Pollution


Detail:

This is an accessory that is attached to the genset. It precipitates the particles of the flue gases, lowers their temperature and also dampens the noise considerably. The attachment consists of a cylindrical drum having concentric perforated screens and a few long perforated tubes having equally spaced mesh linings. Fins have been provided on the internal surface of the cylinder for breaking the sound waves. The cylindrical drum, weighing 65 kg, is placed between the generator and the exhaust pipe. The exhaust gases, which enter the unit, strike against the array of protruding fins and perforated tubes continuously. The vortex results in the dissociation of CO and CO2 into carbon particulates and oxygen. The innovation also works as a silencer by internally canceling out sound waves as they pass through a series of concentric channels. The geometry and construction of the unit also delivers removal of carbon-based effluents as soot and solid deposits. The exhaust gases, which come out eventually are very clean and leave no trace of carbon on the leaves of the tree growing nearby. The unit functions as an attachment, not only for precipitating carbon particulates from the flue gas and damping the sound, it also reduces the temperature. On an average, after 3000 hours of engine operation, the innovator removes about 5 kg of soot using the chute at the bottom of the drum. In about six to eight months, it collects 12 to 14 kg of carbon, which can be easily taken out from the opening at the bottom. The innovativeness of the machine lies in its design and construction. The variation in geometries, zonal volumes and pipe segments create “area discontinuities” which act as an impedance mismatch for the sound waves to travel further. Secondly, there are the multiple reflections of sound waves internally, which cancels them out. Testing of the device was done with 5 BHP Kirloskar engine under different loads in BIT Mesra, Ranchi where reduction in CO and CO2 up to 30 % and considerable reduction in temperature was observed. NIF has filed a patent (1520/KOL/2008) in the name of Virendra Kumar Sinha for this innovation.
