Pleated Skeleton

The pleated skeleton is a support structure designed to adapt to the pleated dust collection bag, by adding radial folds or adopting a multi-prism structure on the basis of the traditional cylindrical skeleton, to provide uniform support for the pleated bag, to confirm that the filter bag remains stable after unfolding, the core solves the problem of poor adaptability between the traditional skeleton and the pleated bag, the filter bag is easy to deform, and is widely used in waste incineration, chemical, electric power and other scenarios that require dust removal efficiency and equipment space, and is the key component to realize the "miniaturization and effect" of the dust removal system.

Its structural design revolves around "adapting to pleated bags and optimizing airflow distribution": the main body is made of mild steel or stainless steel (selected according to working conditions, such as corrosion resistance (based on actual reports) scenes are 304 stainless steel), made by stamping and welding processes, and the surface is treated with galvanizing, spraying or anti-corrosion (based on actual reports) coating (to improve corrosion resistance); The skeleton as a whole is multi-prism (commonly 6~12 edges) or cylindrical with radial folds, and the spacing of the edges or folds is carefully matched with the number of folds of the folded bag, which confirms that each fold can be evenly supported after the bag is unfolded, so as to avoid the waste of filter area caused by local collapse; The top of the skeleton is equipped with a hanging cap and a position setting ring at the bottom, which is convenient for fixing with the flower plate of the filter bag room of the dust collector, and at the same time protects the verticality of the filter bag after installation and reduces the wear of the filter bag caused by airflow washing.

The core advantages are reflected in three aspects: first, to improve the filtration area, compared with the traditional cylindrical skeleton, the pleated skeleton can increase the filtration area of the pleated bag by 2~3 times (under the same filter bag length), under the condition that the equipment footprint remains unchanged, greatly improve the dust removal effect, the treatment air volume of the equipment is good, or reduce the volume of the equipment by 30%~50% under the same treatment air volume; The second is to protect the stability of the filtration, and the uniform edge/fold support can avoid excessive deformation or wrinkle adhesion of the filter bag during ash cleaning (such as pulse spraying), confirm that each filter area can work normally, and reduce the increase in resistance caused by local dust accumulation; The third is to extend the life of the filter bag, the contact area between the support structure and the bag is large and the force is uniform, avoiding the wear of the bag caused by local compression of the traditional skeleton, extending the service life of the filter bag by 20%~40%, and reducing the frequency of filter bag replacement and operation and maintenance costs.
