Pulse Jet Bag Filter

Pulse bag filter, as an efficient dry industrial filtration device, is particularly suited for capturing fine, dry, and non-fibrous dust particles. Its filter bags are crafted from selected textile filter cloth or non-woven felt, utilizing the precise filtration capabilities of the fiber fabric to effectively filter out dusty gases and ensure the purification of flue gas. The dust collector employs industry-leading online pulse jet cleaning technology, which ensures thorough cleaning and offers extremely low operational resistance. Furthermore, the high-quality components guarantee efficient and stable dust removal performance. Additionally, the dust collector is fully automated, providing not only high operational efficiency but also extremely convenient maintenance and repair. With its outstanding purification efficiency, long service life of filter bags, minimal maintenance requirements, and safe, reliable operation, the pulse bag filter has become the ideal choice for dispersed dust emission points such as machine tops and bottoms, and is widely applied in the dust purification of various crushing and screening equipment.

The pulse bag filter mainly consists of the following components:

(1) Box Assembly: Including the bag house, pre-dust chamber, clean air chamber, perforated plate, filter bags, filter bag frames, and inspection door. The box assembly is designed to withstand a pressure of 5000Pa.

(2) Exhaust System: Comprising the fan and its matched motor.

(3) Pulse Jet System: Consisting of the main air duct, blowing pipe, pulse valves, and control device.

(4) Inlet and Dust Discharge Mechanism: Offered in two configurations: one with a standard dust hopper, and the other with an open flange design.

Dusty gas either surges into the dust hopper through the inlet or enters the filter bag chamber via the open flange. In the chamber, the dusty gas is transformed into pure gas that flows into the clean air chamber. Subsequently, this clean gas is discharged through the exhaust port of the clean air chamber, driven by the fan.

Over time, dust gradually accumulates on the outer surface of the filter bags, layer by layer, causing the resistance of the bag filter to steadily rise. To ensure that the resistance of the equipment remains below 1200Pa, ensuring efficient operation of the bag filter, it is necessary to regularly remove the dust from the filter bags.

The dust cleaning process is carefully controlled by a program controller, which activates the pulse valves in a timed sequence. This allows compressed air (with a pressure between 0.5 and 0.7 MPa) stored in the tank to be ejected through the holes in the blowing pipe (known as the primary air). Guided by the Venturi tube, the primary air cleverly induces several times its volume of surrounding air (known as the secondary air) to enter the filter bags together. Inside the filter bags, this mixed airflow instantly expands rapidly, and with the reverse action of the airflow, the dust on the filter bags is abruptly shaken off, achieving the purpose of dust cleaning.

1.High efficiency of ≥ 99.5%.

2.Low emission concentration of ≤ 20um, and can be reduced to ≤ 10um after filtering depending on actual conditions.

3.Low leakage rate.

4.Material: Carbon steel or stainless steel.

5.Simple structure, easy maintenance.

6.Suitable bags and bag cages are installed based on the characteristics of the dust. Options include glass fiber, needle felt, PTFE, p84, etc.

7.When the system fan and system are operating normally, maintenance and bag replacement can be performed on individual compartments.

8.The entire equipment adopts PLC control, enabling automatic dust removal and collection, automatic temperature control, and over-temperature alarm.

9.It is insensitive to the characteristics of the dust and is not affected by dust or resistance.
