Technical Field

The invention belongs to the technical field of advanced manufacturing and automation, particularly relates to an advanced rail transit vehicle, and particularly relates to an intelligent rail transit particulate matter control system based on electromagnetic enhanced adsorption.

Background

In the urbanization process and the underground traffic development are accelerating today, the particulate matter pollution degree in urban subway stations is an important basis for evaluating the urban environment quality, and the urban subway stations are increasingly concerned. As urban underground rail transit, subways are the first choice of transportation for people to go out nowadays.

The subway environment is used as a special traffic microenvironment and has the following typical characteristics: (1) the subway environment is relatively closed, the circulated air quantity is limited, and pollutants are not easy to diffuse and dilute; (2) the pollutants are complex in type, and have molecular pollutants and solid floating particles, and the synergistic effect of the molecular pollutants and the solid floating particles aggravates the harm to human bodies; (3) environmental control and guarantee mainly depend on the ventilation air-conditioning system, and each apparatus operates in the stable level for a long time, the pollutant is apt to pile up; (4) the air pollution of the subway environment almost covers all age groups, and the number of people is large.

Subway tunnel can produce a large amount of particulate matters because its operational environment causes its operation in-process, and the source of particulate matter includes external source and internal source, specifically as follows:

the external source is related to street traffic and mainly takes atmospheric particulates as the main;

the internal source is closely inseparable with the mechanical abrasion during the operation and braking of the train, mainly takes abrasion particles as the main part and contains a large amount of metal particles. The two parts are mixed with each other to form special subway particulate matters.

No matter where the particulate matters come from, the particulate matters can enter a platform through a gap of a shielding door along with the running air flow of the train or enter a compartment through a fresh air system of a subway compartment. Because the subway particulate matter contains a large amount of metallic elements, compare typical atmospheric particulates, its toxicity is stronger, and is bigger to the harm of human body. The influence of tunnel particles on the health of passengers and workers is long-term and concealed, but the damage to human bodies is direct, and the influence seriously influences the health of the passengers and workers.

Meanwhile, the increase of particulate matters in the tunnel can threaten the driving safety of the metro vehicle, the accumulation of the particulate matters influences the normal use of the electrical equipment in the train and the tunnel, the sensitivity of the electrical equipment is reduced in the long term, the failure rate of the metro train is increased, the maintenance cost of the train is improved, and finally, the driving accidents can be caused. In addition, subway power supply adopts the high voltage direct current power supply, and tunnel air particulate matter concentration is higher, probably leads to the air to be punctured by high voltage, causes the electrified passenger life that threatens of train automobile body.

Therefore how high efficiency clears up the tunnel particulate matter will become the important measure of guaranteeing driving safety, maintaining passenger and staff healthy, also is the important problem that awaits solution in the rapid development process in the rail transit field.

At present, a subway tunnel particle control method, in particular to a method for treating pollution of a subway tunnel at home and abroad, has two major directions, one is a movable subway tunnel cleaning vehicle, and the other is manual washing and dust collection. The movable subway tunnel cleaning equipment is divided into the following steps according to the purification method: a method combining dust collection and blowing, a method combining dust collection, blowing and water spraying washing, a method combining vacuum dust collection, rolling brush cleaning and high-pressure water cleaning and the like. The method has a fatal defect that a certain effect can be achieved only by consuming a large amount of electric energy and running at a low speed, so that the running time of equipment is too long, and the cleaning efficiency is too low; in addition, the implementation of the scheme can be realized only by operating special purification train equipment in the tunnel, so that the huge hidden danger that the subway train cannot normally operate due to the fact that electrical equipment on the inner wall of the tunnel is scraped or the equipment per se fails occurs in the operation of the purification equipment, and great disadvantages are brought to the operation of the train and the safety of passengers; each urban subway operator is provided with a special tunnel particle cleaning department, basically adopts modes such as manual washing, dust absorption and the like, and the frequency is generally divided into 2 months/1 time, 3 months/1 time and 6 months/1 time according to different subway line running conditions.

The method has the defects of low working efficiency, special empty window period, long tunnel cleaning lasting days due to the fact that the empty window period is only about 3-6 hours every day, large amount of manpower is needed for cooperation, the tunnel cannot be cleaned effectively, waste water containing metal particles cannot be completely recycled due to the fact that the waste water is flushed in the tunnel, and part of the waste water enters the ground to cause underground water pollution.

In summary, the existing tunnel particulate matter treatment technology still needs to be improved.
