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. In the case where the main fan is operated at designed air volume (specific loads vary depending on the form of the deduster) and the dust removal system is stopped, the fluorescent powder is put into the intake of the dust collector at a dosage of 5-10 g per square meter of filtration area. The opening of the pipe.
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 put into the ash bucket outlet or the ash bucket access door of the dust collector.
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 on the filter bags of the various chambers of the dust collector.
D. After the fluorescent powder is put in, close the main fan and open the top cover of the dust collector. Use the fluorescent lamp to carefully detect the joints of the flower board in the clean room, and the interface between the filter bag and the flower board. During detection, the darker the surrounding environment, the more conducive leak detection work.
