The operation temperature of the application of central dust collector should be considered according to the long-term operation temperature. In order to avoid condensation, the flue gas temperature of the application of central dust collector should be kept 15 ~ 20℃ higher than the dew point. When purifying the high temperature gas whose temperature is close to the dew point, the relative humidity of the gas should be reduced by indirect heating or mixing with high temperature gas.
When running the application of central dust collector, you should observe the status of the differential pressure system to check for faults. The pressure difference value of the pressure difference system in the application of central dust collector should be accurately recorded. If the pressure difference is suddenly found in the recording process, the filter bag should be checked to see whether there is blockage or dust compaction. At the same time, the cleaning system should be accurately checked to avoid excessive ash accumulation in the ash hopper. If there is a sudden drop in the recording process, it may be that the filter bag is damaged or falling off.
Here is how to improve the application of central dust collector:
In the application of central dust collector, it is necessary to prevent the gas from cooling below the dew point in the bag room, especially in the application of central dust collector equipment under negative pressure.
Second, because the shell often has air leakage, so that the gas temperature in the bag room is lower than the dew point, the filter bag will be damp, resulting in dust is not loose, but sticky attached to the filter bag, the fabric hole is blocked, resulting in dust removal failure, so that the dust collector pressure drop is too large, can not continue to run, some paste bag can not dust.
A chamber lifting valve is closed, the filter air is cut off, and then the electromagnetic pulse valve is opened, the compressed air expands in the upper box in a short time, and rushes into the filter bag, so that the filter bag expands and deforms to produce vibration, and under the action of reverse airflow scour, Dust attached to the outer surface of the filter bag is stripped and dropped into the ash hopper.
Four, after the completion of cleaning, the electromagnetic pulse valve is closed, the lifting valve is opened, and the chamber is restored to the filtering state. Cleaning each room in turn, from the beginning of room cleaning to the next cleaning for a cleaning cycle. After filtration and dust removal work is intercepted into the ash hopper, and then by the ash hopper mouth of the ash discharge device.
With the extension of filtration time, the dust layer on the filter bag continues to accumulate thick, and the resistance of the dust removal equipment continues to rise. When the resistance of the equipment rises to the set value, the cleaning device begins to clean the dust.
The equipment that separates dust from flue gas is called dust collector or dust collector. The performance of the dust collector is expressed in terms of the amount of gas that can be processed, the resistance loss of gas passing through the dust collector and the dust removal rate.
Seven, the price of dust collector, operation and maintenance costs, good and short service life and the difficulty of operation management are also important factors to consider its performance. Dust collector is a common facility in boiler and industrial production.
