The dust collector board is also called a porous board and refers to a steel partition with the same size as the filter bag hole. In the flower board design, the distance of the filter bag hole is mainly arranged, and the distance is related to factors such as the bag diameter, the bag length, the nature of the dust and the filtration speed. If the distance between the hole and the hole is too tight, the bottom of the filter bag collides with each other, and the bottom part of the filter bag breaks within a few months of operation, and the air flow in the box may rise too fast, resulting in an increase in smoke and dust emissions. The filter load is too high and the cleaning power is insufficient.
According to our company’s engineers, the distance between the bag and the bag should be designed based on the length of the filter bag and the air flow rising speed. It should be at least 2/5 (not less than 40mm) in diameter of the filter bag. This design is reasonable and reliable.
The uniform arrangement of flower plate holes is suitable for small and medium-sized pulse dust collectors. The dense arrangement is suitable for large and medium-sized pulse dust collectors.
Board design considerations:
(1) The flower board should not only bear the system negative pressure, but also bear the weight of the filter bag, dust layer and bag cage. If there is deformation of the flower board, it may affect the straightness of the filter bag and the sealing effect at the bag mouth. The lower part of the flower plate should be reinforced.
(2) The dust collector board shall be smooth and smooth, and shall have no defects of deflection or unevenness. Its flatness deviation shall not be greater than 2/1000 of the length of the board. The peripheral area of the aperture needs to be smooth and free of burrs. The aperture tolerance of the filter bag fixed by the elastic expansion ring is ± 0.3mm. The deviation between the installation position and the theoretical position after the flower plate aperture machining should be less than 1.5mm. The flatness deviation is not more than 2/1000 of the length of the flower plate.
