Introduction to the difference between cyclone dust collector and bag dust collector
Cyclone dust collector, also known as cyclone separator, is widely used in convective drying and drying system. It is the main dust removal equipment to collect products from gas. The cyclone dust collector has the advantages of simple structure and convenient manufacture. As long as it is properly manufactured, it can obtain high separation efficiency.
For the gas with high dust content, it can also be separated directly, and the pressure loss is relatively small, so there are no moving parts. There is no adhesion or wear to the inner wall of the cyclone separator except for grinding fine powder.
In theory, the cyclone separator can capture 5 μ M above, the separation efficiency can reach more than 90%. However, in the actual production and operation, the separation efficiency is often reduced due to poor manufacturing, improper installation and use or imperfect operation management. Generally only 50% ~ 80%, sometimes even low. Dust collector equipment
Bag filter (bag filter or bag filter) is often used as a gas-solid separation equipment to separate powdery products from dry tail gas. It is a line of defense to intercept the powder in tail gas. Bag filter is characterized by capture. It can be said that among many gas-solid separation equipment, its capture efficiency is inferior to that of other equipment, especially 20 μ When the particles below m increase obviously, the efficiency reaches more than.
The bag filter is mainly composed of filter bag, bag frame and shell. The shell is composed of box and air purification chamber. The bag is installed on the partition between the box and air purification chamber. After the dusty gas enters the box, the powder will produce inertia, diffusion, adhesion and electrostatic effects and adhere to the surface of the filter cloth. The clean gas will be discharged from the air purification chamber through the pores of the filter cloth. The dust on the filter cloth will separate from the filter cloth and fall into the hopper through back blowing or vibration.
