Details

The smoke produced during the burning of any fuel contains charged particles. When these charged particles are passed through a charged capacitor, they get attracted towards the plates of the capacitor. Such a device is called electrostatic precipitator. The filter described in this project acts as an electrostatic precipitator. When high voltage is applied on the Aluminium foil and a wire hanging at the center of the glass tube, it acts as a precipitator. All the charged particles of smoke stick to the walls of the filter and so smoke pollution is prevented. Construction of Smoke filter Material Required 1. I mt long glass tube / any insulator (one end narrow. diameter 1/2") 2. This Aluminium foil - 4" wide (As a capacitor) 3. One - Induction coil (for high voltage output) 4 One kerosene lamp 5. One-Iron funnel 6. One - Two holed stopper 7. Two - 1.5 volt batteries 8. One - Switch 9. 3/4 mts long conductor (thick metal wire) 10. One- delivery tube. 11. One - rubber holder. Method of Construction 1. Wrap the aluminium foil around the glass tube near the narrow end of the tube. The alumunium foil acts as the cathode and as well as a capacitor. 2. Close the wide end of the glass tube with the two holed stopper. 3. Hang one thick metal wire down the center of the tube through the stopper such that it does not touch the walls of the tube. This forms the cathode. 4. Through the other hole insert a delivery tube. 5. Below the narrow end opening. Fit the funnel with the help of the rubber holder. Working 1. Place the burning kerosene lamp below the funnel such that the smoke enters into the funnel. 2. Switch on the induction coil in the circuit. In this case, the positive carbon particles are attracted by the negatively charged aluminium plate. 3. Carbon particles settle down and pure air comes out of the delivery tube. 4.The smoke coming out of the silencer or chimney can be filtered to remove carbon particles, thus the smoke filter helps to avoid air pollution.

Benefits

This can be suitably modified and used along with the silencer to filter the carbon particle from smoke.
