Description

Subway electric rail car equipped with dust removal system}

The present invention relates to a subway electric vehicle equipped with a dust collecting device for removing the fine particles and dust present in a large amount in the subway station and subway tunnel.

In general, in the case of subways, dust caused by friction between rails and train wheels, and dust sinking to the floor, due to the flow of air due to the operation of the subway, is generally used. It is known to be polluted several times to ten times more than outside air.

In particular, when the subway enters the history of waiting for passengers, air flows by the moving subway to move a large amount of particles (branches) existing in the subway tunnel into the history.

Therefore, passengers using subways and related personnel operating subways may suffer from respiratory diseases due to exposure to contaminated air. In particular, iron dust generated by friction between rails and train wheels may be inhaled through the respiratory system. This can seriously harm your body.

In order to prevent the damage of passengers and related persons who use the subway by the polluted air as described above, the cleaning vehicle is periodically put in and cleaned inside the tunnel, but it is difficult to clean by the continuous operation of the subway. In a short time, subway tunnel spaces are exposed to polluted air.

In order to solve this problem, a technique for collecting fine particles in a subway tunnel space when a vehicle is installed by installing a dust collector on one side of a subway, such as a domestic dust collector of Korean Patent No. 725996, has been provided.

The provided vehicle dust collector of Patent No. 725996 is largely composed of a collecting plate for collecting dust (fine particles), a thruster for dropping off the dust aggregates grown on the collecting plate, and a filter for collecting the dropped dust aggregates.

The vehicle dust collector of Patent No. 725996 configured as described above has the disadvantage of periodically replacing the filter frequently, the disadvantage of increasing the maintenance cost due to the frequent replacement of the filter, and the fact that the differential pressure is prevented by the large number of dust aggregates collected in the filter when the filter is used. There is a problem that the removal efficiency of dust (fine particles) is low due to the problem that the air flow is bad.

Conventionally, various technologies are provided as dust collectors for removing fine particles in air, and among them, cyclone dust collectors, electrostatic precipitators, and filter cloth dust collectors are widely used, and thus, cyclone dust collectors, electrostatic precipitators, and filter cloth dust collectors are used. Many techniques have been developed.

In general, the cyclone dust collector is a dust collector that removes only the relatively large particles contained in the air by gravity to supply the air to rotate there is a disadvantage that can not remove the fine particles.

The electrostatic precipitator is a dust collecting device for generating a large amount of ions by high voltage to charge the fine particles contained in the air, and the charged fine particles to pass through the dust collecting plate formed with an electrostatic force to collect the charged fine particles to the dust collecting plate, When ions are generated, a large amount of ozone is generated by a corona discharge (low temperature plasma) generated between the discharge plate and the discharge electrode, and thus there is a disadvantage that it cannot be used in an indoor space where a person exists.

The filter cloth dust collector is a dust collector that removes fine particles contained in the air by passing air through the filter, and the filter replacement cycle is too fast in a serious pollution place, and when the filter replacement cycle is delayed, the differential pressure is large and the dust collection effect is generated. Has the disadvantage of falling sharply.

The present invention was invented to solve this problem,

The purpose is to remove dust particles and dust in the air in the tunnel while the subway moves by installing a dust collector in a subway train consisting of a plurality of vehicles.

In addition, the use of an electrostatic precipitator to charge and collect the fine particles and dust in the air in the tunnel, the purpose is to provide an electrostatic precipitator without the generation of ozone in the generation of ions due to the nature of the space where people stay in history.

In addition, by using a cyclone dust collector and an electrostatic precipitator to remove the fine particles in advance in the air supplied to the filter cloth dust collector using a filter, the purpose of reducing the differential pressure by reducing the concentration of fine particles in the air, and to improve the dust collection capacity.

According to an aspect of the present invention,

It is installed in a vehicle in front of a subway electric car consisting of a plurality of vehicles, the inlet is formed in the front, the outlet for discharging the air to remove the fine particles contained in the air sucked into the inlet is formed, between the inlet and the outlet It is configured to include an electrostatic precipitator for removing the fine particles contained in the air sucked into the inlet.

The electrostatic precipitator generates ions to charge the microparticles, and removes the charged microparticles by an electrostatic precipitating method. An electrostatic precipitator is used to collect the fine particles by generating ions by a corona discharge, which is commonly used. Alternatively, an electrostatic precipitator using an ion generator made of carbon fiber or carbon fabric is used.

When the electrostatic precipitator using the corona discharge is used, the ozone treatment unit is included.

The dust collector may be configured to further include one or both of cyclone dust collector, filter cloth dust collector.

The electrostatic precipitator using the ion generator made of carbon fiber or carbon fabric is composed of a single stage electrostatic precipitator or a two stage electrostatic precipitator.

The first stage electrostatic precipitator includes an ion generator made of carbon fiber or carbon fabric, a high pressure supply device for applying a high voltage to the ion generator, and a dust collecting plate for collecting fine particles charged by ions generated in the ion generator. In the electrostatic precipitator, an ion generator for generating ions is usually installed inside the dust collecting plate.

The two-stage electrostatic precipitator includes a charged portion in which an ion generator for generating ions is installed, and a dust collector provided with a dust collecting plate for collecting fine particles charged in the charged portion by an electrostatic dust collection method.

A blower may be further installed to allow the air to be sucked into the suction port while the subway stops, and a rectifier filter is further installed to rectify the contaminated air sucked into the suction port. The rectifier filter is usually installed at the front end of the electrostatic precipitator.

In the subway electric vehicle equipped with the dust collector of the present invention, the dust collector is installed in front of the vehicle in front of the vehicle so that the air sucked into the inlet by the movement of the subway during the operation of the subway is easily sucked, and the fine particles and the dust in the dust collector. By this removal, the air in the tunnel is cleaned, and thus, the health of passengers and people in the subway can be promoted.

In addition, by using the carbon fiber or carbon fabric ion generator in the electrostatic precipitator used in the dust collector, it is possible to prevent the ozone damage to people by not generating ozone when the ion is generated.

In addition, since the air from which the fine particles are first removed from the electrostatic precipitator is sucked into the filter cloth dust collector using the filter, it is possible to reduce the differential pressure caused by the filter cloth dust collector.

In addition, the present invention is characterized in that the dust collecting performance is improved by properly combining the cyclone dust collector, the electrostatic precipitator, and the filter cloth dust collector.
