Now many bag filter are being reformed, but many companies do not know what the specific standard is? The national specific standard is 30 mg/m3, but many companies are defined at 15 mg/m3. It is a test that we put on the bag filter companies. How can we achieve this standard? Based on our many years of experience, we must pay attention to the following points:
1. The opening of the flower board must be cut using laser, so the precision is relatively high. The dust bag must be combined with this size to make, do not have deviation, if there is deviation, it will cause the dust bag to take off or there is gap between The passage of dust will affect the discharge of baghouse filters.
2. The board of the bag filter must be smooth, flat, and free from welding or gaps during welding. It is possible to use fluorescent powder or pressure test under certain conditions, especially for the welding of the middle box and the upper box of the bag filter. Sew, must not leak.
3. Use the dust bag to do laminating treatment, because the size of the dust particles allowed to pass through the retroperitoneal dust bag is only a few microns, a little larger dust can not pass through, and there is a design in the bag filter. At this time, the wind speed of the dust collector must be controlled. If the wind speed does not exceed 1 meter, the 15 mg dust emission requirement can be met.
