. be found. During traditional inspections, workers must be exposed to the harsh environment of the dust collector for a long time. This solution can also be widely used in leak detection of pipelines, leak detection of various gas boxes and containers and other equipment.
.
.
. .The diameter of the empty hole in the small bin before the flue gas enters the dust collector is at least
.
.
.
.. If the leak is detected in a new dust collector or a dust collector with a filter bag that has just been reinstalled, if the leak is detected in a used dust collector, turn off the online dust cleaning system This ensures the formation of dust cake on the surface of the filter bag, thereby forming a higher pressure difference on both sides of the bag. This forces the phosphor to pass through any small holes. If possible, visually check the cleanroom at dust loading and removal pressure so that the phosphor is not masked, which can highlight leaks.
.
.
.. Turn on the fan, and the amount of phosphor added sometimes needs to consider the pipe loss from the fan to the dust collector. After the phosphor is injected, the fan should continue to run for about
.
. . seconds, but not longer than
.
. . minutes. After the fan stops, use a special fluorescent lamp for dust collector leak detection. For pulse systems, open the top door and shine a light into the clean room during inspection.
.
. . (Note: Outdoor inspection must be done in the dark.) For rapping and blowback systems, inspection should be done inside. Start at the bottom and work around the support board.
.
.
.
.
. In areas with damage and holes, the phosphor will pass through and enter the clean air chamber and will Emit fluorescence. These fluorescently marked areas are leak points.
.

.
.
.
.. When all maintenance is completed, recheck with another color of phosphor to Make sure there are no leaks left. The second color will clearly show missed leaks. When phosphor is sprinkled into a baghouse, it will drift to the point of least resistance and eventually accumulate around the leak. The leak point can be easily found and the extent of the leak clearly known by simply shining it with a special fluorescent lamp.

. . . . How to use phosphor for leak detection To calculate the amount of phosphor, you can follow the following steps: per
.
. . square meter of filter material, the amount of phosphor is
.
. .g. For a blowing dust collector, taking into account the pipe loss, the amount of phosphor powder used per square meter of filter material is
.
.
.
. The amount of leak detection phosphor may also vary due to the distance between the fan and the ducting of the bag dust collector.

Note:
●If the filtration area of each chamber of the dust collector is already known, you can get the required kilograms of phosphor by simply dividing it.
●If it is a positive pressure system, the phosphor needs to be injected in front of the fan, and the amount of phosphor used will be determined according to the length of the pipe
