What is an Electrostatic Precipitator?
Electrostatic Precipitator is a gas dust removal method. It is a dedusting method that uses electrostatic field to ionize gas, so that dust particles are charged and adsorbed on electrodes. In the strong electric field, the air molecules are ionized into positive ions and electrons, and the electrons encounter dust particles in the process of running to the positive electrode, so that the dust particles are negatively charged and adsorbed to the positive electrode for collection. It is commonly used in coal-fueled factories and power plants to collect ash and dust from flue gases. It is also used in household dust removal and sterilization products.
The electrostatic precipitator developed by AIRDOW is used in the air purifier, and the sterilization rate of the air purifier is obvious.
How does an AIRDOW electrostatic precipitator work ?
An electrostatic precipitator, is a filtration device that removes fine particles, like smoke and dust, from a flowing gas using the force of an induced electrostatic charge, minimally impeding the flow of gases ,through the unit.
First, The polluted air first flows through an ionization section that is charged to a voltage of 8000 Volt. This gives a positive charge to the pollutants.
Second, The air passes the collector section that collects the pollutants. To make the collector work, high voltage of 4000 Volt is applied to each alternate plate and the intervening plates are grounded so there is a high voltage difference between the plates. The charged pollutants are attracted to and deposited on the grounded plates.
The pre-filter helps to remove big particulates and maintain the performance of inner filter, while the activated carbon filter helps to control the odor.
NOTE : The ESP filter needs to be cleaned at regular intervals such that a good performance can be guaranteed . There is no replacement cost ever with a high efficiency.
