As we know, wet electrostatic precipitator is called wet electric for short. Its main working principle is the same as that of dry electrostatic precipitator. It absorbs dust and fine particles through high-voltage electrostatic electricity. So what is the difference between them?

The difference between a wet dust collector and a dry dust collector is dust removal. When a dust collector works, dust builds up on the surface of the material and needs to be cleaned. This is called dust removal.

Let's start with dry dust collectors. Dry dust collector uses vibration to clean the dust, constantly clean the dust deposited on the surface of the material, and keep the surface of the material clean to meet the customer's requirements.

There are many methods of dry dust removal, such as mechanical vibration, brush cleaning, electromagnetic vibration, capacitance vibration, air excitation cleaning and so on. At present, air excitation is the more widely used method in dry ESP. The air excitation device includes fan, integrated box, pipeline, etc. The excitation effect depends on the strength and speed of the fan. The excitation effect depends on the strength and speed of the fan. The use of air excitation to clear dust does not easily lead to the increase of secondary dust and equipment damage.

In addition to ordinary air excitation, dry dust collectors have ultrasonic dust removal. The acoustic generator turns the compressed air into strong acoustic waves, which enter the dry dust collector to spread in all aspects. It takes the dust as mechanical energy to form a high-speed periodic oscillation, which counteracts the surface adhesion of the dust, prevents the dust from combining into a hard shell, and at the same time loosens the agglomerated layer of dust to fall off from the pole plate, thus achieving the effect of acoustic wave dust removal.

Wet dust removal in the use of spraying method of clearing dust, water to clean the pole plate, the formation of a layer of water film on the surface of the pole plate, which is conducive to the dust brought to the equipment, to achieve the purpose of clearing dust.

Each type of environmental protection equipment has its advantages and disadvantages, wet dust collector and dry dust collector is the difference between the ash removal method, relative to the wet dust collector, dry dust does not touch the surface of the material, the material does not produce secondary damage, and easy to install, smaller, has been in the lithium, film, printing and packaging and so on the cleanliness of the material requirements of the enterprise to use a relatively high degree.
