KWD Wide-Pitch Electrostatic Precipitator
KWD Wide Pitch Electric Dust Collector @ KWD Wide Pitch Electric Dust Collector Manufacturer @ KWD Wide Pitch Electric Dust Collector Supplier
KWD wide-spaced electrostatic precipitator uses high-voltage direct current to charge the dust particles in the dust-containing gas. Under the action of electric field force, it is deposited on the surface of the settling electrode, and it is made into a sheet by the action of vibration Dust has fallen into the device. KWD wide-spaced electrostatic precipitator is used to purify the flue gas from the electric precipitator and meet environmental protection emission standards. It is an ideal equipment for the purification of industrial waste gas such as thermal power generation, metallurgy and non-ferrous metals.
Installation of KWD Wide-Pitch Electrostatic Precipitator:
1. The size of the civil foundation should be checked before the installation of the equipment. If there is any discrepancy, it should be handled. Install the support on the foundation table and level it with a spirit level.
2. Inventory and check according to the equipment list. Correct any parts that have been deformed due to lifting or long-term storage before installation. Sampling inspection of main parts (such as electrode plate, corona wire corona electrode frame), manufacturing deviation should be corrected if it exceeds the design requirements, if it cannot be corrected, it should be scrapped.
3. All parts of the discharge electrode and precipitation electrode system are coated with special paint at the manufacturer. If not available, they can be replaced with kerosene and carbon black seasoning.
4. The cleaning and refueling of transmission components shall be carried out with reference to the specifications for the installation and construction and acceptance of machinery and equipment.
KWD Wide-Pitch Electrostatic Precipitator Selection
Electric field strength
The pole distance has no obvious influence on the electric field strength, generally 3 ~ 3.5kV / cm, and the rated voltage of the equipment can be slightly higher than this value.
Corona line spacing is related to the shape of the corona electrode. For ordinary round or star wires, the line spacing is 0.5 to 0.8 for the pole pitch. For thorn lines, the line spacing is about the same as the pole pitch.
For dust collectors larger than 100m2, the plate distance should be 500 ~ 600mm. For dust collectors smaller than 100m2, the pole distance is 400 ~ 500mm, the former is 90 ~ 120kV and the latter is 72 ~ 90kV. The pole-type electrostatic precipitator and the riser-type electrostatic precipitator have a pole distance of 1000mm and a power supply voltage of 150kV.
4. Corona current
Corona current is closely related to smoke and dust properties and humidity. Under the same working conditions, the corona current is proportional to the pole distance, such as the pole distance is 250mm, the specific current of the corona electrode is 0.22mA / m; When the distance is 500mm, the specific current can be selected as 0.44mA / m.
Features of KWD Wide-Pitch Electrostatic Precipitator
1. Reduce power consumption. Although the current of the corona electrode line of the KWD wide-spaced electrostatic precipitator increases, the number of corona electrodes decreases, so the total current decreases and the total power also decreases.
2. Can effectively capture high specific resistance soot. The wide-spaced anti-corona phenomenon is reduced. At the same time, due to the high speed of the electric wind near the corona wire, the smoke and dust are not easy to stick together, and the electricity is not easy to generate the corona blocking phenomenon.
3. Save investment. As the pole distance is increased, the number of corona electrodes is reduced, and the weight of the dust collector is reduced. However, for a pole distance of 400 ~ 500mm, the cost of increasing the voltage is very small or no need to increase the cost.
4. Easy to repair and install. Generally, the installation error of the electrostatic precipitator is extremely strict. The installation error of the electrostatic precipitator with a pole distance of 400 ~ 500mm can be slightly relaxed, and the wide-pole distance electrostatic precipitator is easy to change the corona wire.
5. Capable of trapping ultra-fine soot (0.01um). KWD wide-spaced electrostatic precipitator can increase the operating voltage, accelerate the aggregation of ultra-fine soot, increase the particle size of soot, increase the speed of soot drive, and facilitate the collection of ultra-fine soot.
Dust removal mechanism of KWD wide-spaced electrostatic precipitator :
The wide-spaced electrostatic precipitator is a device for capturing dust in flue gas by electrostatic purification method. Its net profitability mainly depends on two systems: discharge electrode and precipitation electrode. When high voltage direct current is input between the two electrodes, anion and cation are generated in the electrode space, and they act on the surface of the exhaust dust particles passing through the electrostatic field. They are moved to the electrode of opposite polarity by the force of the electric field and are deposited on the electrode to The purpose of dust collection. Both pole systems have vibrating devices. When the vibrating hammer type periodically strikes the two pole devices, the dust adhered to it is shaken off and falls into the lower ash bucket and is discharged out of the machine through the ash discharging device. The purified exhaust gas is discharged into the atmosphere from the outlet through the chimney, and the purification process of the flue gas is completed at this time.
