What is the principle of electrostatic precipitator? What is the principle of an electrostatic preci

Principle: Dusty gases pass through a high-voltage electrostatic field.

When electronically separated, dust particles are separated from negative ions.

After the binding belt is negatively charged, it tends to discharge on the surface of the anode and is deposited.

Under the action of the electric field, the free ions in the air have to move to the poles, the higher the voltage and the strength of the electric field.

The higher it is, the faster the ion moves. Due to the movement of the ions, an electric current is formed between the poles.

In the beginning, there are fewer free ions in the air and less current. When the voltage rises to a certain value, the ions near the discharge electrode gain higher energy and velocity, and when they hit the neutral atom in the air, the neutral atom will break down into positive and negative ions.

As a result of the chain reaction, the number of ions moving between the poles is greatly increased, and the high voltage traps the attached bacterial particles, instantaneously conductive to break down the cell wall composed of proteins.

Achieve bacterial adsorption and dust removal.

The working principle of the electrostatic precipitator is to use a high-voltage electric field to electrically separate the dust in the air. Specifically, the electrostatic precipitator is equipped with a charged collection plate and a discharge coil inside, and when air passes through these devices, the charged collection plate attracts the charged dust, separating it from the air and depositing it on the collection plate. At the same time, the discharge coil generates a high-voltage electric field that attracts the positively charged dust in the air that is not collected by the electric field and forms an ionic region on the collection plate, which is eventually collected.

This removes dust from the air and purifies the air. Electrostatic precipitator is a kind of efficient air purification equipment, which is often used in industrial production, medical and health, aerospace and other fields.

The working principle of the electrostatic precipitator: When the dust-containing gas passes by, the electrostatic precipitator will produce a corona discharge, so that the dust-containing gas will have a positive charge. Then under the action of the electric field force, the positively charged dusty gas is adsorbed on the cathode plate.

By striking the cathode plate at regular intervals, the dusty gas can be dropped into the ash hopper under the electrostatic precipitator, thus removing the dust. The main structure of the electrostatic precipitator is a steel structure, all of which are welded by section steel, and its outer surface is skin and insulation material.

The basic principle of the electrostatic precipitator is to use electricity to replenish the dust in the flue gas, which mainly includes the following four interrelated physical processes, the ionization of gases, the ionization of dust, nuclear power nuclear power, the electrode of dust moving nuclear power, the capture of dust, nuclear power, the capture process of dust, on the metal anode and cathode with a large difference in radius between the two regions, through high-voltage direct current, it is enough to maintain a sufficient to ionize the gas, power plant, electrons, anions and cations generated after the ionization of gas, on the dust through the electric field, The dust acquires an electric charge, and the dust with different electrodes moves to the electrodes of different polarities under the action of the electric field force and is deposited on the electrodes to achieve the purpose of dust and gas separation.

The electrostatic precipitator uses a strong electric field to ionize the gas, that is, to produce a corona discharge, which then charges the dust and forces in the electric field.

Under the effect, the dust is separated from the gas of the dust removal device.

The separation of suspended dust particles in gas by the method of electrostatic precipitator mainly includes the following complex and interrelated physical processes: the application of high voltage and the generation of strong field strength.

ionization of gases and corona discharge; Charge of suspended dust particles; Charged dust particles move towards the electrodes under the action of electric field forces; Charged dust particles are collected in an electric field; Vibrating and cleaning the ashes.

The working principle of the electrostatic precipitator is to use a high-voltage electrostatic field to capture dust according to the chargeability of the dust.

The working principle of electrostatic precipitator electrostatic precipitator uses high-voltage direct current electric field to ionize gas molecules in the air, producing a large number of electrons and ions, moving to the poles under the action of electric field force, and encountering dust particles and bacteria in the air flow to make them charged during the movement process, and the charged particles move to the plates with opposite charges under the action of the electric field force, under the action of the electric field, the free ions in the air should move to the poles, the higher the voltage, the higher the electric field strength, and the faster the movement speed of the ions.

When the flue gas passes through the flue gas in front of the main structure of the electrostatic precipitator, the smoke and dust are positively charged, and then the flue gas enters the electrostatic precipitator channel with multi-layer cathode plates.

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 electrostatic precipitator is a dust removal device that uses a strong electric field to ionize the gas, that is, to produce corona discharge, which then charges the dust and separates the dust from the gas under the action of the electric field force.

The separation of suspended dust particles in gas by the method of electroprecipitator mainly includes the following complex and interrelated physical processes: the application of high voltage, the generation of strong field strength, the ionization of gas, and the generation of corona discharge; Charge of suspended dust particles; Charged dust particles move towards the electrodes under the action of electric field forces; Charged dust particles are collected in an electric field; Vibrating and cleaning the ashes.

The electrostatic precipitator is a kind of flue gas purification equipment, its working principle is: when the dust particles in the flue gas pass through the high-voltage electrostatic field, the positive and negative ions and electrons between the electrodes collide and are charged (or charged in the ion diffusion movement), the dust particles with electrons and ions move to the heterosexual electrode under the action of the electric field force and accumulate on the heterosexual electrode, and the dust on the electrode falls into the collecting ash hopper through vibration and other means, so that the flue gas through the electrostatic precipitator can be purified, so as to achieve the purpose of protecting the atmosphere and protecting the environment.

The basic structure of the electrostatic precipitator is as follows:

1. Intake smoke box 8, rapping and transmission system 2, outlet smoke box 9, groove plate system 3, shell, ash system 4, cathode system 12, stair platform 5, anode system 13, high and low voltage power supply system 6, cathode frame 14, household shell and insulation layer 7, anode frame 15, cathode corona wire The whole power supply process is simply 380V power supply sent to the primary winding of the rectifier transformer, and one end of the two terminals of the secondary winding is connected to the anode plate (the anode plate is grounded), The other end is connected with the cathode electrode line in the electric field through the damping resistance, so that a strong electrostatic electric field can be formed between the cathode and anode electrode plates and the pole line when energized, which can adsorb the dust particles in the flue gas, and the clean flue gas is sent to the chimney through the induced draft fan to be discharged into the atmosphere to achieve the effect of dust removal. The control of the secondary voltage of the whole dust collector is realized by the primary voltage, that is to say, the primary line voltage is 380V, and the size of the conduction angle of the thyristor can be changed through the controller, which can change the size of the primary voltage, and then indirectly change the size of the secondary output voltage of the rectifier transformer, and the rectifier circuit is composed of many rectifier diodes or silicon stacks inside the rectifier transformer, and its function is to rectify the AC power supply input into DC power supply input into the electric field after stepping up. A strong electromagnetic field is formed inside the electric field to adsorb dust particles and achieve the effect of dust removal.

Electrostatic precipitator is a gas precipitator method, that is, electrostatic precipitator, and this electrostatic electricity is high voltage. Relies on positive and negative ions to neutralize ions on dust. When the dust-containing gas passes through the high-voltage electrostatic field, it is electroelectrically separated, and the dust particles are combined with negative ions to carry negative electricity, and tend to discharge on the surface of the anode and be deposited.

The working principle of the electrostatic precipitator is that the dust passes through the area with a high-voltage power supply, and under the force of the electric field, the dust is transported from the pole line to the grade plate and attached to the grade plate.
