We are filter cloth factory, and we have been produce filter cloth and dust filter bag for nearly 30 years.
Today we will discuss with you how to choose a right dust filter bag for pulse jet bag filter?
A, pulse bag filter skeleton vertical root of the root should be based on the material to filter with a reasonable match, and smooth and smooth without defects, have sufficient strength, vertical degree of industry standards, with the filter bag with good.
B, the pulse bag dust collector flat, flower plate hole surface smooth, flower plate hole from the box wall, flowerboard hole between a larger safe distance to prevent the board error, skeleton tilt, resulting in the filter bag The collision between the filter bag wear.
C, the pulse nozzle should be vertical, and should be concentrating with the flower plate hole, the error is less than 2mm.
D, pulse nozzle layout of the bag filter dust cleaning has an important impact, the pulse nozzle from the dust bag pocket has an optimal distance, too small, induced air flow is insufficient, and the bag bag bag at the mouth easily damaged; too large , The pulse gas flow pressure attenuation is too large, is not conducive to air flow to the bag. Specific pulse distance and pulse nozzle diameter, pulse air flow parameters, bag diameter relationship, to ensure that the pulse air flow and induced air volume is greater than the volume of the filter bag.
set the air distribution board, so that each box air distribution is relatively uniform, the location of the air distribution plate, the number of air distribution has a great impact.
F, pulse bag filter bag bottom and hopper should have a certain safety distance between the ash bucket should be high and low bit level meter, ash bucket too much dust, it should be timely unloading ash.
G, install the filter bag before the scene should be clean, filter bag frame blowing pipe and other facilities placed in order, dust removal equipment in the clean-up clean, the installation process should be well-organized, can not affect the filter installation of cross-operation.
H, in order to eliminate the flue gas may occur in the spark, the most effective precaution is to install the spark trap before the flue gas into the precipitator, the spark removed from the flue gas.
I, by the impact of regional climate differences, the requirements of the dust seal is better, the box insulation, to prevent local cooling equipment dust condensation.
J, dust bag installation is completed, dust removal equipment before the start of operation, should use lime powder, talcum powder on the filter bag pre-spraying. Filter bag effect is not only with the quality of the filter bag itself, but also with the reasonable design of the dust collector, as well as the installation of filter bags, operation and maintenance related.
