Filter Bag Phosphor Leak Detection
After the filter bag is installed in the precipitator, a “phosphor leak detection” must be performed on the bag filter, which is divided into the following steps:
A. When the main fan is operated at the designed air volume (the specific load varies depending on the form of the dust collector), the firefly will be stopped under the condition that the cleaning system is stopped.
The light powder is put into the opening of the air intake duct of the dust collector at a dosage of 5-10 g per square meter of filter area.
B. The position of the input port of the phosphor should be approximately 8m away from the air inlet of the dust collector (pipe distance). Otherwise, the phosphor should be considered.
From the dust collector exit or ash bucket access door.
C. After the phosphor is put into the dust collector, the fan should be kept running for at least 20 minutes to ensure that the phosphor is evenly distributed in the dust collector.
Each compartment on the filter bag.
D. After the phosphor has been put in, close the main fan, open the top cover of the dust collector, and carefully detect the board in the clean room with a fluorescent lamp.
Joints, filter bag and flower board interface bayonet and so on. During detection, the darker the surrounding environment, the more conducive leak detection work.
