The DMC single machine bag filter consists of an ash hopper, an upper box, a middle box, a lower box, and other parts. The upper, middle, and lower boxes are divided into compartments. During operation, dusty gas enters the ash hopper through the air inlet duct. Coarse dust particles directly fall into the bottom of the ash hopper, while fine dust particles enter the middle and lower boxes upwards with the turning of the airflow. Dust accumulates on the outer surface of the filter bag, and the filtered gas enters the upper box to the clean gas collection pipe exhaust duct, and is discharged to the atmosphere through the exhaust fan. The dust cleaning process involves first cutting off the clean air outlet duct of the room, so that the bag in the room is in a state of no airflow passing through (stopping the air and cleaning the dust in each room). Then, the pulse valve is opened and compressed air is used for pulse blowing to clean the dust. The shut-off valve is closed for a sufficient time for the dust peeled off from the filter bag to settle in the ash hopper after spraying, avoiding the phenomenon of dust adhering to the adjacent filter bag surface with the airflow after leaving the filter bag surface. The filter bag is cleaned, and the exhaust valve, pulse valve, and ash discharge valve are fully automatically controlled by a programmable pulse controller.

characteristic

1. The DMC single machine bag filter adopts the technology of pulse jet dust cleaning with air stop in each compartment, overcoming the shortcomings of conventional pulse dust collectors and back blowing dust collectors in each compartment. It has strong dust cleaning ability, low emission concentration, low air leakage rate, low energy consumption, low steel consumption, small footprint, stable operation, and good economic benefits. Suitable for the purification of dusty gases and material recovery in metallurgy, building materials, cement, machinery, chemical, power, and light industry industries.

2. Due to the use of segmented air stop pulse spraying for dust cleaning, the cleaning cycle is extended and the energy consumption for dust cleaning is reduced, resulting in a significant decrease in compressed air consumption. At the same time, the fatigue level of the filter bag and pulse valve is correspondingly reduced, thereby doubling the service life of the filter bag and valve plate.

3. The maintenance and bag replacement can be carried out in separate rooms without stopping the system fan and under normal operating conditions of the system. The filter bag mouth adopts an elastic expansion ring, which has good sealing performance and is firm. The filter bag keel adopts a polygonal shape, which reduces the friction between the bag and the keel, extends the life of the bag, and is easy to unload.

4. Adopting the upper bag extraction method, after extracting the skeleton during bag replacement, the dirty bag is put into the lower ash hopper of the box and removed from the manhole, which meets the operating conditions for bag replacement.

5. The DMC single machine bag filter box adopts an airtight design with good sealing performance. The inspection door is made of excellent sealing materials, and during the manufacturing process, kerosene is used for leak detection, resulting in a very low air leakage rate.

6. The layout of the inlet and outlet air ducts is compact, with low airflow resistance.
