Boiler dust collection series-coal-fired boiler bag dust collector

The coal-fired boiler dust collector is suitable for flue gas dust removal and desulfurization of coal-fired, oil-fired boilers and kilns. It has the characteristics of low resistance, flexible installation and layout, high desulfurization efficiency and long service life!

2. Working principle:

The coal-fired boiler dust collector is composed of an ash hopper, an upper box body, a middle box body, a cloth bag, and a dust cleaning and blowing device.

Treatment flue gas volume: 3000-600000m3 / h, desulfurization efficiency can reach more than 85%.

When working, the high-temperature flue gas flows into the ash hopper from the air inlet on the ash hopper. Due to the gravity sedimentation, the coarse dust particles directly fall into the bottom of the ash hopper, which plays the role of pre-dust collection. Going upward into the middle box, the dust is filtered and retained by the high-temperature filter bag and accumulated on the outer surface of the filter bag. The filtered gas enters the upper box to the air outlet through the filter bag, and is discharged to the atmosphere through the induced draft fan. The dust accumulated on the outer wall of the filter bag continues to increase. When the set time is reached, the pulse controller sequentially triggers to open the pulse solenoid valve, so that the compressed air in the compressed air bag pulse sprays the dust from each row of filter bags through the blowing pipe. In order to make the filter bag expand rapidly and shake off the dust accumulated on the outer wall of the filter bag, the dust peeled from the filter bag settles into the ash hopper and is discharged through the ash discharge gate valve.
