ZM Series Bag Filter Widely Used Cement Plant/Highly Efficient Dust Collection Equipment
Basic Structure of Bag Filter:
The basic structure of the bag filter is divided into three parts:
1. The main body of the dust collector is composed of air inlet chamber, bag chamber and ash hopper;
2. Filter bag part;
3. Auxiliary equipment: ash cleaning mechanism and ash discharge device.
Types of Bag Filter:
There are many forms and types of bag filters, so they are usually classified according to their different characteristics.

According to the Cleaning Method:
1 Mechanical vibration cleaning
Mechanical rapping for dust removal, including artificial rapping, mechanical rapping and high frequency oscillation, etc. This is one of the oldest and simplest methods, once widely used in industry. However, due to the uneven distribution of mechanical rapping, the required filter wind speed is low, and the damage to the filter bag is great. Recently, it has been gradually replaced by other cleaning methods.
2 Airflow blows back and cleans dust
Airflow reverse blowing and dust removal is to use outdoor or circulating air (with a certain pressure) to pass through the filter bag in the opposite direction to the dust-containing airflow to make the dust particles fall off. In this kind of dust removal method, on the one hand, the dust removal airflow in the opposite direction directly impacts the dust; on the other hand, due to the change of the airflow direction, the filter bag produces expansion and contraction vibration, which causes the dust to fall.
The airflow back-blowing cleaning dust is relatively evenly distributed on the entire filter bag, but the cleaning intensity is small, and the filtering wind speed should not be too high. Usually, the air stop is used to remove the dust.
ZM Series Bag Filter Working Principle:
Dust Collector is composed of supporting structure, dust bucket, middle box, upper box, filter bag, frame, injection and clean device, PLC control system. Middle box has many compartments, and the air content dust will be injected to each dust hopper at working. The big size dust will drop in the bottom of the bucket due to lower air speed and impact by bucket. The final size dust will float to each bags, separate outside bags, then drop to the bottom hopper, and cleaned air will be released through exhaust pipe.
