Electrostatic precipitator is highly efficient filtration device which allows the flow of gases. This device can easily remove the fine particulate matter like dust and smoke from air stream that is present in industrial and thermal power exhausts using force of an induced electrostatic attraction like charges repel or unlike charges attract. Electrostatic precipitator have charged plates which are connected with the ground. The electrode wires are provided with high volts electric current. These small particles present in dirty air are firstly charged electrically and then allowed to settle down over differently charged scrubbers.
Working:- This device contains electrode wires which are maintained at high volts which releases electrons. These electrons then attach to dust particles that gives them net negative charge. The collecting plates are present on the ground level and they attract the dust particles.
