Structural characteristics of coal-fired boiler dust collector

The coal-fired boiler dust collector is an external filter type dust collector, which means that the dust containing gas is outside the filter bag, the clean air is inside the filter bag, and the bag opening is upward. Start the pulse blowing valve during dust cleaning to radially deform the filter bag and shake off the dust. This dust collector has the characteristics of dust removal (dust removal efficiency exceeding), simple structure, and offline maintenance.

1. The dust collector of the coal-fired boiler adopts the technology of segmented air stop pulse blowing for dust cleaning, which overcomes the shortcomings of conventional pulse dust collectors and segmented back blowing dust collectors. It has 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 box adopts an airtight design with good sealing performance. The inspection door uses excellent sealing materials, and during the manufacturing process, kerosene is used for leak detection, resulting in a very low air leakage rate.

Boiler dust collector is a commonly used supporting equipment in boilers and industrial production. Its function is to add particulate smoke and dust from boiler fuel and combustion emissions, thereby significantly reducing the amount of smoke and dust emitted into the atmosphere. This is an important environmental protection equipment for environmental pollution and improving air quality
