DUST MANAGEMENT SYSTEM THROUGH STREET LIGHT POLE AND INCREASES THE UTILIZATION OF COAL

mechanical engineering

The objective of this research describes the reduction of air pollution on the road and introduces a design model which helps to do it. To control air pollution on the roadside, a model comprises of a fan which is fitted to the street light pole, extracts dust particle from the road and collect it inside that pole through a duct. Here interesting thing is that the bottom side of the hollow and circular cross-section area (hollow cylinder shape) of the street light pole is used as a dust collecting bag. This concept is useful for extracting dust particle from the dusty urban road, road in open cast coal mines, high traffic road, etc where the street light pole is available. Till now the electric pole is useful for street lighting and power transmission only but the continuous increasing of air pollution on the road needs the regular monitoring and control, so we need to give one more work to an electric pole in future i.e. holding dust extractor unit. A need for electric supply for running a fan is also an easy task with this design because it’s already an electric pole. It’s not to say wrong that the Roads plays a vital role to build a good infrastructure of the city but today it is a major reason for air pollution. For monitoring and controlling of a dusty road, interesting thing is that for the installation of this design we don’t need to install a pole near the roadside it is already available for street lighting and only we need to fit collecting system on it. The design also uses the speed of vehicles moving on the road, the extraction of dust by fan is more when the vehicle moving in high speed because turbulence occurs in the air and dust start shifting from one place to another place which leads to strikes the fan with high speed which allows setup simple in design and uses low power, only a fan. Dust removing gate which is fitted on end of the bottom side of the pole, collected dust inside the pole is removing by means of hand, vacuumed, pipeline or conveyor. The number of pedestrians and riders are decreasing day by day because of bad air quality on the road; also dust particle flying on the road creates judgment problem for drivers and sometimes it leads to a major accident. The extraction of this dust particle from the road by collecting unit provides clear road and good visual coordination for the drivers. This abiotic variable (pollution) is more harmful to our ecosystem. Every step against pollution is very important for our environment.
