    The working principle of the electrostatic precipitator is to use high specific resistance to evaluate the conductivity, which has a direct impact on the dust removal efficiency. The specific resistance is too low for the dust particles to be held on the dust collection electrode, causing them to return to the gas stream. The specific resistance of the electrostatic precipitator is too high, and the dust particle charge that reaches the dust collection electrode is not easy to be released, and the piezoelectric field in the dust layer ionizes the flue gas, and the dust charge in the gas flow is separated from the air flow under the action of the electric field.

    The negative electrode of the electrostatic precipitator is made of metal wires with different cross-sectional shapes, which is called a discharge electrode. The positive electrode is made of metal plates of different geometries and is called a dust collector electrode. The performance of the electrostatic precipitator is affected by three factors: dust properties, equipment construction and flue gas velocity.

    The formation of voltage gradients between the electrostatic precipitator dust can produce local breakdown and discharge phenomena. All of these conditions can lead to a decrease in dust collection efficiency.

    The electrostatic precipitator is a device that collects dust in flue gas by electrostatic purification method. It is an ideal equipment for purifying industrial exhaust gases. Its purification work mainly relies on two systems: the discharge electrode and the precipitating electrode.

    When high-voltage direct current is input between the two poles, anions and cations are generated in the electrode space, and act on the surface of the exhaust gas particles passing through the electrostatic field, move to the electrodes of opposite polarity under the action of the electric field force, and deposit them on the electrodes to achieve the purpose of dust collection. The two-pole system has a rapping device, when the hammer hits the two-pole device periodically, the dust adhered to it is shaken off and falls into the lower ash hopper and discharged out of the machine through the ash discharge device. The purified exhaust gas is discharged into the atmosphere through the chimney from the outlet, and the flue gas purification process is completed at this time.

    The working principle of electrostatic precipitator is electrostatic precipitator.

    Air purifiers utilize high-voltage direct current.

    The field ionizes the gas molecules in the air, producing a large number of electrons and ions in the electric field.

    Under the action of moving to the poles, in the process of moving, the dust particles and bacteria in the air flow are charged to make them charged, and the charged particles move to the plates with opposite charges under the action of the electric field force, and under the action of the electric field, the free ions in the air should move to the poles, the higher the voltage and the strength of the electric field.

    The higher it is, the faster the ion moves.

    Electrostatic precipitators. When the flue gas passes through the flue in front of the main structure of the electrostatic precipitator, the smoke and dust are positively charged.

    The flue gas then enters the electrostatic precipitator channel, where a multi-layer cathode plate is set.

    The electrostatic precipitator is composed of two parts: one is the electrostatic precipitator body system; The other part is the power supply device and the low-voltage automatic control system that provide high-voltage direct current.

    The high-voltage power supply system supplies power to the step-up transformer, and the dust collector of the dust collector is grounded. The low-voltage electric control system is used to control the temperature of the electromagnetic hammer, ash discharge electrode, ash transfer electrode and several components.

The principle of electrostatic precipitator: according to the principle of "opposites attract, similarities repel", after the gas is ionized, a large number of free electrons and positive and negative ions will move to the opposite pole. In the process of movement, they collide with the dust particles in the flue gas stream and adsorb on them, so that the dust particles are charged, which is the dust particle charge. >>>More
