dust extractor pleated filter cartridges operating temperature should be considered according to long-term operating temperature, in order to avoid condensation, Generally, keep the smoke temperature of dust extractor pleated filter cartridges 15 to 20 ° C 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 dust extractor pleated filter cartridges, you should observe the status of the differential pressure system and check whether the differential pressure system has a fault. The dust extractor pleated filter cartridges has accurately recorded the pressure difference value of the pressure difference system. If the pressure difference has suddenly occurred during the recording process, you need to check the filter bag 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 dust extractor pleated filter cartridges:
1. During using dust extractor pleated filter cartridges, it is necessary to prevent the gas from cooling below the dew point in the bag, especially when using the dust extractor pleated filter cartridges 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.
Three, dust extractor pleated filter cartridges is closed, the filter air cut off, and then the electromagnetic pulse valve is opened, compressed air to expand in a short time in the upper box, into the filter bag, so that the filter bag expansion deformation vibration, and under the effect 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.
Five, dust extractor pleated filter cartridges with the extension of the filtering time, the dust layer on the filter bag has accumulated thick, and the resistance of the dust removal equipment has risen. When the resistance of the equipment rises to the set value, the dust removing device begins to remove the dust.
A cartridges device which separates dust from flue gas is called a dust collector or a dust removal device. 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.
