003] At present, the air purification in the rail vehicle compartment is mainly solved by the air-conditioning filter screen, and there are also special air purification devices; The casing, the air inlet and the air outlet arranged on the casing, the fan arranged in the casing, and the filter arranged between the air inlet and the air outlet, the filter is composed of multiple filter layers, from the air inlet The direction to the air outlet includes a filter, a carbon fiber filter layer, and a graphene-based HEPA filter layer; the filter is used as the first filter structure to initially filter large particles of dust such as fibers and dust, as well as hair and scalp falling from the human body. During use, it was found that the air-facing side of the filter screen (that is, the side that is close to the outside world and the first contact with the air) is easy to accumulate impurities. Since the above-mentioned device lacks a special structure for cleaning the accumulated impurities, it is not convenient for maintenance personnel to clean it. The accumulated impurities block the entry of external air, reduce the dust filtration efficiency and dust filtration effect, and affect the performance of the dust removal device
