AIR POLLUTION AND THE FILTRATION PROCESSING SYSTEMS FOR THE BITUMINOUS MATERIAL PLANTS

It is known that particulate matters of different granulations are one of the most important air and environmental pollutants, in general. This paper presents a prototype system for filtering particulate matter from extinguishing gases of a bitumen preparation plant using a "jet pulse" method for filter bags cleaning. For such type of filter plant, due to technological reasons, there is the need to create a shock wave which is required for the cleaning of the filter bags. The shock wave is generated by electromagnetic valves, whereas the tactile of the valve is determined by special controller depending on the type of filter, bags and air pollution. The result obtained through the use of special types of controllers allows the life span of the electric fan and the prevention of their overheating and damage.
