Introduction / 产品简介

Product introduction 产品介绍

Structural air leakage in the system, such as welding seams, metal sealing lids are not tight, and so on, unless the problem is very obvious, it is not easy to find. During the traditional inspection, the staff must be exposed to the harsh environment of the dust collector for a long time. This solution can also be widely used in pipeline leak detection, various gas tank containers and other equipment.
1. The diameter of the small hole in the silo before the flue gas enters the dust collector is at least 8cm. If the leak detection is a new dust collector or the dust collector of the newly reinstalled filter bag, please go directly to step 3.
2. If the used dust collector is checked, turn off the online dust removal system to ensure that dust cake is formed on the surface of the filter bag, thereby forming a higher pressure difference on the inside and outside of the bag. This can cause the phosphor to pass through any small holes. If possible, visually check the dust load and dedusting pressure of the clean air chamber, so that the phosphor is not covered, and the phosphor can show the leakage point.
3. Turn on the fan, and inject the phosphor with 0.5 kg / 100 square meters of filter material (in the positive pressure system, it should be injected before the fan). The amount of phosphor injected sometimes needs to consider the distance between the fan and the dust collector.
4. After the phosphor is injected, the fan should continue to run for about 45 seconds, but not longer than 1 minute. After the fan stops, check with the lamp. For the pulse system, the top door should be opened during the inspection and the lamp should be irradiated in the clean room. (Note: Outdoor inspections must be performed in the dark.) For rapping and anti-blowing systems, inspections should be performed internally. Start from the lower part and concentrate around the support plate.
5. In areas with breakage and holes, the phosphor will pass through and enter the scavenger, and it will fluoresce under the UV lamp. These fluorescently marked areas are the leak points.
6. When all repairs and maintenance are completed, recheck with another color phosphor to ensure that no leakage is left. The second color will clearly show the missing leak.
When the phosphor is sprinkled into the bag dust collector, it will float to the point of least resistance and eventually accumulate around the leak point. As long as it is irradiated with a special violet light, the leakage point can be easily found and the leakage level is clearly known.
Advantages of phosphor
1. Shorten downtime and maintenance time
2. Easy operation
3. Mature product technology
4. There are 12 different colors of fluorescent powder to choose from, suitable for different working conditions and multiple tests.
5. Specially designed the combination ratio of particles with different particle sizes to achieve the visible positioning effect.
6. No formaldehyde, safe for human body.
How to use phosphor
To calculate the amount of phosphor, you can proceed as follows: For every 93 square meters of filter material, the amount of phosphor is 1 pound. The filter area can be calculated using the following
formula:
Total filtration area (square meter) = [(diameter of filter bag (meter) * 3.14 * length of filter bag (meter))] * total number of filter bags Knowing the total filtration area of ​​each chamber, and then dividing by 93, you can get the required pounds of phosphor. The amount of fluorescent powder may also vary due to the distance between the fan and the filter bag filter.
Phosphor powder usage formula for leak detection test
formula:
Diameter of filter bag (cm) A * 3.14 * Length of filter bag (m) B / 100 * Number of filter bags C = filter area (sm) D
Filtration area (sm) D / 200 = phosphor amount (kg) E
E.g:
A = 12.7cm, B = 2.43m, C = 350pcs,
E = 12.7 * 3.14 * 2.43 / 100 * 350/200 = 1.7 kg
