Description

Platform dust collector {ELECTRIC PRECIPITATOR APPARATUS FOR PLATFORM OF STATION}

The present invention relates to a dust collecting device for collecting dust, and more particularly, to a dust collecting device installed between platforms such as subways and trains.

Devices for removing particulate contaminants such as fine dust contained in the air have been developed in various ways, and one of them, the electric precipitator, generates a large amount of electrons (ions) by generating corona discharge, and the generated electrons (ions) Ionizes the air molecules around it. Air molecules ionized in the electrostatic precipitator are combined with particulate matter (fine dust, etc.) contained in the air, and the particulate matter is charged (having electrical polarity), and the charged particulate matter is trapped in the dust collecting electrode by electrostatic force.

The electric dust collector has a structure in which a dust collecting electrode is electrically grounded at regular intervals, and a discharge electrode to which a high voltage is applied is installed between the dust collecting electrode and the dust collecting electrode. When a high voltage is applied to the discharge electrode, a corona discharge phenomenon occurs between the discharge electrode and the dust collecting electrode, and generally, an electrical conductor material is used for both the dust collecting electrode and the discharge electrode.

Since a corna discharge is formed between the discharge electrode and the dust collecting electrode, there is a problem that a lot of vibration occurs in the discharge electrode and the dust collecting electrode. In addition, when the distance between the discharge electrode and the dust collecting electrode increases, the dust collection efficiency decreases, and a problem arises that a large voltage must be applied for corona discharge. If the distance between the discharge electrode and the dust collecting electrode is reduced, the dust collection efficiency is improved, but if the discharge electrode and the dust collecting electrode are not firmly supported, there is a problem that the discharge electrode and the dust collecting electrode may be shorted.

Recently, the subway is used as a major means of transportation along with buses, and since the subway is superior to other means of transportation in terms of safety, accuracy of time, and economy, it plays a very important role in the daily life of the people.

However, the rapid increase of passengers and the intensification of air pollution are increasing pollutants such as fine dust, carbon dioxide (CO2), sulfur dioxide (SO2), and carbon monoxide (CO), resulting in a sharp decline in air quality inside the tunnel.

Among the pollutants in the air inside the subway tunnel, a particularly serious one is the high concentration of fine dust that exists inside the subway tunnel. The fine dust contained in the air inside the subway tunnel in Korea is in a high concentration of about 300-400㎍/㎥ during the time the train is running, and the high concentration fine dust inside the tunnel can flow into the platform.
