Esp Wet Electrostatic Precipitator For Boiler Flue Gas Desulfurization

Product Description

The wet electrostatic precipitator uses the method of electrostatic precipitator to separate the aerosol and suspended dust particles in the gas. It mainly includes the following four complex and interrelated physical processes:
(1) Ionization of gas. Dust Collector Equipment.
(2) Condensation and charging of aerosols and suspended dust particles.
(3) The charged dust particles and aerosol move to the electrode.
(4) The water film makes the electrode plate clean.
Tens of thousands of volts of DC high voltage is applied between the anode and cathode wires of the wet electrostatic precipitator. Under the action of a strong electric field, a corona layer is generated around the corona wire, and the air in the corona layer undergoes avalanche ionization, thereby producing A large number of negative ions and a small amount of positive ions, this process is called corona discharge; the dust (fog) particles that enter the wet electrostatic precipitator with the flue gas collide with these positive and negative ions to be charged, and the charged dust (fog) Due to the Coulomb force of the high-voltage electrostatic field, the particles move toward the anode; after reaching the anode, the charge is released, and the dust (fog) particles are collected by the anode, and the dust is collected to form a water film, which is self-cleaning by gravity or washing. It flows up to the lower liquid accumulation tank or absorption tower, and is separated from the flue gas.
Working principle

When the gas containing tar droplets and other impurities passes through the electric field, the impurities of negative ions and electrons are adsorbed, under the action of coulomb force of electric field, and then the charge is released after moving to precipitating pole, and adsorbed on the precipitating pole, so as to achieve the purpose of purifying the gas, which commonly known as the charge phenomenon. When the impurity mass adsorbed on the precipitating pole increases to greater than its adhesion, it will automatically flow down and discharge from the bottom of electric tar catcher, and the net gas will leave from the upper part of electric tar catcher and enter into the next process，ESP dust collector.
